- A plurality of water guide plates n are attached along the vertical direction to the outer and inner surfaces of the second vertical members/9 arranged in rows.

The water guide plate n is a long plate-like member along the ridge direction.

The cross section in the transverse direction is formed by bending the end edge and forming the first inclined part 2.
3, and near the center in the transverse direction, the first
A second inclined part 23B is formed by bending the inclined part 23A in a direction away from the inclined direction, and a first flat part 230 is formed between the first inclined part 23 and the second inclined part 23B. A second plane part 2JD parallel to the first plane part 230 by bending the second inclined part JIB in the opposite direction to the first plane part λ3C
, and further bend the end edge of the second plane part λ3D in a direction away from the inclination direction of the second inclined part 23B on the same side as the second inclined part JJ]3 to form a third inclined part 23I. It has a shape formed by forming. Then, with the first slope part 23 positioned upward and the third slope part 23K positioned downward, the second plane part -3D is brought into close contact with the inner and outer surfaces of the second vertical member 19 to form the water guide plate n. A plurality of water guide plates n are attached to the second vertical member l, and the third inclined part 23B of the upper water guide plate n and the first inclined part 23 of the immediately lower water guide plate n face each other. along the vertical direction a second vertical member l? Arrange in.

A long waterproof sheet, such as a rubber sheet J, is attached to the lower end of the inner surface of the second vertical member 9 along the ridge direction. The lower end of the rubber sheet 211 is hung over the main roof board or water return board 2j, and the upper end of the rubber sheet is placed between the inner surface of the second vertical member 9 and the inside of the second vertical member 1. The rubber sheet plate is attached to the second vertical member 1 so as to be sandwiched between the lowest water guide plate 3 of the water guide plates n arranged on the side. Therefore, even if rainwater infiltrates into the pair of water guide plates n attached to the second vertical member /q so as to face each other with this in between, the rainwater will flow down the second vertical member /9. Then, it will flow down onto the main roof board 9 guided by the rubber sheet.

Said water return board 2! In this method, the actual roof board 9 is bent and used. A main roof board with a water return plate 2 attached to one end A of the chevron-shaped cross section of the top main roof board in the roof inclination direction among the main roof boards 9 arranged on the upper surface of the second base material t. The second base material t extends to the center of the main roof board 9, which has a hook-shaped cross section and is used as the water return part 20.
The water return plate 2j is placed along the upper surface, then the central portion is bent upward to stand up, and the rising portion is placed along the outer surface of the first ventilation ridge support 10 or the second ventilation ridge support 10h. Arrange. Therefore, even if rainwater intrudes into the ventilation building λ, the water return plate 2j
This will prevent rainwater from penetrating indoors.

Since the ventilation ridge structure is configured as described above, the indoor air and the air between the first base material T and the second base material T are
The air inside the ventilation ridge λ rises into the ventilation ridge λ, and then passes through the gaps between the first vertical member 13, the second vertical member 19, and the water guide plate n arranged in the array, and goes out to the outdoors. Ventilation can be achieved.

In the case of rain, even if rainwater falls into the water guide plate 3, the second slope part 23B1 second plane part recognition third slope part 23B
The rainwater flows down and falls onto the water guide plate 3 located below, and in this way, the rainwater flows down the arranged water guide plates one after another, and finally passes through the rubber sheet and falls onto the main roof plate 9. Rainwater flowing out and falling is prevented from entering the ventilation building λ. Moreover, even if rainwater intrudes into the ventilation building λ, the water return plate 25 can prevent the rainwater from infiltrating indoors.

By changing the attachment positions of the first ventilation ridge support 10 and the second ventilation ridge support IOA to the support member S, the inclination angle of the ventilation ridge roof can be varied. For example, the first ventilation ridge support 10 and the second ventilation ridge support /□A are erected corresponding to the bolt attachment hole closest to the upper end of the support member 5 in the inclination direction among the plurality of bolt installation holes 〇 in the support member S. When installed, the interval between the first ventilation ridge support IO and the second ventilation ridge support IOA becomes the narrowest, and the ventilation ridge roof can be made to have a steep slope. Moreover, if the first ventilation ridge support IO and the second ventilation ridge IOA are erected corresponding to the bolt attachment hole 5D that is farthest from the upper end in the inclination direction of the support member 3 among the plurality of bolt attachment holes jD in the support member 3, The interval between the first ventilation ridge support io and the second ventilation ridge support 10A is the widest, and the ventilation ridge roof can be made to have a gentle slope.

Since the steeply sloping ventilation ridge roof is suitable for polyglot and heavy rain areas, the ventilation ridge structure of the above embodiment can be used for both polyglot and heavy rain areas and other areas.

Since each member constituting the ventilation ridge structure in the above embodiment can be mass-produced in a factory, the ventilation ridge structure can be easily manufactured by assembling the members mass-produced in the factory on site.

Although one embodiment of this invention has been described in detail above, this invention is not limited to the above embodiment, and it goes without saying that it can be implemented with appropriate modifications within the scope of the gist of this invention. Nor.

Instead of attaching the water guide plate 3 to the second vertical member 19 as in the previous embodiment, a water guide plate n may be attached to the second vertical member as shown in FIG.

That is, the water guide plate n shown in FIG. 3 has the same shape as the water guide plate force in the previous embodiment. and a third slope part, 2
The water guide plate 3 is attached to the outer surface of the second vertical member 19 such that 7E is located upward and the first inclined part 23A is located downward, and the first inclined part 23A of the upper water guide plate 3 and the lower part are connected to each other. A plurality of water guide plates 3 are arranged on the outer surface of the second vertical member 1 so that the third inclined portions 23B of the water guide plates 3 face each other. Note that the water guide plate 3 on the inner surface of the second vertical member 19
The manner of attachment and arrangement of the is the same as in the previous embodiment.

If the water guide plate 3 is installed and arranged as shown in FIG. This is convenient because it becomes easier to fall onto the roof board 9.

As detailed above, according to the present invention, a strongly formed ventilation building can reliably prevent rain leakage and can be easily manufactured by assembling parts that can be mass-produced in a factory on-site. structure can be provided. Further, in the ventilation ridge structure according to the present invention, since the roof slope of the ventilation ridge can be set at the time of construction according to the slope of the roof to be constructed, the harmony of the entire roof is not impaired.
