Attach temporary wooden stud to concrete for scaffolding

[nyanv]

Hello!

I am planning to repaint the stairwell and therefore need to build a temporary scaffolding. My plan is to attach wooden beams to the concrete wall with crossbeams. On top, I thought of placing an OSB board to stand on. Quick sketch below:


How can I attach the beam to the wall so that it's sturdy and easy to remove when I'm done?
I spontaneously thought that universal plugs should suffice?

Use a facade plug type: https://www.fischersverige.se/sv-se...uv-med-sexkantshuvud/522720-sxrl-10-x-100-fus

Go for a facade plug type:

I used facade plugs 10x140 mm and it worked well - thanks for the tip!
I chose to use longer plugs when I learned about the rule of thumb "2/3 of the screw should be in the facade."

A wall plug is adapted to the thickness of what you need to fasten and whether it is concrete or lightweight concrete. It doesn't become stronger by setting it deeper as the expanding part remains the same.
