The materials should be in accordance with the requirements to steel Q-235A by GB7008-79. b) 扣件选用型号为KT-33-8的可锻铸铁，扣件紧固用螺栓选用材质为Q-235A钢制作。Use the mollealle iron KT-33-8 to be the fasteners. Bolts to fix fasteners should be fabricated by steel Q-235A.c) 跳板选用材质为Q-235A钢制作，厚度不低于2mm。Use steel Q-235A to fabricate the planks, with thickness 2mm or more.4.2 脚手架搭设型式及设备平台安装顺序Scaffolding Erection Type and Installation Sequence of Platform of Equipments1） 采用双排扣件式井字脚手架。The scaffolding shall be double-row “#”-shape scaffolding with fasteners.2） 设备平台、附塔管线安装顺序：脚手架搭设到每层平台处后（离设备平台约1.2米），安装设备平台及与下层设备连接直梯；设备平台安装完毕后，继续往上搭设脚手架，安装设备平台和爬梯。（见附图1）。 Installation sequence of equipment platform & pipelines: After the scaffolding is erected on each floor of platform (about 1.2m away from the equipment platform), install the ladders connecting the platform with the equipment at the lower level. After the completion of equipment platform installation, continue to erect scaffolding above and install the equipment platforms & ladder. (See the details in the attachment figure 1)3） 搭设脚手架时避开设备爬梯位置。Avoid the positions of equipment ladders when erecting scaffolding.4.3 双排扣件式井字脚手架搭设： Erection of Double Row “#”-Shape Scaffolding with Fasteners1） C3070塔高40.35米，直径1.5米，需要安装层8个平台和7个直爬梯（安装位置见下表），搭设5m×5m的双排井字脚手架。The column C3070 is 40.35m high, its diameter is 1.5m, and 8 platforms & 7 ladders are to be installed (installation locations see the below table), so double row “#”-shape scaffolding 5m×5m shall be erected.Platform&Ladder安装标高mmInstallation Elevation mm安装角度Installation Angle（0°为正北）(0°is True North)宽度Width mm长度Length mmPlatform1EL：4300135°320°1200Platform2EL：652790°180°900Platform3EL：10500190°245°1200Platform4EL：16000230°210°1200Platform5EL：23815200°320°1200Platform6EL：3150090°210°230°350°1200Platform7EL：37950190°330°1200Platform8EL：40250around550Ladder1EL：05470335°5470Ladder2EL：430010500180°6200Ladder3EL：1050016000220°5500Ladder4EL：1600023815335°7815Ladder5EL：2381531500220°7685Ladder6EL：3150037950330°6450Ladder7EL：3795040250210°23002） 搭设时，以双排架的形式搭设，以保证架设的稳定性，且里层架杆必须距塔壁有一定的作业距离。Try to erect in double rows to ensure the stability of scaffolding. The inside scaffold poles must keep a certain distance from the tower shell. 3） 所搭成的架设须整齐规范：立杆、横杆均须均匀布置，立杆在一条垂直线上，横杆在同一水平面上，扫地杆应沿纵向、横向连续搭设且距地面200mm。立杆采用双立杆，立杆纵距小于等于1.5米，横距不大于1.3米；大横杆步距不大于1.8米。The erected scaffolding must be in order and standard: The rickers and cross rods should be arranged uniformlyrickers should be in the same vertical line and cross rods should be in the same horizontal plane. Erect the bottom horizontal tubes continuously both longitudinally and transversely, 200mm above the ground. Use double-ricker,The longitudinal space between rickers should be 1.5m or less, transverse space should be 1.3m or less; the
