Description
【Technical field】
The present invention relates to a kind of plastics reinforcements to wind bellows, is a kind of buried tubing, is widely used in various drainpipes
Road is laid with.
【Background technology】
China Patent No. is ZL 201220119995.X, and the internal-rib enhancing spiral of a kind of entitled band and its preparation twines
Disclose a kind of band around the patent of tubing, including panel, arc body and stud, the arc body be located at the outside of panel and
A cavity is formed between the panel and arc body, in cavity of the stud between arc body and panel and by cavity one
It is divided into two, the two sides of the panel are clinch.Panel, arc body and stud in the band are through being once extruded into
Type.Tubing body is the tubular body formed by the band through winding and melting welding, and the arc body is in tubing body
Outside forms outer corrugated shape, and is connected to pipe fitting in the both ends plastic welding of tubing body.
Above-mentioned band and its internal-rib enhancing spiral winding tubing of preparation possess following defect：
1st, due to extrusion molding be with hollow and overlap edge band, cause produce band when hollow cavity in
Heat can not discharge, along with the clinch and stud on both sides need to be molded, so the speed for producing this band can be very slow, nothing
Method realizes real benefit.
2nd, since band is tubing that is first preforming, being then welded into the both sides overlap joint of the band of cold conditions, tubing overlaps
Portion is most weak place and is the outside for being exposed at tubing, and climate temperature, transport and the variation of installation influence very big, overlap joint
Portion's tensile strength is inadequate, it is easy to be broken, ripple is in spring-like.
China Patent No. is：201110121186.2 entitled internal rib reinforcing outer ripple type plastic twining structured wall pipe
And its patent of manufacturing method discloses a kind of internal-rib enhancing ripple type plastic winding structural wall tube, which had by both sides
The plastic shaped band for having the tubular lobes for including hollow cavity is helically wound and fuses to form tubing body through melten gel, with
Two hollow cavities adjacent to each other form hollow reinforcement after fusion between the adjacent plastic shaped band of spiral way winding
Muscle, and fuse position in the middle part of hollow reinforced rib and form upright enhancing internal-rib, the tubing body includes cylindrical wall, spiral shell
Rotation is around hollow reinforced rib on it and the enhancing internal-rib perpendicular to tube wall in hollow reinforced rib, the enhancing internal-rib
The hollow reinforced rib is divided into two hollow cavities arranged side by side, the faying face of fusion is located at the enhancing internal-rib.The tubing be by
The plastic shaped band that both sides have the tubular lobes for including hollow cavity is helically wound and fuses to be formed through melten gel, with spiral shell
Two hollow cavities adjacent to each other form hollow reinforced rib after fusion between the adjacent plastic shaped band that rotation mode is wound,
And it fuses position in the middle part of hollow reinforced rib and forms upright enhancing internal-rib.
Above-mentioned internal rib reinforcing outer ripple type plastic twining structured wall pipe and its manufacturing method possess following defect：
1st, its face of weld is circumferential entire section, causes the ring stiffness of structure-wall pipe material to reduce, once technology controlling and process is not
When then easily causing drawing pipe insufficient strength, it is easy to be broken, ripple is in spring-like.
2nd, the material of its used melten gel and the material of tubing have differences, the difference of the tensile strength of two kinds of materials,
Hot melt strength can be caused to reduce, influence the ring flexibility of structure-wall pipe material.
3rd, its enhancing internal-rib is fused by melten gel forms, and causes the width for enhancing internal-rib that cannot unify, i.e. total wall pipe
The ring stiffness of material cannot be guaranteed, and the rice of tubing increases again.
【The content of the invention】
