PURPOSE: A construction method of concrete slab is provided to construct the concrete slab without a mold in the construction field of a bridge by constructing concrete and PC(Pre-cast Concrete) when constructing a girder plus concrete slab bridge. CONSTITUTION: A construction method of concrete slab contains the steps of: installing a girder, dividing a concrete slab as the thickness of the slab up and down, manufacturing the lower part with PC plank, carrying to a position of a bridge, installing on the girder, distributing bars, and installing the upper part of the slab. This method is safe and economic due to unnecessary molding work in a high place and prevents an eruption accident while installing concrete.
