Construction method of I-shaped steel scaffold for large-span cantilever structure construction of high-rise cluster project
The invention discloses a construction method of an I-shaped steel scaffold for construction of a large-span cantilever structure of a high-rise cluster project. The construction method comprises the following steps that (1) a plurality of horizontal cantilever beams are arranged; 2) arranging a plurality of groups of vertical rod assemblies; 3) arranging a first cross rod and a second cross rod; (4) arranging a shear brace assembly; (5) wall connecting construction; (6) unloading construction; (7) scaffold boards and foot blocking boards are arranged; (8) protective fences are arranged; and (9) after building body construction is completed, the cantilever beam outer scaffold is dismantled. The overhanging structure scaffold is adopted to replace a high-rise building to be erected and constructed from the ground, and the defects that an all-round scaffold is large in material consumption, long in mounting and dismounting time, long in consumed time, high in cost, difficult to mount and dismount, high in danger, large in material investment and the like are overcome. Compared with a cable-stayed rope pre-embedded ring of a cantilever frame in a traditional method, the cantilever frame saves labor and can be repeatedly used, the length of the pull rod can be adjusted at any time so as to ensure the stability of the frame body, and the I-shaped steel can be repeatedly used.
本发明公开了一种高层集群项目大跨度悬挑结构施工工字钢脚手架的工法，包括如下步骤：1)设置多个水平悬挑梁；2)设置多组立杆组件；3)设置第一横杆和第二横杆；4)设置剪力撑组件；5)连墙施工；6)卸荷施工；7)设置脚手板和挡脚板；8)设置防护栏；9)楼体施工完成后，拆除悬挑梁外脚手架。通过采用悬挑结构脚手架代替了高层建筑物从地面搭设施工，解决了满堂脚手架耗材大，安拆时间长、耗时长、成本高、安拆困难、危险性高、材料投入较大等缺陷。与传统做法的悬挑架的斜拉绳“预埋环”对比，即省工又可多次周转利用，可随时调节拉杆长短以确保架体的稳定性，工字钢可重复利用。
