COLUMN CONNECTING STRUCTURE

PROBLEM TO BE SOLVED: To reduce manhaurs for connecting a steel-pipe column in a column connecting structure and costs. SOLUTION: A column connecting structure is formed by connecting a steel- pipe column having steel pipes 5, 6 arranged in the vertical direction with a concrete structure installed at the lower and of the steel-pipe column. Reinforcement 16 is placed across spaces in the concrete structure 12 and the steel pipe 5. Concrete 7 is placed between the reinforcement 16 and the steel pipe 5 and in contact with the concrete structure 12, and a lap joint is constructed of the steel pipe 5, the reinforcement 16, and the concrete 7.
