Abstract

Abstract A prefabricated panel utilizing a lightweight metal frame fabricated from metal members having a web and two substantially parallel flanges which extend in opposite directions from the edges of the web. The facing is joined to said frame by means of joining means which extend from the back of said facing through holes in the flanges of the members of the frame.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 242 words
A prefabricated Panel which comprises: a. A frame for supporting facing in a prefabricated panel which comprises; substantially parallel longitudinal members, fixed at the ends by transverse end members attached to said longitudinal members and stiffened with cross braces attached to said longitudinal members, at least said longitudinal members, and transverse end members comprising metal members having a web with two substantially parallel flanges extending in opposite directions from said web and said flanges on at least one side of said longitudinal and transverse end members being in substantial planar alignment and at least said flanges on said longitudinal members in planar alignment with said flanges on said transverse end members having holes through which means for joining said supported facing to said frame can pass. b. one or more substantially flat rigid members which at least cover the frame and are adjacent to the flanges of the longitudinal and transverse end members which are in substantial planar alignment, said flat rigid members having holes in alignment with the holes in the flanges of the frame adjacent thereto, c. a stone facing member having an exposed front and a back, the back of said facing member being adjacent to said rigid member and having means extending from blind holes in the back of said facing member which pass through said holes in said rigid member and said frame to join said facing, said rigid member and said frame into a prefabricated panel.
Claim 2
Dependent Claim 242 words
A prefabricated Panel which comprises: a. A frame for supporting facing in a prefabricated panel which comprises; substantially parallel longitudinal members, fixed at the ends by transverse end members attached to said longitudinal members and stiffened with cross braces attached to said longitudinal members, at least said longitudinal members, and transverse end members comprising metal members having a web with two substantially parallel flanges extending in opposite directions from said web and said flanges on at least one side of said longitudinal and transverse end members being in substantial planar alignment and at least said flanges on said longitudinal members in planar alignment with said flanges on said transverse end members having holes through which means for joining said supported facing to said frame can pass. b. one or more substantially flat rigid members which at least cover the frame and are adjacent to the flanges of the longitudinal and transverse end members which are in substantial planar alignment, said flat rigid members having holes in alignment with the holes in the flanges of the frame adjacent thereto, c. a stone facing member having an exposed front and a back, the back of said facing member being adjacent to said rigid member and having means extending from blind holes in the back of said facing member which pass through said holes in said rigid member and said frame to join said facing, said rigid member and said frame into a prefabricated panel.
Claim 3
Dependent Claim 14 words
The prefabricated panel of claim 1 wherein said rigid member is asbestos cement board.
Claim 4
Dependent Claim 69 words
The prefabricated panel of claim 2 wherein said facing is selected from a group consisting of marble, granite, travattine, and fieldstone and wherein said means extending from the back of said facing are threaded studs anchored in blind holes in the back of said facing with an epoxy resin and said facing is joined to said frame by means of nuts which interact with the threads on said studs.
