Description

Technical Field

[0001] The present application relates to the technical field of building frames, and in particular to a belt truss and a construction method thereof. Background Art

[0002] A belt truss, a structural system supported by multiple, independently strength belts, is commonly used in projects such as stadiums and large exhibition halls. Its complex shape and structure necessitate the fabrication and prefabrication of steel trusses to ensure fast and efficient on-site assembly. Prior to installation, the prefabricated truss components are transported to the construction site and installed using heavy-duty lifting equipment.

[0003] To ensure that the components can be safely and smoothly positioned at the installation location, the ring-belt trusses are usually assembled into a whole first, and then hoisted to the predetermined location using a heavy-duty crane for installation. However, heavy-duty cranes are slow in moving the ring-belt trusses, and hoisting is difficult, which will affect the on-site construction efficiency. Summary of the Invention
