Rebar coupler for beginning slip prevention
According to the present invention, a rebar coupler for preventing an initial slip comprises: first fastening members having first joint coupling grooves coupled to first joint portions formed on the outer circumferential surface of a first reinforcing bar for coupling, and coupled to the first reinforcing bar; a first anti-slip member screwed to the outer circumferential surface of the first fastening members to surround and support the first fastening members, and for providing a gripping force of the first reinforcing bar by the first fastening members; second fastening members having second joint coupling grooves coupled to first joint portions formed on the outer circumferential surface of a second reinforcing bar for coupling to the first reinforcing bar, and coupled to the second reinforcing bar; a second anti-slip member screwed to the outer circumferential surface of the second fastening members to surround and support the second fastening members, and for providing a gripping force of the second reinforcing bar; and a coupler body having first and second screw coupling portion screwed to the outer circumferential surfaces of the first and second anti-slip members, and maintaining a state in which ends of the first and second reinforcing bars coupled to have a length relatively greater than or equal to the sum of the lengths of the first and second anti-slip members are closely contacted to apply pressure. Therefore, a coupling defect in the rebar coupler can be prevented.
