Synchronous control technology resolves contradictions in traditional steel structures

With continuous technological advancements, traditional steel structure construction techniques can no longer meet construction requirements. Therefore, the market is constantly adjusting construction techniques to address the contradictions between technology and requirements. This has driven the further development and application of the integrated steel structure lifting technology, which offers better economic and social benefits.

According to online sources, the ground-assembly integrated lifting method for steel structure projects involves assembling the steel connecting corridor section (made of color-coated steel panels) on a floor assembly platform, then using lifting equipment to raise it to the design elevation and connect it with the corbels on the surrounding structure. This method significantly reduces high-altitude work and has advantages such as shorter construction time, higher efficiency, and lower cost.

The integrated steel structure lifting construction technology, with synchronous control as its core, mainly includes "steel strand load-bearing, computer control, and cluster operation of hydraulic jacks." This method consists of a cluster hydraulic jack system, a pump station system, a steel strand load-bearing system, a sensor detection system, and a computer control system. The integrated lifting technology offers advantages in saving construction costs and shortening the construction period.

The control system employs computer control, transmitting control commands via CAN bus technology. It automatically performs multiple functions including synchronous movement, load balancing, attitude correction, stress control, operation locking, process display, and fault alarms. It is a modern, advanced device integrating mechanics, electronics, hydraulics, sensors, and computer control.

Successful Application Example of Steel Structure Lifting Synchronous Control Technology: For aesthetic purposes, an aerial walkway was designed between Towers A and B of the Shouke Building. This steel structure connects the two towers, with a base elevation of 75 meters, a span of 42 meters, and a self-weight of approximately 200 tons. If traditional methods were used for aerial assembly, it would require erecting full-span scaffolding on the rooftop from an elevation of 22 meters to 75 meters, which is technically and practically impossible. After extensive expert evaluation, it was decided to adopt a ground-based assembly and overall lifting method, employing a complete set of steel structure lifting technology with synchronous control as its core.
