Description

[Detailed Description of the Invention] The present invention relates to an attic ventilation system installed in an opening in the gable side wall of a building.

Conventionally, this type of ventilation system has been used with a synthetic resin or wooden ventilation frame having slits in the openings mentioned above, but for users, that is, residents, it feels artificial. There is a strong demand for wooden products made from natural wood, which has been familiar since ancient times, rather than synthetic resin products.

However, even if a ventilation frame is made of not only wood but also synthetic resin, it will burn down or melt instantly in the event of a fire, and the wide opening can become an entry point for the fire to enter the attic, increasing the disaster. There was a problem.

In view of these problems, the purpose of this invention is to provide an arrow-cut ventilation system that can prevent fire from entering as much as possible in the event of a fire, while making use of the material of wood, which is widely preferred by the general public. It was created as a.

In order to achieve such a purpose, in this invention, the ventilation opening 3 provided on the gable side wall of the building is covered with an iron plate 5 having a slit 8 that communicates between the inside and the outside. A wooden decorative frame 1 equipped with an inclined slit 16 that rises toward the
3 is attached to form a ventilation passage passing from the slit 16 of the decorative frame 12 to the slit 8 of the iron plate 5, and the bent part 6 whose upper surface faces outward and descends in an inclined manner is attached to the iron plate 5. The decorative frame 12 is provided continuously at the lower end portion, and the lower end portion of the decorative frame 12 is disposed above the bent portion 6.

The structure of the present invention will be explained below based on drawings showing one embodiment. In Fig. 1, an arrow board 1 made of plywood or the like constituting a wall surface is attached to a truss on the gable side of a building. A ventilation hole 3 having a pentagonal roof shape matching the shape of the top of the roof 2 is opened in the plate 1. 4 is the gable base plate on the upper gable side.

On the other hand, 5 is a ventilation iron plate formed into a similar pentagonal shape to match the ventilation opening 3, and whose lower end is bent outward into a U-shape 6, and both left and right ends are bent outward into an L-shape 7. The iron plate 5 is attached to the ventilation port 3, covers the ventilation port 3, and has a slit 8 in its center that communicates with the inside and outside.
It is configured to ventilate the attic through this slit 8. After the ventilation iron plate 5 is installed, a gable iron plate 9 is attached to the upper surface of the gable base plate 4, and the lower end 10 of this gable iron plate 9 presses down the end of the ventilation iron plate 5. 11 is the Oni board.

Next, reference numeral 12 shown in FIG. 2 is a wooden decorative frame, which includes a surrounding frame 13 formed into a roof-shaped pentagon like the ventilation opening 3, and a frame 13 extending from side to side inside the surrounding frame 13. As shown in Figure 4, it consists of a large number of horizontal bars 14 that are in close contact with each other, and among these horizontal bars 14...
The four pieces slightly below the center are marked with figures 3 and 4.
As shown in the figure, the lower edge is cut out 15, and an inclined slit 16 rises from the outside to the inside.
are formed in multiple numbers. The decorative frame 12 thus formed is attached to the outside of the iron plate 5 to which the ventilation opening 3 is attached, covering the iron plate 5 and communicating the slit 16 of the iron plate 5 with the slit 8 of the iron plate 5. , these slits 8, 16
The attic is ventilated through the attic.

In addition, 17 shown in FIGS. 2, 3, and 5
is a siding material attached to the outer surface of the arrow board 1 as a surface material.

Further, below the iron plate 5 and the decorative frame 12, the upper end portions of the double siding materials 17, 17 attached to the outer surface of the arrow board 1 are connected to the lower end portion of the iron plate 5. It is covered by the glyph 6. Note that the upper surface of this U-shaped portion 6 is
As shown in FIG. 5, the tip edge, which is inclined outward and bent inward in a substantially horizontal state, is in contact with the outer wall surface of the outer sanding material 17. As shown in FIGS. 2 and 3, above this U-shaped portion 6, the lower end portion of the surrounding frame 13 of the decorative frame 12 is arranged. That is, for example, due to wind and rain blowing onto the decorative frame 12, the decorative frame 12 and the iron plate 5 may be damaged.
Even if rainwater or the like gets into the space between the two, it will be easily drained out through the upper surface of the U-shaped part 6.
This has the advantage that corrosion of the iron plate 5 is prevented and durability is improved.

In addition, in the above, the method of attaching the ventilation iron plate 5 and the decorative frame 12 may be any method.

The present invention has the above-mentioned structure, and as described above, the present invention has a double structure consisting of a ventilation iron plate provided at the ventilation opening and a decorative frame provided on the outside of this ventilation iron plate. Therefore, even if the decorative frame 12 melts in the event of a fire, the iron plate 5 has a disaster prevention effect of preventing flames from entering or blowing out.

In particular, this design has a double structure consisting of an iron plate attached to the ventilation hole on the gable wall of the building and a wooden decorative frame attached to the outside of the iron plate. Even if the wood is destroyed in a fire, the iron plate inside will prevent the fire from entering or erupting, making it possible to create an exterior shape that takes advantage of the widely preferred wood material, and meeting demand while also taking fire resistance into account. This made it possible to meet the needs of people. Furthermore, slits are provided in both the decorative frame and the iron plate to create a double passage structure, and the slits in the decorative frame are sloped upward from the outside to the inside, so there is little risk of rainwater entering. In addition, since the decorative frame has multiple slits, it is possible to ensure sufficient ventilation even if the width of each slit is made small, which has the effect of preventing birds and rats from entering. Become. Moreover, a bent portion whose upper surface faces outward and descends in an inclined manner is provided continuously to the lower end portion of the iron plate, and the lower end portion of the decorative frame is disposed above the bent portion. Therefore, even if rainwater or the like enters between the outer decorative frame and the inner ventilation steel plate, it will be easily drained out along the upper surface of the above-mentioned bent part, preventing the accumulation of rainwater, etc. This has the advantage that corrosion of the steel plate caused by corrosion is prevented and durability is improved. In addition, the makeup frame is
If the roof shape is used as in this embodiment, the appearance of integration with the building can be emphasized compared to the conventional square shape, and the appearance will be better.
