Abstract
The invention discloses a sound barrier, and provides a sound barrier which is good in noise-reducing effect and lower in cost. The technical scheme adopted by the invention is as follows: the sound barrier comprises a sound barrier shell, a panel and a sound absorbing board, wherein pits are uniformly distributed on the panel of the sound barrier; holes are arranged on the pits or the panel outside the pits; the sound absorbing board in the shell is made of glass fiber cotton; a glass fiber cloth is arranged between the glass fiber cotton and the panel; and a groove is arranged at the rear side surface of the sound barrier shell. The sound barrier disclosed by the invention is used for insulating sounds and reducing noises.
Description
Technical field:
The present invention relates to a kind of device that reduces noise, particularly a kind of sound barrier.
Background technology:
At present mostly the sound barrier that is provided with in the both sides of speedway, railway, high ferro or subway is that glass epoxy makes panel, the hole is set on the panel, the built-in polystyrene foamed material of panel is made sound absorption material, this structure is lower with respect to the price of in the past baffle, but the effect of noise reduction is still undesirable.
Summary of the invention:
The object of the invention provides a kind of excellent noise reduction effect and the lower a kind of sound barrier of price.Realize that technical scheme of the present invention is, a kind of sound barrier, comprise sound barrier housing, panel and acoustical board, it is characterized in that: be evenly equipped with pit on the sound barrier panel, be provided with the hole with the outer panel of pit on the pit, acoustical board in the housing is a glass fibre cotton, is provided with glass fabric between this glass fibre cotton and described panel.A kind of sound barrier is characterized in that: the trailing flank of sound barrier housing is provided with groove.The present invention has excellent noise reduction effect and the low advantage of price compared with the prior art.
Description of drawings:
Fig. 1 is a front view of the present invention, and Fig. 2 is the A-A sectional view of Fig. 1.
The specific embodiment:
With the following Examples the present invention is elaborated, the relatively poor reason of noise reduction of existing sound barrier mainly contains the reason of two aspects, the one, the sound barrier panel is the plane, the 2nd, built-in polystyrene foam is made sound absorption material, its acoustically effective is undesirable, for this reason, the present invention adopts glass fibre cotton to make sound absorption material.Sound barrier panel 1 is made uniform square pit 2, make panel become concavo-convex surface, this surface has the effect that reflects noise reduction to sound wave, be provided with on the pit bottom surface of sound barrier panel on the panel outside hole 4 and the pit and be provided with hole 3, and the acoustically effective of glass fibre cotton 8 is far above cystosepiment.The preparation method of above-mentioned sound barrier is, glass fibre cotton is filled in the groove of sound-screen housing, after pasting gluing glass fabric 6 in its surface then, be placed on the sound barrier panel on this glass fabric again after, with rivet sound barrier housing and panel are fixed into integral body.The trapezoidal groove 9 that the upper surface of sound barrier housing is provided with trapezoidal convex body 5 and lower surface matches, and this structure is convenient to the scene and is assembled.A groove 7 is set on the trailing flank of sound barrier housing, is used for strengthening its rigidity.
The present invention after tested, its sound absorption coefficient height can reach 0.75-0.95, sound insulation factor can reach 32-33.6dB.
Claims (2)
1. sound barrier, comprise sound barrier housing, panel and acoustical board, it is characterized in that: be evenly equipped with pit on the sound barrier panel, be provided with the hole with the outer panel of pit on the pit, acoustical board in the housing is a glass fibre cotton, is provided with glass fabric between this glass fibre cotton and described panel.
2. a kind of sound barrier as claimed in claim 1 is characterized in that: the trailing flank of sound barrier housing is provided with groove.
