PROBLEM TO BE SOLVED: To provide a reinforcing structure of a folded plate roof preventing deformation such as flexure of the folded plate roof even if reinforcing members are independently provided. SOLUTION: A roof structure using a folded plate 3 with crest parts 1 and trough parts 2 alternately formed to extend in parallel with each other is provided with the long-sized reinforcing member 5 extending along the trough part 2 while straddling the adjacent crest parts 1 of the folded plate 3. A beam form 8 of approximately square cross section is formed by the reinforcing member 5 and a recess 7 of the folded plate 3 formed between the adjacent crest parts 1 of the folded plate 3 via the trough part 2, and the folded plate roof is reinforced by the beam form 8. The reinforcing member 5 is fixed in an unmovable manner to the folded plate 3. COPYRIGHT: (C)2007,JPO&INPIT
