Abstract
Abstract A multi-reinforced construction panel comprising a metal wire mesh or plate folded by a press machine to take the shape of acute V formations, square wave formations, natural wave formations, or trapezoidal formations to work structurally as folded plates. Both side of said folded metal mesh or plates are covered with two metal meshes shaped like two flat panels, to be secured to embodiments by welding. The two flat metal meshes can have different fabric to enforce the framework structurally a light-weight raw material, such as expanded polystyrene or foamed PU, is used to insert onto the back and loin sections of the metal wire skeleton structure produced accordingly, so as to build up an accomplished multi-reinforce construction panel.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
83 words
A structural rreinforcement grid consisting essentially of two substantially planar sections of wire mesh and a third section of multiply-pleated wire mesh or of multiply-pleated metal plate; the third section having a configuration, in profile, of acute "V" formations, natural wave formations, square wave formations or trapezoidal formations; said third section being sandwiched between and welded to each of the two substantially planar sections at points of contact; and the grid being one wherein said substantially planar sections lie in substantially parallel planes.
Claim 2
Dependent Claim
83 words
