<p><P>PROBLEM TO BE SOLVED: To provide a steel floor slab increased in strength by simplifying the filling operation for a filler into the closed section spaces of vertical rib to reduce the man-hours for filling operation for the filler by improving the maintainability, by reinforcing the steel floor slab without requiring a traffic stopping on a traveling road or by a traffic stop in a short time, and by increasing the local bending rigidity of a deck plate at both the closed spaces of the vertical ribs and the open space part between the lower surface of the deck plate and the vertical ribs to increase the strength of the steel floor slab, and also to provide a reinforcing method of the steel floor slab. <P>SOLUTION: In this steel floor slab, the vertical ribs 2 extending in the vertical direction (direction of traveling lane) of the deck plate 1 forming the floor slab of the traveling road are disposed in the lateral direction of the deck plate 1 and secured to the lower surface of the deck plate. The closed section spaces of the vertical ribs are filled with the filler 10 made of one of the fluid body of a fluid such as an elastomer material and water, a gel-like substance, and an incompressible plasmodium. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
