Abstract
The utility model relates to a single-wall composite plastic-steel winding pipe which comprises a pipe formed by winding a plastic strip, wherein reinforcing ribs with T-shaped cross sections are arranged on the outer surface of the plastic strip, a folding steel plate with a U-shaped cross section is additionally arranged in the space between every two reinforcing ribs, accessory plates extend out from two sides of the folding steel plate, the folding steel plate is buckled on the outer surface of the plastic strip, and the outer ends of the two accessory plates are propped against the turning points of the T-shaped reinforcing ribs. The purposes of increasing the rigidity of the pipe and eliminating the phenomenon of strip breaking are achieved through improving the forming structure of the pipe.
Description
Technical field
The utility model relates to plastic-steel-wound tubing technical field, specifically a kind of solid wall compound plastic-steel wrapped tube.
Background technique
Traditional two flat walls plastic-steel-wound tubing is widely used in the every field as municipal pipeline.Chinese patent for example: a kind of pressure pipeline with oversized caliber of announcing among the CN202140702U, pipeline are wherein twined by two kinds of bands and form, and namely adopting has steel band and without the formation of steel band cross winding.Although the wrapped tube of this kind structure also can solve the problem of load-bearing, but preparation process and canoe more complicated, and split easily at the splicing position of two bands each other, produce and collapse zoning, must increase thin film at outer surface and form enhancement layer, reduce the generation of collapsing band.And steel band is coated in the band, makes also more complicated.
The model utility content
The purpose of this utility model is to provide a kind of solid wall compound plastic-steel wrapped tube, by improving the shaping structure of tubing, reaches the rigidity that improves tubing, the purpose that zoning is collapsed in elimination.
The technical scheme in the invention for solving the technical problem is: a kind of solid wall compound plastic-steel wrapped tube, comprise by plastic strap and twine the tubing that forms, it is characterized in that, outer surface at described plastic strap is provided with the strengthening rib that the cross section is T shape, increasing by a folding steel plate in the space between the strengthening rib in twos, the cross section of described folding steel plate is U-shaped, and extend an accessory plate to both sides, folding steel plate fastener is combined on the outer surface of plastic strap, and the outer end of two accessory plates is resisted against the corner of the strengthening rib of T shape.
The plastic strap adjacent links together by the tight locking button overlap joint, and is provided with staggered bonding interface connection at the contact surface of lap-joint.
Folding surface of steel plate wherein has anticorrosive coat, moulds by crossing, the anticorrosion with painting material forms anticorrosive coat.
The strengthening rib quantity of the outer surface of described plastic strap is five, forms altogether four spaces, and in two spaces at middle part folding steel plate is set.
The beneficial effects of the utility model are: the two flat walls plastic-steel spirally-wound pipe has the outstanding behaviours of the following aspects:
This product has the outstanding behaviours of the following aspects
One, the combination of batch production production and field fabrication
1, solves the large-bore plastics volute because of structure problem, and caused externally under the load problem of stress distribution inequality.2, Placement is fastening and bonding, has overcome the large-bore plastics volute because in the easy problem that plastifies of fusion weld place polyethylene strip.
Two, good effect
Tradition large-bore plastics volute is because the defective that itself structure exists, the phenomenon that easily causes steel rib and PE band to break away from, affected the use of whole pipe-networks engineering, and this novel tube, taking into full account on the basis of above problem, although the cost of material than large-bore plastics volute increases to some extent, aspect the pipe-networks engineering safe handling, the constant product quality aspect of performance all improves a lot.Because the large-bore plastics volute is due to the defective of project organization existence, in tubing fusion weld process, PE band joint forms embrittlement, under load action, easily form fracture, so that tubing causes the uneven precipitation in road surface after the pipe-networks engineering backfill is complete, greatly affect the working life of pipe-networks engineering, caused bad social influence, and this novel tube has overcome the mass defect of the above product of large-bore plastics volute.
Description of drawings
Fig. 1 is sectional view of the present utility model;
Fig. 2 is partial schematic diagram of the present utility model;
Among the figure: 1 plastic strap, 11 tight locking buttons, 12 strengthening rib, 2 folding steel plates, 21 sidewalls, 22 accessory plates, 3 staggered interfaces.
Embodiment
Such as Fig. 1～shown in Figure 2,
A kind of solid wall compound plastic-steel wrapped tube comprises by plastic strap and twines the tubing that forms.Tubing is formed by spiral winding by plastic strap 1 and folding steel plate 2.
Outer surface at plastic strap 1 is provided with the strengthening rib 12 that the cross section is T shape, from the cross section, the both sides of plastic strap are respectively the tight locking button 11 that fastens usefulness, the plastic strap adjacent links together by the tight locking button overlap joint in the winding process, and the contact surface in lap-joint is provided with staggered interface 3 bonding connections, and can be undertaken by binder bondingly, form the inwall of a tubing.
Increasing by a folding steel plate 2 in the space between the strengthening rib in twos, the cross section of folding steel plate is U-shaped, on the corner be 90 degree, such two sidewalls 21 are completely perpendicular to the outer surface of plastic strap, and support strength is higher, and extend an accessory plate 22 to both sides, folding steel plate fastener is combined on the outer surface of plastic strap, and the outer end of two accessory plates is resisted against the corner of the strengthening rib of T shape, forms a triangular space, so just can form and strengthen supporting, improve the rigidity of tubing.Traditional steel rib is dull and stereotyped, and intensity is relatively low.Steel rib in the utility model is folding steel plate, and intensity is higher, and the section configuration of folding steel plate has expression in Fig. 2, for reference.Folding surface of steel plate wherein has anticorrosive coat, moulds by crossing, the anticorrosion with painting material forms anticorrosive coat, the working life that can improve pipeline.
In the present embodiment, the strengthening rib quantity of the outer surface of plastic strap is five, forms altogether four spaces, and in two spaces at middle part folding steel plate is set.The magnitude setting of folding steel plate wherein can reasonably dispose as required, and the quantity of folding steel plate is more, and the rigidity of tubing is larger, and cost is also higher.
Except the described technical characteristics of specification, be the known technology of those skilled in the art.
