Abstract
A vertical sound barrier adopts a structure including an upper seal plate, H-shaped steel upright posts, acoustic boards, aluminum decorative hold-down strips and a lower seal plate, wherein, the aluminum decorative hold-down strips wrap the peripheries of a lower part acoustic board, a middle part acoustic board and an upper part acoustic board respectively; the lower part acoustic board, the middle part acoustic board and the upper part acoustic board which are well wrapped by the aluminum decorative hold-down strips are sequentially inserted into a groove between the H-shaped steel upright posts; the upper part acoustic board and the top ends of the H-shaped steel upright posts are covered with the upper seal plate; and a fixing bolt is arranged on one side of each of spaces among the H-shaped steel upright posts and the lower part acoustic board, the middle part acoustic board or the upper part acoustic board. Due to the adoption of a cement and wood chip concrete mixed structure, the manufacturing cost is reduced, the wind resistance is even, the load is huge, the sound absorption effect is good, the sound transmission loss is larger than 24dB (A); and the appearance is attractive after the surface is coated, and the utility model meets the needs of urban construction.
Description
Technical field
A kind of vertical sound barrier of the utility model, what relate to is noise elimination, sound insulation technical field, particularly road noise barrier design and manufacturing technology field is used for road noise elimination, sound insulation.
Background technology
The road of modern city except that ground level road, has been built a large amount of elevated road and speedway again, vehicular traffic is to the resident and the commercial office space of both sides, the noise that brings increases, increases, and people's live and work has been brought great influence, and resident's suggestion is very big.Modern designs in road construction, has fully taken into account the harmfulness of traffic noise, for this reason, in the both sides of some roads, especially in the elevated road both sides, sound barrier is set.Normally used sound barrier mostly adopts the main material of plastic plate as sound barrier, and it is poor that this sound barrier exists sound absorption function, and soundproof effect is unsatisfactory, exposes outside, exposes to the sun and rain, and is aging easily, the open defect that application life is short, the visual field is poor.
The utility model content
The utility model is improved existing sound barrier in order to overcome above-mentioned defective, and the structure of utilizing cement and wood chip concrete to mix is formed a kind of vertical sound barrier of acoustical board.Its technology is achieved in that and comprises upper sealing panel, the H steel post, acoustical board, decorate aluminium layering, the lower seal plate is in interior structure, it is characterized in that: decorate aluminium layering and wrap up the bottom acoustical board respectively, the middle part acoustical board, around the acoustical board of top, insert in order in the groove between the two H steel posts and wrapped up the bottom acoustical board of decorating aluminium layering, the middle part acoustical board, the top acoustical board, upper sealing panel covers top acoustical board and H steel post top, H steel post and bottom acoustical board, the middle part acoustical board, side between the acoustical board of top is respectively equipped with set bolt, and acoustical board is the platy structure that cement and wood chip concrete mix.The positive effect of implementing after this technology is: at first be to have overcome above-mentioned defective, because the structure that adopts cement and wood chip concrete to mix has reduced cost of production, the wind resistance uniformly distributed load is big, and sound-absorbing effect is good, sound transmission loss＞24dB (A); Spraying back, surface is aesthetic in appearance, meets the needs of urban construction.
Description of drawings
Fig. 1 is a side-looking sectional structure schematic diagram of the present utility model;
Wherein, 1-upper sealing panel, 2-H steel post, 3-top acoustical board, 4-middle part acoustical board,, 5-decorates aluminium layering, 6-bottom acoustical board, 7-lower seal plate, 8-set bolt;
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described:
See accompanying drawing 1, whole sound barrier is fixed on the crash bearer of bridge both sides by front and back two H steel posts (2), forms by length splicing sound barrier; Decorate aluminium layering (5) and wrap up bottom acoustical board (6) respectively, middle part acoustical board (4), top acoustical board (3) all around, insert in order in the groove between the two H steel posts (2) and wrapped up the bottom acoustical board (6) of decorating aluminium layering (5), middle part acoustical board (4), top acoustical board (3), upper sealing panel (1) covers top acoustical board (3) and H steel post (2) top, H steel post (2) and bottom acoustical board (6), middle part acoustical board (4), side between the top acoustical board (3) is respectively equipped with set bolt (8), bottom acoustical board (6), middle part acoustical board (4) and top acoustical board (3) material are the platy structure that cement and wood chip concrete mix.
See accompanying drawing 1, whole sound barrier is fixed on the crash bearer of bridge both sides by front and back two H steel posts (2), forms by length of span plug-in mounting sound barrier parts; Decorate aluminium layering (5) and wrap up bottom acoustical board (6) respectively, middle part acoustical board (4), top acoustical board (3) all around, insert in order in the groove between the two H steel posts (2) and wrapped up the bottom acoustical board (6) of decorating aluminium layering (5), middle part acoustical board (4), top acoustical board (3), upper sealing panel (1) covers top acoustical board (3) and H steel post (2) top, set bolt (8) relies on H steel post (2) to compress and fixing bottom acoustical board (6), middle part acoustical board (4), top acoustical board (3), upper sealing panel (1) covers top acoustical board (3) and H steel post (2) top.
When connecing an automobile by bridge for one, most noise that automobile sent is insulated against sound by sound barrier and is absorbed sound by acoustical board, the noise that spreads out of reduces greatly, influence degree to the resident greatly reduces, according to test, sound insulation factor＞24dB has reached the purpose of sound insulation, noise elimination and has expanded driver's the visual field, helps safety traffic.
Claims (1)
1. vertical sound barrier, the structure that comprises upper sealing panel, H steel post, acoustical board, decoration aluminium layering, lower seal plate, it is characterized in that: decorate aluminium layering and wrap up respectively around bottom acoustical board, middle part acoustical board, the top acoustical board, insert in order in the groove between the two H steel posts and wrapped up bottom acoustical board, middle part acoustical board, the top acoustical board of decorating aluminium layering, upper sealing panel covers top acoustical board and H steel post top, and the side between H steel post and bottom acoustical board, middle part acoustical board, the top acoustical board is respectively equipped with set bolt.
