PROBLEM TO BE SOLVED: To mount floors formed into blocks easily, to reduce the cost of construction, and to shorten construction term. SOLUTION: In this method for constructing floors at a plurality of stories for a boiler cage section, the floor 13A at one story is assembled on a lifting frame 18 installed on the ground, is lifted by a jack 14 per lifting frame 18, and is mounted on a set story, and then the lifting frame 18 separated from the floor 13A is lowered by the jack and is returned on the ground. By repeating a series of these processes, a plurality of floors are sequentially constructed from the uppermost story toward the lowermost story. COPYRIGHT: (C)2008,JPO&INPIT |
