JUNCTION STRUCTURE AND JOINT METHOD FOR PRECAST REINFORCED CONCRETE MEMBERS
To suppress extrusion of cover concrete at a junction structure of precast members.SOLUTION: A junction structure of precast reinforced concrete members comprises: a plurality of precast members 10 in which reinforcement bars 30, 40 and a steel beam 50 are buried extending in an axial direction; and a junction portion 20 filled with filler to joint axial end portions of the adjacent precast members 10a, 10b with each other. The steel beam 50 partially protrudes from the axial end face of the precast member 10, while its remaining portion is buried in the precast member 10, and is positioned at the inner side of the reinforcing bars 30, 40 in the precast members 10. The steel beam 50 comprises a web portion and a flange portion having a flange surface facing the reinforcing bars. The steel beams of the adjacent precast members 10a, 10b are jointed with each other at the junction portion 20.SELECTED DRAWING: Figure 2
【課題】プレキャスト部材の接合構造物におけるかぶりコンクリートの押し出しを抑制する。【解決手段】プレキャスト鉄筋コンクリート部材の接合構造は、軸方向に延伸する鉄筋３０、４０と鉄骨５０が埋設された複数のプレキャスト部材１０と、隣り合うプレキャスト部材１０ａ、１０ｂの軸方向端部同士を接合する充填材が充填された接合部２０と、を有し、鉄骨５０は、一部がプレキャスト部材１０の軸方向端面から突出し、残部が当該プレキャスト部材１０の内部に埋設され、かつ、プレキャスト部材１０の内部において鉄筋３０、４０よりも内側に位置し、鉄骨５０は、ウェブ部と、鉄筋に対向するフランジ面を有したフランジ部と、を有し、隣り合うプレキャスト部材１０ａ、１０ｂの各鉄骨は、接合部２０において互いに接続されている。【選択図】図２
