Project description

The Qingshan Road pedestrian overpass is a thin-walled closed box section continuous steel beam with a span of 35 meters, which overcomes the adverse environment of numerous underground and aboveground pipelines, and completes the construction of the pedestrian overpass as planned under the condition of ensuring smooth traffic, making contributions to the human-machine separation of Qingshan Road traffic.

 

Steel structure is composed of steel materials and is one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of section steel and steel plates, and rust removal and rust prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing are adopted. Welds, bolts or rivets are usually used to connect members or components. Because of its light weight and simple construction, it is widely used in large workshops, stadiums, super high-rise buildings and other fields. The steel structure is easy to rust. Generally, the steel structure shall be derusted, galvanized or coated, and regularly maintained.
