The specific embodiment
As shown in Figure 1, cuboid framework 1 constitutes the main body frame of the utility model noise-reducing and dustproof mobile operating room, and the bottom of framework 1 is equipped with four castors 3, and wherein two is universal wheel, and two is directional wheel.But universal wheel fixed-direction 45 degree, 90 degree and 135 degree can move the construction operation chamber arbitrarily in builder's road, the while also possesses brake function.
On the top of framework 1 and four facades acoustical board 2 is installed.
As shown in Figure 3, framework 1 is spliced by a top frame 11, underframe 12 and four root posts 13.Wherein four root posts 13 are made of rectangular steel tube.And underframe 12 is surrounded by threshold 122 after the front door sill 124, and two side door sill 123, utilize the threshold pin to interconnect, and four bights be provided with 125, four castors 3 of four corner posts be installed in four corner posts 125 below, four root posts 13 can insert in four corner posts 125.Four bights of top frame 11 are fixed with four inserting columns 113 that extend downwards, and inserting column 113 can insert in four root posts 13, thereby is spliced into the framework 1 of a cuboid, and it is convenient to assemble, the packaging efficiency height.In order to guarantee the fastness of framework 1, it is fastening to adopt securing member to carry out at some connecting portions of said modules.When needs transported, the framework 1 that above-mentioned volume is bigger can be dismantled at an easy rate again and be little, the lightweight assembly of above-mentioned volume, thereby was convenient to transportation, need not to use special crane gear.
Front door sill 124 and back threshold 122 activity threshold, its structure for overturning as shown in Figure 5, its top 101 is fixing part, its underpart 102 is connected with top 101 by hinge 103.When work-room need move forward and backward, bottom 102 is flipped up and fixes with latch, before and after can strengthening like this threshold to the distance on road surface, thereby make work-room when mobile, the obstruction of the native stone on the road surface of can avoiding constructing.
Around the top frame 11 and underframe 12 all around be fixed with the U-shaped chute, and the opening of the U-shaped chute 121 on the U-shaped chute 111 on the top frame 11 and the underframe 12 is relative, the acoustical board 23 on 1 four facades of framework just is embedded in these U-shaped chutes; Also be fixed with two on the top frame 11 and split mouthful flat opposed U-shaped chute 112 of horizontal saliva, the horizontal acoustical board 21 at framework 1 top just is embedded in these two pairs of U-shaped chutes 112.For ease of carrying, top frame 11 is connected to form by bolt by two identical half-breadth frameworks. Acoustical board 21,23 can be installed in the U-shaped chute at an easy rate, also can pull down from the U-shaped chute at an easy rate.Between adjacent two acoustical boards the rubber bar can be set, prevent that noise from passing to the external world by the slit between plate and the plate.Consider ventilated in the work-room, totally-enclosed acoustical board is not adopted at the top, framework 1 top is except that horizontal acoustical board 21, also be provided with the inclination acoustical board 22 of two 45 degree, as shown in Figure 2, on framework 1, be provided with diagonal brace 25, the both sides of inclination acoustical board 22 are installed on the diagonal brace 25, so both can be ventilated, the noise section that inclination acoustical board 22 can make progress vertical or oblique line again absorbs or reflexes in the work-room, has increased top sound insulation area.
Also be provided with Yishanmen plate 24 on the facade of framework 1, door-plate 24 is connected with adjacent acoustical board 23 by the bolt-type hinge, can open or close, and is convenient to constructor's turnover.Acoustical board 23 on door-plate 24 and the facade, the acoustical board at top 21, the 22 common acoustical boards 2 that constitute frameworks 1 surface play the effect of isolating construction noise and dust.
The structure of acoustical board 2 as shown in Figure 4, surround a rectangular shaped rim 201 by rectangular steel tube, the panel 203,205 that is made of color painted steel strip is attached to the both sides of rectangular shaped rim 201, wherein outer side panel 205 is made by the thick color painted steel strip of 1mm, inner panel 203 by the thick color painted steel strip of 0.7mm make (on aperture is arranged, perforated percentage 20%, aperture 5mm), the sound absorption material 206 that is made of centrifugally glass-wool is filled between the both sides panel 203,205.The inboard of the panel 203 one deck glass wool cloth 204 of also fitting.Be provided with bound edge 202 around the acoustical board, make by the 0.7mm color painted steel strip.
The sound insulation factor of acoustical board 2 can be tried to achieve by calculating, and also the chamber actual measurement provides by experiment.General 1.0mm steel plate mean transmission loss is 27.9dB, and the following sound insulation factor of low frequency 250Hz is about 20dB, intermediate frequency 500-1000Hz, and sound insulation factor is about 25dB, high frequency sound insulation factor＞30dB that 1000Hz is above.1.0mm thick aluminium sheet mean transmission loss is 20.5dB, the low frequency sound insulation factor has only about 10dB, and intermediate frequency 15dB is about high frequency 25dB.Present embodiment adopts that 1.0mm is thick to be adopted the thick moistureproof centrifugally glass-wool sound absorption material of steel plate+damping material+50mm (density is 32kg/m
3Steel facing is adopted in the thick perforation of)+0.7mm, and its comprehensive sound insulation factor is investigated with analogy as calculated, mean transmission loss＞30dB.
For reducing the reverberation time in the enclosure space, further reduce the internal and external influence of work-room noise, the processing that should absorb sound of the inboard of acoustical board 2.Present embodiment is selected the thick moistureproof centrifugally glass-wool plate of 50mm for use, and sturdy, density is 32kg/m
3, its sound absorbing capabilities is as follows: average sound absorption coefficient=0.78, the medium-high frequency sound absorbing capabilities is good.
| Frequency (Hz) | 125 | 250 | 500 | 1000 | 2000 | 4000 | Average sound absorption coefficient α |
| Sound absorption coefficient (α) | 0.24 | 0.63 | 0.91 | 0.97 | 0.98 | 0.99 | 0.78 |
Moistureproof centrifugally glass-wool sound absorbing capabilities is stable, is not afraid of humidity, and resilience is good, not needle-holding hand.
Because the spectral characteristics of noise that pneumatic pick produces in work-room system is based on medium-high frequency, so definite acoustical board material, the structure of this enforcement, selected sound absorption material etc. also is to isolate or to absorb medium-high frequency sound, and is very targeted, so noise reduction is good.
In order to guarantee noise reduction, the acoustical board of this structure is installed also on the above-mentioned threshold.
The utility model can provide the space of a relative closure for the place of construction operation, has the function of noise reduction sound insulation preferably, can reduce the influence of construction noise to surrounding environment greatly, the work-room of this sealing simultaneously also can prevent to construct dust to external diffusion.Certainly, also can adopt the mode that atomization mechanism is installed, reduce the dust concentration in the work-room, or take other labour protection measures to reduce the influence of room noise and dust the constructor.
