Energy-dissipation self-resetting beam and column joint connection device of steel structure
The invention relates to an energy-dissipation self-resetting beam and column joint connection device of a steel structure. The device comprises a steel frame column, a short cantilever beam just connected to one side of the steel frame column and a connecting beam spliced at the other end of the short cantilever beam, wherein the flange and web splices of the connecting beam and the short cantilever beam are connected through energy dissipation connection components, and a U-shaped steel damper is arranged on the inner side of the flange splice of the connecting beam and the short cantileverbeam; a group of anchor plates is respectively arranged at the symmetrical positions of the two sides of a web of the connecting beam; and the steel frame column is connected with the upper side and the lower side of each anchor plate through prestressed steel bars arranged in a horizontal direction. The U-shaped steel damper dissipates energy at the splices of the short cantilever beam and the connecting beam to ensure that the beam and column bodies keep the elasticity from being broken. Moreover, the structure is simple, most of the structure is bolted, the modularity degree is high, disassembly, replacement and repair are easy, the construction is convenient, and the device conforms to the development trend of the construction industry. Meanwhile, the prestressed steel bars can provideself-restoring force and have an ideal self-resetting effect.
一种耗能自复位钢结构梁柱节点连接装置，所述装置包括钢框架柱和刚接在钢框架柱一侧形成的悬臂短梁，以及拼接在悬臂短梁另一端的连接梁，所述连接梁和悬臂短梁的翼缘及腹板拼接处均通过耗能连接组件连接，且所述连接梁和悬臂短梁翼缘拼接处内侧还设置有U型钢阻尼器；所述连接梁腹板的两侧对称位置分别设置有一组锚固板，且所述钢框架柱和锚固板的上下两侧之间均通过沿水平方向设置的预应力钢筋连接。本发明U型钢阻尼器在悬臂短梁和连接梁拼接处耗能，确保梁柱主体保持弹性不被破坏；且构造简单，大部分采用螺栓连接，模块化程度高，易于拆卸替换修复，施工便捷，符合建筑行业的发展趋势；同时预应力钢筋可提供自恢复力，具有理想的自复位效果。
