Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a ventilation system for ventilating an attic or the like.

[Background technology]

Conventionally, as a ventilation system for ventilating the attic, a ventilation hole is installed in the roof of the building, and this ventilation hole is covered with a cover such as a ventilation tube, ridge decoration, or roof overhang, and a ventilation window is opened at the position facing the cover. Some ventilate the attic through ventilation windows, covers, and vents. However, the structure of the cover is to assemble a wooden frame and then attach exterior materials, or to construct a steel frame and then attach panels with exterior materials, both of which require a structural framework and require on-site construction. was complicated.

[Purpose of the invention]

An object of the present invention is to provide a ventilation system that can be easily installed on site.

[Disclosure of the invention]

Similarly, the ventilation section girder side wall panel 16a and the ventilation section girder side wall panel 16c are connected to the gable side frame 14.
b and the girder side frame 14d and fixed. Note that a ventilation window 24 formed by cutting out the exterior material 20b is also formed in the ventilation section end side wall panel 16b.

As shown in FIG. 13, the ventilation box 72 is inserted and fixed into the ventilation windows 22, 24 of the ventilation section end side wall panels 16a, 16c. ventilation box 72
A pair of side end surfaces 74 and 76 facing each other are open, a mesh 78 is attached to the side end surfaces 74 and 76, and an opening 82 is formed in the center of the upper surface 80.

As shown in FIG. 14, the ventilation room root panel 26 is installed by placing the outer peripheral edge on the upper surfaces of the ventilation section girder side wall panels 16a, 16b and the ventilation section girder side wall panels 16c, 16d and securing them with screws. .

As shown in FIG. 15, the ventilation section girder side wall panels 16a, 16b and the ventilation section girder side wall panels 16
A sealing agent 84 is filled in each of the connecting portions c and 16d.

As shown in FIG. 1, the ventilation windows 22 and 24 are covered with louvers 86 and 88 to complete the ventilation system.

The attic is ventilated as follows. That is, the outside air that has entered the steam box 72 through the ventilation windows 22 and 24 enters the attic through the opening 82 and the ventilation opening 12. In addition, when there is no wind, the warm air in the attic flows from the ventilation port 12 to the opening 82.
→ Ventilation box 72 → Exhaust to the outside through ventilation windows 22, 24. In this way, the attic is naturally ventilated.

According to the ventilation system configured in this way, the ventilation section girder side wall panels 16a, 16b and the ventilation section girder side wall panels 16c, 16d are arranged in the panel frame 1, respectively.
Exterior materials 20a to 20d are attached to the outer surfaces of 8a to 18d, and the panels are formed into panels. These paneled ventilation section gable side wall panels 16a, 16b
And the ventilation section girder side wall panels 16c, 16d are simply connected to the girder side frames 14a, 14b and the girder side frames 14c,
It is sufficient to simply place and fix the structure on 14d, eliminating the need for a conventional structural framework, and making it easier to construct on-site.

In addition, the lower ends of the exterior materials 20a to 20d of the ventilation part girder side wall panels 16a and 16b and the ventilation part girder side wall panels 16c and 16d are connected to the panel frames 18a to 18d.
8d protrudes downward from the lower end of the girder side flashing covers 60, 62 and the girder side flashing covers 64,
66, the lower ends of the ventilation section girder side wall panels 16a, 16b and the ventilation section girder side wall panels 16c, 16d can be easily sheltered from rain. Also, first place the frame 14 on the roof 10.
Since it is installed on the top surface, the rain flashing base plates 42, 44, drainage ditches 46, 48, gable side flashing covers 60, 62, girder side flashing covers 6 are installed on the outer periphery of the frame 14.
4, 66 can be installed to easily provide rain protection between the roof 10 and the roof 10.

Furthermore, by adjusting the height dimension of the frame 14, tiles 54 such as asbestos straight tiles, S tiles, Japanese tiles, etc.
can respond to changes in thickness.

In the above embodiment, a ventilation tube type was used, but a ridge decoration, an overhanging roof, etc. may also be used.

〔Effect of the invention〕

According to the ventilation system of the present invention, a pedestal is provided on the upper surface of the roof surrounding the ventilation opening, a ventilation section wall panel is erected on the mount, and a ventilation room root panel is attached to the ventilation section wall panel, The ventilation section wall panel is made into a panel, so it can be simply placed on a frame and fixed, eliminating the need for a structural framework and facilitating on-site construction. In addition, by fixing the pedestal placed on the roof with angle fittings, it is possible to easily prevent rain from intervening with the roof. Furthermore, since this angle metal fitting is provided on the inner periphery of the pedestal, there is an advantage that it does not become a hindrance when applying rain cover to the outer periphery.
