PROBLEM TO BE SOLVED: To provide a sheath coupler capable of preventing a deterioration in workability by preventing an opening end from being crushed during concrete placement and the like, because the opening end of a sheath connection pipe for being embedded in a concrete segment is provided with a reinforced part.SOLUTION: A reinforced rib 4 (a reinforced part) is formed at an opening end, which faces an end surface 11a of a concrete segment 11, of an outer pipe 2 (a sheath connection pipe). In the butting end surface 11a of the concrete segment 11, an inner pipe 3 (an insertion pipe) is inserted into the pair of opening ends in such a manner as to straddle the pair of abutting opening ends of the outer pipe 2.SELECTED DRAWING: Figure 1
【課題】コンクリートセグメントに埋設されるシース接続管の開口端に補強部を設けたことにより、コンクリート打設時等に開口端が潰れないようにして作業性の悪化を防止することができるシース接続具を提供する。【解決手段】外管２（シース接続管）における、コンクリートセグメント１１の端面１１ａに臨む開口端に補強リブ４（補強部）を形成する。突き合わされたコンクリートセグメント１１の端面１１ａにおいて、外管２の当接した一対の開口端を跨ぐように、これら一対の開口端の内部に内管３（挿入管）を挿入する。【選択図】図１
