ABSTRACT:
A joint for reinforcing bars includes a joint main body having a pair of substantially parallel side walls and at least one curved wall which connects together the end edges of both side walls, together and a wedge inserted into wedge bores which are respectively provided in the side walls in such a manner so as to be aligned with each other. The end portion of each of the reinforcing bars which are to be connected together are set in such a manner so as to contact the inside of the curved wall, and the wedge is press-fitted into the wedge bores. Thus the end portion of each reinforcing bar is clamped and thereby rigidly secured between the wedge and the curved wall. The curved portion is formed so as to have a substantially V-shaped inner wall surface including a pair of slanting surfaces. Thus, the end portion of each of the reinforcing bars which is pressed by the wedge is pressed against the pair of slanting surfaces and allowed to bite into the area defined therebetween.
