A hoop welding reinforcement method for circular steel structural members

Abstract

The invention discloses a hoop welding reinforcement method for a circular tube steel structural member. The original structure, that is, the circular tube steel structural component, is processed, including the following steps: 1) Anti-corrosion treatment is performed on the surface of the original structure, and solvent-free epoxy resin is applied. paint, after the paint film is dry, carry out acrylic polysiloxane topcoat brushing; 2) make the ring plate, the ring plate is evenly arranged along the length direction of the original structure; 3) make the sleeve, the sleeve is embedded Between two adjacent ring plates, the casing is two sets of half-split casings, the two half-split casings are spliced ​​and outsourced on the outside of the original structure, and a cavity is left between the original structure; the two half-split casings The two ends of the split casing are welded to the ring plate through full penetration welding. After the two ends are welded to the ring plate, the butt joint of the half split casing is welded with a full-length weld. The present invention adopts the process of outer cladding of round steel pipes instead of dismantling the original structure, ensuring the safety and stability of the original structure during reinforcement.

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 ...
