To provide a winged pile with high performance with less stress concentration.SOLUTION: In a disclosed winged pile 1, a flat plate blade 5 or a pseudo-helical blade with a diameter larger than the diameter of a tube 3 is attached to the tip of the tube 3 in an axially inclined state that is inclined with respect to the central axis of the tube 3 on the tip of the tube 3. Both the inner and outer sides of the tube 3 at the distal end surface of the tube 3 that are in contact with the upper surface of the flat plate blade 5 or the pseudo-helical blade are in contact with the upper surface of the flat plate blade 5 or the pseudo-helical blade over the entire circumference.SELECTED DRAWING: Figure 1
【課題】応力集中が生じにくく性能の高い翼付き杭を提供する。【解決手段】本発明に係る翼付き杭１は、円筒状の管３の先端に、管３の直径より大きな直径を持った平板翼５又は疑似螺旋翼を、管３の中心軸に対して傾斜する軸方向傾斜した状態で管３の先端部に取り付けたものであって、平板翼５又は前記疑似螺旋翼の上面と当接する管３の先端面における管３の内面側と外面側の両方が、平板翼５又は前記疑似螺旋翼の上面に全周にわたって接している。【選択図】 図１
