Abstract
The utility model relates to a sound-absorbing-insulating traffic screen panel, which is composed of a panel and a back panel, wherein, a plurality of projection parts are arranged on the panel which is provided with a plurality of through holes with at least two different hole diameters. Fillers are arranged in inner cavities of the projection parts of the panel. The inner side of the panel is provided with a metal sheet on which a plurality of through holes are arranged. The inner side of the back panel is provided with a honeycomb panel. A hollow body is arranged between the metal sheet and the honeycomb panel. Both ends of the panel and the back panel are connected by steel planets. The utility model adopts the panel provided with the projection parts, the metal sheet at the inner side and the through holes with the different hole diameters, which not only increases sound absorption areas but also plays the role of twice sound absorption. Simultaneously, the honeycomb panel is arranged on the inner side of the back plate, which can absorb noise energy again with the double functions of sound absorption and sound insulation. In addition, the fillers of sound absorption are arranged on the inner side of the panel, which lowers the influence of the noise.
Description
Technical field
The utility model relates to the sound absorption and insulation device, especially a kind of sound absorption and insulation traffic barrier plate.
Background technology
In the prior art, generally utilize sound absorption and insulation traffic barrier plate to reduce the influence that traffic noise brings for highway both sides resident living.Existing sound insulation traffic barrier plate is by beating with a kind of hole of aperture on the surface course metal sheet or open the purpose that the blinds hole reaches sound absorption, but its acoustically effective is poor; Simultaneously, do not dispose further sound absorption material or device on the backboard, make anti-acoustic capability not reach desired effects.
Summary of the invention
Technical problem of the prior art to be solved in the utility model is: because sound insulation traffic barrier plate of the prior art is by beating with a kind of hole of aperture on the surface course metal sheet or opening the purpose that the blinds hole reaches sound absorption, so acoustically effective is poor; Simultaneously, do not dispose further sound absorption material or device on the backboard, make anti-acoustic capability not reach desired effects.
The utility model is that the technical scheme that solution above-mentioned technical problem of the prior art is adopted provides a kind of sound absorption and insulation traffic barrier plate, described this sound absorption and insulation traffic barrier plate is made of panel and backboard, wherein, described panel is provided with a plurality of bossings, described panel is provided with a plurality of perforation, and include the perforation in two kinds of apertures in described a plurality of perforation at least, in the inner chamber that the bossing of described panel forms, the sound absorption filler is set, inboard at described panel is provided with metal sheet roof covering, described metal sheet roof covering is provided with a plurality of perforation, inboard at described backboard is provided with cellular board, be cavity between described metal sheet roof covering and the described cellular board, described panel is connected by steel plate at its two ends with backboard.Concrete, described panel and backboard constitute by metal sheet, and further, described backboard is provided with the cross section and is trapezoidal a plurality of continuous protuberance.
Further, described sound absorption filler is made of centrifugally glass-wool, and described centrifugally glass-wool is by the PVF film wrapped.
Further, the cross sectional shape of described bossing is a triangle.Further, the cross sectional shape of described bossing also can adopt trapezoidal.And further, in described a plurality of bossings, having the cross sectional shape of a bossing at least is triangle, and to have the cross sectional shape of a bossing at least be trapezoidal.
