BOLT HOLDER OF CONNECTION BOLT OF STEEL PIPE PILE AND CONNECTING METHOD OF STEEL PIPE PILE
PROBLEM TO BE SOLVED: To provide a bolt holder mounted in a joint pipe in a steel pipe pile for use in connection of the steel pipe pile, the bolt holder that facilitates mounting of the bolt, the alignment between the tip of a bolt shaft section and a bolt hole of the joint pipe, and the work of drawing a tip portion of the bolt shaft section to the outside of the steel pipe pile.SOLUTION: A bolt holder 24 is mounted to a joint pipe 23 disposed inside of steel pipe piles 21, 22. A head 251 of a bolt 25 is held to a bolt head holding member 243, and a tip portion of a bolt shaft section 252 is inserted and held to the bolt hole 231 of the joint pipe 23. A male screw part 253 of the bolt 25 is drawn to the outside of the steel pipe pile 22 by using a bolt extractor, and a nut 26 is screwed and bolted to the male screw part 253.
【課題】鋼管杭の連結に用いる鋼管杭内の継手管に取り付けるボルト保持具において、ボルトの取り付け、ボルト軸部の先端と継手管のボルト孔との位置合せ、及びボルト軸部の先端部分を鋼管杭の外へ引き出 す作業が容易なボルト保持具を提供すること。【解決手段】鋼管杭２１，２２の内側に配置した継手管２３にボルト保持具２４を取り付けてある。ボルト２５の頭部２５１は、ボルト頭部保持部材２４３に保持され、ボルト軸部２５２の先端部分は、継手管２３のボルト孔２３１に挿入・保持される。ボルト２５の雄ねじ部２５３は、ボルト引出具を用いて鋼管杭２２の外へ引き出し、雄ねじ部２５３にナット２６を羅合してボルト締めする。【選択図】図２
