ンクリートセグメントの継手構造。[Claims for Utility Model Registration] (1) A recess is provided near the joint end face of at least one of a pair of concrete segments to be connected, and a bolt insertion hole is formed from the recess across the joint end face, The other concrete segment has a bolt insertion hole extending inward from the joint end surface, and a small-diameter tapered nut member is installed at the inner end into which the bolt inserted into the bolt insertion hole is screwed. The nut member is buried in advance with the part side facing the joint end surface, and the joint end surfaces of both bolt insertion holes are brought together in a continuous state, and the bolts inserted into both bolt insertion holes are inserted into the nut member. A concrete segment joint structure characterized by being connected by screwing and fastening. (2) Recesses are provided in the vicinity of the joint end surfaces of the pair of concrete segments to be connected, and bolt insertion holes are formed from these recesses to the joint end surfaces, and furthermore, a recess is formed on the side of the recess of these bolt insertion holes. A tapered bolt fixing part is arranged on one side of the opening, and a tapered nut receiving seat is arranged on the other side, with the small diameter part facing the joint end surface,
The joint end surfaces of both bolt insertion holes are brought together in a continuous state, and the bolts inserted through both bolt insertion holes are screwed into the nut member that fits into the nut receiving seat. A joint structure of concrete segments, characterized in that the concrete segments are fixed at the fixing portion.
