Problems solved by technology

However, due to the influence of the original longitudinal steel bars and stirrups in the column, the chamfering radius of the column section is often small; and changing the shape of the section will affect the beauty or function of the building

Embodiment 1

[0022] Embodiment one: see figure 1 with figure 2 , the reinforcement method of the reinforced concrete rectangular column is as follows: in the reinforced concrete rectangular column 1 in this example, there are longitudinal steel bars 3 and stirrup bars 2 in the column; The outside of the concrete rectangular column 1 is wrapped with fiber-reinforced composite material cloth 4 to form lateral constraints on the reinforced concrete, thereby improving the seismic ductility of the reinforced concrete rectangular column 1 . The hardening operation steps are as follows:

[0023] (1) Grinding and cleaning the surface of the reinforcement area of ​​the reinforced concrete rectangular column 1;

[0024] (2) On the two opposite sides of the reinforcement area of ​​the reinforced concrete rectangular column 1, the small holes perpendicular to the sides are evenly distributed;

[0025] (3) Implanting the ribs 5 coated with bonding resin in the small holes;

[0026] (4) After the b...

Embodiment 2

[0029] Embodiment two: see Figure 4 , the present embodiment is basically the same as the above-mentioned implementation, the difference is that the outer end of the bar 5 is exposed from the surface of the reinforced concrete rectangular column 1 for an effective length, and the exposed section of the bar 5 is covered with a fiber-reinforced composite material cloth The strips or wires are wound and stretched to form the connector 6 to ensure the tension connection between the ribs 5 and between the ribs 5 and the fiber-reinforced composite cloth 4, thereby limiting the lateral expansion and deformation of the fiber-reinforced cloth and increasing the The confinement effect of the inner concrete.

Abstract

The invention relates to a reinforced concrete rectangular column reinforcing method, drilling small holes in the reinforcing region of the rectangular column, planting rib materials, winding FRP cloth onto the surface of the rectangular column and forming transverse restriction to the concrete column, where connecting drawknots are arranged to connect the rib materials with FRP cloth, so as to restrict lateral expansion deformation of the FRP cloth and improve the restriction to the in-column concrete, and the planted rib materials are wire materials with a certain compressive strength, and the FRP cloth is unidirectional, bidirectional or multiangular fiber reinforced composite cloth. And it is mainly applied to the reinforcing field of reinforced concrete structures and used to improve anti-seismic tensility of the reinforced concrete rectangular column.

Description

technical field [0001] The invention relates to a reinforcement method for a reinforced concrete rectangular column, which is to carry out construction on the original reinforced concrete column rectangular column to improve the ductility performance of the reinforced concrete column under earthquake load. Background technique [0002] Reinforced concrete structure is the most widely used structural form in engineering practice. Concrete columns are the main stress-bearing members in concrete structures, and their safety often determines the safety performance of the entire structure. Due to poor construction quality, increased design code level, exposure to harsh environments, structural overloading, natural disasters (earthquakes, hurricanes, etc.), it is easy to be damaged in moderate and large earthquakes, therefore, there are many reinforced concrete columns that need to be repaired. Reinforcement. Traditional reinforced concrete (RC) column reinforcement methods such...
