This is to prevent noise from leaking out.

That is, when the soundproof plate 100 is coupled between the support posts 220, a gap of a certain interval occurs due to the shape of the support between the lower surface of the soundproof board 100 and the upper surface of the base portion 210. Some of the noise generated may be transmitted to the residential area through the gap, the sound insulation block 230 is essentially installed between the sound insulation plate 100 and the base portion 210 to block the transmission of noise.

The existing sound insulation block is simply installed so that its upper surface is formed with a flat surface and fits in the gap between the sound insulation plate and the foundation, so that the sound insulation plate is prevented by external force transmitted to the sound insulation wall, for example, wind or vehicle shock generated from the vehicle. In case of shaking, it was easily released from the gap.

Next, after forming the coupling groove (100A) having a shape corresponding to the coupling protrusion 232 in the longitudinal direction on the lower surface of the soundproof plate 100, both sides of the soundproof plate 100 is fitted into the fitting groove 222 The coupling groove 100A is coupled to the support 220 to be coupled to the coupling protrusion 232 of the sound insulation block 230 to complete the construction of the soundproof wall 200.

As described above, when the soundproof wall 200 is constructed, the coupling groove 110A of the soundproof plate 100 and the coupling protrusion 232 of the soundproof barrier 230 are mutually coupled to each other so that the soundproof barrier material 230 is separated from the soundproof wall 100. It is possible to prevent the departure.

And, the soundproof wall 200 using the soundproof plate having a prefabricated sound-absorbing block, as shown in Figure 13, when installing a plurality of soundproof panels 100 stacked between the struts 220, is located in the upper end of the soundproof wall 200 The soundproof plate 100 may have a sound absorbing block 130 of a shorter length from the upper region to the lower region.

Accordingly, the sound insulation plate 100 located at the upper end of the soundproof wall 200 has a sound diffraction phenomenon and reflected wave and complex sound interference when noise is transmitted to the soundproof wall 200 by the arrangement of the sound absorbing block 130. By reducing the sound energy, it has the same function as the noise interference device that is provided to reduce the noise by the sound interference in the existing soundproof wall, so that the noise can be reduced without the noise reduction device.

In addition, the soundproof wall 200 using the soundproof plate having a prefabricated sound absorbing block, as shown in FIG. 14, is located at the upper end of the soundproof wall 200 when a plurality of soundproof panels 100 are stacked and installed between the support posts 220. The soundproof plate 100 may have a sound absorbing block 130 having a shorter length from the middle region to the upper and lower regions.

Accordingly, the sound insulation plate 100 located at the upper end of the soundproof wall 200 has a negative diffraction phenomenon as in the above-described embodiment, when noise is transmitted to the soundproof wall 200 by a complicated arrangement of the sound absorbing block 130. Since the sound energy is reduced by the reflected wave and the complex sound interference, it is unnecessary to install a noise interference device to reduce the noise.

In addition, the soundproof wall 200 using the soundproof plate having a prefabricated sound absorbing block, as shown in FIG. 15, when a plurality of soundproof panels 100 are stacked and installed between the struts 220, is located at an upper end of the soundproof wall 200. The soundproof plate 100 may be disposed such that sound absorption blocks 130 of the same length or different lengths protrude irregularly between the upper and lower regions.

Accordingly, the sound insulation plate 100 located at the upper end of the soundproof wall 200 has a negative diffraction phenomenon as in the above-described embodiment, when noise is transmitted to the soundproof wall 200 by a complicated arrangement of the sound absorbing block 130. By reducing the sound energy by the reflected wave and the complex sound interference, it is possible to replace the noise reduction device installed in the existing soundproof wall.
