Problems solved by technology

[0006] Therefore, the present invention provides a vertical metal sound barrier unit panel to overcome the structure of the perforated panel in the prior art, which is prone to water seepage points to the sound-absorbing module in rainy and snowy weather, resulting in increased cotton bulk density, increased load, and mildew. Aging affects the sound absorption effect and the lack of life

Embodiment Construction

[0026] see in conjunction Figure 1 to Figure 6 As shown, according to an embodiment of the present invention, an upright metal sound barrier unit panel is provided, including a sound absorption module 21, and the side of the sound absorption module 21 facing the sound source is provided with a perforated panel 22, and the sound absorption module 21 is provided with a back plate 23 on the side away from the sound source, the perforated panel 22 and the back plate 23 are assembled and connected as a whole, and together form a package around the outer peripheral side of the sound-absorbing module 21, the perforated The panel 22 has a first perforated plate 221 and a second perforated plate 222. The first perforated plate 221 is located above the second perforated plate 222. From top to bottom along the height direction, the first perforated plate 221 gradually Away from the sound-absorbing module 21, the second perforated plate 222 gradually approaches the sound-absorbing module...

Abstract

The invention provides a vertical metal sound barrier unit plate which comprises a sound absorption module, a perforated panel is arranged on the side, facing a sound source, of the sound absorption module, the perforated panel is provided with a first perforated plate and a second perforated plate, the first perforated plate is located above the second perforated plate, and the second perforated plate is located above the first perforated plate from top to bottom in the height direction. The first perforated plate is gradually far away from the sound absorption module, the second perforated plate is gradually close to the sound absorption module, the lower end of the first perforated plate is connected with the second perforated plate, and a rain cover is arranged on the outer side of an orifice of a first hole formed in the first perforated plate. According to the vertical metal sound barrier unit plate, cotton volume weight increase, load increase and mildew aging caused by water seepage of the sound absorption module can be avoided, the sound absorption effect is improved, and the service life is prolonged.

Description

technical field [0001] The invention belongs to the technical field of noise reduction barrier design, and in particular relates to an upright metal sound barrier unit plate. Background technique [0002] With the continuous progress and development of my country's transportation industry, the construction mileage of high-speed rail, rail transit, municipal roads, expressways and other transportation has increased at a substantial rate to meet people's travel, goods exchanges and information exchanges. my country has gradually become a wheel with countries on track. Cars running on the road and trains on the tracks will generate relatively strong traffic noise when passing through cities, suburbs and villages. There are also various types of noise, including wheel-rail noise, aerodynamic noise, tire friction noise, squeal Flute noise, etc., and as the speed continues to increase, the intensity of the noise, the degree of exceeding the standard and the degree of harm are also...
