  • Connection structure, concrete-encased concrete-filled steel tube column and construction method
    Patent number: 11142911
    Abstract: The present invention discloses a concrete-encased concrete-filled steel tube (CFST) column connection structure, a concrete-encased CFST column comprising such a connection structure, and a construction method for constructing such a concrete-encased CFST column, in the technical field of connection of concrete-encased CFST columns. Exposed steel tubes at the connection ends of two split concrete-encased CFST columns are connected through a core positioning sleeve of a concrete-encased CFST column connection structure. Exposed longitudinal bars of the two split concrete-encased CFST columns are connected through longitudinal bar sleeves of the concrete-encased CFST column connection structure. A space between the two split concrete-encased CFST columns is sealed by an external sealing sleeve of the concrete-encased CFST column connection structure; and the space in the external sealing sleeve and around the first and second exposed steel tubes is filled with a concrete slurry.
