Description

Technical Field

[0001] The utility model relates to the technical field of welding tools, in particular to a welding U-shaped stiffening rib support device based on the hydraulic principle. Background Art

[0002] The box girder bridge is a common bridge structure form. The U-shaped stiffening rib in the box girder bridge refers to the stiffening rib whose cross-sectional shape presents a "U" shape. The U-shaped stiffening rib is distributed along the longitudinal direction of the bridge by welding or connecting with the bridge box girder or main girder to increase the support and strengthening ability of the bridge structure. However, the existing welding methods often need to carry out welding on the bridge beam body, and the stress and deformation introduced during the welding process cannot be predicted. This may lead to an incomplete match between the welded stiffening rib and the bridge structure, thereby affecting the overall performance and stability of the bridge. Furthermore, the thermal stress during the welding process and the shrinkage after cooling may cause stress concentration around the welding point. This may have a negative impact on the strength and durability of the welded connection and may lead to the occurrence of cracks or damages, reducing the stability. Content of the Utility Model
