The present invention relates to a soundproofing plate for soundproof wall installation, and more particularly, to increase the sound absorbing area and to form an air layer inside the soundproofing plate to increase the soundproofing effect.

As is well known, soundproof boards are stacked between struts installed on roads or railroad tracks to form soundproof walls to block noise generated from roads or railroad tracks. There is a reflection type where sound waves collide with each other, an interference type that causes the sound wave incident on the soundproof panel to be mixed and attenuated by the sound wave, and a resonance type that has a hole in the soundproof panel and a cavity inside so that the sound wave is attenuated by resonance. Among these, sound absorption type is the most widely used.

The sound-absorbing soundproof plate is a sound absorbing material is accommodated in a metal case usually made of a quadrilateral plate shape, the outside of the sound absorbing material is covered with a metal cover perforated in the shape of a dot or louver, the noise flows into the case through the front of the cover. The sound is absorbed and extinguished by the sound absorbing material to prevent the noise from moving beyond the soundproof wall.

In general, the sound absorbing material applied to the soundproof panel is formed by coating glass wool or polyester-based compressed fiber with a PVF (Poly Vinyl Formal) film or PE film. The cover of the soundproof panel can be configured to have a flat plate type to prevent inflow, and the sound absorbing area is narrowed, and when the sunlight is received, the cover is reflected through the cover, which may interfere with the driver's view, causing a traffic accident.

In addition, the air layer between the plate-shaped sound absorbing material and the plate-shaped cover is inevitably formed in a very narrow area, and since the rear portion of the sound absorbing material is in close contact with the case, noise is absorbed only by the sound absorbing material and the air layer having a small area. There is a problem that the soundproofing effect is reduced as a whole to be extinguished.

The present invention has been proposed in view of the above points, and the sound absorbing material is formed of a rubber material having excellent waterproofing properties, and a plurality of concave grooves are formed on the surface thereof to increase the air intake characteristics by itself, and the rear surface of the sound absorbing material is spaced apart from the case by a predetermined distance. At the same time, the cover is formed to be bulging in the front direction to form an air layer between the sound absorbing material and the case, and to provide a soundproof wall for installing the soundproof wall to maximize the soundproofing area by maximizing the area of the air layer between the sound absorbing material and the cover. .

Hereinafter, the present invention will be described in detail with reference to the embodiments presented.

That is, a plurality of holders 140 having a “c” shape in cross section and having a fixed space 141 formed in a direction facing each other at upper and lower ends thereof are supported at equal intervals on the upper and lower portions of the sound absorbing material 120, and the case 110. ) Has a "b" shape on the cross-section with the top open and the bottom closed, while the middle part has a shape formed recessed inward, and each holder 140 recesses the bottom of the case 110 and the middle of the case 110. The cover 130 is in contact with the portion 112, the upper portion of the cover 130 is bent while covering the upper portion of the case 110 and at the same time in close contact with the upper front portion of each holder 140, the extension projection 132 in the lower portion ) Is formed and the lower front portion of each holder 140 is in close contact with the lower inner sidewall while the lower end of the case 110 is fixed to the inner wall of the extension protrusion 132.

In this case, the rubber constituting the sound absorbing material 120 may be used a general rubber, but in order to further increase the sound absorbing effect, it is preferable to use chloroprene rubber (5 times foaming) excellent in mechanical properties and elasticity, and in addition to the sound absorbing effect can be increased. Any rubber material can be applied.

In addition, when the holder 140, the sound absorbing material 120, the case 110, and the cover 130 are stacked between the struts 160 in an assembled state, the extension protrusions 132 of the cover 130 are disposed on the lower portion. The upper surface of another adjacent cover 130 is stacked to cover.

In addition, the sound absorbing material 120 may be inserted into the fixing space 141 of the holder 140, and then the sound absorbing material 120 may be fixed to the holder 140 through a plurality of screws from the outside thereof. Zig-zag-shaped fixed teeth 142 are formed on the sidewalls to face each other, and thus the sound absorbing material 120 can be strongly held.

In the drawing, reference numeral 151 denotes a first space portion formed between the cover 130 and the sound absorbing material 120, and 152 denotes a second space portion formed between the sound absorbing material 120 and the case 110.

The soundproofing panel for soundproof wall installation according to the present invention configured as described above acts as follows.

First, when the cover 130 is mounted from the top in a state in which the sound absorbing material 120 having the holder 140 assembled is placed on the lower part of the case 110 and the middle recessed part 112, the upper end of the cover 130 has a multi-stage bending portion. While covering the upper part of the case 110, the front upper part is in close contact with the upper part of the front of the holder 140, and the lower end of the case 110 is located on the inner side wall of the fastening protrusion 132 formed at the lower end of the cover 130 When the lower end of the case 110 is fixed to the inner sidewall of the extension protrusion 132 by welding or the like, the lower front side of the holder 140 is in close contact with the lower inner sidewall of the cover 130, and the case 110 only has its structure. The holder 140, the sound absorbing material 120, and the cover 130 may be assembled and fixed to each other, and the sound insulation wall 100 may be formed by stacking a plurality of sound insulation plates 100 between grooves of the pillars 160 formed of H beams. .

When the noise is generated from the road in the state formed in the soundproof wall as described above is transmitted to the inside of the soundproof panel 100 through the sound wave passing hole 131 of the cover 130 to be absorbed and extinguished by the sound absorbing material 120 , The cover 130 according to the present invention is formed bulging to the front so that the noise can be easily passed inward in any direction, the sound absorbing material 120 located inside the made of a rubber material and Since a plurality of concave grooves 121 are formed on the front surface, the sound absorption area is increased, so that the noise can be more easily absorbed and destroyed.

In addition, as the cover 130 is formed bulging in the front direction, the first space 151 between the sound absorbing material 120 and the cover 130 may be formed wider, and noise may cause the cover 130 to become wider. When the resonant action in the first space portion 151 passes through it, the noise does not escape to the outside through the wide space and can be naturally extinguished.

In addition, since the second space portion 152 is formed between the rear of the sound absorbing material 120 and the case 110, the sound absorbing material 120 is elastic toward the second space part 152 when noise collides with the sound absorbing material 120. It can be acted as a better absorption of noise, even if the noise is conducted to the rear of the sound absorbing material 120 will be naturally extinguished by the resonance action in the second space 152.

On the other hand, as the cover 130 is formed bulging in the front direction, rainwater can easily flow into the inside of the cover 130, but the sound absorbing material 120 according to the present invention is made of a rubber material, so no influence of moisture Even if the cover 130 is formed to be bulging in the front direction, there are no disadvantages at all.

As described above, the present invention is to form a plurality of concave grooves on the front while the sound absorbing material is made of a rubber material, so that the sound absorbing area is increased and is not affected by moisture such as rain water at all. Even if the rainwater is easily formed by bulging, it is more advantageous to absorb and extinguish the noise through easy inflow of noise and wider space between the cover and the sound absorbing material without any influence on it, and there is a constant space between the sound absorbing material and the case. Since the sound absorbing material can be moved elastically to absorb the noise more easily, and through this space portion it is possible to extinguish the noise itself.
