PURPOSE: A precise concrete panel is provided to reduce stress toward a girder using block grooves of a panel main body lower part. CONSTITUTION: A main body(110) includes a block groove(120) of square shape. A first steel reinforcement bar(130) is apart from both ends of the longitudinal direction of the main body as a fixed length. The first steel reinforcement bar is buried in the main body. A second steel reinforcement bar is horizontally buried inside the main body along the short direction of the main body. A third steel reinforcement is buried in the space between both sides of the main body longitudinal direction and the block groove. |
