Description
Technical field
The utility model relates to a kind of traffic acoustic barrier device, especially a kind of high noise reduction sound absorbing-insulating.
Background technique
With the development of China's communication, the means of transportation such as overhead road of city, highway, urban ground track it is quick
Development, traffic noise pollution are also got worse.It has been mounted with around along arterial traffic near expressway, light rail and high-speed rail
Various absorbent lined barriers.Panel and backboard is generally arranged in present absorbent lined barrier board, and panel and backboard are all made of slab construction, panel
On be provided with sound-absorbing hole, skeleton is set between panel, backboard, sound-absorbing porous material is set between skeleton.However, with panel,
The more and more thinner development trend of plate thickness is carried on the back, the thickness of absorbent lined barrier board also increasingly causes the common concern of designer.But
This can significantly increase the dosage of material, and the weight of shield plates can also increase much therewith.
As sound absorbing-insulating baffle is that the means of transportation such as existing overhead road of city, highway, urban ground track must match
Facility；Plane sound absorbing member of the existing absorbing sound and lowering noise product mostly with metal surface through punching, spray treatment, piercing aperture is 2
Within the scope of~2.5mm, this sound absorbing-insulating baffle sound sucting band is narrow, and sound absorption effect is unobvious, and component is connect with component
Place often has leakage voice phenomenon to generate, and the noise reduction effect of integrated engineering is made to decrease.
CN202081398 U provides the good sound absorbing-insulating baffle of a kind of acoustic frequency bandwidth, sound absorption effect.Including panel
And backboard, the panel are equipped with multiple perforation, further include skeleton, the panel and backboard are attached separately on the skeleton,
A cavity is formed between the panel and backboard, is equipped with sound-absorbing material in the cavity.Face, backboard make to shield with skeleton fixation respectively
Baffle has stronger external force resistance weight bearing power, and sound-absorbing material is arranged between panel and backboard.Existing sound absorbing-insulating
There is the product using perforated metal panel or macromolecule polymeric material preparation.Panel and back are installed respectively in the acoustic board two sides
Plate, the panel are aluminium sheet, and the backboard is galvanized sheet, and the reflection sound intensity is still too strong.
Utility model content
The utility model aim is to provide a kind of high noise reduction sound absorption and insulation screen, and noise reduction can achieve 30DB or more, is a kind of
The good acoustic screen of sound bandwidth, sound absorption effect, and structurally reasonable, intensity meets the requirements, and saves material, it is at low cost, it is conducive to big
The application of scale.
Technical solutions of the utility model：A kind of high noise reduction sound absorption and insulation screen is the steel column of I-shaped including cross section, in institute
It states and is equipped with horizontal skeleton between adjacent steel column, sound absorption and insulation is fixedly mounted between the skeleton and the crack of adjacent steel column
Plate, the sound absorption and insulation plate include panel, sound absorption and insulation layer and backboard, and the panel is the glass magnesium board of uniform pore openings, sound absorption every
Sound layer is that cement board adds EPS soft board, and the backboard is glass magnesium board；The surface uniform pore openings of cement board, foam water
The thickness of mud plate and EPS soft board is 17-23mm.EPS soft board is flexible foamed polystyrene board, abscess 5-10mm；
It can be using the foaming of existing soft package material and the specification of hardness.EPS soft board decays to the sound-absorbing of 80-200Hz low frequency
Preferably.
Beneficial effect：The utility model compared with prior art, the most easy steel structure support of use and most simple and efficient
Sound absorption and insulation layer, at low cost, structurally reasonable, intensity is big, save material, it is light-weight, in use, using the sound absorption of combined type
Sound insulation effect is good, and the material cost than the acoustic screen of the steel-aluminum structure of existing mainstream sound absorption cotton structure is low by 50% or more, peace
Dress and infrastructure cost want low 60%, and soundproof effect is more preferable, and the noise bandwidth of 100-5000Hz, which can be inhaled, makes an uproar, and can reach 30DB
Decaying.
Detailed description of the invention
Fig. 1 is the cross-sectional structure schematic diagram of the utility model.
Specific embodiment
As shown in Figure 1, the utility model includes steel column 1, it is the two sides gap of " I " fonts steel column 1 in the cross section
Sound absorption and insulation plate is clamped at 2,2 width of gap of " I " fonts steel column is slightly larger than the thickness of sound absorption and insulation plate, and overall thickness is
50-65mm；Sound absorption and insulation screen is also contemplated that the installation foundation of steel column during installation, and installation foundation is the slot of " I " fonts, with
Be inserted into " I " fonts steel column, be equipped with lateral skeleton 5 (spread out beam) between the steel column transverse direction, every piece of sound absorption every
The height of sound plate is unlikely to too high, 50cm or so, and upper one layer of sound absorption and insulation plate, the suction is fixedly mounted again on the beam that spreads out
Sound sound insulationg board includes panel, sound absorption and insulation layer and backboard glass magnesium board, and the panel is the glass magnesium board of uniform pore openings, plate thickness 2-4mm,
Aperture is the aperture of 5-7mm, and percent opening (area of the hole area than plate) reaches 30-35% on panel 4；Hair in sound absorption and insulation layer
Soaked mud plate 3 is by Yancheng emerald novel wall material Co., Ltd or the production preparation of Fu Wan company：Cement board is cut
It is formed after thin plate, abscess is uniformly distributed in plate plane, with a thickness of 23mm.
Sound absorption and insulation layer is cement board 3 plus EPS soft board 3-1, and the backboard is glass magnesium board, among the steel column
Sound absorption and insulation plate at the top of overhead guard is installed；The surface uniform pore openings of cement board.EPS soft board is flexible foamed polyphenyl second
Alkene plate；It can be using the foaming of existing soft package material and the specification of hardness.Sound-absorbing of the EPS soft board to 80-200Hz low frequency
Decaying is preferable.EPS soft board is more preferable also to need to wrap up layer of glass cloth in flexible foamed polystyrene board.Glass magnesium board is thick
Degree is 2-3mm.
Although the utility model has been disclosed with preferred embodiment as above, so it is not intended to limit the utility model.This reality
It is without departing from the spirit and scope of the utility model, each when that can make with novel those of ordinary skill in the art
Kind changes and retouches.Therefore, the protection scope of the utility model is subject to view those as defined in claim.
