AI Technical Summary

Technical Problem

During the construction of steel structure cooling towers, the installation of purlins and the enclosure structure require a large number of components, resulting in a large workload and a long construction period.

Method used

The main structure is constructed by splicing rhomboid structural units to form a spatial curved surface structure. It combines flexible membrane units and cable structures. The flexible membrane units are supported by the cable structures, reducing the number of components. The flexible membrane units are directly tensioned by bolts, avoiding the need for self-tapping screw connections.

Benefits of technology

It significantly reduced the amount of construction work, shortened the project period, improved the stability and wind suction resistance of the structure, simplified the stress relationship, and facilitated construction design and maintenance.
