In the field of architecture,high steel bridge more and more embodies its value. Because of its low cost, good structural performance, fast construction speed, good texture and strength, it is gradually recognized by people. high steel bridge is developing at a rapid speed, and to some extent, it replaces the previous reinforced concrete structure bridge. However, due to the wide application of high steel bridge in bridge engineering, it is bound to have such defects and shortcomings in construction technology, construction technology and construction quality. Therefore, the control of key points in the construction of high steel bridge is the key to ensure the quality level of high steel bridge, and it is also a huge driving force for the development of high steel bridge in China's bridge industry.
Structural characteristics, advantages and disadvantages of high steel bridge
(1) High steel bridge is a type of bridge, which means that the main bearing part of the superstructure of a bridge is made of steel. high steel bridge, like bridges, are all roads in the air across rivers, lakes and marine obstacles, among which the long-span bridges are mostly prestressed steel concrete bridges and high steel bridge. The structure of high steel bridge is composed of main bridge along its longitudinal direction. The span between piers is called span, the main bridge spans the main navigation hole section is called main span, and the span is side span. The main materials used for high steel bridge are steel plate, section steel and high strength. Low alloy steel is mostly used for steel plate, and cast steel and high-quality carbon are used for parts. The main types of steel beam are ribbed plate beam, box beam, truss beam and composite beam.
(2) Advantages and disadvantages of high steel bridge. high steel bridge is an ideal material for long-span bridges because of its high-strength material, good homogeneity and easy processing. Secondly, it is easy to set up. This point can be compared in the construction of steel beams. The main disadvantage of high steel bridge is that it is corroded under the action of atmosphere, easy to rust, high maintenance cost, and more expensive.
