Project Update: Swimming Hall Roof Space Frame Completed

A 50m-span bolted-ball space frame assembled on the ground and lifted whole — high-altitude work cut by about 70%.

This swimming hall roof uses a 50m-span square-pyramid space frame with bolted-ball nodes, covering the standard pool area.

Instead of traditional piece-by-piece erection at height, we assembled about 85% of the frame on the ground and lifted it into place with hydraulic jacks at 8 synchronized points. Work at height dropped by roughly 70%, the schedule saved 12 days, and quality checks were done on the ground — far more thoroughly.

This project shows the classic strengths of bolted-ball frames: no site welding, high erection accuracy and minimal maintenance. The same solution suits gymnasiums, exhibition halls and other wide-span public spaces.
