Description
Technical field
The present invention relates to a kind of sound-absorbing wall.
Background technology
The occasions such as current Conference Hall, studio and cinema need good acoustics, but stereo set playing sound oftenChance wall reflection, multiple reflections and cause echo, stress inside, affects audibility, therefore needs to install sound-absorbing wall; RawProduce the impact of producer for the Noise upon Environment of control indoor equipment (transformer, air compressor machine, coal pulverizer etc.) generation, generally alsoNeed be at sound-absorbing silencing apparatus such as indoor location sound-absorbing walls.
But the problem such as existing sound-absorbing wall abatvoix used exists, and sound-absorbing effect is poor, inflammable, poor stability, mounting process are loaded down with trivial details,And the dismounting of an abatvoix can make other abatvoix chain-react cause large area to come off, lack security and can safeguardProperty.
Summary of the invention
Have in order to overcome in prior art sound-absorbing wall abatvoix used that sound-absorbing effect is poor, inflammable, poor stability, mounting processLoaded down with trivial details, to lack security etc. deficiency, the invention provides a kind of sound-absorbing wall.
For addressing the above problem, the present invention adopts following technical scheme:
A kind of sound-absorbing wall, comprises interior wall, alkali-free glass acoustical cotton, sound-absorbing metal plate and keel, is provided with within the walls in described pre-buriedPart, keel are welded on built-in fitting, and sound-absorbing metal plate is fixed on keel by bolt and nut, and alkali-free glass acoustical cotton is filledBetween interior wall and sound-absorbing metal plate;
Described sound-absorbing metal plate, comprises sound-absorbing metal plate material and fire prevention alkali-free glass fiber layer, on sound-absorbing metal plate material, is evenly distributed withSound-absorption hole, the area sum of all sound-absorption hole account for sound-absorbing metal plate face long-pending more than 40%, sound-absorption hole is circular hole, sound-absorption holeInternal diameter be 4-8mm; The back side of sound-absorbing metal plate material is provided with first flanging vertical with sound-absorbing metal plate material along its periphery, theThe height of one flanging is 15-25mm; Fire prevention alkali-free glass fiber layer is located at the back side of sound-absorbing metal plate material, fire prevention alkali-free glass fiber layer withThe spacing of sound-absorbing metal plate material is 15-25mm;
Described keel are made up of galvanizing square tube, and the length of side of galvanizing square tube cross section is 35-45mm, and wall thickness is 1.5-2.5mm。
The area of sound-absorbing metal plate material comprises the area of sound-absorption hole, is the preperforative area of sound-absorbing metal plate material.
Punching rate of the prior art is no more than 20%, and easily occurs the problems such as distortion, and the application's punching rate can reach40%, sound-absorbing efficiency is had significantly and promote, and pass through the setting of the back side first flanging of sound-absorbing metal plate material, strengthenThe intensity of abatvoix, prevented from the distortion of abatvoix from having ensured the sound-absorbing efficiency in use procedure simultaneously; In prior artAbatvoix inner side post layer of non-woven fabric, not only inflammable, easily come off, and due to nonwoven color deeply also can affect attractive in appearance,The application selects fire prevention alkali-free glass fiber layer, is A1 level, and is provided with between fire prevention alkali-free glass fiber layer and sound-absorbing metal plate materialGap, so not only fire-resistant, and can further improve sound-absorbing effect and not affect the appearance at all. When use, metalSound-absorbing sheet material is fixed on keel by bolt and nut together with fire prevention alkali-free glass fiber layer.
The selection of above-mentioned keel structure and fixed form have further improved the stability of sound-absorbing wall; The choosing of alkali-free glass acoustical cottonWith the further sound-absorbing effect that improved.
Original abatvoix fixed form is that the extruding force that triangle draw-in groove relies on adjacent two boards to snap in same draw-in groove is fixed, if gotGo out one and will make other abatvoix chain-react cause large area to come off, lack security, and maintainable. This ShenSound-absorbing metal plate is please that individual is independently fixing, and adjacent two plates do not have inevitable contact on installation is fixing, can be as requiredAny any plate of dismounting, the dismounting of any plate all can not affect the stability of other plank, has flexibility and reliabilityCharacteristic, and in maintenance from now on, there is higher economy, therefore, although present techniques scheme has seemed letterSingle, but solved the very important technical problem always existing in prior art, and technique effect is very obvious, hasImmeasurable economic worth.
Preferably, above-mentioned sound-absorbing wall, also comprises metal fiber cloth, and metal fiber cloth is laid on interior wall and is positioned at interior wall and nothingBetween alkali glass acoustical cotton.
Above-mentioned metal fiber cloth the further sound-absorbing effect that improved is set, and extended the service life of sound-absorbing wall.
Preferably, sound-absorbing metal plate material is quadrangle, is equipped with vertical with sound-absorbing metal plate material on the four edges of sound-absorbing metal plate materialThe first flanging, wherein two relative limits of sound-absorbing metal plate material are provided with second flanging vertical with the first flanging, secondThe wrap direction of flanging is inside.
The wrap direction of above-mentioned inside finger two second flangings is relative, all points to sound-absorbing metal plate Cai center, the first flanging and goldBelong to sound-absorbing sheet material composition box body structure, above-mentioned inwardly also sensing in box body. Arranging of above-mentioned the second flanging further prevented goldBelong to the distortion of sound-absorbing sheet material, strengthened the intensity of sound-absorbing metal plate material.
Preferably, the wide of the second flanging is 20-30mm. The intensity of sound-absorbing metal plate can be ensured like this, sound-absorbing effect can be ensured againReally.
Preferably, sound-absorbing metal plate material is rectangle, and sound-absorbing metal plate material is thick is 1-3mm. To meet daily need.
More than sound-absorption hole has two rows, adjacent two row's sound-absorption hole are staggered. Can further improve like this sound-absorbing effect.
The thickness of fire prevention alkali-free glass fiber layer is 0.5-1.5mm. Can ensure like this fire resistance, can ensure sound-absorbing effect simultaneously.
The thickness of alkali-free glass acoustical cotton is 5-7cm. Make like this sound-absorbing effect and the intensity of sound-absorbing wall be guaranteed simultaneously.
The weld surface of keel and built-in fitting is provided with antirust coat.
The NM technology of the present invention is prior art.
The sound-absorbing metal plate punching rate of sound-absorbing wall of the present invention can reach more than 40%, prior art relatively, and sound-absorbing efficiency has had greatlyThe lifting of amplitude, structural stability is very good, without any distortion, long service life; It is good, no that metal is inhaled wall flameproof effectInflammable, sound-absorbing efficiency is high; Sound-absorbing metal plate installation fixed form is simple, has realized the monolithic of sound-absorbing metal plate and has fixed, anyThe dismounting of a sound-absorbing metal plate, all can not affect the fixing of other sound-absorbing metal plate; The high temperature resistant gentle stream of energy (wind-force)Impact humidity; Sound absorption qualities is good, fire prevention, moistureproof, indeformable, not modification, not mildew and rot, nonpoisonous and tasteless, extensivelyFor all kinds of industrial premises and indoor furred ceiling and the metopes that have noise reduction requirement, there is extremely strong decoration function simultaneously, be desirableSound-deadening and noise-reducing facility.
