Abstract
The utility model provides a section for a large-caliber plastic steel strip composite corrugated wrapped pipe. The section is composed of basal plastic (5), and a steel strip (1) with holes, plastic (2) and plastic (3) on the basal plastic (5). When the section is used for spirally wrapping into a corrugated wrapped pipe, the left and the right ends of the section are overlapped, and a large-caliber plastic steel strip composite corrugated wrapped pipe which is wrapped by the section is a large pipe produced by a small machine. Technology is easy to control, manufacture is simple and convenient, and the wrapped large-caliber plastic steel strip composite corrugated wrapped pipe has the advantages of high compressive strength, favorable sealing and anti-leakage performances, material saving and low cost. The utility model is mainly used for metro push pipes, the repair of cement ducts, pipes for supplying and draining water, preventing chemical corrosion, discharging flood, irrigating farmland and guiding and conveying water in a long distance, and the pipes for conveying oil and gas.
Description
Technical field
The utility model relates to a kind of large diameter pipeline section bar, and more particularly, it relates to a kind ofly carries out the composite corrugated enwound tube section bar of large-bore plastics steel band that physics is composited with plastics and steel band.
Background technique
At present, sell various multiple tubes on the market, as: aluminium-plastic composite pipe, plastic steel composite pipe, though these composite pipes have solved the corrosion-resistant and not enough weakness of plastic tube stiffness of metallic material, bigger improvement and breakthrough are arranged, but they all are to make and use at small-bore scope wind on the pipeline industry.Up to the present, on market, do not see as yet and both solved anticorrosive metal, solve the heavy caliber plastic-steel composite winding pipe of plastics insufficient strength again.
Summary of the invention
The purpose of this utility model is to overcome deficiency of the prior art, provides a kind of simple in structure, utilizes small machine production to be easy to manufacturing, has both solved anti-corrosion of metal, solves the not enough composite corrugated enwound tube section bar of large-bore plastics steel band of plastics hardness again.
Large-bore plastics steel band composite winding pipe section bar of the present utility model comprises spirogyrate with holes steel band and the plastics of outer wall through the burr of roll extrusion formation.The steel band section bar of this plastic overmold is wound in the composite corrugated entwining tube of large-bore plastics steel band through spiral, be plastics around the composite corrugated enwound tube section bar of described heavy caliber steel band, in the middle of the real wall of section bar spirogyrate is steel band with holes, the effect of plastics is anticorrosion, and the effect of steel band is the demeanour that increases after section bar is wound in tubing.Evagination section bar base part is the plastic wall that extrusion molding is shaped.
The beneficial effects of the utility model are:
(1) with the big tubing of small machine production;
(2) reliability height, corrosion protection, good, the long service life of demeanour;
(3) simple in structure, be easy to make;
(4) remains of the deceased structure, economical with materials, cost is low.
Description of drawings
Fig. 1 is the sectional view of the steel band with holes of two cornice burrs of process roll forming before the composite corrugated enwound tube section bar of large-bore plastics steel band of the present utility model is shaped.
Fig. 2 is the stereogram of the steel band with holes of process roll extrusion two cornice burrs before the composite corrugated enwound tube section bar of large-bore plastics steel band of the present utility model is shaped.
Fig. 3 is the structural drawing of the section bar after the composite corrugated enwound tube section bar of large-bore plastics steel band of the present utility model coats through extrusion molding.
Embodiment
The utility model will be further described below in conjunction with accompanying drawing.
In the drawings, the composite corrugated enwound tube section bar of large-bore plastics steel band mainly is made up of steel band with holes (1) section bar and plastics (2), plastics (3), plastics (5), plastics connect into hollow structural section by steel band tie point with holes (6) with ripple overlay film steel band with holes (1) and plastic board (5), this structural shape is carried out spiral when being wound in the ripple entwining tube, and overlap joint back, section bar two ends is located to weld at tie point (4).
The burr of the composite corrugated enwound tube section bar steel of described large-bore plastics steel band (1) both sides for forming through roll extrusion.Purpose is exactly the adhesion that solves plastics and steel band by physical method, coats steel band with holes (1) through extrusion molding and forms the big mouthful of composite corrugated enwound tube section bar structural drawing 3 of plastics steel band of the present utility model.In this structural drawing, (1) is steel band with holes, coats by extrusion molding steel band with holes and plastics are linked together.(5) be the monoblock plastic board of extrusion plastic by steel band tie point with holes (6) formed thereby, plastics make plastics and steel with holes and plastics (5) be linked to be an integral body through steel band with holes, solved the connection of two kinds of materials, the steel band overlap joint weld when (4) supply spiral to be wound in the ripple entwining tube for reserving.
Described Fig. 3 twines two ends, the left and right sides steel band that makes this section bar and locates an overlap joint in (4) through spiral, between overlapped points (4) is located by steel band
The weldering of argon fluorine connects carries out the welding of roller type argon fluorine, by extrusion molding steel band phase lap-joint is coated again, and the plastics that this time extruded are with the steel band inner-walls of duct with holes and the outer wall filled plastics of weld.Described steel band hole is that extrusion molding connects by the steel band hole, plays rivet clasp, solves the physical connection of plastics and steel band effectively, and the two is securely connected together, and solves the connection of two kinds of different materials.
Claims (3)
1. composite corrugated enwound tube section bar of large-bore plastics steel band, by bottom plastic (5) and on steel band with holes (1), plastics (2) and plastics (3) form, it is characterized in that: ripple steel band (1) section bar of overlay film plastics is carried out spiral when being wound in the ripple entwining tube, in the middle of this winding tube wall is ripple steel band with holes, is plastic overmold around the steel band.
2. the composite corrugated enwound tube section bar of large-bore plastics steel band according to claim 1 is characterized in that: the both sides of ripple steel band with holes (1) are that plastics (2) and plastics (3) coat.
3. the composite corrugated enwound tube section bar of large-bore plastics steel band according to claim 1 is characterized in that: the bottom of ripple steel band with holes (1) is a plastic board (5).
