Abstract
The utility model relates to a steel plastic composite wound pipe, which is spirally wound by a sheet (1) with a U-shaped cross section; a U-shaped steel strip (2) is arranged in the sheet (1) with the U-shaped cross section; the U-shaped steep strip (2) is contained in a plastic film layer (3); step-shaped lap joint wings (4) and (6) extend from the bottom part of the sheet (1) with the U-shaped cross section to the left side and the right side; a bulge (5) and a groove (7) are respectively arranged on the left lap joint wing and the right lap joint wing, and the bulge (5) of the left lap joint wing (4) is tightly pressed into the groove (7) of the adjacent right lap joint wing (6). The steel plastic composite wound pipe has the following advantages: as the bottom edge of the U-shaped steel strip and the outer surface of the pipe are tightly pressed together, the strength of the steel plastic composite wound pipe is enhanced, and the contact area between the steel pipe and the pipe wall is larger. As two vertical reinforcing ribs erected on the U-shaped steel strip are connected into a whole, the steel plastic composite wound pipe is difficult to bend and tilt. The adjacent two lap joint wings of the sheet with the U-shaped cross section are tightly pressed together, thereby having higher pipe strength, better durability and better sealing property at an interface.
Description
Technical field
The utility model relates to a kind of tubing, especially a kind of steel plastic composite wound pipe.
Background technique
Patent 200820199829.9 discloses a kind of steel plastic composite wound pipe.This entwining tube is provided with U-shaped steel band stiffening rib in the tube wall of hollow material, described U-shaped steel band stiffening rib opening is outside the entwining tube pipe.This its intensity of steel plastic composite wound pipe with steel band stiffening rib, rigidity are all than common entwining tube height, because the shielding action of steel band makes its impact resistance, are difficult for perforation.But because this kind steel plastic composite wound pipe is to twine the formation tube wall continuously with hollow material, hollow material connects by the mutual hot melt in side.Like this, the quality of tubing depends on the quality of the weld seam that forms, in case these must cause whole tubing to lose efficacy through a certain local cracking that occurs of the welded seam of whole structural pipe wall.Because whole tubing all is entwined by hollow material, the tube forming material requested is many, the cost height in addition.
Patent 03233681.0 discloses another helical fissure plastic tube, and this plastic tube is entwined by continuous solid wall pipe of one deck and outer convex rib reinforced structure spiral.Outer convex rib reinforced structure cross-pressure merges the position of stitching at each adjacent two overlap joint of formed continuous solid wall pipe.Like this, improved the withstand voltage and survivability of tubing.But the outer convex rib reinforced structure cross section of this kind tubing is the structure of opening curve form, and its opening direction is towards the center line of pipe, so the area of contact of outer convex rib reinforced structure and solid wall pipe is less, and after the long-time use wearing and tearing, steel band comes off easily.
The model utility content
The technical problems to be solved in the utility model is to overcome the deficiency of aforementioned tube, a kind of steel plastic composite wound pipe of innovation structure form is provided, it is " U " tee section that a kind of outer convex rib reinforced structure is provided, and its opening direction is back to the steel plastic composite wound pipe of pipe center line.
The purpose of this utility model is achieved through the following technical solutions: this steel plastic composite wound pipe is entwined by " U " tee section sheet material spiral.It is characterized in that: be provided with " U " shape steel band in " U " tee section sheet material, " U " shape steel band opening back to tube hub towards the entwining tube outside, " U " shape steel band is contained by plastic membranous layer, " U " tee section sheet material stretches out the stepped shaft overlap joint wing in both sides to the left and right by the bottom, about overlap joint be respectively equipped with projection and groove on the wing, the projection of the left side overlap joint wing closely is pressed in the groove of the adjacent right side overlap joint wing.Described projection and groove cross section can be triangle, trapezoidal, square, circular arc.The solid wall pipe that in steel plastic composite wound pipe, is entwined by strip sheet material spiral with one deck.The adjacent overlap joint fin pressing place outside is covered with plastic sheet.
Compared with prior art, the utlity model has following advantage: the steel plastic composite wound pipe that adopts this structure, because " U " shape steel band base is closely pressed together on tube outer surface, strengthened steel plastic composite wound pipe intensity, the area of contact of steel band and tube wall is also bigger, like this " U " shape steel band difficult drop-off.Two vertical stiffening ribs that " U " shape steel band is holded up are owing to connecting into an integral body, and are not flexible, tilt.The overlap joint fin of adjacent two " U " tee section sheet materials is closely pressed together on together, and tubing intensity is higher, and durability is better.Projection and groove on the overlap joint fin are closely pressed together on together, have increased the sealing of jointing.
