Frame column replacement and reinforcement construction method

Abstract

The invention relates to a frame column replacement and reinforcement construction method, and belongs to the technical field of completed building structure repair. The frame column replacement and reinforcement construction method comprises the steps of firstly, correspondingly arranging supporting steel columns in the four directions of to-be-replaced frame columns of the layer and the four directions of upper and lower frame columns, and arranging jacks between the supporting steel columns and beam bottoms; then removing all the to-be-replaced frame columns, wherein the tops are removed to the upper ground; then installing a column formwork, wherein the top of the column formwork is designed to be a horn mouth formwork higher than the upper ground; then pouring concrete and curing from the horn mouth formwork on the upper layer; and finally, removing the formwork and the supporting steel columns. The method has the advantages of advanced construction process, high construction technical content, high operability, close procedure connection and fast construction progress, the construction cost is reduced while the construction quality is guaranteed, obvious economic benefits are generated, and the method is worthy of application and popularization.

Description

technical field [0001] The invention belongs to the technical field of building construction, in particular to a method for repairing a constructed building structure, in particular to a frame column replacement and reinforcement construction method. Background technique [0002] With the rapid development of housing construction and infrastructure construction in my country in recent years, the supply of commercial concrete used in concrete building structures has increased year by year, but the raw materials of commercial concrete, such as cement, gravel, sand, etc., are restricted in mining and supply, and the quality of raw materials is increasing year by year. This has directly led to frequent outbreaks of construction in progress in recent years because the concrete strength does not meet the requirements. What's more, the 16-story building that has been built has to be demolished due to insufficient concrete strength. [0003] In the specific construction process, ther...

[0002] With the rapid development of housing construction and infrastructure construction in my country in recent years, the supply of commercial concrete used in concrete building structures has increased year by year, but the raw materials of commercial concrete, such as cement, gravel, sand, etc., are restricted in mining and supply, and the quality of raw materials is increasing year by year. This has directly led to frequent outbreaks of construction in progress in recent years because the concrete strength does not meet the requirements. What is more, the 16-story building that has been built has to be demolished due to insufficient concrete strength.

[0003] In the specific construction process, there may be such a problem, that is, when constructing the multi-storey frame structure on the ground, when the construction reaches a certain high level, it is found that the concrete strength of the frame structure column of a certain low level below it does not meet the requirements. At that time, the formwork support system of the next layer and the upper layer of the layer had been removed, so how to repair the frame columns whose concrete strength did not meet the requirements of the layer has become an urgent problem in this field. problem
