Problems solved by technology

[0003] 1. When the diameter of the pipe is large and the ring stiffness is high, the height of the strip reinforcement rib is high, and it is easy to appear when the strip is wound into a pipe and bent. image 3 The ribs shown are lodging, and the degree of lodging will become more and more severe with the release of the residual stress generated when the strip is bent. Once this happens, the ring stiffness performance of the pipe will be difficult to guarantee
[0004] 2. Due to the thin metal strips in the reinforcement ribs, the pipes are prone to cracks in the plastic at the top of the reinforcement ribs to expo

Embodiment Construction

[0022] Figure 4 Shown is a steel-plastic composite strip of the present invention, which is composed of a plastic flat belt 1, a reinforcing rib 2 and a composite inside the reinforcing rib Type reinforced steel belt 3 is constituted. The reinforcing ribs 2 are perpendicular to the plastic flat belt and are distributed equidistantly. An edge-folded overlap structure is provided on one edge of the plastic flat belt 1, and the folding direction must be consistent with the top edge of the reinforcing rib 2.

[0023] Figure 5 Shown is another embodiment of the steel-plastic composite strip of the present invention, which is similar to Figure 4 The only difference shown is that the reinforced steel strip compounded in the rib is of the "[" type.

[0024] Image 6 Shown is a steel-plastic composite drainage pipe of the present invention. The pipe is made of Figure 4 The strip shown is wound, extruded and welded. It consists of a pipe body 4 with a uniform wall thickness perpendicula...

Abstract

The invention provides steel-plastic composite strips and steel-plastic composite drainage tubing manufactured by the same. The strip structure consists of a plastic flat strip and a reinforced rib which extends out vertically from the flat strip surface, forms into a whole with the flat strip and is provided with a crimped top end. The reinforced rid is compounded with a reinforced steel strip having two crimped ends. The tubing structure comprises a plastic tube with even wall thickens and a reinforced rib, wherein the reinforced rib is integrated with the tube, is spirally wound on the outer wall of the tube at an equal space, and is in a vertical crimped shape.

Description

Technical field [0001] The invention relates to a steel-plastic composite strip, in particular to a steel-plastic composite strip with a special-shaped reinforced steel strip and a steel-plastic composite drainage pipe made from the steel-plastic composite strip. technical background [0002] It has become a well-known technology to use various forms of plastic strips or profiles to produce large-diameter plastic pipes by winding molding. Similar products include hollow winding plastic pipes, winding corrugated pipes, and reinforced pipes. In order to improve the ring stiffness of the large-diameter wound plastic pipe and reduce its production cost, in recent years there has also been a technology of using metal-reinforced plastic strips to produce metal-reinforced plastic pipes. ZL200520112528.4 discloses a metal reinforced plastic strip and a metal reinforced plastic drainage pipe made from it, such as figure 1 , figure 2 As shown, but the strip and pipe have the following def...
