Construction Technology of Steel Structure Bridges
1. Factory prefabrication and on-site assembly
The components of steel structure bridges are usually prefabricated in factories and then transported to the site for assembly. This construction method can ensure the accuracy and quality of components, reduce the complexity and uncertainty of on-site construction.
2. Welding and bolted connections
The main connection methods for steel structures are welding and bolt connection. Welding has high strength and sealing, but requires a high level of technical expertise; Bolt connections have the advantages of convenient construction and flexible disassembly, making them suitable for occasions that require frequent disassembly and assembly.3. Lifting and Installation Technology
The hoisting and erection of steel structure bridges are key links in construction. The use of large lifting equipment can ensure accurate positioning and safe installation of bridge components. In addition, it is necessary to strictly control the lifting process to ensure construction safety and quality
4. Anti corrosion and fire prevention treatmentSteel is susceptible to corrosion and fire during long-term use, therefore it is necessary to carry out anti-corrosion and fire prevention treatment on steel structure bridges. Common anti-corrosion methods include painting, hot-dip galvanizing, etc; Fireproof treatment can be achieved by spraying fireproof coatings or setting up fireproof isolation layers.
