Problems solved by technology

[0003] The existing sound-proof glass is generally hollow type, but although the hollow glass can effectively block a lot of outdoor noise, part of the noise can still be transmitted to the room through the solid-air-solid method, which will have a certain noise impact on the room. Improve the sound insulation and noise reduction effect of double-layer glass panels, and further reduce the amount of noise transmitted to the room, which has become the problem to be solved in this application

Embodiment 1

[0029] see figure 1 , figure 2 , the soundproof cavity G is equipped with an outer PVC support plate 3 on one side of the outer glass 1; the soundproof cavity G is equipped with an inner PVC support plate 4 located on the inner glass 2 side; the outer PVC support plate 3 and An outer sound guide plate 7 located on one side of the outer PVC support plate 3 is arranged between the inner PVC support plates 4; The inner sound insulation board 8.

[0030] see image 3 , Figure 4 , the outer PVC support plate 3 is provided with a number of first retracted wide openings 301; one side of the outer sound guide plate 7 is embedded with a reflective surface 9 matching the position of the first retracted wide mouth 301; the outer sound guide plate The upper and lower ends of 7 are provided with a number of second end wide openings 701; the inner sides of the upper and lower ends of the outer sound guide plate 7 are fixedly connected with a first upper sound-absorbing plate 702 and a...

Embodiment 2

[0036]In the present invention, after the external noise passes through the outer layer of glass, part of the noise lingers between the outer layer of glass 1 and the outer PVC support plate 3, and part of the noise passes through the outer PVC support plate 3 and the first inner contraction on the outer PVC support plate 3. The port 301 enters the outer PVC support plate 3 and the outer sound guide plate 7, and the reflective surface 9 on the outer sound guide plate 7 is reflected, and part of the noise sound waves are gradually reflected into the second end wide mouth 701 at the upper and lower ends. Sound waves directly enter the interior of the first upper sound-absorbing plate 702, the third upper sound-insulating absorbing plate 801, and the first lower sound-insulating absorbing plate 703; part of the sound waves are blocked by the reflection of the third upper sound-proof light panel 802, and finally by the oblique The slot 10 enters the first upper sound-absorbing plat...

Abstract

The invention discloses inner layer folding type noise-reducing sound-insulating glass and relates to the technical field of glass sound insulation. According to the glass, an inner-side sound insulation plate located at one side of an inner-layer PVC supporting plate is arranged between an outer-side PVC supporting plate and the inner-layer PVC supporting plate; the outer-side PVC supporting plate is provided with a plurality of first retracted wide openings; a light reflecting surface matched with the first retracted wide openings in position is arranged at one side of an outer-side sound guide plate in an embedded mode; the upper end and the lower end of the outer-side sound guide plate are respectively provided with a plurality of second end wide openings; and the inner side of the upper end of the outer-side sound guide plate is fixedly connected with a first upper sound insulation and absorption plate and a first lower sound insulation and absorption plate, and the inner side ofthe lower end of the outer-side sound guide plate is fixedly connected with a first upper sound insulation and absorption plate and a first lower sound insulation and absorption plate. According to the glass, a sound insulation cavity without vacuum is formed between an inner glass layer and an outer glass layer, the PVC supporting plates and the sound insulation plates are arranged in the sound insulation cavity, a sound insulation structure with multidirectional reflection and noise reduction functions is arranged between the inner sound insulation plate and the outer sound insulation plate,and the sound insulation and noise reduction effects between the double-layer glass plates is improved by adopting the multidimensional design of sound insulation and absorption from outside to inside.

Description

technical field [0001] The invention belongs to the technical field of glass sound insulation, and in particular relates to an inner folded noise reduction and sound insulation glass. Background technique [0002] With the continuous development of society, the problem of noise pollution is becoming more and more serious, especially the noise of traffic and construction production in the city is constantly troubling the general public. Sound-proof glass is a glass product that can shield the sound to a certain extent. Usually It is double layer. For laminated glass with multi-layer composite structure, the sound insulation and damping glue (film) in the middle of the laminated glass plays a key role in the weakening and attenuation of sound transmission. Glass products with sound insulation function include laminated glass. [0003] The existing sound-proof glass is generally hollow type, but although the hollow glass can effectively block a lot of outdoor noise, part of th...
