Panel material load-bearing wall

[amoreex]

Hello!
I am going to renovate a room and put OSB on the walls.
One of the walls is load-bearing with 45x70 and cc40.

Today there is 15mm raw paneling.

Am I thinking correctly by putting 12mm construction plywood on the load-bearing wall instead of OSB?
I think it should be about the same strength.

Thank you in advance!

I believe that both OSB and construction plywood are better than rough tongue and groove in load-bearing walls.

really?
Because today the house is built with 45x70 cc40 15mm raw board and 9mm gypsum on load-bearing walls.
And 45x45 cc60 15mm raw board and 9mm gypsum on other interior walls.

If the raw paneling is set on the diagonal, the wall is stable, but if the paneling is stacked from floor to ceiling, it is not as laterally stable.

If the decking is set diagonally then the wall is stable, but if the decking is stacked from floor to ceiling then it is not as side stable.

Okay!
Had an interior wall opened earlier and it was stacked. Meaning horizontal.

another thought.. should one use supports when removing the decking?
Or do the studs hold anyway?
There is decking on the other side and the wall is only 2.2m wide

One could say it's a partition wall. Where this room is just a part of the wall

The risk of something happening is small if one side of the beams is supported by lateral forces, but to be 100% sure, you should support from floor to ceiling if you plan to operate on a load-bearing wall.

The annoying thing is that the plan is to tear down all wall coverings and even the floor.
Since it will be renovated in the space, and the floor needs to be re-studied.
Hence, it's more complicated to have props standing around.

And since the ceiling will also be replaced, the prop is in the way there too.

Place a diagonal brace across the wall, e.g., a 22x95 board.

Place a diagonal brace across the wall, for example, a 22x95 board.

Is that enough?
The house is located in western Blekinge.
So no significant amounts of snow are likely to come for the rest of this winter
And it's 1.5 stories.

You have remembered that interventions in load-bearing structures require an approved building notification before work can begin.

even if you're just replacing with better?

if I replace with råspont then?

Here is how Boverket puts it:

You need to notify the following if building permission is not required:
...
change involving the construction of a building's load-bearing parts ...

For me, it sounds like load-bearing parts are affected.
But you can always check what your municipality considers the boundary.

This is how Boverket phrases it: [link]

But you can always check what your municipality considers to be the limit.

I'll have to look into that.
At the same time, it feels a bit unnecessary when it's not deteriorating in any way..

One thing that struck me..
Checked the building permit.
The interior walls are modularly built.
Both exterior and interior walls are modularly built.
Does this matter for how to proceed?
Or does it only mean that they have assembled the sections in a factory and lifted them into place?

Nothing that affects during renovation?

Everyone tries to compensate for the removal of load-bearing walls to avoid any deterioration. The building permit is meant to enforce this.

Something that struck me..
I checked the building permit.
The inner walls are modular.
Both the outer walls and the inner walls are modular.
Does this matter for how we proceed?
Or does it only mean they assembled the sections at the factory and lifted them into place?

Does it affect renovation?

In that case, many more and different walls might be load-bearing and/or stabilized compared to houses not built in modules. Each module is made to be stable on its own. A structural engineer with knowledge of modular houses is recommended.
