地铁科学馆站路灯拆迁施工组织设计方案2锅炉本体钢架安装 Boiler steel structure erection
钢架内侧柱为主要承重钢柱，外侧副柱则通过梁、水平支撑与内侧柱相连，以增加钢架的整体稳定性。钢结构从前至后共有6排。锅炉钢架的连接，采用高强螺栓和焊接相结合的方式，顶板和主梁与次梁之间，柱和梁之间，垂直支撑、水平支撑之间采用扭剪型高强螺栓连接，其余构件间采用焊接连接。 Internal pillars of the structure are designed for bearing, while the external pillars are designed to reinforce the entire stability of structure by connecting with girders, lateral supporting and internal pillars. There are 6 rows. Bolt and welding are employed in the connection of structure.

Q／GDW 1868-2012 风电场接入系统设计内容深度规定.pdf3顶板梁吊装方案 Roof girder hoisting plans
锅炉钢结构第八段立柱、横梁、拉条安装完毕后，根据大板梁吊装需要，部分杆件预留，经检验合格，才能进行板梁吊装。
锅炉顶板梁的吊装机械为FZQ2010/80t圆筒吊和CC1400/CC2500履带吊。FZQ2010/80t圆筒吊布置在#1、#2炉的两侧,每台炉有一台磨机缓装，CC2500/CC1400履带吊在2台炉中间机动布置，看情况缓装一台磨煤机，使CC2500/CC1400满足顶板梁吊装工况。。 FZQ2010/80t cylindrical crane and CC1400/CC2500 crawler crane are employed to hoist boiler roof plate girder. FZQ2010/80t cylindrical crane should be arranged in both sides of boiler #1and#2, each boiler should be arranged with one mill after later. , while CC1400 or CC2500 crawler crane should be arranged between the tow boilers ,one mill should be erected later if necessary so that CC2500/CC1400 can meet the requirement of roof plate girder hoisting.
