Tube truss

Pipe truss refers to a grid structure formed by connecting round rods at both ends. The truss makes the truss structure material economical, light in weight, and easy to form various shapes to adapt to different purposes, such as simply supported trusses, arches, frames, towers, etc.

These characteristics make the truss structure material economical and the structure weight is small. It is easy to form various shapes to suit different purposes, such as simply supported trusses, arches, frames and towers. Therefore, truss structures are widely used in many large-span stadium buildings today, such as conference centers, stadiums and other large buildings. Prefabricated building

In a truss structure, most of the bars are welded and connected at the nodes. Before welding, it is necessary to cut the web and chord according to the shape of the weld of each welding rod, which requires the intersection of the web and chord groove cutting at the end. Because the rods in the truss structure intersect with the rods in the form of intersecting lines, the cross-sectional shape of the two ends of the rods is relatively complicated, so in the actual cutting process, two methods of mechanical automatic cutting and manual cutting are generally used.
