Description
Technical field
The present invention relates to a kind of plastic-steel spirally-wound pipe, relate in particular to a kind of plastic-steel winding pipe belt material.
Background technique
The spiral winding pipe road can utilize plastics or compound plate, band, pipe and the profile shapes of plastic-steel to produce by special-purpose or general Wiring apparatus.As the entwining tube that flow by gravity liquid is carried, mainly pay attention to the performance that it bears external pressure or impact.Adopt various structured wall popes under the same performance index of maintenance, to reduce production costs thereby save material.
Plastic-steel is compound then with the steel band of Young's modulus superplastic far away strengthening rib as tubing, and the advantage that integrates steel, moulds two kinds of materials can effectively reduce quantity of plastics, further reduces cost.The applying date is that the Chinese patent 200520112528.4 on July 4th, 2005 discloses a kind of plastic-steel winding structure tube, as shown in Figure 1 to Figure 3, tubing 2 constitutes the smooth fluid passage of sealing by inner layer tube wall, and outer surface of tube wall is the solid straight rib structure of spiral surrounding.The manufacture method of described tubing 2 is to adopt the mode of extruding that polyvinyl plastics and steel band are combined into heterotypic strip 1, again band 1 is made tubing 2 by twining the form that overlaps and extrude welding.Band 1 comprises substrate 10 and fin 20, and fin 20 is a steel band, the outer polyethylene that evenly coats of steel band, and substrate 10 is a polythene material.Fin 20 is perpendicular to substrate 10.When above-mentioned band 1 was wound in plastic-steel spirally-wound pipe, substrate 10 promptly constituted tube wall, and fin 20 then is perpendicular to the outside spiral extension of tube wall.As shown in Figure 3, band 1 two ends are respectively stretches out platform 11 and stretches out boss 12, is that the platform 11 that stretches out that the end of band is located is engaged with the boss 12 ' that stretches out of adjacent tapes when twining overlap joint, and middle extruded stock with fusion carries out weld bonds to the mating face.
Therefore, the structural design of band is very crucial, need consider during design that following aspect requires: 1) guarantee the ring stiffness of tubing 2,2) be easy to Wrapping formed, broken band, 3) the junction firm welding, do not ftracture, non-leakage.In band 1 winding process, except that taking lap-welded production technology, also need to consider between the mating face of band 1 from structural design.Increase face of weld, increase weld strength, strengthen sealing.
The described structure of above-mentioned patent application though fin is designed to steel band, has increased the intensity of tubing, take the knot position but only designed, like this when welding, need could weld this joining portion is fixing at the joining portion, if not prison welding is easy to cracking, seepage takes place.
Summary of the invention
The purpose of this invention is to provide a kind of improved plastic-steel winding pipe belt material structure.This structure can form stable welded structure, and welding is firmly stable, can guarantee the quality of the tubing that forms.
Based on this, the technical solution of the utility model is achieved in that
A kind of steel belt reinforced composite belt material that is used for plastic-steel spirally-wound pipe, the band body comprises that substrate and at least one are perpendicular to substrate, and the strengthening rib that extends along the band length direction, and the strengthening rib on the band body is at least one, an end that it is characterized in that described substrate has the platform of stretching out, and stretches out platform and is provided with recess, and the other end of substrate then has the boss of stretching out, described stretch out boss can with the recess corresponding matching, to form stable locking mechanism.The width of band is also different, and the quantity difference of strengthening rib can guarantee the manufacturing efficiency of different tube diameters tubing like this.
Baseplate material is plastics, is provided with steel band in the described strengthening rib, and the strengthening rib fin is a steel band, the outer evenly coating plastic of steel band.Plastics can be polyethylene, polypropylene, PVC, and other plastic materialss that are suitable for.Strengthening rib fin material also can be other metallic material and Young's modulus and intensity other flexible materials much larger than plastics.The material higher to fusion temps such as PVC, faying surface can adopt bonding during winding.Steel band is shaped as a word, also can be I-shaped, T word and other shapes that is fit to.The profile of fin is the first word of hemisphere, also can be the shape that I-shaped, T shape etc. are fit to arbitrarily.
Described band, the winding overlapping part of its substrate two ends and adjacent tapes are respectively and stretch out platform or stretch out boss.The cylindric welding material of extruding is generally accepted by the mating face of stretching out boss, also can be accepted by the mating face of stretching out platform.The mating face of stretching out boss can adopt the slot of butt joint self-locking to transplant a cutting with the butt joint self-locking of stretching out the platform mating face to cooperate, locks firm, good seal, accurate positioning.The butt joint self-locking of stretching out platform is transplanted a cutting shape and can be perpendicular to substrate, and the turriform, T word, dovetail and other arbitrary shapes that is fit to that extend along the band length direction.
The recessed of form fit made and transplanted a cutting to the described butt joint self-locking slot that stretches out the boss mating face, is wider than the cylindric external diameter of extruding the welding material in the butt joint self-locking slot.Suitable gap is left in the side and the bottom surface that cooperatively interact between cutting and the slot, and can be designed to cooperate the inclined-plane, the mutual interference that the dislocation in the time of can eliminating the band overlap joint in winding process causes.Stretch out platform and stretch out the employing inclined-plane, overlap joint edge on the mating face of boss, the direction on inclined-plane (pressing the loading characteristic when twining pressing) is the inclined-plane evagination (needing pressing) that stretches out edge, platform mating face, stretch out the inclined-plane indent (needing tenon to close) at edge, boss mating face, make between the band to overlap firmly.When bearing external pressure or impacting, can come local stress relieving to concentrate weld cracking or the seepage that causes by resiliently deformable between the inclined-plane that tenon closes.Stretch out platform and the edge, mating face that stretches out boss also available inclined-plane overlap joint and other modes that is fit to.
The outer surface that stretches out boss can also be provided with strengthening rib, strengthens the intensity and the bearing capacity of junction, makes the joint weld joint not be re-used as main bearing position, thereby avoids stress to concentrate; Butt joint self-locking slot can overlap with this strengthening rib squelette with the center line that docks the self-locking cutting, also can slightly be offset.
The utility model adopts said structure, and the structure of joint is set in the end of band, and band can be fastened when welding, has stablized the processing structure of band, can guarantee the quality of processing of band, and the joining portion of band can not produce cracking or seepage phenomenon.
