Hi All,
I hope everyone is well. Nice to 'meet' you all!
What do ye think of this solution, suggested to me........
If we have a system scaffold standard with is over loaded, the solution is to connect a tube standard onto the side of the system standard with swivels so that the tube standard can take half of the load from the system standard.
I don't believe that this works but I've seen it done a few times and I'm wondering am I correct in querying it?????
To me it seems that the load path is..... load on boards, to system transom, to system star, to system standard, to base jack, to sole board, to ground.
I can't see how half of the load can jump horizontally across to the tube.
Am I right?
Recently I designed a beam in a system scaffold to support two slung standards.
The system standards supporting the beam at each end would have been over loaded so I put in an extra tube at each end of the beam to support the beam load and I let the system standard support its own weight only.
When I saw it on site the beam had been connected to the system standards at each end and there was a tube connected to the side of the system standard with swivels (similar to the situation above and tube standard not connected to beam chords).
To me, this tube standard is not supporting any vertical load.
There was even a gap of 10mm between the tube standard and the base plate so it couldn't be supporting vertical load.
The only benefit I can see to the extra tube is providing a bit of resistance to buckling, but I'm not sure how I would quantify that.
Any thoughts or experience of this?
Much appreciated Folks!
