Prefabricated wallboard of noise reduction protective separation wall

Abstract

The invention discloses a prefabricated wallboard of a noise reduction protective separation wall, and belongs to the technical field of protective separation walls. The prefabricated wallboard of thenoise reduction protective separation wall comprises a partition board, the partition board is formed by sequentially bonding a horn sound absorption layer, an inner protective layer, an elastic noise reduction layer, a vacuum isolation layer, a shock absorption and noise reduction layer and an outer protective layer, dense bidirectional horn structure holes are formed in the horn sound absorption layer, each bidirectional horn structure hole is a through hole formed by sequentially connecting a wide-mouth horn hole, a straight cylinder hole and a narrow-mouth horn hole, the elastic noise reduction layer is made of an elastic rubber sheet, the vacuum isolation layer is a vacuum cavity body formed by sealing a hard sponge plate with a sealing material and then vacuum-pumping, and the shockabsorption and noise reduction layer is made of a glass wool substrate. According to the structural wall body formed by sequentially bonding an inner layer and an outer layer on the whole, noise sound waves generated on a construction site can be absorbed and transmitted into the wall body, then the noise sound waves are integrally transmitted to the elastic noise reduction layer through an innerprotection layer for primary relieving, residual noise is isolated through the vacuum isolation layer, finally, the residual noise is absorbed and eliminated through the shock absorption and noise reduction layer, and therefore the noise sound waves can be effectively eliminated on the 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 social 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 periphery of the entire building construction or outside the partial construction site. The partition wall surrounds the construction area and plays the role of warning protection to avoid accidents. [0003] However, in the process of building construction, it is necessary to use large-scale machinery to process materials such as sand, gravel and cement. During the construction process, a large amount of dust and noise are often generated. The dust is generally treated by spray tools and dust-proof nets, but the noise is invisible. Y...

Problems solved by technology

[0005] Although this solution can reduce the noise to a certain extent, the effect is very limited, especially the structure of the buffer spring and the buffer block can touch very little noise, and the noise without contact cannot be reduced or eliminated
