The whole barrier plate is rectangular, and comprises a front panel and a back panel which are made of metal plates, the front panel is provided with a plurality of sound through holes, and folded edges are arranged at the long edges of each of the front panel and the back panel, wherein flanges with the same section contour are arranged on the upper folded edges of the front panel and the back panel, grooves with the same section contour are formed on the lower folded edges of the front panel and the back panel, the section contours of the flanges and the grooves are also the same, and the front panel and the back panel are tabled together through the upper and lower folded edges to form a cavity in the inner part; and a sound absorption layer and a sound insulation layer are arranged in the cavity, the sound insulation layer is one or more layers of cement boards tightly attached to the back panel, and the sound absorption layer is tightly attached to the front panel and made of a sound absorption material. The barrier plate is simple in structure and convenient to install, and has a good sound absorption and insulation effect.
Description
Technical field
The utility model belongs to sound-absorbing acoustic isolation facility technical field, relates in particular to a kind of railway and uses the acoustic screen baffle.
Background technology
Along with the development of high-speed railway, urban track traffic such as speedway, viaduct etc. are the daily life of affect people's muchly.Noise along the line has caused the appearance of serious harm, particularly high ferro more to aggravate this problem to the healthy of people.Therefore,, noise barrier is set has become necessary selection through the intensive highway section of personnel such as residential block, commercial area at city rail.The general structure more complicated of noise barrier of the prior art is installed also cumbersomely, and the sound-absorbing soundproof effect is relatively poor.
The utility model content
The utility model provides a kind of simple in structure, installation is convenient, the sound-absorbing soundproof effect is good railway acoustic screen baffle for solving the technical problem that exists in the known technology.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is: railway noise barrier slab integral is rectangular; Comprise front panel and the backplate processed by metal sheet; On said front panel, be provided with a plurality of penetrable sound holes; Be equipped with flanging on the long limit of said front panel and backplate, wherein the flanging on both tops is provided with the identical flange of cross section profile, and the flanging of both bottoms is provided with the identical groove of cross section profile; The cross section profile of said flange and groove is also identical, and said front panel and backplate are entrenched togather through last lower hem and form cavity in inside; In said cavity, be provided with sound absorbing layer and puigging, said puigging is one or more layers cement board of being close to said backplate, and said sound absorbing layer is close to said front panel.
The utility model can also adopt following technical scheme:
Said sound absorbing layer is chosen for one or more in layer of mineral wool, glass fibre cotton layer, spongy layer or the rock wool layer.
The cross section profile of said flange and groove is an isosceles trapezoid.
Also comprise the side plate that is located at two ends, said side plate is riveted on the edge of said front panel and backplate.
Advantage and the good effect that the utlity model has are: owing to adopted above-mentioned design, the utility model is simple in structure.Have the design of the front panel and the backplate of flanging, it is chimeric mutually to make both pass through preset flange and groove, has saved the step that both are fixed together, and has promoted the convenience of producing and installing.Simultaneously; The cross section profile of flange and groove is identical, and this just makes whole acoustic screen baffle become the unit of a standard, can select suitable quantity to pile up connection according to the needs of reality; Be aided with simple fastening devices again and get final product, this has further promoted the convenience of installing.The setting of sound absorbing layer and puigging is stopped noise once more in the cavity after obtaining strong absorption, and whole sound-absorbing soundproof effect is good.

Fig. 1 is the front view of the utility model;
Fig. 2 is the sectional view of the utility model.
Among the figure: 1, flange; 2, front panel; 3, penetrable sound hole; 4, sound absorbing layer; 5, backplate; 6, puigging; 7, groove.
The specific embodiment
For further understanding summary of the invention, characteristics and the effect of the utility model, the following examples of giving an example now, and conjunction with figs. specifies as follows:
See also Fig. 1 and Fig. 2, the railway acoustic screen baffle of the utility model is designed to standardized installation unit, and its whole one-tenth rectangle is designed to different length and width according to actual needs.Comprise the front panel 2 and backplate 5 processed by metal sheet, plate 2 is provided with a plurality of penetrable sound holes 3 in front, lets noise therefrom pass the inner chamber that gets into shield plates.Be equipped with flanging on the long limit of front panel 2 and backplate 5; Wherein the flanging on both tops is provided with the identical flange of cross section profile 1; The flanging of both bottoms is provided with the identical groove of cross section profile 7, and the cross section profile of flange 1 and groove 7 is also identical, all is arranged to isosceles trapezoid.Front panel 2 is entrenched togather through last lower hem with backplate 5, forms cavity in inside.
In cavity, be provided with sound absorbing layer 4 and puigging 6, wherein puigging 6 is for to be close to one or more layers cement board on the backplate 5, and sound absorbing layer 4 is close on the front panel, is processed by damping material.In order to reach better sound-absorbing effect, said sound absorbing layer is chosen for one or more in layer of mineral wool, glass fibre cotton layer, spongy layer or the rock wool layer.
In the present embodiment, also comprise the side plate that is located at two ends, this side plate is riveted on the edge of front panel 2 and backplate 5, in order to the acoustic screen baffle is encapsulated as an integral body.
During installation, be elementary cell with above-mentioned noise barrier plate, according to height, the length of design barrier, select the unit of suitable quantity to pile up connection, promptly the flange 1 of next unit embeds in the groove of a last unit, fastening devices is set again fixes and get final product.
More than the embodiment of the utility model is specified, but said content is merely the preferred embodiment of the utility model, can not be considered to be used to limit the practical range of the utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the utility model.
