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.

Embodiment 1

[0030] Embodiment 1: as Figure 1 to Figure 3 As shown, a sound insulation module includes a first sound insulation board 1, a second sound insulation board 2 and a sound absorbing body 3 between the two sound insulation boards, the first sound insulation board 1 and the second sound insulation board The ends of the board 2 are covered by the groove bar 4, and the groove bar 4 overlaps and fixes the U-shaped enclosure 5 between the ends of the first sound insulation board 1 and the second sound insulation board 2, so that the whole A groove is formed at the end of the sound insulation module; the first sound insulation board 1 and the second sound insulation board 2 are wrapped with U-shaped elastic rubber bead 6; the thickness of the sound absorber 3 is 50-300 mm.

Embodiment 2

[0031] Embodiment 2 is different from Embodiment 1 in that the sound insulation module has a built-in sound insulation material wrapped in non-alkali glass fiber cloth on the outer layer of the first sound insulation board 1, and the outer layer of the second sound insulation board 2 is attached and connected with perforations The board 7 is filled with sound-absorbing material between the two sound-insulating boards, that is, it is combined into a structure of sound-insulating material-sound-absorbing material-perforated board 7, the thickness of the perforated board 7 is 1-12 mm, and the perforation rate is 23%-65% The sound-absorbing material is glass wool or melamine, and the perforated plate 7 is steel plate, aluminum plate, cement fiberboard or gypsum board, and its thickness is 5-30mm. Other structures are the same as in Example 1, and will not be repeated here.

Embodiment 3

[0032] Example 3, such as Figure 4 and Figure 5 As shown, the sound-absorbing and insulating composite structure with the embedded truss structure of the sound insulation module described in Embodiment 2 includes a truss column 9 embedded in the factory building column 8 and can be fixed to the ground, and between the bottom of the truss column 9 The well-shaped truss structure formed by the embedded bottom beam and the horizontal support truss 11 fixedly connected with the truss column 9, the groove of the sound insulation module is nested on the truss column 9 and is located between the embedded bottom beam and the horizontal Between the supporting trusses 11; the sound absorbing body 3 is fixed on the first sound insulation board 1 or the second sound insulation board 2 of the sound insulation module by screws; the outer side of the well-shaped truss structure is installed with a corrugated board armor 10; The truss column 9 is H-shaped steel with a thickness of 45-295 m...

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...
