Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to an attic structure, with particular emphasis on the ventilation function.

(Prior art) In order to improve ventilation in the attic, when fishing on a boat, measures are taken such as providing ventilation holes in the eaves.
(Refer to Publication No.-30324).

However, in recent years, buildings without eaves have been seen, especially in reinforced concrete (RC) buildings, which are built up to the height of the outer walls or roof.

In such buildings without eaves, it is not possible to open ventilation holes in the soffits, so conventionally, ventilation holes are opened in the outer wall at the location leading to the attic, and the attic is ventilated through the ventilation holes. Trying to ventilate (Jikko 55)
(See Publication i0816).

(Problems to be Solved by the Invention) However, in such a conventional attic structure, it is difficult to obtain a sufficient ventilation function unless a plurality of ventilation holes are provided at predetermined intervals. However, since these ventilation holes are exposed on the surface of the outer wall, they impair the aesthetic appearance of the building.

Another problem is that rainwater running down the outer surface of the exterior wall can easily seep into the attic through the ventilation holes, so it is necessary to devise measures to prevent rain from entering each ventilation hole, which requires construction work. was there.

Therefore, the present invention focuses on the above-mentioned conventional problems, and provides an attic structure that can sufficiently ventilate the attic without impairing the beauty of the building, and prevents rainwater from penetrating into the attic from the ventilation passage. It is intended to.

(Means for Solving the Problems) The present invention has been made for the purpose of solving the above-mentioned problems, and in order to achieve this purpose, the attic structure of the present invention has a structure in which the upper end of the outer wall is In an attic structure that extends to a height of The upper part of the gap is covered with a waterproof board and is opened to the attic below, and above the upper end of the outer wall, an air flow path is formed by a cover material to extend around the entire width of the outer wall. The air passage has one end open to the gap and the other end facing downward and open to the outside.

(Function) In the attic structure of the present invention, between the upper end of the outer wall and the roof,
A gap is formed that spans almost the entire width of the outer wall, the upper part of the gap is covered with a waterproof board, the lower part is opened to the attic, and above the upper end of the outer wall, a cover material is used to cover the outer wall. An air passage spanning almost the entire width is formed, and one end of the air passage is opened into the gap, and the other end is directed downward and opened to the outside, so that the air passage is formed by the upper end of the outer wall, the roof, and the ceiling. The attic is connected to the outside through the gap and the air passage. Therefore,
The attic is ventilated to the outside through a wide area that spans almost the entire width of the outer wall, so there is sufficient ventilation.

Further, since the air passage is opened downward at the front side of the upper end of the outer wall, rainwater that has flowed through the cover material is difficult to enter into the air passage.

(Example) Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

First, the configuration of the embodiment will be explained based on FIG.

FIG. 1 is a vertical cross-sectional view showing the attic structure of this embodiment. In the figure, 1 is an exterior wall panel that makes up the exterior wall, 2 is a panel that makes up the roof, and 3 is a ceiling panel that makes up the ceiling. The uppermost outer wall panel 1 constituting the section is provided at the height of the roof panel 2.

Further, the roof panel 2 is provided substantially horizontally so as to be parallel to the ceiling panel 3, although it has a slight water slope. Further, the outer wall panel 1 and the roof panel 2 are A

The ceiling panel 3 is made of a hard wood cement board or the like.

Further, 4 indicates an attic, and this attic 4 is surrounded by the upper end of the outer wall, the roof, and the ceiling.

Furthermore, a cross-sectional frame 5 is fixed to the back surface of the outer wall panel 1, and the frame 5 is fixed to a girder 6 with a regent 7. Further, the roof panel 2 is also fixed to the girder 6, and a waterproof sheet 8 made of a soft vinyl chloride resin sheet or the like covers almost the entire upper surface of the roof panel 2.
is installed. Incidentally, a gap a is provided between adjacent roof panels 2.2, and the upper surface of this gap a is closed with the waterproof sheet 8, and the lower surface of the gap a is open to the attic 4. Further, the ceiling panel 3 is fixed to a small beam 10 via a roof edge 9.

Furthermore, non-combustible facing materials 11 and 12 such as calcium silicate plates are provided at the peripheral edge of the girder 6 on the lower surface and inside of the girder 6, and the non-combustible facing material 11 and the outer wall panel 1 A noncombustible filler 13, 14 such as glass fiber is provided between the noncombustible panel 12 and the roof panel 2, respectively.

The main configuration of the attic structure in an ALC building has been described above, but in this embodiment, in order to ventilate the attic 4, the attic structure is further configured as follows.

First, a gap is formed between the outer wall panel 1 and the roof panel 2, which constitute the upper end of the outer wall, and spans almost the entire length of the outer wall. The upper part of this gap is covered with a waterproof plate 15, and the lower part thereof is opened to the attic 4. The waterproof board 15 is provided across the outer wall panel 1 and the roof panel 2, and the edge on the roof side is glued to the top surface of the roof panel 2, and the edge of one example of the outer wall panel is attached to the girder 6. It is glued to a fixed bracket 1γ.

Further, above the outer wall panel 1, an air passage C extending around almost the entire width of the outer wall is formed by a cover material 16, and one end of this air passage C is opened into the gap, and the other end is opened into the gap. It faces downward and is open to the outside. A plurality of the cover members 16 are connected in the longitudinal direction by joiners 18 and are provided to cover the upper end portion of the outer wall panel 1. The joiner 18 is screwed to the bracket 1γ, and the cover material 16
is fitted to the joiner 18. The brackets 17 are provided along the girder 6 at predetermined intervals.

Further, reference numeral I9 denotes a water return plate, which is fixed to the upper end of the outer wall panel 1, stands upright so as not to block the air passage C, and has its upper end folded back outward.

Next, the operation of the embodiment will be explained.

In the attic structure of this embodiment, the attic 4 formed by the upper end of the outer wall, the roof, and the ceiling is located above the outer wall panel 1 through the gap formed between the outer wall panel I and the roof panel 2. It communicates with the outside via an air passage C formed in the. Since the air passage C is provided over the entire length of the outer wall, the attic 4 is ventilated with the outside in a wide area that spans almost the entire length of the outer wall. In this embodiment, in order to ensure fire resistance, the attic 4 or the inside part of the girder 6 is partitioned by a noncombustible panel 12, or the inside and outside of the noncombustible panel 12 are connected to the adjacent roof panel 2. , 2 and the gap between the outer wall panel 1 and the roof panel 2, sufficient ventilation is provided throughout the attic 4. In addition, some ventilation is performed inside and outside the noncombustible panel 12 through the noncombustible filler 14 provided between the noncombustible panel 12 and the roof panel 2.

Further, since the air passage C is opened downward and to the outside, rainwater that has flowed down the cover material 16 flows directly along the surface of the outer wall panel 1 and becomes a swamp. That is, it is difficult for rainwater to enter through the air passage C.

Furthermore, even if rainwater enters the air passage C by being blown up by the wind, there is a water return plate 19 inside the air passage C.
is provided, so that rainwater is guided out of the outer wall panel 1 again by this water return handler 19.

In this way, with the attic structure of this embodiment, there is no need to make holes in the outer wall panel 1, so the beauty of the animal is not spoiled, and the attic 4 can be sufficiently ventilated. In addition, it has the effect of making it difficult for rainwater to enter the attic 4 from the gaps and ventilation passages such as the air passage C.

Although the embodiments of the present invention have been described above in detail with reference to the drawings, the specific configuration is not limited to these embodiments, and even if there are design changes within the scope of the gist of the present invention, they are included in the present invention. It will be done.

For example, in the example, it was applied to an ALC building, but
It may also be applied to RC buildings.

(Effects of the Invention) As explained above, the attic structure of the present invention allows sufficient ventilation of the attic without spoiling the beauty of the building, and prevents rainwater from entering the attic from the ventilation passage. The effect is difficult to obtain.
