JOINT STRUCTURE BETWEEN PILLAR AND BEAM IN UPPERMOST FLOOR
PROBLEM TO BE SOLVED: To provide a joint structure between a pillar and a beam in an uppermost floor capable of improving the workability as well as preventing increase of amount of reinforcement bar while ensuring a predetermined strength.SOLUTION: A pillar head part T in an uppermost floor of a reinforced concrete structure where a pillar A and a beam B are joined with each other, includes an enlarged diameter portion 1a formed in the upper end part of a pillar main reinforcement 1 of the pillar A, and an enlarged diameter portion 2a formed in the end part of a beam main reinforcement 2 of the beam B. A beam upper end reinforcement 2A of the beam main reinforcements 2 is bent downward and the end part of the bent-part is positioned in the pillar head part T. The pillar head part T also includes: a U-shaped hairpin-shaped reinforcing bar 5 which is disposed on the beam upper end reinforcement 2A with the opening oriented downward; and a pillar confining steel 6 connecting a pair of pillar main reinforcements 1, 1 to each other.SELECTED DRAWING: Figure 1
【課題】所定強度を確保しつつ配筋量の増加を抑えることができるとともに、施工性を向上させることができる最上階における柱と梁との接合構造を提供する。【解決手段】鉄筋コンクリート構造物の最上階で柱Ａと梁Ｂとが接合される柱頭部Ｔにおいて、柱Ａの柱主筋１の上端部および梁Ｂの梁主筋２の端部にはそれぞれ拡径部１ａ、２ａが形成され、梁主筋２のうち梁上端筋２Ａが下方に向けて折り曲げられ、その折曲げ部分の端部が柱頭部Ｔ内に配筋されてなり、柱頭部Ｔには、梁上端筋２Ａの上方から開口側を下方に向けて配筋されたコ字状のかんざし筋５と、対向する柱主筋１、１同士を連結する柱拘束筋６と、を備えている。【選択図】図１
