PURPOSE:To simplify work by providing a ceiling surface with frame bodies in the shape of a lattice through spaces, providing crossed sections, having the crossed spaces between the frame bodies, with service units, and setting service plates having a plurality of holes, and by arranging ceiling plates in the frame bodies. CONSTITUTION:On a ceiling surface, channels 1 are suspended, and are arranged at specified intervals with bolts 2 and hangers 3, and on the channels 1, in the direction crossed over the channels 1, channels 5 are fixed with fixing devices 4. Besides, in the directions crossed over the channels 1, T-bars 6 are fixed on the lower sides of the channels 1 with clips 7, and on the channels 5, in the directions crossed over the channels 5, T-bars 8 are fixed with hangers 9, and frame bodies 10 are formed. Then, the frame bodies 10 are arranged in the shape of a lattice through spaces on the ceiling surface, and between the T-bars 6, H type bars 12 are erected, and between the bars 6, 12, ceiling plates 13 are laid. Besides, a sprinkler pipe 21, a speaker 22, an emergency lamp 23, a fire-sensitive device 24, and the like are arranged, and a cross-type equipment plate 15 having a plurality of holes 16 is set at the crossed sections 4 of the bars 6, 8. |
