METHOD OF CONSTRUCTING COMPOSITE STEEL FLOOR SLAB BRIDGE, STEEL FLOOR SLAB WITH RIB, AND COMPOSITE STEEL FLOOR SLAB BRIDGE

PROBLEM TO BE SOLVED: To solve problems of a conventional composite steel floor slab wherein, despite the fact that the height of a girder is reduced by using vertical ribs for both dowel and main girder functions, the installation of horizontal ribs on the lower surface of the steel floor slab invades a space under the bridge, and the horizontal ribs take labor for painting after the start of use of the bridge in addition to a labor for installation, which is one of the reasons of an increase in maintenance cost. SOLUTION: In this steel floor slab with ribs which constitutes a composite steel floor slab, a plurality of vertical ribs disposed in parallel or generally in parallel are fixed to one surface of a steel plate, a plurality of horizontal ribs disposed perpendicular or generally perpendicular to the vertical ribs are fixed to the surface of the steel plate to which the vertical ribs are fixed, and the vertical ribs and the horizontal ribs are disposed on and fixed to one surface of the steel plate in a lattice shape.
