Description
Technical field
The utility model is related to a kind of close spelling embedded and hung suspension rod sound-absorbing furred ceiling of rectangle.
Background technology
The penetration hole diameter of common perforated plate is controlled to below 1mm, microperforated panel is formed.Now, microperforated panel
Inherently there is enough acoustic resistances, while having sufficiently low mass reactance, broadband sound absorber is formed, without adding
Any porous material.With the development and raising of material and perforation process technology, and wideband, efficient, cleaning, the sound absorption of environmental protection
Feature, microperforated panel soundabsorbing construction is widely used in metope and the top surface finishing in numerous places.
Microperforated panel is considered as a large amount of micro-pipes（Micropunch）Parallel connection, each micropunch is a very thin short tube,
When pitch of holes is more much larger than aperture, it will be assumed that the characteristic in each hole is independent of each other, the acoustic impedance of microperforated panel is simply equal to single hole
Acoustic impedance divided by hole quantity.When sound wave is propagated in pipe, it is considered to the influence of viscosity, particle the shaking vertically on tube wall
Dynamic speed is zero, and vibration velocity on center shaft is maximum, there is velocity step ladder along radial direction in pipe.On the other hand between hole
Away from it is more much smaller than wavelength when, reflection of the plate face to sound wave can also ignore between hole.
" the accurate theoretical and design of porous plate acoustic adsorption device " that Ma Dayou academician 1997 delivers in acoustic journal and
" potentiality of porous plate acoustic adsorption device " academic article for being delivered in Acoustical Society of America's magazine for 1998, it is indicated that by penetration hole diameter
Further reduce, the broader sound absorber of sound sucting band can be obtained.By micropunch bring into the ultramicropore epoch can show its suction
Receive the frightened human potential of performance.
Micropunch abatvoix in the market can only accomplish 0.7mm aperture, and hole is the straight hole perpendicular to plate face, directly
Hole effect during sound-absorbing is poor, and sound absorbing paper is enclosed at the back side of this micropunch abatvoix and can be only achieved preferable sound-absorbing effect
Really.
Traditional ceiling structure, which exists, installs inconvenience, the good defect of sound-absorbing effect.
The content of the invention

Keel, the lateral keel includes being vertically provided with multiple hooks along its length, the transverse direction in keel main body, keel main body
Rectangle embedded and hung abatvoix is connected with keel, rectangle embedded and hung abatvoix is formed by the bending of micropunch abatvoix, rectangle
Embedded and hung abatvoix includes lower crosspiece, and the left and right ends of lower crosspiece have been folded upward at the perpendicular section in a height identical left side and right perpendicular respectively
Section, the upper end of the perpendicular section in a left side is bent with upper crosspiece to the left, and lower section is bent with left hook, the upper end of the perpendicular section in the right side to the left end of upper crosspiece to the left
Right hook is bent with to the left, and the left hook and right hook of rectangle embedded and hung abatvoix are placed on the hook of lateral keel, be located at
The upper crosspiece of adjacent two pieces of rectangles embedded and hung abatvoix on same hook be overlapped on right hook and by it is left link up with into
Row locking, section is erected on a left side for adjacent two pieces of rectangles embedded and hung abatvoix and right perpendicular section is close to, and polylith rectangle embedded and hung abatvoix exists
Lateral keel forms the close spelling structure in surface after hanging, the micropunch abatvoix includes being provided with plate body, the plate body uniformly
The micropunch of arrangement, it is characterised in that the micropunch is diagonally disposed, micropunch the back side formed stop part, stop part with it is micro-
Gap is left between perforation, gap combines to form sound channel with micropunch.
Angle of the sound channel in the back side exit of plate body and plate body is 0-45 degree.
The aperture of micropunch is 0.1-0.2mm, and the pitch-row of micropunch is 2.2mm.
The plate body is aluminium alloy or galvanized steel.
Plate body thickness is 0.8-1mm.
The surface of the plate body is provided with decorative layer.
Decorative layer is the pre- roller coat of polyester, polyester spraying, electrostatic powder coating, coated by high-molecular film or anode oxide film.
The vertical cross-section of sound channel is isosceles triangle, isosceles trapezoid or semicircle.
Cross spacing piece and vertical spacing piece are additionally provided with keel main body, the cross spacing piece of lateral keel is to rectangle
It is spacing that section progress is erected on a left side for embedded and hung abatvoix.
Compared with prior art, the beneficial effects of the utility model are：
The close embedded and hung suspension rod sound-absorbing furred ceiling of spelling of the utility model rectangle is because the micropunch of abatvoix is diagonally disposed, and sound wave exists
The portion of being blocked is stopped during being transmitted in sound channel, and intensity is reduced by multiple reflections, finally from close to plate body
In the gap at the back side out, some can also carry out absorption reflection by the plate body back side, so as to preferably improve sound-absorbing effect.
Therefore the close embedded and hung suspension rod sound-absorbing furred ceiling of spelling of the utility model rectangle has easy for installation, the good advantage of sound-absorbing effect.
