Abstract

The utility model relates to a rain discharge pipe of steel netted concrete, which is installed on buildings. Like the present rain discharge pipe, the utility model is composed of a supported joint (1) and a pipe barrel (2). Different from the present rain discharge pipe, a steel net formed by braiding fine steel wires is axially buried in concrete in a looping mode, the diameter of the pipe can be restricted within 100MM, the thickness of a pipe wall ranges from 10MM to 15MM, and the availability of the pipe barrel reaches 1.5 M. The utility model can bear an external pressure destroy load of 15 kilonewtons / M, and can bear inner water pressure of 0.4 megapascal. The utility model has the advantages of half price of a cast iron pipe of the same specification, no corrosion, no aging, smooth and clean appearance and long service life.

Description

Rain drainage of steel netted cement

The utility model relates to the defeated pipe fitting of rainwater row that a kind of device uses, particularly a kind of steel mesh Concrete rain blow-off pipe on building.

At present, the storm sewage pipe that installs on building generally all is to use cast iron pipe or plastic pipe.As everyone knows, cast iron pipe is corrosion very easily, safeguards that as not noting japanning its application life is just very limited; The application life of plastic pipe is just shorter, and should not be installed in outdoor use, otherwise the embrittlement of will wearing out in one or two years; Pottery storm sewage pipe can only be to be contained on the high-grade special building, because of its price is too high, can not use on common building.People want to use cement to make the storm sewage pipe for a long time, because thinking is confined to the intrafascicular approximately of reinforced concrete structure, lack special process equipment again, so fail always to make that water pressure resistance 0.06 MPa is above, wall thickness is below 15 millimeters, socket length surpasses 1.The storm sewage pipe that 5 meters light and handy, practical cement is made.

The purpose of this utility model to the public provide a kind of simple in structure, be easy to make, price is low, the storm sewage pipe that cement light and handy, solid, attractive in appearance is made.

Introduce for convenient, the technical solution of the utility model and specific embodiment are comprehensively described in detail below in conjunction with accompanying drawing.

Fig. 1 is a structural profile diagrammatic sketch of the present utility model.

The contour structures of this novel storm sewage pipe and general cast iron pipe, plastic pipe are the same, be by accepting partly formation of head (1) and socket (2) two, when different is its making, to put in pipe die along the axial lopping of tube core as the muscle net with the steel mesh of fine wire braiding earlier, and the cement, the fine stone concrete that stir sent in the pipe die, again through rotating pipe die, and backer roll is centrifugal in pipe die core hole rolls, steel mesh is embedded in cement and the fine stone concrete along the axial lopping of tube core, after the health coagulation forming promptly obtains finished product after the demoulding.

This novel storm sewage pipe can be filled up the blank of cement tube product category, its caliber can be in 100 millimeters, pipe thickness is 10～15 millimeters, the socket effective length reaches 1.5 meters, can bear the external pressure rupture load and reach 15,000 Ns/rice, hydraulic pressure can reach 0.4 MPa in bearing, and every performance indications all meet or exceed the technical standard requirement of relevant all kinds of storm sewage pipes; Its price only is half of cast iron pipe price of same size, can corrosion, and also aging, and also outward appearance is bright and clean level and smooth, and can " live a long life together " its application life with building.

Claims

1, the rainwater row defeated pipe fitting of a kind of device on building, particularly a kind of steel mesh Concrete rain blow-off pipe constitutes by accepting head (1) and socket (2), and it is characterized in that: steel mesh (3) direct-axis is embedded in cement and the fine stone concrete to lopping.
