JUNCTION STRUCTURE BETWEEN REINFORCED CONCRETE COLUMN AND BEAM, AND CONSTRUCTION METHOD FOR THE SAME

PROBLEM TO BE SOLVED: To provide a junction structure between a reinforced concrete column and a beam and a construction method for the same that enhance strength at a junction between a reinforced concrete column and a beam and mitigate a labor for reinforcing bar arrangement work at the junction.SOLUTION: In an area on a part of a main reinforcing bar 2a of a column 2 in a longitudinal direction, a metallic cylindrical body 5 is installed with the main reinforcing bar 2a inserted therethrough. Through an opening 7 formed on a side surface of the cylindrical body 5, a main reinforcing bar 3a of a beam 3 is extended to reach the main reinforcing bar 2a of the column 2. The main reinforcing bar 2a of the column 2 and the main reinforcing bar 3a of the beam 3 are surrounded by a concrete mold 12, and concrete 4 is cast in the concrete mold 12 to form the column 2 and beam 3. Then, the concrete 4 of the column 2 and the beam 3 is integrated through the opening 7, and the beam 3 is joined on an outer peripheral surface of the cylindrical body 5.SELECTED DRAWING: Figure 1 【課題】鉄筋コンクリート製の柱と梁の接合部の強度を向上させるとともに、接合部における鉄筋工事の軽労化を図ることができる鉄筋コンクリート製の柱と梁との接合構造およびその構築方法を提供する。【解決手段】柱２の主鉄筋２ａの長手方向一部の範囲に、主鉄筋２ａを挿通させて金属製の筒状体５を配置する。筒状体５の側面に形成された開口部７を通じて梁３の主鉄筋３ａを柱２の主鉄筋２ａまで延在させた状態にする。そして、柱２の主鉄筋２ａおよび梁３の主鉄筋３ａを型枠１２で囲んで、この型枠１２内にコンクリート４を打設することにより柱２および梁３を形成し、柱２と梁３のコンクリート４を開口部７を通じて一体化させて梁３を筒状体５の外周面に接合させる。【選択図】図１
