大跨度悬吊结构临时支撑体系的设计与应用

Erection technology of high-altitude cantilevered steel beam platform

大跨度悬吊结构临时支撑体系往往受空间影响高宽比大,承载力和抗倾覆性较难满足难要求。为寻求其可靠的临时支撑体系,以济南高新文化中心工程为例,从基础类型和架体构造两个方面考虑,结合微型钢管桩、高支模等传统工艺,设计了一种稳定有效的大跨度悬吊结构临时支撑体系,并系统的介绍了其施工要点和监测要点,其结果表明了该临时支撑体系是安全可靠的。

The construction support system of long-span suspension structures is often affected by space,and the height-to-width ratio is large.In order to find a reliable construction supporting system,taking the Jinan high-tech Cultural Center project as an example,considering the foundation type and frame structure,combining with the traditional techniques such as mini-steel pipe pile and high formwork,a stable and effective temporary support system for long-span suspension structure is designed,and its construction and monitoring points are systematically introduced.The results show that the temporary support system is safe and reliable.
