摘要
神华黄骅港三期工程储煤筒仓群仓顶钢结构单个最大重量350 t,钢结构高空整体安装是难点和关键。针对钢结构重量大、吊装高度高、场地条件限制、施工工期、安全等方面,对储煤筒仓群超大钢结构高空安装技术进行方案比选,并对钢结构整体吊装时的受力采用Midas软件进行模拟分析,确定合理的吊点,保证整体吊装的稳定性。文章介绍了筒仓群超大钢结构的吊装工施工方法,其施工技术的成功应用可为类似工程提供参考。
The maximum weight of a steel roof structure of coal storage silos is 350 ton for the third-phase of Shenhua Huanghua Port. Altitude overall installation of the steel structures is difficult and critical. In the light of the large weight of the steel members, high lifting height, limitations on site, tight construction period, and safety, and other aspects of the instal- lation works, different installation technologies were compared and the stress on the steel structure when being integrally lifted was modeled and analyzed with MIDAS to determine the rational lifting points to ensure the overall stability of the steel struc- ture when being integrally lifted and installed. The paper introduces the technology and methods for lifting and installation of oversized steel structures for grouped storage silos, the successful application of which may provide a reference for similar pro- jects.
