ANCHORAGE STRUCTURE OF BEAM MAIN REINFORCEMENT

摘要

PROBLEM TO BE SOLVED: To rationalize the anchorage of a beam main reinforcement end part to a joint part more than that by a hook. SOLUTION: An anchorage head part 12 is provided at the end parts of a beam main reinforcement 11 integrally, and the anchorage head parts 12 are fixed to a joint part 4 to a column 3. The anchorage head part 12 is formed by fixedly fitting a anchorage plate to the end parts of the beam main reinforcement 11. The anchorage head part 12 provided at both end parts of the beam main reinforcement 11 is fixed to the joint part 4 to the outer peripheral column 3a, and a node 15 provided at the middle part of the beam main reinforcement 11 integrally is fixed to the joint part 4 to the intermediate column 3b. A high strength deformed reinforcing bar is used as the beam main reinforcement 11. A steel fiber-reinforced concrete is used as a concrete to be placed into the joint part 4.
