Setting steel rebars in steel tube columns can improve the synergistic performance of steel tube and concrete, the design codes of some countries in North Africa require that the concrete in the concrete-filled steel tube column is reinforced according to the concrete reinforcement ratio. In view of the challenge of installing rebars in inclined steel tube column, the idea of prefabricated rebar cage, rebar cage fixed with steel tube and integral hoisting is determined. Starting from design, the distance between the steel cage and shear stud is defined, and the non-contact splice connection between the rebar cage is proposed. In the process of installation, exploring the use of rebar chute to overcome the adverse effect of shear studs inside the steel tube, separable welding double cross positioning bars is adopted to fix the rebar cage, and integral hoisting method is applied to install the rebars inside the steel tube column. Finally, concrete jacking technology is used to cast the concrete in the steel tube column. The practicability and effectiveness of the technology is verified through practice, and comprehensive benefits are obtained.
