Abstract
The invention discloses an environment-friendly type sound absorption barrier. The environment-friendly type absorbent sound barrier comprises a box, a box cover and a sound absorption layer, wherein the box cover is movably connected on the box, the sound absorption layer is arranged in the box, and a cavity is formed by the sound absorption layer, the bottom of the box and the box cover. By the aid of the cavity, frequency range for sound absorption and noise reduction is obviously enlarged, and practical effect of the sound absorption barrier is improved. The environment-friendly type sound absorption barrier is good in sound absorption effect, high in strength and stable in structure, and the cavity is flexible and controllable in size.
Description
Technical field
The present invention relates to a kind of environment-friendly type absorbent lined barrier.
Background technology
In the prior art, in order to reach preferably noise reduction, the sound barrier that is used for the road noise reduction process combinations of materials of filling out the rotary glass acoustical cotton between two metals sound insulation panel that adopt more, gapless between metal sound insulation panel and sound absorption cotton, in this combination of materials, in to fill out the rotary glass acoustical cotton relatively poor to the low frequency noise sound absorbing capabilities, easily human body being produced in assembling process simultaneously stimulates, and easily pile up, the rear sound absorbing capabilities that makes moist descends.Therefore the combination of materials of traffic absorbent lined barrier is still waiting to improve, and metal sound insulation panel corrosion resistance is relatively poor.
Summary of the invention
The purpose of this invention is to provide a kind of environment-friendly type absorbent lined barrier.
For solving the problems of the technologies described above, technical scheme of the present invention is:
A kind of environment-friendly type absorbent lined barrier comprises box body, lid and absorbent treatment, and described lid is movably connected on the box body, described absorbent treatment be located in the box body and and box bottom and lid between all form cavity structure.
Above-mentioned pair of cavity structure strengthened the frequency range of sound absorption reduction significantly, improved the actual effect of absorbent lined barrier.The sound absorbing layer material therefor is preferably polyester fibre acoustic panel, has overcome poor, unstable, the heavy-polluted defective of acoustical cotton sound absorption qualities in the prior art.
Above-mentioned box bottom refers to face relative with lid in the cartridge inner surface.
For described lid easy to use is connected with the box body draw-in groove.
In order to strengthen acoustically effective, described absorbent treatment is two-sided wave structure.The derivation of rainwater and fog also is convenient in the design of the structure of wave.
In order to strengthen the structural strength of absorbent treatment, the wave on described absorbent treatment two sides is orthogonal.
In order further to strengthen acoustically effective, strengthen the structural strength of absorbent treatment, described wave bottom width is 15～40mm, wave is high to be 5～150mm; Described absorbent treatment does not comprise the thick 10mm～50mm of being of wave.
Refer to the part between the wave Origin And Destination at the bottom of the above-mentioned wave, the wave bottom width refers to the distance between the wave Origin And Destination.
In order further to strengthen the effect of noise reduction sound absorption, described cavity is thick to be 5～150mm.
When making absorbent treatment strengthen acoustically effective, can also play the support reinforcing effect, described cavity is thick to be equated with the wave height.
In order to strengthen acoustically effective, described lid is the perforated panel structure.
In order further to strengthen acoustically effective, the hole of described perforated panel is circular, and the aperture is 2～6mm, perforated percentage 15～30%.Above-mentioned perforated percentage refers to that porose area sum accounts for the percentage of the panel gross area.
When guaranteeing acoustically effective, do not waste material, the convenient use, the thick of described environment-friendly type absorbent lined barrier is 50mm～200mm.The width of absorbent lined barrier can be made arbitrarily according to actual needs, and used width is 500～3000mm.
When strengthening acoustically effective, prolong the application life of absorbent lined barrier, described box body and lid are the glass fibre reinforced plastic structure of the thick 3～5mm of being, and sound absorbing layer is the polyester fiber plated construction.More firm for box body will be connected with lid, can outside box body and lid, establish again a little reinforcement structures.
Absorbent lined barrier of the present invention also can be used to build noise barrier.
Absorbent lined barrier acoustically effective of the present invention is good, and intensity is large, and Stability Analysis of Structures is pollution-free; The size of cavity has flexibility and controllability; The use of glass fibre reinforced plastic structure, but anti-theft, non-secondary pollution and have good corrosion resistance have prolonged the application life of surperficial acoustical board; Absorbent treatment adopts polyester fibre acoustic panel, and water-fast, drainage is strong after the water logging, and sound absorption qualities does not descend, and form is constant, and is simultaneously harmless, environmentally safe, odorlessness; But the integrated mould moulding is assembled easy to processly, need not any metalwork; For the thick screen body of 100mm, its NRC 〉=0.70.
