在保证人身安全的情况下，考虑梁柱等吊装作业的通道和安装的方便性，以及脚手架搭设的简便。
Ensure safe operation of construction personnel, and pursue to the convenience of access of lifting activities (beam, column, etc.), installation and scaffold building in itself with the priority of safety.二、脚手架的搭设方式Building method of scaffolds：1、管廊、ECU钢结构管架吊装、安装搭设脚手架型式The scaffold type for lifting and installing steelwork on the Bench and ECUa.说明：钢结构地面成榀，在榀的两侧绑扎铝合金梯子，在榀的顶梁上面安设生命绳（14mm）挂搭安全带。
a. Note: the steel structure is assembled as one unit on the ground; ladders of aluminum alloy are fixed on the two sides of the assembling unit; and safety rope is set on the top for safety harness.b.梯子搭设和生命绳安设具体型式：The building type of ladder and safety rope is as follows:C.榀型钢构吊装就位后，使用4根封绳拉紧（若需要，加设倒链），进行找正和固定。
c. Straighten and fix the assembling unit with four wind ropes on completion of placement, if necessary, set hoisting block.d.生命绳扣（1.5m、2m长）单独制作，作为挂搭安全带使用（当安全带挂绳直接挂搭横梁不够长时使用）。
当横梁间距大于3m时，每根横梁上面仍使用生命绳（虚线）。
d. Fabricate safety rope and button with dimension of 1.5m×2m separately for safety harness, specifically, when the safety harness is not long enough to hang on the beam. When the space between vertical beams is more than three meters, it also will be used.

For the scaffold relatively low off the ground, build it from the ground directly or adopt the movable frame.b.离立柱近，在立柱周围的脚手架型式，以抱箍的方式往外延伸，具体型式如下：b. For the scaffold close to columns, build it by hooping the column and expanding outside. The building type is as follows:立柱抱箍脚手架搭设平面布置简图c.横梁下操作平台脚手架搭设，以吊蓝的方式进行搭设，搭设型式如下： For the platform scaffold under the beam, build it as suspended basket. The building type is as follows:4、焚烧炉混凝土框架顶（EL20700）以上钢结构吊装、安装搭设脚手架型式： Scaffold building type for lifting and installing steelwork on the concrete frame of incineratora.说明：钢结构地面成榀，在榀的两侧绑扎铝合金梯子，在榀的顶梁上面安设生命绳（14mm ）挂搭安全带。
a. Note: the steel structure is assembled as one unit on the ground; ladders of aluminum alloy are fixed on the two sides of the assembling unit; and safety rope is set on the top for safety harnessb.梯子搭设和生命绳安设具体型式：Ladder building type and safety rope setting type is as follows:横梁吊蓝操作平台脚手架搭设立面布置简图注：钢柱插入钢筋笼内的部分，搭设铝合金梯子时，应预留插入部分的长度。
Note: remain inserted length when building ladder of aluminum alloy for the part where steel column inserts rebar cagec.生命绳扣（1.5m、2m长）单独制作，作为挂搭安全带使用（当安全带挂绳直接挂搭横梁不够长时使用）。
当横梁间距大于3m时，每根横梁上面仍使用生命绳（虚线）。
C. Fabricate safety rope and button with dimension of 1.5m×2m separately for safety harness, specifically, when the safety harness is not long enough to hang on the beam. When the space between vertical beams is more than three meters, it also will be used. (Dot line)5、护拦搭设Guardrail building：所有操作平台均搭设：带防物件坠落踢脚板的护拦保护，其具体型式如下：For all the platforms, the guardrail with toe-board in case of falling is built as follows:三、临时斜梯的搭设型式：Building type of temporary inclined ladder钢结构的安装，由下往上，先梯子后平台。
如果没有工程上使用的正式梯子，需要上高到操作平台时，采取搭设防护斜梯。
其型式如下：The steel structure is installed from down to up with ladder first and then platform. If no formal ladder is furnished on the structure, temporary inclined ladder will be installed during the duration of working on the high platform. The type is as follows：四、脚手架搭设时，对成品的保护措施：Protective measures on products during the duration of building scaffolds为了保护混凝土柱梁、钢柱梁油漆，在梁柱上作为固定支点的脚手架绑扎位置，采用麻袋隔离的方式进行保护。
The position on the beam where scaffolds are tied will be protected by gunny cloth in order to protect the coat on the concrete column and steel column.五、钢结构施工工艺流程：Construction arrangement of steel structure1、LCI部分：LCIEL+20700以下斜梯（由下往上安装）→EL+11200平面→EL+12900平面→EL+15200平面→EL+17700平面（结合设备安装）→EL+20700平面（结合设备安装）→EL+20700平面以上钢结构Inclined ladEL+20700der (install from down to up) below –plane at EL+11200—plane at EL+12900—plane EL+15200—plane at EL+17700 (combined with equipment installation)-- plane at EL+20700 (combined with equipment installation)—steel structure above EL+20700EL+20700平面以上钢结构施工工艺流程：Steel structure construction arrangement above EL+20700地面组装成榀→吊装榀→安装连接梁→安装斜梯→从下往上（EL+25800、EL+30500、EL+34000、EL+36700）安装平台Assembling units on the ground—lifting assembling units--installation of connecting beam-- installation of inclined ladder--installation of platform from down to up.（EL+25800、EL+30500、EL+34000、EL+36700）2、ECU部分：ECUEL+23250以下斜梯（由下往上安装）→EL+9500平台及走道→EL+12500平面→EL+16500平面→EL+19500平面→EL+20300走道→EL+23250平面→EL+23250平面以上钢结构Inclined ladder under EL+23250(installation from down to up)—platform and walkway at EL+9500—plane at EL+12500—plane at EL+16500—plane at EL+19500—walkway at EL+20300—plane at EL+23250—steel structure above EL+23250EL+23250平面以上钢结构施工工艺流程：Construction arrangement of steel structure above EL+23250地面组装成榀→吊装榀→安装连接梁→安装斜梯→从下往上（EL+26350、EL+29400、EL+34000、EL+36700）安装平台Assembling units on the ground—lifting assembling units--installation of connecting beam-- installation of inclined ladder--installation of platform from down to up.（EL+26350、EL+29400、EL+34000、EL+36700）六、钢结构施工程序对脚手架型式的选用：Scaffold type selection of steelwork construction1、LCI部分：LCIa.斜梯安装：Installation of inclined ladderEL+9732平台，使用地面往上直接搭设（或使用现有的可移动式组合架）；On the platform at EL+9732, build it from the ground directly or use the movable frame beforeEL+12900平面以上，采用抱箍型式脚手架，即二、3、b条。
