Each group of bridging across poling root number is 5 ~ 7 root; Highly under 24 m single and double row scaffolding, must be in the outside elevation at each end of a group setting, with scaffolding set-up continuous set of from bottom to top; Height at 24 m double bent over, along the length and height in the outside facade must have continuous settings; Bracing diagonal should be level with that of the stud and out connection rod; Bridging the diagonal extension adopt lap. 

The master node must set a lateral horizontal pole, with a right-angle scaffolding fastener hooking and it is forbidden to dismantle; Homework layer on the main node of lateral horizontal bar, should be set according to the needs of supporting scaffold board and so on spacing, the largest spacing should be not more than half of the longitudinal spacing. 

Dismantled before the preparation work: a comprehensive examination of scaffolding fasteners connection, even the wall parts, supporting system is in line with the construction requirements; According to test results complement construction scheme and measures, in the demolition order after approved by the competent department in charge of their implementation; By engineering construction, head on safety technical disclosure; Clear the clutter on the scaffolding and ground obstacles. 

Demolition should be: demolition work should be carried out step by step at top-down, forbidden and homework at the same time; Even the wall must be demolished along with step by step a scaffolding, forbidden to connect wall again after a whole layer or layers of demolition dismantled scaffold, segmented demolition of elevation difference should not be greater than 2 steps, such as greater than 2 step should be to establish even the wall a reinforcement.
