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: 4
Claim 1
Independent Claim
150 words
A construction panel comprising: a metal wire lattice type framework including a plurality of spaced parallel essentially planar longitudinal trusses, each truss consisting of an upper and a parallel lower longitudinal wire runner and a plurality of transverse wire struts, each strut being secured to the upper and lower runners of its truss, all of the struts associated with one truss being parallel to each other and extending diagonally at an acute angle relative to the runners, and a plurality of upper and lower transverse wire runners intersecting respectively the upper and lower runners of the trusses, the longitudinal and transverse runners being joined at their intersections, the struts in every second one of the trusses extending diagonally in one direction and the struts in the intermediate trusses extending diagonally in the opposite direction so that the struts in one truss are askew to the struts in each adjacent truss.
Claim 2
Dependent Claim
150 words
A construction panel comprising: a metal wire lattice type framework including a plurality of spaced parallel essentially planar longitudinal trusses, each truss consisting of an upper and a parallel lower longitudinal wire runner and a plurality of transverse wire struts, each strut being secured to the upper and lower runners of its truss, all of the struts associated with one truss being parallel to each other and extending diagonally at an acute angle relative to the runners, and a plurality of upper and lower transverse wire runners intersecting respectively the upper and lower runners of the trusses, the longitudinal and transverse runners being joined at their intersections, the struts in every second one of the trusses extending diagonally in one direction and the struts in the intermediate trusses extending diagonally in the opposite direction so that the struts in one truss are askew to the struts in each adjacent truss.
Claim 3
Dependent Claim
27 words
The panel of claim 1 having a unitary mass of rigid plastic foam material embedded in the framework, the material surrounding and being bonded to the struts.
Claim 4
Dependent Claim
48 words
A panel according to claim 1 in which the struts and the transverse runners are regularly spaced along the trusses, and the regular spacing of the truss struts and the transverse runners is essentially equal to the spacing between the upper and lower longitudinal runners in each truss.
