I am planning to build a conservatory under a load-bearing exterior wall and will have two columns that are 10 meters long.
If I am going to have insulation under this column (still somewhat unclear), it needs to be a more durable variant there, but the question is, over how large an area?
I would guess that it's not enough with exactly these centimeters directly under the column, but it's reasonable to assume there's a large load over a bigger area due to the stiffness of the slab, but how large? Is 60x60 cm enough for a centered 14x30 cm column, or should I have a larger area with more durable insulation? The rest of the area is with a significantly cheaper S100 insulation (instead of 250 or alternatively 300).
I'm trying to Google it but can't find anything. It also doesn't seem like the insulation manufacturers mention it, so I assume that fairly "local" reinforced insulation is actually enough.

Half of the post will actually be on a masonry lecawall and the other half on the slab.
60x60 was just to be a bit frugal/smooth, to just split them in half. But that was mostly an example.
But there must be some kind of recognized method within the industry, right? I know that craftsmen often skimp on insulation, which is probably to the annoyance of the designers, but at the same time, it's rarely I hear a designer comment on insulation at all, so it feels a bit like an area left to chance. At least according to my modest experience.

First and foremost, the plattan must be locally reinforced to withstand the pressure from the column; this is a job for an engineer to calculate so that the thickness of the concrete and reinforcement are correct.
With a properly dimensioned slab, I don't think the insulation requires anything special.

This program might help you.

As an open demo, without purchasing a license, there is a load case.

Thanks for the tip. I'm not quite sure if it will help me, I don't feel like I entirely have the prerequisite knowledge to understand what the program outputs.
But one thing that is clear is that the columns will be approximately 50% on lecasten and the other half of the column will be on a cast slab.
The slab is thus cast within a wall of lecasten. The stone should be able to support the columns without issue, but I'm wondering, is it wise to reinforce the top row of stones with the slab? For example, should I drill holes in every other stone and insert a short piece of iron that then extends into the reinforcement meshes?
