一、概述仪征化纤厂涤纶一厂抽丝车间的Ⅰ、Ⅱ、Ⅲ、Ⅳ区为预制混凝土框架结构,共有546根预制混凝土柱。其中Ⅰ、Ⅱ区有234根,柱高为h≈19米,Ⅲ、Ⅳ区有312根,柱高h≈12.5米。柱子吊装与梁板吊装同时进行。垂直度校正,用二台J_6级经纬仪,由纵、横二个方向进行。并对已校正,临时固定的柱子,在吊装、焊接与其联结的梁板时,继续监测、校正,直至焊接完毕。吊装结束后,用J_6级经纬仪对柱子的纵
I. General description I, II, III, and IV areas of the spinning shop of the Yizheng Chemical Fibre Plant Polyester 1 Plant are precast concrete frame structures with a total of 546 precast concrete columns. Among them, there are 234 in the I and II areas, and the column height is 19 meters in height, 312 in the area III and IV, and the column height is 12.5 meters in height. Column lifting and beam lifting are performed at the same time. Verticality correction, using two J_6 theodolites, vertical and horizontal directions. As for the pillars that have been corrected and temporarily fixed, they shall continue to be monitored and corrected during lifting and welding and the beams and plates that they are connected to until the welding is completed. After the lifting is completed, use the J_6 theodolite to align the column
