To provide a bolt support unit capable of improving installation workability of a fastener to a bolt, improving installation accuracy, and increasing load bearing capacity.SOLUTION: A bolt support unit 1 includes a bolt 3 having a first male screw part 3a, and a fastener 5 fixed to the bolt 3. The fastener 5 has: an opening/closing sleeve 20 having a body 21 which can be opened and closed in a circumferential direction of the bolt 3, a first female screw part 22 formed on an inner peripheral surface of the body 21, and a connecting surface 23 formed on an outer peripheral surface of the body 21, and capable of engaging the first female screw part 22 with the first male screw part 3a from an intersecting direction X intersecting a screwing direction Y with respect to the first male screw part 3a by closing the body 21 from an opened state; and a fixing member 10 having a fixed inner peripheral surface 11 having a diameter larger than that of the bolt 3, and engaging the first female screw part 22 with the first male screw part 3a to fix the opening/closing sleeve 20 to the bolt 3 by connecting the fixed inner peripheral surface 11 to the connecting surface 23 with the body 21 closed.SELECTED DRAWING: Figure 3
【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ことができ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雄ねじ部３ａを有するボルト３と、ボルト３に固定される止め具５とを備え、止め具５は、ボルト３の周方向に開閉可能な本体２１、本体２１の内周面に形成される第１雌ねじ部２２、本体２１の外周面に形成される結合面２３を有し、本体２１を開いた状態から閉じることにより、第１雄ねじ部３ａに対する螺進方向Ｙと交差する交差方向Ｘから第１雌ねじ部２２を第１雄ねじ部３ａに係合可能な開閉スリーブ２０と、ボルト３よりも大径の固定内周面１１を有し、本体２１が閉じた状態で固定内周面１１を結合面２３に結合することにより、第１雌ねじ部２２を第１雄ねじ部３ａに係合して開閉スリーブ２０をボルト３に固定する固定部材１０とを有する。【選択図】図３
