AI Technical Summary
Large tower cranes are not suitable for the installation of cantilevered space frame structures. The complex shape of cantilevered space frame structures interferes with the operating space of large tower cranes, making it difficult to align and splice the steel frames. In addition, welding operations require high-altitude work and have high construction costs.
The steel structure frame is installed using an installation device, including BIM modeling, the use of steel pipes and node connection devices, and the stable movement and splicing of the steel frame is achieved through a lifting mechanism and an opening and closing mechanism. The adjustable rotating rods and grouting nails of the node connection device are used for fixing, reducing welding work.
The use of large tower cranes was avoided, saving costs, reducing the risk of safety accidents, improving work efficiency, achieving stable alignment and splicing between steel frames, and reducing the quality requirements of personnel and materials for welding processes.
