Background technique

In recent years, rectangular trusses have been increasingly used in construction, bridges and mechanical engineering. Rectangular trusses are composed of multiple rods and connecting nodes to form a stable rectangular grid structure. As the span requirements for rectangular trusses are getting larger and larger, their volume and weight are large, and overall transportation is very difficult. Therefore, usually after the rods and connecting nodes are processed in the factory, they are transported to the site and assembled into multiple truss units on the assembly frame. The truss units are then hoisted separately and spliced at high altitude.

At present, the assembly frame used for the rectangular truss is usually customized according to the structural dimensions of the truss unit. When the structural dimensions of the truss unit change, the assembly frame needs to be remade, which is not only time-consuming and labor-intensive, but also causes a large amount of material waste.
