The invention discloses a steel truss girder bolt screwing operating platform. The steel truss girder bolt screwing operating platform comprises a pair of supports in relative butt joint and a connector connecting the pair of supports into integrity; each support comprises multiple longitudinal rods forming the support body structure and accessories arranged among the longitudinal rods; the side, used for butt joint, of each support is defined as a support inner side, the other side relative to the support inner side is a support outer side, and each accessory comprises jackings with a preset quantity and arranged at the upper half part of the support inner side. The steel truss girder bolt screwing operating platform has the advantages of being simple in structure, fast to assemble, and convenient to carry, the platform can be constructed on a bridge according to characteristics of the bridge, completely breaks the limit that the operating platform must be constructed from the ground previously, and thus the steel truss girder bolt screwing operating platform has good environment adaptability.
