Abstract
Abstract A freestanding structural wall panel comprising a plurality of elongated spaced apart wire assemblies comprising first and second elongated wire members each formed into a continuous generally triangular shape, a first longitudinal wire member coupled to the lower apices of the first and second triangular wire members such that the apices of one triangular wire member are staggered with respect to the apices of the other triangular member and the planes of the first and second continuous triangular members form an angle with each other and second and third longitudinal wire members coupled to the upper apices of the first and second triangular wire members respectively, a layer of concrete partially embedding the wire members, and a layer of polyurethane foam formed for insulation purposes on the concrete layer and partially embedding the wire members whereby ducts, pipes and wiring may be placed under the non-embedded portion of the wire members and wall board may be attached to the wire members.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
98 words
A truss structure comprising: a. first and second elongated wire members each formed into a continuous generally triangular shape, b. a first longitudinal wire member coupled to the lower apices of said first and second triangular wire members such that the apices of one triangular wire member are staggered with respect to the apices of the other triangular member and the planes of said first and second continuous triangular members form an angle with each other, and c. second and third longitudinal wire members coupled to the upper apices of said first and second triangular wire members respectively.
Claim 2
Dependent Claim
98 words
A truss structure comprising: a. first and second elongated wire members each formed into a continuous generally triangular shape, b. a first longitudinal wire member coupled to the lower apices of said first and second triangular wire members such that the apices of one triangular wire member are staggered with respect to the apices of the other triangular member and the planes of said first and second continuous triangular members form an angle with each other, and c. second and third longitudinal wire members coupled to the upper apices of said first and second triangular wire members respectively.
Claim 3
Dependent Claim
29 words
A truss structure as in claim 1 wherein said apices of said first and second triangular wire members are welded to said first, second and third longitudinal wire members.
Claim 4
Dependent Claim
18 words
A truss structure as in claim 2 wherein said generally triangular shape of said wire members is sinusoidal.
Claim 5
Dependent Claim
17 words
A truss structure as in claim 3 wherein each of said generally sinusoidal wire members is uniplanar.
Claim 6
Dependent Claim
25 words
A truss structure as in claim 4 wherein said first longitudinal wire member is larger in diameter than said second and third longitudinal wire members.
Claim 7
Dependent Claim
84 words
A truss structure comprising: a. first and second serpentine shaped, elongated wire members, b. first, second and third elongated longitudinal bars, one of which bars is larger in thickness than the others, and c. means for coupling one set of apices of each of said serpentine wire members in staggered configuration to said larger bar and the other set of apices to a respective one of said remaining bars such that the first and second wire members are at an angle with each other.
Claim 8
Dependent Claim
84 words
A truss structure comprising: a. first and second serpentine shaped, elongated wire members, b. first, second and third elongated longitudinal bars, one of which bars is larger in thickness than the others, and c. means for coupling one set of apices of each of said serpentine wire members in staggered configuration to said larger bar and the other set of apices to a respective one of said remaining bars such that the first and second wire members are at an angle with each other.
Claim 9
Dependent Claim
30 words
A truss structure as in claim 6 wherein: a. said large elongared bar is 8 millimeters in diameter, and b. said two smaller elongated bars are 5 millimeters in diameter.
