Abstract
The invention relates to a sound barrier board for high-speed rails. The sound barrier board comprises a frame consisting of a plurality of steel upright posts and a base plate; an acoustic board is fixedly arranged in the frame; one side of the acoustic board is provided with a fixing plate; the acoustic board is tightly connected with the fixing plate by a bolt structure; and both sides of the acoustic board are provided with single-tube rubber pads. The sound barrier board is of steel structure, so that the structure is reasonable, the strength is high, the material is saved, the weight is light, and the sound absorption effect is good in use.
Description
Technical field
The present invention relates to different kinds of roads and track traffic and high ferro noise reducing apparatus, be specifically related to a kind of gobo baffle.
Background technology
Along with the progress and the development of city of society, 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 objective of the invention 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: high ferro sound barrier panel of the present invention comprises the framework that steel post and base plate are formed; In this framework, fixedly mount acoustical board; Be provided with fixed head in said acoustical board one side; Said acoustical board closely is connected with said fixed head through bolt arrangement, in said acoustical board both sides the single tube rubber pad is installed.
Difference installation panel and backboard in said acoustical board both sides; Said panel is an aluminium sheet, and said backboard is an aluminium sheet.
Beneficial effect: the present invention 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 invention;
Fig. 2 is the side-looking enlarged drawing of Fig. 1;
Fig. 3 is the structural representation of acoustical board.
The specific embodiment
Like Fig. 1, Fig. 2 and shown in Figure 3; The present invention includes the framework 3 that steel post 1 and base plate 2 are formed; Fixed installation acoustical board 4 in this framework 3; Be provided with fixed head 5 in said acoustical board 4 one sides, said acoustical board 4 closely is connected with said fixed head 5 through bolt arrangement 6, in said acoustical board 4 both sides single tube rubber pad 7 is installed; Difference installation panel 8 and backboard 9 in said acoustical board 4 both sides; Said panel 8 is an aluminium sheet, and said backboard 9 is an aluminium sheet.The present invention adopts steel work, and is rational in infrastructure, and intensity is big, saves material, and in light weight, in use, acoustically effective is relatively good.
