Description

Technical Field

[0001] The utility model relates to the field of steel structure webs, and more particularly to a steel structure web used in bridge engineering. Background Art

[0002] Steel web plays a vital role in bridge engineering. It is one of the key components of the bridge main beam or box girder structure. It is used to connect the bottom structure and top structure of the bridge. It can effectively enhance the bending performance of the bridge cross section and its ability to withstand shear loads.

[0003] Existing steel structure auxiliary plates are mostly corrugated steel webs, which are high in strength and light in weight. At the same time, their corrugated shape can provide good torsional resistance. The steel structure webs are usually connected to the main structure of the bridge to ensure the firmness of the connection. After the steel structure auxiliary plates are installed, the concrete pouring work is followed to form a complete force-bearing system.

[0004] In actual use of the existing technology, there are certain gaps at the joints of the steel structure web after installation. The presence of the gaps will weaken the continuity of the structure, reduce the overall bearing capacity and stability, and thus increase the risk of structural failure. Therefore, a steel structure web for bridge engineering is proposed. Utility Model Content
