PRECAST CONCRETE (PC) COLUMN, BEAM-COLUMN CONNECTION STRUCTURE, AND METHOD FOR CONNECTING BEAM AND COLUMN

摘要

PROBLEM TO BE SOLVED: To provide a PC column which dispenses with scaffolding for a form in field connection work at a beam-column connection, and dispenses with a part where concrete is placed with a thickness greater than the structurally required thickness of cover concrete and which does not contribute to strength.;SOLUTION: The PC columns 20a and 20b are equipped with PC column bodies 22 and PC rising parts 25 which are integrally formed in a state of being protruded upward from outer peripheral sides of colum capitals 23; a column joint member 27 for connecting a main reinforcement 26 for the column is embedded in the colum capital 23; column-and-main-reinforcement connecting ends 26a and 26b, which are fixed to the column joint members 27 for the PC column 20b on a lower floor, are protruded downward from a column base 28; the joint members 27 for connecting ends 26a and 26b are embedded in positions which coincide with the ends 26a and 26b of the bodies 22 on an upper floor, on the upper end surface 25a of the rising part 25; and a field connection space 29 for the beam-column connection 21 is formed between the end surface 23a of the column capital 23 of the body 22 on the lower floor and the inside 25b of the rising part 25, and the end surface 28a of the base 28 of the body 22 on the upper floor.;COPYRIGHT: (C)2004,JPO
