Description

Technical Field

[0001] The invention discloses automatic assembly equipment for U-rib-plate rib of bridge, belonging to the field of production equipment for steel structure bridge. Background Art

[0002] Steel structure bridges have a history of more than 200 years. Their development is closely related to material technology, manufacturing technology, and structural design. In terms of structural design, steel trusses or steel plate beams were used in the early days. Since the mid-20th century, with the increasing maturity of orthogonal anisotropic thin-walled steel box girder structural design and the improvement of welding technology, steel box girder structures have become the main structural form of steel bridge decks due to their low height, light weight, high rigidity, high ultimate bearing capacity, easy processing and manufacturing, and good structural continuity.

[0003] The orthotropic bridge deck is mainly composed of a steel structure panel and the cross beams and longitudinal ribs welded thereto. The cross beams are mainly diaphragms, and the longitudinal ribs are U-shaped ribs or plate rib structures. Since U-shaped ribs or plate ribs can provide greater torsional and bending stiffness, they can improve the stress state of the entire bridge deck, and thus become the most commonly used cross-sectional form of modern orthotropic bridge decks.

[0004] U-shaped ribs and plate-shaped ribs are fixed inside the crossbeams of the bridge. At the same time, during processing and assembly, the burrs on the edge of the bottom plate need to be polished and removed to prevent affecting the welding quality between the ribs and the bottom plate.
