Description

{Soundproof wall with Sound Absorption Panel}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a soundproof wall for protecting a residential and work space from noise, installed on a road, a railroad track, or a stadium, and more particularly to a sound absorbing panel The present invention relates to a soundproof wall capable of exhibiting an excellent sound absorption and sound effect as well as a beautiful decoration effect by combining various decorative members and a wood block plate on the front and back surfaces of the wooden frame.

Generally, soundproof walls are installed for the purpose of reducing or extinguishing noise at places where noise is generated such as roads, railways, airports, factories, etc. In the runways of roads or airports, they are installed in parallel to the noise- The noise source is sealed or enclosed in the closed place to prevent noise leakage from the outside.

Such a soundproof wall is mainly intended to block noise, and therefore, it is installed between a place where a person hears the noise at a place where noise is generated, and a large sound barrier wall installed next to a road or a railway. Since the sound is transmitted in the form of waves, it is common to increase the height of the sound barrier or increase the thickness of the sound barrier considering the motion law of the waves. It is also made using special soundproofing materials that can absorb sound waves.

These soundproof walls are made considering the 'noise point', which is the place that receives the most noise, and the sound absorption rate of how much sound can be absorbed during manufacturing, the permeability of how much the noise passing through the wall is reduced Loss and insertion loss of how much decibel value is reduced after installation of the soundproof wall, etc. In Korea, the soundproof wall is manufactured or installed according to the standard notified by the Ministry of Environment. In recent years, And safety aspects are also considered.

These soundproofing walls not only cut off the noise but also cut off the exhaust gas of the vehicle and prevent the inside of the neighboring building from being exposed and also play a role of protection of personal privacy, By eliminating elements that can lead to major accidents, it can also play a role in stabilization.

The soundproof panel applied to the soundproof wall or the soundproof wall as described above is integrally formed with a soundproof panel having a plurality of inlets by inserting into the support frame to form a flat wall surface as in the Utility Model Registration No. 20-0212289 A soundproof panel assembly has been developed and registered so as to effectively absorb noise and improve the sound absorption rate and the sound insulation effect.

Further, a panel body having an opening on one side and having two or more accommodating spaces therein as in the case of Japanese Patent No. 10-1128390; A sound absorbing material installed in a receiving space of the panel body; And a cover having a plurality of sound absorbing holes coupled to the opening of the panel body, wherein the panel body has an upper extension extending horizontally at the upper end thereof, a lower extension extending horizontally at a lower end thereof, And the sound absorbing material is separated from the inner wall surface of the panel body to form a circulation space for noise, and the circulation space is limited by the inner wall surface of the panel body and the sound absorbing material And a soundproof panel having a cover having a plurality of sound absorbing holes and a protruding portion extending in the longitudinal direction at a central portion of the cover.

Further, in the soundproof panel having the sound absorbing function as in the registered utility model No. 10-0473052, the vertical and horizontal reinforcing members can be inserted and the casing formed with the double wall is provided, A soundproof panel integrated with a casing, a lower casing, and a side frame formed integrally and easy to construct has been proposed and registered.

Also, as disclosed in Japanese Patent Application No. 10-1490011, there are two first strut frames positioned in parallel at regular intervals and a second strut frame interconnected along the two first strut frame centers, A soundproof panel disposed between the adjacent struts and disposed outside one of the first and second strut frames; and a soundproof panel disposed between the two adjacent struts, The installation structure of the soundproof panel including the wind pressure adjusting installation means for reducing the moving speed and impact of the soundproof panel as well as restoring the soundproof panel when the soundproof panel is moved by wind pressure has been enacted and registered.

However, existing soundproof walls have problems such as troublesomeness in manufacturing, difficulty in handling due to weight, or shortening of service life due to lowering of durability, which is inserted into a pillar installed at regular intervals.

That is, in the case of a soundproof panel having a frame structure made of a metal body, although it is excellent in durability, it has a problem in that it is very difficult to construct and handle since it is a heavy body. In the case of a soundproof panel having a frame structure made of synthetic resin, Of course, the soundproofing and sound absorbing effect is relatively low, and discoloration, hardening corrosion and the like are caused, and thus the service life is very short.

In addition, a soundproof panel made of wood or glass is also applied. However, the soundproof panel made of wood is excellent in sound absorption and soundproofing effect, but the wood is twisted or cracked at the time of installation for a long time. In the case of a soundproof panel made of glass and the like, although excellent visibility is obtained, sound insulation and sound absorbing effect are small, and breakage due to shock or vibration frequently occurs, resulting in frequent replacement and maintenance.

In particular, the existing soundproof panels and the soundproof walls resulting therefrom are mostly developed for soundproofing, sound absorption and sound insulation, and there is a problem of damaging a large part of the city aesthetic due to a very high and thick soundproof wall.
