Abstract
The utility model relates to a color steel sandwich sound screen comprising steel upright posts, wherein color steel sandwich plates are arranged between the steel upright posts and are in compressing connection with the steel upright posts through Z-shaped spring buckles; each color steel sandwich plate comprises a color steel face plate, sandwich plates and a galvanized back plate; and the upper and the lower connecting parts of the color steel face plates and the galvanized back plate adopt embedded type concave-convex groove structures. The color steel sandwich sound screen has the advantages of reasonable structure, large strength, material conservation, light weight and good sound absorption effect.
Description
Technical field
The utility model relates to different kinds of roads and track traffic and high ferro denoising device, is 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 purpose of the utility model is to overcome the deficiency of above-mentioned prior art, provide a kind of rational in infrastructure, intensity is big, saves material, and is in light weight, the Felt that defening effect is good.
Technical scheme: in order to solve the problems of the technologies described above, the described color steel sandwich sound barrier of the utility model, it comprises steel post, between this steel post, all is provided with chromatic steel sandwich plate, this chromatic steel sandwich plate compresses with said steel post through Z type spring fastener and is connected; Said steel sandwich board comprises color steel panel, sandwiched plate and zinc-plated backboard, and said color steel panel and zinc-plated backboard coupling part up and down are embedding formula tongue and groove structures, and this structure has strengthened sealing effectiveness and the bonding strength between Felt and the plate.
Said sandwiched plate is a centrifugally glass-wool.
Said color steel panel and zinc-plated backboard are that clamping forms.
The back of said zinc-plated backboard has the V font, and the V font design at backboard back is when strengthening Felt intensity, because there is cavity in intralamellar part, also more favourable to the absorption of low-frequency sound.
This sound barrier sound absorption scope is big, and sound absorption coefficient is high, can control noise well, and it can also weaken solid-borne sound and the caused vibration of empty chamber gas sound except that absorbing air, and in addition, this product is light and handy, is convenient to install and transportation.
Beneficial effect: the utility model compared with prior art, its remarkable advantage is: this color steel sandwich sound barrier is rational in infrastructure, intensity is big, saves material, in light weight, acoustically effective is good.

Fig. 1 is the structural representation of the utility model;
Fig. 2 is the lateral view of the utility model;
Fig. 3 is the structural representation of panel and backboard in the utility model.
Wherein:
1, steel post; 2, chromatic steel sandwich plate; 3, Z type spring fastener; 4, color steel panel; 5, sandwiched plate; 6, zinc-plated backboard; 7, embedding formula tongue and groove structure
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
Like Fig. 1, Fig. 2 and shown in Figure 3, the described color steel sandwich sound barrier of the utility model, it comprises steel post 1, between this steel post 1, all is provided with chromatic steel sandwich plate 2, this chromatic steel sandwich plate 2 compresses with said steel post 1 through Z type spring fastener 3 and is connected; Said steel sandwich board 2 comprises color steel panel 4, sandwiched plate 5 and zinc-plated backboard 6, said color steel panel 4 and zinc-plated backboard about in the of 6 the coupling part be embedding formula tongue and groove structure 7; Said sandwiched plate 5 is a centrifugally glass-wool; Said color steel panel 4 is that clamping forms with zinc-plated backboard 6; The back of said zinc-plated backboard 6 has the V font.The utility model is rational in infrastructure, intensity is big, saves material, and in light weight, acoustically effective is good.
The utility model does not relate to all identical with the prior art prior art that maybe can adopt of part to be realized.
