A special-shaped combination structure and installation method of an assembled giant tube-in-tube circular steel pipe column

Abstract

The invention belongs to the technical field of structural engineering and particularly relates to a heterotype combination structure for fabricated giant tube-in-tube circular steel tube columns and a mounting method. The heterotype combination structure comprises at least two tube-in-tube circular steel tube columns, circular converting separation sleeves and high-strength steel connecting plates; the upper portions and the lower portions of the tube-in-tube circular steel tube columns are connected through the circular converting separation sleeves, and the left portions and the right portions of the tube-in-tube circular steel tube columns are connected through the high-strength steel connecting plates; and each tube-in-tube circular steel tube column comprises an external tube and an internal tube, and each circular converting separation sleeve comprises a base plate and vertical separation plates. According to the heterotype combination structure for the fabricated giant tube-in-tube circular steel tube columns and the mounting method, the influence of on-site construction on the quality is greatly lowered, connecting reliability of nodes is higher, and meanwhile, the problems that in the prior art, when the loading is large, the bearing capacity of a steel tube concrete structure cannot meet a stress requirement, and when the dimension of the columns is large, the building spaces at the nodes are wasted are solved; and construction is easy, mounting is convenient, reliability is good, and good market promotion prospects are achieved.

Description

technical field [0001] The invention relates to the technical field of structural engineering, in particular to an assembled giant tube-in-tube circular steel pipe column special-shaped combined structure and installation method designed based on high-strength steel and fiber concrete. Background technique [0002] With the development of technology, high-strength steel has gradually been applied to high-rise buildings and long-span building structures. The circular steel pipe concrete or steel concrete composite structure designed with high-strength steel, when the deformation is too large, the concrete combined with the high-strength steel pipe or steel will crack and break, and then the steel pipe or steel will buckle locally and cause structural damage. However, for circular concrete-filled steel tube columns designed with high-strength materials, the integrity of the inner and outer circular steel tubes and the inner-filled concrete is high, and due to the interaction b...

Problems solved by technology

At the same time, it solves the problem that when the load is large in the prior art, the bearing capacity of the steel tube concrete structure cannot meet the force requirements and when the size of the column is large, the construction space at the node is wasted.
