CONCRETE PILE
PROBLEM TO BE SOLVED: To provide a concrete pile, the flexural capacity and shear capacity of which become greater than ever.SOLUTION: A concrete pile comprises a cylindrical pile body part 5 that contains concrete and that has a hollow part 11, and a spiral member 3a that is arranged in the hollow part 11 of the pile body part 5 and spirally extends around an axis line of the pile body part 5 along an inner peripheral surface 13 of the pile body part 5. The spiral member 3a is brought into elastic contact with the inner peripheral surface 13 of the pile body part 5 so as to urge it toward the radial outside of the pile body part 5.SELECTED DRAWING: Figure 1
【課題】曲げ耐力及び剪断耐力が従来よりも改善されたコンクリート杭を提供する。【解決手段】コンクリート杭は、コンクリートを含み、中空部１１を有する円筒形状の杭本体部５と、杭本体部５の中空部１１に配置され、杭本体部５の内周面１３に沿って杭本体部５の軸線の周りを螺旋状に延びる螺旋部材３ａと、を備える。螺旋部材３ａは、杭本体部５の径方向外側に向かって付勢するように杭本体部５の内周面１３に弾性的に接触している。【選択図】図１
