PROBLEM TO BE SOLVED: To provide a steel deck plate and a method for reinforcing it, in which steel deck plates are reinforced by injecting fillers into the closed sectional spaces of their longitudinal ribs through simplified injection/filling operations, reducing their required man-hour and improving plate deck maintenance ability, without the need for or with only a short-time traffic shut-off, and also by increasing the local bending rigidity of deck plates in both areas of closed spaces in their longitudinal ribs and open spaces between their bottom surfaces and longitudinal ribs. SOLUTION: In the steel deck plate, composing a carriageway, where a plurality of longitudinal ribs extending (in the car running direction) and formed as as to be closed in section are arranged across the breadth of the deck plate and fixed to its bottom surface, it is so prepared that fillers made of an elastomer, a fluid such as water, either a fluid such as gelled materials, etc. or a non-compressive deforming material are filled in the closed sectional spaces of the longitudinal ribs.
