Title:
APPARATUS AND METHOD FOR APPLYING DEFORMABLE METAL FASTENER CLIPS TO CONCRETE REINFORCEMENT STEEL
Document Type and Number:
WIPO Patent Application WO1999012708
Kind Code:
A3
Abstract:
A hand held tool (60) and method for applying deformable metal fastener clips (10, 20) to reinforcement steel members (50, 51) used in concrete construction. The deformable metal fastener clips are generally U-shaped members that are open on one side before being deformed. The tool comprises a frame (61), an anvil (62) supported at one end of the frame, a movable blade assembly (63) supported for sliding movement along the frame toward the anvil, and a handle (64) for manipulating and positioning the tool. The movable blade assembly has a generally U-shaped receptacle (79) for holding a fastener clip. The anvil has a pair of machined grooves (77, 78) 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.
