摘要
本文研究一种先进的结构安装法——旋转法在空间结构安装中运用的可行性.文中首先对推杆旋转安装法(推起法)和扳起旋转安装法(扳起法)两种方法的安装全过程进行内力变化的跟踪分析,从而指出旋转安装法的特点.同时,对若干工程实例进行讨论,最后对推杆起重机和施工铰提出设计建议.
<Abstrcat> The feasibility of an advanced rotation installation method applied to spatial structures is studied in the paper. Firstly, the whole installation process of handspike rotation installation method (impulse method) and pulling rotation installation method (pulling method) are analyzed by investigating the variety of internal force, and the characteristics are pointed out. Secondly, some examples in civil engineering are discussed. Finally, the suggestion in design of pole lift and construction gemel is presented.
