As shown in FIG. 3, the roof frame 2 connects the wide lower flange 21 and the narrower upper flange 23, and the side edges of the lower flange 21 and the upper flange 23 arranged in parallel. It is formed in a substantially U-shape (C-shape) in cross-sectional view by the web 22 and the like.

A support member 31 having an L-shaped cross section is attached along the inner surface of the web 22 of the roof frame 2. The support member 31 is attached to the inside of the roof frames 2 and 2 in accordance with the gradient formed on the upper surface of the roofing member 4. Although the support member 31 is shown in FIG. 2 in a shape extending over substantially the entire length of the roof frame 2, it is divided into a plurality of support members 31 so as to support only a plurality of locations in the longitudinal direction of the field plate 32. You can also use the one.

As shown in FIG. 3, both side edges of the field plate 32 are placed on the support members 31 and 31 attached to the inner side surfaces of the roof frames 2 and 2, respectively. Since the field board 32 is formed to have a constant thickness, the upper surface of the field board 32 has the same slope (roof slope) as the slopes of the support members 31 and 31.

The field plate 32 is connected to the support member 31 by a fixing member such as a screw. Further, the upper surface of the field plate 32 is covered with a waterproof sheet 32a such as polyethylene roofing. As shown by the broken line in FIG. 3, the waterproof sheet 32a is laid up to a position on the inner side surface of the roof frame 2. Therefore, the entire surface of the field board 32 is covered with the waterproof sheet 32a, and the waterproof property is ensured.
