Fabricated square steel tube concrete joint capable of comprehensively improving seismic resistance and collapse resistance
The assembly type square steel tube concrete joint comprises a steel tube concrete column, steel beams located on the two sides of the steel tube concrete column and beam column connecting structures connected between the square steel tube concrete column and the steel beams, and the steel tube concrete column and the steel beams are perpendicularly arranged; the concrete-filled steel tube column comprises a square steel tube column, a group of perforated longitudinal ribs and a core concrete structure, the beam column connecting structure comprises an outer ring plate and a box body plate. The steel beam and the outer ring plate welded to the square steel pipe column in a sleeving mode are in bolted welding mixed connection, the box plate column is welded to the inner side of the beam-column joint and connected through the steel bars, the steel bars on the side of the box plate are fixed through the high-strength nuts, and a steel beam web body is designed to be a corrugated web. The problems of stress concentration and strain concentration of the concrete filled steel tubular column-steel beam joint can be effectively relieved, and the anti-seismic and anti-collapse performance is excellent.
本发明公开一种综合提升抗震和抗倒塌的装配式方钢管混凝土节点，包括钢管混凝土柱、位于钢管混凝土柱两侧的钢梁和连接于所述方形钢管混凝土柱与钢梁之间的梁柱连接构造，钢管混凝土柱与钢梁垂直布设；钢管混凝土柱包括方形钢管柱、一组开孔纵肋和核心混凝土结构；梁柱连接构造包括外环板和箱体板；钢梁与套焊在方形钢管柱上的外环板栓焊混合连接，梁柱节点内侧焊接箱体板柱并用钢筋连接，箱体板侧钢筋用高强螺母固定，钢梁腹板主体为波纹腹板设计，本发明设计合理、施工简便且力学性能好，能有效缓解钢管混凝土柱‑钢梁节点应力集中和应变集中问题，抗震和抗倒塌性能优良。
