Prefabricated Bridge Steel Structure Building Construction Customized

Professional Steel Structure Manufacturer For Prefabricated Bridge Building

product description

The main beam is a key component of a steel structure bridge that bears vertical loads. Common forms include steel plate beams and steel box beams.

The steel plate beam consists of upper and lower flange plates and webs, which are connected by welding or riveting. The flange plate mainly withstands tensile force and

pressure, and the web resists shear force. Its structure is relatively simple, easy to manufacture and install, and is widely used in small and medium-span bridges.

Steel box girders are welded into a closed box cross-section by multiple steel plates. They have excellent spatial stress properties and high bending and torsional rigidity.

They are suitable for long-span bridges. For example, the main bridge of the Sutong Yangtze River Bridge adopts steel box girder structures, effectively responding to

the large-span challenges of the kilometer level.

Product Advantages

Strong spanning ability: The high strength of steel allows steel structural bridges to achieve larger spans. Compared with bridges made of other materials such as concrete, they have advantages when spanning wide rivers, straits or valleys. For example, Japan's Akashi Kaiyu Bridge has a main span of 1991 meters. Its steel suspension bridge form has successfully achieved ultra-long distance spans, connecting Honshu Island and Awaji Island.

Product Application

Urban transportation: In cities, steel structure bridges can be used to build bridges across rivers and rivers to connect both sides of the city and relieve traffic pressure. For example, Shanghai's Nanpu Bridge adopts the form of a steel cable-stayed bridge and has become an important transportation hub in Shanghai, promoting exchanges and development between Pudong and Puxi. In addition, steel structure overpasses are widely used in urban roads to facilitate pedestrians to cross the street and ensure traffic safety. Their beautiful appearance and rapid construction complement each other with the urban environment.
