IRON BAR COUPLER AND METHOD FOR COUPLING IRON BAR USING IRON BAR COUPLER

摘要

invention by compression and tension in joints reinforced with rebar couplers, and this way for that, the joints of reinforced lined solve the problem by lap joints and connections, but by combining the coupler reinforced by a screw, even when cutting the rebar is deformed or burrs can occur while screwed on the rebar coupler rebar may be bonded firmly to the coupler, and by applying a compressive force and a pulling force for the purpose of ensuring protection for the reinforcement of reinforced concrete structures due to external forces of tension and compression. Compression and tension is reinforced by a coupler according to the present invention is formed on the inner peripheral surface of the threaded tube structure while both sides in the longitudinal direction within each opening, threaded on the outer peripheral surface (1a, 2a) the first and second reinforcement (1 is formed, 2) with the screw that binds port 10 on both sides respectively; The sphere is bound to screw the first and second reinforced solidarity, but solidarity in the sphere with the first and second reinforcement, each node has two neighbors that the solidarity sphere with mountains of threads of the first and second reinforcement Mountain (12) between the bone (13) is inserted into the first and second reinforcement of solidarity and the solidarity sphere as well as in conjunction with coil springs in the form of reinforced cohesion to grant a compressive force to the first and second reinforcement (20); The coupling length in the direction of both sides of each sphere is screwed to the first and second reinforcement is composed of the first and second nuts (30, 40) for imparting tension to the first and second reinforcement.
