PROBLEM TO BE SOLVED: To provide a construction method of a concrete floor slab, which enables a form for the concrete floor slab to be rationally provided by effectively utilizing a cross girder arranged between steel main girders, in the construction of a steel girder bridge with a long interval between the steel main girders. SOLUTION: The cross girders 11 are arranged at intervals between the steel main girders 10 and 10 which are arranged in parallel, so that both ends of the respective cross girders can be coupled to the steel main girders. After that, temporary girders 12 for supporting timbering, which are elongated along the longitudinal direction of the main girder 10, are provided between the respective cross girders 11 and 11, and the form 19 for the floor slab is supported by the timbering 17 which is arranged on the temporary girder, so that the concrete floor slab can be placed.
