A circular opening is provided on the top surface of a joining fixture having an elliptical through hole into which two steel bars can be inserted loosely, and a screw hole is provided on the circular opening and communicates with the opening. A bolt-receiving metal fitting equipped with a bolt-receiving metal fitting is fixed in an upright position, and a circular opening with a diameter slightly smaller than the circular opening is provided on the lower surface of the joint-fixing metal fitting, and a circular opening with a diameter slightly smaller than that is provided on the lower surface of the joint-fixing metal fitting. a curved concave tapered surface is provided, and a curved convex tapered surface is provided to the lower end on two surfaces sandwiched between the curved concave tapered surfaces, and an acute angle is formed at the joint of each of the tapered surfaces. A wedge is formed by providing an inset edge,
and inserting the wedge material into the bolt receiving metal fitting, inserting the lower part thereof into the small diameter circular opening through between the two steel bars, and tightening the tightening bolt screwed onto the wedge material, This device for joining and fixing steel bars is made by lowering a wedge material so that the biting edge of the wedge material bites into two steel bars. 2. The tightening bolt has a threaded rod at the bottom, and fixes a small diameter shaft above the threaded rod, and
Claim 1: A tightening head is provided at the upper end of the shaft.
The described steel bar joining and fixing device.
