PURPOSE: Incremental launching equipment for constructing a concrete upper slab of a composite bridge using air wheels is provided to construct a bridge by consecutively installing segment structure in a work place without using supporting posts, thereby improving safety and ease of work. CONSTITUTION: Incremental launching equipment for constructing a concrete upper slab of a composite bridge comprises a launching device which consecutively launches upper slab segments, manufactured in a launching site behind an abutment and consecutively provided, at the top of a steel box girder(200); a rotary fixing plate(220) attached to the steel box girder; a steel rotary shaft(520) which is installed and fixed in the rotary shaft fixing plate; and air wheels(510) which are coupled to the steel rotary shaft and moves the upper slab segments in the launch direction.
