Abstract

The utility model discloses a light composite down pipe, which is characterized in that the down pipe is made into a composite wall composed of five layers or more than five layers of magnesia cement layers and enhancement layers, that is to say, the down pipe is formed by a magnesia cement layer, an enhancement layer, a magnesia cement layer, an enhancement layer and a magnesia cement layer in turn, and the amount of the layers of the down pipe can achieve five or other odd numbers above five by analogy. The magnesia cement in the middle magnesia cement layer is mixed with lightweight fiber materials. The pipe body is composed of a pipe shaft and a pipe joint. The enhancement layer is made of glass fiber cloth, metal nets or plastic fibers. The lightweight fiber material is saw dust, rice husks, rice straws or bamboo filaments. The pipe has the advantages of smooth and beautiful appearance, high intensity and light weight, which is a good substitute product for the existing cast iron, metal down pipe and plastic down pipe.

Description

Light composite down pipe

The utility model belongs to the vertical duct in the fitting-out work of building, relates to a kind of lightweight composite down pipe.

Existing leader mostly is cast iron pipe, the metal light wall pipe, plastic pipe: cast iron pipe easily has the easy rust of sand holes easily to come off, disreputable looking is seen, coarse rough easy obstruction in the pipe, the metal light wall pipe easily rust mashed damaged application life low and valency is high, the plastic pipe not long-time high temperature low-temperature deformation of ability rate is big, and application number is 89101399.7 patent of invention, provide a kind of and added the lightweight sulphur glass rainwater pipe that relevant modified additive is the major ingredient generation with magnesia cement, but its main body framework has only one deck, and its intensity is low and do not reach standard-required, and is therefore impracticable.

The purpose of this utility model is exactly that what a kind of MULTILAYER COMPOSITE will be provided is the lightweight composite down pipe of major ingredient with novel magnesia cement.

Major technique of the present utility model is that its tube wall is by the magnesia cement layer, enhancement layer is formed, have and mix the composite of oozing the light fibre material more than five layers or five layers in the middle of the odd-level, it is one deck magnesia cement, one deck enhancement layer, one deck magnesia cement layer, one deck enhancement layer, one deck magnesia cement layer, reach odd-level more than five layers or five layers by that analogy, mix in the magnesia cement wherein in the magnesia cement layer and be impregnated with the light fibre material, it is the mixing light layer, body is made pipe shaft and union two parts, and then link into an integrated entity, enhancement layer adopts glass fabric, wire lath or plastic fiber material, the light fibre material can adopt sawdust, straw, bamboo silk etc., the bonding bonding force between layer and the layer by magnesia cement itself.

The utility model smooth in appearance is attractive in appearance, and intensity height and light weight are the good substitute products of leaders such as cast iron, metal, plastics.

Concrete structure of the present utility model is provided by following examples and accompanying drawing.

The cross-sectional view of Fig. 1, five layers of lightweight composite down pipe.

Fig. 2, the cross-sectional view of seven layers of lightweight composite down pipe.

Glass fiber layer of cloth 11, the magnesia cement layer 12 of the glass fiber layer of cloth 7 of the glass fiber layer of cloth 4 of the glass fiber layer of cloth 2 of magnesia cement layer 1,02 specification, mixing light layer 3,02 specification, magnesia cement layer 5, magnesia cement layer 6,02 specification, the glass fiber layer of cloth 9 of magnesia cement layer 8,02 specification, mixing light layer 10,02 specification.

In conjunction with Fig. 1, the tubulation process of five layers of lightweight composite down pipe is layered on the workbench for the film that will not have wrinkle, then magnesia cement being layered on maintains an equal level on the film makes magnesia cement layer 1 to 2MM, then on magnesia cement layer 1, put one deck 02 specification glass fiber layer of cloth 2, floatingly soaked glass cloth to magnesia cement, mix the mixing light layer 3 that oozes together at this layer upper berth one deck magnesia cement and light material again, this layer thickness is 3MM, on mixing light layer 3, put one deck 02 specification glass fiber layer of cloth 4 again, add one deck 1 again, the magnesia cement layer 5 that 5MM is thick, go into contour forming after leaving standstill a period of time, the structure and material of union is identical with pipe shaft, just the interior cross section of the cross section of union internal mold and pipe shaft external mold is identical, treat tubularly to take off external mold again to take off internal mold earlier after fixed, according to dimensional requirement cut pipe range, union is finished product after the field joint.The tubulation process of seven layers of lightweight composite down pipe also approximately so.

The magnesia cement layer in the pipe and the selection of enhancement layer, can decide according to intensity, when intensity reached certain requirement, the lightweight composite down pipe can also be used in other supplying drainages, one deck magnesia cement layer of tube outer surface can infiltrate colored materials and make color tube.
