Abstract
Abstract In a building construction having adjacent wall panel sections which are joined together at an exterior angle exceeding 180 degrees, an improved means is provided for supporting and joining the wall sections. A metallic channel member forms a portion of the joining edge of each wall section. Each channel member has one side wall which is bent inwardly towards its base section, and this inwardly bent side wall is secured underneath the exterior panel member so that the base section of the channel member in cooperation with the joining edge of the exterior panel member forms a substantially continuous joining surface.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
202 words
A frame for a flat triangular wall section of a geodesic dome structure in which (X+180) degrees is the exterior angle at which adjacent wall sections are joined together, the value of X being greater than zero but small compared to 90, comprising, in combination: three generally channel-shaped metal frame members, each having a flat central base section, a first flat side wall inclined at an angle of (90-(X/2)° to said base section, and a second flat side wall inclined at an angle of (90+(X/2)° to said base section; each of said side walls being curled in towards said base section; all three of said first flat side walls being disposed in a common plane, and each end of each of said frame members being cut perpendicular to said plane and at an acute angle relative to the adjacent end of the associated base section so that the adjacent ends of said frame members are in mating engagement; and the adjoining ends of said frame members being fastened together; whereby an exterior panel member may be supported upon and fastened to said first side walls and an interior finish panel member may be supported upon and fastened to said second side walls.

Claim 3
Dependent Claim
32 words
A triangular wall section including the frame of claim 1, and a triangular exterior panel member supported upon and fastened to said first side walls of all three of said frame members.
