Product application
Generally used for road-rail bridges with small spans.
Product Structure
In a truss, the chord is the members that make up the periphery of the truss, including the upper chord and the lower chord. The members that connect the upper and lower chords are called web members. According to the different directions of the web members, they are divided into diagonal rods and vertical rods.
The plane where the chords and webs are located is called the main girder plane. The bridge height of the large-span bridge changes along the span direction to form a curved string truss; the medium and small spans use a constant truss height, which is the so-called flat string truss or straight string truss. The truss structure can be formed into a beam or arch bridge, and can also be used as the main beam (or stiffening beam) in a cable support system bridge. The vast majority of truss bridges are constructed of steel. The truss bridge is a hollow structure, so it has a good adaptability to the double deck.
Product advantages
Steel truss bridge combines the advantages of steel and truss structure:
1. Light structure and large spanning ability
2. Easy to repair and replace
3. The steel truss beam has many members and nodes, the structure is more complicated, and the stability is stronger
4.Strong resistance to pressure and good integrity
5. Wide range of use
