Description

Technical Field

[0001] The utility model relates to the technical field of steel box girders, in particular to an auxiliary installation tool for steel box girders. Background Art

[0002] Steel box girder, also known as steel plate box girder, is a commonly used structural form for large-span bridges. It is generally used on bridges with larger spans. It is called a steel box girder because of its box-like appearance. Steel box girder is generally composed of top plate, bottom plate, web plate, transverse diaphragm, longitudinal diaphragm and stiffening ribs connected by full welding. The top plate is an orthogonal anisotropic bridge deck composed of a cover plate and longitudinal stiffening ribs.

[0003] Since steel box girders have a large span and heavy weight, it takes a long time to build a bridge. If the road is directly controlled to build the bridge, it will affect the normal traffic for a long time. If the steel box girder is assembled and transferred to the target section, more auxiliary equipment will be required. The existing auxiliary equipment is generally large in size, inconvenient to transport, and troublesome to install and disassemble.

[0004] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content
