Reinforced concrete column replacing and reinforcing method and device for unloading load of reinforced concrete column

Abstract

The invention provides a reinforced concrete column replacing and reinforcing method and a device for unloading the load of a reinforced concrete column, belonging to the technical field of buildings. The invention solves the problem that after the existing reinforced concrete column has a quality problem, the reinforcing and repairing works are relatively difficult. The reinforced concrete column replacing and reinforcing method mainly comprises the steps of material preparation, unloading, chiseling, erection of shuttering, replacement and removal of shuttering. The device for unloading the load of the reinforced concrete column comprises a supporting column which can be supported on the beam of the current layer, and hydraulic lifting mechanisms capable of lifting the supporting column are arranged at the two sides of the supporting column. The reinforced concrete column replacing and reinforcing method has the advantages that the original size of the column section can not be changed, and reinforcing traces can not be left. The device for unloading the load of the reinforced concrete column, which adopts hydraulic unloading, has the advantages of large applied force and uniform application of force.

Description

technical field [0001] The invention belongs to the technical field of buildings, and relates to a reinforced concrete column, in particular to a method for replacing and strengthening a reinforced concrete column and an unloading device for unloading the load of the reinforced concrete column. Background technique [0002] Concrete has been one of the main building materials since its inception, and the reinforced concrete structure is also the most widely used structural form in construction engineering. One of the main characteristics of reinforced concrete structures is that there are many factors that affect their quality. After quality problems occur, it is difficult to reinforce and repair them. [0003] During the construction of reinforced concrete structures, due to improper construction operations and other reasons, the strength of some concrete columns will not reach the design value or serious defects such as interlayers will be formed at the junction of concret...

AI Technical Summary

Problems solved by technology

Using the above-mentioned reinforcement methods such as enlarging the cross-section method and outsourcing steel method will affect the function of the structure and leave obvious reinforcement traces; although the reinforcement method of pasting carbon fiber does not affect the cross-sectional size of the column, it will also leave reinforcement traces

Especially when the above-mentioned construction defects appear in commercial housing, if the above-mentioned reinforcement methods are used to deal with them, residents are more likely to worry about the overall quality of the house due to the remaining reinforcement traces
