The utility model provides a give sound insulation and fall type of making an uproar aluminum pipe, including the aluminum pipe body, inhale sound sponge layer, hollow layer and the foam blanket that gives sound insulation, the aluminum pipe body includes inlayer and skin, the outer wall of inlayer glues to cover and has the sound of inhaling sponge layer, outer inner wall glues to cover there is syllable -dividing foam blanket, inhales to have hollow layer between sound sponge layer and the syllable -dividing foam blanket. The utility model discloses a setting is inhaled sound sponge layer, hollow layer and is given sound insulation the foam blanket and has satisfied the requirement of aluminum pipe to the noise reduction that gives sound insulation, wherein, inhales sound sponge layer and has certain sound ability of inhaling, can greatly improve the syllable -dividings effect of aluminum pipe, and the foam blanket that gives sound insulation all has a good isolation ability to the sound of different frequency, and hollow layer can prevent effectively that sound from outwards propagating, reduces the sound of production in the aluminum pipe, the utility model has the advantages of high, syllable -dividing noise -reducing effect is good for compact structure, reliability.

Description

A kind of sound insulation and noise reduction type aluminum pipe

Technical field

This utility model relates to tubing technical field, and specifically, this utility model relates to a kind of sound insulation and noise reduction type aluminum pipe。

Background technology

Sound insulation and noise reduction is the important topic that modern society faces；Sound insulation and noise reduction traffic and transport field, building field, military field, manufacturing industry and for human health in suffer from important effect。The existing sound insulation tube as sound insulation and noise reduction is mainly the tubing that porous material is made, such sound insulation tube has the drawback that use is limited in scope, and needs when isolating some sound source, by splicing after flat board cutting, to be taken up space relatively larger, and spliced soundproof effect is poor, use install all less convenient。Therefore, those skilled in the art need badly provide a kind of rational in infrastructure, there is the sound insulation and noise reduction type aluminum pipe of good sound insulation noise reduction effect。

Utility model content

The technical problems to be solved in the utility model is: provide a kind of rational in infrastructure, there is the sound insulation and noise reduction type aluminum pipe of good sound insulation noise reduction effect。

This utility model solves its technical problem and be the technical scheme is that a kind of sound insulation and noise reduction type aluminum pipe of offer, including aluminum pipe body, sound-absorbing spongy layer, hollow layer and sound-proof foam layer, described aluminum pipe body includes internal layer and outer layer, the outer wall of described internal layer has covered sound-absorbing spongy layer, the inwall of described outer layer has covered sound-proof foam layer, has hollow layer between described sound-absorbing spongy layer and described sound-proof foam layer。

Preferably, described outer layer is coated with the damping coating layer for sound insulation。

Preferably, described sound-absorbing spongy layer have some sound-absorbing grooves。

Preferably, the thickness of described hollow layer is more than 2mm。

Preferably, described sound-proof foam layer have some irregular crafters。

This utility model provides a kind of sound insulation and noise reduction type aluminum pipe, the aluminum pipe requirement to sound insulation noise abatement is met by arranging sound-absorbing spongy layer, hollow layer and sound-proof foam layer, wherein, sound-absorbing spongy layer has certain sound absorbing power, the soundproof effect of aluminum pipe can be greatly enhanced, the sound of different frequency is respectively provided with good isolating power by sound-proof foam layer, hollow layer can effectively prevent sound from outwards propagating, reduce the sound produced in aluminum pipe, the advantage that this utility model has compact conformation, reliability is high, sound insulation noise reduction effect is good。

Accompanying drawing explanation

In order to be illustrated more clearly that the technical scheme in this utility model embodiment, the accompanying drawing used required in embodiment will be briefly described below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the premise not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings。

Fig. 1 is the structural representation of sound insulation and noise reduction type aluminum pipe preferred embodiment of the present utility model。

[in figure accompanying drawing labelling]:

10. internal layer, 20. outer layers, 30. sound-absorbing spongy layers, 40. hollow layers, 50. sound-proof foam layers。

Detailed description of the invention

For making content of the present utility model clearly understandable, below in conjunction with Figure of description, content of the present utility model is described further。Certain this utility model is not limited to this specific embodiment, and general replacement the known by those skilled in the art is also covered by protection domain of the present utility model。Secondly, this utility model utilizes schematic diagram to carry out detailed statement, and when describing this utility model example in detail, for the ease of illustrating, schematic diagram, should in this, as to restriction of the present utility model not according to general ratio partial enlargement。

Above-mentioned and other technical characteristic and beneficial effect, will in conjunction with the embodiments and accompanying drawing 1 sound insulation and noise reduction type aluminum pipe of the present utility model is described in detail。As it is shown in figure 1, Fig. 1 is the structural representation of sound insulation and noise reduction type aluminum pipe preferred embodiment of the present utility model。

As shown in Figure 1, this utility model provides a kind of sound insulation and noise reduction type aluminum pipe, including aluminum pipe body, sound-absorbing spongy layer 30, hollow layer 40 and sound-proof foam layer 50, aluminum pipe body includes internal layer 10 and outer layer 20, the outer wall of internal layer 10 has covered sound-absorbing spongy layer 30, the inwall of outer layer 20 has covered sound-proof foam layer 50, there is between sound-absorbing spongy layer 30 and sound-proof foam layer 50 hollow layer 40, wherein, sound-absorbing spongy layer 30 has some sound-absorbing grooves, to further enhance sound-absorbing effect, sound-proof foam layer 50 has some irregular crafters, the scrambling of bubble and three-dimensional make it possess excellent sound damping。

In order to improve the noise insulation effect of aluminum pipe further, outer layer 20 is coated with the damping coating layer (not shown) for sound insulation。
