Description

Soundproof wall {sound proof wall}

The present invention relates to a soundproof wall, and more particularly, to a soundproof wall which can effectively reduce working time and expenditure for installing the soundproof wall, and can effectively repair and maintain the soundproof panel, To a soundproof wall structure that can be made to be made.

Generally, a structure such as a sound barrier is installed on a railroad, a road, a road, a residential area, or the vicinity of a school in order to block noise generated from a railroad, a vehicle on a road, and external facilities.

For example, the soundproof wall may be formed by installing H-beam type struts upright at a predetermined interval and fixing them with an anchor bolt or the like on a ground or floor surface, and sequentially inserting a plurality of soundproof panels between the struts, .

At this time, a transparent panel made of a transparent plastic material is used between the soundproof panels in order to secure a wide field of view and improve the appearance of the city in the process of installing the soundproof wall.

However, since the upper and lower ends of the soundproof panel are formed obliquely, the upper and lower ends of the transparent panel are formed in a horizontal plane, so that a gap (space) is formed between the soundproof panel and the transparent panel, The soundproof effect is deteriorated and the bonding force between them is weak, and there is a possibility that the soundproof wall is damaged by external action such as strong wind.

Accordingly, techniques for enhancing the bonding force between the soundproof panel and the transparent panel and improving the noise shielding effect have been proposed variously as described in the [prior art document].

However, since most of the soundproof walls according to the related art are vertically installed with components such as soundproofing panels in a sliding manner, when a soundproof panel needs to be replaced due to deterioration or breakage of the soundproof panel, There is a problem that the whole is disassembled and needs to be repaired.

In other words, the conventional soundproofing wall is inferior in workability on the construction work, and it is necessary to disassemble the entire soundproofing wall and perform maintenance for the necessary repairing points, There are many problems such as time consuming and lowering of working efficiency.

On the other hand, in the case of a structure that can be easily detached from the soundproof wall according to the related art, there is a structural problem that the soundproofing member is detached from the soundproof wall due to strong wind or the like, and the durability and robustness of the soundproof wall are weakened.
