Abstract
The utility model relates to a double-flat wall composite plastic steel winding pipe which comprises a pipe formed by winding a plastic strip; reinforcing ribs of which the sections are T-shaped are arranged on the outer surface of the plastic strip; a folding steel plate is additionally arranged in a space between the two adjacent reinforcing ribs, the section of the folding steel plate is U-shaped, and the folding steel plate extends towards the two sides respectively to from an auxiliary plate and is buckled on the outer surface of the plastic strip; the outer ends of the two auxiliary plates lean against the corner positions of the T-shaped reinforcing ribs; and a flat plate protective layer is enwrapped at the outer side of the pipe. The double-flat wall composite plastic steel winding pipe has the beneficial effect that through improving the forming structure of the pipe, the purposes of improving the rigidity of the pipe and eliminating the belt collapse phenomenon are achieved.
Description
Technical field
The utility model relates to plastic-steel-wound tubing technical field, specifically a kind of two flat walls 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, and preparation process is more complicated also.
The model utility content
The purpose of this utility model is to provide a kind of two flat walls 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 two flat walls 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 corner that the outer end of two accessory plates is resisted against the strengthening rib of T shape coats the dull and stereotyped protective layer of one deck in the outside of described tubing.
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.
Connect by staggered bonding interface between the strengthening rib of described dull and stereotyped protective layer and T shape, form the entwining tube that inside and outside wall is smooth.
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:
One, the combination of batch production production and field-winding
Because the production of this product belongs to the post forming winding process, have with the comparative advantages of common heavy caliber two flat walls plastic-steel spirally-wound pipe: but that 1 Assembling is made is bonding, can save the part freight.2, twine the tubulation process for fastening and bonding, solved because of inside and outside wall fusion temperature difference in the post forming process and caused the body quality problems.3, solved the problem that reject rate descends.
Two, good effect
The utility model has overcome the deficiency of Double-flat wall steel plastic composite winding pipe product fully, receives on the coefficient basis, place taking into full account same sex material heat, and Applicable scope all can ensure the quality of product and use safety under ± 60 ℃ of condition.
Aspect economic benefit, this novel tube relatively has the following aspects active factor with the Double-flat wall steel plastic composite winding pipe: 1, energy saving, reduce energy consumption.Producing the equal standard tubing of specification of the same race, energy saving power 20%, water 10%, cost of labour 30%, raw material 15%, reject rate reduces by 18%.2, aspect production technology, because the difference of structure, the quality of product of my company is more stable, has ensured working life.
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 dull and stereotyped protective layers, 4 staggered interfaces.
Embodiment
Such as Fig. 1～shown in Figure 2,
A kind of two flat walls 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, folding steel plate 2 and dull and stereotyped protective layer 3.
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 bonding interface connection, 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 12 in twos, the cross section main body 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 22 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.Folding steel plate plays the effect of stiffening rib herein, and the section configuration of folding steel plate has expression in Fig. 2, for reference.
Coat the dull and stereotyped protective layer 3 of one deck in the outside of tubing; this flat board protective layer is the same with plastic strap all to be the band of PE extruding and moulding; and pass through staggered interface 4 bonding connections between the strengthening rib of dull and stereotyped protective layer and T shape; and can connect by mode bonding or that heat seal connects, form the entwining tube that outer wall is smooth.
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.
