Description
Technical field
The utility model relates to a kind of device shielded for urban road and bridge traffic noise, specifically a kind of noise barrier.
Background technology
At present, along with the continuous growth of vehicles number and the development of the main line of communication, the pollution of noise and harm cause the attention of people day by day, and four overall situation being listed in the world today one of are polluted, since the seventies, the control of noise pollution is included in government work by China, and adopts corresponding Preventing Countermeasures and control measure, makes noise pollution obtain effective control, in many Measures on Noise Controls, sound barrier is a kind of main measure in control noise engineering.But now common sound barrier, structure is simple, the limited efficiency of sound insulating and absorbing, and barrier is airtight light tight structure, makes the sight line of driving vehicle have limitation simultaneously.
Utility model content
For the defect that above-mentioned background technology exists, technical problem to be solved in the utility model is to provide a kind of noise barrier improving soundproof effect, and its structure is simple, and translucent effect is good.
For achieving the above object, the technical solution adopted in the utility model is: it comprises at least two steel posts and is installed on the sound insulation body between two steel posts, also comprise and be installed on the U-shaped steel buckle of steel post upper end for fixing sound insulation body, described steel post comprises the vertical portion of bottom and the curved portions on top, described sound insulation body comprises from bottom to top order peace successively and holds acoustical board, sound barrier and upper acoustical board, described sound barrier is made up of transparent PC plate and aluminum alloy frame, described lower acoustical board, quieter material is filled with in upper acoustical board, described lower acoustical board, upper acoustical board surface is respectively equipped with sound-absorbing hole.
Further, described steel post is H profile steel column.
Further, described lower acoustical board, the surface of upper acoustical board are respectively equipped with some shutters, and described sound-absorbing hole is all hidden by these shutters.
Further, described quieter material is glass wool.
The utility model has following beneficial effect: the U-shaped steel buckle of two steel posts of the present utility model and upper end forms a framework, sound insulation body is directly installed in framework, convenient installation, dismounting and maintenance, soundproofing member adopts the combination of sound barrier and acoustical board can reach the effect reducing noise, transparent reflection-type sound barrier is used in the middle of sound insulation body, effectively can interrupt the route of transmission of sound wave, simultaneously also for driver and resident provide an open visual field environment.

In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is schematic front view of the present utility model.
Fig. 2 is schematic side view of the present utility model.
Fig. 3 is the structural scheme of mechanism of the acoustical board in the utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
As shown in Figure 1 to Figure 3, a kind of road and bridge sound arrester, comprise at least two steel posts 2 be fixed on anticollision barrier 1 and the sound insulation body be installed between two steel posts 2, steel post 2 is H profile steel column, steel stands, 2 comprise the vertical portion 21 of bottom and the curved portions 22 on top, steel post 2 is fixed on above the anticollision barrier 1 in roadside by screw (high-strength bolt boring), mounting distance between two steel posts 2 can be determined according to the dimensions of soundproofing member, also comprises and is installed on the U-shaped steel buckle 7 of steel post 2 upper end for fixing sound insulation body.
Sound insulation body comprises from bottom to top order peace successively and holds acoustical board 3, sound barrier 4 and upper acoustical board 6, sound barrier is made up of transparent PC plate and aluminum alloy frame 5, the sound barrier of sound barrier selects transparent PC plate, transparency 95%, effect is transparent daylighting, ensures that sight line is open, avoids causing the tired energy of Driver Vision, and effectively interrupt the route of transmission of sound wave, simultaneously also for driver and resident provide an open visual field environment.Transparent PC plate is selected to have good daylighting and the visual field, lighter in weight (10 ~ 20kg/m
2), have enough intensity, life-span length can use more than 15 years.Aluminum alloy frame 5 not only plays the fastening effect of sound barrier and upper and lower acoustical board, noise can also be prevented from sound barrier and the gap seepage up and down between acoustical board, affect the soundproof effect of sound insulation body.
Quieter material is filled with in described lower acoustical board 3, upper acoustical board 6, it is also respectively equipped with sound-absorbing hole (not shown) on the surface, the surface of lower acoustical board 3 and upper acoustical board 6 is also respectively equipped with some shutters 8, described sound-absorbing hole is all hidden by these shutters 8, and preferably, the quieter material that the utility model adopts is glass wool, the acoustical board sound absorption coefficient adopting this material to make is high, after tested, its sound absorption coefficient can reach 0.75-0.95, and sound insulation factor can reach 32-33.6dB.
The two ends of U-shaped steel buckle 7 of the present utility model form a framework respectively by the upper end of the curved portions 22 being bolted to H profile steel column 2, in installation process, first steel post 2 being bolted on crashproofly protects above 1 hurdle, then first lower acoustical board 3 is installed on two clip-on positions of H profile steel column 2, middle installation sound barrier 4, top installs acoustical board 6 on a piece or two pieces of blocks again, afterwards by the fixing top of U-shaped steel buckle 7, this device is not only easy for installation and removal and safeguards, and consider that it is often used in outdoor environment, in order to not allow the flow-disturbing of strong wind or vehicle, its firmness is impacted, the framework of steel post of the present invention and U-shaped steel buckle composition, can to self playing preferably supporting function, there will not be unnecessary rocking or covibration, extend application life.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
