I need help removing the wall.

Hello community.

Brief introduction: I have just become a member of hausbau-forum.de as well. Two weeks ago we bought a small house built in 1926. Now I am ready to remove a wall.

And here comes my question: Is it sufficient to place a beam approximately 12x16 cm underneath, lay it on the inside on a 47 cm wall, and support it on the outer wall with a post 12x16 cm underneath?

There is already a ceiling beam of 12x17 cm on the wall, on which there is a thin wall made of tuff stone on the upper floor.

In the upper part of the wall there is also a part of the roof structure. I am not concerned about this because the forces are transferred to the outer wall.

Here is a picture of the current situation:

Further information will be provided if needed (Want to save myself some typing work :))

Thanks for your help

... this is how it should be:

Hello Sicky,

no hard feelings, but you want to build the house up, not tear it down, right? Without a structural engineer, you won't get anywhere. Although I am also a 99% DIYer, I don't touch structural engineering. That's why both my house and I are still alive today.

Regards

@Allrounder: Thanks for the quick response! I hope someone who knows about statics will also chime in. The task is quite simple: a span of 3 meters needs to be supported. The load is known: 2 tons. There is already a beam 12x17 cm. It can already bear a lot. Another beam should be placed below it: my idea is 12x16 cm. A good structural engineer can say without calculating whether it fits or not. I just hope someone like that reads my post :) :o Regards Sicky

Hello,

If I stack existing and new beams on top of each other, I then have about 33 cm height. For the calculation, I only entered 24 cm and increased the estimated load from 2 tons to 2.5. Additionally, I added other loads (snow, traffic load even though there is none). The result was positive. Picture:

An online calculator does not replace qualified advice. I would not do this without a structural engineer, even if I found 10 calculators on the internet. I wouldn't even know what to enter there.
