Abstract

The invention discloses a method and equipment for reinforcing a concrete-filled steel tube column by sleeving concrete-filled steel tube. The method comprises the following steps: step 1, polishing and derusting the outer wall of the concrete-filled steel tube column to be reinforced by using an auxiliary device; secondly, two semi-rectangular steel plates prefabricated in advance are welded, so that the two semi-rectangular steel plates form a complete rectangular steel pipe, and the rectangular steel pipe is arranged outside the to-be-reinforced concrete-filled steel tubular column in a sleeving mode; and thirdly, the space between the outer wall of the to-be-reinforced concrete-filled steel tube column and the inner wall of the rectangular steel tube is filled with self-compacting concrete, and reinforcement is completed. The problems that an original circular concrete-filled steel tubular column cannot meet the use function requirement and the bearing capacity and rigidity of a component need to be greatly improved under the condition that the section shape of the component is not changed are solved, the bearing capacity and rigidity of the original circular concrete-filled steel tubular column can be greatly improved on the premise that the section shape is not changed, construction is convenient, and the construction cost is low. The economic benefit is obvious.

Description

technical field [0001] The invention relates to the field of building renovation, in particular to a method and equipment for reinforcing a concrete-filled steel tube column with a concrete-filled steel tube. Background technique [0002] At present, in construction projects, concrete-filled steel tubular columns are used as load-bearing components. Because steel pipes can work with concrete, the working conditions of steel pipes and concrete can be improved when they are under pressure. For steel pipes, since the pipes are filled with concrete, the pipes The stability of the wall under compression has been improved to a certain extent; for the core concrete, during the compression process, due to the constraint of the steel pipe wall, it is in a state of three-dimensional stress, which greatly improves the strength of the concrete. Therefore, the compressive bearing capacity of the entire CFST column is 1.5 to 2.5 times higher than the superimposed value when the steel tube...
