Description
Product introduction
Railway truss bridge refers to a bridge with truss as the main load-bearing component of the superstructure. The truss bridge is generally composed of the main bridge frame, the upper and lower horizontal and longitudinal connection systems, the bridge portal frame and the intermediate cross brace, and the bridge deck system.
Product application
Generally used for railway bridges or railway viaducts and overpasses 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
1. High bearing capacity
2. Fast construction speed
3. Energy saving and environmental protection
4. Beautiful building appearance
5. Good seismic performance
6. Quality assurance
Partial application
Great Wall has developed the container movement set independently, undertakes heavy steel structure fabricating business, promotes mechanical galvanization process for fastening parts.
The container movement set is not only supplied to domestic airplane manufacturing company, but also exported to country Haiti and so on meeting the demands of moving container in airport dock. The box girder, plate girder, guard rail such steel structures made by Great Wall are also well approved by clients. Great Wall mechanical galvanizing process made up the deficit of electroplating and hot galvanizing, showed extraordinary performance in field of environmental galvanization.
