[0002] During the production of steel box girders, a large number of them have large cross-sections and irregular trapezoidal structural sections. Furthermore, the project requires minimizing on-site welding. Therefore, it is extremely important to produce an external formwork frame and control the external dimensions during the assembly process. However, since the cross-sectional width, height, and flange angle of the steel box girder are numerous and difficult to standardize, the conventional frame production method consumes a large amount of profiles and auxiliary materials, resulting in poor economic benefits and being time-consuming and labor-intensive. To address this need, an adjustable support structure has been developed to achieve adjustable width, height, and angle of the frame, ensuring its reusability, improving production efficiency, reducing steel consumption, and increasing economic benefits.

DETAILED DESCRIPTION

[0013] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0014] The utility model provides Figures 1-4 The adjustable support structure for manufacturing a steel box girder shown includes a bottom module and a steel box girder 200. The bottom module includes a bottom module top plate 100, a bottom module bottom plate 110, a bottom module web 120 and a stiffening plate 130. The bottom module web 120 is placed between the bottom module top plate 100 and the bottom module bottom plate 110. The stiffening plate 130 is welded to the front and rear sides of the bottom module web 120 and is at the same height as the bottom module web 120. The bottom plate of the steel box girder 200 is placed in the middle of the bottom module top plate 100. The bottom module top plate 100 has two oblong holes 140 symmetrically arranged on the left and right sides of the bottom plate of the steel box girder 200, and an adjustment device is symmetrically arranged on the left and right sides of the bottom module top plate 100.

[0015] Among them, the adjustment device includes a connecting plate 300, which is provided with four circular holes 310 corresponding to the two oblong holes 140 on one side.
