摘要
当前大跨钢桁架结构的安装仍主要采用传统的方法,应用时存在一定的局限性。以厦门新会展中心—会议中心项目为载体,提出大跨钢桁架结构的负角度转体提升安装方法,并对其关键控制工序进行详细论述。而后,基于结构有限元分析软件对转体提升施工全过程钢桁架结构的变形及受力进行计算。最后,基于现场实施过程对该安装方法的可靠性进行分析。分析结果表明:自适应转体提升法安装技术在安全、质量、临时措施量及进度控制等方面均具有一定优势,在类似的大跨钢桁架结构的安装具有推广价值。
The installation of long-span steel truss structure mainly using traditional methods,there are some certain limitations in engineering applications.Taking the Xiamen New Convention and Exhibition Center-Conference Center project as background,a negative angle swivel lifting installation method for long-span steel truss structure was proposed,and the key control processes were discussed in detail.Then the deformation and stress of the steel truss structure during the entire process of self-adaption swivel lifting construction were calculated by using finite element analysis software.Finally,the feasibility of this installation method was analyzed based on the on-site implementation process.The analysis results indicate that the self-adaption swivel lifting construction technology has certain advantages in safety,quality,temporary measures,and progress control,and show its promotion value in the installation of long-span steel truss structure.
