level floors?

[trojlee]

Probably need to level the floor when we tear off a lot of parquet and lay down chipboard flooring and then new flooring. What dimensions should the wood have that you're leveling with, i.e., screwing alongside the joists... fixed at the "right" level...? Anyone have tips?pictures?
Thanks in advance

The dimension must accommodate the screws you use to attach to the floor joists. If you want full load-bearing capacity for the 22mm chipboard and you have x meters in span, check what the literature says about center-to-center measurements and dimension. If your existing joists meet this requirement, 145x45 is sufficient. Use a French wood screw with a washer, 60cc, and glue. Properly brace the floor, preferably where you get cross joints on the chipboard.

so it's French wood screws that are needed? Where you kotte, how do you make the attachment to the joist?

You don't need to use franskskruv, if you use limskruvar it will hold with 6x90 screws.

French screw is a nuisance and should be legally banned.
(I think)

Nail straight through the floor joist directly into the kottling.

Leveling the floor is relevant for me as well. I have floor joists on the upper floor with a center-to-center distance of about 65 cm. Just like TS, I am about to lay floor chipboard and need to level in both directions, meaning the floor slopes inward from all sides towards the center of the house. I'm thinking of using 45x195, gluing, and nailing with 5", is this insufficient according to some opinions? Is a screw better and/or easier to fasten with...?

Is it enough to place a new stud on one side of the existing joist, or must it be on both sides? Considering that the center-to-center is slightly more than the standard 60.

If you put one on each side of every beam, it will be cc 60, right?

 

[BobLewis]

If you put one on each side of every beam, it will be about cc 60?

Well, almost, it becomes the current cc which is 65 cm.

In this thread, there is a picture where there are studs on both sides. http://www.byggahus.se/forum/golv/140446-rikta-golv.html

The floor joists are quite twisted too, see picture, it's probably going to be a bit of a puzzle to attach the new and old joist together??
I mean, you want the new one to be vertical and then there won't be much surface between new/old for the glue to work on. At the same time, the new joist will want to twist the same way when nailing them together....

Aligning floors is also relevant for me.
I have floor joists on the upper floor with a cc distance of about 65 cm.
Just like TS, I am about to lay chipboard flooring now and need to align in both directions, i.e., the floor slopes inward from all directions toward the center of the house.
I was thinking of using 45x195, gluing and nailing with 5". Is this insufficient according to some opinions? Is it better and/or easier to attach with screws...?

Nails are perfectly sufficient.

I mean, you want the new one to stand vertically and then there isn't much surface between the new/old for the glue to work on. At the same time, the new joist will want to twist in the same way when you nail them together....

I have the same problem with my beams, what solutions are there for this?

Wedges.

 

[Kyling]

On top?

As padding between the old twisted beam and the new ones so that they stand straight.
