The closed noise barrier plateTechnical field
The present invention relates to a kind of road and track traffic noise reducing apparatus, be specifically related to a kind of absorbent lined barrier board.
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, brought great convenience for our trip, but stays in simultaneously the impact that near these expressways and light rail resident is standing traffic noise being open to traffic of urban light rail.In order to improve the civic dwelling environment, various absorbent lined barrier boards have been installed by relevant department in the road both sides and around tramway.
Present absorbent lined barrier board operated by rotary motion panel and backboard, panel and backboard all adopt slabbed construction, have the hole that absorbs sound on panel, between panel, backboard, skeleton are set, and porous absorption material is set between skeleton.Yet along with panel, development trend that the backboard sheet metal thickness is more and more thinner, the intensity of absorbent lined barrier board also more and more causes designer's common concern.Solution to this problem be generally 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 objective of the invention is in order to overcome deficiency of the prior art, provide a kind of rational in infrastructure, intensity is large, saves material, and is lightweight, the absorbent lined barrier board that acoustically effective is good.
Technical scheme: closed noise barrier plate of the present invention comprises beam column and vertical steel post, and described beam column is supported and formed by horizontal steel post, roofing support, purlin, and described beam column is fixedly connected with described vertical steel post by longitudinal bracing; Be fixed with noise barrier and absorbent lined barrier between described vertical steel post.
Described noise barrier is comprised of aluminum alloy outer frame and doubling glass plate.
Described absorbent lined barrier is comprised of skeleton, backboard and panel, and this panel and backboard are aluminium sheet, and described skeleton is galvanized sheet.
Beneficial effect: the present invention compared with prior art, its remarkable advantage is: adopt steel work, rational in infrastructure, intensity is large, saves material, lightweight, in use, acoustically effective is relatively good.

The specific embodiment
As Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5 and shown in Figure 6, the present invention includes beam column 1 and vertical steel post 2, described beam column 1 supports 5 byhorizontal steel post 3, roofing support 4, purlin and forms, and described beam column 1 is fixedly connected with described vertical steel post 2 bylongitudinal bracing 6; Be fixed withnoise barrier 7 and absorbent linedbarrier 8 between described vertical steel post 2; Describednoise barrier 7 is comprised of aluminum alloyouter frame 12 anddoubling glass plate 13; Described absorbent linedbarrier 8 is comprised of skeleton 9,backboard 10 andpanel 11, and thispanel 11 andbackboard 10 are aluminium sheet, and described skeleton 9 is galvanized sheet.The present invention adopts steel work, and is rational in infrastructure, and intensity is large, saves material, and lightweight, in use, acoustically effective is relatively good.
