JUNCTION STRUCTURE OF PRECAST COMPOSITE FLOOR SLAB PANEL AND JUNCTION METHOD OF PRECAST COMPOSITE FLOOR SLAB PANEL
To provide a junction structure of precast composite floor slab panels that can reduce a construction time and cost, and prevent components from falling.SOLUTION: The junction structure of precast composite floor slab panels comprises a pair of precast composite floor slab panels 10 and joint parts 20 in which concrete is cast on site between the pair of precast composite floor slab panels 10. The precast composite floor slab panel 10 includes a bottom steel plate 11, reinforcement materials 12, anchorage devices 13 for fixing concrete to the bottom steel plate 11, a base part 14 made of reinforcing bars and concrete and connecting ribs 15 erected at both ends of the upper surface of the bottom steel plate 11 in the bridge axis direction. The joint part 20 includes a cast-on-site concrete part 24 formed by casting concrete on site together with the reinforcing bars extending from each adjacent base part 14, and the connecting ribs 15 facing each other are joined by bolts B via connection plates 21.SELECTED DRAWING: Figure 1
【課題】工期の短縮、工費の削減及び部材の落下防止を図ることができるプレキャスト合成床版パネルの接合構造を提供する。【解決手段】一対のプレキャスト合成床版パネル１０と、一対のプレキャスト合成床版パネル１０の間において現場でコンクリートが打設された継手部２０と、を有し、プレキャスト合成床版パネル１０は、底鋼板１１と、補強材１２と、底鋼板１１にコンクリートとを定着させる定着具１３と、鉄筋及びコンクリートで形成された基体部１４と、底鋼板１１の上面の橋軸方向の両端に立設する連結用リブ１５と、を備え、継手部２０は、隣り合う各基体部１４から延設された鉄筋とともに現場でコンクリートを打設して形成された現場打ちコンクリート部２４を備え、かつ、対向する連結用リブ１５同士が、連結プレート２１を介してボルトＢで接合されていることを特徴とする。【選択図】図１
