Abstract
Abstract A reinforced structural panel having an integral, rigid core member of insulating material provided with a plurality of embedded serpentine or zig-zag shaped reinforcing rods is disclosed for fabricating walls of buildings and the like. The core member is provided with a plurality of slits on either major surface arranged in a matrix of rows and columns. The reinforcing rods are inserted into the core member along alternate rows from opposite surfaces of the core member. A wire mesh grid is positioned overlying the major surfaces and attached to the projecting portions of the reinforcing rods. A series of the resulting structural panels can be interconnected into a wall at the job site and thereafter covered with a layer of cementitious material.
