PROBLEM TO BE SOLVED: To improve construction efficiency for a large roof panel, by longitudinally and transversely joining a plurality of roof panels each having a rectangular shape in a plan view, for forming the large roof panel, and joining the roof panels so that a side joint line of the longitudinally adjacent roof panels is discontinuous from a side joint line of the other panels. SOLUTION: Joining of roof panels 2a to 2f forming a large roof panel 1 is fixed by clamping by means of roof clamping bolts, or by slant driving by means of screw spikes. In the large roof panel 1, a longitudinal joint line Y1 between the transversely adjacent roof panels 2a, 2b, and 2c, 2d is rendered sequential, while a side joint line X1 between the longitudinally adjacent roof panels, is rendered discontinuous from a side joint line X2 between the same. Further, a side joint line X3 between the roof panels 2e, 2f is aligned with an extension of the side joint line X1, and the side joint lines X1, X3 on the same line are positioned on girder member of an external wall and a main house upper portion, which constitute a skeleton of a building. Therefore, a roof structure which is easily constructed at a low cost can be formed. |
