The present invention relates to a soundproof wall, and more particularly, in order to improve the structure of the soundproof wall stacked on both ends of the H beam, fixing means are installed on the front surface of the rear plate coupled to both ends of the H beam, and between the H beam and the H beam. Protrudes, the front plate is slide-bonded and separated on the inner surface of the fixing means relates to a soundproof wall to easily replace the front plate and the sound absorbing material without separating the soundproof plate from the H beam to reduce maintenance costs.

In general, sound barriers are installed at the edges of roads to reduce noise and create a pleasant road environment in noisy places such as railways, airfields, and roads. The soundproof wall has a structure in which a sound absorbing material made of glass wool or polyester is inserted therein and is entirely composed of a front plate and a rear plate and a side frame is coupled to the side. Such a sound barrier is a situation in which two types of sound-proof holes are formed in the inside of the front plate, and a predetermined size of the sound absorbing holes are formed therein, or the inner surface of the front plate has a sound absorbing hole inclined downward.

The soundproof wall is inserted into the H beam in a stacked manner, and when the soundproof wall is used for a long time, the sound absorbing material formed inside the soundproof wall is corroded or dust is generated, resulting in environmental pollution.

If the sound absorbing material is used for a long time, the sound absorbing material falls down from the inside of the soundproof wall due to external environmental factors and its own weight, and the sound absorbing property is limited.

Meanwhile, in order to replace the sound absorbing material, the sound absorbing wall inserted into the H-beam is completely separated, and then the sound absorbing material is replaced by separating the front plate, the back plate, the side frame and the top plate. A little bit different.

However, lifting all the sound barriers installed inside the H-beams and then removing the individual components coupled to the sound barriers are all applied equally, which requires a lot of equipment, manpower and time for maintenance work to replace the sound absorbing material. Therefore, there was a problem that excessive maintenance costs.

In addition, since the structure of the soundproof wall is not the same, it takes a lot of work time for disassembling and assembling the soundproof wall, and the overall work process is delayed, resulting in trouble in construction.

In addition, if the vehicle is damaged due to contact with the sound barrier, the troublesome has to separate all the sound barriers stacked on the H beam in order to replace the damaged sound barrier, and the side frame is inserted inside the H beam, and usually only the front plate is damaged. If the front plate and the side frame is in close contact, or integrally formed soundproof wall has to replace the entire soundproof wall, there was also a problem that takes too much replacement cost.

In order to secure the above problems, in recent years, a soundproof wall that can separate the front plate without separating the soundproof wall from the H beam has been pre-registered. It is formed of a frame member 310, the front plate 320 and the rear plate 330 coupled to the front and rear surfaces of the frame member 310 by a bolt 340, the sound absorbing material inside the frame member 310 It is made of a structure in which the 200 is installed so that the boat 340 fixed to the front plate 320 and the rear plate 330 in a state installed on the H beam can be used.

On the other hand, when the front panel 320 is damaged by an external impact, if the bolt 340 is twisted or damaged, the separation work of the boat 340 is difficult, and thus the inconvenience of requiring a long time for maintenance. have.

And, since work takes a lot of time for fastening and separating the bolt 340 coupled to the front plate 320 and the frame member 310, the workability is inferior, and the fastening of the bolt 340 is loose. The front plate 320 may also cause noise to be shaken.

In addition, the front plate 320 has to be replaced because the front plate 320 is aged when used for a long time, so that the performance of the soundproof panel is degraded. At this time, the bolt 340 and the frame member 310 which fix the front plate 320 are fixed. Even the nut hole of the) is aging and the fastening of the bolt 310 is not firm, so even if the front panel 320 is replaced, the front panel 320 is loosely fixed and a strong wind blows the risk of an accident. Because of this, there is a problem in that the entire soundproof panel needs to be replaced, and thus the maintenance cost is excessive.

The present invention has been made in view of the above-described conventional problems, and an object thereof is a fixing means is installed on the front surface of the rear plate to which the H beam is coupled, and the fixing means is formed to protrude a predetermined length in front of the inside of the fixing means. The front plate is coupled to and separated by a slide method on the side to provide a soundproof wall for easy repair and replacement of sound absorbing material.
