Description
Technical field
This utility model is related to room acoustics environmental Kuznets Curves field, especially a kind of modular microfluidic perforated acoustic board.
【Background technology】
Indoors noise transmission carried out sound absorption process by sound in the face of it, be one of noise control common method.Work as room
What interior sound source sent sound runs into and can reflect during the body surfaces such as metope, roof, and the sound that at this moment people are heard removes
Also have, outside direct sound wave, the reflected sound returned through these surface multiple reflections, if indoors metope or roof install sound-absorbing material or
Suspended absorber, a part is fallen in indoor reflection sound absorption, and indoor noise can obtain a certain degree of reduction.Conventional porous
Inorfil class sound-absorbing material includes glass cotton, mineral wool and rock wool etc., and microperforated panel soundabsorbing construction then can obtain and inhale than other
The more permanent service life of acoustic form, and because being not filled with any sound-absorbing material, not existing and two are produced to indoor environment
The problem of secondary pollution.
Existing metallic panel absorber is actually metal protection slab, does not have sound absorbing capabilities, its sound absorption mainly according to
Sound-absorbing material by the filling of its back side.
Therefore, for avoiding above-mentioned technical problem, it is necessory to provide one kind to have structure improved sound absorption, existing to overcome
Described defect in technology.
【Utility model content】
In order to overcome above-mentioned weak point present in prior art, the purpose of this utility model is to provide a kind of module
Change Micropunch Acoustic Board.
In order to reach above-mentioned purpose, this utility model adopts following concrete technical scheme：Modular microfluidic perforated acoustic board,
Including metal micropunch outside plate, metal micropunch inner panel, metal micropunch backboard and module mounting plate, outside described metal micropunch
The both sides of plate and metal micropunch inner panel all at right angles fold has outside plate folded edge and inner panel folded edge, metal micropunch outside plate
All U-shaped structure is become, described metal micropunch inner panel is arranged on shape in metal micropunch outside plate after folding with metal micropunch inner panel
Become cavity one, described outside plate folded edge and inner panel folded edge fit tightly, described metal micropunch backboard arranges the inner panel of both sides
Form cavity two, described module mounting plate is arranged on the both sides of metal micropunch backboard between folded edge.
Further, one end outward bending of module mounting plate described in the utility model has kink, and its other end is even
It is connected on metal micropunch backboard.
Further, metal micropunch outside plate described in the utility model, metal micropunch inner panel and metal micropunch backboard
On be provided with a plurality of micropores.
This utility model advantage compared with prior art is：Due to being provided with above structure, this utility model can be effective
Shorten the field erected time, due to being the modular absorbing wall and suspended ceiling device made in advance, can avoid because existing
Field makes and is limited by construction environment.This acoustic board is not filled with any sound-absorbing material, and can avoid the fiber of sound-absorbing material
Leakage problem, can be applied to the high place of purity requirements and the place of other particular/special requirement, such as superhigh temperature, ultralow temperature etc.
The sqouynd absorption lowering noise in place.
【Brief description】
Fig. 1 is structural representation of the present utility model；
The utility model is described in further detail below in conjunction with the accompanying drawings.
【Specific embodiment】
Understandable for enabling above-mentioned purpose of the present utility model, feature and advantage to become apparent from, below in conjunction with the accompanying drawings to this
The specific embodiment of utility model is described in detail.
Elaborate detail in order to fully understand this utility model in the following description.But this utility model can
To be implemented different from alternate manner described here with multiple, those skilled in the art can be without prejudice to this utility model intension
In the case of do similar popularization.Therefore this utility model is not embodied as being limited by following public.
Refer to shown in Figure of description 1, this utility model be modular microfluidic perforated acoustic board, including metal micropunch outside
Plate 1, metal micropunch inner panel 2, metal micropunch backboard 3 and module mounting plate 4, in metal micropunch outside plate 1, metal micropunch
A plurality of micropores, described metal micropunch outside plate 1 and metal micropunch inner panel 2 are provided with plate 2 and metal micropunch backboard 3
Both sides all at right angles fold there is outside plate folded edge 5 and inner panel folded edge 6, in metal micropunch outside plate 1 and metal micropunch
Plate 2 all becomes U-shaped structure after folding, and described metal micropunch inner panel 2 is arranged in metal micropunch outside plate 1 and forms cavity 1, institute
State outside plate folded edge 5 to fit tightly with inner panel folded edge 6, described metal micropunch backboard 3 arrange both sides inner panel folded edge 6 it
Between form cavity 28, described module mounting plate 4 is arranged on the both sides of metal micropunch backboard 3.
It should be noted that one end outward bending of module mounting plate 4 described in the utility model has kink, it is another
End is connected on metal micropunch backboard 3.
With reference to as shown in figure 1, installation method of the present utility model, an adjustable corner brace 9, adjustable angle are provided with metope 15
On code 9, angle bar code 10 is installed, angle bar code 10 is provided with shaped steel Os Draconis 11, then by U-shaped press strip 12, two modules is absorbed sound
The module mounting plate 4 of plate connects, and through U-shaped press strip 12, module acoustic board is tightened in shaped steel Os Draconis 11 by boring tail nail 13
On, after installation, metal micropunch backboard is formed with metope has cavity 3 14, improves acoustically effective again.
But, above-mentioned specific embodiment is exemplary, is to preferably enable those skilled in the art
Understand this patent it is impossible to be not understood as this patent is included with the restriction of scope；As long as the institute of spirit according to disclosed in this patent
Any equivalent change made or modification, each fall within the scope that this patent includes.
