PURPOSE:To promote close dimensional tolerances in a frame work of ceiling bars, to promote face rigidity and to reduce a number of execution processes. CONSTITUTION:Cross-shaped coupling metal fixtures 5 are suspended by suspension metal fixtures 4 mounted to hanger bolts 3 suspended from a ceiling slab 1. An intermediate section of the adjoing first ceiling bar 61 is held by the coupling metal fixtures 5 and, at the same time, a second ceiling bar 62 is held at a right angle. In the same way, a third ceiling bar 63 is held at a right angle by the coupling metal fixtures 5 holding the intermediate section of the second ceiling bar 62, a fourth ceiling bar 64 is held at a right angle by the coupling metal fixtures 5 holding the intermediate section of the third ceiling bar 63, and the first ceiling bar 61 is held at a right angle by the coupling metal fixtures 5 holding the intermediate section of the fourth ceiling bar 64 to form a ceiling panel building square space 7 in the same plane. According to the constitution, the ceiling bars 61-64 can continuously arrange a plurality of square spaces 7 in the same plane on the basis of the square space 7 as one of the sides of the adjoing square space 7. |
