Hoisting method of large-span curved truss
The invention relates to a hoisting method of a large-span curved truss, and belongs to the technical field of large-span steel structure construction. The method comprises the steps of assembling the curved truss, preparing hoisting equipment, demolding, turning over, hoisting, rotating, placing in place and mounting a support. According to the method, the auxiliary turning-over device is designed and used, the truss has a supporting point making contact with the ground all the time in the hoisting turning-over process through use of the auxiliary turning-over device, the stability of the truss in the hoisting process is improved, and therefore the whole hoisting operation can be completed only through two cranes, the difficulty of cooperation of multiple cranes is reduced, the safety of the construction process is improved, then the hoisting difficulty is reduced, the hoisting efficiency is improved, and the construction period is shortened.
本发明为一种大跨度曲线型桁架的吊装方法，属于大跨度钢结构施工技术领域。本发明方法步骤为曲线型桁架的组装、吊装设备的准备、脱模、翻身、起吊、转体、就位和支座安装。本发明方法设计使用了辅助翻身装置，辅助翻身装置的使用使得桁架在吊装的翻身过程中始终有一个与地面接触的支承点，提高了吊装过程中桁架的稳定性，也正因如此，才使得本发明方法只需两台吊车即可完成整个吊装作业，降低了多台吊车协同的难度，提高了施工过程的安全性，进而使得吊装难度降低，提高了吊装效率，节省了工期。
