Sound insulation module and sound absorption and insulation composite structure of embedded truss structure with sound insulation module

Abstract

The invention discloses a sound insulation module which comprises a first sound insulation board (1), a second sound insulation board (2) and sound absorbers (3) arranged between the two sound insulation boards or attached and connected to the surface of the first sound insulation board (1) or second sound insulation board (2). The invention also discloses a sound absorption and insulation composite structure of an embedded truss structure with the sound insulation module. The sound absorption and insulation composite structure comprises truss uprights (9) being embedded in uprights (8) of a plant and being capable of being fixed to the ground, embedded bottom cross beams between bottoms of the truss uprights (9), and a #-shaped truss structure formed by transverse support trusses (11) fixedly connected with the truss uprights (9), and grooves of the sound insulation module are embedded and sleeved on the truss uprights (9) and positioned between the embedded bottom cross beams and the transverse support trusses (11). The insulation composite structure eliminates a gap of a wall body to realize the cutting-off an acoustic bridge, and is good in wall body rigidity and simple in installation procedure.

Description

technical field [0001] The invention belongs to the field of noise control, and specifically relates to a sound insulation module and a sound absorption and insulation composite structure with an embedded truss structure of the sound insulation module. The sound insulation module and the sound absorption and insulation composite structure are especially suitable for light weight Sound insulation and noise reduction for factories, walls, and walls of civil buildings. Background technique [0002] Lightweight and high sound insulation building walls are important components to prevent noise pollution, and are widely used in civil and industrial fields. The existing light-weight and high-sound insulation building structure is mainly formed by laying light steel keels, sound-absorbing materials, gypsum boards or other sound insulation materials on site, that is, welding the light steel keel horizontally with the wall or the factory building column to form sandalwood strips. , a...

AI Technical Summary

Problems solved by technology

[0003] (1) The gap between the gypsum board and the gypsum board is inevitable, and the sealing is poor, which leads to sound leakage in the sound-absorbing and insulating wall, which leads to a significant decline in the sound insulation performance of the entire wall

[0004] (2) The inner and outer sound insulation bodies are connected by light steel keels, so there is a "sound bridge", and the sound insulation performance of the entire wall is poor

[0005] (3) Due to the insufficient rigidity of the light steel keel itself, when the cross-sectional area of ​​the wall is greater than 30 square meters, the rigidity of the sound-absorbing wall must be guaranteed by means of auxiliary beams, that is, sandalwood bars, which will increase the cost

[0006] (4) It cannot be produced in batches, and there are many laying procedures on site. When filling sound-absorbing materials, dust overflows and causes secondary pollution to the surrounding environment. The labor intensity of laying gypsum boards is high, the cycle is long, the efficiency is low, and the cost is high.
