Abstract

Abstract A wire matrix for a construction panel has a plurality of parallel longitudinal trusses, each truss having a pair of parallel longitudinal wire runners and a plurality of transverse wire struts in which the struts associated with one truss are all parallel to each other and extend diagonally between the parallel runners, with the struts in alternate ones of the trusses being parallel and the struts in adjacent trusses being skewed. The trusses are formed by making a grid of parallel longitudinal runners joined by diagonal cross wires which are then cut between adjacent pairs of runners to form separate trusses. The trusses are then joined by transverse wire runners forming a three-dimensional matrix.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 273 words
The method of making a three-dimensional wire matrix composed of a plurality of wire trusses comprising the steps of: feeding a plurality of truss longitudinal runner wires along parallel paths in a common plane with the spacing between adjacent wires of each pair being substantially less than the spacing between the wires of each pair, laying a plurality of spaced parallel truss strut cross-wires against the runner wires, each of the cross-wires bridging all of the runner wires and being disposed diagonally relative to the runner wires, securing each of the cross-wires to the runner wires at the points of intersection to form a two-dimensional wire grid, cutting each of the cross-wires after it is secured to the runner wires between each adjacent pair of runner wires to form a plurality of separate trusses each of which has parallel struts disposed diagonally between and connected to two parallel longitudinal truss runners, twisting each of the separate trusses about its length through an angle of 90° so that the plane defined by the struts and runners of each truss is parallel to the corresponding plane of the other trusses, adjacent trusses being twisted in opposite rotary directions, contacting both of the longitudinal runner wires of each of the separate trusses at spaced locations therealong by a plurality of parallel matrix transverse wires disposed in two parallel planes perpendicular to the planes of the trusses, and attaching the matrix transverse wires to the truss runners to secure the transverse wires and the trusses in a matrix framework in which the struts in adjacent trusses slope in opposite directions relative to the runners of the trusses.
