SHEATH COUPLER, INSERTION TOOL FOR FORMING SHEATH END CONNECTION, AND CONCRETE SEGMENT INSTALLATION METHOD
To allow the installation of concrete segments, including those for floor slabs that are thin, while ensuring rigidity around a sheath coupler.SOLUTION: A sheath coupler 20 for connecting open ends 3a of a pair of sheath connecting pipes 3 facing each other at sheath end connections 2b of end faces 2a of a pair of concrete segments 2 in which a sheath 4 for inserting a PC steel wire is embedded, comprises: a pair of joint members 21 inserted into a pair of sheath end connections 2b, respectively, whose rear side end parts are inserted into the open ends of the sheath 4; and a flexible hose member 22, fitted to the other end of the pair of joint members 21, which hermetically connects the pair of joint members 21. Step parts 21a on which the end part of the flexible hose member 22 abuts are formed on the other end sides of the joint members 21.SELECTED DRAWING: Figure 2
【課題】コンクリートセグメント、中でも厚さの薄い床版用のコンクリートセグメントであっても、シース接続具周辺の剛性を確保しながら施工できるようにする。【解決手段】ＰＣ鋼線を挿通するシース４が埋め込まれた一対のコンクリートセグメント２の端面２ａのシース接続口２ｂにおいて対向する一対のシース接続管３の開口端３ａを互いに接続するシース接続具２０において、一対の上記シース接続口２ｂにそれぞれ挿入され、奥側端部がシース４の開口端に挿入される一対の継ぎ手部材２１と、一対の継ぎ手部材２１の他端側に嵌合され、これら一対の継ぎ手部材２１を密閉状に連結する可撓性ホース部材２２とを設ける。継ぎ手部材２１の他端側に、可撓性ホース部材２２の端部が当接する段部２１ａを形成する。【選択図】図２
