Claims

[Claims for Utility Model Registration] (1) In a joint for reinforcing bars in which at least one of the two reinforcing bars to be connected is a threaded reinforcing bar having a spiral convex portion on the outer periphery, one end of the joint body has the above-mentioned screws. A screw hole is provided into which the spiral protrusion of the reinforcing bar can be screwed, and the other reinforcing bar can be inserted into the other end of the joint body by attaching an engagement member with a larger diameter than the reinforcing bar to the tip. A joint for reinforcing bars, characterized in that a hole is provided through which the other reinforcing bar is inserted and a screw member that engages with the engaging member can be screwed into the hole. (2) The joint for reinforcing bars according to claim 1, wherein a side portion of the joint body is provided with a grout inlet that communicates with the hole at the other end of the joint body.
