To simplify a fixing work with a structural reinforcement of footing and make a pile head part of a precast pile correspond to a steel beam of the footing, when the pile head part is embedded in the footing.SOLUTION: An existing pile 1 is composed of a base part 2 and a pile head part 5, where the pile head part 5 has a pile head part body 6 having a regular hexagonal shape and a shape adjustment part 19 of which a contour changes to the base part 2, and has parallel linear heads 10A and 10A by the regular hexagonal shape of the pile head body 6. The existing pile 1 is embedded into a drilled pile hole 21 in a state where the existing pile is connected to the uppermost part of other existing pile 2. At this time, a reinforcement 27 for connection that is fixed vertically to the pile head body 6 can be easily fixed to a structural reinforcement 31 of a footing of a ground structure without bending the reinforcement for connection by aligning preset directions of the linear heads 10A and 10A with the structural reinforcement 31.SELECTED DRAWING: Figure 15
【課題】既製杭の杭頭部をフーチング内に埋設するに際して、フーチングの構造鉄筋との定着作業を簡略化させ、かつフーチングの鉄骨梁にも対応させる。【解決手段】既製杭１は基部２と杭頭部５から構成し、杭頭部５は、正六角形の杭頭部本体６と、外形が基部２に変化する形状調整部１９を具え、杭頭部本体６の正六角形により平行な直線状辺１０Ａ、１０Ａなどを有する。掘削した杭穴２１内に他の既製杭２の最上に既製杭１を連結した状態で埋設する。この際、予め設定した直線状辺１０Ａ、１０Ａの方向を、地上構造物のフーチングの構造鉄筋３１に合わせれば、杭頭部本体６に縦に固定する連結用鉄筋２７を曲げることなく容易に、構造鉄筋３１に定着できる。【選択図】図１５
