  Inside the pair of roof frames 2, 2, a guide portion 3 having a pair of support materials 31, 31 and a field plate 32 as a base plate is provided.

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

  A support member 31 having an L-shaped cross-sectional view is attached along the inner surface of the web 22 of the roof frame 2. The support material 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 material 4. In FIG. 2, the support member 31 is formed in a shape that extends over substantially the entire length of the roof frame 2, but is divided into a plurality of portions so as to support only a plurality of positions in the longitudinal direction of the field plate 32. Can also be used.

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

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

The reinforcing member 72 and the mounting bracket 73 can be integrated into the mounting member F, and the number of parts and the number of mounting steps to the roof frame 2 can be reduced. Moreover, in the said embodiment, although it is set as the attachment metal fitting 73 of the side view substantially reverse ohm shape which has the 1st, 2nd flange parts 73a and 73b and the side-view U-shaped accommodation part 73d, it is limited to this structure. It never happens. The first and second flange portions may be a mounting bracket 73 having a simpler configuration as a side-view crank shape including the flange portions 73a and 73b.

  In addition, a reinforcing member 72 made of a frame material having a U-shape in cross-sectional view (C-shape) is used as the mounting frame, but two side walls 72c are provided using a square steel pipe having a cross-sectional view in a U-shape. The load resistance can be further improved. As a result, the load resistance of the parapet cover lid 71 and the drainage structure 6 supported by the mounting frame can be further improved. In any case, a difference in height can be provided between the upper wall 72a to which the eaves-end side connecting portion 76 is fixed and the lower wall 72b to be fixed to the mounting bracket 73, so that the degree of freedom of component mounting is increased. improves. Note that the mounting frame is not limited to a U-shaped frame shape or a U-shaped frame material, and a frame material such as a T shape, an L shape, an I shape, or an Ω shape in a side view, or a flat plate can be used.
