PILE HEAD JOINT CONSTRUCTION METHOD AND STRUCTURE HAVING PILE HEAD JOINT
PROBLEM TO BE SOLVED: To provide a pile head joint and its construction method, the pile head joint that has a simpler structure or construction method, in which the transmission of moment is prevented or reduced between a pile and a base beam, and strength to the force of a tensile direction and shift direction is provided.SOLUTION: A pile head joint 20 is constructed as follows: a formwork 22 provided with a hole of a predetermined radius is disposed so that a core rebar 26 penetrates through a hole part with respect to a pile head 13 having a predetermined curved surface shape and having a core rebar 26 of a pile projected into the upper side being an extending direction of the pile; the footing 16 is constructed by placing concrete so that the formwork 22 becomes the bottom; and thereby a circumferential edge of the hole part is made to come into contact with the pile head 13 slidably, and the formwork 22 is further brought into a line contact with the pile head 13 and the formwork 22 being slidable with the pile head 13 is provided.SELECTED DRAWING: Figure 7
【課題】より簡易な構造あるいは構築方法を有する杭頭結合部であって、杭と基礎梁との間でモーメントの伝達を防止もしくは低減し、引っ張り方向、ずれ方向の力に対する強度を有する杭頭結合部およびその構築方法を提供する。【解決手段】所定の曲面形状を有し、杭の芯鉄筋２６が杭の延伸方向である上側に突出させられた杭頭１３に対し、所定半径の孔部が設けられた型枠２２を、孔部を芯鉄筋２６が貫通するよう配設すると共に、型枠２２が底部となるようにコンクリートを打設することによりフーチング１６を構築することにより、孔部の周縁部と杭頭１３とが摺動可能に接触させられ、型枠２２にはさらに、杭頭１３に線接触し、杭頭１３と摺動可能な型枠２２が設けられるように、杭頭接合部２０が構築される。【選択図】図７
