Abstract
Abstract A structural module comprising a pair of parallel arcuate beams each having a side flange and a top flange, and a corrugated facing sheet marginally secured to the top flanges of the beams, the ends of the sheet being bent downwardly to form connecting flanges. Two or more modules may be interconnected at their adjoining connecting flanges as well as by coupling plates straddling the modules at their juncture and attached to the side flanges thereof. Each module constitutes a segment of a circular cylinder so that by combining such segments, one may erect caves, enclosures, dividers and other useful structures.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
162 words
A structure formed by a plurality of structural modules, each structural module constituting a segment of a circular cylinder and comprising a pair of parallel beams having an arcuate formation, each beam having a side flange and a top flange, a curved, generally rectangular sheet whose long sides are marginally secured to the top flanges of said beams to provide the only connection therebetween and to define a segment therewith, the ends of said sheet being bent downwardly in the free space between said beams to provide connecting flanges, said sheet being transversely corrugated to define alternate vaults and strips which lie in parallel relAtion to said flanges, said strips being secured at their ends to the top flanges of the parallel beams, said vaults having large openings therein to provide transparency to the module whereby like modules may be interconencted at adjoining connecting flanges, and coupling plates straddling the junction of two adjoining modules and attached to the side flanges thereof.
Claim 2
Dependent Claim
