Which occasions are not suitable for building single row scaffolding

May 15, 2019

A single row of scaffolding is a scaffold with only one row of poles and one end of the short rail resting on the wall. Therefore, from the perspective of safety protection, single-row scaffolding can only play a certain protective role, and can not be extraordinary. Naturally, there are occasions when it is not suitable to build single-row scaffolding.

 

Generally, buildings with a wall thickness of less than or equal to 180 mm are not suitable for erecting single-row scaffolding. Because such buildings have limited load-bearing capacity, the consequences of forced construction may cause serious consequences such as the collapse of the external walls of the building. The height of the building exceeds 24m. If the height of the building is too high, if the single-row scaffolding is built, the center of gravity of the scaffold may be unstable, which is not guaranteed for the safety requirements of the workers, which is a potential safety hazard.

 

Lightweight walls such as empty brick walls and aerated brick walls are not suitable for building single-row scaffolding. It is also because of the problem of bearing capacity. Such walls should be constructed with double-row scaffolding. Brick walls with masonry mortar strength grades less than or equal to Ml.0 are not suitable for single-row scaffolding due to their own material problems. Therefore, the first step in the design of mobile scaffolding is the weight-bearing effect of the wall. The material, height and thickness of the wall must be considered.
