Wall Structure Using Precast Concrete Panel with Multi Rib Rows

A slab structure using a multi-rib type precast concrete panel is provided to make the construction of a long span possible at the unsupported state, and to reduce the period and cost of construction by keeping the lower part clean and emitting the finish work for a ceiling. A slab structure using a multi-rib type precast concrete panel contains: a multi-rib type precast concrete panel(100) provided with a base panel(110), reinforcing ribs(120) arranged on one side of the base panel in many rows and anchor wires(130) projected to the outside of a panel and coupled with a slab bar(220) buried under toping concrete; and toping concrete(200) placed on the upper part of the multi-rib type precast concrete panel. Filter blocks are installed in the multi-rib type precast concrete panel to fill a space between reinforcing ribs.
