The sound barrier is mainly used for noise insulation and noise reduction on highways, expressways, elevated composite roads and other noise sources.

[0003] In the prior art, sound barriers are installed where there are houses around highways. The sound barriers are used to reduce the noise caused by vehicles running on the highway, so as to protect the surrounding residents from the impact of noise. Although the existing sound barriers can isolate noise very well, the connection parts are prone to loosening due to long-term vibration when vehicles pass through the highway, resulting in reduced sound insulation and noise reduction effects. Therefore, we propose a sound barrier for highways. Utility Model Content

The term "and / or" used in this article includes any and all combinations of one or more related listed items. Example

[0025] like Figure 1-5As shown, the utility model provides a technical solution: a sound barrier for highways, including symmetrically set columns 1 with arc-shaped tops, connection grooves 2 are provided on both sides of the columns 1, and a plurality of fixing holes 3 are provided through the connection grooves 2 on both sides of the front of the columns 1, and an extruded plate 4 made of an aluminum plate with an arc-shaped top is also installed near the back of the connection groove 2, and a plurality of spring dampers 5 are installed on the back of the extruded plate 4, and the extruded plate 4 can be effectively supported by the spring dampers 5, and fixing blocks 6 are installed at the bottom of the front and back of the columns 1, and fixing parts 7 are installed on the top of the fixing blocks 6. Example

[0026] like Figure 1-5 As shown, an elastic pad 41 made of silicone material is bonded to the front of the extruded plate 4, and the interior of the extruded plate 4 is filled with a first sound insulation layer 42. The first sound insulation layer 42 is filled with sound insulation cotton. The first sound insulation layer 42 can effectively ensure the noise isolation effect at the connection.

[0027] A number of limiting grooves 51 are correspondingly provided on the periphery of the spring damper 5 and on the back side of the connecting groove 2, and further a number of extrusion rollers 52 are installed on the front side of the spring damper 5 and on the back side of the extrusion plate 4. The extrusion rollers 52 are fixedly connected to the spring damper 5, and the extrusion rollers 52 are fixedly connected to the extrusion plate 4. The spring damper 5 and the extrusion rollers 52 can effectively provide extrusion force for the extrusion plate 4, so that it fits on the isolation plate 8 and the frame 85, thereby ensuring the sound insulation effect.

[0028] Isolation plates 8 are installed at the top and bottom of the connecting groove 2 relative to the column 1, and a plurality of sound-absorbing grooves 81 are opened on the front of the isolation plate 8, and a dust-proof net 82 is installed on the back of the sound-absorbing groove 81 and inside the isolation plate 8. The dust-proof net 82 is bonded to the inside of the isolation plate 8. The isolation plate 8 is made of aluminum plate material. Through the sound-absorbing groove 81, the noise can be effectively allowed to enter the second sound insulation layer 83 and be absorbed by it.

[0029] The interior of the isolation board 8 and the back side of the dustproof net 82 are also filled with a second sound insulation layer 83, and a rock board 84 is installed on the back side of the second sound insulation layer 83. The rock board 84 has good support and can effectively achieve sound insulation effect.

[0030] A frame 85 is installed on the side opposite to the isolation plate 8, and a double-layer soundproof glass 86 is sealed and installed on the side opposite to the frame 85. The frame 85 is made of aluminum plate material, and the double-layer soundproof glass 86 has a good noise isolation effect.

[0031] The working process of the utility model is as follows: when a sound barrier for a highway is used for noise isolation, first, when a vehicle is traveling on the highway, the noise generated by the vehicle is transmitted to the column 1 and between the isolation plate 8 and the double-layer soundproof glass 86, and the noise will be isolated and absorbed by the double-layer soundproof glass 86 and the frame 85, and the noise part transmitted to the isolation plate 8 is absorbed by the isolation plate 8, while the other part enters the interior of the isolation plate 8 through the sound-absorbing groove 81 and is absorbed by the second sound insulation layer 83 and the rock plate 84. When the car brings vibration, the spring damper 5 in the connecting groove 2 on both sides of the column 1 will effectively reduce vibration, and the extrusion plate 4 is squeezed by the extrusion roller 52, so that the elastic pad 41 on the extrusion plate 4 fits the connection part through the extrusion, so as to prevent the connection part from generating gaps due to vibration and causing noise, and the extrusion plate 4 and the first sound insulation layer 42 can also effectively absorb noise to prevent people around from being affected by noise. The utility model can effectively ensure that the connection part of the sound barrier will not be loosened, resulting in poor sound insulation and noise reduction effect, effectively ensuring the effect of sound insulation and noise reduction, and avoiding noise interference to surrounding residents.

[0032] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
