Welding reinforcing method for hoop of circular tube steel structural member

Abstract

The invention discloses a welding reinforcing method for a hoop of a circular tube steel structural member. The method is used for processing an original structure, namely a circular tube steel structural member and comprises the following steps that firstly, preservative treatment is carried out on the surface of the original structure, the surface is coated with solvent-free epoxy resin paint, and after a paint film is dry, coating of crylic acid polysiloxane finishing coat is carried out; secondly, annular plates are manufactured and are evenly arranged in the length direction of the original structure; thirdly, casing pipes are manufactured and embedded into the every two adjacent annular plates, and the casing pipes are two sets of semi-cut casing pipes; the two semi-cut casing pipesare spliced to wrap the outer side of the original structure, and a cavity is reserved between the semi-cut casing pipes and the original structure; and the two ends of the two semi-cut casing pipes are welded to the annular plates through full penetration welding, and after welding between the two ends of the two semi-cut casing pipes and the annular plates is completed, close welding of a full welding line is carried out on a joint of the semi-cut casing pipes. According to the welding reinforcing method, dismantling of the original structure is replaced by a circular steel tube outer wrapping process, and safety and stability of the original structure in the reinforcing process are ensured.

Description

technical field [0001] The invention belongs to the technical field of building construction, and in particular relates to a hoop welding reinforcement method for a circular pipe steel structural component. Background technique [0002] A batch of venues in the 1990s can no longer meet the functions of the new era. If they are all demolished and newly built, it will be detrimental to environmental protection and cost. Therefore, the technical transformation of large venues has become the mainstream, and the reinforcement of the original steel structure of pipe truss is a difficult point. In particular, the decorative effect of the exposed components should also be considered, and the relevant construction procedures should not damage the original components. The reinforcement of these circular tube components has become a difficult problem. Contents of the invention [0003] Purpose of the invention: The purpose of the invention is to address the deficiencies of the prior ...
