Integral aluminum alloy acoustic barrier structure unit, structure operation is safer, simple structure, easy dismounting, and absorbing effect is good, and owing to adopt industrial aluminum profile aluminum alloy hollow thin wall, make its have that the quality is light, the shaping is excellent, intensity is high, corrosion -resistant, longe -lived, can regenerate, maintenance cost low grade advantage. It can extensively be arranged in the sound barrier, plays most important effect on reducing highway railway rails traffic noise pollution along the line.
Description
Technical field
The utility model is related to a kind of integral aluminum alloy noise barrier structure unit, more particularly to a kind of integral aluminum alloy
Noise barrier structure unit, is widely used in the fields such as urban transportation track, traffic sound barrier, it can also be used to other noise source goboes
Barrier.
Background technology
Traffic noise is that urban transportation is caned not to the modernization direction evolution such as high-grade, high speed, overhead solid
The urban issues for avoiding.To eliminate or slowing down the noise pollution that railway, highway operation are produced to acoustic environment sensitive spot along the line, ensure
Numerous residents' physical and mental health along the line and normal work, life, must take effective noise reduction measure, wherein sound barrier reducing
Road and rail track traffic noise pollution along the line plays vital effect.Existing sound barrier sound absorption cell board adopts face
The scheme of sound-absorbing material is filled between plate, backboard, and is fixed using rivet, bolt or pin mode between panel, backboard, applied to engineering
Work brings very big inconvenience.
To solve the above problems, the utility model provides a kind of integral aluminum alloy noise barrier structure unit, by whole
Body formula aluminum alloy bottom plate, sieve tray and inhale the organic composite of acoustic material, overall structure need not using any fixing bolt or
Fixing, structure runs safer, simple structure, easy accessibility to pin, and sound-absorbing effect is good；And due to using industrial aluminium profiles
Material aluminium alloy hollow thin-walled so as to low with light weight, high, the corrosion-resistant excellent, intensity of shaping, life-span length, renewable, maintenance cost
The advantages of, the packaging efficiency of integral type sound barrier aluminum section bar frame is improved to greatest extent.
Utility model content
The utility model provide a kind of integral aluminum alloy noise barrier structure unit, including integral aluminum alloy base plate,
Sound-absorbing material, sieve tray；
The integral aluminum alloy base plate makes an Integral U-shaped construction unit by expressing technique, and its length can root
Need flexibly to select according to concrete engineering job site, substantially increase the packaging efficiency of sound barrier aluminum section bar frame；Coordinate local
T-shaped, y-type structure, to fix sound-absorbing material, sieve tray, and the intensity of integral type sound barrier construction unit and resistance to can be strengthened
Stress；
The integral aluminum alloy base plate adopts hollow thin-wall construction, to mitigate the weight of integral type sound barrier；
The sound-absorbing material is fixed by the U-shape structure on integral aluminum alloy base plate, and forms both sides cavity structure；
The sieve tray is fixed by the y-type structure on integral aluminum alloy base plate, is installed using board plug type；
