Technical field
The utility model relates to a kind of sound-absorbing walls, in particular to sound-absorbing structure technical field.
Background technique
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 used in current existing sound-absorbing wall is inflammable, 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.
Utility model content
The purpose of this utility model is that in view of the above-mentioned drawbacks in the prior art, providing one kind can effectively absorb
Low, medium-high frequency noise sound-absorbing wall, and meet the requirement of fire-proof and damp-proof.
For achieving the above object, the utility model adopts the technical scheme that a kind of sound-absorbing wall, including metal bottom
Low-frequency sound-absorbing damping, sound-absorbing perforated panel and puigging, the sound-absorbing wall that plate, metal base plate inner wall are coated with further include sound insulation
Plate, Helmholtz's cavity puigging, the sound-absorbing wall by metal base plate, puigging, soundproof plate, 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 are with a thickness of 2mm to 3mm.
In preferred embodiments, it is by multilayer low frequency damping, soundproof plate and suction that the puigging, which is the puigging,
The complex sound insulation layer of sound cotton composition.
In preferred embodiments, the soundproof plate 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, utility model has the advantages that working as room noise incidence sound-absorbing wall, pass through porous metals
Panel enters inside sound-absorbing wall, by Helmholtz's cavity puigging, then to the double-deck soundproof plate, then arrives complex sound insulation layer, finally
Reach the metal base plate for being coated with low-frequency sound-absorbing damping, have good sound-absorbing effect to the noise of different frequency, due to bottom plate and
Panel is all made of metal, substantially increases waterproof fireproofing moisture protection.
Detailed description of the invention
Fig. 1 is sound-absorbing wall structural schematic diagram.
Fig. 2 is Helmholtz's cavity acoustical layer structure sectional view.
Specific embodiment
In conjunction with the preferred embodiment and its attached drawing is further unrestricted detailed to technical solutions of the utility model work
Explanation.
Sound-absorbing wall as shown in Figure 1, including metal base plate 1, puigging 3, soundproof plate 4,5 and of Helmholtz's cavity puigging
Sound-absorbing perforated panel 6, is arranged successively 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 55 is small, 54 space of cavity is big, and on resonant frequency, being open between 55 air and cavity 54, it is acute to generate
Sound 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, soundproof plate and acoustical cotton composition, and soundproof plate 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 biggish
Acoustic absorptivity, each medium-high frequency section sound is further isolated in puigging 3 and soundproof plate 4 at this time, in addition, soundproof plate 4 be heavy every
Soundboard can effectively reduce the vibration between two soundproof plates 4, to improve soundproof effect.
Metal base plate 1 is for steel plate and with a thickness of 2.0T, and surface carries out plastic-spraying processing, is coated in 1 inner wall of metal base plate
Low-frequency sound-absorbing damps with a thickness of 3mm, and metal base plate 1 is not easy to corrode, and low-frequency sound-absorbing damping 2 is able to suppress the vibration of metal base plate 1,
The effective noise for absorbing low-frequency range.
The utility model has the beneficial effects that when sound wave passes through inside the entrance sound-absorbing wall of sound-absorbing perforated panel 6, into multilayer excessively
The sound-absorbing of puigging finally reaches metal base plate 1, guarantees the reasonable distribution of each frequency range oise insulation factor of overall structure, different frequency
Sound wave can be effectively reduced, in addition, being filled with sound-absorbing material between each partiting sound member, enhance sound insulation property.
It should be pointed out that above-mentioned preferred embodiment is only to illustrate the technical ideas and features of the present invention, purpose
It is to enable those skilled in the art to understand the contents of the present invention and implement them accordingly, this reality can not be limited with this
With novel protection scope.All equivalent change or modifications according to made by the spirit of the present invention essence, should all cover in this reality
Within novel protection scope.
