Description
Technical field
The utility model relates to a kind of road sound insulation sound insulation slab.
Background technology
Vehicle road travelled in today that vehicle increases severely day by day gets more and more, and the normal life that the noise produced to make vehicle does not affect road both sides resident can arrange sound insulation slab in road both sides usually.But the sound insulation slab at present road used its carry out sound insulation mainly through Sound-proof material, real noise reduction can not be accomplished, and its soundproof effect neither be very desirable.
Utility model content
The purpose of this utility model is to provide a kind of road sound insulation sound insulation slab, its structure is simple, easy for installation, can not only sound insulation and can noise reduction, by hush pipe, sound insulation slab and bloop with the use of the object reaching noise reduction, improve the Practical Performance of sound insulation slab.
In order to achieve the above object, the technical solution of the utility model is:
A kind of road sound insulation sound insulation slab, comprise sound insulation slab body, described sound insulation slab body is made up of sound-absorbing aperture layer, noise reduction layer, puigging, topping, and described noise reduction layer is connected with sound-absorbing aperture layer, puigging respectively, and described puigging is connected with topping; The first sound insulation slab, the second sound insulation slab is separately installed with in described noise reduction layer, described first sound insulation slab and sound-absorbing aperture layer surround the first noise reduction cavity, described first sound insulation slab and the second sound insulation slab surround the second noise reduction cavity, and described second sound insulation slab and puigging surround the 3rd noise reduction cavity; Be provided with hush pipe in described sound insulation slab body, described hush pipe is connected with the first noise reduction cavity and arranges, and described first sound insulation slab offers the first bloop, described second sound insulation slab offers the second bloop.
Hush pipe in described first noise reduction cavity offers the 3rd bloop.
Sound insulation slab body between described second sound insulation slab and puigging offers the 4th bloop, described 4th bloop is provided with dust cover.
Described second sound insulation slab offers 2 the second bloops, described the first sound insulation slab between 2 the second bloops offers 1 the first bloop.
Described sound-absorbing aperture layer offers sound-absorbing groove.
The beneficial effects of the utility model are: a kind of road sound insulation sound insulation slab, its structure is simple, easy for installation, can not only sound insulation and can noise reduction, by hush pipe, sound insulation slab and bloop with the use of the object reaching noise reduction, improve the Practical Performance of sound insulation slab.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Embodiment 1
A kind of road sound insulation sound insulation slab as shown in Figure 1; comprise sound insulation slab body 1; described sound insulation slab body 1 is made up of sound-absorbing aperture layer 2, noise reduction layer, puigging 3, topping 4, and described noise reduction layer is connected with sound-absorbing aperture layer 2, puigging 3 respectively, and described puigging 3 is connected with topping 4.Described sound-absorbing aperture layer 2 offers sound-absorbing groove 16.Arranging of sound-absorbing groove 16 can noise reduction.
The first sound insulation slab 5, second sound insulation slab 6 is separately installed with in described noise reduction layer, described first sound insulation slab 5 surrounds the first noise reduction cavity 7 with sound-absorbing aperture layer 2, described first sound insulation slab 5 and the second sound insulation slab 6 surround the second noise reduction cavity 8, and described second sound insulation slab 6 surrounds the 3rd noise reduction cavity 9 with puigging 3.Be provided with hush pipe 10 in described sound insulation slab body 1, described hush pipe 10 is connected with the first noise reduction cavity 7 and arranges.Described second sound insulation slab 6 offers 2 the second bloops 13, described the first sound insulation slab 5 between 2 the second bloops 13 offers 1 the first bloop 12.Sound insulation slab body 1 between described second sound insulation slab 6 and puigging 3 offers the 4th bloop 14, described 4th bloop 14 is provided with dust cover 15.Hush pipe 10 in described first noise reduction cavity 7 offers the 3rd bloop 11.When the noise do not eliminated by sound-absorbing groove 16 adds noise reduction layer from hush pipe 10, due to the hush pipe 10 in the first noise reduction cavity 7 offering the 3rd bloop 11, therefore accelerate the speed that noise reduction layer abates the noise.When noise enters the first noise reduction cavity 7 from hush pipe 10 because the first sound insulation slab 5 offers 1 the first bloop 12, therefore noise can only enter the second noise reduction cavity 8 from the first bloop 12.Second sound insulation slab 6 offers 2 the second bloops 13, noise can enter the 3rd noise reduction cavity 9 from the second bloop 13.Dissipate because the first bloop 12 and the second bloop 13 shift to install to cause noise acoustic energy in transmittance process to rub in hole and change into thermal energy consumption.
A kind of road sound insulation sound insulation slab of the present embodiment, its structure is simple, easy for installation, can not only sound insulation and can noise reduction, by hush pipe, sound insulation slab and bloop with the use of the object reaching noise reduction, improve the Practical Performance of sound insulation slab.
