Abstract
The utility model relates to a full sound-absorbing sound screening board which comprises steel stand columns. A stand column top cap is arranged at the top of the steel stand column; a screening object sound-absorbing cap is arranged above the stand column top cap; frameworks are arranged among the steel stand columns in the transverse direction; and sound-absorbing boards are fixedly arranged among the frameworks. The full sound-absorbing sound screening board adopts a steel structure, has a reasonable structure, high strength, and light weight, saves materials, and has a better sound-absorbing effect in use.
Description
Technical field
The utility model relates to different kinds of roads and track traffic and high ferro noise reducing apparatus, is specifically related to a kind of gobo baffle.
Background technology
Along with the progress of society and the development in city, people's living standard constantly improves, and urban traffic has become the most closely-related problem with us.Building up of a large amount of expressways, being open to traffic of urban light rail and high-speed railway brings great convenience for our trip, but stays in the influence that near the resident of these expressways, light rail and high ferro is standing traffic noise simultaneously.In order to improve the civic dwelling environment, relevant department in the road both sides and light rail, high ferro etc. various absorbent lined barriers have been installed around along the line.
Present gobo baffle operated by rotary motion panel and backboard, panel and backboard all adopt slabbed construction, have the sound absorption hole on the panel, between panel, the backboard skeleton are set, and porous absorption material is set between skeleton.Yet along with the more and more thinner development trend of panel, backboard sheet metal thickness, the intensity of gobo baffle also more and more causes designer's common concern.Solution to this problem generally be density and the intensity that increases skeleton, but this can increase the consumption of material significantly, and the weight of shield plates also can increase much thereupon.
Summary of the invention
Goal of the invention: the purpose of this utility model is in order to overcome deficiency of the prior art, provide a kind of rational in infrastructure, intensity is big, saves material, and is in light weight, the gobo baffle that acoustically effective is good.
Technical scheme: full sound absorption sound barrier panel described in the utility model comprises steel post, at this steel post top the column overhead guard is installed, and screen body sound absorption cap is installed above this column overhead guard; Between described steel post is horizontal, be provided with skeleton, between this skeleton, fixedly mount acoustical board.
At described acoustical board both sides difference installation panel and backboard, described panel is an aluminium sheet, and described backboard is a galvanized sheet.
Beneficial effect: the utility model compared with prior art, its remarkable advantage is: adopt steel work, rational in infrastructure, intensity is big, saves material, in light weight, in use, acoustically effective is relatively good.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is the structural representation of acoustical board.
The specific embodiment
As Fig. 1, Fig. 2 and shown in Figure 3, the utility model comprises steel post 1, at this steel post 1 top column overhead guard 2 is installed, and screen body sound absorption cap 3 is installed above this column overhead guard 2; Be provided with skeleton 4, fixed installation acoustical board 5 between this skeleton 4 at described steel post 1 between laterally; At described acoustical board 5 both sides difference installation panel 6 and backboard 7, described panel 6 is an aluminium sheet, and described backboard 7 is a galvanized sheet.The utility model adopts steel work, and rational in infrastructure, intensity is big, saves material, and in light weight, in use, acoustically effective is relatively good.
