To have preferable sound insulation and acoustical absorptivity.
Selectable, ETFE pneumatic die cushions can use double-deck or multilayer pneumatic die cushion form, and double-deck ETFE pneumatic die cushions have two layers of ETFE film, more
Layer ETFE pneumatic die cushions have 3~4 layers of ETFE films.After the inflation of multilayer membrane material, the ability of sound reflecting can be improved, is finally realized on road
Efficient sound insulation.
Furthermore ETFE pneumatic die cushion printing opacities are higher, individual layer membrane material light transmittance is up to 95%；Reflective is weak, can reduce light pollution；It is anti-
Dirt is good, and main dirt can be removed by rainwater, can effectively improve the visual effect on overpass；ETFE pneumatic die cushions can
Recyclability is good, and ETFE membrane materials utilize material to be recyclable, green reusable.
Referring to Fig. 1, it show a kind of structural representation for overhead sound insulation system that this example is provided based on above-mentioned principle.
The overhead sound insulation system is mainly used on overpass, using enclosed construction, to ensure soundproof effect.Can by figure
Know, the overhead sound insulation system mainly includes vertical acoustic insulating unit 1 and the two parts of top acoustic insulating unit 2.
Wherein, vertical acoustic insulating unit 1 is arranged on the both sides of overpass 3, and overhead road is obstructed from the two sides of overpass 3
Noise dissipates to aerial caused by vehicle traveling in road 3；Simultaneously top acoustic insulating unit 2 connect overpass 3 both sides it is vertical every
The top of sound unit 1, noise caused by vehicle traveling dissipates to aerial from the top of overpass 3 barrier overpass 3, this
Sample coordinates with vertical acoustic insulating unit 1, a closing sound deadening space is formed on overpass 3, sound insulation region becomes from both sides of the road
For both sides and top, the sound transmission loss on overpass is significantly improved.
Vertical acoustic insulating unit 1 is formed with ETFE pneumatic die cushions 11 and vertical lattice support structure 12 in this example.
Here, vertical lattice support structure 12 forms the vertical main body rack of acoustic insulating unit 1, latticed supporting construction,
Vertical acoustic insulating unit is formed to carry ETFE pneumatic die cushions with grid therein, while the bearing capacity of sound insulation system can also be improved.
For grid in vertical lattice support structure 12 shape can according to the actual requirements depending on, as an example, the grid

Visual effect, reduction light pollution on overpass.
The vertical acoustic insulating unit 1 so formed effectively can be separated from overhead both sides to noise.
Top acoustic insulating unit 2 is formed with ETFE pneumatic die cushions 21 and top grid supporting construction 22 in this example.
Here, top grid supporting construction 22 forms the top main body rack of acoustic insulating unit 2, the latticed support knot
Structure, vertical acoustic insulating unit is formed to carry ETFE pneumatic die cushions with grid therein, while the carrying energy of sound insulation system can also be improved
Power.
In addition, the entirety of top grid supporting construction 22 in this example uses domes, so as to perpendicular with overhead 3 both sides
Straight acoustic insulating unit 1 coordinates.
For grid in top grid supporting construction 22 shape can according to the actual requirements depending on, as an example, the grid
Supporting construction can use triangle, quadrangle or hexagonal mesh support system.
In addition, the distribution for grid in top grid supporting construction 22, can according to the actual requirements depending on, it is only necessary to can
So that ETFE pneumatic die cushions form effective distribution in top grid supporting construction 22, vertical acoustic insulating unit is formed, and reach good
Soundproof effect, as an example, array distribution can be used, be interspersed successively from top to bottom etc..
Sound insulation element of the ETFE pneumatic die cushions 21 as at the top of in acoustic insulating unit 2, it is placed in the net of top grid supporting construction 22
In lattice, by its preferable sound insulation and acoustical absorptivity, the propagation of noise on road can be farthest reduced.
Shape, the size of the ETFE pneumatic die cushions 21 are corresponding with grid in top grid supporting construction 22, can effectively dispose i.e.
Can.The ETFE pneumatic die cushions can be double-deck or multilayer pneumatic die cushion.
Individual layer ETFE membrane material light transmittances are up to 95%；In addition, the low reflecting rate of ETFE membrane materials and high self-cleaning, can be improved
Visual effect, reduction light pollution on overpass.
So the top acoustic insulating unit 2 for forming arch effectively can be separated from overhead top to noise；It is across height
Frame 3 and the vertical acoustic insulating unit 1 of overhead both sides coordinate, and totally-enclosed sound insulation region is formed on overpass, by sound insulation region from
Overpass both sides are changed into both sides and top, significantly improve the sound transmission loss on overpass, farthest reduce noise
Propagate.
