Description
Technical field
The utility model is related to wall acoustic noise reduction technical fields, and in particular to a kind of sound insulation and noise reducing wall.
Background technology
There are many dynamic equipment in industrial enterprise's workshop, the noises such as mechanical oscillation, pneumatic noise not only influence to operate employee's
Physical and mental health, noise pollution that What is more can influence the social environment beyond factory circle.Therefore, the construction of industrial enterprise's workshop, transformation
Shi Caiyong sound insulation and noise reducing walls are the essential measures of governing noise pollution.
At present following form is used for sound-proof wall is most in noise abatement engineering：
1st, for oise insulation factor wall of less demanding, generally being assembled using building block brick, construction weight is generally 250~
500kg/m2, construction weight is excessive；Or the form using " panel+sound-absorbing material+perforated plate ", belong to lightweight construction, but
It is the surface density that this kind of Sound Insulation for Structure amount depends on panel, for panel generally using making such as steel plate, cement plates, increasing surface density can
To improve oise insulation factor, but construction weight is also improved, perforated plate is generally made of galvanized sheet or aluminium sheet.
2nd, generally there are several structure sheafs using multi-layer compound structure for the more demanding wall of oise insulation factor：Insulate against sound backboard
(majority is using middle-high densities materials such as cement plate, fiberboards), damping layer, sound-absorbing material and perforated plate, according to noise frequency, make an uproar
Volume determines the denoising structure number of plies, combining form.And form of construction work is then the splicing of each structure sheaf scene at present, each layer is taken up in order of priority
Construction, construction technology is complicated, and site workload is big.Due to be subject to make, execution conditions are limited, cause installation, it is assembled by mistake
It is poor big, it is difficult to ensure construction quality.
3rd, sound-proof wall body of the prior art is generally overall structure, i.e., in wall central filler acoustic material, so every
Sound wall is exactly solid on the whole, although soundproof effect is played, but it is heavier, and waste of materials.
The Chinese patent literature of Application No. 201310419258.0 discloses a kind of sound-proof wall body, the sound-proof wall body bag
Cavity is included, sound arrester is installed in the cavity wall of cavity, although this device overcomes the shortcomings that above-mentioned wall is heavier, but
It is easily to come off after having grown this sound arrester time, and is not easy to rebuild after coming off, so as to loses noise control function.
The Chinese patent literature of Application No. 201220519643.3 discloses a kind of Acoustic barrier plate, flexible fine including internal layer
Layer is tieed up, central frame material layer and outer layer sheet metal layer, the Acoustic barrier plate further include sound-absorbing material layer, which is rock
Cotton；The internal layer flexible fiber layer is barrier sheet, and the central frame material layer is plasterboard, and the outer layer sheet metal layer is perforation
Plate, metal mesh or grid plastics are adhesively fixed between each layer.Although this structure is simpler, easy to assembly, due to not being
Hollow, material is still laid particular stress on, and is not easy to construct.
Utility model content
For presently, there are the problem of, the utility model provides a kind of new sound insulation and noise reducing wall, which can be high
Sqouynd absorption lowering noise is imitated, the quadratic noise that can be prevented wall from shaking and trigger, the wall surface density is low, light weight, and when construction is not required to
Crane or other lifting equipments to be used to carry out assistance construction, reduce construction cost.
To achieve the above object, the utility model adopts the following technical solution：
A kind of sound insulation and noise reducing wall, the wall include porous honeycomb, sound insulation chamber and the sound insulation chamber of ecto-entad

8cm。
Further, arrangement mode of the honeycomb hole in porous honeycomb is rectangular array formula or triangle battle array
Column.
Preferably, the sound insulation chamber thickness is 50-100mm, the sound insulation chamber wall thickness 10-50mm, the sound insulation drop
Make an uproar thickness of wall body 70-300mm.
The surface density of the wall is 20-60kg/m2, crane or other lifting equipments need not be used to carry out during construction
Construction is assisted, can directly carry out artificial construction, labor intensity, machinery expenses is reduced, while is suitble to the construction of small space.
Wherein, the porous honeycomb and sound insulation chamber wall are made of the ingredient of following weight percent：Cement 20~
40%th, sandstone 20~40%, coal ash powder 10~20%, clinker 10~30%, adhesive 1~4%.
It is resinae in particular to, the adhesive, such as epoxy resin, polyvinyl acetate, phenolic resin.
The utility model method has the following advantages that：
Honeycomb ceramics has good sound absorbing performance in itself, and this structure is composed of multiple material, and structure is of a relatively loose,
Internal after shaping structures to have a large amount of gaps and the combination of a large amount of sound-absorbing materials, sound absorbing performance more improves.Simultaneously because inside configuration
There are a large amount of gaps and a large amount of sound-absorbing materials, the vibrations that can prevent sound insulating structure are transaudient.And what the air layer for the chamber that insulates against sound had
" spring effect " improves total oise insulation factor of wall.
In addition, customization production can be used in the utility model sound-proof wall body, every product size is in 1000mm × 2500mm
Inside it is in accordance with demand.
Also, the utility model sound-proof wall body be lighting wall, surface density 20-60kg/m2, when construction need not adopt
Assistance construction is carried out with crane or other lifting equipments, artificial construction can be directly carried out, reduce labor intensity, machinery cost
With, while it is suitble to the construction of small space.
