PURPOSE:To perform a precise construction so as to cause no difference in level, and simplify the construction. CONSTITUTION:A frame body 2 for emphasizing a ceiling design is installed along the periphery of a rectangular ceiling plate 1, the ceiling plate 1 is fitted to each section of a ceiling support bar 5 integrated into the ceiling part in lattice, and the ceiling plate 1 is supported by the ceiling support bar 5. Mounting plates 3 are installed to near one-side end parts of four sides of the frame body 2 so as to be partially protruded from the frame body 2, respectively. A mounting screw 6 is inserted through a mounting hole 4 provided on the part protruded from the frame body 2 of the mounting plate 3 from under. Each mounting plate 3 is independently brought into contact with the lower surface of a hanging hook 7 installed to the ceiling support bar 5, and the mounting screw 6 is screwed to the hanging hook 7 through the mounting hole 4. |
