Full-bolted connection joint and method for box-shaped beam column with plastic hinge
The invention discloses a full-bolted connection joint and method for a box-shaped beam column with a plastic hinge, and relates to the technical field of fabricated buildings. The full-bolted connection joint comprises a box-shaped column, a cantilever box girder, a box-shaped beam and a connecting assembly; the cantilever box girder is connected with the box-shaped column; and the cantilever box girder is connected with the box-shaped beam through the connecting assembly. Connecting plates with nuts are adopted on the inner sides of a welded box-shaped beam, the number of parts can be reduced, loss is reduced, and installation is convenient; and a rolled box-shaped beam adopts a connecting box girder, the connecting rigidity is large, the number of assemblies is small, and the performance is excellent. Bolt connection is adopted, box-shaped beam column joints are free of field welding seams, welding residual stress or residual deformation, and the quality is easy to guarantee. The field labor intensity is low and the efficiency is high; and the requirements of fabricated buildings and green construction technologies are met. Bolts are adopted as mature products, an applicable theoretical basis is complete, and the manufacturing cost is low. Existence of a plastic hinge of the cantilever box girder can be controlled through the closing mode of mounting holes of the cantilever box girder, and the connection joint is suitable for multi-story and high-rise buildings in areas with or without seismic fortification requirements.
本发明公开一种带塑性铰箱形梁柱全螺栓连接节点及方法，涉及装配式建筑技术领域，包括箱形柱、悬臂箱梁、箱形梁和连接组件；悬臂箱梁与箱形柱连接，悬臂箱梁通过连接组件与箱形梁连接。焊接箱形梁内侧采用带螺母的连接板，可减少零部件数量、降低损耗、方便安装；轧制箱形梁采用连接箱梁，连接刚度大、组件数量少、性能优良。采用螺栓连接，箱形梁柱节点无现场焊缝，无焊接残余应力及残余变形，质量易保障；现场劳动强度低、效率高；符合装配式建筑、绿色施工技术的要求。采用螺栓为成熟产品、适用的理论依据完备且造价低。通过悬臂箱梁安装孔的封闭方式，可控制悬臂箱梁塑性铰的发生与否，适宜有或无抗震设防要求地区的多高层建筑。
