TECHNICAL FIELD

This specification generally relates to expandable building systems and more particularly to removable and re-attachable wall systems for modular structure construction that permits horizontal expansion.

BACKGROUND

In the design and construction of structures, such as industrial warehouses, commercial buildings, and residential homes the builders and designers focus on the identified needs of the occupants and design and build a structure to meet their needs. While this type of design affords the occupants a structure that meets their currently identified requirements, overtime, the needs of the occupants change and the original design of the structures become obsolete.

With businesses and personal structures, it is often difficult to accurately plan and project for the future needs. Underbuilding to meet current financial needs of the occupants oftentimes results in the occupants requiring to move and obtain additional or new structures, while overbuilding can lead to increased costs of up keeping a facility and the possibility that the needs of the occupant will never expend to fully utilize the space. Thus, the current building methods involve a substantial amount of speculation and are often overbuilt for the current needs of the occupants.

When the occupants eventually outgrow their current structures, they oftentimes are required to look for additional buildings or structures. The process of purchasing additional real estate can be time consuming, difficult, and expensive depending on the market. For example, when a family “outgrows” a residential structure, they move to a different home with more square footage or a home with additional bedrooms. The moving process can be quite stressful, time intensive, and expensive. To prevent moving, some families add onto their existing home by adding an addition. Adding an addition onto an existing house is not easy; it's time consuming and costs the homeowner a significant sum of money.

Making an addition onto one's home is difficult, time intensive, and costly. This process is challenging because homes are not designed to be expanded on when initially constructed. Without knowing the structural capacity of the walls, the utilities located inside the walls, and without having a way to disassemble the walls without compromising the integrity of materials, adding onto one's home in the front, back, or side becomes a messy, burdensome process. Designing a residential structure with the intent of expanding horizontally can eliminate many of these steps, making the addition process much simpler.

Moreover, designing a dwelling unit using modular construction can reduce onsite construction time and costs and ensure better quality control in the building process. In addition, when using modular building techniques, the modular structures can easily and cost effectively be modified to meet the owners or occupants changing needs.

SUMMARY

This specification describes horizontally expandable building structures, for example, residential dwellings.

In one example, the present disclosure provides for the horizontal expansion of a residential dwelling by way of an expandable building system, comprised of a removable façade system, removable patch panels, and a quick connect expansion system. The expandability is achieved by building the original dwelling in a way that allows for specific walls to be removed without damage. Each of the aspects disclosed may have different means to achieve the same result of adding onto an existing dwelling without demolishing existing walls and reusing materials. The additions are made by attaching the new wall panels to the existing dwelling using either a compatible bracket or through the custom design of a structural insulated panel. In either case, a synthetic fabric weather barrier may be sandwiched between the existing dwelling wall and the new panel, then attached using bolts or other suitable means, described herein. This composition allows for a weather barrier to be continuous from the original module throughout the new additions.

In one example, a residential dwelling comprises a removable wall structure, or patch panels, that permits an addition to be added onto and additional structural unit. This expandability is achieved through a modular removable wall system that can be attached, removed, and reattached to the structure. The removable wall system is removable without compromising the structural capacity or performance and allows for the structural integrity of the structural unit to be maintained during the expansion process. The removable wall assembly may comprise additional wall panels, weather barrier, fascia, and patch panels which can be removed and reattached to the dwelling unit during a horizontal expansion. Once the additional wall panels are attached to the original dwelling, the insulation, weather barrier, fascia, and patch panels from the original dwelling's expandable wall structure are re-attached to the wall structure of the horizontal addition through the removable wall attachment system.

DETAILED DESCRIPTION

This specification is generally directed to expandable building systems, and more specifically, removable wall systems for use with modular building structures. However, they are not limited to such extemporary environments.

Generally speaking, numerous aspects described throughout the specification can be used in the construction of modular structures, prefabricated structures, as well as site-built structures. The removable wall assembly can allow modular structures to grow and expand as well as contrast as the needs of the building owners/occupants change. In one aspect, the removable wall assembly may permit the expansion of a modular residential structure its current footprint to a larger horizontal footprint, for example a rear or side addition that permits additional square footage to be added to the residential structure. In addition, the removable wall assembly may permit a modular residential structure to be contracted and an addition removed, for example when a family is looking to downsize after the children have left the home.

In other aspects, the removable wall assembly may allow for the replacement of exterior walls on structures designed as permanent buildings. In one aspect, the removable wall assembly may allow a building owner to easily replace the wall structures of a building to update the structural aspects as well as the visual aspect of a building structure. For example, the removable wall assembly may allow for ease of replacing a building with a vinyl siding with one of a wooded siding, a siding of a different color, or another type of exterior appearance, such as brick, or stucco. The ease of removal and replacement with the removable wall assembly can reduce labor costs and replacement wall assemblies can be constructed offsite and shipped to the location of the building which can reduce the time and labor costs associated with replacing a roof structure. Additionally, the removable wall assembly also may facilitate the easy removal and replacement of walls as technology improves and more efficient building materials are produced, such as increased thermal resistivity materials to allow a structure to be more energy efficient or technological upgrades, such as smart panels having built-in electronic features.

FIGS. 1A-K illustrate the process of removing a removable wall assembly, adding an additional wall panels and horizontal square footage onto an original residential dwelling, and reattaching the removable wall assembly. Referring to FIG. 1A, the original dwelling unit 100 is comprised of four vertical walls, a floor, a roof structure, and a removable wall assembly 110. The removable wall assembly comprises a removable façade 101. FIG. 1B illustrates the façade 101 of the removable wall assembly 110 being removed Arrow A from the original dwelling unit 100. The removable wall assembly 110 further comprises patch panels 103a-c. The patch panels 103a-c can be releasably attached to the original dwelling unit 100 through attachment assemblies 102. Each attachment assembly 102 can comprise an attachment mechanism that permits mechanical attachment of the patch panels 103a-c to the original dwelling unit 100. The attachment assembly 102 also may comprise a quick-connect bracket system that permits the efficient removal of the patch panels 103a-c from the original dwelling unit 100.

FIG. 1C shows the original dwelling unit 100 with the façade 101 having been completely removed. The original dwelling unit 100 is designed to permit the structure to remain structurally stable with the removal of the removable wall assembly 110, which can allow the internal furnishings and belongings of the occupant to remain in place during the horizontal expansion process.

Referring now to FIG. 1D, the patch panels 103a-c are shown in the process of being removed Arrow B. The attachment assemblies 102 have been disengaged and the patch panels 103a-c have been released from the original dwelling unit 100. With the removal of the patch panels 103a-c, the original dwelling unit 100 maintains its structural integrity and is now ready for horizontal building expansion.

FIG. 1E depicts the original dwelling unit 100 with the removable wall assembly 110 (façade 101, patch panels 103a-c, and attachment assemblies 102) removed. With the removable wall assembly 110 removed, opening 104 allows a horizontal addition to be connected to the original dwelling unit 100. FIG. 1F illustrates the horizontal building expansion with the addition of wall panels 105a-d and floor panels 106 being attached Arrow C. The wall panels 105a-d and the floor panels 106 can be attached to the original dwelling unit through an attachment assemblies, similar to attachment assembly 102. When multiple wall panels 105a-d are attached to the original dwelling unit 100, each wall panel 105a-d can be attached to longitudinal walls of the original dwelling unit 100 or to each subsequently added wall panel. Each of the wall panels 105a-d can have an attachment assembly that allows the wall panels 105a-d to be sequentially attached to the original dwelling unit 100 and to each added wall panel. By having a modular building structure with compatible attachment mechanisms, each additional wall panel or floor panel can easily be attached to the original dwelling until 100.

Referring to FIG. 1G, the wall panels 105a-d and floor panels 106 have been attached to the original dwelling unit 100. In addition, roof assembly 109 has been attached to the original dwelling unit 100 through the use of attachment assemblies that permitted the roof assembly 109 to be easily attached to the original dwelling unit 100. FIG. 1G further illustrates patch panels 103b, 103d, and 103e being attached Arrow F to the original dwelling unit 100. In various aspects, the original patch panels 103a-c may be attached to the original dwelling unit 100 through attachment assemblies 102. In addition, or in the alternative, additional patch panels 103d and 103e can be attached to the original dwelling unit 100. For example, a new patch panel 103d may be attached to the original dwelling unit 100 to add a door access to the original dwelling unit 100. In addition, patch panel 103e may be attached to the original dwelling unit 100 to add a window to the original dwelling unit 100. While the addition of doors and windows are shown during an expansion of the original dwelling unit 100, the patch panels 103d and 103e may be used to replace patch panels or wall panels of an original dwelling unit and allow the occupants to easily add additional windows or doors to the original dwelling unit 100 without the hassle experienced in such an addition in a non-modular structure.

FIG. 1H illustrates the original dwelling unit 100 with the patch panels 103b, 103d, and 103e attached, which comprise the structural components of the horizontal addition 107. Once the structural components of the horizontal addition 107 have been attached to the original dwelling unit 100, the façade 101 can be attached to the additional wall panels 105a-d and to the patch panels 103b, 103d, and 103e, as shown in FIG. 1I. Where the patch panels are not changed from the pre-expanded original dwelling unit 100, the original façade 101 can be reattached. If the occupant decides to add patch panels having additional features such as doors or windows, new or altered façades 101 can be reattached to the patch panels Arrow G. FIG. 1J illustrates the original dwelling unit 100 with the horizontal addition 107 and additional features of a door and window.

FIG. 1K illustrates one aspect of the attachment assemblies 102 that allow the horizontal addition 107 to be attached to the original dwelling unit 100. In one aspect, the attachment assembly 102 may comprise a bracket system that allows for the attachment of the components of the horizontal addition to be attached to the original dwelling unit 100.

Now referring to FIGS. 2A-2D, various aspects of a removable wall assembly 210a-b are shown. FIGS. 2A and 2B illustrate an elevation view of a removable wall assembly 210a having three patch panels 203a-c. The rear wall 218a has a framing 220a which defines an opening 204a. In FIG. 2A, the patch panels 203a-c are attached to the rear wall 218a within partial wall opening 204a. The framing 220 of rear wall 218a provides structural support and does not allow for the entire removal of the rear wall 218a. This orientation is shown in FIGS. 2A and 2B and may be used where the rear wall of a structure is required to be load barring to an extent. Thus, in the aspects show in FIGS. 2A and 2B, the framing 220 of the rear wall 218a allows for the removal of the patch panels 203a-c and the expansion of the original dwelling unit 200. FIG. 2B illustrates the framing 220 of the rear wall 218a of the original dwelling unit 200 with the patch panels 203a-c removed to allow for the horizontal expansion of the original dwelling unit 200.

FIGS. 2C and 2D illustrate and alternative aspect of a removable wall assembly 210b. The removable wall assembly of FIGS. 2C and 2D allows for the removal of the entire rear wall 218b of the original dwelling unit 200. The removable wall assembly 210b comprises patch panels 203d-f which comprise the entire rear wall 218b of the original dwelling unit 200. As seen in FIG. 2D, when the patch panels 203d-f are removed, the whole opening 204b stretches the entire rear wall 218b and allows for the original dwelling unit 200 to be expanded without having a partial wall opening 204a.

As see in FIGS. 3A and 3B, an attachment assembly 302 is shown. The attachment assembly 302 can be used to attach addition wall panels, for example wall panels 105a-d to the existing walls of an original dwelling unit 100. In addition, or in the alternative, similar attachment assemblies can be used to attaches floor panels 106 or roof assembly 109 to an original dwelling unit 100, as shown in FIGS. 1A-1K. FIG. 3A shows an attachment assembly 302 in a disassembled condition. The additional wall panels 305 or the walls of the original dwelling unit 300 can include façade 301, sheathing 315, insulation cavity 308 and threaded inserts 312. The additional wall panels 305, and or walls of the original dwelling 100, can comprise a panelized wall system using structural insulated panels (SIPs), traditional lumber framing, or metal studs. The sheathing 315 may provide the structural aspects of the panelized wall system. The additional wall panels 305, and or walls of the original dwelling 100 can be attached to one another through attachment assembly 302. In one aspect, shown in FIGS. 3A and 3B, the attachment assembly 302 can include bracket 322, fasteners 316, fastener openings 324, and weather barrier 304. The weather barriers 304 can be installed between the two conjoining panels during installation between the panels 305 and attachment assembly 302. The weather barriers 304 help ensure that a weather resistant seal is formed between the two wall panels 305. During assembly of the two wall panels to one another, the fasteners 316 releasably attach the wall panel 305, weather barrier 304 and bracket 322. The fasteners 316 can be threaded through the fastener opening 324, engage the weather barrier 304 and are then threaded into the threaded inserts 312. Each of the wall assemblies 305 can be attached to the attachment assembly through the same process and permits expansion of the original dwelling unit 300.

Now referring to FIGS. 4A and 4B, an alternative attachment assembly 402 is shown. FIG. 4A shows the attachment assembly 402 in a disassembled condition. The wall penalization system depicted in FIGS. 4A and 4B comprise a male-female connection. The wall panels 405 comprise sheathing 415 which provides structural component to the wall panel 405. The sheathing 415 of the female connection portion comprises an opening that allows a corresponding connection portion of the male connector of another wall panel to be inserted and attached. The female connection portion 426 comprises fastener openings 424 that allow fasteners 416 to be threadably passed, therethrough. The attachment assembly comprises two synthetic waterproof membrane weather barriers 404 that are affixed to the female connection portion 426 and the male connection portion 422. Each wall portion 405 comprises an insulation portion 408 on the interior of the sheathing 415 and a façade 401 on the outside of the wall panel 405. The fasteners 416 may be bolts or other types of fasteners. The two adjoining wall panels 405 are attached by inserting the male connection portion 426 of one wall assemble into the female portion 426 of an adjoining wall assembly with the weather barrier 404 therebetween. Once the wall panels are in a mating relationship with one another, the fasteners can be threadably attached through the fastener openings 422 in the female connection 426 and threadably attached to the threaded inserts of the male connection portion 422. FIG. 4B illustrates the attachment assembly shown in FIG. 4A in the attached condition.
