The invention discloses an assembled composite concrete-filled steel tube column-steel beam connecting structure and an assembling method. The assembled composite concrete-filled steel tube column-steel beam connecting structure comprises a composite concrete-filled steel tube column and a steel beam, and further comprises a node ring, a connecting sheet and a plurality of connecting components, wherein reinforcing round steel tubes are embedded into the composite concrete-filled steel tube column; the node ring is provided with an upper flange, a lower flange and a web plate; a run-through connecting tube is arranged on the web plate; a plurality of reinforcing ribs are arranged on the periphery of the connecting tube; the upper flange and the lower flange are connected to the upper end and the lower end of the web plate respectively, and are provided with openings adapted to the end parts of the connecting tube; one end of the concrete-filled steel tube column is inserted into the opening, and a sleeve thereof is fixedly connected to the upper flange or the lower flange through the connecting components; the connecting sheet hoods the connecting tube and is fixed to the upper flange, the lower flange and the web plate in a sealing manner, and one or more small holes are formed therein; the steel beam is fixed to the upper flange, the lower flange and the web plate through theconnecting components. The assembled composite concrete-filled steel tube column-steel beam connecting structure guarantees the reliability of node connection, so that the construction of a node is simpler.
Description
technical field [0001] The invention relates to the field of civil engineering, in particular to an assembled composite steel pipe concrete column-steel beam connection structure and an assembly method. Background technique [0002] In recent years, my country has vigorously advocated the industrialization of construction and green buildings. Composite steel pipe concrete columns have the advantages of good bearing capacity, high fire resistance, good seismic performance, good plasticity and ductility, and are widely used in various fields of civil engineering. However, the processing and manufacture of the cast-in-place connection joints between composite steel pipe concrete columns and steel beams is complicated, the welding workload on the construction site is large, and the welding seam connection construction technology is high. Conducive to assembly construction. Contents of the invention [0003] The main purpose of the present invention is to overcome the above-me...
