水泥工厂预均化库屋盖柱面网壳悬挑安装方法

On cantilever erection method at cylindrical lattice shell on roof of pre-homogenization store in cement plant

通过对跨度49 m预均化库双层柱面网壳进行研究,采用有限元法对网壳小拼单元悬挑安装方法进行了施工全过程数值模拟,考察了悬挑安装过程中网壳结构杆件内力的变化情况,对柱面网壳结构悬挑安装的实际实施提出建议。

The paper researches the double-layer cylindrical lattice shell on the pre-homogenization store with the span of 49 m, adopts the finite element method to undertake the whole-process numeric simulation of the small assembling unit cantilever erection method, observes the changes at the internal forces of rod of the lattice shell structure in the cantilever erection process, and points out some suggestions for the implementation of the cantilever erection of the cylindrical lattice shell.
