Description
Technical field
This utility model relates to a kind of micropore sound absorption and insulation composite plate structure, belongs to composite plate technical field.
Background technology
Due to progress and the development of science and technology of society, noise problem is more and more prominent, has had a strong impact on
The study of the mankind, work, live and physically and mentally healthy, the most how to effectively reduce sound pollution, more
More being subject to people's attention, national governments have also put into bigger manpower and materials and have carried out noise abatement.Existing
It is poor that some composite plates are usually present soundproof effect, and sound pollution is big, intensity and poor rigidity.
Summary of the invention
The technical problems to be solved in the utility model is: provide a kind of micropore sound absorption and insulation composite plate structure,
Soundproof effect is good, and sound pollution is little, and support strength and rigidity are high, to solve to ask present in prior art
Topic.
The technical scheme that this utility model is taked is: a kind of micropore sound absorption and insulation composite plate structure, including wall
Plate one and wallboard two, be provided with honeycomb interlayer, on described honeycomb interlayer between described wallboard one and wallboard two
It is provided with the minimum one piece of microperforated panel being parallel to wallboard one, described microperforated panel is provided with micropore.
Preferably, above-mentioned micro-pore diameter is 2～3mm.
Preferably, above-mentioned wallboard one and wallboard two material are steel plate.
Preferably, the above-mentioned microperforated panel thickness honeycomb interlayer thickness less than 1/10th.
When micropore sound insulation operation principle is the aperture that the sound sent when sound source is delivered to microperforated panel, aperture
The wall sound to transmitting produces damping and rubbing action, makes the acoustic energy transmitted be decayed, and energy reduces,
Simultaneously because honeycomb interlayer is divided into the sub-cavity of multiple closing, makes to enter into the heat of structure and sound wave is subject to
Greatly hindering, sound wave can also effectively be reflected by cavity wall.
The beneficial effects of the utility model: compared with prior art, this utility model uses minimum one piece
Microperforated panel with micropore is arranged on honeycomb sandwich construction, it is possible to significantly play soundproof effect, reduces ring
The sound pollution in border, and honeycomb sandwich construction has heat insulation, the effect of sound insulation, especially makes an uproar low frequency
Sound has the structure of good insulating effect, microperforated panel and honeycomb interlayer, and the soundproof effect played is more preferable,
Efficiently solve that soundproof effect present in prior art is poor, sound pollution serious and rigidity and intensity low
Problem, this utility model also has simple in construction, low-cost feature.
Accompanying drawing explanation
Fig. 1 is perspective view of the present utility model；
Fig. 2 is front-view schematic diagram of the present utility model；
Fig. 3 is sectional structure schematic diagram A-A in Fig. 2.
In figure: 1-wallboard one, 2-wallboard two, 3-honeycomb interlayer, 4-microperforated panel, 5-micropore.
Detailed description of the invention
Below in conjunction with the accompanying drawings and utility model is described further by specific embodiment.
As shown in FIG. 1 to 3, a kind of micropore sound absorption and insulation composite plate structure, the wallboard made including steel plate
One 1 and wallboard 22, it is provided with honeycomb interlayer 3, honeycomb interlayer between described wallboard 1 and wallboard 22
It is provided with the minimum one piece of microperforated panel 4 being parallel to wallboard 1 on 3, described microperforated panel 4 is provided with
Logical micropore 5, micropore 5 a diameter of 2～3mm, microperforated panel 4 thickness honeycomb folder less than 1/10th
Layer 3 thickness, the through hole of honeycomb interlayer 3 uses hexagonal hole.
Micropore honeycomb sandwich construction of the present utility model is a kind of that microperforated panel is comprehensive with honeycomb sandwich construction
The compound sound absorption and insulation structure of one, can effectively reduce sound pollution, protects environment.Its work is former
When reason is the aperture that the sound sent when sound source is delivered to microperforated panel, the wall sound to transmitting in aperture produces
Damping and rubbing action, make the acoustic energy transmitted be decayed, and energy reduces, simultaneously because honeycomb sandwich layer divides
It is divided into the sub-cavity of multiple closing, makes to enter into the heat of structure and sound wave is greatly hindered, cavity wall
Sound wave effectively can also be reflected, thus honeycomb sandwich construction has heat insulation, the effect of sound insulation,
The especially noise to low frequency has good insulating effect.From amechanical angle, due to honeycomb sandwich layer
Highly being far longer than flaggy thickness, the moment of inertia of structural profile becomes biquadratic to increase therewith, and panel has folder
Sandwich layer supports and is not likely to produce unstability and buckling deformation.If this utility model can be applied to real life,
Will bring good social effect, this utility model design is simple, and low cost can be promoted.
This utility model design simply has the advantage that
(1) light weight and rigidity are big, and weight loss effect is the most prominent, are a kind of efficient light structures materials
Material, the relatively thin material that micropore honeycomb interlayer composite construction panel can select, laminboard layer mostly is cavity in addition
Form and be thin therefore light weight.
(2) malformation is little, owing to the height of light sandwich layer is much larger than upper and lower panel layer thickness, structure
The moment of inertia of section becomes biquadratic to increase therewith, and panel has laminboard layer support to be not likely to produce unstability and warpage
Deformation.
(3) sound absorption efficiency is high, owing to micropore honeycomb interlayer composite construction aperture is small, and inner air medium
Flow resistance is bigger so that the sound wave entering structure occurs friction repeatedly to disappear with air dielectric in the confined space
Consume acoustic energy, can be with the sound absorption sensitizing range of control structure, this structure by the height of air layer after regulation
The effect producing the noise of medium and low frequency is especially pronounced.
(4) sound insulation property is high, owing to honeycomb sandwich layer is divided into the sub-cavity of multiple closing, makes to enter into structure
Heat and sound wave greatly hindered, sound wave can also effectively be reflected by cavity wall, thus
Honeycomb sandwich construction has heat insulation, the effect of sound insulation, the especially noise to low frequency and has good isolation work
With.
The above, detailed description of the invention the most of the present utility model, but protection domain of the present utility model
It is not limited thereto, the technology model that any those familiar with the art discloses at this utility model
In enclosing, change can be readily occurred in or replace, all should contain within protection domain of the present utility model, because of
This, protection domain of the present utility model should be as the criterion with described scope of the claims.
