Reinforcement structure for frame beam column joint and construction method thereof
The invention discloses a reinforcement structure for a frame beam column joint and a construction method thereof. The reinforcement structure comprises an original frame column, a frame beam, a steel sleeve and a steel reinforcement cage, wherein the steel reinforcement cage comprises an insertion rib, an inner ring-beam ring rib and an outer ring-beam ring rib, and the frame beam is connected to the original frame column; the inner ring-beam ring rib and the outer ring-beam ring rib respectively penetrate through the frame beam to encircle the outer side of an original frame beam column joint; the outer ring-beam ring rib is positioned outside the inner ring-beam ring rib, and the insertion rib is vertically arranged and connected with the inner ring-beam ring rib; the steel sleeve is surrounded outside the original frame column. The reinforcement structure further comprises a reinforced concrete layer which is filled between the steel sleeve and the original frame column and used for burying the steel reinforcement cage. The reinforcement structure utilizes the restriction effect of the inner ring-beam ring rib and the outer ring-beam ring rib on the core area of the frame beam column joint, greatly improves the shear capacity and the stiffness of the frame beam column joint, and therefore improves the seismic performance of the frame beam column joint.
