Present invention is disclosed a kind of sound-absorbing walls, low-frequency sound-absorbing damping (2), sound-absorbing perforated panel (6) and the puigging (3) being coated with including metal base plate (1), metal base plate (1) inner wall, the sound-absorbing wall further includes sound panel (4), Helmholtz's cavity puigging (5), and the sound-absorbing wall is set gradually by metal base plate (1), puigging (3), sound panel (4), Helmholtz's cavity puigging (5) and sound-absorbing perforated panel (6).When room noise is incident on sound-absorbing wall, noise is entered by sound-absorbing perforated plate (6) inside wall, metal base plate (1) is finally reached by sound insulation layer by layer, low frequency and medium, high frequency noise can be effectively isolated, filling sucting sound material between partiting sound member, to enhance the frequency characteristic of building enclosure sound insulation.Since bottom plate and panel are metal, stable structure is unlikely to deform, and fire-proof and damp-proof effect is good.
Description
Technical field
The present invention relates to a kind of sound-absorbing walls, more particularly to sound-absorbing structure technical field.
Background technology
In order to control room internal unit generate noise to external influence, generally indoors install sound-absorbing wall or eliminate the noise dress
It sets, abatvoix is inflammable used in current existing sound-absorbing wall, and stability is poor, and sound-absorbing effect is also poor, and porous metals sound-absorbing wall is to height
Frequency noise has preferable sound-absorbing effect, general for middle low frequency noise effect.
Invention content
It is an object of the invention in view of the above-mentioned drawbacks in the prior art, provide one kind can effectively absorb it is low, in
The sound-absorbing wall of high frequency noise, and meet the requirement of fire-proof and damp-proof.
For achieving the above object, present invention employs following technical solutions：A kind of sound-absorbing wall, including metal base plate,
Low-frequency sound-absorbing damping, sound-absorbing perforated panel and puigging, the sound-absorbing wall that metal base plate inner wall is coated with further include sound panel, the last of the twelve Earthly Branches
Mu Huozi cavity puiggings, the sound-absorbing wall press metal base plate, puigging, sound panel, Helmholtz's cavity puigging and sound-absorbing
Perforated panel is set gradually.
In preferred embodiments, the metal base plate is steel plate, and the surface of steel plate does plastic-spraying processing.
In preferred embodiments, the low-frequency sound-absorbing damping coatings thickness is 2mm to 3m.
In preferred embodiments, it is by multilayer low frequency damping, sound panel and suction that the puigging, which is the puigging,
The complex sound insulation layer of sound cotton composition.
In preferred embodiments, the sound panel is the double-deck heavy structure.
In preferred embodiments, Helmholtz's cavity puigging is using the solid iron plate of steel construction as frame.
In preferred embodiments, sound-absorbing material is sticked outside Helmholtz's cavity puigging, inside filling is inhaled
Sound material.
In preferred embodiments, Helmholtz's cavity puigging includes being enclosed by the solid iron plate of the steel construction
Made of a plurality of cavities, the cavity offers the opening being connected with exterior space.
In preferred embodiments, filling sucting sound material between each partiting sound member.
Compared with the prior art, the advantage of the invention is that：When room noise incidence sound-absorbing wall, pass through porous metals panel
Into inside sound-absorbing wall, by Helmholtz's cavity puigging, then to the double-deck sound panel, then complex sound insulation layer is arrived, finally reached
It is coated with the metal base plate of low-frequency sound-absorbing damping, has good sound-absorbing effect to the noise of different frequency, due to bottom plate and panel
It is all made of metal, substantially increases waterproof fireproofing moisture protection.
Description of the drawings
Fig. 1 is sound-absorbing wall structural schematic diagram.
Fig. 2 is Helmholtz's cavity acoustical layer structure sectional view.
Specific implementation mode
Technical solution of the present invention is further non-limitingly described in detail below in conjunction with preferred embodiment and its attached drawing.
Sound-absorbing wall as shown in Figure 1, including metal base plate 1, puigging 3, sound panel 4,5 and of Helmholtz's cavity puigging
Sound-absorbing perforated panel 6, is arranged in order by said sequence, and 1 inner wall of metal base plate is coated with low-frequency sound-absorbing damping 2.
When sound wave is transmitted to sound-absorbing wall from sound generation source, it is transmitted to sound-absorbing perforated panel 6 first, sound wave is perforated face by sound-absorbing
The aperture of plate 6 enters Helmholtz's cavity puigging 5.
It is the cross-sectional view of the structure of Helmholtz's cavity puigging 5 as shown in Figure 2, the solid iron plate 51 of steel construction constitutes concave
54 structure of cavity, in internal 52 filling sucting sound materials, outside 53 sticks sound-absorbing material, when sound wave by Helmholtz's cavity every
When sound-absorbing layer 5, since opening is 55 small, 54 space of cavity is big, on resonant frequency, be open 55 air and cavity 54 between generate it is acute
Acoustic energy has been lost in strong resonant interaction, and the sound-absorbing material filled and sticked can further absorb remaining sound wave.
Puigging 3 is the complex sound insulation layer of 50mm thickness, by multilayer low frequency damping, sound panel and acoustical cotton composition, and sound panel 4
It is adjacent with puigging 3 for the double-layer structure of thickness 10mm, due to helmholtz resonance only on resonant frequency have it is larger
Acoustic absorptivity, at this time puigging 3 and sound panel 4 each medium-high frequency section sound is further isolated, in addition, sound panel 4 be heavy every
Soundboard can effectively reduce the vibration between two sound panels 4, to improve soundproof effect.
Metal base plate 1 is steel plate and thickness is 2.0T, and surface carries out plastic-spraying processing, is coated in 1 inner wall of metal base plate
It is 3mm that low-frequency sound-absorbing, which damps thickness, and metal base plate 1 is not easy corrosion, and low-frequency sound-absorbing damping 2 can inhibit the vibration of metal base plate 1,
The effective noise for absorbing low-frequency range.
The invention has the advantages that when sound wave is entered by sound-absorbing perforated panel 6 inside sound-absorbing wall, into multiple sound insulation excessively
The sound-absorbing of layer finally reaches metal base plate 1, ensures the reasonable distribution of each frequency range oise insulation factor of overall structure, the sound wave of different frequency
It can be effectively reduced, in addition, being filled with sound-absorbing material between each partiting sound member, enhance sound insulation property.
It is pointed out that the technical concepts and features of above-mentioned preferred embodiment only to illustrate the invention, its object is to
Those skilled in the art can understand the contents of the present invention and implements according to this, and the protection of the present invention can not be limited with this
Range.Any equivalent change or modification in accordance with the spirit of the invention should be covered by the protection scope of the present invention.
