Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ventilation structure for an outer wall which is used to provide the outer wall with a ventilation function.

[0002]

2. Description of the Related Art In recent years, various types of materials have been provided in which an exterior material is attached to the outer surface side of an outer wall body via a ventilation gap, and the outer wall is ventilated by ventilating the ventilation gap. When air is ventilated through this ventilation gap, outside air is taken into the ventilation gap at the base portion, and the air that has passed through the ventilation gap is exhausted from the partition near the roof.

[0003]

However, in the case of a building with a high height such as a two-story building or a three-story building, the length of the ventilation gap in the up-down direction becomes long, and the resistance when ventilating is large. There was a problem that smooth ventilation was not possible. The present invention has been made in view of the above problems, and an object of the present invention is to provide a ventilation structure of an outer wall capable of exhausting air smoothly between floors even in a tall building. ..

[0004]

In order to achieve the above-mentioned object, the ventilation structure of the outer wall of the present invention has a ventilation curtain plate in which an exterior material 3 is attached to the outer surface side of an outer wall body 1 through a ventilation gap 2 and the inside is hollow. 4 is arranged between the exterior material 3 on the upper floor and the exterior material 3 on the lower floor, and the ventilation curtain plate 4 is attached to the barrel 5 of the outer wall body 1, and the ventilation gap 2 and the ventilation curtain on the lower floor are attached. It is characterized in that the ventilation curtain plate 4 is provided with a ventilation port 6 which communicates with the inside of the plate 4 and communicates with the outside.

[0005]

[Function] Even between floors such as the first floor and the second floor, the ventilation gap 2 can be exhausted by the ventilation curtain 4 and the length of the ventilation gap 2 between the portion sucked into the ventilation gap 2 and the portion discharged from the ventilation gap 2. The length is shortened to reduce the resistance of ventilation, allowing smooth ventilation.

EXAMPLE First, the example of FIG. 1 will be described. The outer wall body 1 is formed by loading a heat insulating material between columns, and a barrel insert 5 is provided on the outer wall body 1 between the first floor and the second floor. The exterior material 3 is made of ceramic material, has a frame 7 attached to the back surface thereof, and has locking recesses 8 at the upper and lower ends of the frame 7. The exterior material 3 is arranged on the outer surface side of the outer wall body 1 with a ventilation gap 2 in between and attached to the outer wall body 1. The ventilation curtain plate 4 is formed in a box shape that is long in the width direction with the rear surface opened, and mounting plates 9 are provided above and below the back. The ventilation curtain plate 4 is arranged on the outer surface side of the body insert 5, and is attached to the mounting plate 9
It is attached by attaching to the barrel 5. Locking projections 10 are projected from the upper surface and the lower surface of the ventilation curtain plate 4, and the exterior material 3 is supported by locking the locking projections 10 in the locking recesses 8. A ventilation port 6 is provided on the lower surface side of the ventilation curtain plate 4 for communicating the inside of the ventilation curtain plate 4 with the outside, and the inside of the ventilation curtain plate 4 and the ventilation gap are provided on the upper and lower surfaces of the ventilation curtain plate 4. A communication hole 11 for communicating with 2 is provided. Then, the air rising in the ventilation gap 2 below the ventilation curtain 4 flows into the ventilation curtain 4 through the communication hole 11 and is exhausted to the outside from the ventilation port 6 through the ventilation curtain 4. Part of the air from inside the ventilation curtain plate 4 flows into the upper ventilation gap 2 through the communication hole 11.

FIGS. 2 and 3 show the structure of a portion of the base portion that sucks air into the ventilation gap 2. A base metal fitting 13 having a U-shaped cross section is arranged on the outer surface side of the base 12 of the outer wall body 1, and a back surface portion 13a of the base metal fitting 13 is fixed to the base 12 by a fastener 14 such as a screw. The front surface portion 13b of the metal fitting 13 is locked in the locking concave portion 8 of the frame 7 of the exterior material 3, and the intake hole 15 is formed in the bottom surface portion 13c of the base metal fitting 13.
Is perforated. Then, the outside air is sucked into the ventilation gap 2 through the intake hole 15, and the air rises in the ventilation gap 2. Further, FIG. 4 shows an intermediate rail 16 used in a portion connecting the vertically adjacent exterior materials 3, which is formed in a substantially H-shaped cross section. The back surface portion 16a of the intermediate rail 16 is attached to the outer wall body 1
And the upper and lower sides of the front surface portion 16b are locked in the upper and lower locking recesses 8 of the frame 7 of the exterior material 3, respectively.
A communication hole 17 is drilled in c to allow vertical ventilation.

FIG. 5 shows another embodiment. In the case of this embodiment, the vertical furring strip 18 is attached to the outer surface side of the outer wall body 1, and the exterior material 3 is attached to the outer surface side of the vertical furring strip 18 to form the ventilation gap 2 between the exterior material 3 and the outer wall body 1. Has been formed.
Also in this case, the ventilation curtain plate 4 is attached to the outer surface side of the barrel insert 5 of the outer wall body 1, and the air flowing into the ventilation curtain plate 4 from the lower ventilation gap 2 through the communication hole 11 is used as the ventilation port 6. Exhausted from the outside. In addition, a ventilation curtain 4 is provided in the upper ventilation gap 2.
Is sucked in from above.

[0009]

As described above, according to the present invention, the ventilation curtain plate having a hollow inside is arranged between the exterior material of the upper floor and the exterior material of the lower floor, and the ventilation curtain plate is used as a glove of the outer wall body. Since it is attached and the ventilation gap on the lower floor communicates with the inside of the ventilation curtain, the ventilation curtain also has a ventilation port that communicates with the outside, so it is between the first floor and the second floor. It is something that can be exhausted to the outside from the mounted ventilation curtain, the vertical length between the part that sucks air into the ventilation gap and the part that exhausts air can be shortened,
Even in a two-story or a three-story building, the ventilation resistance can be reduced to allow smooth ventilation, and the ventilation curtains can be used to accentuate the outer surface of the outer wall to achieve a design effect. Is.
