Problems solved by technology

But there are also the following disadvantages: 1) The ring stiffness of the circular single-wall corrugated pipe is poor; 2) The contact surface between the circular single-wall corrugated pipe and the pipe wall is small, resulting in a weak connection between the two and reducing the overall bending strength of the pipe

Embodiment 1

[0020] Example 1: as Figure 1 to Figure 5 As shown in the figure, a single-wall corrugated pipe as a hollow reinforcing rib of a structural wall pipe material in this embodiment includes a pipe body 1, and a plurality of corrugated protrusions 11 arranged at uniform intervals are formed on the pipe body 1. The corrugated protrusions The cross section of the starting 11 is circular, elliptical or polygonal. The pipe body is made by one-time molding.

[0021] Preferably, the corrugated protrusions 11 protrude toward the inner side wall of the pipe body 1 .

[0022] Preferably, the corrugated protrusions 11 are foldable and expandable. The corrugated protrusions can ensure the flexible bending of the pipe body at a relatively large angle without internal stress.

[0023] Preferably, the cross section of the pipe body 1 is oval or polygonal.

[0024] Further, the pipe body 1 is made of a mixed material of PP, PE, EVA, PVC, ABS, plastic and glass fiber material.

Abstract

The invention relates to a single-wall corrugated pipe serving as a hollow reinforcing rib of a structural wall pipe. The single-wall corrugated pipe comprises a pipe body, wherein a plurality of corrugated protrusions which are evenly arranged at intervals are formed on the pipe body, and the cross sections of the corrugated protrusions are in a circular shape, an oval shape or a polygon shape. Due to the corrugated protrusions on the pipe body formed at one time, the corrugated pipe can be flexibly bent at a large angle without internal stress; moreover, the ring stiffness of an outer corrugated winding structure wall pipe is improved, and the overall bending strength is improved; and the contact area between the single-wall corrugated pipe and the wall pipe is increased, the stability of the pipe body is improved, and then the connecting strength between the hollow reinforcing rib and the wall pipe is improved. The whole single-wall corrugated pipe solves problems in the prior art,and the structure is firmer and stabler.

Description

technical field [0001] The invention relates to a single-wall corrugated pipe as a hollow reinforcing rib of a structural wall pipe. Background technique [0002] In the production of outer corrugated winding structure wall pipes with hollow stiffeners, a single-wall corrugated pipe with a circular cross-section is generally used as the hollow stiffener, mainly because the circular single-wall corrugated pipe can be bent in any direction. However, there are also the following disadvantages: 1) The ring stiffness of the circular single-wall corrugated pipe is poor; 2) The contact surface between the circular single-wall corrugated pipe and the pipe wall is small, resulting in a weak connection between the two and reducing the overall bending strength of the pipe. Therefore, it is necessary to provide a new type of single-wall corrugated pipe to overcome the above disadvantages. SUMMARY OF THE INVENTION [0003] The present invention aims to solve the above-mentioned proble...
