Description
Technical field
The utility model is related to a kind of decoration painting, especially can absorption of noise indoor sound absorption decoration painting.
Background technology
With China's economy, the development of science and technology, the electromechanical equipment that civil buildings are configured is all more and more so that noise source
It is on the increase.Meanwhile, with the raising of economic level, people are to improving the requirement including the living environment quality including acoustic environment
Improve constantly, the noise tolerance of people also constantly declines.
Sound absorption is a kind of measure for being effectively blocked and reducing acoustic propagation, is a kind of most basic with the most frequently used measure.Make
With that can absorb the wall of the material or structural ornament of acoustic energy in computer room, the noise that can be sent with absorption of noise source is mapped to above
Part acoustic energy, weaken reflected sound, simply direct sound wave and the reverberation sound that has weakened that recipient at this time hears make overall noise
Level is reduced.Sqouynd absorption lowering noise mechanism, the sound that sound source sends can all reflect when running into metope, ceiling, terrace and other objects
Phenomenon.Room sound field is generally all to be superimposed structure by the direct sound wave of sound source direct radiation and by the reverberation sound that indoor each surface is reflected
Into.At sound source, direct sound wave is dominant；Then it is based on reverberation reflected sound at away from sound source.Sqouynd absorption lowering noise is mainly logical
The indoor average sound absorption coefficient of raising is crossed, weakens the energy of reflected sound, the purpose of room noise is reduced to reach.Its effect is depended on
Distance of the original sound absorption condition in the acoustical behavior of sound-absorbing material used, absorption area, room and receiving point and sound source etc. because
Element.
But, currently used sound-absorbing material is often sound-absorbing porous material, thus produces the problem hung and stay dust.Institute
It is mostly hard slippery surface layer with ornament materials under construction, the deficiency of absorption area causes reverberation serious.
The microperforated panel soundabsorbing construction initiated by Acoustics In China authority's Ma Dayou, is exactly the base in sound absorbent perforated structure
On plinth, the aperture of perforation is narrowed down to below millimeter, shape microperforated panel soundabsorbing construction can increase hole acoustic resistance in itself, without
Additional porous material can just obtain satisfied acoustic absorptivity.For broadening frequency range and raising acoustically effective, can also use
Different punching rates, aperture and multilayer microperforated panel soundabsorbing construction.
And it is current, various buildings are often using decoration painting as important decorative content.Part public building even also has big
The decoration mural painting of area.
The content of the invention
The purpose of this utility model is the decorative effect of the advantage and decoration painting for combining microperforated panel soundabsorbing construction, there is provided
A kind of sound absorption decoration painting with acoustically effective.To improve indoor absorption area, indoor noise reverberation is reduced.
The utility model solves the technical scheme that its technical problem used：A kind of indoor sound absorption decoration painting, including just
The Decorative frame of face sound absorption decorative picture, installation frame structure, back side sound insulationg board and surrounding, installation frame structure includes steel square tube
Framework, flase floor, rear microperforated panel and overall steel load-carrying construction.Steel square tube frame is arranged on overall steel load-carrying construction front, inhales
Sound decorative picture is arranged on steel square tube frame front using high-strength double-face glue, and flase floor is arranged in steel square tube frame, with steel
Square tube frame front is concordant, and microperforated panel is arranged on the back side of steel square tube frame, and sound insulationg board is carried on the back installed in overall steel load-carrying construction
Face.During the large-scale sound absorption decoration painting collectively constituted by multi-disc decorative picture, in order to ensure the seam of multi-disc sound absorption decorative picture
It is smooth, installed using high-strength double-face glue in steel square tube frame front between sound absorption decorative picture.By by with steel square tube frame
Front flush grid plate, the sound absorption decorative picture back side is reliable Nian Jie using nail-free glue and flase floor front, to ensure that multi-disc absorbs sound
The overall leveling of decorative picture.Meanwhile, sound absorption decorative picture forms the resonating cativty of closing with flase floor, microperforated panel, favorably
In the raising for ensureing acoustic absorptivity.Built-in microperforated panel by air brushing, installation strength, flatness because not influenceed, including perforation
Aperture, thickness, material can have multiple choices.
Described sound absorption decorative picture system is input into spray drawing machine according to selected picture after the scanning of too high pixel, finishing
Air brushing is formed on micropunch aluminium sheet；Or directly drawn in micropunch aluminium sheet plate face using aqueous pigment, picture includes that photography is made
Product, drawing, calligraphy, decoration figure etc..Described micropunch aluminium sheet is 0.5~2mm by thickness, the aperture of perforation for 0.5~
0.8mm, punching rate is made up of 1~3% aluminium sheet.Lightweight, the good weatherability of aluminium sheet.Using spray drawing machine air brushing, coating is thin, no
The generation of the micropore for being 0.5~0.8mm can be produced to aperture to block.Because the aperture perforated is 0.5~0.8mm, there is picture
Sound absorption decorative picture, substantially discover the presence of micropore.The thickness of slab of micropunch aluminium sheet is adjusted according to the specification of picture, micropunch
The frequency of the room noise that aperture, the punching rate of the perforation of aluminium sheet absorb according to needed for determines.In low-frequency range, smaller punching rate
Sound absorbing capabilities are good, but in lower frequency range, larger punching rate sound absorbing capabilities are good.The thickness of cavity, resonance after increasing perforated plate
The peak value of sound absorption is moved to low frequency, and the thickness of cavity is doubled, and the peak value of sound absorption moves 1/2 octave to low frequency, after reduction
The thickness of cavity, the peak value of resonance sound-absorbing is to high-frequency mobile.
Described rear microperforated panel is tied up to by aperture that thickness is 0.1~0.5mm, perforation as 0.2~0.8mm, punching rate
Sheet material by 1~5% is made.Described absorb sound decorative picture and the distance >=40mm of rear microperforated panel, rear microperforated panel and sound insulation
Distance >=the 50mm of plate.It is in order to extend the sound absorption frequency range of porous plate acoustic adsorption device, using double-deck microperforated panel composite construction, two
Unequal distance cavity is left between layer microperforated panel, so, it just has 2 resonant frequencies, so as to greatly expand acoustic frequency bandwidth
Degree.Improve noise reduction coefficient NRE.
Described sound absorption decorative picture is arranged on steel square tube frame front, the sound absorption decorative picture back of the body using high-strength double-face glue
Face is reliable Nian Jie using nail-free glue and flase floor front, and rear microperforated panel is gluing using high-strength double-face with the steel square tube frame back side
Connect.
When described sound absorption decoration painting is made up of monolithic sound absorption decorative picture, sound absorption decorative picture uses high-strength double-face glue
Installed in frame structure front, in installation frame structured rear surface, Decorative frame is in installation frame structure surrounding for sound insulationg board；Sound absorption dress
