<p>The present invention relates to a reinforcement bar coupler for coupling sockets using a joint end member and, more specifically, to a reinforcement bar coupler for coupling sockets using a joint end member, which is capable of precisely and mechanically connecting reinforcement bars, whose ends are contiguous with each other, by simply coupling sockets, wherein the reinforcement bars have joint ends joined thereto to facilitate connecting construction between the reinforcement bars and reinforcement bar cages forming a reinforced concrete foundation. The reinforcement bar coupler comprises: first and second reinforcing bars having ends faced and contiguous with each other; a first joint end member welded to the end of the first reinforcing bar and having a male thread formed on the outer circumferential surface in a length direction; a second joint end member having one side end having a shape corresponding to the shape of the end of the first joint end member, the other sided end welded to the end of the second reinforcing bar, spaced apart from the one side end, and including one or more end steps which have an one end in an axial direction at one selected from acute, right, and obtuse angles to a lengthwise direction; and a hollow-shaped coupling socket which is extended in a longitudinal direction to surround the outer surfaces of the second joint end member and the first joint end member, has a coupling socket connection female thread part formed thereon in a lengthwise direction, and includes one or more catching grooves which are caught by the end step of the second joint end member, and are at one selected form acute, right, and obtuse angles to a lengthwise direction, wherein the coupling socket connection female thread part is screw-combined with a coupling socket connection male part of the first joint end member inside the coupling socket.</p> |
