PURPOSE:To facilitate the installation of equipment and a ceiling panel and facilitate the maintenance and inspection of the equipment. CONSTITUTION:A width producing material is connected between two finished materials, thereby forming a plurality of equipment lines for equipment mounting in the longitudinal direction. Joining members 2 are connected to each other crosswise, thereby forming a rectangular space 3. A plurality of ceiling panels 10A and 10b are installed in the rectangular space 3. The first ceiling panel 10A at least on the equipment line side is rotatively engaged in the vertical direction. This constitution makes it possible to block an equipment mounting area and a ceiling panel installation area linearly, thereby facilitating the installation of the equipment and the first ceiling panel 10A and the second ceiling panel 10B. It is also possible to replace and inspect the equipment by rotating the ceiling panel 10A on the equipment line side. |
