Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a waterproof gallery for ventilation provided on a wall portion of an air-conditioning room, an electric room, an elevator room or the like.

[Conventional technology]

For the above-mentioned waterproof gallery for ventilation, the shape and arrangement of the louver body under the worst conditions in consideration of the rainfall per hour, the blowing wind speed, etc. in ventilating the indoor air while preventing the entry of rainwater into the room. The interval is set.

[Problems to be solved by the invention]

Here, looking at the amount of rainwater that is one of the criteria for setting the above interval, the amount of rainwater that flows into the waterproof gallery along the outer wall surface above the waterproof gallery as well as the amount of rainwater that blows into the waterproof gallery itself. In particular, there was a tendency for rainwater to easily enter the room through the ventilation part between the main bodies of the water vapor, especially on the upper side of the water vaporizer.

[Means for solving problems]

The present invention has been made in view of the above situation,
The purpose thereof is to effectively prevent the intrusion of rainwater from the upper part of the waterproof louver due to the rainwater falling along the outer wall surface.

The technical means taken by the present invention to achieve the above object are as follows. That is, a feature of the present invention is that, in a waterproof gallery in which a plurality of lateral louver bodies are vertically spaced from each other in a gallery frame body, an upper horizontal frame of the gallery frame body and an uppermost gallery body are provided. In between, and the rainwater flowing down from the upper horizontal frame is provided over the left and right vertical frames of the louver frame body, and the rainwater received by the receiving gutter along the vertical frame is It is characterized in that a water guiding portion that flows down to the upper surface of the lower horizontal frame is provided in communication with the receiving gutter.

[Action]

According to the above characteristic structure, most of the rainwater flowing down along the outer wall surface of the upper part of the waterproof louver is received by the catch gutter before reaching the ventilation part between the louver bodies, and the received rainwater flows down the water guiding part. Then, it is discharged from the lower horizontal frame to the outer wall surface portion on the lower side of the waterproof gallery.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows the entire waterproof gallery, and FIGS. 2 to 5 show the essential parts thereof.

In such a waterproof gallery, upper and lower horizontal frames 3 and 4 are joined to a pair of left and right vertical frames 2 and 2 in which a vertical water guiding portion 1 is formed to form a gallery frame body 5 and the louver frame body 5 Left and right vertical frames
A plurality of louver bodies 6 ... Are provided at a predetermined interval above and below 2, 2 and an upper horizontal frame 3 of the louver frame body 5 is provided.
A rainwater catchment gutter 7 flowing down from the upper horizontal frame 3 and the uppermost louver main body 6 and over the left and right vertical frames 2, 2 are provided. For example, a building outdoor wall 8 for ventilation of an electric room or the like. It is installed in the opening 9 of the.

The left and right vertical frames 2,2 and the upper and lower horizontal frames 3,4, and the louver body 6 and the receiving gutter 7 are each made of an extruded product of an aluminum material. And upper and lower horizontal frames
A plate portion 11 for forming a gap for burying the water blocking material 10 between the opening 9 and each of the openings 3 and 4 is continuously provided.

Then, on the louver body mounting surface portions of the left and right vertical frames 2 and 2, in the widthwise intermediate portion of the louver body 6 outside the screw fixing portions a, a vertical water guiding portion 1 formed of a groove is formed. The receiving gutter 7 is formed in a state of communicating with the water conduit 1.
Is installed.

On the other hand, at the lower corner portion of the outdoor side surface portion of the upper horizontal frame 3, a draining plate portion 12 whose lower end edge faces the upper portion of the receiving gutter 7 is continuously provided, and the upper outdoor frame 8 is passed from the building outdoor wall 8. The rainwater flowing down is guided to the receiving gutter side, and the rainwater is poured into the receiving gutter 7.

According to the above configuration, under rain, the rainwater that flows down from the upper horizontal frame 3 along the outer wall surface of the upper portion of the waterproof gully is guided by the draining plate portion 12 and flows into the receiving trough 7, and from both sides of the receiving trough 7. Through the water conduit 1 to the upper surface of the lower horizontal frame 4,
From there, it is discharged to the bottom of the waterproof gallery.

Thus, by drastically reducing the amount of rainwater flowing down from the upper part of the waterproof gallery, the invasion of rainwater into the room through the ventilation part between the gallery bodies 6 is effectively suppressed.

Although it is preferable to provide the water guiding portion 1 on both the left and right vertical frames 2 and 2 in terms of drainage, the water guiding portion 1 may be provided on only one of the left and right vertical frames 2 and 2.

Further, when the receiving gutter 7 is provided on the upper horizontal frame 3 so as to project slightly outward from the outdoor side surface portion, the draining plate portion 12 can be omitted.

In addition, the louver body 6 is separated by a predetermined distance from the upper and lower horizontal frames 3,
The present invention can be applied to a waterproof louver that is provided over four areas.

[Effect of device]

As described above, the waterproof gallery of the present invention receives rainwater flowing down the outdoor wall of the building and flowing down to the upper side of the waterproof gallery by the catch gutter until the rainwater reaches the ventilation section between the gallery bodies. It is designed to be discharged to the lower side of the waterproof gallery through the water guide part along the vertical frame, and by structurally simple improvement, most of the rainwater flowing down the upper horizontal frame and reaching the ventilation part between the louver bodies is almost By eliminating it, it has become possible to effectively prevent rainwater from entering the room on the upper side of the waterproof galleries.
