Durable Prefabricated Steel Structure Bridge Metal Modular Frame
Building
product description
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.
