PILE HEAD STABILIZATION MEMBER AND PILE FOUNDATION FOOTING STRUCTURE USING THE SAME
PROBLEM TO BE SOLVED: To provide a pile head stabilization member and a pile foundation footing structure using the same, capable of restraining the occurrence and propagation of a crack in a footing part caused by an earthquake.SOLUTION: A pile head stabilization member 10 is an anticorrosive member arranged on leveling concrete 1 placed around a pile head part P1 in a state of surrounding the periphery of the pile head part P1 projected from a ground G. The pile head stabilization member 10 comprises a reinforcement member 11 arranged on the leveling concrete 1 in a state of enclosing the periphery of the pile head part P1, and a plurality of holding members 12 joined to the reinforcement member 11 for holding the reinforcement member 11 in a constant attitude in a position separated at a predetermined interval from the pile head part P1 and the leveling concrete 1. The reinforcement member 11 is a circular member capable of enclosing the periphery of the pile head part P1 in a position not in contact with the outer periphery of the pile head parr P1, and the holding members 12 comprise a positioning part 12c projected toward the outer periphery of the pile head part P1 from the reinforcement member 11.SELECTED DRAWING: Figure 2
【課題】地震などに起因する、フーチング部分におけるクラックの発生や伝播を抑制することができる杭頭安定化部材及びこれを用いた杭基礎フーチング構造を提供する。【解決手段】杭頭安定化部材１０は、地盤Ｇから突出した杭頭部Ｐ１の周りを囲繞した状態で、杭頭部Ｐ１の周囲に打設された捨てコンクリート１上に配置される耐食性の部材である。杭頭安定化部材１０は、杭頭部Ｐ１の周りを囲んだ状態で捨てコンクリート１上に配置される補強部材１１と、補強部材１１を、杭頭部Ｐ１及び捨てコンクリート１から所定間隔離れた位置で一定姿勢に保持するため補強部材１１に接合された複数の保持部材１２と、を備えている。補強部材１１は、杭頭部Ｐ１の外周に接触しない位置で杭頭部Ｐ１の周りを包囲可能な円形の部材であり、保持部材１２は、補強部材１１から杭頭部Ｐ１の外周に向かって突出した位置決め部１２ｃを有する。【選択図】図２
