During the design process, the appearance of bridge towers varies, so the utilization rate of variable-section bridge towers has gradually increased. As the height of the tower limbs increases, the dimensions of each section of the variable-section bridge towers continue to change, and the spacing of the steel mesh inside them changes. During the construction process, the assembly and welding of the steel mesh of the variable-section bridge tower has become a thorny problem. At the same time, the investment in steel mesh for high bridge towers is large. If the entire tower column is welded manually, it will lead to problems such as large construction workload, long operation time, and poor economic benefits.

[0003] In the related art, there is a manufacturing frame for steel mesh, which includes a placement frame, and the placement frame includes a horizontally placed support plate, on which a plurality of vertically arranged vertical rods are arranged at intervals along the length direction, and on which a plurality of cross rods are arranged at intervals along the vertical direction, and the cross rods are rotatably connected to the vertical rods, and the cross rods and the vertical rods are used to manufacture the vertically placed steel mesh. Although the manufacturing frame changes the angle of the cross rods by means of a control spring arranged under the support plate to facilitate the placement and removal of the steel mesh when welding the steel mesh and after welding, manual operation is still required to move the steel bars to the position where welding is required or to transport the steel mesh after welding; in addition, the manufacturing frame can only weld simple quadrilateral steel meshes, and is not applicable to steel meshes with variable cross-sections.
