What should we pay attention to when disassembling scaffolding?

1. According to the design plan of scaffolding erection for exterior wall and considering the construction requirements of other projects, it can be distinguished that the scaffolding is partially removed from the demarcation line. Generally, it can be distinguished by the angular orientation or the orientation of connecting rods and lateral braces. The East facade is removed from o17 axis to O4 axis, the south facade from oA axis to oF axis, and the West facade from O4 to 1/10 axis.

2. Before partially removing the scaffolding of external wall, it is necessary to check whether there are rigid connecting rods and lateral braces at the end of the mobile scaffolding which cannot be removed. If not, it is necessary to add rigid connecting rods and lateral braces at the end of the mobile scaffolding before partially removing the portal scaffolding.

3. Before partially removing the external wall portal scaffolding, check whether the shear braces on the outside facade of the trapezoidal scaffolding cannot be removed are connected. If not, it is necessary to remove the demarcation line with the trapezoidal scaffolding and install the shear braces on the outside side of the scaffolding that cannot be removed before removing the scaffolding.

4. When some scaffolds are removed, the longitudinal crossbar or diagonal shear brace should be extended within the scope that cannot be removed. It is necessary to cut and extend the steel pipe in the direction of the demarcation line. It is forbidden to connect the short pipe after the whole scaffold is removed.

5. When some scaffolds are removed, they are removed to the end of the demarcation line. It is necessary to install guardrails and hang safety nets at the end where they can not be removed. Scaffolds are laid on flat bridges.

6. When removing part of scaffolding, when removing three layers and not exceeding 10m, we should check whether the scaffolding can not be removed and whether the scaffolding construction meets the requirements and specifications; if not, we should make corresponding treatment adjustments to meet the requirements of the specifications. Whether the fastener is loose or not, especially with the removal of the connection, should be tightened.
