Description

CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a continuation in part of International Patent Application No. PCT/US2013/078110, filed Dec. 27, 2013, titled MODULAR STORAGE STRUCTURES, which claims priority to U.S. Provisional Patent Application No. 61/746,492, filed Dec. 27, 2012, titled MODULAR LIQUID STORAGE TANK, the contents of which are incorporated herein by reference in their entirety.

BACKGROUND

The present application generally relates to modular storage structures, and more particularly, but not exclusively, to modular storage structures arranged to store a liquid material.

Hydrocarbon exploration and extraction operations are conducted in places around the world, sometimes in very remote locations. Many of these operations involve very large volumes of fluids, equipment and/or other materials which need to be stored.

For example, hydraulic fracturing, or “fracking,” is a process in which large amounts of pressurized fluids fracture rock layers in order to release fossil fuels for extraction and recovery. Wellbore locations vary with rock formations, and some extraction operations may require temporary fluid storage near the wellbore's position. High volume liquid storage tanks may be necessary for storage of fracturing fluids, brine or process water during various oil field operations. These storage tanks may be designed to hold large quantities of liquid while fracking or other processes are underway. Structures for storing materials other than liquid may also be necessary. Further, the use of these structures may be implemented at sites other than where fracking occurs and/or in connection with operations other than fracking.

The subject matter claimed herein is not limited to embodiments that solve any disadvantages or that operate only in environments such as those described above. Rather, this background is only provided to illustrate one exemplary technology area where some embodiments described herein may be utilized.

DETAILED DESCRIPTION

For purposes of promoting an understanding of the described subject matter, reference will now be made to the following embodiments and specific language will be used to describe the same. It will nevertheless be understood that no limitation of the scope of the invention is thereby intended, such alterations and further modifications in the described subject matter, and such further applications of the principles of the invention as described herein being contemplated as would normally occur to one skilled in the art to which the invention relates.

The terms and words used in the following description and claims are not limited to the bibliographical meanings, but, are merely used by the inventor to enable a clear and consistent understanding of the invention. It is to be understood that the singular forms “a,” “an,” and “the” include plural referents unless the context clearly dictates otherwise. Thus, for example, reference to “a component surface” includes reference to one or more of such surfaces.

By the term “substantially” it is meant that the recited characteristic, parameter, or value need not be achieved exactly, but that deviations or variations, including for example, tolerances, measurement error, measurement accuracy limitations and other factors known to skill in the art, may occur in amounts that do not preclude the effect the characteristic was intended to provide.

The subject matter disclosed herein generally relates to modular structures. In one form, the modular structures may be configured to store a volume of liquid. More particularly, with general reference to FIG. 1, one non-limiting embodiment of a modular structure 100 is illustrated in a perspective view. The modular structure 100 includes a plurality of block components 200 that are configured to be removably coupled to one another. In the illustrated form, block components 200 are identical or substantially identical, although forms in which variations between block components 200 are present are also contemplated. Modular structure 100 also includes a plurality of base or anchor members such as components 300 configured to be positioned on a surface underlying the modular structure 100, and a plurality of elongate members 500 each removably coupled to a respective base component or anchor component 300. Each of elongate members 500 is further removably coupled to a respective one of a plurality of cap components 400. The elongate members 500 are further configured to couple vertically and laterally adjacent block components 200 to one another, further details of which will be provided herein below. A center member 600 is positioned in substantially the center of modular structure 100 and is positioned on or near the surface underlying modular structure 100. A plurality of cables 700 extend from center member 600 and each of cables 700 is removably coupled with a respective anchor component 300. For the sake of clarity, only a few of the above-mentioned components have been identified in FIG. 1.

In the illustrated form, block components 200 are arranged in a circular configuration and define an enclosed space. Although the modular structure 100 is generally circular, the components as described herein permit modular structures with configurations in a variety of geometric configurations and sizes. Additionally, although the illustrated modular structure 100 includes block components 200 stacked six rows high, it should be understood that modular structures with any number of rows of block components 200 are possible.

Turning now to FIGS. 2A-D, details of one non-limiting embodiment of the block component 200 will be provided. In the illustrated form, the block component 200 includes a body extending along an axis A₁ between a first end portion 204 and a second end portion 206. The block component 200 includes a first sidewall 208 opposite a second sidewall 210 and an upper surface 222 opposite a lower surface 224.

A first opening 212 on the first end portion 204 extends through the upper and lower surfaces 222, 224 of the block component 200. The first opening 212 is positioned between the first and second sidewalls 208, 210 as illustrated for example in FIG. 2C. The first end portion 204 includes a receptacle 216 configured to receive a second end portion of an adjacent block component which is the same or substantially identical to the second end portion 206 as illustrated for example in FIG. 2B. The receptacle 216 interrupts the first opening 212 into two spaced apart and aligned sections 212A and 212B. A second opening 214 extends through the second end portion 206 of the block component 200. The second opening 214 is positioned between the first and second sidewalls 208, 210. The first and second openings 212, 214 may also be referred to as hinge openings, although forms in which no hinge action is present between adjacent block components 200 are also envisioned. Non-illustrated embodiments include block components with multiple receptacles similar to receptacle 216 on the first and/or second end portions 204, 206 to hingedly engage multiple block components. In one particular form, the block component 200 is at least partially formed of a plastic polymer, although it should be appreciated that it may be formed of other materials as well.

Turning now to FIG. 2D, the first and second sidewalls 208, 210 and upper and lower surfaces 222, 224 define an interior chamber 218. The interior chamber 218 may be hollow or may be filled with a filler material (not shown). The filler material may be a foam material or a structural matrix. The filler material may include support members extending between the first and second sidewalls 208, 210 and/or the upper and lower surfaces 222, 224. Alternatively or additionally, the interior chamber 218 may be filled with water or any other liquid or other material or component configured to increase the structural stability of the block component 200 or modular structure 100. Forms in which block components 200 include a solid configuration and interior chamber 218 is absent are also contemplated.

As illustrated for example in FIG. 2D, the block component 200 includes reinforcing members such as cables 220 extending around the first and second openings 212, 214. The cables 220 are positioned within the interior chamber 218 and are configured to structurally reinforce block component 200. In non-illustrated examples, the cables 220 may be positioned exterior to the block component 200 or within the sidewalls 208, 210 and/or the upper and lower surfaces 222, 224 of the block component 200. When present, a variety of different types and numbers of cables 220 may be utilized in connection with the block component 200.

The block component 200 may be configured to withstand tensile stress without failing or breaking. For example, configurations of the block component 200 may have an ultimate tensile strength greater than 15,000 pounds-force per square inch. In some forms, configurations of the block component 200 may have an ultimate tensile strength greater than 6000 pounds-force per square inch. It should be appreciated however that alternative values for the tensile strength of the block component 200 are possible.

The modular structure 100 may be configured such that some rows of block components 200 include reinforcing members such as cables 220, and others do not. For example, the modular structure 100 of FIG. 1 may include reinforcing members such as cables 220 associated with block components 200 in the first, second and uppermost rows of block components 200 but not in any rows positioned between the second and uppermost rows of block components. In other configurations, reinforcing members such as cables 220 may be associated with each block component 200 or cables 220 may not be associated with any of the block components 200. Those skilled in the art will recognize that a number of different combinations of block components 200 with or without cables 220 are possible.

As illustrated for example in FIGS. 2A and 2C, the first and second end portions 204, 206 include arcuate or semi-circular configurations structured to facilitate pivotable engagement between adjacent block components 200. The first and second end portions 204, 206 are configured such that adjacent block components 200 may engage one another at a variety of different angles. For example, block components 200 may be engaged at or less than right angles with respect to each other, engaged substantially in a straight line with respect to each other, or at any configuration therebetween, just to provide a few non-limiting possibilities. Given the potential variation in the angular relationship between adjacent block components 200, it should be understood that block components 200 may be used to construct a modular structure having a variety of different sizes and shapes.

As illustrated for example in FIG. 2D, the block component 200 includes a molded handle 226 configured to facilitate manipulation and handling of the block component 200. Alternative arrangements for facilitating manipulation and handling of the block component 200 are possible. For example, the block component 200 may additionally or alternatively include an opening, indentation, handle, pin, loop, hooks, or any other features for facilitating manipulation and handling of the block component 200.

Alternative configurations for facilitating engagement of adjacent block components 200 are possible. For example, as illustrated in FIGS. 2E and 2F, a receptacle may not interrupt one of the openings into two spaced apart and aligned sections. As illustrated in FIG. 2E, adjacent block components 250A and 250B both include a first opening 252 and a second opening 254. Block components 250A and 250B are configured to be pivotably engaged with one another with opening 254 of block component 250A aligned with opening 252 of block component 250B. In such a configuration, it should be appreciated that the positioning of block components 250A and 250B may be switched to align opening 254 of block component 250B with opening 252 of block component 250A.

As illustrated in FIG. 2F, another alternative configuration includes adjacent block components 260A and 260B both including a first opening 262 and a second opening 264. Block components 260A and 260B are configured to be pivotably engaged with one another with opening 264 of block component 260A aligned with opening 262 of block component 260B. In such a configuration, block component 260B is rotated 180 degrees about its axis relative to block component 260A when the components are positioned adjacent to one another and pivotably engaged. Block component 260B may be rotated relative to block component 260A such that opening 264 may be positioned to be aligned with opening 264 of block component 260A. Block component 260A may also be similarly rotated relative to block component 260B.

Those skilled in the art will appreciate that other configurations of block components including one or more aspects of block components 200, 250 and 260 are possible. Although the modular structure 100 is illustrated with identical or substantially identical block components, it is contemplated that other non-illustrated forms of modular structure 100 may include one or more variations between one or more of the block components 200.

Turning now to FIG. 3A, further details regarding the anchor component 300 will be provided. More particularly, the anchor component 300 includes a base 306 extending between a first end portion 302 and a second end portion 304. The base 306 is configured to be positioned on a surface underlying the anchor component 300. The base 306 includes an opening 308 configured to receive an anchor stake 350 (FIG. 3B) or other anchor member to couple the anchor component 300 to the underlying surface. The base 306 also includes a plurality of connector openings 310, each configured to receive one end of a respective one of cables 700. It should be understood that the number of openings 308 and 310 in the anchor component 300 may deviate from the number shown in the illustrated form.

A connector member 312 is positioned on the base 306 between the first and second end portions 302, 304. The connector member includes two oppositely positioned slots 314. Each of the slots 314 includes a substantially vertical portion 313 and a transverse portion 315 extending orthogonally to the vertical portion 313.

As illustrated for example in FIG. 3A, elongate member 500 includes a pin 502 extending across a diameter of the elongate member. The elongate member 500 may be positioned such that the pin 502 is aligned with the slots 314. The pin 502 may be inserted into the vertical portions 313 of the slots 314. Subsequently, the elongate member 500 may be rotated relative to the anchor component 300 such that the pin 502 is positioned into the transverse portions 315 of the slots 314, thereby axially locking the elongate member 500 relative to the anchor component 300.

It should be understood that the number of slots 314 on the connector member 312 configured to receive pins or protrusions to secure the elongate member 500 to the anchor component 300 may deviate from the number shown in the illustrated form. The illustrated slots 314 are substantially L or J shaped, although it should be appreciated that alternatively configured slots 314 are contemplated. It is also contemplated that the engaging features of elongate member 500 and the anchor component 300 may be switched such that elongate member 500 includes a slot that receives a pin or protrusion of the anchor component 300. Further variations for coupling the elongate member 500 and the anchor component 300 are also possible however. For example, in one non-illustrated form, a threaded arrangement may be utilized to couple the elongate member 500 and the anchor component 300.

Turning to FIG. 3B, the anchor stake 350 is configured to couple the anchor component 300 to a surface underlying the anchor component, such as soil, dirt etc. The anchor stake 350 includes an engagement component 352 and an annular surface 354 positioned on a first end portion of a body 356. The anchor stake 350 may be composed at least partially of steel or of any other suitable material. The annular surface 354 is configured to secure the anchor stake 350 to the anchor component 300 when the anchor stake 350 is positioned through the opening 308 and at least partially into the surface underlying the anchor component 300. The engagement component 352 is configured to facilitate handling of the anchor stake 350, including removal of the anchor stake 350 from the underlying surface or the anchor component 300. Either or both of the engagement component 352 and the annular surface 354 may be welded to the anchor stake 350, or anchor stake 350 may be formed as a single component including these features.

Turning now to FIG. 4, where a number of blocks 200 have been labeled individually for the sake of clarity, further details regarding the relationship of blocks 200 relative to one another will be provided. More particularly, block components 200A, 200B and 200C are individually illustrated in FIG. 4 where like numerals refer to like features previously described. In the illustrated form, block components 200A, 200B and 200C are identical, although it should be understood that forms where the block components are not identical are also possible. The block components 200A, 200B and 200C are configured to be removably coupled to one another and include features corresponding to those described in connection with the block component 200 of FIGS. 2A-D.

Block components 200 are configured to be positioned adjacent to one another and removably coupled to one another when positioned in such a manner. For example, in FIG. 4 block component 200A and block component 200B are positioned laterally adjacent to one another and partially over the anchor component 300. While not previously discussed, it should be understood that the openings of the block components 200 may be sized and shaped to receive at least a portion of the anchor component 300. For example, in one form, the connector member 312 of the anchor component 300 and the openings of the block components 200 are sized and configured such that the connector member 312 is received in an opening of a block component 200. The second end portion 206 of block component 200A is positioned in the receptacle 216 of the first end portion 204 of block component 200B such that the second opening 214 of block component 200A is aligned with the first opening 212 of the block component 200B.

The block components 200 are further configured to be placed on top of one another and removably coupled with one another when positioned in such a manner. As illustrated for example in FIG. 4, block component 200C is positioned or stacked on top of block component 200A. In this configuration, opening 214 of block component 200C is aligned with opening 214 of block component 200A and opening 212 of block component 200C is aligned with opening 212 of block component 200A.

In one non-limiting, alternative configuration, block component 200C may be rotated 180 degrees relative to its illustrated position in FIG. 4 such that opening 214 of block component 200A is aligned with opening 212 of block component 200C. Multiple rows (also referred to as layers) of block components 200 may be stacked or positioned as described above to assemble modular structures of various heights, sizes and volumes.

The elongate member 500 is positioned through the aligned openings to removably couple blocks 200A, 200B and 200C. The elongate member 500 is rotatably coupled to the anchor component 300 as described above, and in such configuration a portion of the connector member 312 is positioned inside of elongate member 500. Similarly, in forms where at least a portion of connector member 312 extends into an opening of a connector block 200, the interaction between the elongate member 500 and the connector member 312 occurs, in whole or in part, inside the opening of the connector block.

With more particular reference to FIGS. 5A-5B for example, the elongate member 500 will be described in further detail. The elongate member 500 includes a substantially cylindrical body extending between a first end portion 504 and a second end portion 506. In the illustrated form, elongate member 500 includes a hollow interior 508, although it should be appreciated that forms in which elongate member 500 is solid along at least a portion of its length are possible. The pin 502 extends through an annular sidewall of the elongate member 500 and across the hollow interior 508 at the second end portion 506. In other forms, it is contemplated that the pin 502 is replaced with oppositely positioned projections or tabs that only extend partially into the hollow interior 508 from the sidewall of elongate member 500. The elongate member 500 is further configured to receive at least a portion of the anchor component 300 and the cap component 400 inside of the hollow interior 508 at the first and second end portions 504 and 506. Although not illustrated in FIG. 5A, the first end portion 504 of the elongate member 500 is configured substantially the same as the second end portion 506; i.e., it includes a pin extending across the hollow interior 508 or oppositely positioned projections or tabs that only extend partially into the hollow interior 508 from the sidewall of elongate member 500.

In alternative configurations, the elongate member 500 may be configured to be positioned inside one or both of the anchor component 300 and the cap component 400. In such configurations, opposite ends 510a and 510b of the pin 502 extending from the sidewall of elongate member 500 may be aligned with and positioned inside of the slots 314 of the anchor component 300 or a similar slot of the cap component 400. In other configurations, the pin 502 may not extend across the elongate member 500 and the elongate member 500 includes oppositely positioned protrusions or tabs in place of opposite ends 510a and 510b of the pin 502.

In certain non-illustrated forms, it is contemplated that anchor component 300 may be omitted from one or more portions of the modular structure 100. In these forms, the elongate member 500 may include a helical or screw-like configuration to engage the ground or another surface below the modular structure 100 instead of being configured to engage with the anchor component 300. In other forms where the anchor component 300 is absent from the modular structure 100, the elongate member 500 may be configured to be positioned on the surface underlying the modular structure 100 and then one or more additional anchor elements may anchor the elongate member 500 to the surface. Still, it should be appreciated that alternative forms for anchoring the modular structure 100 are possible.

The length of the elongate member 500 may be selected based on the desired height of the modular structure 100. For example, the length of the elongate member 500 may generally correspond to the cumulative height of the number of layers or rows of block components 200 of the modular structure 100. In one technique for assembling the modular structure 100, the elongate member 500 in inserted into aligned openings of block components 200 after the final height of the modular structure 100 has been obtained, although other variations are possible.

Turning to now FIG. 5C, an alternatively configured elongate member 550 is illustrated. Elongate member 550 may be used in modular structure 100 in addition to or in lieu of elongate member 500. Elongate member 550 includes a substantially cylindrical body extending between a first end portion 554 and a second end portion 556 and defining a hollow interior 558. The first and second end portions 554 and 556 include slots 560 substantially corresponding to the structure and functionality of slots 314.

The elongate member 550 is configured to engage an alternatively configured anchor component 570. The anchor component 570 substantially corresponds in functionality and structure to anchor component 300, but includes an alternatively configured connector member 572. The connector member 572 includes an opening 574 that is configured to receive the elongate member 550 and a pin 576 configured to engage the slots 560 of the elongate member 550 to provide an axially restrained relationship between the elongate member 550 and the anchor component 570 when the elongate member 500 is inserted into and rotated relative to the anchor component 570.

The elongate member 550 is further configured to engage an alternatively configured cap component 580 which includes a connector member 582 configured like the connector member 572. Although not shown, the connector member 582 includes a pin configured to engage the slots 560 of the elongate member 550 to provide an axially restrained relationship between the elongate member 550 and the anchor component 572 when the elongate member 500 is inserted into and rotated relative to the cap component 580.

A plurality of sleeve members 590 are also illustrated in FIG. 5C. The sleeve members 590 are substantially cylindrical and define an opening 592 configured to receive the elongate member 550, and the sleeve members 590 are further configured to engage with one another such that openings 592 are aligned with one another. For example, in one form the sleeve members 590 may be configured to be simply positioned on top of one another. In another form, the sleeve members 590 may be configured to interengage with one another to provide a locking or locked arrangement therebweteen. It should be appreciated that the inner diameter of the opening 592 is configured to facilitate placement of the elongate member 550 therein. In addition, the sleeve members 590 may also be used with the elongate member 500 provided that the elongate member 500 is sized to be inserted through the sleeve members 590.

When sleeve members 590 are employed in the modular structure 100, they may be individually placed in aligned openings of block components 200. In this manner, the sleeve members 590 can be individually stacked as successive rows of block components 200 of modular structure 100 are formed. More particularly, as a row of block components 200 is formed, a sleeve member 590 can be positioned in aligned openings of the block components 200, and this process can be repeated until the final height of the modular structure 100 is reached. It is also contemplated that two or more sleeve members 590 may be positioned at the same time, or that the sleeve members 590 are all positioned through aligned openings of the block components 200 after the final height of the modular structure 100 is obtained. When one or more sleeve members 590 are positioned in aligned openings of the block components 200 before the final height of the modular structure 100 is reached, these sleeve members 590 provide provisional coupling and alignment of the block components 200 until the elongate member 500 is positioned through the sleeve members 590. In this respect, once the modular structure 100 reaches its final height and the sleeve members 590 have been positioned, the elongate member 500 or 550 may be inserted through the sleeve members 590 and into engagement with an anchor component 300. The positioning of the elongate member 500 in this manner further secures the coupling of the block components 200 to one another.

Turning to now FIG. 5D, a plurality of elongate members 520 are illustrated. The elongate members 520 may be used in the modular structure 100 in addition to or in lieu of elongate member 500 or 550. The elongate members 520 extend between first and second end portions 524 and 526. The first end portions 524 include slots 522 and the second end portions 526 include a pin 528. A number of elongate members 520 are individually labeled as 520A, 520B and 520C for the sake of clarity.

Anchor component 530 substantially corresponds in structure to anchor component 570 and includes a connector member 532, opening 534 and pin 536. The configuration also includes a cap component 540 that substantially corresponds to the cap component 580 and includes a connector member 542.

The elongate members 520 are configured to engage with each other, the anchor component 530 and the cap component 540. For example, the elongate member 520A is configured to be partially inserted into opening 534 of the anchor component 530 with the slots 522 engaging the pin 536. Upon rotation of the elongate member 520A relative to the anchor component 530, the slots 522 and the pin 536 interact to provide an axially restrained or locked relationship between the elongate member 520A and the anchor component 530. Elongate member 520B is configured to be positioned on top of the elongate member 520A and may be rotatably coupled therewith. More particularly, the pin 528 of elongate member 520A may be positioned into the slot 522 of elongate member 520B and the elongate member 520B may be rotated relative to elongate member 520A to removably couple the two. The cap component 540 may be similarly coupled to the uppermost one of elongate members 520. When the elongate members 520 are employed in the modular structure 100, they may be individually placed in aligned openings of block components 200. For example, a first elongate member 520 may be placed through aligned openings and engaged with an anchor component. In this manner, the elongate members 520 can be stacked as successive rows of block components 200 are formed on modular structure 100. Once the modular structure 100 reaches its final height, a final elongate member 520 may be coupled with the next to final elongate member 520 and then the cap component 540 may be coupled with the final elongate member 520. It should be understood that forms in which a single elongate member 520 is positioned through aligned openings of block components 200 and engaged with an anchor component and a cap component are also possible.

While not previously described, it should be appreciated that modular structure 100 may include one or more reinforcing members to help provide stability and strength to structure 100. For example, as illustrated in FIG. 6, the modular structure 100 includes reinforcing members such as structural cables or bands 512 configured to add stability to the modular structure 100. In one aspect, the reinforcing members in the form of cables 512 are positioned above and below a respective block component 200. For example, a first cable 512 may be placed relative to elongate members 500A and 500B followed by positioning of a block component 200 on top of the first cable and a second cable 512 on top of the block component 200. It should be understood that alternative arrangements are possible however. For example, a single cable 512 may be employed for each row of block components 200. As illustrated, the reinforcing cables 512 extend around two elongate members 500A and 500B and are configured to structurally connect the elongate members 500A and 500B. While not illustrated, it should be understood that cables 512 may connect more than two elongate members 500 or that more than two elongate members 500 may be connected by one or more than one cable 512. The cables 512 may also be employed in forms where elongate members 520 or 550 are utilized. The cables 512 may be formed of steel or any other suitable materials. In one exemplary form, the reinforcing cables 512 may be formed by plurality of braided steel fibers.

Turning now to FIG. 7, the cap component 400 will be described in further detail. The cap component 400 includes a body 406 including connector openings 410, each configured to receive one end of a respective cable 700 (discussed in further detail below). In the illustrated form, the connector openings 410 substantially correspond in size and configuration to the connector openings 310 of the anchor component 300. A connector member 412 is positioned on the body 406 and substantially corresponds in structure and function to connector member 312. The connector member 412 includes two oppositely positioned slots 414. Each of the slots 414 includes a vertically extending portion 413 and a transverse portion 415 which extends substantially orthogonally to the vertical portion 413, although other variations are contemplated.

The cap component 400 is configured to rotatably couple or engage the elongate member 500 in an arrangement similar to that described above with respect to the anchor component 300. It should be appreciated that the cap component may also be coupled to elongate members 520 or 550 in a similar fashion. After the block components 200, anchor components 300, and elongate members 500 are positioned and assembled as described above, each of the cap components 400 may be rotatably coupled to one of the elongate members 500. In this arrangement, the body 406 may engage with or be positioned in close proximity to an uppermost block component 200 and provide a lock or clamp on the block components in combination with the anchor component 300. Similarly, amongst other things, this arrangement prevents axial dislocation of the block components from the elongate member 500.

With reference to FIG. 8, for example, the cable 700 will be described in further detail. Cable 700 includes a connector 702 positioned on a first end 706 and a connector 704 positioned on a second end 708. The connectors 702, 704 are keyed to fit into corresponding connector openings of the anchor components 300, cap components 400 and/or center member 600. The connector openings 310, 410, 610 (FIG. 9A) and 660 (FIG. 9B) are oriented such that the connectors 702, 704 may be inserted into the connecting openings in a first orientation and then rotated to a second orientation in which the connectors become engaged with or locked in the connector openings. For example, in the illustrated form, the connectors 702, 704 are substantially square-shaped, and the connector openings 310, 410, 610, and 660 are substantially square shaped. In this arrangement, the connectors 702, 704 may be turned about 45 degrees or so after insertion into the connector openings 310, 410, 610, and 660 to provide a locking arrangement therebetween. However, it should be understood that other locking arrangements between connectors 702, 704 and connector openings, 310, 410, 610, and 660 are possible.

The cable 700 also includes attachments 710 and 712 configured to couple the connectors 702, 704 with a cable section 714. The cable 700 may also include one or more optional tensioning devices that are not illustrated for clarity. The tensioning devices may be turnbuckles or any other suitable devices configured to adjust the tension of cable 700. The tensioning devices may be optionally added to the cable 700 at any feasible position.

With reference to FIG. 9A, for example, the center member 600 will be described in further detail. The center member 600 is substantially circular and includes a plurality of connector openings 610 around the outside edge of the center member 600. The connector openings 610 substantially correspond to the connector openings 310 and 410 and are configured to receive a connector 702 or, 704 of a cable 700. The center member 600 also includes stake openings 608 positioned interior to the connector openings 310. The stake openings 608 substantially correspond to the stake openings 308 and each is configured to receive an anchor stake 350. For the sake of clarity, only a few of the stake openings 608 and connector openings 610 are labeled in FIG. 9A.

In alternative configurations, it should be appreciated that the center member 600 may include a number of stake openings 608 or connector openings 610 that deviates from the illustrated form. The positioning of stake openings 608 or connector openings 610 may also vary in non-illustrated forms. In one non-limiting form, the number of connector openings 610 may be selected to correspond to the number of anchor components 300 of the modular structure 100. However, forms in which the center member 600 includes a greater or lesser number of connector openings 610 than there is anchor components 300 in the modular structure 100 are also possible.

In the illustrated form, the center member 600 is positioned in substantially the center of the modular structure 100. The center member 600 is configured to attach to cables 700 to provide structural support for the modular structure 100. The length of cable 700 roughly corresponds to the radius of the modular structure and the length of the cable section 714 may be selected based on the size of the modular structure 100.

In non-illustrated configurations a center member 600 may not be included and each of the cables 700 may be extend between a pair of anchor components 300 or between a pair of cap components 400. In such configurations, each anchor component 300 or cap component 400 may be coupled to more than one cable 700 to provide additional structural support. Such configurations may be generally circular or any geometric configuration and/or size. In one form for example, the modular structure 100 may be substantially rectangular and a plurality of cables 700 may be coupled to each anchor component 300 or cap component 400 and extend across the modular structure 100 where each of the plurality of cables 700 is individually coupled with a respective anchor component 300 or cap component 400.

Turning to FIG. 9B, the modular structure 100 may also include a support element 650, which is not illustrated in FIG. 1. The support element 650 includes an elongate section 662 extending between a first end 652 and a second end 654. A base member 656 is positioned on the first end 652 and a top member 658 is positioned on the second end 654. The top member 658 generally corresponds in structure and function to center member 600 and includes connector openings 660. The second end 654 may also include spoke members 664 extending from the top member 658 to the elongate section 662.

The base member 656 is configured to be positioned substantially in the center of the modular structure 100 on a surface underlying the support element 650. The underlying surface may be a liner positioned inside of the modular structure, the center member 600, or the ground.

The top member 658 is configured to be removably coupled to a first end of a plurality of the cables 700 with the other end of each cable 700 being coupled to a cap component 400. This support configuration is similar to that of the center member 600 but positioned generally near the top of the modular structure 100 instead of near the bottom of the modular structure 100.

The support element 650 coupled to the cap components 400 with cables 700 may be generally referred to as a support element system. The support element system may be configured to provide additional structural support for the modular structure 100. Although not illustrated, the support element system may also provide support for a cover for the modular structure 100. Additionally or alternatively, the support element 650 may provide support for a vapor control system for the modular structure 100.

Although not illustrated, the support element 650 may be configured such that the elongate section 662 may be removably coupled to the first and/or second ends 652, 654. The elongate section 662 and the first and/or second ends 652, 654 may include removable coupling features similar to the rotatable coupling configuration of elongate member 500 with anchor components 300 and/or cap components 400.

Further details regarding alternative embodiment block components and modular structures will now be provided in connection with FIGS. 10A-10F. Turning first to FIG. 10A, an alternative embodiment block component 1200 and an alternative embodiment reinforcing member 800 are illustrated in a perspective view. The block component 1200 is similar to the block component 200, and like numerals have been used in connection with like features previously described in connection with the block component 200.

In the illustrated form, the block component 1200 includes a pair of receptacles 1270 (only one is shown) structured to receive at least a portion of a reinforcing member 800. The receptacles 1270 are positioned opposite one another on respective upper and lower surfaces 222, 224 of the block component 1200. Forms in which the block component 1200 only includes a single receptacle 1270 positioned on one of the upper and lower surfaces 222, 224 are also possible. The receptacles 1270 extend around the first opening 212 of the block component 1200 and toward the second opening 214 of the block component 1200. However, since the second opening 214 is positioned medially of the upper and lower surfaces 222, 224, the receptacles 1270 do not extend around the second opening 216. In addition, the receptacles 1270 are positioned inwardly from lateral edges of the block component 1200 such that portions of the upper and lower surfaces 222, 224 are positioned on opposite sides of the receptacles 1270, although other variations are contemplated. As shown for example, the receptacle 1270 formed in upper surface 222 includes a surface 1272 recessed with respect to the upper surface 222. The recessed surface 1272 is positioned between first and second portions 1274, 1276 of the upper surface 222. The first portion 1274 extends along the first sidewall 208 and the second raised portion 1276 extends along the second sidewall 210. While not shown, it should be appreciated that the receptacle 1270 on the lower surface 224 of the block component 1200 is similarly configured.

The reinforcing member 800 includes a body 802 extending between a first end portion 804 and a second end portion 806. The first end portion 804 includes an arcuate configuration which transitions from a linear configuration of the body 802, and the second end portion 806 also includes an arcuate configuration which transitions from the linear configuration of the body 802. Generally speaking, in the illustrated form the configuration of the first and second end portions 804, 806 of the reinforcing member 800 corresponds to the configuration of the first end portion 204 of the block component 1200. Similarly, when a pair of the block components 1200 are engaged with one another in end-to-end fashion (i.e., with a first end portion 204 engaged with a second end portion 206), the first end portion 804 of the reinforcing member 800 is associated with the first end portion 204 of a first one of the block components 1200 and the second end portion 806 is associated with the first end portion 204 of a second one of the block components 1200.

A first opening 812 extends through the first end portion 804 of the reinforcing member 800, and a second opening 814 extends through the second end portion 806 of the reinforcing member 800. As illustrated for example in FIG. 10A, the first opening 812 may correspond in size and shape to the first opening 212 of the block component 1200 and the second opening 814 may correspond in size and shape to the second opening 214 of the block component 1200. The reinforcing member 800 and/or the receptacles 1270 are generally dimensioned to facilitate positioning of at least a portion of the reinforcing member 800 in a receptacle 1200. For example, the reinforcing member 800 may generally include a width and thickness which facilitate positioning at least a portion thereof in the receptacles 1270. In one non-limiting aspect, the reinforcing member 800 may include a width that facilitates its positioning between the portions of the upper and lower surfaces 222, 224 positioned on opposite sides of the receptacles 1270. In addition, the reinforcing member 800 may include a thickness dimensioned such that the reinforcing member 800 is flush with or positioned below the upper or lower surfaces 222, 224 when it is positioned in a receptacle 1270. Forms in which the reinforcing member 800 includes a thickness dimensioned such that a single reinforcing member 800 is positioned in receptacles 1270 of a pair of adjacent block components 1200 stacked one on top of the other are also possible. In these forms, the reinforcing member 800 includes a thickness which is greater than the depth of the receptacles 1200.

Another alternative embodiment block component 2200 is illustrated in a perspective view in FIG. 10B. The block component 2200 is similar to the block components 200 and 1200, and like numerals have been used in connection with like features previously described in connection with the block components 200 and 1200. In the illustrated form, the block component 2200 includes an offset base portion 2280 extending from the first sidewall 208 between the first and second end portions 204, 206. Amongst other things, the base portion 2280 may facilitate in preventing the contents held by a modular structure including the block component 2200 from moving under and/or displacing the block component 2200.

As illustrated, for example, the base portion 2280 extends between a first end 2284 and a second end 2286 and includes a portion 2282 having an arcuate or rounded configuration which extends from the first sidewall 208 of the block component 2200 to an edge 2288 of the base portion 2280. More specifically, the portion 2282 defines an arcuate surface extending from a first plane in which the first sidewall 208 extends and a second plane in which the lower surface 224 extends. In other non-illustrated configurations, the portion 2282 may define a planar surface which extends between and transversely to the first and second planes. The lower surface of the base portion 2280 is aligned with the lower surface 224 such that positioning of the block component 2200 on a surface underlying the block component involves placement of both the lower surface 224 and the lower surface of the base portion 2280 on the underlying surface. In form illustrated in FIG. 10B for example, the first and second ends 2284, 2286 of the base portion extend parallel to one another and orthogonally to the sidewall 208. However, it should be understood that forms in which the first and second ends 2284, 2286 extend transversely to one another and to the sidewall 208 are possible in order to facilitate non-linear positioning of a number of adjacent block components 2200. Further details of an arrangement of this nature are provided below in connection with FIG. 10F.

FIGS. 10C-10F illustrate a modular structure 1100 that includes block components 1200 and 2200. As illustrated in FIG. 10C for example, the modular structure 1100 includes block components 2200A and 2200B which are coupled together in end-to-end fashion. The modular structure 1100 also includes block components 1200A-D with block components 1200A and 1200B engaged in end-to-end fashion with one another and positioned on top of the block components 2200A and 2200B, respectively. The block components 1200C and 1200D are engaged in end-to-end fashion with one another and positioned on top of the block components 1200A and 1200B, respectively. It should be appreciated that the modular structure 1100 could have any number of the block components 1200 and 2200 engaged with and stack relative to one another to form a variety of different configurations of the structure 1100.

FIGS. 10D and 10E illustrate details of assembly of the modular structure 1100 and of elements of the modular structure 1100 that are not numerically identified in FIG. 10C. In addition to the block components 1200A-D and 2200A-B, the modular structure 1100 includes a plurality of base members 830A-C, elongate members 820A-C and 822A-F, cap members 840A-C, and reinforcing members 800A-H. In non-illustrated forms, it is contemplated that one or more of the elongate members 500, 520, or 550 may be used in addition to or in lieu of one or more of the elongate members 820A-C and 822A-F, that the anchor component 300 may be used in addition to or in lieu of one or more of the base members 830A-C, and that the and cap members 840A, 840B may be used in addition to or in lieu of one or more of the cap members 840A-C.

In the illustrated form, the base members 830A-C are substantially identical to the cap members 840A-C and may be used interchangeably. The base members 830A-C, the cap members 840A-C and the elongate members 820A-C and 822A-F are configured for a press fit engagement with one another, although forms utilizing alternative locking arrangements between these components such as bayonet locking or ball-detent locking are contemplated. For example, the base members 830A-C each include an insertion portion and a collar portion. These elements are identified by numerals 832A-B and 834A-B, respectively, in FIG. 10E in connection with the base members 830A and 830B. The insertion portions of the base members 830A-C are configured to be positioned inside a hollow portion of the elongate members 820A-C such that the ends of the elongate members 820A-C come into contact with the collar portion of the base members 830A-C.

The elongate members 822A-F each include an insertion portion positioned opposite of a hollow portion. These elements are identified by numerals 824 A, B, D and E and 826 A, B, D and E, respectively, in FIG. 10E in connection with the elongate members 822 A, B, D and E. The insertion portion of the elongate members 822A-C is configured to be positioned in a hollow portion of a respective elongate member 820A-C, and the insertion portion of the elongate members 822D-F is configured to be positioned in the hollow portion of a respective elongate member 822A-C. The cap members 840A-C, which are identical to the base members 830A-C, include an insertion portion and a collar portion and the insertion portion is configured to be positioned in the hollow portion of a respective elongate member 822D-F such that the ends of the elongate members 822D-F engages with the collar portion. It should be appreciated however that alternative arrangements for engaging the base members 830A-C, the elongate members 820A-C and 822A-F, and the cap members 840A-C are possible and that a different number of these components could be present depending on the desired size and configuration of the modular structure 1100.

The base members 830A, 830B include corresponding connecting portions 832A and 832B. The connecting portion 832A may be positioned through the first opening 812 of the reinforcing member 800A to engage the reinforcing member 800A with the connecting portion 832A. Similarly, the connecting portion 832B may be positioned through the second opening 814A of the reinforcing member 800A to engage the reinforcing member 800A with the connecting portion 832B. The elongate member 820A may be positioned through the first opening 812 of the reinforcing member 800A into engagement with the connecting portion 832A of the base member 830A. The elongate member 820B may be positioned through the second opening 814A of the reinforcing member 800A into engagement with the connecting portion 832B of the base member 830B.

One non-limiting technique for assembling the modular structure 1100 involves the following steps, although other variations in the assembly are contemplated. The base members 830A-C are positioned and the reinforcing member 800A is engaged with the base members 830A-B with the collar portion of the base members 830A-B being positioned in the first and second openings 812, 814 of the reinforcing member 800A. The reinforcing member 800E is positioned over the reinforcing member 800A at the base member 830B and engaged with the base members 830B-C with the collar portion of the base members 830B-C being positioned in the first and second openings of the reinforcing member 800E.

After the reinforcing members 800A and 800E are placed in engagement with the base members 830A-C, the block component 2200B may be place over the reinforcing member 800E with a portion of the base member 830B extending into the opening 212 of the block component 2200B and the opening 214 of the block component 2200B positioned in line with the base member 830C. The block component 2200A may then be positioned over the reinforcing member 800A with the opening 214 thereof aligned with the opening 212 of the block component 2200B and a portion of the base member 830A extending into the opening 212 thereof. In this configuration, at least a portion of the reinforcing members 800A, 800E is positioned in the receptacles 1270 on the lower surfaces of the block components 2200A and 2200B.

Once the block components 2200A and 2200B have been positioned accordingly, the elongate member 820A may be positioned through the first opening 212 of the block component 2200A and into engagement with the base member 830A; i.e., with the insertion portion of the base member 830A received in the elongate member 820A. The elongate member 820B may be positioned through the aligned first opening 212 of the block component 2200B and the second opening 214 of the block component 2200A and into engagement with the base member 830B in a similar fashion. The elongate member 820C may be positioned through the second opening 214 of the block component 2200B and into engagement with the base member 830C as described in connection with the elongate member 800A and the base member 830C.

Following placement of the elongate members 820A-C, the reinforcing member 800B may be positioned over the block component 2200A with a portion of the elongate member 820A extending through the opening 812 thereof and a portion of the elongate member 820B extending through the opening 814 thereof. The reinforcing member 800B is also positioned such that at least a portion thereof is received in the receptacle 1270 on the upper surface of the block component 2200A. The reinforcing member 800F is then positioned over the block component 2200B with a portion of the elongate member 820B extending through the opening 812 thereof and a portion of the elongate member 820C extending through the opening 814 thereof. The reinforcing member 800B is also positioned such that at least a portion thereof is received in the receptacle 1270 on the upper surface of the block component 2200B, and such that a portion thereof is positioned over and overlaps with the reinforcing member 800B around the elongate member 820B. The block components 1200A and 1200B may then be positioned over the reinforcing members 800B and 800F in a manner similar to that described in connection with the positioning of the block components 2200A and 2200B, resulting in the reinforcing members 800B and 800F being positioned between the block components 2200A and 1200A and 2200B and 1200B, respectively.

Following positioning of the block components 1200A-B, the elongate member 822A may be inserted through the first opening 212 of the block component 1200A and the insertion portion thereof may be positioned into engagement with the hollow portion of the elongate member 820A. The elongate members 822B-C may be similarly inserted through openings in one or both of the block components 1200A and 1200B and the insertion portions thereof may be brought into engagement with the elongate members 820B-C, respectively.

The remaining block components 1200C-D, elongate members 822D-F, and reinforcing members 800C-D and 800G-H may be added to the modular structure 1100 in a manner similar to that previously described with respect to like components. Once these components have been added to the modular structure 1100 and no additional rows of the block components 1200 are desired, the cap members 840A-C may be positioned to engage with corresponding elongate members 822D, 822E and 822F.

In FIG. 10F, it can be seen that the base portions 2280A and 2280B of the block components 2200A and 2200B interface with one another when the block components 2200A and 2200B are arranged in a non-linear configuration. The base portion 2280A includes a first end 2284A and an oppositely positioned second end 2286A engaged with a first end 2284B of the base portion 2280B. The base portion 2280B also includes a second end 2286B positioned opposite the first end 2284B. As illustrated for example in FIG. 10F, the ends 2284A-B and 2286A-B of the base portions 2280A-BC are angled relative to the corresponding body of the block component 2200A-B to permit the block components 2200A-B to be angled with respect to one another, for example, to form a circular modular structure such as the modular structure 1100. This arrangement also facilitates the formation of a continuous or substantially continuous surface by the base portions 2280A-B on which, for example, a liner could be positioned.
