Anchoring wooden posts on concrete foundation?

[BiFuel]

Yes, that sounds reasonable. Maybe add braces in a cross shape in the ceiling plus the balcony floorboards to stiffen it up? It's attached to the house as the two inner corner posts are nailed into the house wall. Fastened with 7-inch nails or similar

OK, so hinged fastening can work. Would that be better than my suggestion with threaded rods?

The previous posts weren't even attached to the foundation. They just stood straight up and down.

Here's one that resembles what I was thinking of doing, but this one should be bolted instead of cast in. I'd gladly accept tips/links to better or more suitable products.

Another similar (or the same?) product. Wouldn't it be possible to embed one of those instead? I think there is a risk of drilling holes for bolts about 10 cm from the edge of the foundation.

Joma has many variants that would work for you, as you have already seen. If you haven't cast it, the easiest thing is to send down a column shoe into the concrete. For example, http://www.joma.se/timber-connectors/column-shoes/hero-stolpsko-justerbar-typ-flex.
All of these are considered articulated fastenings.

There's no problem drilling 10 cm from the edge, but it's unnecessary, much easier to cast in.

A fitting on each side of the pillar as shown in the image.

Thanks for the help! We're finishing the casting mold this weekend so I'd like to get the stuff home in time. Hopefully casting soon thereafter. Should I interpret this as my idea with threaded rod is not good?

A mounting on each side of the column according to the picture.

But there the column is standing on the concrete. Want to avoid that. They will probably not be completely enclosed.

If I can't find anything, maybe I'll build 4 small "boxes", so you can save holes in the concrete and cast in the right fittings later?

Joma has, as you have already seen, many variants that would work for you. If you haven't poured concrete yet, the easiest is to send down a post shoe into the concrete. Like [link].

Yes, it felt very unnecessary to drill. You never know if you might accidentally cause a crack or something.
I'm leaning towards those Hero adjustable post shoes from Joma, and I'm calling around to see if I can get them before the weekend. They should be available at Ahlsells and Beijer in Jönköping.

I just think all those adjustable variants are quite ugly, well in your application that is.
(To that nice house, i.e.)

I think I would just try to arrange some simple plate under the post, just so the wood comes 5-20mm above the concrete surface.

 

[BiFuel]

Mikael_L, that was my first thought with the threaded rod and nut + plate, but no one here seems to think it was a good idea

We might cover the lower part of the pillar with something like a baseboard or similar. At least on the inside. On the outside, I guess we can hope it's decently concealed with the painting. Or we could cover it with a sheet of metal or something. I had planned to have a metal sheet anyway to prevent water from running along the edge of the foundation.

 

[hama65]

I would go with your suggestion of a threaded rod with a top plate and nut so you can easily adjust the height.

 

[BiFuel]

Yes, it will probably be like that. I've also discussed with the konstruktör and received positive feedback for the idea.
