Description
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.
Drawings
FIG. 1 is a schematic structural view of the apparatus;
fig. 2 is a side view of the device.
Wherein, 1, an arc part; 2. a vertical portion; 3. a noise reduction layer; 4. arc-shaped glass; 5. perpendicular to the glass.
Detailed Description
The following description of the embodiments of the present invention is provided to facilitate the understanding of the present invention by those skilled in the art, but it should be understood that the present invention is not limited to the scope of the embodiments, and various changes may be made apparent to those skilled in the art within the spirit and scope of the present invention as defined and defined by the appended claims.
As shown in fig. 1 and 2, the bending noise reduction glass with high transparency comprises an arc-shaped part 1 and a vertical part 2 which are of an integral structure, and in addition, reinforcing ribs (not shown in the drawings) for protecting and reinforcing the arc-shaped part 1 and the vertical part 2 can be arranged at the joint of the arc-shaped part 1 and the vertical part 2 according to needs.
As shown in fig. 2, the arc part 1 is composed of two arc glasses 4 having a thickness of 5mm, and a cavity is formed between the two arc glasses 4. The central angle of the arc-shaped part 1 is 20-45 degrees, preferably 32 degrees, and the arc length is preferably 22-27 cm.
As shown in fig. 2, the vertical part 2 is also composed of two vertical glasses 5 having a thickness of 5mm, and the cavity formed by the two vertical glasses 5 is communicated with the cavity of the arc part 1. Preferably, both the curved glass 4 and the vertical glass 5 are float glass.
As shown in fig. 2, the noise reduction layer 3 made of an acrylic material or a methyl methacrylate material is filled in the cavity.
And (3) detecting the noise reduction performance: the glass prepared by the method is subjected to noise reduction performance detection by referring to GB/T8485 and 2008. The results are shown in Table 1.
