Abstract
The utility model relates to a sound-deadening sound-proof building draining tubular product, which is composed of an inner tube body (1), an outer tube body (2) and reinforcing ribs (3). The utility model is characterized in that the inner tube body (1) and the outer tube body (2) are formed a double-layer tube body through the fixed connection of the reinforcing ribs (3); the inner wall of the inner tube body (1) is provided with a spiral diversion main bulge (4) and a spiral diversion auxiliary bulge (5). The utility model has the advantages of simple structure, novel design, sound deadening, sound proofing, heat proofing, high pressure resistance strength and strong shock resistance, and is an ideal sound-deadening sound-proof building draining tubular product with a double-layer structure.
Description
The utility model relates to a kind of noise reduction sound insulation construction drainage tubing, relates to a kind of its inside pipe wall specifically and is provided with the spiral stream guidance projection, and double-deck, compressive strength is big, and anti-impact force is strong, but the drainage pipe of noise reduction sound insulation.
At present, along with the fast development of builing industry, the constructional materials on the market also more and more comes many, and constructional materials miscellaneous enriches and enriching market, to satisfy people's needs.Yet existing drainage pipe is traditional single layer structure mostly still, and inside pipe wall is smooth circular pipe.The tubing of the single layer structure of this inner wall smooth, because its structural reason, compressive strength is low, a little less than the anti-impact force, noise reduction, sound insulation, heat insulation weak effect are so usually can not satisfy people's needs in the construction of existing drainage pipe.So the structure of existing drainage pipe needs further improvement.
The purpose of this utility model is to design a kind of its inside pipe wall and is provided with the spiral stream guidance projection, and double-deck noise reduction sound insulation construction drainage tubing is to overcome the deficiencies in the prior art.
The purpose of this utility model is to realize like this, it is made up of interior tube body (1), outer tube body (2) and reinforcing rib (3), it is characterized in that: interior tube body (1) and outer tube body (2) become double-deck body by reinforcing rib (3) is affixed, and the inwall of interior tube body (1) is provided with spiral stream guidance master projection (4) and the secondary projection of spiral stream guidance (5).
The utility model compared with prior art, it is simple in structure, modern design can noise reduction, sound insulation and heat insulation, compressive strength is big, anti-impact force is strong, is a kind of desirable double-deck noise reduction sound insulation construction drainage tubing.
Below in conjunction with drawings and Examples the utility model is further specified:
Accompanying drawing 1 is the utility model broken section structural representation.
Accompanying drawing 2 is the utility model cross-section structure.
Wherein: 1, interior tube body, 2, outer tube body, 3, reinforcing rib, 4, spiral stream guidance master projection, 5, the secondary projection of spiral stream guidance.
Referring to accompanying drawing: it is by interior tube body 1 as seen from the figure, outer tube body 2 and reinforcing rib 3 are formed, interior tube body 1 and outer tube body 2 become double-deck body by reinforcing rib 3 is affixed, be formed with the sound insulation hole around the double-deck body, the inwall of interior tube body 1 is provided with spiral stream guidance master projection 4 and the secondary projection 5 of spiral stream guidance, the inwall that is to say interior tube body 1 is provided with spiral helicine projection, present embodiment spiral stream guidance master projection 4 is provided with the 3-12 bar, the secondary projection 5 of spiral stream guidance is provided with the 30-100 bar, reinforcing rib 3 (or sound insulation hole) is provided with 16-80, during use, because the effect of spiral stream guidance master projection 4 and the secondary projection 5 of spiral stream guidance makes when water or other fluid flow in pipe, form with rotation is advanced, central authorities form the void column shape, and ventilation power is improved, and drainability strengthens, noise reduces, in addition, because the utility model is double-deck body, so the noise reduction sound insulation is effective, compressive strength is big, and anti-impact force is strong.
Claims (1)
1, a kind of noise reduction sound insulation construction drainage tubing, it is made up of interior tube body (1), outer tube body (2) and reinforcing rib (3), it is characterized in that: interior tube body (1) and outer tube body (2) become double-deck body by reinforcing rib (3) is affixed, and the inwall of interior tube body (1) is provided with spiral stream guidance master projection (4) and the secondary projection of spiral stream guidance (5).
