Steel is an essential material for national construction and the realization of the four modernizations. It is widely used and comes in various types. According to the different cross-sectional shapes, steel is generally divided into four categories: profiles, plates, pipes, and metal products. To facilitate the organization of steel production, ordering, and supply, effective management is necessary. A utility model patent for a U-shaped steel plate structure features an integrally formed base plate and side plates, with evenly spaced bottom holes on the base plate, having more than one bottom hole. The base plate has two side plates symmetrically located at both ends, with side holes on the side plates, having more than one side hole. The side has connecting bolts that link the U-shaped steel plate structure to the bridge, effectively connecting the beam and limiting the lateral displacement of the beam. The base plate of the U-shaped steel plate structure is connected to the upper support plate of the bridge support using high-strength bolts, reinforcing the bridge.

To adapt to the rapid development of the modern transportation industry, bridges have also extended to constructions that span gorges, areas with poor geology, or meet other transportation needs, making transportation more convenient. Today, old bridges from the 70s and 80s are still in use. Many old bridge supports are connected using embedded steel plates within the bridge beams. Similar to bridges, U-shaped steel is also widely used in construction, but currently, many U-shaped steels are limited to single-layer structures with restricted structural strength. Therefore, a new type of high-strength U-shaped steel structure has been designed.

To overcome the shortcomings of existing technical solutions, this utility model provides a new type of high-strength U-shaped steel structure that can effectively solve the problems brought by the background technology. The technical problem to be solved by this utility model is: a new type of high-strength U-shaped steel structure, including a U-shaped steel main body, with clamps set on the inner wall of the U-shaped steel main body, and U-shaped steel reinforcing ribs inside the clamps. The ends of the U-shaped steel reinforcing ribs are equipped with fixed nuts, and the outer part of the U-shaped steel main body has protruding slots, which contain external reinforcing pads and fastening bolts. The external reinforcing pad includes an arc-shaped main plate, which has multiple columnar reinforcing ribs inside, and the end of the arc-shaped main plate is equipped with fixed clamping strips, which have positioning screw holes. The upper end of the arc-shaped main plate has a wedge-shaped groove, into which anti-slip strips are inserted. Additionally, a protective pad is placed between the U-shaped reinforcing ribs and the U-shaped steel body, made of polyurethane material. Furthermore, the clamps are evenly spaced on the inner wall of the U-shaped steel body. The anti-slip strips are made of silicone rubber material.
