Which are arranged side by side in parallel with each other, and the sound absorbing material 3 is attached to the inner surface of the mountain shape (Japanese Patent Laid-Open Publication No. Sho.
61-98890).
この従来のガラリでは防水効果が高く、通風性も良好で
あるが、防音効果を高めるにはガラリ全体の厚さａを大
きくする必要があり、また通風間隙４の片側の面は吸音
性がないため、構造上、高い遮音効果が望めないという
問題があった。This conventional gallery has a high waterproof effect and good ventilation, but in order to enhance the soundproofing effect, it is necessary to increase the total thickness a of the gallery, and one surface of the ventilation gap 4 has no sound absorbing property. Therefore, there is a problem that a high sound insulation effect cannot be expected due to the structure.
特に降雨時には、吸音材３の表面が濡れることにより遮
音性が低下するという問題があった。In particular, at the time of rainfall, there was a problem that the surface of the sound absorbing material 3 gets wet and the sound insulating property is deteriorated.
（発明が解決しようとする課題） 本発明は、上述の如き問題にかんがみ、防水効果が大き

たことにある。(Means for Achieving the Object) The features of the present invention for achieving the above-mentioned object are that an outer peripheral frame having a pair of horizontal horizontal rails vertically arranged and vertically fixed between the both horizontal rails. In a vertical soundproof and waterproof gallery that is provided with a large number of blades and serves as a ventilation gap between the blades,
The vane plate is provided with a mountain-shaped portion on the front side having a short slant portion and a long slant portion with different widths on the left and right, and a rear end edge of the long slant portion continuously arranged in the direction perpendicular to the thickness direction. Between the vane plates adjacent to each other, one of the short sloped portion and the other of the short sloped portion and the water return protrusion provided on the front surface of each open side edge of the rear surface plate portion. By arranging so that the rear surface plate portion of the back and front overlaps in the front-back and front-back direction, a large number of zigzag-shaped ventilation gaps leading to the front and rear are formed between them, and the back surface of the mountain portion and the front surface of the rear flat plate portion. The sound-absorbing material such as glass wool is fixedly installed in and.
（作用） 本発明の縦型防音防水ガラリにおいては、その前面側に

どの水滴が捕捉される。(Operation) In the vertical soundproof and waterproof gallery of the present invention, when wind and rain blows on the front side of the vertical soundproof and waterproof gallery, the depth between the mountain-shaped portions is gradually narrowed and the flow-in speed is increased to invade the edge of the short inclined portion. Approximately half of the water droplets are captured when riding over the water return protrusion of the section. Further, by bending zigzag at the front position of the rear plate part, most of the remaining water droplets are captured by the water return protrusions of the rear plate part.
一方背面側の騒音は、通風間隙の背面側開放部から侵入

面の吸音材に吸音され減衰される。On the other hand, the noise on the back side invades from the opening on the back side of the ventilation gap and collides with the sound absorbing material on the back side of the mountain portion, so most of it is absorbed and some of the reflected vibration is reflected on the front side of the back flat plate section. Sound is absorbed by the sound absorbing material and attenuated.

The side is the outdoor side and is installed in a ventilation port such as a ventilation port.When the wind and rain on the outdoor side blows, the front side of the ventilation gap 21 narrows the back side between the mountain-shaped portions 12, The air flow enters along the long slope while the flow velocity is accelerated, and the rear plate
The direction was changed in the front of 16 and the large water return projection piece 18
Most of the water droplets are caught by the projecting pieces 18 when the vehicle gets over the water and flow downward along the projections 18. Further, by colliding with the back surface of the mountain-shaped portion 12, the water droplets are removed again and blown out toward the indoor side from the back surface of the gallery.
また、屋内側の騒音は、ガラリの羽根板11の各部におい

面に当る音の振動がここで更に吸収される。Further, as for the noise on the indoor side, since the sound absorbing material is arranged on either of the front and back sides of each part of the blade plate 11 of the glass,
Vibrations are not easily released to the outside through the blades, and the vibrations of the sound that enter the ventilation gaps on the loose surface are absorbed by the sound absorbing material on the back surface of the mountain-shaped portion 12 and further reflected and hit the front surface of the rear surface plate portion. Vibrations of sound are further absorbed here.

ることとなったものである。(Effect of the Invention) As described above, in the vertical soundproof and waterproof gallery of the present invention, the sloping portion on one side of the mountain portion is lengthened, and the blade plates having the rear surface plate portion continuous to the edge portion are installed next to each other. By forming the zigzag ventilation gap, the indoor exposed portion and the outdoor exposed portion of the ventilation gap can be divided into a sound absorbing function and a waterproof function, and a thin overall and high sound absorbing and waterproof effect can be obtained. It has become.
また、羽根板は屋外側が山型になっているため、雨水が
侵入する屋外側の間隙開放部が広幅になり、その奥部が
狭められてジグザグ状になるため、屋外側の風とともに
侵入する水雨の除去がより完全となったものである。In addition, since the blade is mountain-shaped on the outdoor side, the gap opening on the outdoor side where rainwater enters is wide, and the inner part is narrowed to form a zigzag shape, so it enters with the wind on the outdoor side. The removal of water rain is more complete.
