Construction Method for Large-Span Hyperbolic Hybrid-Node Space Frame Structure

In recent years, curved and irregular spatial steel structures have been increasingly used in major architectural projects around the world, thanks to their unique forms, special force-bearing systems, strong spatial expressiveness, and adaptability to various spans and support conditions.

As design and construction technologies continue to advance, the shapes and spans of space frames are pushing the boundaries of visual impact. This construction method divides the large-span hyperbolic openwork triangular pyramid hybrid-node space frame into two main parts: the edge trusses and the internal grid. This greatly reduces the amount of high-altitude assembly work. The edge trusses are assembled on the ground, undergo ground-level inspection, and are lifted as complete units into place, ensuring installation quality while minimizing the risks of working at height and reducing the need for scaffolding.

Taking into account the support conditions and shape characteristics of the space frame, the assembly units and sequence are logically divided to eliminate most installation deviations within each assembly unit. By fully utilizing the characteristics of structural expansion joints, the units at the joints are assembled last to eliminate any remaining installation errors, ensuring smooth final closure. The internal space frame is preassembled into small units in advance to facilitate quicker on-site assembly and accelerate the overall construction progress.

Through comprehensive quality control of the entire construction process, rework is minimized, one-time installation success is achieved, and acceptance is passed in one go—greatly improving construction efficiency. Tailored safety and site management measures are proposed based on the unique features of space frame construction to ensure safe and orderly execution.
