The invention discloses a large vestibule spanning type installation method. When a large-span truss section is hoisted, the rear position of the middle point of the large-span truss section is divided into a front truss and a rear truss, the rear truss can be erected on the front truss through a tongue-and-groove support, each truss is divided into a left truss and a right truss, a purline is installed before each truss is hoisted, a front fixing support is arranged at the front end of a special section, a temporary support is arranged at the position, corresponding to the midpoint of the large-span truss section, of the middle of the special section; a rear fixing support is arranged at the rear end of the special section; a crane lifts two front trusses on the front fixing support and the temporary support in front of the special section; two front trusses are fixedly connected through a purline; the crane hangs two rear trusses on the rear fixing support and the two front trusses at the rear of the special section; the front trusses and the rear trusses are welded at rabbets, the two rear trusses are fixedly connected through the purline, stress rods on the large-span truss section are welded and fixed, and finally, the temporary support is dismantled. According to the invention, the crane does not occupy a special section and is stable to mount.

    本发明公开了一种大型通廊跨越式安装方法,吊装大跨度桁架段时,大跨度桁架段中点靠后位置分开为前后两部桁架,后部桁架能通过企口支撑搭放在前部桁架上,每部桁架分开为左右两片桁架,每片桁架吊装前都先安装檩条,在特殊地段的前端设置前固定支架、中间对应大跨度桁架段中点位置处设置临时支架、后端设置后固定支架,吊机在特殊地段前方吊放前部两片桁架在前固定支架和临时支架上,通过檩条将前部两片桁架固连,吊机在特殊地段后方吊放后部两片桁架在后固定支架和前部两片桁架上,将前后两部桁架在企口焊接、通过檩条将后部两片桁架固连、将大跨度桁架段上的受力杆件焊接固定,最后拆除临时支架。本发明吊机不占用特殊地段,安装稳固。
