Support and skirting system for factory built structures
A system for shirting and securely supporting a factory built building against lateral and vertical loads. Lateral loads experienced by the building can include those created by seismic activities, heavy winds, heavy snow and back-filling earth around the building. The system includes at least one footing, at least one support stand and at least one skirting panel. The footing contacts the ground and can be formed of a material such as concrete. The footing includes an elongated channel that securely receives a portion of the support stand and the skirting panel. The support stand includes a plurality of support members and a base. The support members that define the support stand each extend in a common vertical plane. The system allows the building to be easily and quickly assembled. The components are also aesthetically pleasing, while creating a protective and stable support system for the factory built building.
The present invention relates to factory built residential and commercial structures, and more particularly, to a system and its components for surrounding and securely supporting factory built residential and commercial buildings.
BACKGROUND OF THE INVENTIONFactory built residential and commercial buildings have become increasingly popular. As the cost of new construction rises, the relatively lower cost of factory built residential and commercial buildings has attracted many new buyers. Similarly, the design and use of these buildings has changed over the past years. These new designs and uses have made factory built buildings more aesthetically attractive to consumers. Factory built buildings are now widely used in place of traditionally-styled buildings including residential housing, office buildings, such as permanent and portable office buildings, classrooms and transportable hospitals.
As used herein, the phrase “factory built buildings” includes, but is not limited to, permanent “traditionally styled” manufactured structures such as those mentioned above and other manufactured buildings or manufactured homes where the manufactured structure is trucked to the building site on flatbed trailers or the like. The phrase “factory built buildings” also encompasses structures that can be readily moved including transportable office buildings, hospitals and residential housing commonly referred to as “trailer homes.” Furthermore, modular structures including modular office buildings and modular homes are also encompassed by the term “factory built buildings” as sections of these structures are built at an offsite location, such as a factory, and then transported to a site for assembly as a unitary structure.
Factory built buildings are traditionally built upon a frame containing two or more longitudinal members and/or several transverse beams that support the floors of the building. Support systems for these factory built buildings typically include concrete blocks or a plurality of support stands placed under the frame for supporting it and securing it to a type of foundation. Skirting, extending from the factory built building's rim joist to a point within the ground, is commonly used to secure and hide the foundation support system and provide a more aesthetic appearance. However, conventional foundation support and skirting systems may not provide adequate support to the factory built building in response to the lateral forces created by heavy winds, seismic activities or heavy snow. Unfortunately, those systems that may provide adequate support can be costly to produce and install. Additionally, these systems may be aesthetically unattractive. Further, when a cement foundation/footing is poured for aesthetic purposes, the poured concrete must be allowed to set at the job site, thereby delaying the assembly of the building at the job site.
It is also difficult to back-fill soil against conventional skirting and supporting systems for factory built buildings. It is the ability to back-fill dirt and soil against the skirting that helps to give a factory built building the appearance of a site built home. However, if the support assembly of the skirting and supporting system does not provide sufficient structural integrity to the skirting so that the skirting can withstand significant lateral loads, the skirting may fail during the back-filling process. More seriously, if either the skirting or support assembly fails, the factory built building may move during the back-filling process and/or support stands of the support assembly attached to the factory built building may begin to bend and fail before the factory built building is ever occupied. This would present significant dangers to the occupants of the factory built building.
There is a decided need in the art for a skirting and supporting system useable with factory built buildings to effectively anchor the building during seismic activities, heavy winds, heavy snows and back-filling. The skirting and supporting system would provide support for the factory built building while presenting an aesthetically appealing appearance.
SUMMARY OF THE INVENTIONAspects of the present invention relate to a system and its components for skirting and securely supporting a factory built building against lateral and vertical loads. Lateral loads experienced by the building can include those created by seismic activities, heavy winds, heavy snow and back-filling earth around the building. The components of the system allow the building to be easily and quickly assembled. The components are also aesthetically pleasing, while creating a protective and stable support system for the factory built building.
In an embodiment, the system for supporting and skirting a factory built building includes a footing having an elongated channel extending in a direction that is substantially parallel to a longitudinal axis of said footing and a support assembly comprising a plurality of support members and a base. The base has a portion received within the channel of the footing. The system also includes a skirting panel positioned within the channel such that the portion of the base within the channel is positioned between the skirting panel and a sidewall of the channel. In at least one embodiment, the support assembly comprises a support stand including the support members. In these embodiments, the support members defining the support stand extend within a common vertical plane.
According to another aspect of the invention, the system for supporting a factory built building comprises a footing having an elongated channel extending in a direction that is substantially parallel to a longitudinal axis of the footing. In this embodiment, the system also includes a support assembly comprising a plurality of support members and a base having a portion received within the channel of the footing. This embodiment further includes a skirting panel positioned within the channel such that the portion of the base within the footing channel is positioned between the skirting panel and a sidewall of the channel.
BRIEF DESCRIPTION OF THE FIGURES
As shown in
The skirting and support system 10 comprises a perimeter support assembly 50 and a skirting assembly 300. The support assembly 50 includes at least one support stand 210 and at least one perimeter load bearing footing 100 as shown in
The number and/or size of support stands 210 and footings 100, as well as the linear feet of the skirting panels 310, can differ from building to building depending on the length of the building, weight of the building and/or the lateral loads that will be experienced by the building. For example, the greater the lateral forces that will be experienced by the building, the more support stands 210 and footings 100 that may be installed to support the base of the factory built building.
As shown in
The elongated channel 120 is spaced from the sloped sidewalls 112, 114 of the footing 100 such that the channel 120 is offset from the longitudinal center of the footing 100. As illustrated in
In
As shown in
The footings 100 can include one or more lengths of rebar 135. In an embodiment, the rebar 135 extends through the footing 100 in horizontal and/or vertical planes. The rebar 135 could take the form of individual lengths extending parallel or at an angle to the length of the footing 100 and channel 120. In an alternative embodiment, the rebar 135 forms a rectangular shape, a U-shaped or X-shaped orientation within the footing 100.
The footing 100 supports the support stand 210 that is securely connected to the factory built building and that assists in keeping the skirting panels 310 in their upright position as shown in
The support members 215 can be formed of angle steel or channel steel with the openings of the angle or channel steel opposing each other as shown in
An alternative embodiment of the support stand 210 is shown in
In any of the above-discussed embodiments, the support members 215 are welded to the base 220 and the bushing 230. However, other known ways for securing the support members 215, 216, 217, the support base 220 and the bushing 230 together as a support assembly 210 could also be used.
The bushing 230 is located at an upper, vertical end of the support stand 210. The bushing 230 receives a threaded rod 240 that can adjust the distance between the footing 100 and the frame of the factory built building. The rod 240 has an upper end 241 that carries a seating device 242 (
The threaded rod 240 includes an engagement member 247, such as a nut, that can be engaged in order to move the rod 240 relative to the bushing 230. Other known members that can be engaged and moved in order to rotate the threaded rod 240 can also be used. In the illustrated embodiment, as the movement of the engagement member 247 causes the threaded rod 240 to rotate relative to the support stand 210 and the bushing 230, the height of the supported building is leveled so that the base of the building occupies the same horizontal plane. In one embodiment, the threaded rod 240 has a total moveable distance of about 2.5 inches. However, the threaded rod 240 can have a total moveable distance that is greater or less than 2.5 inches. Also, the rod 240 can occupy an infinite number of positions along its total moveable length.

In yet another embodiment, illustrated in
The skirting panels 310 shown in
The precast cement skirting panels 310 can be easily painted or otherwise decorated to change their outwardly visible aesthetic appearance. Additionally, the precast cement skirting panels 310 provide protection to the support assembly 50 and the factory built building by resisting rotting and damage experienced by conventional skirting panels at the hands of insects and/or vermin. When positioned within the channel 120 of the footing 100 and against the support stand 210, thermal retention properties of the skirting panels 310 provide temperature insulation to the supporting assembly 50 and the factory built building. The skirting panels 210 also protect the support assembly 50 and the underside of the factory built building from heat and fire damage that could result from fires in the vicinity of the exterior of the factory built building.
As illustrated in
In another aspect of the present invention, the support system 10 can be secured to the factory built building and function as a tie-down system. By securely attaching the support system 10 to the factory built building, the entire weight of the support system 10 is added to the weight of the factory built building. As a result, the factory built building's resistance to damage from high winds is increased.
In this embodiment, the support system 10 is attached to the factory built building when the seating device 242 is securely attached to the building at the rim joist or other known attachment point; the support members 215 holding the seating device 242 are secured to the base 220; and the base 220 is secured to the footing 100 either by friction or a connecting member such as a bolt, pin or screw. The seating device 242 can be secured to the support members 215 by placing a threaded engagement/holding member 247 on both sides of the bushing 230. In an embodiment, the lower engagement/holding member 247 is positioned on the bottom of the threaded rod 240 and tightened upward toward the supported building after the height and support of the stand 210 are set by proper adjustment of the engagement/holding member 247 above the bushing 230.
In any of the above embodiments, the support stands 210 can be secured to their respective footing 100 by positioning two or more elongated members, such as bolts, rods or pins, through holes in the portion of the base 220 overlapping a portion of the footing 100 and threaded inserts imbedded in the load-bearing surface of the footing 100 during footing construction.
Effectively attaching the footings 100, support stands 210 and skirting panels 300 to the building adds the following to the effective weight of the structure: (1) The entire weight of the system 10 (since the footing 100 holds the weight of the concrete skirting panels 300 and the support stands 210); (2) the weight equivalent of the force necessary to pull-out the securing rods from within the imbedded inserts in the footings; and (3) the weight of the back-filled material that extends over the footings 100.
Numerous characteristics, advantages and embodiments of the invention have been described in detail in the foregoing description with reference to the accompanying drawings. However, the disclosure is illustrative only and the invention is not limited to the illustrated embodiments. It will be apparent to persons ordinarily skilled in the art that modifications may be made thereof within the scope of the invention, which scope is to be accorded the broadest interpretation of the claims such as to encompass all equivalents, devices, and methods. Therefore, various changes and modifications may be effected therein by one skilled in the art without departing from the scope or spirit of the invention. For example, the footing 100 may be secured in position with the previously mentioned securing rods, or by using a known geogrid-type material. Additionally, the panels 310 could be positioned within the channels 120 of the footings 100 without the support stand 210. In such an embodiment, an alternative support device, such as a metal plate, angle steel or wedge may be positioned within the channel 120 behind the panels 310 to support the panels 310, and in some embodiments, also the building, when in their vertical positions.
