Abstract
The present invention comprises an improved composite wall structure which includes a pair of outer poured concrete layers which are separated by a high density foam insulating panel which is mounted between the concrete layers and includes a plurality of time mechanisms for holding the insulated layer in place while the concrete is being poured and hardened, wherein the holding means comprises metal rods and are low heat conductive rods such as polyglass impregnated plastic rods upon which a pair of holding spools are mounted which engage opposite sides of the insulating panel so as to hold it in a predetermined position. Also disclosed is a novel corner form arrangement.
Claims15
An insulating wall comprising two spaced outer layers of form-poured concrete;
- a high density insulating board disposed between said outer layers;
- a plurality of rods extending perpendicularly through said insulating layer and further extending substantially from respective outer surfaces of said outer layers;
- and a plurality of retainer means mounted to receive and immovably hold a rod for fixing the lateral position of said rods with respect to said insulation layer, whereby said rods abut said form during pouring of said concrete to retain said interior layer substantially immovably during pouring and are retained in said concrete after curing for forming a mechanical connection between said interior layer and each of said outer layers, wherein said retainer means comprises a pair of spools formed with central openings that can be inserted into opposite sides of said insulating board, wherein said spools each have an enlarged outer flange that can be depressed into the surface of said board and a central portion smaller than said flange, and wherein said spools also each have an inner portion which is larger than said central portion for locking said spool to said board.
An insulating wall comprising, two spaced outer layers of form-poured concrete, a high density insulating board disposed between said outer layers, a plurality of rods extending perpendicularly through said insulating layer and further extending substantially from respective outer surfaces of said outer layers, a plurality of retainer means mounted to receive and immovably hold a rod for fixing the lateral position of said rods with respect to said insulation layer, whereby said rods abut said form during pouring of said concrete to retain said interior layer substantially immovably during pouring and are retained in said concrete after curing for forming a mechanical connection between said interior layer and each of said outer layers, wherein said retainer means comprises a pair of spools formed with central openings that can be inserted into opposite sides of said insulating board, wherein said rods have projections thereon and a rod can be inserted through the central openings of a pair of said spools and locking means on each of said spools for locking the spools to said rod to hold said board in a predetermined spatial position between said outer layers of concrete, and wherein said central openings are a bayonet connection so that said rods and projections can pass therethrough in one angular orientation and said projections can be locked to said spools by rotating said rods relative to said spools.
