Abstract
Abstract A sealed connecting construction for membrane segments covering a building framework of rigid trusses. The side edges of adjoining segments have cables secured thereto and the cables are detachably connected by one or more chain links to clips overlying the outer chord of the truss. The segments are tensioned by catenary cables secured to the bottom edges of the segments and extending between the truss members. The connection is weather-sealed by an overlying membrane strip or strips having tensioning cables along the outer edges anchored to the foundation base.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
100 words
In a sealed joint structure connecting adjoining membrane segments, an upright truss member forming part of a supporting framework and having an outer chord, attaching clips mounted at intervals along the chord, and link means detachably connecting the side edges of two adjoining segments to said clips under tension, catenary hold-down cables extending along the bottom edges of said segments and having their ends anchored to said framework, said link means comprising links adapted to detachably engage with like links for permitting the use of additional links facilitating progressively connecting the adjoining segments to the truss chord under decreased tension.
Claim 2
Dependent Claim
100 words
In a sealed joint structure connecting adjoining membrane segments, an upright truss member forming part of a supporting framework and having an outer chord, attaching clips mounted at intervals along the chord, and link means detachably connecting the side edges of two adjoining segments to said clips under tension, catenary hold-down cables extending along the bottom edges of said segments and having their ends anchored to said framework, said link means comprising links adapted to detachably engage with like links for permitting the use of additional links facilitating progressively connecting the adjoining segments to the truss chord under decreased tension.
