Abstract

A prefabricated wall panel for a noise-reducing protective partition wall, belonging to the technical field of protective partition walls, including a partition wall panel, the partition wall panel is composed of a horn sound-absorbing layer, an inner protective layer, an elastic noise-reducing layer, a vacuum isolation layer, and a shock-absorbing sound-absorbing layer It is bonded with the outer protective layer in sequence; the sound-absorbing layer of the horn is provided with dense two-way horn structural holes, and the two-way horn structural holes are sequentially connected by wide-mouthed horn holes, straight cylindrical holes and narrow-mouthed horn holes The through hole formed; the elastic noise reduction layer is made of elastic rubber sheet; the vacuum isolation layer is a vacuum cavity made by sealing the hard sponge board with a sealing material and then vacuuming; the shock absorption and noise reduction layer It is made of glass wool substrate; this kind of structural wall, which is bonded sequentially from the inner layer to the outer layer as a whole, can absorb the noise and sound waves generated on the construction site and propagate into the wall, and then the inner protective layer as a whole It is transmitted to the elastic noise reduction layer for initial mitigation, and then the remaining noise is isolated by the vacuum isolation layer, and finally absorbed and eliminated by the shock absorption and sound-absorbing layer, which can effectively eliminate noise sound waves as a whole.

Description

technical field [0001] The invention relates to the technical field of protective partition walls, in particular to a prefabricated wall panel for noise reduction protective partition walls. Background technique [0002] With the rapid development of society and economy, urban building construction is often carried out in a large area. In the process of building construction, for safety reasons, protective partition walls are often built around the entire building construction or outside of some construction sites. The partition wall surrounds the construction area and acts as a warning and protection to avoid accidents. [0003] However, in the process of building construction, large-scale machinery needs to be used to process materials such as sand, gravel and cement. A large amount of dust and noise are often generated during the construction process. The dust is generally treated by spray tools and dust-proof nets, but the noise is invisible However, the sound insulatio...
