The invention discloses an assembly type circular steel pipe column joint connecting device and an assembly method. The assembly type circular steel pipe column joint connecting device comprises a steel pipe column, connecting pieces and steel beams, a plurality of steel beams are arranged on the outer side of the steel pipe column in an annular array mode, the steel beams and the steel pipe column are connected through the connecting pieces, and a plurality of outer ribs are arranged on the lower portion of the steel pipe column in the annular array mode; the connecting pieces are correspondingly installed at the tops of the outer ribs, each connecting piece comprises a steel body, a plurality of clamping grooves are formed in each steel body in the annular array mode, and steel plates are connected into the clamping grooves and connected with the steel beams. According to the assembly type circular steel pipe column joint connecting device and the assembly method, the problem that welding between an existing circular steel pipe column and a profile steel beam is poor can be solved, and the space occupancy rate is small; the rigidity and the bearing capacity of a joint are improved to a great extent by overlapping and sleeving the connecting pieces such as annular thin steel plates, and meanwhile, the joint also has better integrity and stability; the assembly type circular steel pipe column joint connecting device has more mobility in a bolt penetrating hole fixing mode, connection between materials is reinforced, and the assembly type circular steel pipe column joint connecting device further has the advantages of being convenient to mount and dismount, large in application range and the like.

本发明公开了一种装配式圆形钢管柱节点连接装置及装配方法，包括钢管柱、连接件和钢梁，所述钢管柱的外侧环形阵列有多根钢梁，钢梁与钢管柱之间均通过连接件连接，钢管柱的下部环形阵列有多个外肋，所述的连接件对应安装在外肋顶部，所述的连接件包括钢体，钢体上环形阵列有多个卡槽，卡槽内连接有钢板，所述的钢板与钢梁连接。本发明可以解决现有的圆形钢管柱与型钢梁之间焊接较差的问题，且空间占用率小；通过叠加套入环形薄钢板等连接件，使节点的刚度和承载力得到很大程度上的提高，同时也具有更好的整体性和稳定性；利用螺栓穿孔固定的方式，使装置具有更多的可活动性，不仅加固了材料之间的连接，还具备了便于安装拆卸、适用范围大等优势。
