2. Description of the Related Art
Most residential homes are built using wood frames. Typically, wood boards in 2×4 or 2×6 configurations constitute residential frame construction. Using wood provides a contractor with several benefits. Most residential construction workers are trained to build house frames using wood. Therefore, using wood contributes to lower labor costs. Furthermore, wood is adaptable to any job site. For example, increasing or decreasing the number of 2×4's or 2×6's allows an increase or decrease in the strength of a particular frame. For these reasons, wood has become the accepted standard in residential frame construction because of its commonality and adaptability. Using wood in residential frame construction, however, has several disadvantages. First, wood tends to be expensive. Also, the character of wood makes it more susceptible to the elements. Third, a large variability exists in the quality of wood boards which contributes to higher costs. Finally, wood frames tend to be heavy and moving such frames can become highly cumbersome.
When used in space-frame construction, steel overcomes many of the disadvantages of wood. Steel is fireproof and resistant to termites. Furthermore, steel will not rot, mold, or warp because it is resistant to moisture. Steel also acknowledges environmental concerns because it is recyclable. However, using steel in place of wood framing, often, has been cost prohibitive. Finding residential construction workers trained in using steel is difficult. In addition, the construction techniques used in steel space-frame construction are fundamentally different from those used in wood construction. Having to train workers on how to use steel is a time consuming process. Consequently, expenses saved on steel materials may be lost in labor costs. Finally, various gauges of steel must be used to meet the structural strength requirements of a particular job site, which is time consuming and once again, contributes to increased labor costs.
Accordingly, a steel space-frame construction system that incorporates the advantages of wood based systems while eliminating the problems with traditional steel space-frame construction.
SUMMARY OF THE INVENTIONIn accordance with the present invention, a steel space-frame construction system is modular, thereby incorporating the advantages of wood based systems, while eliminating problems plaguing traditional steel space-frame construction. Furthermore, the system's modularity eliminates the need for different gauges of steel and, therefore, lowers the costs of any building project. Component modularity allows the meeting of strength and stability requirements through component configuration and not heavier steel. Specifically, the modular system allows for the stacking of multiple studs to increase strength. This stacking eliminates the need to use different gauges of steel when confronted with different strength requirements of a particular job. The system's modularity allows workers trained in wood framing to adapt very quickly to the steel construction of the present invention, which lowers the cost of labor.
The steel space-frame construction system includes studs, blocks, at least one channel, and, if necessary, at least one top cap. A first end of a first stud is placed in a channel and secured thereto. At least one block is secured to the first stud. A first end of a second stud placed in the channel, and the second stud is secured to the at least one block and channel. The at least one block provides a predetermined fixed spacing between the first stud and the second stud and further provides lateral stability while resisting distortion or racking when loaded axially. Additional studs and blocks are secured together until the end of the channel is reached. The studs are also secured to the channel. A top cap or other blocks are secured to the studs at a second end thereof. The channel is repositioned so that the opposite sides of the studs, blocks, channel, and top cap or other blocks may be secured together, thereby forming a space-frame.
A stud includes a first side, a second side, and a cross-member therebetween. The first side and the second side each include a recess adapted to receive at least one fastener therein such that the fastener does not protrude exterior to the recess. The first side and the second side further each terminate in a curved edge, thereby strengthening the stud.
A block includes a first side, a second side, and a cross-member therebetween. The first side and the second side each terminate in a curved edge that strengthens the block. The first side includes a tab at a first end and a tab at a second end that facilitate connection of the block between studs. Likewise, the second side includes a tab at a first end and a tab at a second end that facilitate connection of the block between studs. Each tab includes a recess adapted to fit within the recess in the first side and second side of a stud such that a fastener securing the tab to the stud does not protrude exterior to the recess in the tab. Each tab further includes an indentation that functions as a guide for a fastener inserted through the tab.
The steel space-frame construction system of the present invention improves over existing methods of building because, although there are steel members presently used in construction, previously there was no method or apparatus that provided lateral stability to a steel space frame during the assembly phase. The steel space-frame construction system allows for lateral stability when erecting a structure due to the ability of adjacent studs connected by at least one block to resist distortion when loaded axially.
The steel space-frame construction system of the present invention improves over existing methods of building because, although there are wooden members presently used in construction, previously there was no method or apparatus that prevented racking of partially constructed or incomplete walls framed from wood due to the inability of a fastener and stud to resist lateral movement. The steel space-frame construction system allows for lateral stability when erecting the structure due to the ability of adjacent studs connected by at least one block and fastened with a fastener to resist distortion or racking when loaded axially.
The steel space-frame construction system of the present invention improves over existing methods of building because, although there are steel members presently used in construction, previously there was no method or apparatus that provided for a self-squaring mechanism of studs and blocks. In particular, adjacent studs are squared through the connection of at least one block therebetween.
The steel space-frame construction system of the present invention improves over existing methods of building because the first and second sides of each stud and block terminate in a curved edge that provides each stud and block with additional strength and the ability to resist axial loading.
The steel space-frame construction system of the present invention improves over existing methods of building because the first and second sides of each stud include a recess that furnishes a single plane surface free of protrusions on which to attach sheetrock, gypsum board, paneling, or other wall surface material thereby avoiding penetrations into the surfaces could result in apparent distortions. Consequently, although there are steel members presently used in construction, previously there was no method or apparatus to conceal the heads of fasteners in a manner that prevented protrusions or telescoping of fasteners from the plane of the stud.
The steel space-frame construction system of the present invention improves over existing methods of building because each tab on a block includes a recess that fits within a recess of a stud such that fasteners securing the tab to the stud do not telescope through the plane of the stud, which results in penetrations into wall surface material that create apparent distortions of the surface. The steel space-frame construction system of the present invention improves over existing methods of building because each tab on a block further includes an indentation that establishes a point of purchase for a fastener to be placed consistently and precisely.
The steel space-frame construction system of the present invention improves over existing methods of building because, although there are steel and wood members presently used in construction, previously there was no method or apparatus providing a modular building system and method that permitted the fabrication of steel space-frames rigid enough to facilitate ease of handling during the fabrication and construction phases. Essentially, the steel space-frames are sufficiently rigid to allow fabrication, partial or complete, of wall structures in one location or facility and transport of those structures to another location or facility for use in construction. The steel space-frame construction system accordingly allows structurally stable steel space-frames to be fabricated and transported without the risk of damage or destruction existing with other methods of construction
As required, detailed embodiments of the present invention are disclosed herein; however, it is to be understood that the disclosed embodiments are merely exemplary of the invention, which may be embodied in various forms. Figures are not necessarily to scale, and some features may be exaggerated to show details of particular components or steps.
The channel 16 provides the base of the space-frame 50, and when used the top cap 17 will provide the crown. The channel 16 consists of a top face 22, a bottom face 60, a side 21, and a side 23. The top cap 17 consists of an inside face 24, an outside face 61, and sides 25 and 26. The channel 16 and the top cap 17 may be produced in standard lengths, which include, but are not limited to 10 feet. Nevertheless, the length may be special ordered to fit building requirements. There are several methods in which to manufacture the channel 16 and the top cap 17. Typically, the channel 16 and the top cap 17 come in a steel roll which has been ordered in a predetermined width. The roll is fed into a roll machine and bent into the desired shape forming the channel 16 and the top cap 17. The channel 16 and top cap 17 are then fed into another machine that will cut the channel 16 and top cap 17 into the desired lengths. Alternately, the channel 16 and the top cap 17 can be cut to a predetermined size and then roll formed or stamped. Often in the construction process the length of the channel 16 and the top cap 17 will need to change in order to meet specific job requirements. For example, if a wall is to be erected which is 32 feet in length, and the channels 16 and the top caps 17 are shipped to the site in 10 foot lengths or longer, the channels 16 and the top caps 17 can be cut on-site to meet this job requirement. In assembling space-frame 50, the channel 16 is laid out in a predetermined length with one of the sides 21 or 23 facing down so that the space-frame 50 is assembled lying down. In the alternative, the channel 16 can be laid out in a predetermined length with the top face 22 facing up so that the space-frame 50 is assembled standing up. In this manner, the top face 22 provides a base and the sides 21 and 23 will provide mounting points for the stud 10. In the same way, and when a top cap is desired, the inside face 24, and sides 25 and 26 of the top cap 17 provide mounting points for the stud 10.
The curved edge 11 increases the amount of steel at the end of the side 12. Similarly, the curved edge 75 increases the amount of steel at the end of the side 70. Increasing the amount of steel at the end of the side 12 and the side 70 increases the stiffness and strength of the stud 10 and prevents flexing and twisting in the stud 10.
The stud 10 includes the recess 58 in the side 12 and the recess 71 in the side 70 to serve as connection points for the channel 16, the block 13, and, if desired, the top cap 17. The recesses 58 and 71 further serve to increase the stiffness and strength of the stud 10, thereby preventing flexing and twisting in the stud 10.
As with the channel 16 and the top cap 17, the stud 10 may come in a steel roll that has been ordered in a predetermined width. The roll is fed into a roll machine and bent into the desired shape, forming the stud 10. The stud 10 will then be fed into another machine that will cut the stud 10 into the desired lengths. Alternately, the stud 10 can be cut to a predetermined size and then roll formed or stamped. It should be understood that the roll machine or stamp machine includes members that form the curved edges 11 and 75 and the recesses 58 and 71 when the stud 10 is fed into the roll machine or stamp machine.
The desired length of the stud 10 will be determined by the desired size of the space-frame 50. For example, if the space-frame 50 is used for a wall, then the length of the studs 10 will depend on the height of the wall. In residential construction, common wall heights are typically 8 ft, 9 ft, or 10 ft lengths. Therefore, the length of the studs 10 will typically come from the factory in 8 ft, 9 ft, or 10 ft lengths. Nevertheless, the lengths of the studs 10 can be varied, either by cutting the studs 10 on site or by ordering the studs 10 from the factory in a custom length. This distinguishes the present invention from wood, which only comes in standard lengths, requiring the cutting of wood boards on site if a custom length is desired.
The block 13 includes a cross-member 67, sides 69 and 80, and tabs 15, 72, 73 74. In addition, the side 69 terminates in a curved edge 14 and the side 80 terminates in a curved edge 76. The tabs 15, 72, 73 and 74 include a respective recess 84, 82, 81, and 83 and respective indention 77, 17, 78, and 79.
The curved edge 14 increases the amount of steel at the end of the side 69. Similarly, the curved edge 76 increases the amount of steel at the end of the side 80. Increasing the amount of steel at the edge of the side 69 and the side 80 of the block 13 increases the strength of the block 13, which prevents flexing and twisting in the block 13.
The tabs 15, 72, 73, and 74 are attachment points for the block 13 to a stud 10. The indentions 77, 17, 78, and 79 are guides for a fastener such as a metal screw to be inserted into the tabs 15, 72, 73, and 74. The tabs 15, 72, 73, and 74 include a respective recess 84, 82, 81, and 83 to allow the tabs 15, 72, 73, and 74 to fit inside either the recess 58 or the recess 71 of the stud 10. This allows a fastener to fit completely inside the recess 58 or the recess 71 of the stud 10 and beneath the outer edge of either the side 12 or the side 70. As previously described, this provides a flush mounting surface and prevents the fastener from protruding into dry wall or any other flat fascia or facade. Moreover, the attachment of the tabs 15, 72, 73, and 74 at a respective side 12 or side 70 secures the block 13 across the stud 10 and locks the block 13 to the sides 12 and 70, thereby providing lateral stabilization between the stud 10 and a second stud 10 adjacent thereto.
The block 13 may be formed in a manner similar to the stud 10. The block 13 may come in a steel roll that has been ordered in a predetermined width. The roll is then fed into a punch press machine that forms the basic shape of the block 13 and cuts the block into the desired length. Alternately, the block 13 can be cut to a predetermined size and then roll formed or stamped. The block 13 will require an additional step in order to be formed. After the block 13 has been cut into the desired lengths, the block 13 will then be fed into another machine which will cut and form the tabs 15, 72, 73, and 74, and press the recesses 81, 82, 83 and 84, and indentions 17, 77, 78, and 79 into the block 13. The length of the block 13 is dependent upon the desired spacing of the studs 10. By way of illustration, the stud 10 spacing may be the standard 16 inch or 24 inch on center which makes the block 13 either 17¼ or 25¼ inches in overall length. Those of ordinary skill in the art will recognize the length may adjust as necessary to meet building requirements.
If the space-frame 50 is assembled lying down, the stud 10 is placed in the channel 16, between the sides 21 and 23, and a fastener such as a metal screw is inserted into either side 21 or side 23 of the channel 16 anchoring the stud 10 to channel 16, this is illustrated in
Referring to
The modularity of the present invention allows for predetermined spacing of studs 10 using the block 13. This is opposite of wood in that wood boards must be cut on site to meet the blocking needs adding to labor costs. Moreover, the block 13 laterally stabilizes the studs 10 and thus the space-frame 50, which prevents twisting and failing of the space-frame 50 when loaded axially. While the blocks 13 permit predetermined stud 10 spacing such that a space-frame 50 may be easily laid out and constructed, the blocks 13 may be cut on-site to accommodate stud 10 spacing necessary to conform a space-frame 50 into the length desired for the structure. At this point the space-frame 50 will consist of a channel 16, a stud 10, and the block 13. A second stud 10 will be added to the channel 16, and the block 13. The block 13 provides predetermined spacing for the second stud 10 allowing easy placement of the second stud 10. The second stud 10 is placed in the channel 16 between the sides 21 and 23 of the channel 16 and between the tabs 72 and 15. Referring to
If so desired a top cap 17 may be added to the space-frame 50. Alternatively, a block 13 may be added in place of a top cap 17. The tops of the studs 10 are inserted into the top cap 17 between the sides 25 and 26 of the top cap 17. A fastener such as a metal screw is inserted through the side 25 or 26 of the top cap 17 and the side 12 of the stud 10. As with the channel 16, when the fastener is inserted through either the side 25 or 26 of the top cap 17 and into the stud 10 at the recess 58, the side 25 or the side 26 deforms and presses into the recess 58 of the side 12. As previously described, this provides a flush mounting surface and prevents the fastener from protruding into dry wall or any other flat fascia or facade. If a block 13 is used in place of a top cap 17 it will be mounted to the stud 10 as describe above.
At this point the space-frame 50 is comprised of a channel 16, two studs 10, a block 13, and a top cap 17 or a block 13 in place of the top cap 17. If this constitutes a completed side of the space-frame 50, the space-frame 50 is turned over so that fasteners may be inserted in the opposite side of the space-frame 50 in the same manner as previously described. In most instances, however, a space-frame 50 will include multiple studs 10 within a channel 16 and multiple blocks 13 to create a larger structure. It should be recognized that more than one space-frame 50 may be connected together. If this configuration is desired, then fasteners will be inserted into the studs 10 located at one end of the space-frame 50; this will lock the two studs 10 together and ultimately lock the two space-frames 50 together.
If more strength is required, then two studs 10 can be used in space-frame 50 as illustrated in
The modularity of the present invention allows for multiple configurations and great flexibility in meeting particular job requirements. Illustratively,
The present invention is useful in building all types of frames including roof frames as illustrated in
