Inhaul cable auxiliary supporting system for integrally lifting curved surface reticulated shell structure
The invention provides an inhaul cable auxiliary supporting system for overall lifting of a curved-surface reticulated shell structure, and relates to the technical field of building steel structures, the inhaul cable auxiliary supporting system is used for lifting a prefabricated curved-surface reticulated shell rod piece and comprises a flexible inhaul cable and an adjustable supporting rod, and through cooperation of the flexible inhaul cable and the adjustable supporting rod, the rigidity of the curved-surface reticulated shell rod piece is greatly improved; prestress is applied to the flexible inhaul cables, so that the curved-surface reticulated shell rod pieces generate reverse deflection, final deformation of the curved-surface reticulated shell rod pieces under the load effect in the lifting process is reduced, the adjustable supporting rods provide elastic supporting for the curved-surface reticulated shell rod pieces, and the stress performance of the curved-surface reticulated shell rod pieces can be effectively improved. According to the method, the curved surface reticulated shell rod pieces of different specifications can be appropriately lifted, appropriate control information is given mainly through a lifting deformation algorithm, the adjustable supporting rods push the flexible inhaul cables, deformation of the curved surface reticulated shell rod pieces is within a controllable and reasonable range, then the safety of lifting construction is effectively guaranteed, and the popularization value is high.
本发明提供了一种曲面网壳结构整体提升的拉索辅助支撑系统，涉及建筑钢结构技术领域，其用于提升预制的曲面网壳杆件，包括柔性拉索和可调节支撑杆，本发明通过柔性拉索和可调节支撑杆的配合，大大提高曲面网壳杆件的刚度；柔性拉索中施加预应力，使曲面网壳杆件产生反挠度，从而减少提升过程曲面网壳杆件在荷载作用下的最终变形，可调节支撑杆对曲面网壳杆件提供弹性支撑，能够有效改善曲面网壳杆件的受力性能；本发明能够针对不同规格的曲面网壳杆件进行相适宜的提升，主要通过提升形变算法给出相适宜的控制信息，使得可调节支撑杆推动柔性拉索，使得曲面网壳杆件形变处于可控合理范围内，进而有效保障提升施工的安全性，推广价值大。
