Conventionally, as a polycarbonate resin plate used as a roofing material, a flat plate-shaped plate is mainly used. When an arch-shaped roof as shown in FIG. 9 is formed using such a flat roof material, a rafter (3) is placed on the purlin (2) assembled on the basic steel frame (1). It is constructed by finely assembling to form a grid, and making the roof as a whole an arch shape, and further by assembling a fixed frame made of aluminum or the like on each grid, and inserting a flat roof material (4) into this frame. It is customary.

However, in the above-mentioned conventional PC resin roof, the rafter (3) must be incorporated on the purlin (2), and the fixing frame must be fitted.
There is a problem that these occupy a considerable area on the roof and the lighting rate is reduced. Further, since a lot of labor is required for the work of assembling the rafters (3) and the work of fitting the fixing frame, there is a problem that the work efficiency is lowered and the cost is increased. Furthermore, since the weight of the entire roof will increase due to the rafters (3) and the fixed frame, it is necessary to construct a solid foundation steel frame (1) that can withstand the weight of the roof. Occurs and the cost increases.

Further, since the roof material (10) has a simple shape in which both side edges of the PC resin plate are simply bent, the arch-shaped roof material (10) is formed as in this embodiment. In this case, for example, it can be bent more easily than a PC resin folding plate. Therefore, for example, the radius of curvature can be reduced, and the invention can be applied to a wide range of applications from large buildings to small buildings. Roof material (10)
Since both edges of the roof are bent, the roof material itself can have sufficient strength, for example, the initial roof shape can be maintained for a long time, and damage to the roof material can be reliably prevented.

By the way, the roof material (10) of the present invention has a plate thickness (T) of 1 to 5 mm as shown in FIG. 6, preferably a lower limit of the plate thickness (T) is 2 mm or more and an upper limit. It is better to use a tape having a diameter of 4 mm or less. That is, this plate thickness (T)
If it is too small, sufficient rigidity as a roofing material cannot be secured, and the initial roof shape may not be maintained for a long time, which is not preferable. On the contrary, if the plate thickness (T) is too large, it becomes difficult to form the rising edge portion (11), that is, to bend both side edge portions, and further, bolt penetration work etc. at the time of fixing the rising edge portion (11).
