Soundproof walls having sound insulation and absorbing the sound structure

The present invention relates to a soundproof wall for absorbing / blocking road noise, and more particularly, to a soundproof wall having a light weight, which is easy to manage according to installation and maintenance, and has an excellent soundproofing and soundproof structure. will be.

In general, a soundproof wall is installed around a roadside or a railway where noise of the vehicle is generated to absorb or block the noise of the vehicle. Such sound barriers are intended to be installed in the longitudinal direction of the road so that noise is not transmitted to adjacent buildings or houses.

The conventional soundproof wall is composed of a reinforcing member fixed to the ground along the longitudinal direction of the road, a support standing on the upper surface of the reinforcing member and installed at equal intervals, and a soundproof block arranged up and down between the supporters. In addition, such soundproof blocks are formed to form a soundproof wall while a plurality of layers are stacked vertically or connected left and right.

In addition, the soundproof block constituting the conventional soundproof wall is provided in a relatively diverse shape and shape, but most of the metal is filled with a predetermined sound absorbing material inside the housing, the sound absorbing holes are formed at regular intervals on the front surface have.

In the conventional soundproof walls composed of metal soundproof blocks, since the front and rear surfaces are mostly flat, there is a sound insulation effect that reflects noise generated on the road, but the sound absorption effect is insignificant. Therefore, there is a problem that it is difficult to effectively block the noise generated in the road or the railroad to expect the sound absorbing effect as desired.

In particular, in the case of the metal sound insulation block is vulnerable to snow or rain water, there is a disadvantage that easily corroded, when the corrosion soundproof wall is left as it is, there is a problem that inhibits the aesthetics of the road. In addition, there was a problem that increases the economic burden of the reconstruction.

Therefore, in recent years, a soundproof wall made of concrete has been disclosed to solve some of the above problems. The concrete soundproof wall is provided with a ventilation hole on the front surface, a predetermined space portion is provided in communication with the ventilation hole therein, the sound absorbing material such as glass fiber is provided in close contact with the space portion.

The concrete soundproof wall as described above is to be constructed so as to be stacked vertically or connected continuously to the left and right, while the noise is introduced into the interior through the air vents in the front at the same time the sound absorbing material to absorb the noise and disappear.

However, such a conventional concrete soundproof wall is installed in a state in which the sound-absorbing material for absorbing / removing the noise is in close contact with the inside of the space portion, it is difficult to expect the desired sound-absorbing effect because the noise does not flow well through the interior.

In addition, since the conventional soundproof wall formed of concrete is provided as a single body, when the damage caused by the collision of the vehicle, etc., the entire soundproof wall must be replaced even if only a part of the soundproof wall is broken, so that the economical loss and management cost of the reconstruction are high. There was a problem.

Moreover, the conventional soundproof walls have a disadvantage in that the installation work is not easy because most of them will be manufactured by weight due to the characteristics of the material.

On the other hand, such a sound barrier is mainly installed on the side of the road, when the collision of the vehicle there is a concern that the vehicle is largely damaged by a soundproof wall formed of solid concrete, or cause large accidents such as human injury.

In addition, the existing concrete soundproof walls installed along the roadside are not only deficient in appearance by focusing on the functional elements to increase the soundproofing effect, but also have a very rough and cold feeling because the rear surface is simply formed of concrete walls. There was a disadvantage.

The present invention has been made to solve all the problems of the prior art as described above,

An object of the present invention is to provide a soundproof wall that can be reduced in weight to facilitate installation and maintenance work according to construction.

Second, in order to allow partial replacement work in case of damage, it is easy to manage according to maintenance.

Third, it is to provide a new type of sound barrier with excellent sound absorbing effect as well as sound insulation effect on noise.

Fourth, by adding a decorative element to the rear of the soundproof wall, it is possible to maintain the beauty of the road beautifully.

The present invention for achieving the above object is in the soundproof wall for absorbing or blocking the noise of the vehicle is installed on the road, bridge, etc.,

A soundproof block is formed on the front surface, and the soundproof block in which the hollow sound absorption part was formed inside;

A sound absorbing hole communicating with the sound absorbing portion and formed in front of the sound absorbing portion;

A sound absorbing member mounted inside the sound absorbing unit and absorbing / removing noise introduced into the inside of the sound absorbing hole; And

It can be achieved by a soundproof wall having a sound insulation and sound-absorbing structure made of a soundproof block and a fixed block detachably installed.

As described above, according to the soundproof wall having sound insulation and sound absorption structure according to the present invention,

First, since it is possible to manufacture a lightweight soundproof wall by mixing the slab (泥 板岩) and the resin material, it is easy to install and repair according to the construction of the soundproof wall, it is possible to obtain the effect of ensuring stability when a collision occurs.

Second, since the soundproof block and the fixed block are assembled in a detachable state, a partial replacement is possible, so that the replacement work is easy when the soundproof wall is damaged, thereby reducing the replacement cost as much as possible.

Third, since the externally generated noise is primarily scattered / removed from the sound insulation unit, and the sound absorbing member is completely absorbed and removed by the sound absorbing member, the sound insulation and sound absorption effect is remarkably increased.

Fourth, since it is possible to implement various forms of decorative beauty through the display unit formed on the rear of the soundproof wall, it is possible to keep the beauty of the road always beautiful.
