JOINT STRUCTURE OF COLUMN AND PRECAST BEAM AND JOINT METHOD OF COLUMN AND PRECAST BEAM
To provide a joint structure of a column and a precast beam in which the most part is precast, and which has excellent workability, and can easily be repaired even if it is damaged.SOLUTION: A joint structure of a column and a precast beam is formed by reinforced concrete, and includes: a precast beam part 31 which becomes a body of a beam; a joint reinforcement 22 embedded in an upper end part 21 of the column 2, and extended toward the precast beam part; and a high intensity connection part 4 formed by high intensity concrete between a side surface of the upper end part of the column and an end surface of the precast beam part. Then, the joint reinforcement is formed by a reinforcement which has a large diameter or high intensity, and an end part is arranged at the high intensity connection part, and an end part 321 of a beam main reinforcement 32 is also arranged at the high intensity connection part, and it is set in such a manner that when it receives an external force, an end part of the precast beam part is damaged prior to the high intensity connection part.SELECTED DRAWING: Figure 1
【課題】大部分がプレキャスト化されて施工性に優れているうえに、損傷したとしても修復などが容易に行える柱とプレキャスト梁の接合構造を提供する。【解決手段】鉄筋コンクリートによって形成される柱とプレキャスト梁の接合構造である。梁の本体となるプレキャスト梁部３１と、柱２の上端部２１に埋設されてプレキャスト梁部に向けて延伸される接合鉄筋２２と、柱の上端部の側面とプレキャスト梁部の端面との間に高強度コンクリートによって形成される高強度接続部４とを備えている。そして、接合鉄筋は、太径又は高強度の鉄筋によって形成されて端部が高強度接続部に配置されるとともに、梁主筋３２の端部３２１も高強度接続部に配置され、外力を受けた際に、高強度接続部よりもプレキャスト梁部の端部の方が先に損傷するように設定されている。【選択図】図１
