Description
Technical field
The utility model relates to technical field of buildings, specially a kind of building sound-insulating structure.
Background technique
With the continuous improvement of society and living standards, various electronic products emerge one after another, and people build house class
Sound isolation requirement is also higher and higher.Currently, existing construction wall structure is main still by concrete wall, bonding mortar and block
Block is constituted, and can not meet the requirement of people's daily life in the processing of sound insulation, especially upstairs there is resident, from upstairs
Noise is unable to get certain elimination.
Utility model content
For above-mentioned technical deficiency, the purpose of the utility model is to provide a kind of building sound-insulating structures, for day
Card carries out sound insulation, reduces the noise that upstairs resident generates resident downstairs.
In order to solve the above technical problems, the utility model adopts the following technical solution:
The utility model provides a kind of building sound-insulating structure, including successively fit together abatvoix, nonwoven sound-absorbing cloth,
Glass fibre acoustical cotton, heat-insulated masking foil and plasterboard offer several equally distributed speaker holes on the abatvoix,
Two adjacent speaker holes are tangent, and the internal diameter of these speaker holes is gradually reduced along the direction close to the plasterboard, institute
The bottom hole for stating speaker hole offers the through-hole communicated with the speaker hole, and first acoustic damping mesh is fixedly installed in the through-hole
With second acoustic damping mesh, first acoustic damping mesh setting parallel with second acoustic damping mesh, first acoustic damping mesh and institute
The mesh for stating the second acoustic damping mesh is square, the spacing of first acoustic damping mesh and second acoustic damping mesh 1mm~2mm it
Between, the area of the mesh of first acoustic damping mesh is greater than the area of the mesh of second acoustic damping mesh, second acoustic damping mesh position
Between the nonwoven acoustical cotton and first acoustic damping mesh.
Preferably, the depth of the through-hole is not more than 4mm.
Preferably, the thickness of the glass fibre acoustical cotton is not less than 15mm.
The utility model has the beneficial effects that: the principle that the sound-insulating structure is reversely amplified using loudspeaker, by speaker hole
Being flared direction reduces the propagation of sound towards sound source, and then reversely, while acoustic damping mesh is further arranged in the bottom hole of speaker hole, benefit
Sound wave is further consumed with the mesh of acoustic damping mesh；Furthermore nonwoven sound-absorbing cloth, glass fibre acoustical cotton and heat-insulated masking foil
Further consumption sound wave, is weakened noise upstairs, and then reduce to the noise generated downstairs.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor
Under, it is also possible to obtain other drawings based on these drawings.

Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
As shown in Figures 1 to 4, a kind of building sound-insulating structure, including abatvoix 1, the nonwoven sound-absorbing successively to fit together
Cloth 2, glass fibre acoustical cotton 3, heat-insulated masking foil 4 and plasterboard 5 offer several on the abatvoix 1 and are uniformly distributed
Speaker hole 11, two adjacent speaker holes 11 are tangent, the internal diameters of these speaker holes 11 is along close to the plasterboard 5
Direction is gradually reduced, and the bottom hole of the speaker hole 11 offers the through-hole communicated with the speaker hole 11, is fixed in the through-hole
It is provided with first acoustic damping mesh 12 and second acoustic damping mesh 13, first acoustic damping mesh 12 and 13 phase of the second acoustic damping mesh
It is arranged in parallel, the mesh of first acoustic damping mesh 12 and second acoustic damping mesh 13 is square, first acoustic damping mesh 12
For spacing with second acoustic damping mesh 13 between 1mm~2mm, the area of the mesh of first acoustic damping mesh 12 is greater than described the
The area of the mesh of two acoustic damping meshes 13, second acoustic damping mesh 13 are located at the nonwoven acoustical cotton 2 and first acoustic damping mesh 12
Between, using the first acoustic damping mesh 12 mesh area to the second acoustic damping mesh 13 mesh area reduction, and then to sound wave generate
Consumption gradually.
Further, the depth of the through-hole is not more than 4mm.
Further, the thickness of the glass fibre acoustical cotton 3 is not less than 15mm.
Wherein nonwoven sound-absorbing cloth 2, glass fibre acoustical cotton 3, heat-insulated masking foil 4 are existing product, and there is sale in market,
The application does not do excessive narration, it is further noted that understanding structure to show, what the attached drawing in the application was shown is
A portion of the sound-insulating structure.
In use, 5 plate of gypsum is constructed according to conventional form of construction work, it is installed in roof, 11 direction of speaker hole
Roof reduces the propagation of sound using speaker hole 11.
In noise reduction field, wrong understanding first is that think shaggy material have sound absorbing performance, actually this is not so, such as
Stucco, surface relief stone just substantially do not have acoustical absorptivity.Wrong understanding second is that think that material internal has a large amount of
The material of hole, such as polyphenyl, polyethylene, closed-cell polyurethane, have good sound absorbing performance, in fact, these materials due to
Inner void does not have connectivity, and sound wave cannot go deep into material internal vibration friction, therefore acoustic absorptivity very little；The utility model is anti-
To the principle to amplify using loudspeaker, by the flaring direction of speaker hole towards sound source, and then the propagation of sound reversely is reduced, and be arranged
Through-hole so that speaker hole is communicated with nonwoven sound-absorbing cloth, glass fibre acoustical cotton, and then realizes the connectivity of the inside configuration,
Sound wave is goed deep into nonwoven sound-absorbing cloth and glass fibre acoustical cotton by speaker hole, and then reduction sound wave gradually, most
The sound wave being closely lowered is carrying out reflection a part, while heat reflection one that sound wave loss is generated by heat-insulated masking foil
Point, it is final to reduce upstairs to the noise generated downstairs.
Obviously, it is practical without departing from this can to carry out various modification and variations to the utility model by those skilled in the art
Novel spirit and scope.If in this way, these modifications and variations of the present invention belong to the utility model claims and
Within the scope of its equivalent technologies, then the utility model is also intended to include these modifications and variations.
