Problems solved by technology

Since most sound-absorbing panels are placed in the open air, in rainy and snowy weather, rain and snow will flow into the interior of the sound-absorbing panel, erode the sound-absorbing panel, accelerate aging, and reduce the service life of the sound-absorbing panel

Embodiment Construction

[0015] As shown in the figure, the high-strength cement sound-absorbing board, the high-strength cement sound-absorbing board includes a sound-absorbing layer 1 and a sound-insulating layer 2, and a cavity is provided between the sound-absorbing layer 1 and the sound-insulating layer 2, and the sound-absorbing material is filled in the cavity 3. The surface of the sound-absorbing layer 1 is provided with a number of louver-type sound-absorbing holes 4 communicating with the cavity.

[0016] The inclination of the louver-type sound-absorbing hole 4 window can prevent dust, rain and snow from entering the interior of the sound-absorbing panel, so that the sound-absorbing material is not eroded by rain and snow; the surface of the sound-absorbing panel has a hydrophobic effect, which can effectively solve the freeze-thaw effect. Accelerated aging caused by moisture and cold can prevent damage to the sound-absorbing panels, and at the same time prevent weathering; the overall struc...

Abstract

The invention relates to a high-strength cement sound-absorbing plate, which comprises a sound-absorbing layer and a sound-insulating layer, wherein a cavity is formed between the sound-absorbing layer and the sound-insulating layer; sound-absorbing materials are filled into the cavity; the surface of the sound-absorbing layer is provided with a plurality of shutter-type sound-absorbing holes communicated with the cavity. The gradient of a shutter-type sound-absorbing hole window is set in such a manner that dust, rain and snow can be prevented from entering the inside of the sound-absorbing plate, and the sound-absorbing material is prevented from being corroded by rain and snow; the surface of the sound-absorbing plate has a hydrophobic effect, so that the problem of accelerated aging caused by freezing and thawing effects can be solved effectively, damages of moisture and cold to the sound-absorbing plate are prevented, and meanwhile weathering can be prevented; the high-strength cement sound-absorbing plate is molded at a time via a mold, and a unit plate has high structural stability and high structural strength; perlite and the like are taken as sound-absorbing materials, so that the structural strength of the sound-absorbing plate is enhanced while the sound-absorbing effect is ensured.

Description

Technical field: [0001] The patent of the present invention relates to a sound-absorbing device, in particular to a high-strength cement sound-absorbing board with long service life and high structural strength. Background technique: [0002] Sound-absorbing panels are mainly used to reduce noise pollution in transportation facilities such as highways, elevated roads, urban light rails, and railways. It is mainly composed of a main frame structure and a sound insulation panel. , Sound-absorbing components. Since most sound-absorbing panels are placed in the open air, in rainy and snowy weather, rain and snow will flow into the interior of the sound-absorbing panel, erode the sound-absorbing panel, accelerate aging, and reduce the service life of the sound-absorbing panel. Invention content: [0003] The purpose of the patent of the present invention is to provide a high-strength cement sound-absorbing board with long service life and high structural strength. [0004] In...
