STRUCTURE AND METHOD OF JOINING CONCRETE-FILLED STEEL PIPE MEMBER AND REINFORCED CONCRETE MEMBER

PROBLEM TO BE SOLVED: To provide a structure and a method capable of joining a concrete-filled steel pipe member and a reinforced concrete member through a short insertion length. SOLUTION: At the joining part between a concrete-filled steel pipe column 1 and a reinforced concrete beam 2, the insertion part 3b having one end is disposed in the concrete 12 of the concrete-filled steel pipe column 1, the insertion part 3a having the other end is disposed in the concrete 22 of the reinforced concrete beam 2, and insertion reinforcements 3 are so installed inside the steel pipe 11 as to be arranged along the circle. Surrounding reinforcements 4 are so spirally wrapped around the insertion reinforcements 3 as to surround the outer side of the insertion reinforcements 3. The concretes 12, 22 at the joining part are deposited and hardened to form a concrete-filled steel pipe column/reinforced concrete beam joint structure. COPYRIGHT: (C)2008,JPO&INPIT
