Abstract
The utility model provides a multi-layer micro-porous silence ventilation plate made of a composite plate, characterized in that the upper side or the lower side of the composite material plate is uniformly provided with columnar small holes and columnar big holes. The bottoms of the big holes are in a conical shape, and the small columnar holes and the big columnar holes are in coaxial lines. The top surfaces of small hole pillars and the bottom surfaces of the bog hole pillars are on the same horizontal plane. The plate can be used solely, or in a plurality of the plates can be used in overlapping.
Description
One, technical field
The utility model belongs to a kind of multi-layer microporous noise reduction air permeable plate, and the sheet material of this structure can be that sound insulation can ventilate again, reaches the ventilative effect of noise reduction.
Two, background technology
Present various noise reduction sheet material has reached erasure effect preferably, yet but can not use as the air ventilation material basically, that is to say that the material gas permeability of noise reduction is poor, and ventilative material soundproof effect is also very poor.But because social industrialization constantly develops rapidly, abate the noise and pollute and ventilation becomes a kind of contradictory phenomena, as the residential block, urban in order to stop traffic and industrial noise, the door and window of often can only being kept in detention, like this, when stopping noise, fresh air is also refused outdoors thereupon.
Three, summary of the invention
The purpose of this utility model is can reduce noise effectively with composite board design is a kind of, the used multi-layer microporous noise reduction air permeable plate of architectural decoration that again can ventilation.
The technical solution of the utility model realizes in the following manner:
The utility model is processed by composite board, it is characterized in that on composite panel or below evenly be provided with cylindrical aperture, below composite panel or above evenly be provided with cylindrical macropore, the macropore bottom is tapered, two hole coaxial lines, aperture is enclosed within the macropore, and the beginning face of its Kong Zhu and the bottom surface of macropore post are on a horizontal plane; This plate can use by monolithic, also can use by several superpositions;
Be provided with pore between cylindrical macropore and the cylindrical macropore, increase the energy consumption of sound wave.
The inner surface of cylindrical macropore is made as non-smooth coarse shape, penetrates area in order to the reflexed that enlarges sound wave, consumes the echo of sound wave.
Compared with the prior art the utility model is characterized in that this plate has the three dimensional network cavernous structure, can sound-absorbing, noise reduction, and dustproof, be convenient to clean characteristics simple in structure, easy to use.
Four, description of drawings
Fig. 1-of the present utility model flat to sectional drawing;
Fig. 2-longitudinal sectional drawing of the present utility model;
The schematic perspective view of cylindrical macropore and cylindrical aperture during Fig. 3-the utility model two plate superpositions.
The cylindrical aperture 4-of the cylindrical macropore 3-of 1-composite panel 2-pore
Five, embodiment
For further disclosing the technical solution of the utility model, be described in detail by embodiment below in conjunction with Figure of description:
The utility model is processed by composite panel 1, it is characterized in that on composite panel 1 or below evenly be provided with cylindrical aperture 3, below composite panel 1 or above evenly be provided with cylindrical macropore 2, macropore 2 bottoms are tapered, two hole coaxial lines, the beginning face of aperture 3 and the bottom surface of macropore 2 are on a horizontal plane; Be provided with pore 4 between macropore and the macropore; This plate can use by monolithic, and the foraminate one side of this plate is outside, and another side is adherent, also can use by two superpositions, and macropore is relative, and the aperture adherent one side of one side outside or aperture is outside.
Claims (3)
1, a kind of multi-layer microporous noise reduction air permeable plate, process by composite board, it is characterized in that on composite panel or below evenly be provided with cylindrical aperture, below composite panel or above evenly be provided with cylindrical macropore, the macropore bottom is tapered, small cylindrical hole and great circle cylindrical hole coaxial line, the beginning face of small bore columns and the bottom surface of macropore post are on a horizontal plane; This plate can use by monolithic, also can use by several superpositions.
