Description
Technical field
A kind of ventilated type shutter of the utility model, belongs to railroad bridge protection technology field.
Background technology
Due to developing rapidly for railway, caused noise pollution is serious all the more in train travelling process.In order to reduce railway
The influence of noise, typically there is resident to occupy residence setting sound barrier, with the route of transmission of truncation noise.Noise Barrier Works are thrown
Money is suitable, and defening effect is good, it has also become controls the important measures of traffic noise pollution.
Ventilation unit used by current existing closed tunnel sound insulation protecting screen, only only draught effect, it is made
With being that inner and outer air pressure is poor when balance train passes through tunnel, and in existing construction scene, the closed tunnel of installation often position
In residential block or not far from population accumulation area, so needing to carry out noise elimination processing for the noise spread out of from tunnel.
Utility model content
The utility model overcomes the shortcomings of the prior art, there is provided and it is a kind of simple in construction, it is easy to assembly quick, have
The ventilating silencing window shade of effect.
In order to solve the above-mentioned technical problem, the technical solution adopted in the utility model is：A kind of ventilated type shutter, including
Framework and blinds, the framework is interior to be provided with the parallel blinds, and the blinds both ends are fixedly connected with the framework respectively, institute
Stating blinds includes framework and noise reduction backing member, and the framework is formed by monoblock magnesium alloy composite plate roll-in, the noise reduction backing member edge
After on stopping means, and it is collectively disposed in framework, and perforation is provided with the framework.
The blinds is parallelogram and lateral surface and the frame facet flush.
The blinds and the framework angle are 30 °~45 °.
The framework seam crossing of the blinds is pressed together by intersecting flanging by extruder.
The noise reduction backing member includes grid cloth and sound absorption cotton, and the grid cloth is glass fiber flameproof fabric, and the sound absorption cotton is
Centrifugally glass-wool.
The utility model has an advantageous effect in that compared with prior art：The utility model is Novel noise-reduction shutter,
Design structure is simple, reasonable, practical, is made of magnesium-aluminium alloy material, easy to make, combines flexible for installation, the utility model
Noise reduction backing member and framework between have space interval, train cross produce high pressure draught when, noise and air-flow are passing through blinds
When it is launched repeatedly to reduce acoustic pressure, can noise reduction also can sound-absorbing, drop requirements relatively low during smooth air flow can be met
With the requirement of effective noise control.
Brief description of the drawings
The utility model is described further below in conjunction with the accompanying drawings.
Fig. 1 is front view of the present utility model.
Fig. 2 be the utility model in A to sectional view.
Fig. 3 is side view of the present utility model.
Fig. 4 is the structural representation of the utility model blinds.
1 is framework in figure, and 2 be blinds, and 21 be framework, and 22 be noise reduction backing member, and 23 be stopping means.
Embodiment
As Figure 1-Figure 4, a kind of ventilated type shutter, including framework 1 and blinds 2, the framework 1 are interior provided with parallel
The blinds 2, the both ends of blinds 2 are fixedly connected with the framework 1 respectively, and the blinds 2 includes framework 21 and noise reduction backing member
22, the framework 21 is formed by monoblock magnesium alloy composite plate roll-in, after the noise reduction backing member 22 is embedded on stopping means 23,
And be collectively disposed in framework 21, and perforation is provided with the framework 21.
The blinds 2 is parallelogram and lateral surface and the side flush of framework 1.
The blinds 2 and the angle of framework 1 are 30 °~45 °.
The seam crossing of framework 21 of the blinds 2 is pressed together by intersecting flanging by extruder.
The noise reduction backing member 22 includes grid cloth and sound absorption cotton, and the grid cloth is glass fiber flameproof fabric, the sound absorption cotton
For centrifugally glass-wool.
The utility model blinds 2 is that monoblock magnesium alloy composite plate roll-in forms, and is made simply, easy to assembly, blinds 2 is
Riveting is fixed in framework 1.
Glass fiber flameproof fabric is alkali-free hydrophobic glass silk cloth, and it has fire prevention, the function of waterproof.
Blinds 2 and preferably 45 degree of the selection of angle folded by framework 1, more preferable ventilation and soundproof effect can be brought, at utmost
Upper reduction train is at a high speed when crossing, the impact that air pressure is brought to shutter.
Magnesium alloy composite plate is two-sided fluorocarbon-sprayed；Grid cloth parcel sound absorption cotton is arranged in stopping means.Rotary glass
Cotton unit weight error should be no more than ± 5%, and impure amount is not more than 3% acoustic absorptivity NRC >=0.95, and fibre diameter is less than 6 microns, no
Slag inclusion ball, protection against the tide, do not absorb water.
Embodiment of the present utility model is explained in detail above in conjunction with accompanying drawing, but the utility model is not limited to
Embodiment is stated, in those of ordinary skill in the art's possessed knowledge, the utility model aims can also not departed from
On the premise of various changes can be made.
