Construction method of single-layer reticulated shell structure awning with cantilever structure
The invention discloses a construction method of a single-layer reticulated shell structure awning with a cantilever structure. The method comprises the following steps of firstly, constructing a plurality of layers of truss rings layer by layer to form a stable reticulated shell structure, integrally unloading, and then mounting a cantilever truss, so that the characteristics of an original structure are followed, and meanwhile, a large amount of investment of temporary supports can be reduced. In addition, compared with a traditional unloading manner with a sector as a unit, the unloading manner with an overall annular direction as an unloading unit has the advantages that stress conversion is more reasonable, deformation control is more scientific, the structural characteristics are fully considered, the stress conversion process is simpler, and higher safety is achieved. On the other hand, the temporary support can be repeatedly used, the utilization rate of the temporary support is increased, the construction measure cost is reduced, and the construction cost is saved. The problems that a large number of temporary supports need to be erected for a traditional single-layer cantilever reticulated shell structure, the repeated use rate of the temporary supports is increased through local unloading during construction and installation, and the deformation probability of the reticulated shell structure is increased are solved.
本发明公开了一种带悬挑结构的单层网壳结构罩棚的施工方法，先分层施工多层桁架圈以形成稳定的网壳结构后，整体卸载，再安装悬挑桁架，既遵循了原结构的特点，同时能减少临时支撑的大量投入。此外，按照整体环向为卸载单元的卸载方式，比传统按照扇形为单元的卸载方式，受力转换更合理，变形控制更科学，在充分考虑结构特点，受力转换过程更简单，具有较高的安全性。另外一方面，可多次重复使用临时支撑，提高了临时支撑利用率，降低了施工措施费，节约了施工成本。本发明解决了传统的单层悬挑网壳结构需要搭设大量临时支撑，施工安装时采用局部卸载提高临时支撑重复倒用率，导致网壳结构变形概率增高的问题。
