A method for quickly strengthening reinforced concrete corner columns

Abstract

The invention discloses a method for accelerating reinforcement of a reinforced corner column. The method comprises the following steps: fabricating anchor angle steel and reinforcing angle steel which are matched with the size of the section of the corner column, and reserving bolt holes in two limbs of the anchoring angle steel; grinding, cleaning and flattening a bonding anchoring region of the corner column; mounting the anchoring angle steel at designed positions, drilling bolt holes in the bonding anchoring region according to the positions of the reserved holes on the anchoring angle steel, and cleaning and chambering the holes; coating the bonding anchoring region of the corner column with building structure adhesives, closely placing the two limbs of the anchoring angle steel on the bonding anchoring region, mounting the reinforcing angle steel at the designed positions, welding the two limbs of the anchoring angle steel and the reinforcing angle steel together to form a steel cage; gluing the bolts holes in the anchoring angle steel and the corner column, and implanting self-locking anchor rods; tightening screw caps of the self-locking anchor rods to fix the anchoring angle steel and the reinforcing angle steel on the corner column. The method has the advantages that the a small number of reinforcing assemblies are used, the construction steps are simple, and the construction period is short; the bearing capacity, the lateral stiffness and the seismic ductility of the column can be greatly improved; the corner column is high in whole performance and high in reliability.

Description

technical field [0001] The invention relates to a reinforcement method, in particular to a method for rapidly reinforcing reinforced concrete corner columns. Background technique [0002] A large number of reinforced concrete columns in industrial and civil buildings have problems such as insufficient bearing capacity and other problems affecting safety and use functions due to design and construction defects or aging, damage and disasters in the long-term use process. Reinforcement is urgently needed . For example, in civil buildings, due to the reconstruction of building structures, the addition of machines in industrial plants and the overloading of bridge structures, the bearing capacity of the original structure is insufficient, and it is urgent to greatly increase the bearing capacity of reinforced concrete columns through reinforcement methods. [0003] At present, in the actual reinforcement of reinforced concrete corner columns, the most widely used reinforcement m...

Problems solved by technology

[0005] The purpose of the present invention is to provide a fast reinforcement method that can significantly improve the bearing capacity and ductility of the reinforced corner column in view of the defects existing in the existing reinforcement method, and solve the problem of increasing the cross-section of the original structure due to the reinforcement of the enlarged cross-section existing in the prior art. It is relatively large, which has a great impact on the self-weight of the structure, and the site needs formwork, and the maintenance period is long, so it cannot be put into use quickly; it also solves the problem of limited ductility improvement of the columns reinforced by outsourcing angle steel, and the problem of many construction components; at the same time, it solves the problem of The problem of limited increase in the bearing capacity of viscose fiber reinforced composite materials after reinforcement; and avoid the problem of high technical requirements for external prestressed reinforcement method and the difficulty of anchoring treatment
