PRECAST PRESTRESSED CONCRETE FLOOR SLAB STRUCTURE AND CONSTRUCTION METHOD FOR THE SAME
To provide a floor slab structure and a construction method for the same that can suppress cracks in a concrete section near an expansion device without using a PCa member extending in an oblique direction in a precast prestressed concrete floor slab structure arranged at an end fulcrum of an abutment having an oblique angle with respect to the bridge axis direction and a construction method for the same.SOLUTION: A floor slab structure 1 includes: a plurality of ramp PCa members 6 extending in the bridge width direction; and oblique tension members 7 inserted into all of the ramp PCa members 6 in the vicinity of an expansion device 3. The ramp PCa members 6 are adjacent to each other in the bridge axis direction and have oblique sides 11 extending along the expansion direction of the expansion device 3 in the vicinity of the expansion device 3 in a plan view.SELECTED DRAWING: Figure 1
【課題】橋軸方向に対して斜角を有する橋台の端支点に配置されたプレキャストプレストレストコンクリート床版構造及びその構築方法において、斜め方向に延在するＰＣａ部材を使用せず、伸縮装置の近傍のコンクリート部分にひび割れが生じることを抑制できる床版構造及びその構築方法を提供する。【解決手段】床版構造１は、橋幅方向に延在する複数の傾斜部ＰＣａ部材６と、伸縮装置３の近傍で傾斜部ＰＣａ部材６の全てに挿入された斜め方向緊張材７とを備える。傾斜部ＰＣａ部材６は、互いに橋軸方向に隣接し、平面視で伸縮装置３の近傍で伸縮装置３の延在方向に沿って延在する斜辺１１を有する。【選択図】図１
