PROBLEM TO BE SOLVED: To provide a system ceiling in which an equipment plate for mounting of equipment component is constructed in a small size without using any suspension bolt or reinforcing member by installing the equipment plate at the intersection of a pair of ceiling supporting bars. SOLUTION: A pair of ceiling supporting bars 1a, 1a are installed in lattice form in the ceiling space, and a ceiling plate 3 is supported in the space of these ceiling supporting bars 1a, 1a so that a ceiling is completed. A cut part 4 is formed at the corner of the ceiling plate 3 mating with that intersection of the pair of ceiling supporting bars 1a in a position where the equipment component 5 is placed. In this part, an equipment plate 2 in the form of a right angled triangle is installed, and its two edge members embracing the right angle are placed on and held by the ceiling supporting bars 1a. This allows constructing the equipment plate 2 in a small size, does not degrade the design excellency, manages with a small cut 4, and facilitates execution of works. |
