ABSTRACT:
The present invention is directed to a high-rise building system using steel wall panels and, more particularly, a combination of light gauge and heavier gauge hot rolled steel members arranged to resist both vertical and lateral forces.
BACKGROUND OF THE INVENTION
As illustrated in application Ser. No. 684,461, filed Jul. 19, 1996, in the name of the present inventor, for use in a multi-story building, lightweight prefabricated wall panels may be used. The panels include several spaced vertical cold rolled light gauge steel metal studs extending between top and bottom channels in which they are retained. A pair of hot rolled steel members are fixed vertically at the left and right ends of the panel. In addition, to resist shear diagonal bracing plates are specifically shown.
In order to facilitate building with metal beams, Goodson U.S. Pat. No. 4,514,950 discloses a framing technique for steel construction where component parts are pre-assembled and then joined at the job site.
There is still a need to provide for steel designed buildings and construction techniques which are compatible with existing standard design techniques such as supporting dry walls, etc., and which provide for easy fabrication.
OBJECTS AND SUMMARY OF THE INVENTION
It is therefore an object of the invention to provide an improved high-rise building system using steel wall panels.
In accordance with one aspect of the invention, there is provided a lightweight, prefabricated wall panel having left and right ends which is able to resist both vertical and lateral forces for use as a wall in a multi-story building of three or more stories comprising a plurality of spaced vertical cold rolled light gauge sheet metal studs extending between top and bottom steel members to which they are connected. Bracing means are connected to the studs and members for providing resistance to lateral forces, and a pair of hot rolled steel members are affixed vertically to the left and right ends of said panel including the top and bottom steel members and the bracing means. The bracing means include a single continuous metal sheet extending over substantially all of the studs of the wall panel and include means for fastening the metal sheet to the studs and steel members.
From another aspect, there is provided a lightweight, prefabricated wall panel which is both load bearing and shear resistant which may be stacked on top of one another for use as a wall in a multi-story building. Each of the panels have a frame consisting essentially of steel structural members including vertical members and top and bottom steel members which are formed of both cold rolled and hot rolled steel including means for vertically stacking and interlocking the panels. The cold rolled steel provides lightweight and the hot rolled steel provides for enhanced resistance to vertical forces. Means for stacking and interlocking include a plurality of discrete steel connectors with the top being welded to one of the top or bottom steel members and with the bottom being welded to the adjacent vertically stacked panel whereby enhanced resistance to shear is provided.
From another aspect, there is provided a prefabricated vertical frame assembly, which may be used as a portion of a wall in a multi-story building comprising a plurality of vertically stacked wall panels consisting essentially of tubular hot rolled steel structural members having a top and a bottom steel members, vertical side members and bracing means to resist lateral forces, the wall panels forming a unitary vertical assembly by the respective top and bottom steel members being fastened together.
As a modification of the foregoing, there is provided a prefabricated vertical frame assembly which may be used as a portion of a wall in a multi-story building comprising a plurality of vertically stacked wall panels consisting essentially of tubular hot rolled steel structural members including a horizontal steel member and at least one diagonal bracing member for resisting vertical and lateral forces. The wall panels form a unitary vertical frame by the horizontal steel members and bracing members being fastened to a pair of vertical left and right hot rolled steel side members, such side members having a continuous uninterrupted length equal to the plurality of stacked panels.
