Abstract：
Beijing Yanqi Lake Tower is a tower-shaped archaized building, having nine ground floors on an octagonal plan. The building has a metal spire and terraced overhanging eaves on each floor. It has high requirements for external scaffold, so various measures were adopted, such as multi-row scaffold, gradual shrinkage, forward-backward column pressing and internal cantilever, double poles and steel cable unloading, etc., to share between structural construction and decoration. Construction schedule was shortened and construction requirements were satisfied, realizing favorable economic and social benefit.
