STRESS TRANSMISSION STRUCTURE OF CAST-IN-PLACE STEEL PIPE CONCRETE PILE
To provide a stress transmission structure of a cast-in-place steel pipe concrete pile which can be easily formed, in which bleeding affection does not occur, and which is preferable in stress transmission performance.SOLUTION: In a stress transmission structure of a cast-in-place steel pipe concrete pile 1 formed of a steel pipe and concrete, a plurality of through holes 22 with a substantially circular shape in side view is provided at an end 21a of a cylindrical steel pipe 21 around and inside which concrete is filled with an interval in a circumference direction. Four to thirty-two through holes can be provided with a constant interval in a circumference direction according to a steel pipe size. The through holes can be provided by arbitrary steps of one to ten steps with an interval in an axial direction of the steel pipe.SELECTED DRAWING: Figure 1
【課題】簡単に製作できてブリージングの影響が生じないうえに、応力伝達性能に優れた場所打ち鋼管コンクリート杭の応力伝達構造を提供する。【解決手段】鋼管とコンクリートとによって形成される場所打ち鋼管コンクリート杭１の応力伝達構造である。そして、周囲及び内部にコンクリートが充填される円筒形の鋼管２１の端部２１ａに、周方向に間隔を置いて複数の側面視略円形の貫通穴２２が設けられていることを特徴とす。ここで、貫通穴は、鋼管サイズに応じて周方向に等間隔で４箇所から３２箇所が設けられる構成とすることができる。また、貫通穴は、鋼管の軸方向に間隔を置いて１段から１０段の任意の段数が設けられる構成とすることができる。【選択図】図１
