Description

Bending noise reduction glass with high transparency

Technical Field

The utility model belongs to the technical field of making an uproar, concretely relates to glass of making an uproar falls in curved system with high transparency.

Background

Along with the rapid development of the modern and urbanized construction of our country, the city is flourishing day by day, the number of airplanes, trains and automobiles is increased rapidly, and the traffic noise is more serious. The noise is transmitted into the room through the door and window, and can harm the physiological health and mental state of people in serious cases, and reduce the life and the working quality of people. Therefore, the soundproof glass comes into daily life.

The existing common sound insulation glass mainly comprises hollow glass, laminated composite glass and vacuum glass. The sound insulation effect of the hollow glass is relatively poor, the vacuum glass has a good sound insulation effect but is expensive, and the production process is not completely mature; compared with hollow glass and vacuum glass, the laminated composite glass is sound insulation glass with better cost performance. However, the laminated composite glass existing on the market often has poor sound insulation performance, and cannot exist in a form of partial structural bending, namely, broken line bending instead of smooth arc bending even if the partial structural bending is performed.

SUMMERY OF THE UTILITY MODEL

Not enough to the above-mentioned among the prior art, the utility model provides a glass of making an uproar falls in curved system with high transparency can effectively solve current glass sound insulation performance poor, and can not compromise the problem that the curved form of arc exists.

For solving the above technical problem, the utility model discloses a technical scheme does:

the bending noise reduction glass with high transparency comprises an arc-shaped part and a vertical part which are of an integrated structure; the arc part comprises at least two pieces of arc glass; the vertical part comprises at least two pieces of vertical glass; a communicated cavity is formed between the arc glass and the vertical glass; the cavity is filled with a noise reduction layer.

Further, the arc length of the arc-shaped part is 20-30 cm.

Further, the central angle of arc portion is 20 ~ 45.

Further, the central angle of the arc-shaped portion is 32 °.

Further, the arc length of the arc-shaped part is 22-27 cm.

Further, both the arc glass and the vertical glass are float glass having a thickness of 5 mm.

Further, the noise reduction layer is made of acrylic materials or methyl methacrylate materials.

The utility model has the advantages that:

1. this device is through setting up arc portion and the vertical part that is the integral type structure to arc portion and the vertical part intussuseption that have the cavity are filled with and are fallen the layer of making an uproar, and the transparency is high, and to the sound insulation volume of the sound wave that frequency is 125 ~ 400Hz has reached 24.7 ~ 38.8, to the sound wave that frequency is 500 ~ 2500Hz, the sound insulation volume can reach about 40, and to the sound wave that frequency is up to 3150 ~ 5000Hz, the sound insulation volume can reach about 49 the highest.

2. This device is provided with arc portion, make the sound wave when passing through this device, via arc portion, can form more reflections, thereby make the sound wave can obtain preliminary decay as far as possible, then the sound wave when arc portion and vertical part through this device, can with the layer friction of making an uproar falls in it, the layer of making an uproar also can prevent the conduction of sound wave of falling, thereby arouse absorption decay or viscous attenuation, the resistance acting is consequently need overcome to the sound wave, thereby make the sound wave energy weaken, in order to reach the purpose of making an uproar falls in shielding the sound wave.
