The invention discloses a prefabricated self-resetting energy-consuming beam-column joint based on a duplex concrete-filled steel tubular column in the technical field of prefabricated concrete buildings, comprising a duplex column and a prefabricated beam. The node connecting parts are fixed and installed by the node bolts. The left and right ends of the prefabricated beam are respectively embedded with beam end connecting parts and anchor plates. The left side of the beam end connecting parts is fixed with friction plates parallel to the vertical surface. The friction plates pass through In the middle of the node connection part and welded to the beam end connection part, a number of prestressed steel strands are passed through the prefabricated beam, the right end of the prestressed steel strand is fixedly connected with the anchor plate, and the left end is fixed on the right side of the node connection part through the anchor head. On the side plate, the present invention has good seismic reset reliability, more convenient installation and disassembly, and low use cost, and is suitable for popularization and application.
Description
technical field [0001] The invention relates to the technical field of prefabricated concrete buildings, in particular to a prefabricated self-reset energy-consuming beam-column joint based on a composite steel tube concrete column. Background technique [0002] Existing published or publicly used technologies: the existing prefabricated self-resetting energy-consuming nodes mostly use prestressed steel strands 13 and SMA materials to provide reset force, and most of the reset devices are installed on the construction site. On November 26, 2019, the State Intellectual Property Office authorized and announced the invention patent announcement number of "an assembled self-resetting node": CN109868898B, the invention relates to an assembled self-resetting node, including support columns, beams, pre- Stress steel bar, universal wheel, corbel, rubber gasket and angle steel; the middle end of the support column is provided with corbel, the top of the corbel is provided with two st...
