[0038] Bolt-ball grid structures are widely used due to their advantages of good spatial rigidity, light weight, economical materials, factory prefabrication, and beautiful appearance. In bolt-ball grid structures, the bearing performance of bolt-ball nodes plays a decisive role in the safety of the structure. However, in actual projects, bolt-ball nodes usually have the following problems: due to defects in construction technology and the prevalence of overload conditions, bolt-ball nodes often have varying degrees of damage, resulting in reduced bearing capacity and safety of bolt-ball nodes; due to long-term use, bolt-ball nodes are damaged, corroded or aged, resulting in the bearing capacity of bolt-ball nodes failing to meet design requirements; due to changes in building functions, increased design requirements or the addition of photovoltaic equipment on the roof, the original bolt-ball nodes cannot meet safety requirements. However, considering the economic cost, it is difficult to dismantle and rebuild. Therefore, it is usually necessary to reinforce or transform the existing grid structure to meet its bearing performance and normal use requirements.
