Example Embodiment

[0011] Such as figure 1 , 2 As shown, the sound-absorbing and insulating barrier panel of the present invention includes a panel 4 and a back panel 2. The panel 4 is provided with a plurality of perforations 5, and the panel 4 and the back panel 2 are arranged on the frame. A cavity 7 is formed between 2 and the cavity 7 is provided with a sound-absorbing material. The front panel 4 and the back panel 2 are fixed to the frame respectively to make the barrier panel have a strong resistance to external load, and the sound absorption material is arranged between the panel 4 and the back panel 2 to make the barrier panel have better sound absorption and sound insulation effects.

[0012] Both the face plate 4 and the back plate 2 are provided with concave and convex waves. A concave-convex wave pattern is pressed in the lateral direction of the face and back plate. The concave-convex wave pattern changes the refraction angle of part of the sound wave and increases the sound absorptio...

Abstract

The invention provides a sound-absorbing and insulating barrier board with a wide sound-absorbing frequency band and good sound-absorbing and insulating effects, which includes a panel and a backboard. Installed on the frame, a cavity is formed between the panel and the back plate, and sound-absorbing material is arranged in the cavity. The surface and the back panel are respectively fixed to the skeleton so that the barrier panel has a strong resistance to external force loads, and the sound-absorbing material is arranged between the panel and the back panel to make the barrier panel have better sound absorption and sound insulation effects.

Description

technical field [0001] The invention relates to a traffic sound insulation barrier device, in particular to a sound absorption and insulation barrier board. Background technique [0002] With the rapid development of highways, urban light rails, subways and other transportation facilities, it has brought great convenience to people's travel, but at the same time, traffic noise pollution has become increasingly serious. Most of the existing sound-absorbing and noise-reducing products are planar sound-absorbing components that have been punched and sprayed on the metal surface, and the perforation aperture is in the range of 2 to 2.5mm. , and there is often sound leakage at the connection between components and components, which reduces the noise reduction effect of the overall project. Contents of the invention [0003] The invention provides a sound-absorbing and insulating barrier board with a wide sound-absorbing frequency band and good sound-absorbing and insulating ef...
