Renovating beam layers ceiling/floor - Problems and questions

Am I the OP?

Am I the OP?

Oh, no, but generally I dare to make the bold assumption that the answer to this question can also be found in the mentioned source. I assumed that the question refers to the intended structure (see the said technical literature) – the actual structure was described by the OP:

that in my old building the intermediate ceiling is a beam layer. Below, these were covered with drywall sheets and a wooden structure.

Evening,

sorry that I can only get back to you now. I was just cleaning the kitchen door...
so the structure is:
Rigips - battens - beam layer
In this setup, it is not intended to hold extreme weight. Therefore, my idea is to put mineral wool/wood fiber wool in there. Although thermal insulation is not important.

I will read the PDF from "ift Rosenheim" tomorrow.

In that sense, thank you very much in advance and have a nice Sunday evening!

You will find several that partially overlap and all represent construction examples.

Therefore the inquiry regarding IST. The joists are only the 180s. It is now clear that there is practically nothing there.

Hohlkörper aufzufüllen (keine Glaswolle!)

rgesehen, dass extremes Gewicht gehalten wird. Deshalb ist meine Idee, dort Steinwolle/Holzfaser-Wolle hinein zu stecken

Yes; so what now? If the construction is not really supposed to get thick on the joists, load-bearing inserts are needed and on/ between them a proper filling

That's why my idea is to fill it with stone wool/wood fiber wool.

But that won't solve your impact sound problem. Weight is key. If the blind floor doesn't support much, and you don't want/can't reinforce it structurally: If you have enough room height in the upper floor, you can lay OSB boards on the joists and then add your weight using dry mineral infill/concrete block ballast. On top of that, an impact sound insulation board and screed with floor construction. However, you need 15 - 18 cm above the joist, and it must be able to support it.
