To provide a bolt support unit which achieves improvement of installation workability and installation accuracy of a fastener to a bolt, and an increase in load resistance.SOLUTION: A bolt support unit 1 includes: a bolt 3 having a first male screw part 3a; and a fastener 4 fixed to the bolt 3. The fastener 4 has: a sleeve 20 having a body composed of a pair of half-split bodies 21a and 21b, a first female screw part 23 formed on an inner peripheral surface of the body, and a second male screw part 24 formed on an outer peripheral surface of the body; and a fixing member 10 having a fixing inner peripheral surface 12 formed with a second female part 11. The pair of half-split bodies 21a and 21b are connected to each other so as to sandwich the bolt 3, thereby the first female part 23 is engaged with the first male screw part 3a from a crossing direction crossing a screwing and advancing direction to the first male screw part 3a, the fixing member 10 is inserted from a tip of the bolt 3 while maintaining the engagement state, and the second female part 11 is screw-engaged with the second male screw part 24, and thereby the sleeve 20 is supported by the bolt 3.SELECTED DRAWING: Figure 6
【課題】ボルトに対する止め具の設置作業性向上、設置精度向上、及び耐荷重増大を実現するボルト支持ユニットを提供する。【解決手段】ボルト支持ユニット１は、第１おねじ部３ａを有するボルト３と、ボルト３に固定される止め具４とを備え、止め具４は、一対の半割体２１ａ、２１ｂからなる本体、本体の内周面に形成される第１めねじ部２３、本体の外周面に形成される第２おねじ部２４を有するスリーブ２０と、第２めねじ部１１が形成された固定内周面１２を有する固定部材１０とを有し、ボルト３を挟むようにして一対の半割体２１ａ、２１ｂを連結することにより第１おねじ部３ａに対する螺進方向と交差する交差方向から第１めねじ部２３が第１おねじ部３ａに係合され、当該係合状態を維持しながら固定部材１０をボルト３の先端から挿通させて第２おねじ部２４に第２めねじ部１１を螺合させることによりスリーブ２０がボルト３に支持されてなる。【選択図】図６
