HALF PRECAST CONCRETE SLAB FOR THE REDUCTION OF TOPPING CONCRETE AND THE EFFICIENT USE OF A SPACE CAPABLE OF MAINTAINING STRUCTURAL STABILITY

摘要

PURPOSE: A half precast concrete slab for the reduction of topping concrete and the efficient use of a space is provided to efficiently use the space of the slab by previously forming a duct.;CONSTITUTION: A half precast concrete slab for the reduction of topping concrete and the efficient use of a space comprises a flat plate(11), multiple ribs(12), through paths(P), and concave-convex parts. The ribs are parallelly arranged on the top surface of the flat plate in a direction at uniform intervals. The through paths are formed by partition walls(13) installed between the ribs. The concavo-convex parts are formed on the top surfaces of the ribs.;COPYRIGHT KIPO 2011
