Precast Concrete Deck for Long-Span Slab and the Slab using it

摘要

The present invention relates to a precast concrete deck for a long-span slab, and a slab using the same. According to an embodiment of the present invention, a precast concrete deck for a long-span slab is characterized such that at least one first strand is fixated to a bottom of a rib to penetrate a bottom plate portion while at least one second strand shorter than the first strand is fixated to an upper portion of the first strand to penetrate the rib, and negative bending moment generating on both ends being able to be reduced; thereby preventing an occurrence of a crack by preventing the precast concrete deck from exceeding bending and cracking strength.
