Description

Technical Field

[0001] This utility model belongs to the technical field of large-span trusses, specifically relating to a modular prefabricated rapid erection structure for large-span trusses in cold regions. Background Technology

[0002] Truss: A structure consisting of members connected to each other at both ends by hinges. Trusses are planar or spatial structures composed of straight members and generally have triangular units. Truss members mainly bear axial tension or compression, thus making full use of the strength of the material. When the span is large, it can save material, reduce self-weight and increase stiffness compared to solid beams.

[0003] When erecting large-span trusses, rapid erection structures are used. However, existing rapid erection structures for large-span trusses are prone to slippage when erecting them in cold weather, especially after snowfall, as ice forms on the erection structure. This results in poor accuracy during adjustments. Therefore, the development of modular prefabricated rapid erection structures for large-span trusses in cold regions has significant practical importance and market demand. Utility Model Content
