Embodiment Construction
[0014] The reinforcement method of reinforced concrete beam-column joint of the present invention, as Figure 1-3 As shown, the specific implementation steps are as follows:
[0015] (1) Positioning
[0016] First remove the stucco layer in the reinforced concrete beam-column joint area, and determine the drilling position and column corner chamfering position at the junction of beam 1 and column 2. All drilling positions and chamfering positions should be at the same elevation.
[0017] (2) Drilling and chamfering
[0018] Drill holes in the beam 1 against the four ends of the column 2 so that the holes pass through the cross-section of the beam 1 against the cylindrical face of the column 2. For the hole 11 on the side where the prestress is applied, the aperture should ensure that two steel hinge lines 3 can pass through the cylinder surface of the column 2, and the aperture diameters of the holes 12 on the other three sides should ensure that one steel hinge line 3 can p...
