Abstract

The invention belongs to the technical field of sound-absorbing boards and discloses a double-layer sound-absorbing board for subways. The double-layer sound-absorbing board is composed of a base material layer and sound attenuation holes, and is characterized in that the base material layer of the oriented strand wood chip sound-absorbing board is an oriented strand board, one side of the base material forms a sound-absorbing board surface, the other side of the base material layer forms a sound-absorbing board bottom surface, sound attenuation grooves are arranged in the sound-absorbing board surface, the sound attenuation holes in interval distribution penetrate the bottom surfaces of the sound attenuation grooves, or the sound-absorbing board surface is communicated with the sound-absorbing board bottom surface, a veneering layer is arranged at the upper end of the sound-absorbing board surface, a sound attenuation bottom layer is arranged on the sound-absorbing board bottom surface, and the corresponding side edges of the base material layer are provided with connecting flanges and connecting grooves. The oriented strand board is adopted as the base material, more sound is absorbed, the structure is simple, and the double-layer sound-absorbing board has good sound attenuation and absorption effect and high strength and dimensional stability.

Description

Subway dual layer acoustical plate
Technical field
The present invention relates to abatvoix technical field, particularly relates to a kind of subway dual layer acoustical plate.
Background technology
Europe deals used in the market is mainly used in Furniture manufacture, building materials, ornament materials and packing.Europe deals is with small dimension wood and reel etc. for raw material, through flaking, de-oiling, drying, applying glue, to mat formation and hot-forming, has higher intensity and dimensional stability.And traditional abatvoix adopts soft sound absorption materials to make usually, though sound-absorbing, not easily moulding, intensity is low, and kind is single.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, proposing a kind of subway dual layer acoustical plate.
Scheme of the invention of the present invention is: subway dual layer acoustical plate, be made up of substrate layer and bloop, the substrate layer of described abatvoix is Europe deals, substrate layer one side forms abatvoix face, substrate layer another side forms abatvoix bottom surface, abatvoix face is provided with noise reduction groove, bloop spaced apart runs through noise reduction groove floor, or abatvoix face communicates with abatvoix bottom surface, upper end, abatvoix face is provided with overlay coating, abatvoix bottom surface is provided with noise reduction bottom, and the side that substrate layer is corresponding is provided with and connects chimb and connecting groove.
Preferably, described substrate layer comprises the lamella of two superpositions.
Advantage of the present invention adopts Europe deals to make base material, increases sound-absorbing simple structure, make it not only have good noise reduction sound-absorbing effect, and have higher intensity and dimensional stability, and have the beautification function of trim board simultaneously.Make sound-absorbing cost of installation reduce by 40%, one plate multiplex, result of use is good.
Detailed description of the invention
For making the technical problem to be solved in the present invention, technical scheme and advantage clearly, be described in detail below in conjunction with specific embodiment.
Subway dual layer acoustical plate of the present invention, be made up of substrate layer and bloop, the substrate layer of described abatvoix is Europe deals, and substrate layer one side forms abatvoix face, and substrate layer another side forms abatvoix bottom surface, abatvoix face is provided with noise reduction groove, bloop spaced apart runs through noise reduction groove floor, or abatvoix face communicates with abatvoix bottom surface, and upper end, abatvoix face is provided with overlay coating, abatvoix bottom surface is provided with noise reduction bottom, and the side that substrate layer is corresponding is provided with and connects chimb and connecting groove.
Preferably, described substrate layer comprises the lamella of two superpositions.
Advantage of the present invention adopts Europe deals to make base material, increases sound-absorbing simple structure, make it not only have good noise reduction sound-absorbing effect, and have higher intensity and dimensional stability, and have the beautification function of trim board simultaneously.Make sound-absorbing cost of installation reduce by 40%, one plate multiplex, result of use is good.
The above is the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the prerequisite not departing from principle of the present invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.

Claims (2)
