A hand held applicator tool for applying deformable metal fastener clips to secure together reinforcement steel members used in concrete construction. 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 fastener clips can be easily placed over the reinforcement steel members. The tool comprises a frame, an anvil supported at one end of the frame, a movable blade assembly supported for sliding movement along the frame toward the anvil, and a handle for manipulating and positioning the tool. The movable blade assembly has a generally U-shaped receptacle for holding a fastener clip. The anvil has a pair of machined grooves for guiding the first and second legs of a fastener clip generally toward one another to close the open side of the fastener clip and deform the first and second legs to clamp tightly around the reinforcement members. The steel reinforcement members can thus be secured together in substantially less time than with other conventional methods, and with substantially less cost in both materials and labor. The applicator tool design can also be used for applying deformable fastner rings during the manufacture of automotive seating, upholstery, furniture, bedding, and other applications where hog ring fasteners are conventionally used. |
