Abstract:

There are some challenges in the construction of high⁃rise overhead floor and refuge floor, suchas the inability to use standard layer aluminum alloy formwork, difficulty of ensuring safe operation, ultra⁃high support and non⁃turnover of horizontal formwork. Therefore, a series of innovative schemes are putforward, including the segmented construction of wall aluminum alloy formwork, the design of diagonalsupport aerial adjustable support, and the two⁃dimensional plan positioning aluminum alloy formwork ofdouble⁃channel steel joist of disk lock scaffold. The problem of using aluminum alloy formwork in theconstruction of overhead layer and refuge layer is solved by these schemes. Practice shows that thetechnology effectively ensures the construction quality and saves the construction cost.
