PURPOSE: A deck panel of a reinforced concrete slab is provided to prevent deflection caused by work load and the dead weight in placing concrete by installing deflection preventing devices to truss girders. CONSTITUTION: A deck panel of a reinforced concrete slab comprises a deck plate(2) with predetermined size, and plural truss girders(4) longitudinally fixed on the deck plate, with regular intervals. Deflection preventing devices are installed to the truss girder, to sufficiently support the deflection of the deck plate caused by the work load and the dead weight in placing concrete. The deflection preventing device comprises a strand(18) arranged along the longitudinal direction of the truss girder, and fixing members(20) installed to the ends of lattices constituting the truss girder. The fixing members make the truss girder and the deck plate cambered by pulling the sides of the strand to give tension stress.
