PURPOSE: To prevent a ceiling panel from hanging down because of its own weight and thereby producing a sense of pressure and degrading appearance. CONSTITUTION: Bolt holes in a connecting member 6 are so formed that the bolt holes 6x2 are located above the bolt hole 6x1 at each end of the member 6, while bolt holes 51 a in the flange 51 of each ceiling panel unit 5A are so formed that their centers are located on a horizontal line L. When time ceiling panel units 5A are connected along with the connecting member 6, the ends of the ceiling panel units 5A at the flanges 51 form an upwardly projecting curved surface along the bolt holes in the connecting member 6. |
