In summary, even if the insulating material is melted or softened due to a fire or the like, the fixing device of the present invention prevents the support portion from falling and the holding portion from moving the bolt rod. The position of the part hardly changes, and the bolt rod does not move up and down as it is. Therefore, the second folded roof is stably supported, and there is no danger of falling or becoming unstable. Further, the first folded roof portion and the second folded roof portion are firmly connected by the above-mentioned fixing device, and when the construction work is performed, the folded roof plate and the fixing device of the second folded roof portion are rotated. Since there is no need to use a simple fitting method, not only the workability is significantly improved, but also various members and components are not forcibly bent, so that they are not damaged or broken. Further, since the insulating material is not in direct contact with the leg frame portion and the receiving portion or is in a non-contact state, heat conduction is reliably prevented in both folded roof portions, so that a heat bridge does not occur, and Since the leg frame portion and the receiving portion are integrally formed by the rod, it is possible to reliably receive a positive load or a load applied to the fixture, and to sufficiently withstand long-term use.
