PRECAST BLOCK, CONCRETE STRUCTURE, AND CONSTRUCTION METHOD FOR CONCRETE STRUCTURE
PROBLEM TO BE SOLVED: To provide a precast block and the like, which suppress cracking by reducing the amount of concrete placement and which can secure integration of a concrete structure in itself and integration between the concrete structure and a lower layer.SOLUTION: When pedestal concrete 15 is constructed in water, a precast block 1 is installed within a form 17, and underwater nonseparable concrete 19 is placed within the form 17. The precast block 1 has leg parts 5 provided on the bottom of a cylindrical body 2, and a surface thereof is roughened. Additionally, an upward inclination from an outside to an inside is provided on a bottom surface 7 between leg parts 5 of the body 2.
【課題】コンクリートの打設量を減らすことでひび割れを抑制し、コンクリート構造物自体の一体性やコンクリート構造物と下層との一体性も確保可能なプレキャストブロック等を提供する。【解決手段】水中に台座コンクリート１５を構築する際に、プレキャストブロック１を型枠１７内に設置して、型枠１７内に水中不分離性コンクリート１９を打設する。プレキャストブロック１は、筒状の本体２の底部に脚部５を設けたものであり、その表面には目粗しが施される。また、本体２の脚部５の間の底面７には、外側から内側へと上向きの傾斜が設けられる。【選択図】図２
