Description
Technical field
The utility model relates to a kind of sound insulating panel, particularly a kind of foam aluminium sandwich sound insulating panel.
Background technology
Along with the development rapidly of society, the surrounding enviroment of life there is increasing noise in us, these noises seriously annoying the normal life of people, therefore some families or office building can on metope sound insulation materials in docile, these sound insulation materialss are generally employing sponges, foamed plastics is made, although good soundproof effect can be played, easily light; Also some adopts asbestos, hollow glass, fibrous material and acoustic brick, although be not easy to light, soundproof effect is not good.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of foam aluminium sandwich sound insulating panel that can not burn and have fine soundproof effect.
In order to solve the problem, originally being the technical scheme of novelty is: a kind of foam aluminium sandwich sound insulating panel, comprise housing, base plate and composite bed, one is provided with the cavity of opening in described housing, composite bed is positioned at cavity, and be provided with gap between an end face of composite bed and cavity inner wall face, base plate is arranged on the end face of opening, described composite bed comprises and is alternately arranged on polylith foamed aluminium board in cavity and polylith aluminium alloy plate, between adjacent foamed aluminium board and aluminium alloy plate, be provided with gap.
Further, in cavity, many are provided with for settling the draw-in groove of foamed aluminium board or aluminium alloy plate.
Further, the housing near opening is provided with screwed hole, base plate by screw hole on opening.
Between housing and composite bed, be provided with multiple gap, and then the multiple reflections of sound wave in gap can be utilized, reduce the propagation of sound; Foamed aluminium material not only can not burn simultaneously, and there is the effect of good sound insulation and noise reduction, aluminium alloy plate not only can not burn, and it is lightweight high with intensity, the intensity of whole composite bed can be improved, therefore the utility model not only anti-knock shock resistance but also high temperature resistant but also the soundproof effect arrived very much can be played.
On the basis of technique scheme, the utility model can also do following improvement,
Preferably, in the second gap, asbestos are filled with.
The filling of asbestos, can become by composite bed into an entirety, while the utility model can be made to play fire prevention and soundproof effect, further improves the intensity of whole sound insulating panel.
Preferably, settle in the first gap by many glass tube with vacuums, described glass tube with vacuum comprises the shell of a sealing, is provided with multiple supporting section in the enclosure, supporting section is provided with aspirating hole.
The external world further can be delivered to indoor sound by glass tube with vacuum to be isolated, and further improves soundproof effect.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described further:
Fig. 1 is generalized section of the present utility model,
Fig. 2 is front view of the present utility model,
Fig. 3 is the generalized section of the utility model embodiment 1,
Fig. 4 is the generalized section of the utility model embodiment 2,
Fig. 5 is the generalized section of the utility model glass tube.
Detailed description of the invention
As illustrated in fig. 1 and 2, a kind of foam aluminium sandwich sound insulating panel, comprise housing 1, base plate 4 and composite bed, one is provided with the cavity 15 of opening in described housing 1, composite bed is positioned at cavity 15, and be provided with the first gap 11 between an end face of composite bed and cavity 15 internal face, base plate 4 is arranged on the end face of opening, described composite bed comprises and is alternately arranged on polylith foamed aluminium board 3 in cavity 15 and polylith aluminium alloy plate 2, is provided with the second gap 14 between adjacent foamed aluminium board 3 and aluminium alloy plate 2.
Further, in cavity 15, many are provided with for settling the draw-in groove 12 of foamed aluminium board 3 or aluminium alloy plate 2.
Further, the housing 1 near opening is provided with screwed hole 13, and base plate 4 is screwed onto on opening by screwed hole 13.
Enter among the first gap 11 at sound wave from the external world, in the first gap 11, repeatedly there is reflection eliminate the noise, again enter into the energy of composite bed internal consumption sound wave, eliminate the noise in composite bed and be achieved in that sound wave produces diffuse reflection in the second gap 14, now sound wave can drive the empty structure in foamed aluminium board 3 to vibrate, reduce the energy of sound wave, sound wave after weakening enters in second the second gap 14, sound wave weakens by second the second gap 14 again, after the weakening of multiple tracks second gap 14, composite bed is finally made to have good soundproof effect.
As shown in Figure 3, embodiment 1 of the present utility model: preferred, is filled with asbestos 5 in the second gap 14.The filling of asbestos 5, composite bed can be become an entirety, centre does not have gap, while the utility model can be made to play fire prevention and soundproof effect, further improves the intensity of whole sound insulating panel.
As shown in Figures 4 and 5, embodiment 2 of the present utility model: settle by many glass tube with vacuums 6 in the first gap 11, described glass tube with vacuum 6 comprises the shell 63 of a sealing, is provided with multiple supporting section 61, supporting section 61 is provided with aspirating hole 62 in shell 63.The external world further can be delivered to indoor sound by glass tube with vacuum 6 to be isolated, further raising soundproof effect, supporting section 61 wherein serves the intensity strengthening whole glass tube with vacuum 6, and the effect of aspirating hole 62 is to be convenient to processing and fabricating glass tube with vacuum 6.
