Cavity-type common vibration sound absorption board wall structure and construction method

Abstract

The invention discloses a cavity-type common vibration sound absorption board wall structure and construction method. The structure comprises a wall body, an I-beam layer, a steel wire net and a light steel dragon skeleton from inside to outside, wherein a plurality of spring isolators are arranged between the wall body and the I-beam layer, the wall body is provided with a plurality of embedded parts, and both ends of each spring isolator are fixedly connected with the embedded parts and the I-beam layer respectively; the I-beam layer comprises a plurality of vertical I-beams arranged along the surface of the wall body in order, and the I-beam layer is fixedly connected with the light steel dragon skeleton through a fixing device; a shock absorbing rubber pad is arranged between the bottom of the I-beam layer and the ground, and a cement sound insulation board is arranged between the light steel dragon skeleton and the ground; the lattice of the light steel dragon skeleton is stuffed with environment-friendly and waterproof sound absorbing cotton, and the sound absorbing cotton is wrapped with sound absorbing nonwoven fabrics; a sound absorbing board is fixed on the outer side of the sound absorbing non-woven fabrics, and a fireproof board is arranged on the light steel dragon skeleton. The cavity-type common vibration sound absorption board wall structure has the advantages of a good sound insulation effect, a wide sound absorption range, small environmental pollution, convenient construction, a high utilization ratio of unit material, high overall cost performance, and energy saving and environmental protection.

Description

technical field [0001] The invention belongs to the field of building construction, and in particular relates to a cavity-type resonant sound-absorbing panel wall structure and a construction method. Background technique [0002] With the development of social economy and culture, other public places such as vocal music art training, education, entertainment, and sports venues have higher requirements for the sound absorption effect of venues. Therefore, how to improve the sound absorption structure of the wall and reduce noise control is the current music. Halls, theaters, recording studios, conference rooms, multi-function halls, hearing rooms, studios, gymnasiums and auditoriums and other public buildings urgently need to be solved. [0003] At present, the method of improving the sound absorption effect of the wall is mainly by changing the sound-absorbing cotton and the sound-absorbing structure. Mineral fiber sound-absorbing cotton is brittle during construction and i...

AI Technical Summary

Problems solved by technology

Mineral fiber sound-absorbing cotton is brittle during construction and installation, and it is easy to break to form dust and pollute the environment, and the soft surface needs to be protected and decorated, such as perforated panels and breathable fabrics. The structure is relatively complex and the volume Large, troublesome storage and transportation; most of the current sound-absorbing structures have narrow sound-absorbing frequency bands, expensive construction, complicated construction, and poor fire resistance. Improve the sound-absorbing cotton on the wall and the sound-absorbing structure to optimize the remaining space
