重工业的老厂房在拆旧改造屋面板工程,过去一直沿用塔吊地而作业施工方法。但在施工前在塔吊行走路线上必须拆除设备,填平地基,铺平路面,费用高,工期长。为了改变这种落后施工方法,我们反复进行多方案比较和理论验算。因屋面板老 The old factory buildings of the heavy industry are demolition and renovation of the roof slabs. In the past, the tower cranes had been used along with the construction methods. However, before the construction, the equipment must be dismantled on the walking route of the tower crane, fill the foundation, and paved the road surface. The cost is high and the construction period is long. In order to change this backward construction method, we repeatedly performed multiple program comparisons and theoretical calculations. Due to the roof panel
