BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ventilation building of a natural ventilation type which is constructed along a roof ridge in a long series.

[0002]

2. Description of the Related Art Generally, in a ventilation building of a natural ventilation type,
The internal space is divided into mazes to prevent wind and rain and wind and snow from blowing, and an example can be seen in Japanese Utility Model Publication No. 4-37145. In this type of ventilation building, as shown in FIG. 3, an outer wall 13 having an exhaust port 14 in the center of the upper surface, and a roof 1
Left and right inner walls 11.1 extending upward from the ventilation opening 3
1 and an inner upper wall 12 of a gabled roof which divides between the exhaust port 14 and the ventilation port 3 divides the internal space into a maze. Furthermore, there is a case where outer partition walls 9 are provided on the left and right inner surfaces of the outer wall 13 at regular intervals in the front and rear longitudinal directions (document unknown). The outer partition wall 9 is used to smoothly guide the air flowing from the central first compartment A to the left and right second compartments B and B to the third compartment C without moving in the longitudinal direction. belongs to.

[0003]

In such a ventilation building formed in a long series in front and rear, indoor air is taken into the first compartment A through the ventilation port 3 and the left and right sides of the first compartment A are taken from the first compartment A. The ventilation air is discharged to the outside through the second compartment BB and then the third compartment C. Therefore, there is an advantage that it can be constructed at low cost as compared with a configuration in which a large number of ventilators (ventilators) are individually provided on the roof. However, since the first compartment A is elongated along the ridge of the roof 1, the first compartment A
The amount of air flowing into the compartment A often varies in the longitudinal direction. For example, ventilation air may flow locally depending on the state of solar radiation and the location of the heater.

Under these circumstances, apart from the normal flow pattern from the first compartment A to the second compartment BB,
Ventilation air flows in the first compartment A along the front and rear longitudinal directions, and tends to cause an abnormal convection pattern, which impairs ventilation performance. Therefore, an object of the present invention is to prevent ventilation air from flowing in the front and rear longitudinal direction in the first compartment and improve the ventilation performance by smoothly guiding the ventilation air from the first compartment to the second compartment on the left and right sides. In order to get a natural ventilation type ventilation ridge.

[0005]

The ventilation building of the present invention is provided with a plurality of main frames 4 erected at regular intervals along ventilation holes 3 on the roof top, and provided on both sides of each main frame 4. Side frame 5.5
And An outer wall 13 having an exhaust port 14 at the center of the upper surface is provided outside the side frames 5. A pair of left and right inner walls 11, 11 extending above the ventilation opening 3 continuously from the upper surface of the roof 1 are fixed to both lower sides of the main frame 4.
A gable roof-shaped inner upper wall 12 inside the exhaust port 14 and along the upper wall of the outer wall 13 is fixed to the upper portion of the main frame 4.

[0006] A first compartment A at the center which is partitioned by the inner wall 11 and the inner upper wall 12 and communicates with the ventilation port 3;
11 and an outer wall 13, left and right second compartments BB that communicate with the first compartment A through an opening between the upper end of each inner wall 11 and the inner upper wall 12, and the inner upper wall 12 and Outer wall 13
And is divided into a third compartment C that communicates with the second compartment B. The left and right second compartments B, B are provided with outer partition walls 9 for dividing the compartments at regular intervals in the longitudinal direction of the front and rear. The first compartment A is provided with an inner partition wall 15 that partitions the upper portion of the first compartment A at regular intervals in the longitudinal direction.

[0007]

The inner walls 11 guide the air flowing into the first compartment A from the inside of the building through the ventilation opening 3 so as to rise in the first compartment A. At this time, the air colliding with the inner upper wall 12 tends to flow in the front and rear longitudinal directions along the inner surface of the inner upper wall 12. However, since the upper part of the inside of the first compartment A is partitioned at regular intervals in the longitudinal direction by the inner partition wall 15, the inflow air does not flow in the longitudinal direction along the inner upper wall 12, and is left and right as it is. Second compartment B ・ B
It is guided in a sort order. Subsequently, the air that has flowed into the second compartments B, B does not flow in the front and rear longitudinal directions on the outer partition wall 9, rises as it is, is guided to the third compartment C, and then flows out of the exhaust port 14. Go to

[0008]

Therefore, according to the ventilation building of the present invention, the air flowing into the first compartment A is guided to the left and right second compartments B, B without flowing in the front and rear longitudinal directions on the inner partition wall 15. Then, even in the second compartments B, B, the air does not flow in the front and rear longitudinal directions in the outer partition wall 9 and is guided to the third compartment C as it is. Natural ventilation can be performed reliably and efficiently.

The outer wall 13 has a plurality of outer wall members 13a of a horizontal type extending vertically outside the vertical frame portions 5b of the respective side frames 5, and the outer wall material 13a at the uppermost stage. And an outer wall material 13b covering the upper part. Of course, both ends in the longitudinal direction of the ventilation building are similarly covered with outer wall materials. Thus, the outer wall 13 having the exhaust port 14 is formed at the center of the upper end between the left and right outer wall members 13b. The exhaust port 14 is covered with an insect net 17 made of stainless steel. A small gap is formed between the left and right lower ends of the outer wall 13 and the roof 1, and the rain water that has fallen from the exhaust port 14 into the second compartment BB via the inner upper wall 12 in the gap is formed by the gap. It is discharged on 1.

In FIG. 3, the air inside the building is
Through the first compartment A, the second compartment B, and then the third compartment C to the outside through the exhaust port 14. In this ventilation process,
In order to prevent air from flowing in the front and rear longitudinal directions along the inner upper wall 12 in the first compartment A, the inner partition walls 15 are fixed to all the main frames 4. This inner partition 15
Is made of a pentagonal steel plate, and is attached so as to close the upper half of the main frame 4. The lower edge is the inner wall 11
Is located below the upper end of. The inner partition wall 15 and the outer partition wall 9 are represented by stippling in FIGS.

According to the ventilation building constructed as described above, the inner partition wall 15 partitions the upper part of the first compartment A at regular intervals in the longitudinal direction. Therefore,
When the room air that has risen into the first compartment A through the ventilation opening 3 is guided by the left and right inner side walls 11 and collides with the inner upper wall 12, the airflow flows along the inner upper wall 12. The inner partition wall 15 prevents flow in the front and rear longitudinal directions. That is, the inner partition wall 15 guides the air in the first compartment A to flow as it is to the second compartments BB on both the left and right sides.

Further, the outer partition wall 9 includes left and right second compartments B
B is partitioned at regular intervals in the front and rear longitudinal directions. Therefore, the air that has flowed into the second compartments B, B does not flow in the longitudinal direction, but is guided to the upper third compartment C as it is.

Each of the inner partition walls 15 may have a length reaching the lower end of the lower frame 4b of the main frame 4, or may extend to the indoor side further below the ventilation opening 3. Further, each of the inner partition walls 15 can be formed so that both left and right sides project into the second compartment B. The inner partition walls 15 need not be provided on all the main frames 4, but may be provided at regular intervals in the front-rear direction. Inner upper wall 1 instead of main frame 4
The inner partition wall 15 may be fixed to the second partition 2 or the like.
