Claims (2)
- 上下鋼管杭の接続端部に互いに挿脱可能な雌円筒と雄円筒とをそれぞれ備え、該雄雌円筒の先端側の嵌合面にそれぞれ相手側の嵌合面に遊合する円弧板状突起を、円周方向に交互に設けてなり、雄円筒を雌円筒中に挿入後、上下杭を相互に軸周りに回動させて上下杭を接続する接続構造において、
該円弧板状突起の杭端側端面に相手方円筒に設けた円周溝と係合する印籠構造を設け、該円弧板状突起の反杭端側の端面は上下杭接続後に相互に細隙を以て対向すると共に接触により上下杭の鉛直方向力を伝達する杭軸直交面とし、上下杭に回転力を伝達するキー部材を該雄雌円筒間に介装したことを特徴とする鋼管杭接続構造。 - 前記円弧板状突起の反杭端側の端面を、杭軸方向に対して傾斜して互いに係止する円錐台側面形状に変更し、前記円弧板状突起を相互に蟻差し状に係合させることを特徴とする請求項1記載の鋼管杭接続構造。
