Net frame installation is one of the most critical stages in the whole project, especially in the construction of high altitude or large span venues, where risks and challenges exist. Installation key points of attention: Measuring and placing lines must be accurate: errors can cause the whole structure to be docked out of place.  Clear component numbering and safe transport: large components often need to be transported in sections, and on-site assembly to the right number is key.  Welded nodes should not have concentrated stress: buffer design should be adopted to avoid deformation or cracks caused by thermal stress.  Work-at-height safety: wear safety belts and use standard scaffolding and lifting equipment.

 The steel structure bolted ball connection realises the welding-free assembly of the mesh frame nodes through the precision cooperation of the built-in cone head, socket and high-strength bolts, which significantly improves the construction efficiency and stability of the structure, and is especially suitable for large-span space structures. The core principle of the bolt ball node is based on the mechanical transmission path: the tension is transmitted through the steel pipe → cone head → high-strength bolt → steel ball, and the pressure is dispersed to the ball through the sleeve. Its design needs to meet the limitations of ball diameter ≤ 300mm, bolt specification ≤ M64 and other parameters to ensure the node bearing capacity and seismic performance. The co-ordination between the built-in cone head and the sleeve can avoid the weld quality defects caused by the welding of the traditional external cone head, and at the same time reduce the on-site installation errors.
