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 waterproof gallery for ventilation, the shape and arrangement of the louver body under the worst conditions in consideration of the amount of rainfall per hour and the blowing wind speed in ventilating the indoor air while preventing rainwater from entering the room. The interval is set, for example, as the main body of a horizontal waterproof louver,
Some are shown in the figure.

The louver body 18 has a narrow vertical width which is approximately the same as the vertical width of the vertical plate portion 19 for reinforcement located at the end on the outdoor side and the vertical plate portion 19 continuously provided from the upper end to the indoor side. Slope plate
20, a steep inclined plate portion 21 continuously provided from the inclined upper end toward the indoor side to the vicinity of the center in the width direction, a gently inclined plate portion 22 continuously provided from the inclined upper end to the indoor side, and from the inclined upper end It is composed of a rising plate part 23 that rises vertically and has a water repelling part formed on the upper end so that water droplets scattered from the lower end of the vertical plate part 19 fall onto the steeply inclined plate part 21 of the lower gallery body 18. It had been.

However, in the above-mentioned conventional example, rainwater may enter the room during strong winds, and in terms of performance as a waterproof gallery,
There was a problem.

Then, the present inventors came to grasp the following facts as a result of repeating many experiments to elucidate the cause of rainwater invasion.

That is, in the above conventional example, the cross-sectional shape of the louver body 18 is
Generally, it has a bent shape that is convex upward in the widthwise central portion,
The interval between the lower end of the vertical plate portion 19 of the upper gallery body 18 and the upward convex bent portion of the lower gallery body 18 was relatively small.

Therefore, even with a slight wind, the water droplets scattered from the lower end of the vertical plate portion 19 are steeply inclined plate portions in the lower gallery body 18.
It will exceed 21 and will fall on the gently inclined plate part 22,
The advantage of providing the steeply inclined plate portion 21 is not utilized.

Moreover, in the ventilation path between the upper and lower louver bodies 18, 18,
When the wind speeds on the upstream side of the ventilation path, the middle part of the ventilation path, and the downstream side of the ventilation path were measured, the wind speed was faster on the upstream side, and therefore,
The above phenomenon is accelerated. That is, since the wind speed is higher on the upstream side, most of the rainwater that has entered the upstream side of the ventilation passage moves to the downstream side of the ventilation passage while riding on the force of the wind without contacting the louver body 18, and efficiently A large amount of rainwater comes into contact with the louver body 18 and is captured on the downstream side of the ventilation passage, and the rainwater not captured here enters the room.

[Problems to be solved by the device]

The present invention was made based on the above experimental results, and its purpose is to effectively prevent rainwater from entering the room by devising the cross-sectional shape and interval of the louver body. It is to provide a waterproof gallery that can be done.

[Means for Solving the Problems]

A feature of the present invention is a waterproof gallery in which a plurality of lateral louver bodies are vertically spaced from each other in a gallery frame body, and each louver body is located at an end on the outdoor side. A vertical plate portion, a first swash plate portion that is wider than the vertical width of the vertical plate portion that is continuously provided from the upper end of the vertical plate portion in the depth direction, and is inclined so as to be higher toward the indoor side, and the inclination thereof. A second swash plate portion that is steeper than the first swash plate portion that is continuously provided from the upper end to the indoor side, and a gentler slope than the second swash plate portion that is continuously provided from the upper end to the indoor side. A third swash plate part in which an inclined lower end is made to project slightly to the outdoor side from the inclined upper end of the second swash plate part to form an intermediate water return part, and a third swash plate part that rises vertically from the inclined upper end and returns to the upper end It is composed of the rising plate part where the part is formed, and the vertical Third diagonal spacing between the first swash plate portion at the lower end and the lower louver body parts l _1, in the bending portion and the lower louver body of the first swash plate and the second swash plate in the upper louver body If the distance between the inclined lower end of the plate part is l ₂ and the distance between the lower end of the rising plate part in the upper gallery body and the upper end of the rising plate part in the lower gallery body is l ₃ , then l ₁ > l ₂ > l _It is configured to be ₃ .

[Action]

According to the above configuration, the first swash plate portion, which is wider in the depth direction than the vertical width of the vertical plate portion, and the upper end of the slope are connected to the inside from the middle of the louver body in the depth direction. Since it has a cross-sectional shape that is recessed downward due to the steeply inclined second swash plate portion, the rainwater that has scattered from the lower end of the vertical plate portion falls between the steeply inclined second swash plate portion and the steeply inclined second swash plate portion. It's easy to do.

Further, since the inclined lower end of the third swash plate portion is protruded from the inclined upper end of the second swash plate portion to form the intermediate water return portion,
There is no risk of rainwater falling on the swash plate portion moving to the third swash plate portion due to wind.

Moreover, the distance between the lower end of the vertical plate portion of the upper gallery body and the first swash plate portion of the lower gallery body is l ₁ , and the bent portion of the first swash plate portion and the second swash plate portion of the upper gallery body is 1. l ₂ the distance between the inclined lower end of the third swash plate in the lower louver body, the distance between the upper end of the rising plate portions at the lower end and the lower louver body of the rising plate part in the upper louver body was l ₃ and At this time, since the configuration is such that l ₁ > l ₂ > l ₃ , the wind speed becomes slower on the upstream side of the ventilation passage, and the catchment of rainwater by the louver body on the upstream side of the ventilation passage is efficiently performed. The amount of water moving to the downstream side will decrease.

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,
It is discharged to the lower side of the waterproof gallery, and the amount of rainwater flowing down from the upper part of the waterproof gallery is drastically reduced.

Then, for each of the rainwater that directly blows into the ventilation passage R between the louver bodies 6 and 6 and the rainwater that flows down from the reinforcing plate portion 14, the speed when passing through the ventilation passage upstream side is slow. Therefore, the rainwater can be effectively contacted with the ventilation surface and collected, and further rainwater can be collected and collected on the downstream side of the ventilation passage to effectively prevent the rainwater from entering the indoor side. it can.

In addition, since the second swash plate portion 15 has a steep slope and the intermediate water return portion A is formed on the upper side of the second swash plate portion 15, rainwater is prevented even under strong wind and rain. Third swash plate
Good discharge to the outside without moving to 16 side.

Alternatively, with respect to rainwater contacting the third swash plate portion 16 as well, since the rising dimension of the vertically rising plate portion 18 is large and the water return portion B is formed on the upper edge side thereof, Rainwater will not enter the room beyond the rising plate 17.
