ートブロツク接合部の構造である。Means for Solving Problems in the Structure of the Invention The present invention has a construction of a concrete block joint in which two concrete blocks are joined by bolts, with joining fittings buried in each end face of the joint. The joining flange fitting is buried so as to slightly protrude from the end face, and a recessed part with a tapered circumference is formed on the joining end face of the other block corresponding to the protruding part of the joining flange fitting, and a joining part is buried in the recessed part. This is a concrete block joint structure characterized by embedded flange fittings or anchor nuts.

行うことができる。Function In the present invention, a joining flange metal fitting is buried in one joint end surface so as to slightly protrude from the end surface, and a concave part with a taper around the circumference is formed correspondingly in the other joint end surface. Since the connecting flange metal fitting or the anchor nut is embedded, the protrusion of the metal fitting fits into the recessed part, so that both bolt holes can be perfectly aligned. Also,
The taper of the depression serves as a guide during positioning. That is, when both end surfaces are gradually brought closer together, the tip of the protruding portion of the metal fitting hits the taper and is gradually guided into the recessed portion along this taper. Therefore, the protruding portion and the recessed portion of the metal fitting can be easily fitted together.
