JOINT MEMBER, PILE FOUNDATION AND CONSTRUCTION METHOD OF THE PILE FOUNDATION
To provide a joint member which can be further easily constructed, a pile foundation and a construction method of the pile foundation.SOLUTION: A joint member 10 jointed to a pile head of a steel pipe pile 11 installed into the ground has: a covered cylindrical part 20 with a bottom face 23 opened and covered to the pile head from a lower side; and a projected part 30 projected upward from an upper end face 22 of the covered cylindrical part 20. An outer diameter of the covered cylindrical part 20 is larger than an inner diameter of the driving adapter of a pile driving machine, and an outer diameter of the projected part 30 is smaller than the inner diameter of the driving adapter. A shoulder part 22b is formed on a part with no projected part 30 positioned over the whole peripheral edge part of the upper end part 22 of the covered cylindrical part 20. A nut housing part 33 is formed inside the projected part 30, and a first through-hole communicated with the housing part 33 in a vertical direction and inserted with a bolt fastened with the nut is formed on an upper end face 32 of the projected part 30.SELECTED DRAWING: Figure 2
【課題】より容易に施工することができる接合部材、杭基礎および杭基礎の施工方法を提供する。【解決手段】地中に打設される鋼管杭１１の杭頭と接合する接合部材１０であって、下方端面２３が開放され、下方側から前記杭頭に被せられる被覆筒部２０と、前記被覆筒部２０の上方端面２２から上向きに突出する突出部３０と、を備え、前記被覆筒部２０の外径は、杭打ち機の打ち込みアダプタの内径よりも大きく、前記突出部３０の外径は、前記打ち込みアダプタの内径よりも小さく、前記被覆筒部２０の上方端面２２の周縁部には、全周にわたって前記突出部３０が位置しない肩部２２ｂが形成され、前記突出部３０の内部には、ナットの収容部３３が形成され、前記突出部３０の上方端面３２には、前記収容部３３と鉛直方向に連通し、前記ナットと締結するボルトが挿入される第１貫通孔が形成されている。【選択図】図２
