Abstract
The utility model provides a tube with a novel structure and particularly relates to a U-shaped reinforcing rib single wall winding tube. The U-shaped reinforcing rib single wall winding tube is formed by a strip in a spirally winding and thermally welding mode. At least one U-shaped reinforcing rib protruding outwards is inlaid in the strip and a trapezoid cavity is arranged at the inner side of the reinforcing rib. Compared with the structure of a traditional reinforcing rib which is a steel strip vertical rib, the U-shaped structure of the U-shaped reinforcing rib single wall winding tube is high in intensity and capable of reducing using amount of polyethylene (PE) materials. Meanwhile, due to the fact that the trapezoid cavity is arranged at the inner side of the reinforcing rib, the using amount of the PE materials is reduced to a maximum degree. The U-shaped reinforcing rib single wall winding tube achieves maximization of tube intensity under the condition of the same material using amount.
Description
Technical field
The utility model relates to the drainage pipe that uses in a kind of municipal engineering, specifically a kind of U-shaped stiffening rib single wall wrapped tube.
Background technique
The main feature of polyvinyl plastics tubing be in light weight (its unit weight only for steel pipe 1/8), easy construction; Tube wall is highly polished, and fluid resistance is little, and is less scaling; Corrosion-resistant, characteristics such as long service life are that country widelyd popularize a kind of product of application in recent years.But because polyvinyl piping materials self, make that the tubing rigidity is lower, reach the ring stiffness that usage requirement must increase tubing by the method that increases wall thickness, the big increase of materials of Here it is tubing.So common way is to set up steel rib stiffening rib at the outer surface of tubing, the pattern of at present common stiffening rib is vertical steel band, and there is easily the problem of muscle in the stiffening rib of this structure.
The model utility content
The purpose of this utility model is to provide a kind of U-shaped stiffening rib single wall wrapped tube, by optimizing the structure shape of wrapped tube, reaches and improves the tubing ring stiffness under the equal materials situation, reduces the purpose of tubing cost.
The technical scheme in the invention for solving the technical problem is: a kind of U-shaped stiffening rib single wall wrapped tube, twining also by the band spiral, thermal weld forms, it is characterized in that, be inlaid with at least one stiffening rib of the U-shaped of projection laterally in the described band, and be trapezoidal cavity in the inboard of described stiffening rib.
Described stiffening rib is rolled steel strip.
Be inlaid with two stiffening ribs parallel to each other in the described band.
The inside and outside both sides of described stiffening rib all are provided with the PE anticorrosive coat.
The beneficial effects of the utility model are: be the pattern of the perpendicular muscle of steel band with respect to traditional stiffening rib, the structure of the U-shaped in this structure has higher intensity, can reduce the consumption of PE material, the inboard of stiffening rib is trapezoidal cavity simultaneously, farthest reduces the consumption of PE material.Realized the maximization of the tubing rigidity under the equal materials situation, a kind of pipeline configuration of new structure is provided.
Description of drawings
Fig. 1 is stereogram of the present utility model;
Fig. 2 is whole-cutaway view of the present utility model;
Fig. 3 is A place partial enlarged drawing;
Among the figure: 1 band, 2 stiffening ribs, 3 cavitys, 4 anticorrosive coats.
Embodiment
As Fig. 1, Fig. 2, shown in Figure 3,
A kind of U-shaped stiffening rib single wall wrapped tube is that band 1 wherein is the plastic-steel band of extruding and moulding, is inlaid with the stiffening rib 2 of the U-shaped of projection laterally in band 1 by the tubing that band twines in a spiral manner and thermal weld forms, and stiffening rib is cold-rolled strip.The two ends of stiffening rib are embedded in the band, form one, and this stiffening rib also is the one extrusion moulding.And be trapezoidal cavity 3 in the inboard of stiffening rib, all be provided with PE anticorrosive coat 4 in the inside and outside both sides of stiffening rib, this structure can guarantee farthest that materials are economized, the intensity height.Be inlaid with two stiffening ribs parallel to each other in the best band, also can be for single or a plurality of.
In the process of making, at first make the stiffening rib of U-shaped, by the mode of extruding and moulding stiffening rib and one in PE material are extruded by mould then, form more integrated band, form pipeline by winding formation volute and hot weld at last and get final product.
Except the described technical characteristics of specification, be the known technology of those skilled in the art.
Claims (4)
