Description

Soundproof wall structure {SOUNDPROOF WALL STRUCTURE}

The present invention relates to a sound barrier structure.

It should be noted that the content described in this section merely provides background information on the present invention and does not constitute the prior art.

A soundproof tunnel is a structure that reduces the noise intensity in the surrounding area below a certain standard by attenuating the noise or blocking the path in the process of transmitting the noise.

However, in the case of the prior art, since it is formed by attaching a soundproofing plate, which is a heavy object, on a steel frame such as RH-beam steel, there is a problem that the design load is insufficient due to the weight of the steel frame and the soundproofing plate.

Therefore, there is an urgent need to develop a new technology capable of reducing the weight of the soundproof tunnel unlike the prior art.
