Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 and FIG. 2 show a sheet metal descending ridge member 1 of the present invention. A main body 2 made of a polyvinyl chloride steel plate having an engaging portion 2a formed thereon, two sealing members 3, 3 disposed on the back surface of the main body 2 toward the flow direction of the building K, and It is composed of a sealing material 4 disposed in the left / right direction of the exit building K.

As a result, as described later, the sheet metal descending ridge member 1 straddles between the left and right flat roof members 10L and 10R fixed along the descending ridge K of the roof, and covers the butted portions at the same time. The engaging portions 2a are left and right flat roof members 1
0L and 10R are engaged with the tip corners, and the sealing members 3 and 3 are in close contact with the surfaces of the left and right flat roof members 10L and 10R fixed along the descending ridge K, and the sealing member 4 is a sheet metal. The left and right flat roof members 10L and 10R which are fixed by being overlapped above the descending ridge member 1 are brought into close contact with the back surface front portions. Therefore, since the sheet metal descending ridge member 1 is integrated with the left and right flat roof members 10L and 10R, the wind resistance is improved. Rainwater that tends to enter the flow of the descending ridge K can be waterproofed by the seal members 3, 3 and 4 of the sheet metal descending ridge member 1, respectively.

When such a sheet metal descending ridge member 1 is to be attached to the descending ridge K, first, a flat roof material 10 is placed on the eaves of the roof, and nails n are driven into its base to be fixed to the roof (see FIG. 3). ). The left and right flat roofing materials 10L and 10R fixed along the exit building K have their side edges cut off along the exit building K. Then, the sheet metal descending ridge member 1 is placed across the left and right flat roof members 10L and 10R fixed along the descending ridge K, and their butted portions are shielded. Then, by pulling up the sheet metal descending ridge member 1 in a direction opposite to the flow direction of the descending ridge K, the engaging portion 2a formed at the tip of the member 1 is lifted to the left and right flat roof members 10L, 10L.
Then, a nail n is driven into the base of the sheet metal descending ridge member 1 to be fixed to the roof (see FIG. 4).

As a result, the sealing members 3, 3 of the sheet metal descending ridge member 1 come into close contact with the surfaces of the left and right flat roof members 10L, 10R fixed along the descending ridge K, respectively.

Next, a part of the flat roofing material 10 fixed to the eave is partially overlapped with the base, and the next flat roofing material 10 is fixed to the roof. At this time, the right and left flat roof members 10L and 10R of the next stage fixed along the descending ridge K have their back surface tips in close contact with the sealing material 4 of the sheet metal descending ridge member 1. After this, get off building K
10L of these left and right flat roofing materials fixed along
The next-stage sheet metal descending ridge member 1 is placed and pulled up so as to shield the butting portion of the 10R, so that the engaging portion 2a formed at the tip thereof is moved to the next-stage left and right flat roof members 10L,
10R is engaged with the tip corner, and its base is fixed by driving a nail n. Hereinafter, the flat roof material 10 and the sheet metal descending ridge member 1 may be similarly fixed.

In this case, the nails n for fixing the sheet metal descending ridge member 1 are concealed by the left and right flat roof members 10L and 10R, so that no nail marks are exposed on the roof surface.
A roof with a clean appearance can be formed.

Since the flat roof material 10 and the sheet metal descending ridge member 1 are fixed in this way, it is possible to prevent rainwater from entering the descending ridge K, and at the same time, the sheet metal descending ridge member 1 and the flat metal roof member 10 are fixed. It is integrated and can surely prevent peeling by wind.
