Special-shaped steel tube reinforcing ring installing and fixing structure and method

Abstract

The invention discloses a special-shaped steel tube reinforcing ring installing and fixing structure and method. The structure comprises a vertical supporting ring frame arranged on a special-shaped steel tube in a sleeving mode and a plurality of installation adjusting mechanisms, the installation adjusting mechanisms are evenly arranged on the side wall of the vertical supporting ring frame andare of a hollow structure, and supporting and positioning mechanisms penetrate through the installation adjusting mechanisms and are in butt-joint with the outer wall of the special-shaped steel tube.The method comprises the steps that firstly, three reinforcing ring positioning lines are drawn; secondly, a special-shaped steel tube reinforcing ring installing and fixing device is manufactured; thirdly, a first reinforcing ring is installed and fixed; fourthly, the special-shaped steel tube reinforcing ring installing and fixing device is loosened and disassembled; fifthly, a second reinforcing ring is installed and fixed; sixthly, a third reinforcing ring is installed and fixed; and seventhly, the special-shaped steel tube reinforcing ring installing and fixing device is disassembled. According to the special-shaped steel tube reinforcing ring installing and fixing structure and method, one installing and fixing structure is used for achieving installing and fixing of three reinforcing rings with different inner diameters, the positioning precision and the construction efficiency are high, installation deflection of the reinforcing rings is avoided, the welding quality of reinforcing ring butt-joint seams and angle welding seams is facilitated, and the labor intensity of workers can be effectively relieved.

Description

technical field [0001] The invention belongs to the technical field of installing and fixing a special-shaped steel pipe stiffening ring, and in particular relates to a structure and a method for installing and fixing a special-shaped steel pipe stiffening ring. Background technique [0002] The purpose of installing the stiffening ring on the pipe wall is to improve the rigidity of the pipe wall and increase the stability of the pressure steel pipe against external pressure. The production and installation of the existing steel pipe stiffening ring has become a bottleneck restricting the output of the steel pipe due to the large amount of assembly and welding work. In the assembly of stiffening rings, due to the standard size, the assembly is assembled sequentially after scribing, which can basically meet the requirements on site. When assembling the stiffening ring, it will be assembled into a wavy shape, resulting in unqualified external dimensions. It will also cause the...

[0002] The purpose of installing the stiffening ring on the pipe wall is to improve the rigidity of the pipe wall and increase the stability of the pressure steel pipe against external pressure. The production and installation of the existing steel pipe stiffening ring has become a bottleneck restricting the output of the steel pipe due to the large amount of assembly and welding work. In the assembly of stiffening rings, due to the standard size, the assembly is assembled sequentially after scribing, which can basically meet the requirements on site. When assembling the stiffening ring, it will be assembled into a wavy shape, resulting in unqualified external dimensions. It will also cause the seam of the stiffening ring to be misplaced, and the assembly error between the stiffening ring and the steel pipe will affect the subsequent welding construction, and the welding quality and production efficiency will be affected. varying degrees of influence
