Hello
I am in the process of expanding the house. The extension is about 4x12m, all the walls are built in leca, and the intermediate floor will be cast in place.
The three interior walls are also load-bearing. Due to the fact that the interior walls are load-bearing, there will be no large span.
The plan has always been to have steel beams in the intermediate floor, but now the builder recommends reinforcing the intermediate floor instead to save space. He then wants to reinforce with a heavy reinforcement.
What do you think about this? Is it a common solution to reinforce instead of using steel beams? Do you have a good link where you can read about cast intermediate floors?

I am going to build a hillside garage with a basement with a similar construction as yours (LECA walls and cast-in-place intermediate floor). The size is 7.1 * 4 meters without interior walls, and the designer I hired has not specified any beams on the drawing but instead reinforcement mesh 8s150 at the bottom of the slab + stirrups and iron in the "votes" on the sides.
hello! you don't mention the thickness of the arch. is it you or the builder who will make the arch? use reinforcement above and below on the kattfötter. with concrete, you can almost do anything. check what a finished arch would cost, with transport and lift.
It is the builder who will make the vault. He recommended a 15cm vault, then insulation, and finally a smaller layer of concrete where the underfloor heating will be for the upper floor.
Thobias: How thick will the vault you cast be?

15 cm sounds weak. Then it will be like outside of Stockholm maybe. On the K drawings, there was a measurement, but they skimped a bit, saving some money, but it backfired. The thing with 15 cm being weak is just speculation on my part. Hasn't any engineer calculated it? A reinforcement drawing is needed as well. Is it intended that the frigolite should lie loose on the first casting and then be pressed down with the next casting? Use Wirsbo's or Rooth's underfloor heating system (great). A bit depends on what kind of floor will be on top. On parquet, the frigolite is laid loose, but where tiles come, the frigolite is glued.

They will reinforce with 16mm reinforcement. They will also build a "beam skeleton" of 8mm reinforcement, which will then function as a beam. So the concrete won't be so thick, but it is compensated with substantial reinforcement.
What do you think, will it hold?
I haven't had a structural engineer calculate the construction, but the builders (Polish) have used their experience.
At the beginning of the construction, I had an external construction consultant come out and check what they had done so far. He thought everything looked very robust and well-dimensioned.
I should probably bring him here again and let him check the intermediate floor.
The Frigolit will probably lie loose; I will have parquet on all floors.

Poles often think that Swedes reinforce unnecessarily.
I would have cast 20cm thick. Consult an engineer just to be sure. Beams might be needed, and they should look a certain way. The net thickness and density on the top and bottom must be correct. The supports may need to be constructed in such a way that you drill in iron into the lecablocks, which are fastened with chemical anchors.
Directly in line with the load-bearing walls, extra transverse reinforcement at the top may be needed to prevent breaking forces.
If you want quick underfloor heating, you build up the formwork construction with formply, for example, 150mm below the floor's bottom edge (UK) and place 150mm thick cellular plastic, then UK reinforcement, then underfloor heating coils, then ÖK reinforcement.

Why do you need to insulate under the floor heating to the upper floor?
I don't realize what the problem would be if you get unintentional ceiling heating in the lower floor.
Do you want a lower temperature in the lower floor?
