<P>PROBLEM TO BE SOLVED: To form a ceiling which is made structurally fireproof without undergoing a process of hanging the ceiling from a building frame, even if a ceiling panel cannot be vertically dropped in. <P>SOLUTION: Guide materials 4 are provided on a pair of two opposed side parts of four side parts of a ceiling panel body 1a, and a lamella board 5 is provided at a side edge of either of the two paired side parts. Next, the body 1a is hung in such a manner that one side part, which is provided with the lamella board 5, is inclined downward. After that, the lamella board 5 is brought into close contact with a lower-part-of-wall plaster board 7 which is provided under beam receiving plywood 8 of a wall surface of a wall panel 6a, and the guide materials 4 are placed on an upper end of the board 7. Subsequently, the side part facing one side part is moved downward, so that side edges, on the three other side parts, of a ceiling plaster board 3 can be brought into close contact with the board 7 and so that guide materials 5, which are provided on the three other side parts, can be placed on the upper end of the board 7. <P>COPYRIGHT: (C)2003,JPO |
