TADOKORO TOSHIYA / NAKATA HIROKI / NISHIO YUGO

To suppress extrusion of the 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 are buried extending in an axial direction; a junction part 20 filled with filler to joint axial end parts of the adjacent precast members 10 with each other; and an unfixed part 50 where the reinforcing bars are not fixed to the concrete. The unfixed part 50 extends from the inside of an adjacent first precast member 10a to the inside of a second precast member 10b.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１０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、鉄筋がコンクリートに定着していない非定着部５０と、を有し、非定着部５０は、隣り合う第１のプレキャスト部材１０ａの内部から第２のプレキャスト部材１０ｂの内部まで延びている。【選択図】図２
