Windproof sound insulating plate

Abstract

The invention provides a windproof sound insulating plate. The windproof sound insulating plate comprises a front plate body and a rear plate body, wherein the front plate body and the rear plate bodyare arranged side by side. Multiple front sound holes are formed in the front plate body, the front sound holes penetrate through the front face of the front plate body, each front sound hole communicates with a front containing cavity, and the front containing cavity penetrates through the back face of the front plate body. Multiple rear sound holes corresponding to the front sound holes one toone are formed in the rear plate body, the rear sound holes penetrate through the back face of the rear plate body, each rear sound hole communicates with a rear containing cavity, and the rear containing cavity penetrates through the front face of the rear plate body. The front containing cavity and the rear containing cavity correspondingly communicate to form a cavity, sound absorption cotton particles are arranged in the cavity, and the volume of the sound absorption cotton particles is smaller than the capacity of the cavity. The windproof sound insulating plate achieves sound insulatingand micro-ventilating effects at ordinary times and achieves the windproof effect when wind springs up.

Description

technical field [0001] The invention relates to the technical field of sound insulation, in particular to a windproof and sound insulation board. Background technique [0002] It is well known that functional equipment installed in cement buildings or factory workshops will emit relatively loud noises, and it is common for people to install equipment with relatively loud noises and temporary work sheds outdoors near households; in order to reduce noise interference, usually in A sound insulation board is installed near the equipment "with or without a ceiling". The sound insulation board can reduce the noise and reduce the interference caused by the resonance frequency of the sound wave. The known sound insulation board has the difference between the air sound and the vibration sound. The main sound insulation structure used is It is realized by using blind holes of different apertures or reducing the density of objects, among which the more common ones are single light damp...

AI Technical Summary

Problems solved by technology

[0003] However, the above-mentioned sound insulation panels have sound insulation effects but lack micro-ventilation effects during use, such as temporary sheds on construction sites, temporary dormitories for workers in field construction, and protection equipment from rain and ventilation. These buildings not only need to have better sound insulation effect, it is also necessary to have a ventilation function and to avoid the entry of dust brought by strong winds
