Manufacturing Method for Hollow Precast Concret encased Steel Column and Dry splicing Methods for the Same
The outer pole 100 according to the present invention, is produced by the precast system having a hollow 200 inside the well and forming the outer surface of the cylinder; Inner post 300 is formed by cast in place concrete into said hollow (200) And the outer pole 100 and inner pole 300, the reinforcing member 400 is formed between; the precast recessed synthesis, comprising a step of including a pole is provided. In accordance with the invention in the construction of the composite column so that it does not require an on site construction details such as the steel reinforcement and the reinforcement, installation of the mold to achieve a shortening, and it is possible to improve the workability.
