ROOF STRUCTURE

PROBLEM TO BE SOLVED: To provide a roof structure excellent in workability and excellent in waterproofness.SOLUTION: A first folded plate 1a has a first overlapping part 10 formed at an end part on the side of a second folded plate 1b. The second folded plate 1b has a second overlapping part 20 formed at an end part on the side of the first folded plate 1a. The second overlapping part 20 overlaps the first overlapping part 10 and a crest part 40 protruding upward is formed by the first overlapping part 10 and the second overlapping part 20. The first overlapping part 10 includes a one engaging part 14 positioned closer to the first folded plate 1a than the apex part 44 of the ridge part 40, and another engaging part 15 located closer to the second folded plate 1b side than the apical part 44. The second overlapping part 20 has one engaged part 24 engaged with the one engaging part 14 and the other engaged part 25 engaged with the other engaging part 15. The one engaged part 24 is caulked and fixed to the one engaging part 14 and the other engaged part 25 is caulked and fixed to the other engaging part 15.SELECTED DRAWING: Figure 1 【課題】施工性に優れ、かつ防水性に優れた屋根構造を提供する。【解決手段】第１折板１ａは、第２折板１ｂ側の端部に形成された第１重なり部１０を有している。第２折板１ｂは、第１折板１ａ側の端部に形成された第２重なり部２０を有している。第２重なり部２０が第１重なり部１０の上に重なり、第１重なり部１０と第２重なり部２０とで上方に突出した山部４０が形成されている。第１重なり部１０は、山部４０の頂部４４よりも第１折板１ａ側に位置する一方係合部１４と、頂部４４よりも第２折板１ｂ側に位置する他方係合部１５とを有している。第２重なり部２０は、一方係合部１４に係合された一方被係合部２４と、他方係合部１５に係合された他方被係合部２５とを有している。一方被係合部２４が一方係合部１４にかしめ固定されている。他方被係合部２５が他方係合部１５にかしめ固定されている。【選択図】図１
