Abstract
The invention discloses a spiral-steel-strip-reinforced drainage pipe which comprises a pipe wall formed by spirally rolling a sheet strip, wherein both sides of the sheet strip are each provided with an overlapping part; the overlapping parts of every two adjacent sheet strips overlap each other; a profile steel strip is wound outside the sheet strip; and an integrally formed plastic is coated outside the sheet strip and sheet strip overlapping part and outside the sheet strip overlapping part and profile steel strip. An adhesive is attached outside the joint of every two adjacent sheet strip overlapping parts so as to greatly enhance the tensile strength and sealability of the joint, so that the drainage pipe can not be easily damaged due to stretching in the production and use process.
Description
Technical field
The present invention relates to a kind of municipal drainage pipeline, be specifically related to a kind of helical steel band and strengthen waste pipe.
Background technique
Polythene drainpipe has lightweight, easy construction, and tube wall is highly polished, fluid resistance is little, corrosion-resistant, the features such as long service life.But the rigidity of polyvinyl plastics waste pipe is lower, reach usage requirement must increase waste pipe ring stiffness by increasing wall thickness, this just makes the materials of waste pipe greatly increase.Usually open by the mode increasing steel rib the ring stiffness improving tubing in prior art.If Authorization Notice No. is the China of CN202144625U
model utilitya kind of steel-plastic composite drain pipe disclosed in patent, has mainboard band, and install spirality shaped steel at mainboard band outer wall by deck, shaped steel outer wall is coated with face glue, above mainboard band, be provided with reinforcement strip between amphitypy steel, and the top of shaped steel is higher than reinforcement strip.Such design, enhances the ring stiffness of waste pipe, but has only done bonding process due to the overlapping part between mainboard band, and the tensile strength at this place is low, is easy to cause expendable tension fracture in the process of producing or use, and affects the working life of waste pipe.
Summary of the invention
The technical problem to be solved by this invention sticky seam place be to provide between a kind of adjacent strip connects closely, good seal performance, and the helical steel band that tensile strength is large strengthens waste pipe.
For solving the problems of the technologies described above, the technical solution used in the present invention is as follows:
Helical steel band strengthens waste pipe, comprise the tube wall be made up of strip helical coil, described strip both sides are respectively clinch, after rolling, the clinch of adjacent strip overlaps mutually, outside strip, be wound with profiled strip, be all coated with integrated plastic cement outward at strip, strip clinch and strip clinch and profiled strip.
In order to strengthen the ring stiffness of waste pipe further, such scheme is preferred, and described profiled strip is n shape structure, comprises arc top, sidepiece that two ends, arc top extend to form, the sidepiece lower end outwards leg that is bent to form of top downwards.
In order to improve the embedding and degree of profiled strip, such scheme is preferred, and described strip is provided with at least 1 to projection, and 2 projections in often pair of projection are bent to form buckle all relatively, and the leg of profiled strip withstands in buckle.
Such scheme is preferred, and in order to improve the tensile strength of strip clinch further, the length of described clinch is 15-25mm.
Such scheme is preferred, and the arc length of described profiled strip is 50-220mm, and rise is 20-120mm.
Compared with prior art, the present invention is outside attached glue in the joint of adjacent strip clinch, can improve the tensile strength of joint and the sealing of joint greatly, so make waste pipe production and using process not easily impaired because of stretching; Simultaneously also be coated with plastic cement outward in strip and profiled strip, and the plastic cement of strip, strip clinch and strip clinch and profiled strip outer cladding is one-body molded, further increases tensile strength and the overall performance of waste pipe; The present invention also has the feature that lightweight ring stiffness is high, workable, yield rate is high in addition.

Embodiment
The present invention is that a kind of helical steel band strengthens waste pipe,
as Fig. 1, shown in 2, comprise the tube wall 1 be made up of polylith strip 2 helical coil.Described strip 2 both sides are respectively clinch 3, side clinch 3 upwards foreign side's cross break, and opposite side clinch 3 is foreign side's cross break downwards, and both work in coordination, and are formed and closely overlap, and are fixed by viscose glue 7.After rolling, the clinch 3 of adjacent strip 2 overlaps mutually, outside strip 2, be wound with profiled strip 4, outside strip 2, strip 2 clinch 3 and strip 2 clinch 3 (i.e. the joint of strip 2 and strip 2) and profiled strip 4, be all coated with integrated plastic cement 6.Outside the joint of strip 2 and strip 2 (
fig. 2in be shown as the top of strip 2 and the joint of strip 2) be coated with plastic cement 6, the tensile strength of joint can be improved greatly.
Described profiled strip 4 is n shape structure, comprises arc top 4-1, sidepiece 4-2 that 4-1 two ends, arc top extend to form, the sidepiece 4-2 lower end outwards leg 4-3 that is bent to form of top downwards.Arc top 4-1 and arc-shaped transition, to sidepiece 4-2, can strengthen the ring stiffness of profiled strip 4, and then improve the usability of waste pipe.In addition when waste pipe pressurized, arc top 4-1 can make that pressure can be mild excessively to the wall body of waste pipe, improve the anti-pressure ability of waste pipe.The rise of profiled strip 4 and arc length determine its ring stiffness, thus the rise of profiled strip 4 and arc length extremely important, in the preferred embodiment, the arc length of described profiled strip 4 is 50-220mm, and rise is 20-120mm.
Described strip 2 is provided with at least 1 to projection, and 2 projections in often pair of projection are bent to form buckle 5 all relatively, and the leg 4-3 of profiled strip 4 withstands in buckle 5; Such design, can prevent strip 2 from moving.The length of the clinch 3 of strip 2 is 40-300mm, and namely the connecting length of adjacent strip 2 is 40-300mm.
Certainly, just combine above
accompanying drawingthe preferred embodiment of the present invention's (invention) is described in detail; the practical range of the present invention's (invention) is not limited with this; the equivalence change that all principles according to the present invention's (invention), structure and structure are done, all should be covered by the protection domain of the present invention's (invention).
