Thin metal anchoring plates provide mechanical bonding between flooring materials such as concrete and plywood. Teeth punched from the metal plates and bent at right angles on the topside form anchorage for the concrete slab and metal screws anchor the metal plate to the plywood subfloor. The metal anchoring plates allow a thin layer of concrete to form a composite section with residential floor construction and to stay in compression-a state in which cracking cannot occur in concrete. Thus, two inherent problems associated with concrete-it's heavy weight and propensity for cracking are solved and thus, allow it now to be used for residential seamless flooring that can be colored, stamped, and textured, for years of low maintenance fire resistant use.
