Assembly type PC column-column tenon type bolt connection joint
The invention provides an assembly type PC column-column tenon type bolt connection joint. The assembly type PC column-column tenon type bolt connection joint comprises an upper concrete column and a lower concrete column; an upper tenon and an upper mortise are arranged at the bottom of the upper concrete column in a crossed mode in the diagonal direction; a lower tenon and a lower mortise are arranged at the top of the lower concrete column in a crossed mode in the diagonal direction; the upper tenon and the lower mortise are connected in an adaptive and inserted mode, and the upper mortise and the lower tenon are connected in an adaptive and inserted mode; the upper tenon and the lower mortise are connected in an inserted mode, and the upper mortise and the lower tenon are connected in an inserted mode; a steel bar reserved on the upper tenon is aligned with a screw hole reserved in the lower mortise, a steel bar reserved on the lower tenon is aligned with a screw hole reserved in the upper mortise, and the steel bars are fixed in bolt mounting grooves through nuts correspondingly; and the vertical bearing capacity of the concrete columns is transmitted through connection of the upper tenon and the lower tenon, the area of the force transmission section is the same as that of the column section, bolt connection only bears the vertical load of the columns, part of axial force is borne in the normal state, tensile force is borne under the earthquake action, and stress is clear. The assembly type PC column-column tenon type bolt connection joint has the advantages of being simple in structure, convenient to construct, efficient in assembly and high in shear capacity.
一种装配式PC柱—柱榫式螺栓连接节点，包括上混凝土柱及下混凝土柱，所述上混凝土柱底部对角线方向交叉设置有上榫头及上卯口，下混凝土柱顶部对角线方向交叉设置有下榫头及下卯口，上榫头与下卯口、上卯口与下榫头分别相适配插接；将上榫头与下卯口、上卯口与下榫头相互插接，上榫头预留的钢筋与下卯口预留的螺孔对齐，下榫头预留的钢筋与上卯口预留的螺孔对齐，分别在螺栓安装槽内用螺帽进行固定；混凝土柱竖向承载力通过上、下榫卯连接进行传递，传力截面同柱截面的面积相同，螺栓连接仅承担柱的竖向荷载，正常状态下承担部分轴向力，地震作用下承担拉力，受力清晰；本发明具有结构简单、施工方便、装配高效、抗剪承载力强的优点。
