一、原理 互升降外墙脚手架的工作原理主要是利用普通手拉葫芦(也可用电动葫芦)提升每榀独立搭设的脚手架,每榀脚手架设2～4个起吊点(视脚手架外形尺寸而定),而手动葫芦是吊挂在两相邻的已固定在建筑物上的脚手架上或预埋于建筑物的吊环上,脚手架提升到位后,则固定在建筑物的预埋吊环上,且在各相应部位均设有水平拉、顶杆,固定完成后再提升相邻的脚手架,整层脚手架提升完成 First, the principle of the principle of mutual lift external scaffolding is mainly the use of ordinary chain hoists (also available electric hoist) to enhance the erection of each scaffold independently erected, each scaffolding set 2 to 4 lifting points (depending on the size of the scaffold) The manual hoist is hung on two adjacent scaffolds fixed on the building or embedded in the building’s rings. After the scaffold is lifted into place, it is fixed on the built-in rings of the building, and each Corresponding parts are equipped with horizontal pull, top bar, after the completion of the completion of the promotion of the adjacent scaffold, the entire scaffolding upgrade is completed
