Abstract
Abstract A hold-down system for a membrane (10) covering a rigid framework and having catenary cables (11 and 12) secured to the bottom edges of said membrane between bays, said system having a retainer sleeve (19) comprising spaced-apart plates (21) connected by inclined side bars (22) and a wedge-shaped keeper plate slidable therein to wedgably hold overlapping loops (11' and 12') of the end portions of two contiguous cables (11 and 12) and flexible linear means (16) detachably connecting said keeper plate to a foundation anchor (15).

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
63 words
A hold-down system for a tensioned membrane covering a rigid framework and having catenary cables secured to its lower edges between bays, comprising retainer means wedgably holding the end portions of two contiguous cables in overlapping loops, and flexible linear means detachably connected at one end to said retainer means and adapted at its other end for detachable connection to a foundation anchor.
Claim 2
Dependent Claim
63 words
A hold-down system for a tensioned membrane covering a rigid framework and having catenary cables secured to its lower edges between bays, comprising retainer means wedgably holding the end portions of two contiguous cables in overlapping loops, and flexible linear means detachably connected at one end to said retainer means and adapted at its other end for detachable connection to a foundation anchor.
Claim 3
Dependent Claim
28 words
A hold-down system as described in claim 1, wherein the retainer means comprises a retainer sleeve and a keeper slidable therein to wedgably engage said cable end portions.
Claim 4
Dependent Claim
18 words
A hold-down system as described in claim 2, wherein said linear means is detachably connected to said keeper.
Claim 5
Dependent Claim
33 words
A hold-down system as described in claim 3, wherein said retainer sleeve comprises two spaced-apart plates connected by inclined side bars, and said keeper comprises a flat plate having similarly inclined side edges.
Claim 6
Dependent Claim
25 words
A hold-down system as described in claim 4, wherein said retainer plates are spaced apart a distance substantially equal to the diameter of said cables.
Claim 7
Dependent Claim
53 words
A hold-down system as described in claim 5, wherein the side edges of said keeper plate when inserted in said retainer sleeve are spaced laterally from said side bars a distance of two cable diameters, so as to wedge the two cables in lateral side-by-side relation between the keeper and said side bars.
