<p>Disclosed herein is a reinforcing bar coupler which is intended to easily couple reinforcing bars in reinforced concrete work, thus reducing a construction period and construction costs. The reinforcing bar coupler includes a cover unit to cover reinforcing bars, and a locking bushing fitted over the cover unit to firmly couple the cover unit to the reinforcing bars. The cover unit has a circular hole therein, and includes two or more pieces to cover circumferences of the reinforcing bars. Outer surfaces of the pieces are inclined in the same direction to form a tapered surface, and annular grooves are provided on an inner surface of each piece to receive annular ribs in the annular grooves. The locking bushing comprises at least one locking bushing, and has on an inner surface thereof a tapered surface to correspond to the tapered surface of the cover unit.</p> |
