Abstract
The utility model relates to a high efficiency aluminum fiber acoustic barrier with multi cavity and double sides, which is used in city traffic roads and railway traffic to control traffic noises belonging to acoustic barrier industry technology domain. Aluminum honeycomb is set between the aluminum frames. Aluminum micro-perforated panel is on both side of the aluminum honeycomb and integrated with the aluminum honeycomb. Aluminum fiber embossing empty cavity plates are on both sides of the integrated body. The utility model is of simple, compact and reasonable structure. The high strength aluminum honeycomb is composed of many mutual restraint dense honeycombs like many small I-steel beams, which can disperse the directional pressure from the plate, so that the high smoothness of plate can maintained when the pressure strength is of large area and the plate is under uniform force. The utility model can absorb 80 percent of the traffic noise and reduce the pollution to surrounding environment. The utility model has long service life and can reduce traffic noise greatly without secondary pollution.
Description
Technical field
The utility model relates to the two-sided sound barrier of a kind of efficient aluminum fiber multi-cavity, specifically is used for urban traffic circuit and track traffic, controls traffic noise, belongs to sound barrier industry technology field.
Background technology
Before the utility model is made, in prior art, be used for urban traffic circuit and urban track traffic, the sound barrier that reaches traffic noise control normally adopts aluminium sheet punching or aluminium sheet louvered structure or foamed aluminium board combining structure.These three kinds of traffic noise control structures are all low to noise control effect, and especially the foamed aluminium board combining structure costs an arm and a leg, and is easily crisp; Therefore, long service life.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point, thereby provide a kind of aluminum fiber honeycomb multi-cavity abatvoix of two-sided sound-absorbing, can reduce the pollution of traffic noise to surrounding enviroment, long service life is installed in the two-sided sound barrier of efficient aluminum fiber multi-cavity that railway or city rail traffic route can significantly reduce traffic noise.
Main solution of the present utility model is achieved in that
The utility model mainly adopts aluminium honeycomb 3 to be arranged in the middle of the aluminium chassis 5, on aluminium honeycomb 3 two sides aluminium microperforated panel 4 is housed respectively and is combined into one, and on its combined integrated two sides aluminum fiber concave-convex cavity plate 1 is housed respectively.
Compared with the prior art the utility model has the following advantages:
The utility model is simple, compact and reasonable for structure; Because adopting high-intensity aluminium honeycomb is to be made of just as many little steel I-beams many dense cellular that pin down mutually, can disperse the directional pressure from face, makes the intensity of the stressed even assurance surface pressure of face still can keep very high planeness than large tracts of land the time; Because the high frequency traffic noise is generally at 250～2000Hz, the sound absorption mean coefficient of three octaves can absorb 80% of traffic noise greater than 0.8, can reduce the pollution of traffic noise to surrounding enviroment, long service life is installed in railway or city rail traffic route and can significantly reduces traffic noise; Fibrous material to nonmetal cotton classes such as synthetic cotton, rock wool, sponge, glass wool, natural cotton, mineral wools does not generally adopt, thereby can not produce secondary pollution.
Description of drawings
Fig. 1 is the cross-sectional structural representation of the utility model.
Fig. 2 is the utility model aluminium chassis structural representation.
The specific embodiment
Embodiment during following the utility model is incited somebody to action in conjunction with the accompanying drawings is further described:
The utility model mainly is made up of aluminum fiber concave-convex cavity plate 1, two-layer cavity 2, aluminium honeycomb 3, aluminium microperforated panel 4, aluminium chassis 5 etc.
The utility model adopts aluminium honeycomb 3 to be arranged in the middle of the four limit aluminium chassis 5, on aluminium honeycomb 3 two sides aluminium microperforated panel 4 being housed respectively is combined into one, on its combined integrated two sides aluminum fiber concave-convex cavity plate 1 is housed respectively, forms two-layer cavity 2 in aluminum fiber concave- convex cavity plate 1 and 4 of aluminium microperforated panels.
The utility model adopts aluminum fiber concave- convex cavity plate 1 and 4 combinations of aluminium microperforated panel to be primarily aimed at the HFS of traffic noise; Aluminium microperforated panel 4 is formed the low frequency part that is primarily aimed at traffic noise with aluminium honeycomb 3.Its two sides sound absorption is aluminum fiber concave-convex cavity plate 1, and the two sides sound-absorption coefficient is identical.
Claims (2)
1, the two-sided sound barrier of a kind of efficient aluminum fiber multi-cavity, it is characterized in that adopting aluminium honeycomb (3) to be arranged in the middle of the aluminium chassis (5), on aluminium honeycomb (3) two sides aluminium microperforated panel (4) is housed respectively and is combined into one, aluminum fiber concave-convex cavity plate (1) is housed respectively on its combined integrated two sides.
