PRECAST FLOOR SLAB STRUCTURE AND PRECAST FLOOR SLAB
To provide a precast floor slab structure and a precast floor slab that can suppress fatigue caused in a joint when the ends of the precast floor slabs are arranged facing each other and a plurality of precast floor slabs are continuously connected via a filler to form a precast floor slab structure.SOLUTION: A precast floor slab structure 20 comprises a plurality of precast floor slabs 100 formed in a plate shape with concrete parts 101 exposed at ends 110 and reinforcement bars 102 arranged inside in a thickness direction. The precast floor slabs 100 are connected with each other with the ends 110 arranged facing each other and with a joint 25 made of a filler formed between the ends 110. A portion including a corner between the floor slab end face 110T and floor slab surface 110S is removed at each end 110 to form a chamfered portion 120.SELECTED DRAWING: Figure 4
【課題】プレキャスト床版の端部同士を対向させて配列し、複数のプレキャスト床版を充填材により連続的に接続してプレキャスト床版構造物を構成する際に、継手に生じる疲労を抑制することが可能なプレキャスト床版構造物、プレキャスト床版を提供すること。【解決手段】板状に形成されて端部１１０にコンクリート部１０１が露出するとともに厚さ方向の内方に鉄筋１０２が配置された複数のプレキャスト床版１００を備え、前記端部１１０同士を対向させて配列させるとともに前記端部１１０同士の間に充填材からなる継手２５が形成されることにより前記プレキャスト床版１００が接続されたプレキャスト床版構造物２０であって、前記端部１１０には、床版端面１１０Ｔと床版表面１１０Ｓの角部を含んで除去した面取り部１２０が形成されていることを特徴とする。【選択図】図４
