Reinforced structure and reinforced method for large-tonnage concrete column replacement

Abstract

The invention discloses a reinforced structure for large-tonnage concrete column replacement. The reinforced structure comprises a plurality of inner bundle steel plates which surround the outer circumference surface of a concrete column. The adjacent edges of the inner bundle steel plates are fixedly connected to form an integrated structure, the edges of the inner bundle steel plates are fixedlyconnected with reinforced angle steel, and the end portions of the inner bundle steel plates are fixedly connected with joint angle steel. A plurality of preformed holes are formed in the surfaces ofthe inner bundle steel plates and connected with the concrete column in a pre-fastening mode through a fastening structure. The outer circumference surfaces of the inner bundle steel plates are tightened by structural steel hoops, and adhesives are poured between the inner surfaces of the inner bundle steel plates and the outer circumference surface of the concrete column to bond the inner surfaces of the inner bundle steel plates and the outer surface of the concrete column. The invention also discloses a reinforced method using the reinforced structure for the large-tonnage concrete columnreplacement. Compared with the prior art, the technical scheme has the advantages of convenient construction and reliable structure and the like, and can simplify the steps of defect replacement of the concrete column, ensure the structural strength of the concrete columns after the defect replacement and avoid the impact on subsequent use.

Description

technical field [0001] The invention relates to the technical field of concrete member reinforcement, in particular to a large-tonnage concrete column replacement reinforcement structure and reinforcement method. Background technique [0002] During the construction acceptance and later use of the project, it is often encountered that the quality of the concrete column does not meet the standard or the concrete column does not reach the design strength and needs to be reinforced. Concrete replacement method, in which the enlarged cross-section reinforcement method increases the force section of the concrete column by increasing the cross-section; the outsourcing steel reinforcement method increases the stiffness and compressive strength of the concrete column by outsourcing the steel; the traditional concrete replacement method increases the underpinning of the reinforced concrete column Caps replace defective concrete. [0003] However, there are certain defects in the abo...

AI Technical Summary

Problems solved by technology

[0003] However, there are certain defects in the above methods. For example, the method of increasing the cross section makes the axial force on the upper part of the reinforced concrete column larger, and the section of the reinforced concrete column increases more than the original section, which is not conducive to decoration and visual senses. and space utilization

However, the external steel reinforcement method does not fundamentally solve the defects of the concrete column, but only relies on the steel to bear the force, and the maintenance and protection requirements for later use are relatively high.

However, the traditional concrete replacement method needs to add a large-scale reinforced concrete conversion platform, so the construction has a greater impact and the construction surface is larger
