Description
Technical field
This utility model is related to Radix Saposhnikoviae sound insulation sound barrier, more specifically, it relates to a kind of closed noise barrier.
Background technology
Sound barrier refers to the facility inserted between sound source and recipient, makes sonic propagation have one significantly to add
Decay, so as to weaken the influence of noise in the certain area that recipient is located.Sound wave in communication process, when running into sound barrier,
Will reflect, transmit and three kinds of phenomenons of diffraction.Generally it is considered that barrier can prevent through sonic propagation, and penetrate system
Sound has enough decay, and the impact of transmission sound is negligible.Therefore, the defening effect of sound barrier can typically adopt noise abatement
Amount represents that it reflects the ability that sound barrier above two shields entrant sound.A sound barrier is inserted between sound source and receiving point,
If barrier endless, sound wave diffraction can only be gone over from above barrier, and form an acoustic shadow behind, as light by object
Block that to form a shade such.In this acoustic shadow, people can feel that noise is significantly reduced, here it is sound barrier
Noise reduction effect the reason for.
Increasing highway or track traffic now has used sound barrier, to reach preferably effect, has used closing
The sound barrier of formula.China Patent No. is：ZL201110369849.2, November 18 2011 date of application, denomination of invention：Closing
Formula sound barrier panel, discloses a kind of closed noise barrier plate, including beam column and longitudinal steel column, and the beam column is stood by horizontal steel
Post, roof support, purlin support composition, and the beam column to be fixedly connected with longitudinal steel column by longitudinal bracing；
Acoustic barrier and absorbent lined barrier are fixed between longitudinal steel column, acoustic barrier is by aluminum alloy outer frame and doubling glass plate
Composition, absorbent lined barrier are made up of skeleton, backboard and panel, and the panel and backboard are aluminium sheet, and the skeleton is galvanized sheet.Above-mentioned
It is bright with preferable acoustically effective, but which is full-enclosed structure, when vehicle is travelled inside which, because cannot be with extraneous formation
Convected air, in tail gas, contained particulate matters aggregation, causes its internal medium more dirty.
The content of the invention
1. utility model technical problem to be solved
This utility model provides a kind of closed noise barrier, it both can preferably anti-sound noise reduction function, again can be with
The pollution in sound barrier is discharged in time, it is to avoid the too high generation of local pollution.
2. technical scheme
To reach above-mentioned purpose, the technical scheme that this utility model is provided is：A kind of closed noise barrier, including framework knot
Structure, sound barrier panel, it is characterised in that the frame structure is divided into facade structures and roof structure two parts, by vertical steel column,
Laterally girder steel, roof support, purlin support composition stationary structure；The sound barrier panel includes that facade absorbent lined barrier and roofing are saturating
Bright type sound barrier panel, is respectively arranged in steel frame；Facade structures below above-mentioned facade structures and roof structure intersection
Passage is provided with, passage is provided with air filter.
Preferably, the absorbent lined barrier is made up of skeleton, backboard and panel, and the panel is punched-plate and the common die mould of backboard
Plate, skeleton are galvanized sheet.
Preferably, one kind in the absorbent lined barrier backboard and panel in filling glass cotton, mineral wool, rock wool or foamed aluminium
Sound-absorbing material.
Preferably, the transparent type sound barrier panel is the one kind or several in polycarbonate plate, acrylic board or doubling glass
Kind, its periphery is provided with frame and supports or press strip, and transparent type sound barrier panel is supported by the frame or press strip is fixed on steel frame
Lattice frames in.
3. beneficial effect
The technical scheme provided using this utility model, compared with existing known technology, is had the advantages that：
(1) absorbent lined barrier panel is punched-plate, has more preferable acoustically effective compared with surface plate.
(2) filling sucting sound material reinforcing sound absorption between facade structures absorbent lined barrier panel and backboard.
(3) roof structure sound barrier panel is transparent type sound barrier panel, can meet the demand of road light on daytime, save lighting
The energy.
(4) facade structures below the sound barrier facade structures and roof structure intersection are provided with passage, can and
When discharge sound barrier in pollution, it is to avoid the too high generation of local pollution.
(5) passage is provided with air filter, can purify the air being discharged from, the less pollution to air.
