PROBLEM TO BE SOLVED: To provide a joist support hanger that has a hanging bolt fixing part 31 and a joist support part 32 rotatably pivoted to enable angular adjustment to suit a ceiling panel 6 installed in a horizontal position or at a prescribed angle of inclination, the joist support hanger further including a screw hole that overlaps at any angular position drilled in a wide screw hole formation area T set on an outer peripheral surface area around an axis of the rotatable pivot opposite the hanging bolt fixing part, in a preliminary step in which a joist support hanger 3 is fitted to a hanging bolt 2, as well as connecting pieces 312 and 322 mutually fixed with a screw, for integrating the hanging bolt fixing part and the joist support part integrated in a rotation regulated state.SOLUTION: The hanging bolt fixing part 31 and the joist support part 32 are integrated in a rotation regulated state, by fixing overlapped screw holes S1 and S2 with a screw to each other, the screw holes having been drilled in the screw hole formation area T while the hanging bolt fixing part and the joist support part are aligned at a prescribed angle. A joist support 4 is configured to be supportable, with an undersurface thereof in a surface-contact with a bottom surface piece of a U-shaped part 321.SELECTED DRAWING: Figure 1 |
