I've searched and found some things but not quite exactly...
I have an L-shaped staircase to be mounted in a corner of Leca + about 10mm plaster. The longest stringer will be against 190mm Leca, and the short one has only 90mm to attach to (Isoleca).
At first, I thought of anchor adhesive + threaded rod, but then it would be very difficult to take down the staircase later if needed. The threaded rod will stick out a bit, and it's impossible to slide the staircase sideways much.
I've used regular Thorman Blue (10mm) plugs in enlarged 8mm holes in Leca elsewhere, and it's solid as a rock, but it feels a bit too weak here. Leca screws are out of the question; I've tried them and hate them!
The staircase hangs by its post and at the top and is really just held in place sideways against the wall, but I want it to be secure and not start to loosen or anything.
Leca anchors? Or something else? Does anyone have experience and can offer tips?
