Abstract
The utility model discloses a double layer damping sound insulation plate used for insulating indoors noise, preventing the noise pollution to the outdoors environment caused by the indoors noises and guaranteeing body health of people. The plate comprises a frame with grooves, a sound absorption plate, an inner layer fireproof plate, an outer layer fireproof plate and a protection plate; the sound absorption plate is inserted into the groove of the frame, while is surrounded by the frame; the inner layer fireproof plate is mounted on the lower surface of the sound absorption plate; the outer layer fireproof plate is mounted on the upper surface of the sound absorption plate; and the protection plate is mounted outside the outer layer fireproof plate. The double layer damping sound insulation plate of the utility model has obviously reduction effect to the medium/low frequency noises, can isolate the indoors noises from spreading outdoors, avoids the noise pollution to the outdoors environment caused by the indoors noises, protects body health of people; and has a light weight and a low cost, and can be stepped on.
Description
Technical field
The utility model relates to a kind of noise processed equipment, in particular, relates to a kind of double-deck damping sound barrier that is used for noise processed.
Background technology
At present, along with the reinforcement of people's environmental consciousness, noise pollution more and more is subject to people's attention.Usually on some equipment, add equipment such as vibration damping, noise elimination, to slacken noise.But the source of room noise is varied at present, and some equipment does not have good measure to install the vibration-absorbing and silencing device additional, and indoor noise passes to outdoor by the roof, influenced the life of surrounding resident, and the healthy of people threatened.As the kitchen in restaurant, the noise that burner in the kitchen produces often sees through the individual layer colored steel roof influences external environment, on-the-spot test (12 noon, kitchen section running time), 3 meters distances nearby, two layers of position of residential building, 65 decibels of noises.At present, also there are not effective measures that the burner noz(zle) noise is administered.
The utility model content
The utility model is in order to overcome weak point of the prior art, a kind of double-deck damping sound barrier to be provided, with the noise in the air lock, prevent the noise pollution of room noise to outdoor environment, ensures that people's is healthy.
The utility model is achieved through the following technical solutions:
A kind of double-deck damping sound barrier, it is characterized in that, comprise by the quadrilateral frame that has groove, acoustical board, internal layer PLASTIC LAMINATED, outer PLASTIC LAMINATED, protected apron, described acoustical board inserts in the groove of framework, the internal layer PLASTIC LAMINATED is installed on the soffit of described acoustical board, outer PLASTIC LAMINATED is installed on the upper surface of described acoustical board, and the outside of described outer PLASTIC LAMINATED is equipped with protected apron.
Described acoustical board is rock cotton board or glass wool board.
It is 80-120 that described acoustical board adopts thickness, and density is the rock cotton board of 40-80kg/ cubic meter.
It is the steel plate of 1-3mm that described protected apron adopts thickness.
The thickness of described internal layer PLASTIC LAMINATED and outer PLASTIC LAMINATED is respectively 4-8mm.
The steel plate that described framework employing thickness is 1-1.5mm processes.
The utlity model has following technique effect:
Double-deck damping sound barrier centering low-frequency noise of the present utility model has tangible noise reduction effect, can cut off room noise to outdoor propagation, avoids the noise pollution of room noise to outdoor environment, and the guarantee people's is healthy.And, in light weight, cost is lower, can trample.
Description of drawings
Fig. 1 is the sectional view of the double-deck damping sound barrier of the utility model.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in detail.
Fig. 1 is the sectional view of the double-deck damping sound barrier of the utility model, comprises the quadrilateral frame 4, acoustical board 3, internal layer PLASTIC LAMINATED 5, outer PLASTIC LAMINATED 2, the protected apron 1 that have groove, and acoustical board inserts in the groove of framework.Internal layer PLASTIC LAMINATED 5 is installed on the soffit of acoustical board 3, outer PLASTIC LAMINATED 2 is installed on the upper surface of described acoustical board 3, the outside of outer PLASTIC LAMINATED 2 is equipped with protected apron 1.
Wherein, described acoustical board is rock cotton board or glass wool board.In order to reduce cost, it is that 80-120mm, density are the rock cotton board of 40-80kg/ cubic meter that acoustical board adopts thickness.It is the steel plate of 1-3mm that described protected apron adopts thickness.The thickness of described internal layer PLASTIC LAMINATED and outer PLASTIC LAMINATED is respectively 4-8mm.The steel plate that described framework employing thickness is 1-1.5mm processes.
In the processing of room noise, by the processing of insulating against sound of sound insulation roofing.Utilize main building thing Structure Beam-column and body of wall, support No. 12 square steel, as new roof girder, do austere with No. 5 square steel, additional column is done with No. 10 channel-section steels in necessary position, sets up new roof truss structure, the double-deck damping sound barrier of the present utility model of mating formation on this roof truss.The characteristics that sound barrier of the present utility model has is in light weight, cost is lower, can trample, the centering low-frequency noise has obvious noise reduction effect.Engineering finishes after on-the-spot test, and the noise of position, roof is reduced to 45 decibels by original 65 decibels, and dynamically sound insulation factor reaches 20 decibels.
Although relate to a kind of double-deck damping sound barrier and carried out special description disclosed with reference to embodiment, embodiment described above is illustrative and not restrictive, under the situation that does not break away from spirit and scope of the present utility model, all variations and modification are all within scope of the present utility model.
