PILE HEAD CONNECTION STRUCTURE AND METHOD FOR CONSTRUCTING PILE HEAD CONNECTION STRUCTURE
To provide a pile head connection structure and a method for constructing the pile head connection structure, in which the bending moment acting on the pile head of a cast-in-place concrete pile is reduced and the compression resistance is improved.SOLUTION: A pile head connection structure comprises a concrete body 60 placed in the ground, a reinforcing bar cage 10 arranged inside the concrete body 60, a lower core reinforcing bar 51 attached to the axial center side of the reinforcing bar cage 10 and extending downward from a pile head and at least partially embedded in the concrete body 60, a cylindrical connecting member 50 attached at one end so as to cover an upper end of the lower core reinforcing bar 51, and an upper core reinforcing bar 52 inserted into the other end of the connecting member 50 and rotatably attached and embedded in the foundation (footing 5, foundation beam 6). The upper core reinforcing bar 52 is formed in a crank shape.SELECTED DRAWING: Figure 1
【課題】場所打ちコンクリート杭の杭頭に作用する曲げモーメントを小さくすると共に、耐圧縮性を向上させた杭頭接続構造及び杭頭接続構造の施工方法を提供する。【解決手段】地中に配置されるコンクリート体６０と、コンクリート体６０の内部に配置される鉄筋籠１０と、鉄筋籠１０の軸心側に取り付けられる、杭頭から下方に延在してコンクリート体６０に少なくとも一部が埋設される下芯鉄筋５１と、下芯鉄筋５１の上端を覆うように、一端が取り付けられる筒状の接続部材５０と、接続部材５０の他端に挿入されて回転可能に取り付けられるとともに、基礎部（フーチング５，基礎梁６）に埋設される上芯鉄筋５２と、を備え、上芯鉄筋５２は、クランク状に形成されている。【選択図】図１
