局部单双层网壳结构的两种新型施工方法

Two New Construction Methods for Reticulated Shell with Partial Single Layer

局部单双层网壳结构施工比较成熟的有滑移支架安装法和双层骨架 单层网壳分别提升法。本文介绍这 2种新方法的施工过程及施工力学验算要点 ,并通过主要施工指标比较 ,表明它们的效率比常规施工方法高。

Relatively perfect construction methods of reticulated shell with partial single layer are the approach of assembling of single\|layer lattice shell on slide trestle table, and the approach of separately hoisting of double\|layer framework & single\|layer lattice shell. The paper introduces the construction process and the efficiency of each method. The mechanical analysis of construction process is also discussed. Practices show the efficiency of each approach is higher than conventional construction methods.
