PURPOSE: A cantilever of a steel box bridge slab using permanent steel pedestals and a construction method thereof are provided to prevent accidents caused by high-place work and to enable quick and smooth construction of a cantilever. CONSTITUTION: A cantilever of a steel box bridge slab comprises a plurality of permanent steel pedestals(200), joists(300), a working passage(400), and a precast deck(500). The permanent steel pedestals, one side of which is coupled to the side of a steel box girder(10), protrude from the side of the steel box girder and arranged at regular intervals in the longitudinal direction of the steel box girder. The joists are fixed to the other side of the permanent steel pedestals and connect the permanent steel pedestals in the longitudinal direction of the steel box girder. The working passage is coupled to the other end of the permanent steel pedestals and protrudes from the side of the permanent steel pedestals, thereby allowing the passage of a worker in construction of a cantilever. The precast deck is installed to be placed on the permanent steel pedestals and the joist and allows the placement of concrete on a cantilever. |
