Claim:
A construction method of a steel composite girder bridge, the method comprising: installing steel girders on piers and forming shearing connectors continuously on the steel girders at intervals of a predetermined distance; installing stagings and a first form for casting deck concrete in the steel girders; installing non-composite members in an upper flange of the steel girders to form each non-composite section of supporting points and installing a second form around each of the shearing connectors, wherein the second form forms a shearing pocket; arranging sheath pipes in the supporting points and forming supporting point decks by casting and curing concrete; applying pre-stress to each section of the supporting point decks through the sheath pipes and performing a grouting process; forming span decks adjacent to the supporting point decks by casting and curing concrete in each span between the piers; filling the shearing pockets with non-shrinkage mortar; and forming a road after dismantling the stagings and the first and second forms, and forming protection walls.
