JUNCTION STRUCTURE AND JUNCTION METHOD OF PRECAST MEMBER
To provide a junction structure and a junction method of a precast member that can join the precast member in a short period of time without temporary provision of load support, and prevent a precast product after joining from opening at a joint part when a large-scale earthquake occurs.SOLUTION: In the junction structure of at least two precast members connected in series, the at least two precast members are joined by pressure welding between the precast members by PC steel strained through all precast members, a mortar filling joint in which ends of both steel bars embedded in adjacent precast members are fixed through mortar filled in a common sleeve, and a shear key formed on both end faces of the adjacent precast members.SELECTED DRAWING: Figure 4
【課題】プレキャスト部材を短期間で且つ荷重支えを仮設することなく接合できるようにし、接合後のプレキャスト製品が大規模地震時に接合部で目開きを起こさないようにする。【解決手段】直列に連なる少なくとも２つのプレキャスト部材の接合構造において、前記少なくとも２つのプレキャスト部材が、全プレキャスト部材を貫通して緊張したＰＣ鋼材によるプレキャスト部材間の圧接と、隣接するプレキャスト部材に埋設した両鉄筋の端部を共通のスリーブ内に充填したモルタルを介して固定したモルタル充填継手と、隣接するプレキャスト部材の両端面に形成したせん断キーとにより接合されている。【選択図】図４
