[Haichuan Civil Engineering Issue] For the exterior double-row scaffolding bracing in the main structure construction, should there be one or two vertical poles?
Thread Content
For the exterior double-row scaffolding connecting members used in the construction of the main structure, should they be used to connect only the inner vertical poles (Figure 1), or should they connect both the inner and outer vertical poles simultaneously (Figure 2)? I believe many people have gone through the relevant standards repeatedly, but none of them specify that connecting members must be connected to both the inner and outer vertical poles; the standards merely state that at heights of up to 24 meters, flexible and rigid connections should be used at the main joints. I’m sure that both approaches are used on construction sites, each with its own reasons for adoption. Which approach is used at your site?
It is this aspect that can lead to misunderstandings. From what I’ve seen in the discussions, people are saying that two are required; it’s just not convenient to use two safety nets
