  • Patent number: 6581346
    Abstract: 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.

  • Patent number: 4862667
    Abstract: A one-piece structural member with integral fastener prongs for joining to a separate penetrable plate such as plywood or the like. The structural member is formed with at least one web section and with at least one continuous perpendicular flange section having the fastener prongs formed therein. The continuous flange section with the integral web section permits a large variety of prong sizes, spacings and structural configurations to be obtained thereby producing a large variety of panel and beam stiffness and span lengths. The method disclosed herein permits the construction of novel composite structural panels and beams at a job site using the one-piece structural member which is pressed together with a penetrable plate such as plywood, wood studs or the like by means of a pair of pressure rollers, a press brake or other means.
