Abstract
Description

[0002] Sound barriers are widely used in urban transportation, industrial production, and other fields as an important facility for controlling noise pollution. Traditional prefabricated sound barriers are usually assembled using components of fixed specifications, and key components such as perforated aluminum panels have significant limitations in the assembly process. The aluminum panel connection structure of existing sound barriers is relatively simple, often making it difficult to flexibly adjust the number and size of perforated aluminum panels according to actual usage scenarios and noise reduction requirements. When it is necessary to increase the area of the sound barrier to enhance the noise reduction effect, it is not easy to extend the assembly, thus limiting its application scenarios.
[0003] Furthermore, existing perforated aluminum plate connection methods are insufficient in terms of stability. Common connection structures, lacking effective limiting and clamping measures, are prone to loosening and separation due to external vibrations, wind, and other factors during use. This not only affects the noise reduction performance of the sound barrier but may also pose safety hazards, increase maintenance costs, and increase replacement frequency. Utility Model Content
