Description

Technical Field

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

[0002] The metal sound barrier is a barrier made of metal materials for isolating sound. It is usually used in industrial fields, beside roads and other places that require sound insulation. The metal sound barrier can effectively reduce the spread of noise, provide a quieter environment and protect people's health. The material of the metal sound barrier is usually aluminum alloy or steel, because these materials have good strength and durability and can be used for a long time in outdoor environments. The structural design of the barrier can effectively reduce the spread of sound through reflection, absorption and isolation, and play a role in sound insulation. There are at least the following disadvantages in the use of existing metal sound barriers: Existing metal sound barriers are often placed between two mounting frames and then fastened with screws. This installation method is cumbersome and consumes a lot of screws. Once the screws are rusted, the connection between the metal sound barrier and the mounting frame will be unstable and shake. Therefore, we have introduced an interlaced metal sound barrier. Utility Model Content
