PROBLEM TO BE SOLVED: To provide a construction method for a composite floor panel enabling the joining work of a floor panel from a lower face for conventional work from a bridge face, to solve problems of traffic regulations and the prolongation of a construction term. SOLUTION: The floor system panel constituting the composite floor panel is composed of an upper steel plate 1, a plurality of section steels 2 arranged in parallel at required intervals on the lower face of the upper steel plate 1, and a bottom steel plate 3 connecting the section steels 2 to one another to cope with a short-term traffic load by only a steel hull. A plurality of bolt holes 9 are formed in a joint plate 5 at the end of the floor system panel in advance. A bolt 6 is attached to the bolt hole 9 from an opening formed on the bottom face side of the floor panel on a main girder 15 supporting the end of the floor system panel and is tightened with a nut to join the floor panels. Then, a haunch member 4 is attached between the upper part of the main girder 15 and the bottom steel plate 3 of the floor panel from below to block the opening, and a filler is filled into the floor panel.
