Replacement unloading structure and construction method for vertical component

Abstract

The invention discloses a replacement unloading structure and construction method for a vertical component. The replacement unloading structure comprises support components fixedly mounted at the upper end and the lower end of the replaced vertical component; unloading columns positioned on the two sides of the vertical component are arranged between the support components; an unloading jack is arranged between the unloading columns and the support component at the upper end. According to the replacement unloading structure disclosed by the invention, the two support components are arranged on the upper and lower sides of the component required to be replaced, then the unloading columns and the unloading jack are arranged, and the vertical component is used as a benchmark, loads required to be unloaded are transmitted to the vertical component through the upper support component, the unloading jack, the unloading columns and the lower support component; compared with a conventional replacement technology, the replacement unloading structure has the advantages that the occupied space is less, original space can be rapidly recovered after replacement, the construction period is shortened, the cost is reduced greatly, and obvious social benefits and economic benefits are realized.

Description

technical field [0001] The invention relates to the construction field, in particular to a replacement and unloading structure and a construction method of a vertical component. Background technique [0002] With the rapid development of the construction industry, problems with the concrete strength of structural components in construction projects occur from time to time. Once the concrete strength of the vertical structural components (columns, shear walls) of the building structure has problems, the economic and social impact will be huge. At present, there are usually three methods to solve such problems: one is to directly reinforce the problematic components, such as enlarging the cross-section, reinforcing steel sections, etc. Using such methods will change the stress distribution of the original structure and affect the building space; two. It is directly demolished and then re-cast. In view of the quality of the concrete, it is generally discovered after the formwor...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to solve the problems of changing the stress distribution of the original structure in the vertical component replacement method in the prior art, affecting the building space, high cost, and long construction period, and to provide a replacement and unloading structure for vertical components and a construction method , to achieve the purpose of fast and reliable replacement
