<p>The present invention relates to an inverted rib slab for precast concrete (PC) structure. The PC inverted rib slab includes an upper protruding support rib of a structure with an inverted t-shape. As the slab is a flat plate, ceiling finishing work is simply performed, and a finishing work including facility construction can be easily conducted. Thus, costs for insulation can be reduced (when a cold storage is constructed). An effective space is expanded due to the flat ceiling surface, and a connection unit between plates (slabs) has a large effective depth of a topping concrete (T/C) in order to remarkably reduce cracks. Moreover, the continuity and integrity of a bonding unit between the slabs are excellent, and productivity and economic feasibility can be obtained through the cost reduction due to the reduction of a cross section.</p> |
