I have an old barn used as a garage. It's a turn-of-the-century building that has been remodeled multiple times in various ways.
In about one-third of the barn, there is a concrete slab, and in the other, there is a concrete slab with a wooden floor above, but between these, there is topsoil where there used to be an earthen bank that was much higher than the other two floors. I intend to pour a concrete slab there to create a uniform and even floor throughout the building.
Between the wooden floor section and the topsoil, there is a foundation wall and a cross beam in the ground on which a post stands. This post supports the intermediate ceiling... The issue is that I need to get rid of the cross beam and cut down part of the foundation wall to get everything at the same level. But I can't do that since the post stands on both.
I assume the post won't remain if I try to remove the sides of it. So, I see these options:
1. Can the roof truss be redesigned on top of the intermediate ceiling to be self-supporting and without posts? This truss can essentially be designed in any way, either H or W?
2. You should be able to set up two posts, between the current post and the outer walls, to support the roof on both sides instead? Then I can remove this post in the middle. However, the problem is that it's an earthen floor, so I would need to place something in the ground for the new posts to stand on. Either set posts or temporarily use paving slabs on the ground and prop up?
3. As 2, but with the posts all the way to the walls.
Preferably a permanent solution as the post is in the way anyway, but I'm also satisfied with a temporary solution until the new floor is poured and then I can replace the post.
Paint skills of what it looks like:
Or one of these options to support. The above 3 options are quickly illustrated
This is how it really looks:
The post in question is nailed against the cross beam holding the intermediate ceiling:
The cross beam along the ground on the earthen floor and the foundation wall. It stands about 50/50 on both and is nailed to the cross beam.
The same but the other side of the post, more of the foundation wall remains here. I want to level everything down to the same height as the wooden floor.
A jack to lift the roof a little and insert 2 posts on each side about 1 meter from the wall you are going to demolish, for the base of the posts you can place one or two cement slabs 300X300 on the ground, it holds well.
PS Just noticed that the joists are perpendicular, so there will be a strong beam in the ceiling across the joists, which results in the same transition as you have now.
PS Saw now that the floor structure is across, it will then be a strong beam in the ceiling across the floor structure, then it will be the same bracing as you have now
You mean I could have done it like this, i.e., placed a strong beam from the ridge to the beam for the intermediate ceiling? And then I can remove the post underneath?
Maybe I expressed myself a bit incorrectly with avväxling, I meant to support while you arrange it with the demolition, it's far over there and maybe not good to växla av like that. I'm not an engineer who can give advice on this, just with supports and to put back one or more posts on the finished floor. There are people on the forum who know about structural strength,
