Abstract

The invention belongs to the technical field of building structures, and particularly relates to an inflection point prefabricated column connecting node and an assembling method thereof. The prefabricated column connecting node comprises an upper prefabricated column and a lower prefabricated column which are arranged up and down, protruding heads are arranged at the splicing ends of the upper prefabricated column and the lower prefabricated column, the protruding heads of the upper prefabricated column and the lower prefabricated column are respectively sleeved with a first ferrule and a second ferrule, the first ferrule and the second ferrule are respectively anchored in the upper prefabricated column and the lower prefabricated column, the first ferrule and the second ferrule are connected through connecting plates, the upper prefabricated column and the lower prefabricated column are combined to form a ring groove, and the connecting plates are arranged in the ring groove. According to the prefabricated column connecting node, the force is more simple compared with the force in a node core region, the heights of the prefabricated columns are set between the inflection point ofthe upper column and the inflection point of the lower column, the shear force is equal to the shear force in the node core region, the bending moment is zero, the torque is almost negligible, and the overall safety of a structure and the lateral stiffness of the overall structure are increased.

Description

technical field [0001] The invention belongs to the technical field of building structures, and in particular relates to a connection node of a prefabricated column with an inflection point and an assembly method thereof. Background technique [0002] During the construction and assembly of prefabricated buildings, the connection methods of prefabricated columns mainly include the following two methods: (1) Grouting sleeve connection method: Insert the ribbed steel bar to be connected into the metal sleeve for "butting", and inject high-strength early Strong and micro-expansion grouting material, the grouting material forms a large positive stress between the sleeve wall and the steel bar, and generates a huge friction force on the rough surface of the ribbed steel bar, thereby transmitting the axial force. This connection method has high requirements for workers. Every longitudinal bar of the column needs to be connected with a sleeve. Therefore, the alignment of the steel ...
