1.脚手架搭设要求
(1)Requirementsofscaffoldingerection
（1）脚手架斜道外侧和上料平台应该设置高1m的安全栏杆和高18cm的挡脚板或挂防护立网，并随施工高度升高而升高
Theoutsideofthescaffoldrampandthefeedingplatformshallbeequippedwith1-meterhighsafetyrailingand18-centimeterhightoeboardorhangingprotectivenet,whichwouldrisealongwiththeconstructionheight.
（2）脚手板的铺设要铺满，铺平和铺稳，不得有悬挑板
Thelayingofthescaffoldboardshouldbefull,flatandstable,andthereshallbenocantileverboards.
（3）在脚手架的搭设过程中，要及时设置连墙杆、剪刀撑及必要的拉绳与吊索，防止搭设过程中脚手架发生变形、倾倒

(2)Electricpreventionandlightningprotectionrequirementsforscaffolding
（1）脚手架与电压为1-20kV的架空输电线路的距离不应小于2m。
Thedistancebetweenthescaffoldingandtheoverheadtransmissionlinewithavoltagebetween1kVto20kVshallnotbelessthan2meters.
（2）施工照明通过钢脚手架时，应使用12V以下的低压电源。
