PROBLEM TO BE SOLVED: To provide a fixture for a hanging bolt that enhances rigidity strength of fitting by treating a lower surface fixing part 21, a side surface fixing part 22 and a hanging bolt fixing part 23 as an integral structure, the lower surface and side surface fixing parts being surface-abutted to a lower surface part and a side surface part on a non-open side of C-shaped steels 11, 12, allows a screwing surface of the hanging bolt fixing part 23 to be disposed in parallel with a ceiling panel side all the time for vertically fixing the hanging bolt fixing part while keeping a hanging bolt in a vertical position, firmly receives a vibration load with the two fixed surfaces and prevents sliding, separation, cluttering and displacement, thereby enhancing seismic resistance.SOLUTION: Hanging bolt fixtures 2a, 2b are configured with a lower surface fixing part 21 and a lower surface fixing part 22 surface-abutted and fixed on a lower surface part and a side surface part of C-shaped steels 11, 12, and a hanging bolt fixing part 23 on which a hanging bolt 3 is screwed. The hanging bolt fixing part 23 is pivoted on the lower surface fixing part 21 in a way that allows angle adjustment, so that a screwing surface of the hanging bolt 3 may be disposed in parallel with a ceiling panel side.SELECTED DRAWING: Figure 1 |
