Description
BACKGROUND

Residential building has remained essentially unchanged for the last 300 years, with wood, wood byproducts and to a lesser extent masonry products providing the structure materials for the building.

Panelized building is not new, but has typically utilized wood and wood byproducts and utilized factory fabrication. The cost of shipping and no savings in materials has resulted in minimal to no economy to the end user.

There is a need for alternate materials to replace wood. Environmental concerns and increased regulation have made wood and consequently wood byproducts rise dramatically in cost.

Another need is for a complete system. Typically a panelized building is only panelized in it's walls and roofs and floors are a variation of wall panels. Timbrook patented a primitive drywall panel system approximately 14 years ago (U.S. Pat. No. 5,493,839 Feb. 27, 1996). It relied on complex equipment to fabricate the panels and was not conforming to requirements to obtain building permits.

There remains a need for a panelized system that imparts a substantial economy.

There remains a need for alternative materials to replace or substantially reduce the use of wood and wood byproducts in the construction process.

There remains a need for a complete panelized building system.

There remains a need for a panelized building system where the majority of components can be fabricated on site.

BRIEF SUMMARY OF INVENTION

This invention encompasses a total system with roof, floor, interior and utility panels and an exterior panel that includes integral framing for windows and doors. In addition, the exterior panel includes bi-directional studs for increased strength not only vertically but horizontally.

Finally, the panels are easily assembled on site resulting in a reduction of wood and wood bi-products of 91-95% and resultant savings of 35-45% on the entire building.

This invention simplifies fabrication, erection and complies with building code requirements.

The increased cost of wood and environmental concerns have made the decreased use of wood a priority for consumers, builders and governmental authorities.

As discussed above, there is a need to reduce or eliminate the need for wood in residential construction as well as commercial, institutional and industrial construction. There is a need for on site fabrication to reduce transportation costs and to reduce labor costs in construction.

This invention will allow for fabrication of panels of between 4 and 18 feet in height and of 4 and 20 feet in width and incorporate window and door frames utilizing drywall as it's primary component.

A preferred embodiment of this invention is directed to on site fabrication of the panels.

One embodiment is a building panel comprised of a first drywall sheet, a second drywall sheet, at least a plurality of drywall studs attached between the first drywall sheet and the second drywall sheet and where the studs separate the drywall sheets by at least 3 inches wherein the drywall studs attached between the first and second drywall sheets comprise drywall studs at least in part adhesively attached to the first and second drywall sheets.

One embodiment is a building panel comprised of first drywall sheets, a second drywall sheet, at least 3 studs separating first drywall sheet and the second drywall sheet and at least one drywall stud is substantially parallel with the other two drywall studs and wherein at least 3 drywall studs are attached to the first and second drywall sheet.

One embodiment is a building panel comprised of first drywall sheets, second drywall sheet, at least 1 drywall stud forms an angle of at least 40 degrees to the other 2 drywall studs.

One embodiment is a building panel comprised of first drywall sheets, a second drywall sheet, at least 1 drywall stud forms an angle of at least 80 degrees to the other 2 drywall studs,

One embodiment is a building panel comprised of first drywall sheets, a second drywall sheet, a plurality of drywall studs attached between the first drywall sheet and the second drywall sheet, a bottom plate between the first and second drywall sheets and attached to the first and second drywall sheets, a corner stud extending between the first drywall sheet and the second drywall sheet and attached to the first and second drywall sheets.
