PROBLEM TO BE SOLVED: To provide a concrete slab form mounting method capable of being easily detached and increasing the rigidity of a holding beam in a girder for supporting a concrete slab by using a simply member in two main girder bridges having a wider interval between main girders. SOLUTION: A bridge axial lower supporting beam is mounted on a cross girder, a supporting post is provided to the lower supporting beam, an upper supporting beam is mounted on the supporting post, a cross supporting beam supporting both ends on the upper supporting beam and an upper flange of the main girders is provided, and the concrete slab form is mounted on the cross supporting beam. A deformation preventive beam restraining the lateral deformation of the main girders is mounted on the lower supporting beam. A working scaffold is mounted on the lower supporting beam.
