Description
Technical field
The utility model relates to a kind of device shielded for urban road and bridge traffic noise, specifically a kind of road and bridge sound arrester.
Background technology
Along with socioeconomic development, city size constantly expands, and as the viaduct of urban highway traffic main line, viaduct directly runs in the guide between city high rise building mansion, to the school being in roadside, the places such as office premises, noise has become new pollution sources, people will be in automobile for a long time, among the noise pollution of train, this will have a strong impact on the school of people, work and rest, current way is at viaduct, the roadside of viaduct arranges baffler, traditional baffler generally adopts metal sheet manufacture, weight is large, install and compare effort, and soundproof effect has much room for improvement.
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 road and the bridge sound arrester that improve soundproof effect.
For achieving the above object, the technical solution adopted in the utility model is: it comprises at least two the H profile steel columns be fixed on anticollision barrier and the soundproofing member be installed between two H profile steel columns, described soundproofing member comprises sound barrier and at least two pieces of acoustical boards, described acoustical board is installed on the two ends up and down of sound barrier respectively, described acoustical board is respectively arranged with the some shutters arranged in matrix with its integrative-structure on the surface, each shutter while be connected with acoustical board upper surface, it is 45 ° of angles that another side tilts with the upper surface of acoustical board, the shutter of same vertical setting of types is shutter type.
Further, described sound barrier is made up of transparent PC plate and aluminum alloy frame.
Further, also comprise and be installed on the U-shaped steel buckle of steel post upper end for fixing sound barrier and acoustical board.
Further, described acoustical board surface has sound-absorbing hole, described sound-absorbing hole be all blocked plate hide.
The utility model has following beneficial effect: the U-shaped steel buckle of two H profile steel columns of the present utility model and upper end forms a framework, soundproofing member 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.
Accompanying drawing explanation
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.
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 and Figure 2, a kind of road and bridge sound arrester, comprise at least two the H profile steel columns 2 be fixed on anticollision barrier 1 and the soundproofing member be installed between two H profile steel columns 2, H profile steel column 2 is fixed on above the anticollision barrier 1 in roadside by screw (high-strength bolt boring), mounting distance between two H profile steel columns 2 can be determined according to the dimensions of soundproofing member, soundproofing member comprises sound barrier and at least two pieces of acoustical boards 3, and acoustical board 3 is installed on the two ends up and down of sound barrier respectively.
Acoustical board 3 surface has sound-absorbing hole (not shown), the surface of this acoustical board 3 is provided with the some shutters arranged in matrix with its integrative-structure, each shutter while be connected with the upper surface of acoustical board 3, it is 45 ° of angles that another side tilts with the upper surface of acoustical board 3, the shutter of same vertical setting of types is shutter type, this sound-absorbing hole is all hidden by these shutters, the shutter of integrative-structure is provided with on acoustical board 3 surface, after sound enters shutter, just can within it carelessly reflect in wall, until the energy of most of sound wave all consumes, become heat energy, reach good sound-absorbing effect.The sound-absorbing hole of the surface of steel plate plate that is all blocked hides, and in airborne dust and rain spraying environment, its sound absorption function is unaffected, adds service life.
Sound barrier is made up of transparent PC plate 4 and aluminum alloy frame 5, and the sound barrier of sound barrier selects transparent PC plate, transparency 95%, and effect is transparent daylighting, ensures that sight line is open, avoids causing Driver Vision tired.Select transparent PC plate to have good daylighting and the visual field, lighter in weight (10 ~ 20kg/ ㎡), 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 acoustical board 3, noise can also be prevented from the gap seepage between sound barrier and acoustical board 3, affect the soundproof effect of soundproofing member.
The utility model preferably also comprises the U-shaped steel buckle 6 being installed on H steel post 2 upper end, the two ends of U-shaped steel buckle 6 form a framework respectively by being bolted on H profile steel column 2, in installation process, first H profile steel column 2 being bolted on crashproofly protects above 1 hurdle, then first one piece of acoustical board 3 is installed on two clip-on positions of H profile steel column 2, middle installation one piece of sound barrier, top installs one piece or two pieces of block acoustical boards 3 again, afterwards by the fixing top of U-shaped steel buckle 6, 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 H profile steel column 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.
