In general, in the case of railroads, airfields, roads, etc., soundproof walls are installed to block noise from driving by vehicles or takeoff and landing of airplanes to residential areas, and it is mandatory to install soundproof walls in places where noise is high.

The soundproof wall may be divided into a reflection type soundproof wall that blocks noise from propagating to the outside of the road by reflecting noise generated on the road back to the road, and a sound absorbing type soundproof wall that absorbs and extinguishes noise generated on the road. The reflective soundproof wall is inexpensive, but has a low noise blocking effect, so a sound absorbing soundproof wall with excellent noise effect is widely used on the roadside.

The soundproof wall of the sound absorbing type uses a principle of absorbing noise generated on the road through the sound absorbing material and reducing noise through resonance inside the cavity by absorbing sound or the like inside the block.

The general configuration of the soundproof wall is to place the struts at regular intervals on the roadside, and install the soundproof plates by stacking them from the top to the bottom between the corresponding pair of adjacent struts, to prevent the soundproof plates from falling off and scattering when colliding with a vehicle, etc. In order to install the wire between the upper and lower sound insulation boards, it is installed.

The method of stacking the sound insulation plates downward between the pair of props is difficult and expensive because the soundproof plates located above the damaged soundproof plates must be lifted and sequentially separated from the props in order to replace the damaged soundproof plates, and the soundproof plates must be replaced. It takes a lot of time, and the wire is corroded over time, and there is a problem that the soundproof plate is separated and scattered when colliding with a vehicle.

In order to solve the above problems, Korean Patent Registration No. 10-0891464 'Soundproof Wall' is disclosed. This prior art is "a room consisting of a plurality of soundproof plates 20 installed between the pillars 10 and the H beam-shaped upright at regular intervals,

(See claim 1) As a soundproof wall construction, it is not necessary to install soundproof plates sequentially from the bottom to the top using heavy equipment. It is possible to install the soundproof plate from the desired position only, and by providing a slider base and a slider on the soundproof wall installation post, the soundproof plate can be easily assembled and disassembled on the post by disposing the soundproof plate on the slider and adhering to the left or right. The purpose is to provide.

However, the prior art is composed of a slider base 30, a guide rail 40, a compression spring 50, a slider 60, etc. in a configuration that supports the soundproofing plate 20. There is a problem that the cost increases.

In addition, the prior art has a problem in that the soundproof plate 20 is not coupled to the support 10, so that when an impact is applied to the soundproof plate, it may escape, resulting in a safety accident.
