JOINT STRUCTURE BETWEEN COLUMN AND BEAM, AND METHOD FOR CONSTRUCTING JOINT STRUCTURE BETWEEN COLUMN AND BEAM

To provide a joint structure between a column and a beam, and a method for constructing the joint structure between the column and the beam, capable of ensuring desired restraint effect of filled concrete, shear transmission performance and axial force transmission performance of the column, and improving workability.SOLUTION: There is provided a joint structure 1 between a column 2 using a concrete pipe and a beam 3 of a steel structure. The column 2 includes: a fiber-reinforced concrete pipe 21 formed of fiber-reinforced concrete 210 in which a plurality of fibers are mixed in an uncured concrete-based material; a plurality of connecting reinforcing bars 23 arranged inside the fiber-reinforced concrete pipe 21 and extending in a vertical direction; a closing member 222 having substantially the same outer shape as the fiber-reinforced concrete pipe 21, disposed at a joint 4 between the column 2 and the beam 3, and communicating with the fiber-reinforced concrete pipe 21; and concrete portion 24 filled inside the fiber-reinforced concrete pipe 21 and inside the closing member 222.SELECTED DRAWING: Figure 1 【課題】所望の充填コンクリートの拘束効果と柱のせん断伝達性能および軸力伝達性能を確保し、施工性を向上できる柱と梁との接合構造および柱と梁との接合構造の施工方法を提供する。【解決手段】コンクリート管を用いた柱２と鉄骨造の梁３との接合構造１であって、柱２は、未硬化状態のコンクリート系材料に複数の繊維を混入させた繊維補強コンクリート２１０により形成された繊維補強コンクリート管２１と、繊維補強コンクリート管２１の内部に配置され鉛直方向に延びる複数の接合鉄筋２３と、繊維補強コンクリート管２１と略同一の外形形状を有し、柱２と梁３との接合部４に配置され繊維補強コンクリート管２１に連通するふさぎ部材２２２と、繊維補強コンクリート管２１の内部およびふさぎ部材２２２の内部に充填されたコンクリート部２４と、を備える。【選択図】図１
