INSERTION TOOL FOR FORMING SHEATH CONNECTION PORT AND FORMING METHOD OF SHEATH CONNECTION PORT
To provide a forming method of a sheath connection port capable of forming a sheath connection port in a simple structure without any displacement and securely without any peeling damage of concrete.SOLUTION: End surfaces 2a of a pair of concrete segments 2 formed in a condition that a concrete form 1 abuts an insertion tool 10 for forming a sheath connection port have an outer diameter of a central part in a longitudinal direction inserted in an opening 1a of the concrete form 1, which are designed larger than inner diameters of opening ends 3a of a pair of sheath connection tubes 3, respectively.SELECTED DRAWING: Figure 1A
【課題】簡単な構成でずれることなく確実にコンクリートの剥がれ損傷のないシース接続口を形成する。【解決手段】シース接続口成形用挿入具１０に、型枠１を介して突き合わされた状態で成形される一対のコンクリートセグメント２の端面２ａにおいて、型枠１の開口１ａに挿入される長手方向中央部の外径を一対のシース接続管３の開口端３ａの内径よりも大きくした。【選択図】図１Ａ
