Problems solved by technology

[0005] In the structure described in the above-mentioned patent application, although the ribs are designed as steel strips, which increases the strength of the pipe, only the overlapping parts are designed at the junction, so that When welding, the joint needs to be fixed before welding. If the welding is not firm, it is easy to crack and leak.
[0006] And the structural steel strip is embedded in the ribs in a sheet shape, which will affect the ring stiffness of the entire pipe due to the destruction of the ribs

Embodiment Construction

[0034] The implementation of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0035] attached Figure 4 to attach Image 6 It is the embodiment 1 of the plastic-steel winding pipe strip of the present invention.

[0036] The strip body includes a base plate 30 and vertical reinforcing ribs 40 (ie rib plates). The reinforcing rib 40 includes a vertical metal reinforcing rib 401 and a plastic layer 402 covering the vertical metal reinforcing rib 401 . In this embodiment, the plastic material is polyethylene, and the metal material is steel strip. The cross-section of the vertical metal reinforcing ribs 401 is an inverted T-shaped cross-section. The shape of the reinforcing rib 40 is a hemispherical head.

[0037] The two ends of the tape and the overlapping parts of the adjacent tape are respectively the protruding platform 31 and the protruding boss 32 (that is, the engaging protrusion). The joint surface protruding ...

Abstract

The invention discloses a steel belt reinforced composite lap joint belt material for a plastic-steel wound pipe. The belt material at least comprises a belt material unit, wherein the belt material unit comprises a substrate and at least one rib plate; the rib plate is arranged vertical to the substrate; a steel belt is arranged on the rib plate; the rib plate is connected to the substrate; and one side of the substrate is provided with a joint part which has a flat structure and is at least provided with a joint bump. The design mode of an occlusal surface is provided, so that belt materials are jointed more stably and reliably, a weld face is prevented from cracking, and welding intensity and the quality of a tubular product are ensured.

Description

technical field [0001] The invention relates to a plastic-steel winding pipe, in particular to a plastic-steel winding pipe strip. Background technique [0002] Spiral wound pipes can be produced by special or general winding equipment using plastic or plastic-steel composite plates, strips, pipes and profiles. As a winding pipe for gravity self-flowing liquid transportation, the main focus is on its ability to withstand external pressure or impact. Therefore, the use of various structural wall pipes can achieve the purpose of reducing production costs by saving materials while maintaining the same performance indicators. [0003] The plastic-steel composite material uses a steel strip with a modulus of elasticity much higher than that of plastic as the reinforcing rib of the pipe. It combines the advantages of steel and plastic materials, which can effectively reduce the amount of plastic used and further reduce costs. The application date is that Chinese patent 200520112...
