PROBLEM TO BE SOLVED: To effectively prevent a connecting part from being damaged by a difference between the temperature of an upper folded plate and that of a lower folded plate, while enabling the fastening of a nut so that the upper and lower folded plates cannot be disconnected from each other. SOLUTION: In this folded-plate roof structure, the nut 16 is screwed to a bolt 15 which is inserted into both an upper fitting 1 fixed to the upper folded plate A and a lower fitting 2 fixed to the lower folded plate B, so that the upper and lower folded plates can be connected together with a vertical space in between; a bolt inserting hole of the upper or lower fitting is formed as a slot 17 long along a folded part D of the folded plate, so that the upper and lower fittings can be assembled in such a manner as to be relatively displaceable in a direction along the folded part of the folded plate; and in a state in which the upper and lower folded plates are connected together by screwing the bolt into the nut, a regulation part 18 capable of regulating the depth of the fastening of the nut to the bolt is provided so that a fastening force cannot act on the fitting wherein the bolt inserting hole is formed as the slot.
