Space constraint multi-cavity pipe-in-pipe steel bar concrete huge column and construction method
The invention relates to a space constraint multi-cavity pipe-in-pipe steel bar concrete huge column and a construction method. A huge column comprises a core steel pipe concrete part and a steel-encased pipe concrete part. A core steel pipe forms an inner cavity. The inner cavity is filled with inner cavity concrete, and a steel bar frame is arranged through the middle part of the inner cavity. The core steel pipe and the steel-encased pipe form an outer cavity. The outer cavity is filled with outer cavity concrete, and at least a steel bar frame is arranged through the outer cavity. The core steel pipe and the steel-encased pipe are connected through a vertical connection plate and form a space steel pipe structure. The outer steel pipe of the huge column is connected with the inner steel pipe through the vertical connection plate, the space steel pipe structure is formed, and the force bearing performance of traditional steel pipe concrete can be raised effectively. The huge column has a strong anti-pressure capability, steel and concrete combined action performances are good under action of long-term load. The huge column has good earthquake resistant behavior, fireproof performance and construction convenience.
