Description

Technical Field

[0001] The utility model relates to the technical field of sound barriers, in particular to an anti-collision sound barrier. Background Art

[0002] Sound barriers are mainly used for sound insulation and noise reduction on roads, highways, elevated composite roads and other noise sources. They are divided into pure sound insulation reflective sound barriers and sound absorption and sound insulation combined composite sound barriers. The latter is a more effective sound insulation method.

[0003] The utility model with the announcement number CN215669109U discloses a novel anti-collision sound barrier, which includes columns arranged at a certain interval and a transparent screen body arranged between adjacent columns, and also includes a steel wire rope, at least one end of the left and right ends of the transparent sound insulation board is fixedly connected to the left and right aluminum profiles through the steel wire rope;

[0004] The above technical solution is fixed to the anti-fall structure at both ends by steel wire ropes. After being hit, since the steel wire ropes themselves are not very tight or a certain margin is reserved, they are not subjected to force at the moment of impact. The force will gradually increase when the transparent sound insulation board falls out after the impact, which prolongs the buffer time and reduces the force on both ends of the transparent sound insulation board. Therefore, it will not fall out of the column, avoiding falling on the road surface to cause secondary damage, and has great promotion and application value; however, the sound barrier is susceptible to contact collision damage during placement, causing damage to the whole, losing noise reduction and sound insulation, and has no anti-collision protection. In addition, the sound screen is used for a long time, which is not convenient for rapid maintenance and replacement operations. Utility Model Content
