ABSTRACT:
An apparatus and method for fastening concrete reinforcement steel members together using deformable metal fastener clips. The concrete reinforcement steel members are used to strengthen concrete structures in a known manner and can be in the form of wire mesh sheets or rebar positioned in a grid pattern. The deformable metal fastener clips are generally U-shaped members that are open on one side before being deformed so that the fastening clips can be easily placed over two or more adjacent reinforcement steel members. The metal fastener clips are deformed around the reinforcement steel members to close the open side of the metal fastener clips, thereby securing the reinforcement steel members together in a desired formation. The free ends of each fastener clip preferably overlap each other after the fastener clips are closed around the reinforcement steel members. The reinforcement steel members can be secured together within a concrete form, or they can be secured together offsite and placed in a concrete form before filling the form with concrete. The deformable fastener clips can be used to efficiently secure reinforcement steel members together during concrete construction with a simple squeeze of the fastener clips around the reinforcement steel members. The steel members can thus be secured together in substantially less time than other conventional methods, and with substantially less cost in both materials and labor.
