Divide room with gypsum partition

[Lyckan01]

I'm going to divide a room with a partition wall and now have a few considerations:

The floor in the room is parquet with concrete underneath, the dilemma is whether to remove the parquet where the wall will stand and fasten the floor plate to the concrete, or place the plate on the parquet and use double-sided tape to lay the plate on?

The ceiling is concrete, so I'll screw a ceiling plate there, and one wall is concrete, so I'll screw a wall plate there, but the other wall is drywall, should I also fasten a wall plate to that wall?

Otherwise, I will use studs 40*70 OSB and single drywall.

Welcome to the forum!

It's sufficient to attach a new wall to the ceiling and along the sides. Against the floor, it will be stable due to the pressure from the standing studs.

I once saw a TV program where Timell put up a partition wall in a rental property where you weren't allowed to affect the floor.

Assuming the wall doesn't become longer than 4-5 meters, it's fine without fastening it to the floor.
If I had done it, I would have cut both the rule against the floor and the standing rules to a slight overmeasure. Not by much, but enough so that you have to tap them into place. Then the bottom rule will also lie steady.

It works. Tighten the standing studs firmly against the floor and preferably place some flexible material underneath. I have built two such walls. The first one "released" after a year. I think it was because the wood shrank as it dried. For the second wall, I placed a piece of rubber sheet under the floor stud when I tightened the standing stud. It's rock solid.

I would probably avoid tape. It might become a sticky mess that damages the parquet.

if it is floating parquet flooring, you should not tighten the battens too hard, maybe better to secure with a few 2 1/2" nails in the parquet

Provided the wall doesn't exceed 4-5 meters in length, it's fine not to attach it to the floor. If I were doing it, I would cut both the floor plate and the vertical studs slightly over-measure. Not by much, but just enough that you have to tap them into place. Then the bottom plate will also sit firmly.

Great, the wall is short, about 3.2m. I will not screw down the floor plate but instead follow the advice to tap the vertical studs into place.

Tape with yellow construction tape on the parquet, then on that construction tape attach the floor rule with double-sided tape. Easy to remove later...
