Abstract
The utility model relates to the technical field of steel box girders, in particular to a positioning splicing type steel box girder which comprises a girder top plate, a girder base is fixedly connected to the outer wall of the bottom end of the girder top plate, an inserting groove is formed in the outer wall of one side of the girder top plate, and an inserting plate is fixedly connected to the outer wall of the other side of the girder top plate. The outer wall of the other side of the top of the beam base is fixedly connected with a first telescopic plate, the outer wall of the other side of the bottom of the beam base is fixedly connected with a second telescopic plate, one end of a piston plate of each of the first telescopic plate and the second telescopic plate is fixedly connected with a trapezoidal frame, and a trapezoidal groove is formed in the outer wall of one side of the beam base. According to the splicing structure, splicing in the horizontal direction is completed through the inserting plates and the trapezoidal frames, connection in the horizontal direction can be completed through the inserting plates and the trapezoidal frames during splicing of the steel box girders, longitudinal connection can be completed through descending and inserting of the pressed plates and the limiting plates into the trapezoidal frames, the structure is more stable, and the splicing structure is not prone to skewing to generate gaps; and the use efficiency of the steel box girder is improved.
