Problems solved by technology

[0003] Although concrete-filled steel tube composite columns have many advantages, in the face of complex construction requirements in practical applications, sometimes it is necessary to set the connecting nodes in the composite steel tube concrete columns. The columns are connected together, and the connection strength is guaranteed, but there is no connection structure that can be connected in the steel tube concrete composite column

Abstract

A concrete-filled steel pipe column connecting structure, a concrete-filled steel pipe column, and a construction method, the concrete-filled steel pipe column connecting structure (1) comprising a core positioning sleeve (101) used for connecting two exposed steel pipes at opposite positions, a plurality of longitudinal rib sleeves (104) used for connecting two exposed longitudinal ribs at opposite positions, a hoop restraint sleeve (105) used for restraining the core positioning sleeve (101) and the longitudinal rib sleeves (104), and an external sealing sleeve (107) used for sealing the space between a first split concrete-filled steel pipe column (2) and a second split concrete-filled steel pipe column (3); the concrete-filled steel pipe column comprises the first split concrete-filled steel pipe column (2), the second split concrete-filled steel pipe column (3), and the concrete-filled steel pipe column connecting structure (1); and the construction method for the concrete-filled steel pipe column comprises the following steps: assembling the concrete-filled steel pipe column connecting structure (1), respectively connecting the concrete-filled steel pipe column connecting structure (1) to the first split concrete-filled steel pipe column (2) and the second split concrete-filled steel pipe column (3), and grouting. The present concrete-filled steel pipe column connecting structure (1) connects the first split concrete-filled steel pipe column (2) and the second split concrete-filled steel pipe column (3), and enables the connecting nodes to be arranged in the concrete-filled steel pipe columns whilst ensuring the strength of the connection.

Description

technical field [0001] The invention relates to the technical field of steel pipe concrete composite column connection, in particular to a steel pipe concrete composite column connection structure capable of setting connection nodes in the steel pipe concrete composite column and a construction method thereof. Background technique [0002] The concrete-filled steel tube composite column fully combines the characteristics of steel tube and concrete. Its high section bearing capacity can effectively reduce the section size of the column. The existence of the steel tube also makes it have good ductility, and because the steel tube is surrounded by concrete and isolated from the outside world , so that it has good fire resistance and corrosion resistance. In addition, the concrete-filled steel tube composite column also has the advantages of good seismic performance, convenient construction, and low cost. Due to the many advantages of CFST composite columns, it has been widely ...
