Description

Technical Field

[0001] This utility model relates to the field of steel box girder technology, specifically a spliced ​​anti-deformation steel box girder. Background Technology

[0002] Steel box girders are a type of bridge structure commonly used in bridges with long spans. Also known as steel plate box girders, they are a common structural form for long-span bridges. They are generally used in bridges with large spans and are called steel box girders because of their box-like shape. Steel box girders are formed by fully welding the top plate, bottom plate, web, transverse diaphragms, longitudinal diaphragms, and stiffeners. The top plate is an orthotropic bridge deck, composed of a cover plate and longitudinal stiffeners. The advantages of steel box girders include their good mechanical properties, durability, and ease of maintenance, making them widely used in the construction of long-span bridges. Currently, steel box girders are generally manufactured using splicing methods. The structures of spliced ​​steel box girders are often unstable, potentially posing many safety risks. Therefore, those skilled in the art have provided a spliced, deformation-resistant steel box girder to address the problems mentioned in the background section. Utility Model Content
