Abstract
The invention discloses a steel-concrete combined special-shaped column with thermal insulating and load bearing integrated. The special-shaped column comprises a cellular composite section, a thermal insulation material, longitudinal bars, stirrups and concrete. The cellular composite section is formed by welding a plurality of pieces of T-shaped steel with holes and circular steel tubes. The thermal insulation material is laid on the outer side of the cellular composite section. The longitudinal bars are erected on the circumferential outer side of the cellular composite section. The stirrups are annularly hooped on the outer sides of the longitudinal bars. The concrete is poured to coat the outer side of the cellular composite section, the outer side of the thermal insulation material, the outer sides of the longitudinal bars and the outer sides of the stirrups and is further filled in the circular steel tubes, and finally the steel-concrete combined special-shaped column is formed. The special-shaped column has the numerous advantages that the concrete is coated outside, so that the corrosion-prevention and fire-prevention effects of steel members are good, and cost is reduced; the spatial utilization rate of the inside of a room is high; thermal insulating and load bearing are integrated, and the construction speed is high; due to the fact that the concrete is coated outside, the cold bridge problem is solved; the assembly degree is high; the degree of standardization of the members is high; the concrete inside the tubes can be cast in situ at the construction site. The application and popularization prospect is good.
