Column connection joint based on civil engineering

The invention relates to the technical field of civil engineering, in particular to a column connection joint based on the civil engineering. The column connection joint includes a vertical column anda horizontal beam. The vertical column is connected with the horizontal beam through a first connecting part in a detachable mode. The vertical column includes an upper column, a middle column and alower column. The upper column is connected with the middle column through a second connecting part in a detachable mode. The lower column is connected with the middle column through a third connecting part in a detachable mode. The column connection joint based on the civil engineering is simple in structure, safe and reliable, and is convenient to assemble and disassemble; defects that welding is prone to generating fire disasters and the consumed time is long can be avoided; and the construction progress is greatly improved. 本发明涉及土木工程技术领域，具体涉及了种基于土木工程的柱连接节点，包括立柱和横梁，所述立柱与所述横梁通过第连接部可拆卸连接；所述立柱包括上柱、中柱和下柱，所述上柱与所述中柱通过第二连接
