High-strength bolts and welding are the main methods of connecting steel bridges. The high-strength bolt connection is simple and detachable in construction, which can ensure the reliability

of the connection. It is widely used in the splicing of steel beam segments, the connection of bridges and piers, etc. During construction, the pre-tightening force of the bolts is accurately controlled to

make the connection closely fit and transmit the load. Welding can form a continuous and rigid connection. In some parts that require extremely high integrity, such as welds on steel box girders,

it can ensure seamless connection of the structure, reduce stress concentrations, and improve the overall performance of the structure.

Product Advantages

Fast construction speed: The combination of factory prefabrication and on-site assembly greatly shortens the construction period of steel structure bridges. Compared with concrete bridges, which require a long time for concrete pouring, maintenance and other processes, steel structure bridges can quickly complete component installation and be put into use as soon as possible. For example, some emergency disaster relief bridges or temporary construction bridges often adopt steel structures that can be built in a short time to meet transportation needs.

Product Application

Railway transportation: Railway bridges have extremely high requirements for structural rigidity and stability. Steel structure bridges play an important role in railway construction due to their high strength and good mechanical properties. Especially in the construction of high-speed railways, steel structure bridges can meet the strict requirements for bridge deformation control when high-speed trains are running. For example, some high-speed rail bridges across rivers and cross-sea in my country adopt steel structure design to ensure the safe and smooth operation of high-speed trains.
