Description
Technical field
The invention belongs to sound barrier field, and in particular to a kind of bridge metal sound barrier.
Background technology
Sound barrier is, positioned at sound source and by the sound barrier structure with enough surface densities between sound point, to utilize sound source both sides
What some areas were built has limit for length's sound barrier that the running noises of sound source can be made to have a significant additional attenuation in communication process, from
And the influence of noise in the certain area where weakening recipient, to improve the sound environment quality of surrounding environment.Bridge is due to knot
Structure and the characteristics of use, has certain requirement to the gravity of the auxiliary member above it, and because some bridges are at the beginning of design
The influence of sound barrier weight is not considered, and this requires that the weight of sound barrier is the smaller the better, but must be examined on bridge simultaneously
Consider effect of the pulsating wind pressure to sound barrier that bullet train is produced, it is desirable to which sound barrier has enough intensity, and existing sound-screen
Barrier mostly is that surface plate is structure, and several pieces are one group and are inserted in default H types column and constitute a face sound barrier, due to bear at a high speed
The pulsating wind pressure that train is produced, the width of monolithic sound barrier needs to shorten many just with enough intensity；Have again and due to bridge
Difficulty of construction is big on beam, it requires that sound barrier is easily installed thereon, is not easily broken, service life is long, from operation maintenance.Mesh
Preceding metal sound barrier is mainly that aluminium alloy is external metallization skeleton, using glass fibre cotton as inner sound absorption material, due to glass
Cellucotton low intensity, therefore need that calcium silicate board is internally installed in the manufacturing process of sound barrier and be screwed strong to increase its
Degree, while being carried out integrating fixation with neck, this increases not only manufacture craft, while also increasing the weight of product.
The content of the invention
In order to overcome the deficiencies in the prior art, it is an object of the invention to provide a kind of bridge metal sound barrier.
To reach above-mentioned purpose, the present invention is achieved by the following technical solutions.
A kind of bridge metal sound barrier, including foam aluminum deck and backboard and the galvanized steel plain sheet of four sides, the bubble
Foam aluminum deck two ends are straight, and centre is the arc of outwardly convex, and the galvanized steel plain sheet is pressed into section as U-shaped section bar, foam
Aluminum deck and backboard are fixedly connected to form the metal sound barrier with cavity structure with galvanized steel plain sheet section bar.Because front is using outer
Raised arc so that the structural strength of monoblock sound barrier is greatly increased, and can make relatively wide sound barrier, foamed aluminium
Proportion is lighter, and centre has provided with cavity, can reduce weight while sound barrier width is increased, be easily installed.
It is further U-shaped strengthening rib strip provided with several sections between the foam aluminum deck and backboard.Further
Increase sound barrier structural strength and weight increase it is limited.
Further the foamed aluminium backboard is identical with panel-shaped, and arc convex direction is identical or opposite with panel.Increase
Plus the structural strength of sound barrier, the pulsating wind pressure that resistance bullet train is produced.
Further the galvanized steel plain sheet section bar above the sound barrier slightly stretches out in panel and backboard top edge, in institute
The galvanized steel plain sheet section bar below sound barrier is stated slightly to be retracted in panel and backboard lower edge.It is easy to the installation of sound barrier, after installation
Gap is not produced, and the intensity of sound barrier seam crossing can be improved.
Further the foam aluminum deck is micro through hole or fine-crystal spume aluminium alloy, and the foamed aluminium backboard is closed-cell foam
Aluminium.Panel has the effect of sound absorption damping, and backboard is used for insulating against sound.
Further filling sucting sound material in the cavity of the sound barrier.Increase sound-absorbing effect.
Further the sound-absorbing material is one kind in polyimides, polyurethane, glass fibre cotton, foamed ceramics.On
It is all Lightweight acoustical material to state material, and the weight of sound barrier will not be significantly increased.
Beneficial effect：Compared with prior art, the advantage of the invention is that：
1）Due to positive arcuate structure, compared with the sound barrier of commensurateiy wide, with higher structural strength；
2）With hollow cavity, overall weight is reduced；
3）Panel and backboard are done using foamed aluminium, more preferably, intensity is secure for acoustically effective.
