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-friendlytype type sound absorption barrier.
Background technology
In prior art, in order to reach good noise reduction, the combination of materials of rotary glass acoustical cotton is filled out between the acoustic barrier many employings two metal sound insulation panel for road noise reduction process, gapless between metal sound insulation panel and sound absorption cotton, in this combination of materials, inside fill out rotary glass acoustical cotton poor to low frequency noise sound absorbing capabilities, easy generation human body stimulates in an assembling process simultaneously, and easily pile up, after making moist, sound absorbing capabilities declines.Therefore the combination of materials of traffic absorbent lined barrier need to improve, and metal sound insulation panel corrosion resistance is poor.
Summary of the invention
The object of this invention is to provide a kind of environment-friendlytype type sound absorption barrier.
For solving the problems of the technologies described above, technical scheme of the present invention is:
A kind of environment-friendlytype type sound absorption barrier, comprise box body, lid and absorbent treatment, described lid is movably connected on box body, and described absorbent treatment to be located in box body and and all to form cavity structure between box bottom and lid.
Above-mentioned pair of cavity structure, strengthens the frequency range of sound absorption reduction significantly, improves the actual effect of absorbent lined barrier.Absorbent treatment material therefor is preferably polyester fibre acoustic panel, overcomes poor, unstable, the heavy-polluted defect of acoustical cotton sound absorption qualities in prior art.
Above-mentioned box bottom refers to face relative with lid in cartridge inner surface.
In order to described lid easy to use is connected with 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 is also 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 to strengthen acoustically effective further, strengthen the structural strength of absorbent treatment, described wave bottom width is 15 ~ 40mm, and wave is high is 5 ~ 150mm; It is 10mm ~ 50mm that described absorbent treatment does not comprise the thick of wave.
Refer to the part between wave Origin And Destination at the bottom of above-mentioned wave, wave bottom width refers to the distance between wave Origin And Destination.
In order to strengthen the effect of noise reduction sound absorption further, described cavity is thick is 5 ~ 150mm.
While strengthening acoustically effective to make absorbent treatment, can also play support reinforcing effect, described cavity is thick equal with wave height.
In order to strengthen acoustically effective, described lid is perforated panel structure.
In order to strengthen acoustically effective further, the hole of described perforated panel is circular, and 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.
While ensureing acoustically effective, do not waste material, easy to use, the thick of described environment-friendlytype type sound absorption barrier is 50mm ~ 200mm.The width of absorbent lined barrier can make arbitrarily according to actual needs, and used width is 500 ~ 3000mm.
While strengthening acoustically effective, extend application life of absorbent lined barrier, it is the glass fibre reinforced plastic structure of 3 ~ 5mm that described box body and lid are thick, and absorbent treatment is polyester fiber plated construction.More firm in order to make box body and lid be connected, can establish again outward at box body and lid and strengthen structure.
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, can anti-theft, non-secondary pollution and have good corrosion resistance, extends the application life of surperficial acoustical board; Absorbent treatment adopts polyester fibre acoustic panel, water-fast, and after water logging, drainage is strong, and sound absorption qualities does not decline, and form is constant, simultaneously harmless, environmentally safe, odorlessness; Can integrated mould shaping, assemble easy to process, without the need to any metalwork; For the screen body that 100mm is thick, its NRC >=0.70.
