Steel box girder construction platform and using method

Abstract

The invention relates to a steel box girder construction platform and a using method. The construction platform is erected on the upper part of a steel box girder for use and comprises an L-shaped frame body arranged on a flange of the steel box girder, a horizontal section of the L-shaped frame body is arranged above the flange of the steel box girder, a vertical section of the L-shaped frame body is arranged on the horizontal outer side of the flange of the steel box girder, an operation platform is arranged at the bottom of the vertical section of the L-shaped frame body, and a guide rail is arranged on the upper surface of a top plate of the steel box girder on the flange of the steel box girder. The steel box girder construction platform can replace a traditional scaffold, a highwayaerial work vehicle and an automobile crane hanging basket, can reduce the labor intensity of workers and improve the construction efficiency of the steel box girder, can be repeatedly used, and belongs to a novel aerial work construction platform.

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to a steel box girder construction platform and a use method. Background technique [0002] As the country vigorously promotes prefabricated buildings, steel structure bridges have fast construction speed, high processing precision, and superior tensile performance. Long-span steel box girders are more and more widely used in municipal transportation projects. The traditional craft segmental and segmental fracture welding, painting, installation of drainage pipes, installation and fastening of bolts and other constructions are generally completed by erecting scaffolding, road aerial work vehicles, car cranes and hanging baskets. It is more labor-intensive to set up scaffolding or add hanging baskets. And increase the construction cost, if once run into the poor surrounding environment that is not conducive to setting up scaffolding, it will be troublesome to set up, and ...

Problems solved by technology

The traditional craft segmental and segmental fracture welding, painting, installation of drainage pipes, installation and fastening of bolts and other constructions are generally completed by erecting scaffolding, road aerial work vehicles, car cranes and hanging baskets. It is more labor-intensive to set up scaffolding or add hanging baskets. And increase the construction cost. If the surrounding environment is not conducive to erecting scaffolding, it will be troublesome to erect. The above problems need to be improved urgently
