Abstract
The utility model provides an acoustic celotex board for road and bridge is last, includes structural layer, elastic cushion, acoustic celotex board and bearing structure, elastic cushion is made by rubber materials, bearing structure is made by the aluminum material, nut fixed joint is passed through with bearing structure in the structural layer top, is equipped with elastic cushion between structural layer and the bearing structure, be equipped with the acoustic celotex board between bearing structure and the elastic cushion, the acoustic celotex board including the dust absorption layer that connects gradually, inhale sound hole, sound absorbing layer and vacuum layer. The utility model discloses a set up the dust absorption layer, can absorb the vehicle through the time dust that produces, reduce air pollution, the noise gets into the sound absorbing layer through inhaling the sound hole, then reachs the vacuum layer, can fall the noise consumption that the vehicle produced, avoids causing sound to pollute, through set up the elastic cushion who is made by rubber materials between structural layer and bearing structure, can reduce the vibrations of acoustic celotex board, the life of extension acoustic celotex board.
Description
Technical field:
This utility model relates to a kind of baffle, is specifically related to a kind of baffle on road and bridge,
Belong to road and bridge noise insulation equipment technical field.
Background technology:
Along with the fast development of industrialized production, urban environment is increasingly subject to the pollution from each side, occupies
Stay in the resident's health in city and therefore suffer from the infringement of air pollution, due to the decline of Outdoor Air Quality,
Also the quality level of city air is had influence on.Baffle is a sound insulation facility, in order to block sound source and connect
Direct sound wave between receipts person, inserts a facility between sound source and recipient, makes sonic propagation have one
Significantly additional attenuation, thus weaken the influence of noise in the certain area at recipient place.Baffle master
Outdoor to be used for, along with highway traffic noise pollutes day by day serious, the various forms of baffles of a large amount of employing
Reduce traffic noise.But the baffle used on road at present its mainly carry out sound insulation by Sound-proof material,
Real sound insulation can not be accomplished, and its soundproof effect is not highly desirable, simultaneously can not be by vehicle warp
The substantial amounts of dirt absorption of out-of-date generation, causes the pollution of environment.
Utility model content:
Technical problem to be solved in the utility model is to overcome existing technological deficiency, it is provided that Yi Zhongyong
Baffle on road and bridge, by arranging dust suction layer, can absorb the vehicle dust through out-of-date generation,
Reducing air pollution, noise enters sound absorbing layer through sound-absorption hole, then arrives vacuum layer, can be by vehicle
The noise produced consumes, it is to avoid cause sound to pollute, by arranging between structure sheaf and supporting construction
The elastic insert being made up of elastomeric material, can reduce the vibrations of baffle, extends the use longevity of baffle
Life.
Technical problem to be solved in the utility model uses following technical scheme to realize:
A kind of baffle on road and bridge, including structure sheaf, elastic insert, baffle and support
Structure, described elastic insert is made up of elastomeric material, and described supporting construction is made up of aluminum material, described
It is connected by nut is fixing with supporting construction above structure sheaf, between structure sheaf and supporting construction, is provided with elasticity
Bed course, is provided with baffle between described supporting construction and elastic insert, described baffle includes being sequentially connected with
Dust suction layer, sound-absorption hole, sound absorbing layer and vacuum layer.
Preferably, described dust suction layer is that air filtration is cotton, can absorb the vehicle dust through out-of-date generation,
Reduce air pollution.
Preferably, described vacuum layer is internal fills rare gas, can play the effect of sound insulation.
Preferably, described sound-absorption hole is irregularly shaped being arranged between sound absorbing layer and dust suction layer, increases and inhales
Sound hole and noise contact area, be lost noise.
Preferably, described sound absorbing layer is crest acoustical cotton, reduces noise further.
The beneficial effects of the utility model are: by arranging dust suction layer, can absorb vehicle through out-of-date generation
Dust, reduce air pollution, noise enters sound absorbing layer through sound-absorption hole, then arrives vacuum layer, can
So that the noise that vehicle produces is consumed, it is to avoid cause sound to pollute, by structure sheaf and supporting construction
Between the elastic insert being made up of elastomeric material is set, can reduce the vibrations of baffle, extend baffle
Service life.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
Fig. 2 is that Figure 1A-A locates cross-sectional schematic.
In figure: 1, structure sheaf；2, bed course；3, baffle；4, dust suction layer；5, sound-absorption hole；6、
Sound absorbing layer；7, vacuum layer；8, supporting construction.
Detailed description of the invention:
For the technological means making this utility model realize, creation characteristic, reach purpose and be prone to bright with effect
White understanding, below in conjunction with being specifically illustrating, is expanded on further this utility model.
As shown in Figure 1, 2, a kind of baffle on road and bridge, including structure sheaf, elastic insert,
Baffle and supporting construction, described elastic insert is made up of elastomeric material, and described supporting construction is by aluminium material
Material is made, and is connected by nut is fixing with supporting construction, structure sheaf and supporting construction above described structure sheaf
Between be provided with elastic insert, be provided with baffle, described baffle between described supporting construction and elastic insert
Including the dust suction layer, sound-absorption hole, sound absorbing layer and the vacuum layer that are sequentially connected with.
Described dust suction layer is that air filtration is cotton, can absorb the vehicle dust through out-of-date generation, reduce air
Pollute；Described vacuum layer is internal fills rare gas, can play the effect of sound insulation；Described sound-absorption hole in
Irregularly shaped it is arranged between sound absorbing layer and dust suction layer, increases sound-absorption hole and noise contact area, loss
Noise；Described sound absorbing layer is crest acoustical cotton, reduces noise further.
During utility model works, by dust suction layer, the vehicle dust through out-of-date generation can be absorbed, fall
Low air pollution, noise enters sound absorbing layer through sound-absorption hole, then arrives vacuum layer, can be produced by vehicle
Raw noise consumes, it is to avoid cause sound to pollute, by arrange between structure sheaf and supporting construction by
The elastic insert that elastomeric material is made, can reduce the vibrations of baffle, extends the service life of baffle.
Of the present utility model ultimate principle and principal character and of the present utility model excellent have more than been shown and described
Point.Skilled person will appreciate that of the industry, this utility model is not restricted to the described embodiments, above-mentioned
Principle of the present utility model is simply described, without departing from this utility model described in embodiment and description
On the premise of spirit and scope, this utility model also has various changes and modifications, these changes and improvements
In the range of both falling within claimed this utility model.This utility model claims scope by appended power
Profit claim and equivalent thereof define.
