Claims

[Scope of utility model registration request]

A joint fitting buried opposite the circumferential joint end faces of concrete segments of arc-shaped plates to be joined to each other, the joint metal fittings being arranged on the inner peripheral side of the concrete segments of the joint end faces, and having a plate shape with bolt insertion holes formed therein. a metal fitting body, a joint material fixed to the back side of the metal fitting body and extending inward of the concrete segment, and a bearing material arranged on the outer peripheral edge of the concrete segment on the joint end surface and fixed to the joint material. A joint fitting for a concrete segment, characterized in that the bearing material is provided so that its surface comes into contact with the bearing pressure material of the mating joint fitting when both joint end surfaces are brought together. .
