Abstract
The utility model relates to an environment-friendly composite sound-absorption noise-reduction which is Z-shaped wholly, and is composed of three layers, namely a panel, a composite sound-absorption noise-reduction body and a colored steel plate, wherein the colored steel plate is provided with a groove, a protruded clamping edge is arranged on one side of the groove, the panel is fixed at the clamping edge, and the composite sound-absorption noise-reduction body is clamped between the panel and the colored steel plate. Due to implementation of the technical scheme, the environment-friendly composite sound-absorption noise-reduction board has the advantages of high sound-absorption rate, environmental friendliness, energy saving, good heat insulation property, compact structure, stable shape, light weight, and safety and convenience in construction, and is suitable for compressor rooms, generator rooms, pump rooms, studios, theatres and other environments with more noise sources and complicated sound field.
Description
Technical field
The utility model relates to a kind of environmental protection composite sound-absorbing noise reducing plate.
Background technology
Noise occupies suitable ratio in the industrial operations environment pollution constitutes.The serious harm worker health has become generally acknowledged important environmental hazard.In industrial enterprise's manufacturing process, clash into and flow perturbation generation much noise at present owing to mechanical shock, friction.The noise that for example produces when the air compressor in oil field, ventilation fan and boiler exhaust emptying all is the pneumatic noise that produces owing to air vibration.The noise that water injecting pump, mill and diesel-driven generator etc. produce is because the mechanical noise that vibration of solid part machinery or friction bump produce.Disperse owing to the industrial noise sound source, the noise type more complicated because of the also difficult identification of continuity sound source of producing, administers quite difficulty.
Using at present is on body of wall and roof, to do sound absorption to handle more widely, goes along with sb. to guard him noise source or the like with barrier sound insulation.These ways are applicable to simple simple sund source noise reduction, and most industrial site noise main noise sources is more, sound field is complicated, and present employed method also is not suitable for.
Summary of the invention
The purpose of the utility model is to propose a kind of acoustic absorptivity height, environmental protection and energy saving, thermal insulation is good, structure is tight, and form stable, in light weight, construction safety be environmental protection composite sound-absorbing noise reducing plate easily.
The purpose of the utility model is achieved in that environmental protection composite sound-absorbing noise reducing plate is whole for Z-shaped, and it is made up of for three layers panel, composite sound-absorbing noise reduction body and color steel.Color steel has groove, one side groove be provided with outstanding card rib, card rib place fixed panel, clamping composite sound-absorbing noise reduction body between panel and color steel.
Owing to implement above technical scheme; Make the utility model environmental protection composite sound-absorbing noise reducing plate acoustic absorptivity height, environmental protection and energy saving, thermal insulation is good, structure is tight; Form stable, in light weight, construction safety are convenient, are applicable to compressor room, generator room, pump house, perform in a radio or TV programme that noise sources such as the Room, cinema are more, the sound field complex environment uses down.
Description of drawings: the technical scheme of the utility model is provided by following accompanying drawing and embodiment:
Fig. 1 is an environmental protection composite sound-absorbing noise reducing plate structural representation.
Legend: 1, panel, 2, the sound-absorbing nonwoven layer, 3, environmental-protection damp acoustical cotton layer, 4, color steel, 5, rotary glass silk flosssilk wadding layer, 6, the card rib.
The specific embodiment:
The utility model does not receive the restriction of following embodiment, can confirm concrete embodiment according to the technical scheme and the actual conditions of the utility model.
[0009]Embodiment: as shown in Figure 1, environmental protection composite sound-absorbing noise reducing plate integral body is Z-shaped, and it is made up of for 4 three layers panel 1, composite sound-absorbing noise reduction body and color steel.Color steel 4 has groove, one side groove be provided with outstanding card rib 6, card rib 6 place's fixed panels 1, panel 1 and 4 clamping composite sound-absorbings of color steel noise reduction body.Composite sound-absorbing noise reduction body is made up of the sound-absorbing nonwoven layer 2 of both sides and rotary glass silk flosssilk wadding layer 5, the environmental-protection damp acoustical cotton layer 3 at middle part.
Spread all over aperture on the panel 1, the punching rate is 20%/m
2, hole diameter is not more than three millimeters.
During use, every environmental protection composite sound-absorbing noise reducing plate is end to end, can accomplish splicing fast, fixing subsequently, color steel 4 faces of the environmental protection composite sound-absorbing noise reducing plate that assembly unit is good are fixed on the external wall, and panel 1 is outwardly.The surface layer of aperture and environmental protection composite sound-absorbing noise reducing plate self and original building structure has formed resonant cavity; After sound and panel 1 are had an effect; The air column at aperture place produces strong resonance, and air molecule and hole wall acutely rub, thereby consume acoustic energy in large quantities; Behind the remaining sound wave entering of resonance consumption composite sound-absorbing noise reduction body, cause the vibration of space air molecule.Because the friction of the pore wall of the viscosity resistance of air and air molecule and composite sound-absorbing noise reduction body, acoustic energy is converted into heat energy and loss absorbs sound.
Above technical characterictic has constituted the most preferred embodiment of the utility model, and it has stronger compliance and best implementation result, can increase and decrease inessential technical characterictic according to actual needs, satisfies the needs of different situations.
