Bearing partition wall or?

[SveaSvensson]

Hello

I own a house built by Smålandsvillan and am considering possibly opening up between the kitchen and the living room. The wall I want to tear down runs through the middle of the house across the roof trusses, and I assumed it was a load-bearing heart wall. The wall is 140mm wide and consists of two 45x70mm studs screwed together.

Floor plan and marked wall that may possibly be torn down:



I removed the chipboard over the current opening, which is 1410mm, and expected a beam, but instead there was nothing I considered load-bearing.

They simply nailed two 45x70 studs between the columns, and it is thus not load-bearing. The 45x70 stud attached to the ceiling is also spliced before it reaches the column.

Sketch of the "support beam" where I marked the splices with bold lines:



Picture of the splice at the right column:



Drawing of the roof trusses:



Is this wall simply not load-bearing, or have the people who assembled the house simply skipped installing the beam over the current opening?

Seems like you have an upper floor, so the wall is likely load-bearing.

You have the truss numbered at several nodes. Could it be that there are some forces specified at those points somewhere on a drawing?

That's correct that I have an upper floor with a dormer, I will check the drawings tomorrow and see if there's anything mentioned.

If that wall is load-bearing, then the beam construction must be completely wrong...

If the floor on the upper floor feels sufficiently stiff when you walk on it and you don't have any deformations there, then the bridging is probably not a problem.

There is probably good hope that you can perform this intervention by installing a bridging beam. However, it is recommended to hire a structural engineer who can calculate this beam and also make an assessment regarding how the house's stability will be affected concerning wind load.

How has it gone with this? We have the same house and are wondering how we can proceed.

How did it go with this? We have the same house and wonder how we can do it.

The wall is load-bearing, if the opening is to be enlarged, it should be replaced.

The wall is load-bearing; if the opening is to be enlarged, it must be braced.

Best regards

Hi! Absolutely, but did you remove it, and how did it turn out? Any problems or oddities along the way? We will send the house plans to a structural engineer to get a construction drawing.
