[0002] With the development of society, the shortage of land resources has become increasingly prominent, and more and more high-rise buildings are being constructed. The scaffold, which is indispensable in the construction process of high-rise buildings, is also crucial. For high-rise buildings, sectional cantilevered protective scaffolds or integral lifting protective scaffolds are mostly used. When the traditional cantilevered scaffold is erected, positioning steel bars need to be welded on the cantilevered I-beam to fix the vertical poles of the scaffold to prevent sliding.
