Generally, soundproof walls are installed along roads, railways, and high-speed trains where noise is frequently generated. Soundproof walls are composed of a soundproof soundproof plate with a sound absorbing material built therein or a reflection soundproof plate that shields noise by reflecting the sound. Also, a composite sound insulation board having both the sound absorption type and the reflection type soundproof plate is proposed.

In the case of a sound-absorbing type soundproof wall, sound absorption by a built-in sound-absorbing material (ceraton) and blocking by a steel structure, that is, transmission loss effect are effected, whereas in the case of a reflection type reflection wall, sound waves are blocked only because there is almost no sound absorption rate of the surface. Therefore, in case of the reflection type soundproof wall, the noise of the opposite side may be increased due to the reflection effect.

These sound absorbing walls absorb sound waves, and the absorption of sound waves means that the kinetic energy of the medium particles is converted into heat energy by reducing the wave energy of the sound waves. However, the sound absorber used in the conventional sound barrier wall has a very small density and a very small transmission loss, and the ceraton has a disadvantage in that the sound absorption effect is inferior.

The object of the present invention is to provide a sound absorbing plate having a hexagonal cone-shaped sound absorbing tube and a sound insulating plate having a conical cone shape. And the sound waves flowing into the sound absorbing structure A pass through the intake port B and the wave energy is reduced to reach the sound absorbing material located in the sound absorbing space portion, the impact energy of the medium particles of the wave energy is repeatedly repeated The sound wave is canceled or converted into thermal energy, so that it is not necessary to use a sound absorbing material such as a ceraton which is inferior in sound absorbing effect, thereby providing an environmentally sound soundproofing wall.

In order to achieve the above object, the present invention has a sound absorbing plate having a hexagonal cone shape, and a sound insulating plate having a conical cone shape. The sound absorbing material is inserted into the sound absorbing plate and assembled into the assembly holes A and B, It is not necessary to use ceratons, aluminum, polycarbonate (PC), etc., which require a lot of manufacturing cost, so it is economical and environmentally friendly sound-absorbing soundproofing wall When the sound wave entering the sound absorbing unit A passes through the sound absorbing unit B and the wave energy is reduced to reach the sound absorbing material located in the sound absorbing space portion, the impact energy of the medium particles of the wave energy is repeatedly collided with the heat energy So that the sound waves are canceled or canceled.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The sound-absorbing type sound insulation wall of the present invention comprises a sound absorption plate 10 and a sound insulation plate 20, and a sound absorption material 30 is installed inside the sound absorption plate 10 and the sound insulation plate 30, The sound absorbing device ASS 'Y (100) is completed and the outer end of the sound absorbing device ASS' Y is formed with a rectangular frame 50, which is supported between the support of the sound barrier and the support And is installed and assembled in such a manner as to be fitted to the soundproof wall hitch 40.

6 is a detailed view of a sound-absorbing panel. The sound-absorbing panel 10 is injection-molded by a synthetic resin material and is coated with an anti-discoloration agent or an ultraviolet coating agent after injection to prevent discoloration from ultraviolet rays during molding. The sound-absorbing plate 10 has a hexagonal cone-shaped sound-absorbing tube 12 with a large number of hexagonal cone-shaped concave-convex portions facing inward. The sound-absorbing plate 10 is configured such that the sides of the sound- A is directed toward the inlet side of the sound wave, and the sound wave introduced into the sound absorption chamber A is introduced into the sound absorption chamber B to reduce the wavelength of the wave energy of the sound wave so that the sound absorption space B is small. I was not allowed to escape.

According to the kind of sound waves, the size of the sound absorbing members A and B can be increased or decreased to efficiently capture the high and low sounds. The shape of the sound absorbing tube 12 in the hexagonal cone shape minimizes the area where the sound waves are reflected Thereby maximizing the sound absorption effect.

The sound insulating plate 20 is injection-molded into a synthetic resin material and is coated with an anti-discoloring agent or an ultraviolet coating agent after injection to prevent discoloration from ultraviolet rays during molding. The concave and convex portions of the sound insulating plate 20 are formed in a conical shape with a large number of conical cones 22 facing inwardly. The concave and convex portions are in contact with each other to attenuate and cancel the sound waves flowing into the sound- And plays a role of fixing the sound absorbing material (30).

The sound-absorbing material 30 is installed in the sound-absorbing space of the sound-absorbing plate 10 and the sound-insulating plate 20 and is fixed by the conical irregularities of the sound-insulating plate 20.

However, there is a phenomenon that the sound absorption effect is remarkably deteriorated according to the magnitude of the kinetic energy of the medium particle of the wave energy of the incoming sound wave.

Thus, the inventor of the present invention changed the material of the sound absorbing material 30 in order, first of all, the sponge sound absorbing material 31 having the sound absorbing material particles coarse and the non-woven material sound absorbing material 32 having the smaller sound absorbing material particles, Absorbing material (33) that can be made of a porous composite sound absorbing material (33) is formed so as to cancel out sound absorption regardless of the size of the medium particle.
