Lifting process of large-span net rack and truss combined roof
The invention discloses a lifting process for a large-span net rack and truss combined roof comprises the following steps that arranging lifting points; selecting a hydraulic lifter; selecting a steel strand; selecting a hydraulic system; selecting a hydraulic synchronous lifting system; designing a lifting platform; designing a temporary lifting point support frame; performing finite element analysis on the lifting platform and the roof; assembling net rack structures on the ground to form an integral lifting unit; erecting the lifting platform, and installing the hydraulic lifter; installing a guide frame used for being matched with the hydraulic lifter; arranging an auxiliary lifting appliance used for lifting; mounting the steel strands; connecting a hydraulic pipeline; connecting a control system and a power line; checking work before debugging; system debugging before lifting; carrying out graded loading and trial lifting; formal lifting for the first time; assembling the net rack which is lifted for the first time and the truss which is not lifted; lifting lifting point conversion; preparation before secondary lifting; lifting for the second time; and dismantling equipment and facilities. The lifting problem that in the roof lifting process, the height of the net rack is not consistent with that of a truss roof is solved.
一种大跨度网架与桁架组合屋盖的提升工艺，包括以下步骤，提升吊点布置；液压提升器选择；钢绞线选择；液压系统选择；液压同步提升系统选择；设计提升平台；临时吊点支撑架设计；对提升平台、屋盖进行有限元分析；将网架结构在地面上拼装成整体提升单元；架设提升平台，安装液压提升器；安装用于与液压提升器适配的导向架；布设用于提升的辅助吊具；安装钢绞线；液压管路的连接；连接控制系统、动力线；调试前的检查工作；提升前的系统调试；分级加载试提升；第一次正式提升；将已完成第一次提升的网架与尚未提升的桁架组装；提升吊点转换；第二次提升前准备；第二次提升；设备设施拆除，解决屋盖提升过程中网架与桁架屋盖高度不一致的提升难题。
