PURPOSE:To simplify construction, to increase the degree of accuracy of size in connection of ceiling bars, to promote face-rigidity and, at the same time, to reduce a number of construction processes. CONSTITUTION:Angle controlling holding sections 13 extended in a cross direction of the same plane are formed in a cross-shaped coupling metal fixture 5 suspended with a suspending metal fixture 4 mounted to a hanger bolt 3 suspended from a ceiling slab 1. A pair of holding pieces 15 holding a ceiling bars 6 are formed in the holding sections 13 and, at the same time, a holding claw 14 interlocking and holding the ceiling bars 6 are formed. The ceiling bars 6 are held and fixed by screwing clamping screw into & bar rings 19 having mounting screw holes provided to the holding sections 13 to bring the clamping screws 18 into contact with the upper surface of the ceiling bar 6. |
