In the prior art, the beam is provided with a plurality of support bases for supporting the steel box girder. Since the pressure applied to each support base is different during the placement process of the steel box girder, the surface of the beam may have different degrees of subsidence , causing the support bases to be out of plane, or the plane where the support bases are located to be tilted, resulting in the deviation of the placement of the steel box girder, and even safety accidents such as overturning in severe cases

The invention relates to the technical field of bridge construction, in particular to a temporary consolidation structure for a steel box girder. The structure comprises a cross beam, a steel box girder is arranged at the upper end of the cross beam, a plurality of temporary supporting seats are arranged between the steel box girder and the cross beam, at least one base is arranged between the temporary supporting seats and the cross beam, and a plurality of temporary supporting seats are arranged on each base. In the structure provided by the invention, the plurality of temporary supporting seats are arranged between the cross beam and the steel box girder, the at least one base is arranged between the temporary supporting seats and the cross beam, and the plurality of temporary supporting seats are arranged on each base, so that the pressure of the steel box girder on the temporary supporting seat on each base is transmitted to the corresponding base. The base can evenly apply the borne pressure to the cross beam, deformation caused by the fact that the cross beam is locally stressed by large pressure is effectively avoided, the upper surfaces of the temporary supporting seats are guaranteed to be located in the same plane, the plane where the temporary supporting seats are located is parallel to the cross beam, deviation of the position of the steel box girder is avoided, and the installation safety of the steel box girder is improved.
Description
technical field [0001] The present disclosure relates to the technical field of bridge construction, in particular to a temporary consolidation structure of a steel box girder. Background technique [0002] With the large-scale construction of highways and railway transportation networks in my country, the construction of long-span cable-stayed bridges also appears frequently. Due to the light weight of steel box girders and good spanning performance, long-span cable-stayed bridges are all made of steel box girders. Main girder structure, steel box girder cantilever installation and construction will also be the most common construction method in the main girder construction of long-span cable-stayed bridges. During the installation and construction of the steel box girder cantilever, the girder crane lifts the steel box girder and places it on the beam. [0003] In the prior art, the crossbeam is provided with a plurality of support seats for supporting the steel box girder...
