INTEGRAL CONSTRUCTION METHOD OF PILE AND COLUMN

PROBLEM TO BE SOLVED: To provide an integral construction method of a pile and a column capable of integrating a steel pipe-filled concrete column into a cast-in-place concrete pile with excellent workability. SOLUTION: This method integrates the steel pipe-filled concrete column 6 into the cast-in-place concrete pile 1 having a reinforcement 8 and a steel frame as a strength member on the inside; and includes a first process of arranging a steel pipe member 4 reaching the ground surface G from the underground by surrounding a pile head 3 before placing pile concrete 2 in advance when forming the cast-in-place concrete pile, a second process of pulling up the steel pipe member above the ground surface so that the lower part of the steel pipe member is left in the ground while surrounding the reinforcement of a pile head position by exposing the reinforcement of the pile head position of the cast-in-place concrete pipe after placing the pile concrete, and a third process of embedding the reinforcement of the pile head by placing column concrete 10 in the steel pipe member for setting an exposure part of the steel pipe member exposed above the the ground surface by being pulled up as the lower part of the steel pipe-filled concrete column.
