Abstract
Abstract A wall construction for a spherical structure which includes elongated frame members subassembled at their ends by first apex connecting elements to form triangular frames. The subassembled frames are covered by triangular panels and interconnected to form the spherical structure by using second vertex connecting elements against which the first apex connecting elements are affixed.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
179 words
A wall construction for a spherical wall structure, comprising in combination: elongated frame members; first connecting elements, each of which is provided with angularly disposed legs joined by a nose section; first means for attaching said frame members to the legs of said first connecting elements to form triangular frames wherein the legs and apexes of said frames are defined respectively by said frame members and said first connecting elements; triangular panel members overlying said frames, said panel members having peripheral flaps overlapping the exterior sides of said frame members; second connecting elements, each having a truncated conical wall; and second means for attaching the nose sections of said first connecting elements to the walls of said second connecting elements, the positions of said first connecting elements when thus attached being such that the peripheral flaps of adjacent panel members will abut along planes extending radially from the centers of said second connecting elements with the ends of said flaps being cut away to thereby permit the apexes of said triangular panel members to overlie said second connecting elements.
Claim 2
Dependent Claim
179 words
A wall construction for a spherical wall structure, comprising in combination: elongated frame members; first connecting elements, each of which is provided with angularly disposed legs joined by a nose section; first means for attaching said frame members to the legs of said first connecting elements to form triangular frames wherein the legs and apexes of said frames are defined respectively by said frame members and said first connecting elements; triangular panel members overlying said frames, said panel members having peripheral flaps overlapping the exterior sides of said frame members; second connecting elements, each having a truncated conical wall; and second means for attaching the nose sections of said first connecting elements to the walls of said second connecting elements, the positions of said first connecting elements when thus attached being such that the peripheral flaps of adjacent panel members will abut along planes extending radially from the centers of said second connecting elements with the ends of said flaps being cut away to thereby permit the apexes of said triangular panel members to overlie said second connecting elements.
Claim 3
Dependent Claim
29 words
The wall construction as claimed in claim 1 wherein said first means is comprised of bolts, the axes of which converge at the centers of said truncated conical walls.
Claim 4
Dependent Claim
39 words
The wall construction as claimed in claim 1 wherein the angularly disposed legs of said first connecting elements are provided with laterally extending bosses which are received in apertures in the elongated frame members attached to the said legs.
Claim 5
Dependent Claim
43 words
The wall construction as claimed in claim 1 wherein each of said second connecting elements is further characterized by a reinforcing plate extending across the upper end of said truncated conical wall in a plane perpendicular to the central axis of said wall.
Claim 6
Dependent Claim
29 words
The wall construction as claimed in claim 1 further characterized by fasteners extending laterally through adjacent elongated frame members and the legs of the first connecting elements attached thereto.
