CONSTRUCTION JIG OF ROTARY PILE, AND CONSTRUCTION METHOD OF ROTARY PILE
To provide a construction jig of a rotary pile capable of making a construction jig lightweight in constructing a joint structure mechanically connecting upper and lower rotary piles.SOLUTION: A construction jig 10 of a rotary pile is used in a joint structure of a rotary pile connecting upper and lower rotary piles by a mechanical joint structure, and attached to a joint member provided at an end portion of the rotary pile. The construction jig 10 comprises: a joint engagement portion 11 engaging with the joint member; a rotary shaft engagement portion 12 which is constituted of a ring-like body concentric with the rotary pile, in which a plurality of engaging protrusions 13 are provided on an outer periphery of the ring-like body, and which engages with an engaging piece 22C of a rotary shaft of a heavy machine that rotates the rotary pile; and a reinforcement member 14 provided inside the ring-like body of the rotary shaft engagement portion 12.SELECTED DRAWING: Figure 4
【課題】上下の回転杭を機械的に連結する継手構造の施工に際して、施工治具の軽量化を図ることのできる回転杭の施工治具を提供すること。【解決手段】上下の回転杭を機械式継手構造により連結する回転杭の継手構造に用いられ、回転杭の端部に設けられた継手部材に取り付けられる回転杭の施工治具１０は、継手部材と係合する継手係合部１１と、回転杭と同心のリング状体から構成され、リング状体の外周に複数の係合突起１３が設けられ、回転杭を回転させる重機の回転軸の係合片２２Ｃと係合する回転軸係合部１２と、回転軸係合部１２のリング状体の内部に設けられた補強部材１４と、を備える。【選択図】図４
