Patent number: 6318044Abstract: According to existing methods of frame building construction, a concrete foundation is formed on which wooden floor joists are laid. Walls are constructed on the foundation and floor using wooden wall studs, and a roof is constructed on the walls using wooden rafters, beams and trusses. These methods require skilled carpenters and high quality wood materials, both of which are increasingly expensive. There is therefore a need for a system for framing houses or other buildings which uses prefabricated steel framing and which is quick and easy to construct. The invention provides a prefabricated system for framing a complete building on a foundation. Folding telescopic framing units are used for vertical partitions and horizontal floor panels.Type: GrantFiled: October 13, 1999Date of Patent: November 20, 2001Inventor: Ronald W. Campbell

Patent number: 6298617Abstract: A prefabricated structural system uses wall panels having a combination of cold rolled light gauge sheet metal and hot rolled tubular steel. Panels are stacked one on top of each other to form vertical wall assemblies and may be welded directly with their top and bottom members or include intermediate shear connectors. Shear resistance or resistance to lateral forces is provided by a single continuous metal sheet either flat or corrugated (a deck-type sheet) fastened to the steel studs or alternatively diagonal or V-shaped bracing. Connectors between the wall panels provide a gap for a continuous concrete floor. Vertical wall assemblies can be constructed with individual wall panels either on-site or off-site and then tilted up to form a completed building. The vertical assemblies are then connected together by connector beams or ladder frames.Type: GrantFiled: July 9, 1998Date of Patent: October 9, 2001Inventor: Jorge de Quesada

Patent number: 6260318Abstract: The present invention relates to wall construction, and more particularly to a new and improved means for bracing parallel studs, draft dampening between parallel studs within interior wall structures, and anchoring hand rails and grab bars to walls using a single unitary device. A one piece elongated metal plate is inserted transversely between parallel metal studs to provide the largest percentage of closure between metal studs thereby forming a fire stop (also known as a draft dampener) within the completed wall assembly and simultaneously providing a metal backing for the installation of handrails and grab bars in conformity with requirement of the Americans with Disabilities Act and Uniform Building Code requirements. The insertion of this one piece elongated plate further serves to reinforce the strength of metal studs permitting the use of lighter gauge metal studs resulting in construction cost savings.Type: GrantFiled: January 12, 2000Date of Patent: July 17, 2001Inventor: Thomas Ross Herren
