PILE HEAD MEMBER OF PRECAST PILE
To provide a pile head member that can suppress inclination of precast piles built into pile holes.SOLUTION: A pile head member 10 of a precast pile includes: multiple engaging fittings 1 each whose base end part is fixed on an upper end of an approximately cylindrical precast pile 20, which extend in a diameter direction of the precast pile 20 from a central axis O of the precast pile 20 and engage with a lower end of a pile driver; and regulation fittings 2 which are respectively fixed to tip parts that are located outside the precast pile 20 of the engaging fittings 1 and have surfaces 2a that are wider than diametrically outside end surfaces of the precast pile 20 of the tip part of the engaging fitting 1 on end surfaces of the direction.SELECTED DRAWING: Figure 1
【課題】杭孔に建て込んだ既製杭の傾きを抑制することが可能な杭頭部材を提供する。【解決手段】既製杭の杭頭部材１０は、略円筒形状の既製杭２０の上端部に基端部が固定され、既製杭２０の中心軸Ｏから既製杭２０の直径方向に延び、杭打機の下端部と係合する複数の係合金具１と、係合金具１の既製杭２０より外側に位置する先端部にそれぞれ固定され、係合金具１の先端部の既製杭２０の直径方向外側の端面よりも広い面２ａを当該方向の端面に有する規制金具２とを備える。【選択図】図１
