Abstract
A wall form system for use in constructing a poured concrete wall includes a plurality of panels aligned in an edge-to-edge configuration to form spaced wall forms. The wall forms are maintained in a spaced relationship by a tie which includes a pair of cutouts which mate with notches in the side edges of each of the panels at the juncture between adjacent panels. A retainer is provided to secure each end of the tie to the outer face of the adjacent panels. After the concrete wall is poured and hardened, the wall forms are easily disassembled by breaking a first frangible section from the tie and removing the wall form panels and then breaking a second frangible section from the tie which is projecting from the concrete wall. The ties and retainers are disposable and easily assembled with the wall forms thereby alleviating the need for collection and retrieval when the wall forms are disassembled. Further, the wall panels consist of multi-layer composite construction which provides sufficient strength and durability to the wall form system with a lightweight and easily handled and maneuvered panel that can be reused for subsequent poured concrete wall applications.
