Prefabricated column and column-column connecting joint
The prefabricated column comprises at least two column bodies and a connecting box arranged between the two column bodies, the upper end of the lower side column body extends out of a longitudinal bar and is inserted into the connecting box, and the prefabricated column further comprises a connecting hole formed in the upper end of the connecting box and correspondingly connected with a longitudinal bar extending out of the lower end of the upper side column body in an inserted mode; the toggle pin is fixedly connected to the inner wall of the connecting box; the upper end of the hole channel is communicated with the side wall of the column body, the lower end of the hole channel is communicated with the lower end of the column body, and the upper end of the connecting box is provided with a communicating opening corresponding to the lower end of the hole channel. The bottom longitudinal bars of the upper-layer column body are connected with the connecting holes in the connecting box in a penetrating and welding mode, the top longitudinal bars of the lower-layer column body are connected with the connecting box and the studs in the connecting box through grouting anchors, structural force transmission is clear, and the anti-seismic property and ductility are good; and at the connecting joints, the peripheral side walls of the connecting box have a strong restraining effect on the joint grouting material, and the mechanical property is good.
本发明公开了一种预制柱及柱柱连接节点，包括至少两个柱体以及设置在两个柱体之间的连接盒，下侧柱体上端伸出纵筋并插入连接盒内，还包括：连接孔，其开设在连接盒上端，与上侧柱体下端伸出的纵筋对应插接；栓钉，其固定连接在连接盒内壁；孔道，其设置在柱体内，上端连通柱体侧壁，下端连通柱体下端设置，所述连接盒上端设置有与孔道下端对应的连通口。本发明通过上层柱体底部纵筋与连接盒上的连接孔穿焊连接，下层柱体的顶部纵筋与连接盒以及内部的栓钉通过灌浆浆锚连接，结构传力明确，抗震性能及延性好；且连接节点处，连接盒四周侧壁对节点灌浆料约束作用强，力学性能好。
