Description
Technical field
The present invention relates to sound insulation of wall noise reduction technology field, and in particular to a kind of sound insulation and noise reducing wall.
Background technology
There are a variety of dynamic equipment in industrial enterprise's factory building, the noise such as mechanical oscillation, pneumatic noise not only influences to operate employee's
Physical and mental health, noise pollution that What is more can influence the social environment beyond factory circle.Therefore, industrial enterprise's factory building is built, transformed
Shi Caiyong sound insulation and noise reducing walls are the essential measures of governing noise pollution.
In current noise abatement engineering following form is used for sound-proof wall majority：
1st, it is general to be assembled using building block brick for the less demanding wall of oise insulation factor, construction weight is generally 250~
500kg/m2, construction weight is excessive；Or using the form of " panel+sound-absorbing material+perforated plate ", it belongs to lightweight construction, but
It is the surface density that this kind of Sound Insulation for Structure amount depends on panel, panel is typically made using steel plate, cement plate etc., and increase surface density can
To improve oise insulation factor, but construction weight is also improved, perforated plate is typically made using galvanized sheet or aluminium sheet.
2nd, require that higher wall uses multi-layer compound structure for oise insulation factor, typically there are several structure sheafs：Insulate against sound backboard
(majority is using middle-high density 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 work on the spot amount is big.Because by making, execution conditions are limited, cause to install, 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 serve soundproof effect, but relatively 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 more bulky shortcoming of above-mentioned wall, but
Easily come off after being this sound arrester time length, and be difficult trimming after coming off, so as to lose noise control function.
The Chinese patent literature of Application No. 201220519643.3 discloses a kind of Acoustic barrier plate, including the flexible fibre of internal layer
Layer, central frame material layer and outer layer sheet metal layer are tieed up, the Acoustic barrier plate also includes sound-absorbing material layer, and the sound-absorbing material 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
It is adhesively fixed between plate, wire netting or grid plastics, each layer.It is due to not to be although this structure is simpler, easy to assembly
Hollow, its material is still laid particular stress on, and is difficult construction.
The content of the invention
The problem of for presently, there are, the present invention provides a kind of new sound insulation and noise reducing wall, and the wall can efficiently be inhaled
Sound noise reduction, the quadratic noise that can be prevented wall from shaking and trigger, wall surface density is low, and light weight need not be adopted during construction
Assistance construction is carried out with crane or other crane gears, construction cost is reduced.
To achieve the above object, the present invention is adopted the following technical scheme that：
A kind of sound insulation and noise reducing wall, the wall includes porous honeycomb, sound insulation chamber and the sound insulation chamber of ecto-entad
Uniform honeycomb hole in wall, the porous honeycomb, and the percent opening of porous honeycomb is 1-60%.
Further, the honeycomb hole is circular hole or square hole, and the aperture of the circular hole is 1-8mm, and the length of side of square hole is 2-
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, need not be carried out during construction using crane or other crane gears
Construction is assisted, artificial construction can be directly carried out, reduce labor intensity, machinery expenses, while being adapted to the construction of small space.
Wherein, the porous honeycomb and sound insulation chamber wall are made by the composition of following percentage by weight：Cement 20~
40%th, sandstone 20~40%, coal ash powder 10~20%, clinker 10~30%, adhesive 1~4%.
In particular to the adhesive is resinae, such as epoxy resin, polyvinyl acetate, phenolic resin.
The inventive method has the following advantages that：
Honeycomb ceramics has good sound absorbing capabilities in itself, and this structure is combined by 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 capabilities are more improved.Simultaneously because inside configuration
There are a large amount of gaps and a large amount of sound-absorbing materials, can prevent that the vibrations of 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, sound-proof wall body of the present invention can using customizing production, every product size in 1000mm × 2500mm according to
Depending on demand.
Also, sound-proof wall body of the present invention is lighting wall, and surface density is 20-60kg/m2, need not use and hang during construction
Car or other crane gears carry out assistance construction, can directly carry out artificial construction, reduce labor intensity, machinery expenses,
It is adapted to the construction of small space simultaneously.
