<P>PROBLEM TO BE SOLVED: To easily increase the external appearance of the ceiling surface by forming a camber on a ceiling board and adjusting the camber. <P>SOLUTION: One end sections 2a of a plurality of ceiling boards 2 are fixed to both side walls of a ceiling forming space 1, the other end sections 2b of both ceiling boards 2 are respectively mounted to a middle part of the ceiling forming space 1 in a height adjustable manner, and the central pats of both ceiling boards 2 are respectively mounted to a height adjustable ceiling board central mounting section A provided to a middle position between a ceiling board end mounting section C and a central ceiling board end mounting section B. The ceiling board 2 is curved upward to form the camber so that the central part of the ceiling board 2 can become higher than both end sections 2a and 2b by adjusting the height of the ceiling boar central mounting section A. Then, the ceiling board 2 is further curved to adjust the camber so that the other end section 2b of the ceiling board 2 can become higher than the central part by adjusting the height of the central ceiling board end mounting section B. <P>COPYRIGHT: (C)2004,JPO |
