The present invention relates to a coupler for connecting a reinforcing steel bar which connects the reinforcing steel bar distributed in a building structure. The coupler for connecting the reinforcing steel bar according to an embodiment of the present invention includes: a coupler body which has a first reinforcing steel bar insertion hole and a second reinforcing steel bar insertion hole whose both sides are inserted with a reinforcing steel bar respectively; a node groove which is mounted with a node by being formed in a shape corresponding to the node formed around one circumferential side of the reinforcing steel bar on the inner side of the first and the second reinforcing steel bar insertion hole; a plain pressurizing plate which is mounted in an opposite direction to the node groove in each of the first and the second reinforcing steel bar insertion hole, and pressurizes the reinforcing steel bar inserted into the first and the second reinforcing steel bar insertion hole regardless of the shape of the node in the opposite direction mounted in the node groove; and a pressurizing fixing bolt which fixes the reinforcing steel bar to the coupler body by a method of pressurizing each pressurizing plate by a screw fastening force by penetrating the coupler body. Therefore, the reinforcing steel bar is not twisted and is fixed solidly in a straight line. |
