金茂大厦工程从54层起往上是一个像烟囱般的中庭结构，在现代节奏的施工条件下，建设它必然会形成多种的立体交叉作业，在高处栏杆周边，几十支焊枪同时进行焊接、切割作工时，整个中座火花飞溅，就像天女散花一样美丽壮观，但是就是这漫大飞舞的高温融珠，一不小心就会落到下? The Jinmao Tower project from the 54th floor upwards is a chimney-like atrium structure. Under the modern rhythm of construction conditions, it will inevitably form a variety of three-dimensional crossover operations. At the height of the railing, dozens of torches are in the vicinity. During the welding and cutting work, sparks splashed throughout the middle seat, just as beautiful and spectacular as the female scatters, but it was the high-temperature melting ball that fluttered around, but accidentally it would fall.
