Self-resetting beam-column joint device for building structure
The invention relates to a self-resetting beam-column joint device for a building structure. The self-resetting beam-column joint device comprises an H-shaped steel column and an H-shaped steel beam, a shear plate is fixedly connected to flange plates of the H-shaped steel column, a long hole matched with a long hole of the shear plate and used for being connected to the H-shaped steel column is formed in a web of the H-shaped steel beam, a corner cut from the edge of the upper flange plate as the corner top end to the lower flange plate is arranged on the web of the H-shaped steel beam, an anchoring plate is arranged between the flange plates of the H-shaped steel beam, and a resetting device is arranged between the flange plate at the joint of the H-shaped steel column and the anchoring plate of the H-shaped steel beam. According to the self-resetting beam-column joint device, due to the fact that a mode that a lower flange of the H-shaped steel beam is chamfered is adopted, additional damage to a floor slab and a frame column is eliminated; the shear plate is arranged to provide a stable transmission path for shear force to meet the requirement of open and close movement of the joint; the pre-tightening force of the resetting device and the arrangement of a disc spring can be adjusted, and the initial rigidity, strength and deformability of the joint are flexible and changeable; the disc spring is made of a SMA material, so that the deformation capacity of the joint is greatly enhanced, and meanwhile residual deformation can be controlled at a low level; and the structure is simple, and assembly and construction are easy.
本发明涉及一种建筑结构用自复位梁柱节点装置，它包括H型钢柱和钢梁，H型钢柱翼缘板上固连剪切板，H型钢梁腹板上有与剪切板长孔相匹配的连接H型钢柱用长孔；H型钢梁腹板上有一个自上翼缘板边缘为角顶端，到下翼缘板的切角；H型钢梁翼缘板间有锚固板，H型钢柱节点处的翼缘板与H型钢梁锚固板间有复位装置。因采用本发明H型钢梁下翼缘“削角”方式，消除了对楼板和框架柱的附加损伤。设置剪切板提供了剪力的稳定传递路径满足节点“开合运动”的需求。复位装置的预紧力和碟簧布置可调整，节点的初始刚度、强度和变形能力灵活多变；碟簧为SMA材料，大大增强了节点的变形能力，同时残余变形可控制在较低水平。本发明的结构简单，易于组装施工。
