Hello forum
The floor in my old house has a dip due to old water damage and a poorly executed old renovation. This has resulted in the wall being a bit "happy" as the upper floor has also followed down, so to speak. This wall is in line with the roof ridge, and I was thinking of trying to level the floor next summer, but I won't attempt to push up the upper floor as it would be too much work. However, I need to support the "happy" wall with posts and beams on each side of it. To avoid the posts getting in the way of the new floor joists, I plan to have at least 4 posts under each beam, where I can install a fifth post and remove an old one while building the floor. Eventually, a new wall will be erected on the floor to replace the old one. However, it might not be in the exact same place, which of course requires that the intermediate floor joists are not generally spliced over the existing wall. With at least 4 posts on each side of the wall, I am now wondering how strong the beams need to be. All measurements can be found in the picture; at most, there will be 2 meters between posts. The total length of the beams is 4.5 meters and 4.0 meters, and it is wall B that will be demolished. The beams are only drawn on the upper drawing.
Here, the chimney stack also comes into the "picture" with its "wing," which I have long speculated about the reason for its existence. It definitely supports one or two floor joists on the upper floor, and up there, a wood stove was built directly on the floor covering, which became a considerable weight on less than a square meter that needed some reinforcement from below. (However, this is just my guess; I have asked the question in the forum once) There was also some fire protection on the ground floor. (the stove on the upper floor has been removed)
The chimney stack's "wing" "assumed" load-bearing capacity is not taken into account as my temporary construction beams run parallel from the outer wall to inner wall E and D.
How strong do the beams need to be here?
And how far from the existing interior wall can I place them?
Best regards, Hans O
