Floor beam, log house - rotten end grain

[Marcussjogren]

Hello!

I'm working on repairing our log frame and found this floor joist which is apparently just lying on the lime plaster.

It might be nailed as well, the big nail in the picture suggests that.

Do you have any suggestions for addressing this? The previous owner had just put a couple of blocks in the hole, which doesn't help much here.

One idea is to try to lift the floor and screw the joist together with two 45x145 and joist hangers in the wall or something similar. We can also hope that it is intact on the inside and maybe screw a piece of wood into the timber that it can rest on.

I want to stay as close to the old building techniques as possible and make as little impact on the old as I can.

The grey you see is thus reed-reinforced lime plaster.

Can you cut the beam a bit, replace with new timber and splice according to this image?

I continue to discuss a little with myself

It seems that it is not a free-hanging beam and it lacks a joint function as far as I can see, it is simply inserted into a notch.

Thus, it should not pose any danger to the house to leave it as it is and then lift the floor at a suitable time and remove the bad part and splice in new wood. Possibly a dowel into the underlying log as well.

Well, I finally had the chance to take a closer look, and it was my mistake. The beam is hanging freely in the ceiling without support.

Any idea on how to fix it and how critical it might be?
I guess I actually need to open up the ceiling to find out.
