Description

Technical Field

[0001] This utility model relates to the field of bridge technology, and in particular to a curved surface forming device for steel structure bridges. Background Technology

[0002] A bridge is an architectural structure that connects two locations and is typically used to cross obstacles such as rivers, roads, and railways. A steel structure bridge is a bridge that primarily uses steel as its structural material. Certain regions may require curved bridges based on specific needs. Curved surface forming equipment is a type of machine used to create curved shapes.

[0003] As described in the prior art patent application CN 220177916 U, a support plate is fixedly installed on the top of the base, and grooves and slides are provided on the side walls of the support plate, with connecting blocks installed in the grooves. This invention uses adjusting bolts to move the upper pressure column, which in turn causes the first flexible plate to form the same arc surface as the required bridge. Then, a rotating screw moves the slider, which in turn moves the lower pressure column, causing the second flexible plate to form the same arc surface as the required bridge. The bridge material to be pressed is placed between the first and second flexible plates, and a cylinder moves the connecting block, which in turn moves the moving plate, thus moving multiple upper pressure columns. This allows the upper pressure columns to extrude and form the steel plate material, thereby reducing the time spent on replacements and accelerating the production of curved surface bridges.

[0004] However, when the device is forming the steel plate, it cannot limit the position of the steel plate. The unevenness of the surface of the flexible plate can easily cause the steel plate to move, thus affecting the forming effect of the steel plate.
