Firstly, it should be noted that the connecting wall components bear the inward or outward tilting force of the scaffold, and their design does not have the function of bearing the settlement of the scaffold



To get to the point, let's first take a look at how the specifications specify wall connecting components. JGJ130-2011 Safety Technical Specification for Construction Fastener Scaffolding, Articles 6.4.3 and 6.4.6 stipulate:



We can understand it as, under the premise that the calculation meets the force requirements and the spacing meets the standard construction requirements

As long as we meet the above two conditions, the connecting wall components are qualified

Let's take a look at the various wall connecting components that appear on the construction site, combined with pictures; The following analysis is purely based on personal opinions!

1. Class representative type

The wall connecting component in this picture connects the inner and outer uprights, which is very beautiful

So many regulatory authorities have mandated that wall connecting components must be connected to external uprights

I am foolish and cannot find that regulation in the code. (Currently, there is a saying: Do scaffolding wall connecting components have to be connected to the inner and outer uprights at the same time?)
