CONSTRUCTING METHOD OF STEEL-CONCRETE COMPOSITE FLOOR SLAB FOR HIGHWAY BRIDGE

PURPOSE: To manufacture a simple strong concrete floor slab for a highway bridge by a factory-produced panel made of steel. CONSTITUTION: First reinforcing materials 3 consisted of a plurality of L-steel are welded zigzag onto a steel plate while a plurality of second reinforcing members 4 are welded onto the first reinforcing materials 3 as being crossed with the first reinforcing materials 3, thus manufacturing a panel 1 made of steel. The panel 1 is disposed onto a main girder 8. Reinforcements are arranged onto the panel 1, horizontally falling preventive materials are fixed onto the second reinforcing materials 4, and concrete is placed up to the intermediate sections of the reinforcing materials 4. The horizontally falling preventive materials 5 are removed, and residual concrete is placed.
