摘要： PROBLEM TO BE SOLVED: To provide a construction method of a bridge, and a side floor slab mounting device for the bridge minimizing restrictions on construction such as traffic regulations without causing an increase in a construction cost or the extension of a construction period.
SOLUTION: A side floor slab 5 is transported into a predetermined position on a main girder 4 by a truck 6. There is thereby no need to lift the side floor slab 5 from a road by a truck crane or the like, nor need to provide an installation space and a working space for the truck crane or the like. In mounting the side floor slab to the side of the main girder 4, the side floor slab 5 is conveyed by a conveying device 13 of the side floor slab mounting device 10, and the fall of the side floor slab 5 is prevented by a fall preventive structure 14. There is thereby no need to limit passing of persons and vehicles below the side floor slab 5 during fixing work. Restrictions on traffic regulations or the like can thereby be minimized on the road or the like below and in a surrounding area below an upper construction 1B under construction, and restrictions on construction can be considerably relieved.
