Through adopting above-mentioned scheme, because sound is through vibrations transmission, and the transmission of vibrations needs the medium, take out approximate vacuum state between two transparent acrylic plates to can hinder the propagation of vibrations, greatly hinder the propagation of sound, thereby make the barrier have splendid syllable-dividing effect.

The utility model discloses further set up to: the periphery of transparent inferior gram force board with all coat there is the sealing tape between the shaped steel.

Through adopting above-mentioned scheme, although the sealing rubber who sets up can hinder the air leak in the vacuum layer, but the sealed effect reduces to some extent after the time has been long, so set up sealed glue and bring further sealed, further improve the leakproofness.

The utility model discloses further set up to: still the joint has the third baffle on the shaped steel support, the third baffle is located two-layerly behind the transparent inferior gram force board, just the third baffle with be provided with the water interlayer between the transparent inferior gram force board.

By adopting the scheme, although the vacuum layer is arranged between the two transparent acrylic plates, the vacuum layer cannot be completely vacuumized in the actual vacuumizing process, only one state similar to vacuum can be realized, and the transmission of vibration can be further reduced after the water separation layer is arranged, so that the sound insulation effect of the barrier is further enhanced.

The utility model discloses further set up to: the upper sound-absorbing plate and the lower sound-absorbing plate are internally provided with cavities.

By adopting the scheme and the same principle, the change of the propagation medium can reduce the conduction of vibration, thereby achieving the effect of noise reduction.

The utility model discloses further set up to: the periphery of the cavity is filled with silencing cotton.

By adopting the scheme, the noise reduction cotton is added to further reduce noise.

The utility model discloses further set up to: the upper sound-absorbing board is arc-shaped and is bent towards one side of the road.

Through adopting above-mentioned scheme, will go up the abatvoix setting and crooked to road one side, the noise that the car sent when driving on the road passes through the rectilinear propagation, and the last abatvoix of arc bending can block bigger scope, simultaneously, and at the in-process that the sound wave was reflected, the last abatvoix of arc bending can be better with the sound wave reflection to ground, the spread of noise abatement.

The utility model discloses further set up to: the upper sound-absorbing plate and the lower sound-absorbing plate are both microporous sound-absorbing plates facing one side of the road.

By adopting the scheme, the upper sound-absorbing board and the lower sound-absorbing board are arranged to be the micropore sound-absorbing boards facing to one side of a road, and when sound waves enter micropores, the sound waves are reflected in the micropores, so that the sound waves can be reduced and the noise is reduced.

To sum up, the utility model discloses following beneficial effect has: set up the multilayer acoustic celotex board and give sound insulation to set up vacuum layer and water interlayer and come the propagation of separation sound, thereby make the protective screen have splendid syllable-dividing effect.
