What is the previous version of the scaffold fastener (JGJ166-2008) for construction? That is, the implementation of the current version of JGJ166-2008 will soon be replaced by 2009.7.1 version.
In addition, I did not hear that JGJ166-2008 has a new version of ah, it is JGJ130-2001 "construction of steel tubular scaffolding safety technical specifications" in the second half of the new version of JGJ130-20112011 December 1st implementation
What does the previous version mean? Once the new version comes out, the previous version is cancelled
Jgj166-2008 is the first safe and technical specification for the construction of steel tubular scaffold
