某高层大跨度联体钢构吊装及变形控制施工方法

Installation Technology and Deformation Control of a High-level Large-span Steel Hoisting Structure

通过实例分析,介绍在受地域限制及地面承载限制、大型起重机无法到位、而中小型汽车吊又无法满足起升高度及安装重量等要求的特殊情况下,采用桅杆吊装法成功解决施工难题,同时降低工程造价.结果表明,此方法简单、适用,对类似工程的安装具有很好的参考意义.

Through a case analysis,it was described that as the geographical limitations and ground bearing restrictions existed and large cranes could not be put in place,but medium-sized car used for hanging up could not meet height and weight requirements the mast hoisting technology was used to solve problems successfully and the project cost was reduced.Results indicated that this technology was very simple and applicable,which may be a reference for similar projects.
