Abstract
Abstract A building construction in which parallel sheets of impervious material are carried in laterally stressed relationship by bridging members of a resilient and imperforate construction. The joint between adjacent sheet material members and the bridging members is water tight in use when the entire structure is placed in tension.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
67 words
In a building structure, the provision of a covering member comprising, in combination, a plurality of sheet members having coupling means formed on two opposing edges of each sheet, a bridging member receiving the coupling means of two adjacent sheet members, and tensioning means connected to the outside edges of the outermost sheet members and tensioning the sheet members and the bridging member as a unitary structure.
Claim 2
Dependent Claim
67 words
In a building structure, the provision of a covering member comprising, in combination, a plurality of sheet members having coupling means formed on two opposing edges of each sheet, a bridging member receiving the coupling means of two adjacent sheet members, and tensioning means connected to the outside edges of the outermost sheet members and tensioning the sheet members and the bridging member as a unitary structure.
Claim 3
Dependent Claim
53 words
The building structure of claim 1 wherein the bridging member is a tube which has been slit longitudinally to present continuous jaw portions for coaction with the coupling means on the edges of the sheet members, whereby the jaw portions of the tube react resiliently to variations in tension within the covering member.
Claim 4
Dependent Claim
44 words
The building structure of claim 1 wherein the bridging member is supported on a frame, plate members mounted on the frame, said plate members being shaped to embrace said bridging member and retain the same in a selected position without perforating said bridging member.
Claim 5
Dependent Claim
20 words
The building structure of claim 1 wherein the bridging member is supported by hangers projecting upwardly from the bridging member.
