AI Technical Summary

Technical Problem

Existing methods for assembling space frames require the erection of temporary supports and lifting platforms, resulting in high material consumption, long equipment rental periods, high construction costs, and safety risks.

Method used

A temporary lifting system using a space frame ball node is adopted, including welded balls, steel sleeves, stiffening plates and base plates. Combined with a hydraulic lifter, steel strands and an electrical synchronous control system, it achieves vertical lifting and synchronous attitude control. Power is provided by a hydraulic pump station, and a lifting platform is erected using permanent columns. A modular hydraulic pump station and computer control system are used for synchronous lifting.

Benefits of technology

This enabled flexible use and high utilization of the equipment, reduced the impact of temporary supports, improved construction safety and efficiency, reduced construction costs, and avoided permanent structural damage.

Abstract

This invention relates to a temporary lifting device, system, and lifting method for a spherical node in a space frame, and pertains to the field of construction technology for the overall lifting of welded spherical space frames. It includes a welded sphere, steel sleeves, stiffening plates, and a base plate. Steel sleeves are connected to the top and bottom of the welded sphere, and the bottom steel sleeve is connected to the base plate. A stiffening plate is welded between the base plate and the welded sphere. This invention solves the problems of existing technologies, such as the inability to reuse temporary scaffolding, low utilization rate, long construction period, long rental period for large lifting equipment, high cost, and high safety risks associated with high-altitude operations.
