Recycled concrete beam-column joint for welding flange stiffening reinforcements by using cross-shaped steel plate and construction method
The invention discloses a recycled concrete beam-column joint for welding flange stiffening reinforcements by using a cross-shaped steel plate. The recycled concrete beam-column joint comprises a pole longitudinal rib, a pole stirrup and a stiffener; the pole stirrup is fixedly bound or welded with the pole longitudinal rib; the stiffener is arranged at the position of the beam-column joint, is welded or fixedly bound with the pole stirrup and a beam, and comprises the cross-shaped steel plate and a flange plate welded to the periphery of the cross-shaped steel plate; and the flange plate is perpendicular to the cross-shaped steel plate. The recycled concrete beam-column joint has good rigidity and ductility under the effect of low cyclic loading, crack resistance and shear strength of the beam-column joint are improved, energy dissipation capacity of the structure is improved, brittle failure of the joint is prevented, and the anti-seismic property of the joint is improved obviously.
