As shown in Figure 2, there is a gently sloping roof part A on the one-character roof.
It is constructed as a steeply sloping roof section B. The flat roof sheets 5 are cut appropriately at the descending ridge points of the gently sloping roof portion A and the steeply sloping roof portion B, and the gently sloping roof portion A and the steeply sloping roof portion B are descending. They are formed so as to face each other at point A. The gently sloping roof part A and the gently sloping base material 1
The bottom part 4a of the draining material 4 is placed between the lower ridge A side of each of the
(See Figure 3).

Reference numeral 6 denotes a crosspiece, which is formed to be long or of an appropriate length, and is fixed on the support material 3 of the gently sloping base material 1;
At this time, one side in the width direction of the crosspiece 6 protrudes from the receiving material 3 and is configured to cover the end of the gently sloping roof portion A. Also, in the case of the steeply sloping base material 2, the crosspieces 6 are placed along the descending ridge A side on the steeply sloping roof part B, and the end of the steeply sloping roof part B is roofed with nails or the like. It is fixed so as to penetrate through the flat roof plate 5 of.

Regarding the crosspieces 6, there are some differences in thickness between those provided on the gently sloping roof portion A side and those provided on the steeply sloping roof portion B side. The crosspieces 6 are thinner than the crosspieces 6 provided on the side of the steeply sloping roof portion B (see FIG. 3).

A descending ridge wrapping material 7 is placed on these crosspieces 6, 6 and fixed with nails or the like. This descending ridge wrapping material 7
is formed of a long metal plate, with hanging portions 7b, 7b bent from both sides of the mountain-shaped top portion 7a, and holding edges 7c, 7c bent from the lower ends of the hanging portions 7b, 7b. (See Figure 3).
The chevron-shaped top portion 7a or the hanging portions 7b, 7b are fixed to the crosspieces 6, 6 with nails or the like so that the chevron-shaped top portion 7a and the hanging portions 7b, 7b surround the crosspieces 6, 6.

Further, the holding edges 7c, 7c are configured to lightly press onto the gently sloping roof portion A and the steeply sloping roof portion B.

[Effect of idea]

In the present invention, the support material 3 is fixed to the gently sloping roof part A near the descending ridge A of the flat roof where the gently sloping roof part A and the steeply sloping roof part B are adjacent, and the width of the bottom part 4a is A draining material 4 in which a folded edge 4b is bent upward from one side and a rising portion 4c is bent from the other side.
The bottom surface part 4a of the roof part A is provided between the gently sloping roof part A and the gently sloping base material 1, the rising part 4c is aligned with the receiving material 3, the draining material 4 is fixed to the receiving material 3, and the crosspiece 6 is fixed on the receiving material 3, and furthermore, the crosspiece 6 is placed on the descending ridge A of the steeply sloping roof part B and is fixed on the steeply sloped base material 2, so that both the crosspieces 6, 6 are supported. By making the descending ridge wrapping material 7 fixed to the crosspieces 6, 6 to form a descending ridge structure with a flat roof, firstly, rain protection at the descending ridge area can be improved, and secondly, It has a simple configuration and is easy to install.
Thirdly, it has various effects such as making the lower part of the ridge superior in terms of strength.

To explain these effects in detail, the bottom part 4a of the draining material 4, which has a bent edge 4b on one side in the width direction of the bottom part 4a and a rising part 4c on the other side, is connected to the gently sloping roof part A. The draining material 4 is fixed to the receiving material 3 by providing it between the base material 1 and the base material 1 with the rising part 4c along the receiving material 3 fixed near the downward ridge A of the gently sloping base material 1. The bottom part 4a, the folded edge 4b, and the rising part 4c serve as a gutter-like part, and the drainage material 4 is provided along the lower part of the ridge, so that it flows down during strong winds and rain. Even if rainwater flows from the gently sloping roof part A to the eaves A, the gutter-shaped part of the gutter material 4 will receive the rainwater, and the rainwater will flow down from the eaves A to the eaves and be discharged to the outside. Base material 1 gently sloped from the descending ridge A point
Also, it is possible to prevent rainwater from entering the steeply sloped base material 2 side.

In addition, when rainwater flows down along the descending ridge wrapping material 7 and further flows down from the descending ridge wrapping material 7 to the side of the steeply sloping roof portion B, the slope of the steeply sloping roof portion B is large. In addition, the rainwater does not enter the inside of the descending ridge wrapping material 7, that is, it does not flow from the steeply sloping roof part B to the descending ridge A part, and the falling speed is high, and rainwater infiltrates into the steeply sloping base material 2. This is something that can be prevented from happening. Therefore, the gently sloped base material 1
There is an advantage that the structure of the present invention, which provides good rain protection (watertightness), can be made simple by simply providing the drainage material 4 on the steeply sloped base material 2, and there is no need to provide the drainage material 4 on the steeply sloped base material 2. It's summery.

As mentioned above, in the present invention, it is only necessary to provide the draining material 4 on the side of the gently sloping base material 1, and the gently sloping base material 1 is provided with the receiving material 3 and the draining material 4 to which the draining material 4 is fixed. By simply providing a crosspiece 6 to be placed on top and only providing the crosspiece 6 on the steeply sloping base material 2, it becomes an extremely simple structure in which the descending ridge wrapping material 7 is placed and fixed on these crosspieces 6, 6. It is easy to construct,
In turn, construction costs can be reduced.

Next, in the present invention, at the descending ridge part,
A support material 3 and a crosspiece 6 are fixed to the gently sloping base material 1, a crosspiece 6 is fixed to the steeply sloped base material 2, and a descending ridge wrapping material 7 is attached to the support material 3 and the crosspieces 6, 6. Since it is placed and fixed, this downward ridge wrapping material 7
is reinforced from the inside, making it extremely strong.
As a result, the strength and durability of the lower part can be improved.
