5、e范围 This instruction is applicable to the steelwork erection of 4 set fuel (gas) boilers in Nanhai peotrochemical steam the weight of the assembly parts shall be controlled within the lifting capacity of thr crane.After assembling on the specified field of boiler 0m ground, use the CC-1000 crawler c
6、rane to hoist the assembly parts into position. The scaffold used for frame erection shall apply Scaffold Management Procedure. While using portable ladders, operators shall obey Portable Ladders Management Procedure. Execute Lifting Transportation Management Procedure in the transportation of lifti
7、ng equipment.立柱和其间连梁安装是钢架安装过程中最危险的作业之一，根据我们以往的施工经验，采用在立柱顶端拴挂软爬梯进行高空作业的方案，同时采用速差自控器作为防护措施，以确保高空作业的安全性。 （软爬梯的使用详见附件软爬梯实行计划 ） 。一层立柱、横梁用 50A履带吊分区域进行吊装，50A 履带吊沿 2、3 列柱之间锅炉中心线前后方向行车，从炉前向炉后依次吊装 E 列柱、D 列柱、C 列柱、B 列柱、A 列柱及其相连的横梁斜撑。一层吊装完毕后，用 CC-1000 履带吊吊装 2、3、4 层钢架。立柱吊装时，每一个立柱用两个 4.75t 美式弓形卸扣直接与钢架螺栓孔连接起吊，锅炉钢架横
8、梁直接用钢丝绳拴紧,吊装。锅炉钢架根据现场施工需要，进行适当的组合，组合件重量控制在 10t 以内，组合件在锅炉零米组合场地组合完成后，由 CC-1000 履带吊吊装就位。锅炉钢架安装用的脚手架应符合脚手架管理程序 ，便携式梯子使用时应符合便携式梯子管理程序 ，设备的起重运输执行起重运输安全管理程序 。b. When the column is installed, the end surface of the column must be tightened. The maximum allowable clearance on the butt joint contact surface
9、of the column is no more than 0.5mm. When erection, contact the butt joint surfaces first, then join them by high strength bolt.钢柱安装时，柱的端面必须顶紧，钢柱对接接触面允许的局部间隙最大不超过 0.5mm。安装时应让对接端面先接触，然后再用高强螺栓连接。c. When the first layer column is put into position, the column baseplate centerline and foundation centerline must be aligned, Adjust the elevation of column by bolt jack. The bolt welded on the baseplate shall be used to assist the stability of the column. Then tighten the nut and standby nut of
