Abstract
The utility model discloses a hollow-wall plastic pipe product, and comprises an inner wall and an outer wall of the pipe product; the utility model is characterized in that at least a layer of supporting ring is arranged between the inner wall and the outer wall, and a reinforcing bar leads the outer wall and the inner wall to be connected together through the supporting ring. The hollow wall plastic pipe product of the utility model at least comprises two layers of hollow walls, which are only connected through the reinforcing bar, so as to form a honeycomb hole, in this way, the medium function of further weakening sonic propagation can be played, thereby, the drainage noise is greatly reduced. The multi-story building drainage noise is always a large difficult problem of influencing the living quality of people, the hollow wall plastic pipe product of the utility model well solves the difficult problem. At the same time, compared with a solid-wall pipe with the same thickness, and under the circumstance that the strength and the ring rigidity cannot be reduced, the material consumption is reduced, and the cost is reduced.
Description
Technical field
The utility model relates to pipeline material, specifically, relates to a kind of hollow wall plastic tube.
Background technique
The historical experience of countries in the world in modernization shows, the development speed of plastic pipe is all above the rate of economic development same period, replacing conventional pipelines with plastic pipe is the irresistible trend of economic development, even in the developed country that builds up the plastic tube network that gathers, the application quantity of plastic tube still increases in every year.
In the prior art, the hollow wall plastic tube is an individual layer, connects the tubing inner and outer wall by stiffening rib and constitutes.Inwall is the internal surface of tubing, its size decision water flowing area, and Kong Yueda, the water flowing area is big more.Outer wall is the outer round surface of tubing.Form approximate square hole between the stiffening rib, this square hole runs through whole tubing vertically, forms hollow wall.Sound wave is propagated by medium, as long as weaken medium, noise will diminish.Thereby, therefore reduced noise because the existence of square hole weakens medium.
On November 24th, 2004 bulletin, notice of authorization number discloses a kind of hollow wall plastic tube for the Chinese utility model patent that CN265816Y, name are called " the empty wall plastic tube of band screw rib ".The improvement of this model utility is with stiffening rib, and promptly to become with the pipe centerline be the spiral helicine rib of lead to the alleged rib of this patent, overcome in the prior art, lineal shape cracking in axial direction, to noise further reduce do not have much influences.
Along with living standards of the people improve, to the also progressively requirement raising of quality of life.Energy-saving and environmental protection, hommization are the requirements new to chemical building material.Given this, be necessary further to reduce drainage noise.
Summary of the invention
Goal of the invention of the present utility model is to overcome above-mentioned deficiency of the prior art, provides a kind of drainage noise littler hollow wall plastic tube.
For achieving the above object, hollow wall plastic tube of the present utility model comprises pipe material inner wall and outer wall, and one deck support ring is at least arranged between inner and outer wall, and stiffening rib links together outer wall and inwall by support ring.
For further improving noise reduction, the stiffening rib between stiffening rib between inwall and the support ring and outer wall and the support ring is interspersed.
Goal of the invention of the present utility model is achieved in that the section from tubing, and it is the stepping at least three layers of annulus of diameter, and promptly inwall, support ring, outer wall connect by stiffening rib, has constituted a lot of honeycomb structures that section is evenly arranged like this.Sound wave is propagated by medium, as long as weaken medium, noise will diminish.Hollow wall plastic tube of the present utility model has double-deck empty wall at least, the layer with the layer between just be connected by stiffening rib, formation honeycomb structure, played the medium effect that further weakens acoustic wave propagation like this, thereby, greatly reduce drainage noise.The multi-storey building drainage noise is a great problem that influences people's living standard always, and the utility model hollow wall plastic tube has solved this difficult problem preferably.Simultaneously, compare, under the situation that intensity and ring stiffness can not reduce, reduced the consumption of material, reduced cost with the same thickness solid wall pipe.
Description of drawings
Fig. 1 is the sectional view of prior art hollow wall plastic tube;
Fig. 2 is a kind of embodiment sectional view of the utility model hollow wall plastic tube;
Among the figure, 1-inwall 2-outer wall 31,32-stiffening rib 4-square hole 5-support ring.
Embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model hollow wall plastic tube is described in further detail.
Fig. 1 is the sectional view of prior art hollow wall plastic tube.Among the figure, the hollow wall plastic tube is an individual layer, is made of stiffening rib 3 connection pipe material inner walls 1 and outer wall 2.Inwall 1 is the internal surface of tubing, its size decision water flowing area, and Kong Yueda, the water flowing area is big more.Outer wall 2 is outer round surface of tubing.Form the square hole 4 of squarish between the stiffening rib, this square hole 4 runs through whole tubing vertically, forms hollow wall.Sound wave is propagated by medium, as long as weaken medium, noise will diminish.Thereby, therefore reduced noise because the existence of square hole 4 weakens medium.
Fig. 2 is a kind of embodiment sectional view of the utility model hollow wall plastic tube.Among the figure, the hollow wall plastic tube is double-deck hollow wall, comprise pipe material inner wall 1 and outer wall 2, one deck support ring 5 is arranged between inner and outer wall, stiffening rib 31,32 links together outer wall 1 and inwall 2 by support ring 5, and stiffening rib 31 between inwall and the support ring and the stiffening rib 32 between outer wall and the support ring are interspersed.Section from tubing, it is the stepping three layers of annulus of diameter, be inwall 1, support ring 5, outer wall 2 connects by stiffening rib 31,32, constituted the square hole 4 of a lot of cellular squarish that section evenly arranges like this, this square hole 4 runs through whole tubing vertically.
The hollow wall plastic tube of the utility model mode of execution is double-deck empty wall, the layer with layer between just be connected by the stiffening rib 31,32 that is interspersed, and the square hole 4 that is interspersed that forms, played the medium effect that further weakens acoustic wave propagation like this, thereby, greatly reduce drainage noise, solve the multi-storey building drainage noise is a great problem that influences people's living standard always, according to test, drainage noise can reduce about 15 decibels.
The utility model hollow wall plastic tube is not limited to the scope of embodiment, and present embodiment just helps to understand the utility model, and all innovation and creation that utilize the utility model design are all at the row of protection.
