Description
Technical field
This utility model relates to shutter technical field, it is provided that a kind of noise elimination shutter system, and provides this noise elimination BAIYE system
Louvre blade in system.
Background technology
Noise elimination shutter system of the prior art, as it is shown in figure 1, louvre blade therein 01 is square-section, this louvre blade
The core 01a of 01 is Sound-proof material, and outside cladding galvanized iron sheet 01b, galvanized iron sheet down is the galvanized iron sheet 01c of perforate.BAIYE
The effect of sheet lateral opening hole down is: can absorb noise, reduces reflection and transmission, and echo enters into the rock of intracavity by hole
In cotton, rock wool belongs to porous material and can be good at absorbing sound.
BAIYE cross sectional shape in existing shutter system is rectangle, and the spacing between louvre blade is less, is unfavorable for that air-flow passes,
Pressure drop is relatively big, causes noise bigger.Cladding iron sheet, is very easy to be corroded.
In existing shutter system, louvre blade typically all arranges U-shaped fastener, by BAIYE with the connection of framework on framework
Sheet is fastened on U-shaped fastener fixing.If U-shaped fastener is the most loose, louvre blade easily comes off, if but U-shaped fastener is too tight, install and
Dismantle the most cumbersome.

Ground, arranges attachment structure on the relevant position of described framework, this bindiny mechanism arranges screw hole solid with on described louvre blade
Described screw on fixed hush panel adaptor is corresponding, in order to be fixed on said frame by louvre blade by screw.
Described attachment structure can be the frame of framework equivalent layer, arranges described screw hole on the frame of described framework；
Or, described attachment structure can be the BAIYE fixed plate that can split with framework that on described framework, respective side edge is provided with, should
The screw hole corresponding with the screw on described hush panel adaptor, described BAIYE fixed plate and described frame are set in BAIYE fixed plate
The corresponding frame of frame arranges releasable connection structure.
Described releasable connection structure is it may be that the both sides of the edge of described BAIYE fixed plate form caulking groove so that described BAIYE
Fixed plate is embedded on said frame；Or, it is the fixed structure that is spirally connected arranged between described BAIYE fixed plate and described framework.
A kind of louvre blade, including fuse and outer cladding metallic plate, described fuse is Sound-proof material, and described metallic plate is aluminum plate
Material, on described louvre blade surface down, aluminium panels is provided with perforate；The cross sectional shape of described louvre blade is shuttle-type, i.e. both sides
Narrower, wide middle, upper and lower surface is curved surfaces.
Further, the upper and lower surface of described louvre blade is symmetrical curved surfaces.
On described louvre blade surface down, the percent opening of perforate is more than 70%.The uper side surface of described louvre blade is aluminum
Panel, downside surface is aluminum silk screen sheet material or is aluminum punching sheet material, and the edge of the aluminium panels of upside bends downwards
It is fastened on the silk screen sheet material of downside surface fixing.
Such structure i.e. can improve percent opening, can guarantee that again the intensity of plate.
Between the aluminium panels of the uper side surface of louvre blade and the aluminum silk screen on volume two surface or aluminum punching sheet material permissible
It is riveting, or is welded to connect.
Sound-proof material fuse in described louvre blade, is closed by glass-fiber-fabric parcel.
The noise elimination shutter system of this utility model offer and louvre blade therein, have the advantage that
1. use aluminium panels to be greatly improved as outer cladding metallic plate, antiseptic property, and can be squeezed by aluminium section bar
Pressure or aluminium sheet roll-forming upper surface housing and lower surface housing, make simpler compared with in prior art with galvanized iron sheet.
2. the cross sectional shape of BAIYE is shuttle-type, and the size of middle the widest part is permissible with the width of original square-section louvre blade
It is the same, but two-layer width is tapered so that ventilation rate increases, the airflow design of the upper and lower surface of arc, it is possible to make wind
Pressure pressure drop is less, and noise reduction is more preferable.
3. louvre blade makes to be connected so that shutter system is more attractive in appearance with the improvement of the attachment structure of framework, and dismounting is more
Add conveniently.
4. the uper side surface of louvre blade is aluminium panels, firmer compared with galvanized iron sheet of the prior art, it is easy to add
