1.概述scope

本工程钢构件单体重量最大不超过10t,单体高度最高20米,综合以上条件,钢结构的吊装主要由一台100t吊车(CCH1000)来完成。

此吊装方案仅限辐射段钢结构及小件钢结构单体,对于以后的对流段钢结构等风险系数较高的大件钢结构吊装,将做补充方案。

2.吊装准备liftingpreparations

2.1.由吊装技术负责人向现场施工人员交底

材料放置图

主框架结构按照预制成品沿N4、N3轴的轴线由紧靠原裂解炉F-1110的一侧向东的顺序在地面分两榀组对(N4轴-A、B轴；N4轴-B、D轴；N4轴-D、F轴；N4轴-F轴、H轴；N3轴-A、B轴；A轴-N3、N4轴；N3轴-B、D轴；N3轴-D、F轴；N3轴-F、H轴；H轴-N4,N3组对成榀)，每跨，依次安装；最后在按以上方法组对N2、N1轴;各组拼片负荷率及重量见表3-2。
