Description

BACKGROUND OF THE INVENTION Field of the Invention [0001] The present invention relates to a soundproof wall capable of eliminating wind pressure and noise absorption,

More particularly, the present invention relates to a soundproof wall, and more particularly, to a soundproof wall capable of rapidly absorbing and absorbing noise through a front surface of a soundproof wall when a noise is introduced through a vehicle or the like, Which is capable of eliminating wind pressure and absorbing noise quickly.

Generally, the soundproof wall is installed at a predetermined height from the ground along the longitudinal direction at both side edges of the railway and the roadside adjacent to people's living space, and prevents the noise source generated by the running of the vehicle from being transmitted to the living space.

The soundproof wall is variously classified into a metal soundproof wall, a concrete soundproof wall, a transparent soundproof wall, and a wooden soundproof wall according to the characteristics of the soundproof plate that blocks or absorbs noise.

The metal soundproof wall has a plurality of slit holes arranged vertically so that noise can be introduced into the front surface thereof, and a sound absorbing material for noise absorption is provided inside the metal soundproof wall, so that the noise of the vehicle passes through the slit hole and is absorbed through the sound absorbing material.

In the above case, since a plurality of slit holes are narrowly formed on the front surface of the sound insulating plate, noise is more reflected than the inflow amount when the noise is introduced, which makes it difficult to eliminate noise.

Transparent soundproofing walls are wrapped around a panel of transparent material in a frame and then vertically arranged vertically between the strut and the strut through the frame. They are installed mainly for the purpose of securing the view or sunshine, and have recently been applied in combination with other soundproofing panels.

In the above case, although the appearance is good, it is advantageous in securing the view right, but the noise is struck by the transparent panel and is reflected as it is, thereby causing noise pollution when the noise is large.

The wooden sound barrier is composed of wood panels arranged in various shapes on the front and rear surfaces of the soundproof plate arranged vertically between the support and the support, and the surroundings are aesthetically pleasing due to the characteristics of environment friendly materials.

In the above case, the appearance may be beautiful, but the noise is reflected as it is, so that it is difficult to block the noise source.

On the other hand, in the recent soundproofing boards, a mixed soundproofing wall which simultaneously secures the viewpoint, eco-friendly material, and noise absorbing function has been proposed, and also various forms have been produced.

As an example, Korean Patent Publication No. 10-2010-0074451 entitled "Ventilation type soundproof wall"

The soundproof panel includes a plurality of soundproofing plates and a support for supporting both ends of the soundproofing plate. Both ends of the soundproofing plate are pivotally connected to the support by a fixing pin. When the soundproofing plate is winded at a predetermined wind speed or more The sound insulating plate is turned and opened.

Accordingly, by opening the entire soundproofing plate when a strong wind blows, the wind load received by the soundproof wall can be reliably reduced and stability can be secured.

That is, since the soundproof plate is opened only when the wind exceeds the wind speed, the soundproof wall acts as a soundproof wall when the normal wind is blown, and wind can pass through the soundproof walls only when the wind is strong as in the typhoon .

However, in the case of the above-mentioned soundproof plate, it is possible to solve the wind pressure, but it has a drawback in that it can not absorb vehicle noise.

In addition, a plurality of soundproof walls for relieving wind pressure have been proposed in Korean Patent No. 10-0561088 and Japanese Patent No. 10-0935155.

However, even in the case of the soundproof wall described above, the wind pressure can be solved to some extent, but the noise generated with the wind pressure can not be solved, and the noise is transmitted as it is.

In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may obscure the subject matter of the present invention. do.

The present invention relates to a soundproofing plate 200 arranged vertically between a strut 100 and a strut 100a arranged equidistantly on the edges of a road as shown in Figs. 1 to 4 to absorb wind pressure and noise .

1 and 2, the sound-absorbing panel 220 includes a sound-absorbing material 220 that absorbs and dissipates the introduced noise, and a pair of upper and lower and right and left sound-absorbing materials 220 that surround the edge of the sound- A rear plate 260 which forms a rear surface of the sound absorbing material 220 and has a rim end fixed to the rim 240 and a rear plate 260 which is a front surface of the sound absorbing material 220, And a plurality of slit plates 280 which are fixed by the slit plate 280.

The sound absorbing material 220 may be the same sound absorbing material as that of the sound absorbing material applied to the known art. The sound absorbing material 220 may be formed by twisting a sponge or a metal sheet so that the noise is absorbed and then extinguished.

The frame member 240 is formed to have a rectangular shape in which the ends of the upper and lower frame members 241 and 242 and the left and right frame members 243 and 244 are connected to form a rectangular shape, do.

The slit plates 280 are arranged in a longitudinal direction with respect to the front surface of the sound absorbing material 220 so that a plurality of left and right slit plates 280 are arranged and the upper and lower ends of the slit plates 280 are respectively connected to upper and lower frame members 241 242, and an inclination angle 282 is formed in one of the left and right directions to form the opening 300 so that noise and wind flow in.

Here, it is preferable that the opening 300 constituting the slit plate 280 is arranged to be opened in a direction in which noises and wind pressure are introduced into the vehicle while the vehicle is traveling on the road.

In addition, the slit plate 280 and the slit plates may be arranged at different intervals in the turning section of the road.

The slit plate 280 is formed by bending an adhering surface 284 so that one end of the slit plate 280 is in close contact with the surface of the sound absorbing agent 220 and the upper and lower ends of the other end are bent 240 are formed to be in close contact with and fixed to the inner wall of the contact surface 284.

In addition, in the case of the opening 286, it is possible to form a corrugated bend 290 so that noise and wind can be reflected by the surface where the bump occurs when noise and wind are introduced. 5)

The protrusion 400 is formed on the upper frame member 241 and the groove 410 is formed on the lower frame member 242 so that the protrusion 400 and the groove 410 are formed when the sound insulation plate 200 is vertically arranged. And the upper and lower gaps of the soundproof plate and the soundproof plate are cut off when noise is generated on the front surface.

The rear plate 260 is tightly coupled to the back surface of the sound absorbing material 220 and forms a space 500 between the back plate 260 and the sound absorbing material when the sound absorbing material is coupled. It is possible to cause the diffraction phenomenon to occur in the space portion 500.

Hereinafter, the installation and application of a sound barrier capable of eliminating wind pressure and sound absorption according to the present invention will be described in detail with reference to the accompanying drawings.

When assembling the soundproof plate,
