Abstract
The utility model discloses a kind of composite material light sound barriers, including light ceramsite concrete backboard, pass Reactive Powder Concrete RPC panel and the zigzag expanded perlite sound-absorbing material plate being embedded within backboard and panel；It is fixed with reinforced mesh in the back plate of backboard, the outer end of upper plate and lower plate, which is fixed with, is mutually inserted the protrusion being fixed together and groove or groove and protrusion；The front end of backboard is fixed with pass Reactive Powder Concrete RPC panel between the upper and lower plates；Backboard and panel form closed cavity, and cavity, which is embedded in, is fixed with zigzag expanded perlite sound-absorbing material plate, and sawtooth one end of zigzag expanded perlite sound-absorbing material plate is directed at panel, and layer of glass hydrophobic cloth is fixed between panel.The utility model surface density is small, from heavy and light, has the function of that normal concrete sound barrier, structure and properties comply fully with the requirement of GB/T 3122-2010；Production, transport are low with installation cost.
Description
Technical field
The utility model relates to a kind of sound barriers.
Background technique
In recent years, with the rapid development that China's traffic transporting facility is built, noise pollution is got worse, to keep road attached
The life of nearly resident can from the influence of noise pollution, sound barrier product because its unique advantage plays huge effect, it
It is the optimal sound insulation acoustic treatment facilities of modern city.
The major product type of sound barrier has: metal sound barrier, concrete acoustical barrier, PC sound barrier, glass fiber reinforced plastic sound barrier
Deng.In these types, the more other kinds of sound barrier of concrete acoustical barrier has that easy processing, easy to maintain, the service life is long, low cost etc.
The advantage of aspect is always the principal mode of sound barrier.
All there is a disadvantages for current most of concrete acoustical barrier, i.e. surface density is high, and surface density height will lead to
Sound barrier product from great, this not only can transport, installation to product bring big inconvenience, since railroad bridge is by load
Conditional facility, and need to bear a large amount of load on bridge, such as train, track, contact net, trench cover, sound barrier etc. are various
Weight load can bear the conditional facility of load to bridge etc. and cause huge load.It is small and have to develop a kind of surface density
The composite material light sound barrier of concrete acoustical barrier general characteristic has been imperative.
Utility model content
The purpose of this utility model is exactly to solve the above-mentioned problems in the prior art, provide a kind of surface density it is small, from
Heavy and light and the composite material light sound barrier with normal concrete sound barrier function.
To achieve the above object, the technical solution of the utility model is: a kind of composite material light sound barrier, including
Light ceramsite concrete backboard, pass Reactive Powder Concrete RPC panel and the zigzag that is embedded within backboard and panel are swollen
Swollen perlite sound-absorbing material plate；Backboard is five panels, is fixed with reinforced mesh in back plate, and the outer end of upper plate and lower plate is fixed
Have and is mutually inserted the protrusion being fixed together and groove or groove and protrusion；The front end of backboard is fixed between the upper and lower plates
Pass Reactive Powder Concrete RPC panel；Backboard and panel form closed cavity, and cavity, which is embedded in, is fixed with zigzag expansion treasure
Sawtooth one end of pearl rock sound-absorbing material plate, zigzag expanded perlite sound-absorbing material plate is directed at panel, and fixed between panel
Layer of glass hydrophobic cloth.
It is further preferred that one end in the upper plate and lower plate of the backboard close to panel is fixed with horizontal tectonics muscle.Increase
The intensity in the strong corner, increases service life.
The panel of the utility model uses concrete crushing strength to be evenly distributed with made of the Reactive Powder Concrete of C70 or more
The thin-walled plate of taper borehole structure, backboard use concrete crushing strength to be thin made of the light ceramsite concrete of C30 or more
Siding, cavity are embedded in the zigzag expanded perlite sound-absorbing material plate with good sound absorption effect, and surface density is compared general
Logical concrete acoustical barrier surface density is small, is 90~100kg/m2 , surface density is small, from heavy and light, has normal concrete sound barrier
Function, structure and properties comply fully with the requirement of GB/T 3122-2010.The utility model can be effectively reduced sound
Production, transport and the installation cost of barrier, suitable for concrete acoustical barrier in need section, it is a variety of right to be especially adapted for use in
Bear the conditional facility of load.
Detailed description of the invention
Fig. 1 is the main view of the utility model；
Fig. 2 is the AA cross-sectional view of Fig. 1；
Fig. 3 is the BB cross-sectional view of Fig. 1.
Specific embodiment
The utility model is further described in the following with reference to the drawings and specific embodiments.
As shown in Figure 1, Figure 2 and Figure 3, the present embodiment includes light ceramsite concrete backboard 5, pass Reactive Powder Concrete
RPC panel 6 and the zigzag expanded perlite sound-absorbing material plate 4 being embedded within backboard 5 and panel 6.Backboard 5 is five panels,
Be fixed with reinforced mesh 2 in its back plate, the outer end of upper plate and lower plate be fixed be mutually inserted the raised 7(being fixed together or
Groove) and groove 8(or protrusion).Preferably, one end in the upper plate of the backboard 5 and lower plate close to panel 6 is fixed with level
Construct muscle 1.The front end of backboard 5 is fixed with pass Reactive Powder Concrete RPC panel 6 between the upper and lower plates.Backboard 5 and face
Plate 6 forms closed cavity, and cavity, which is embedded in, is fixed with zigzag expanded perlite sound-absorbing material plate 4, zigzag expanded perlite
Sawtooth one end of sound-absorbing material plate 4 is directed at panel 6, and layer of glass hydrophobic cloth 3 is fixed between panel 6.
Above-described embodiment be only it is preferred and illustrative, those skilled in the art can carry out according to the description of this patent
The improvement of equivalent technologies, within the protection scope of the present patent.
