Locally Strengthened Prefabricated Concrete Frame Beam-column Connection Joint
Abstract A locally strengthened prefabricated concrete frame beam-column connection joint includes a precast concrete column (1) and a precast concrete beam (2), wherein one end of the concrete 00 beam (2) is placed on a concrete protection layer at the upper end of the concrete column (1) to form a joint core area (3), and a U-shaped key groove (21) is retained at the end of the concrete beam (2), a core beam (22) and a PC steel bar (23) are arranged in the U-shaped key groove (21), the free end of the PC steel bar (23) protruding from the end portion of the concrete beam (2), and the PC steel bar is subjected to an unbonded treatment by using a PVC pipe (4) in the key groove; and head tamping short rebars (5) are arranged at the upper portion and the lower portion in the joint core area (3) of the concrete beam (2) respectively, and a long common steel bar (6) is arranged at the upper portion of the concrete beam (2). The beam-column connection joint has the advantages of low cost, strong shear resistance of the beam-column joint surface, convenient construction, good seismic performance, high resistance to deformation and good crack performance.
