We have a terrace on the house where the roof extends over and is supported by 2 columns. Now, we're planning to make some changes on the back and, among other things, remove the soil where the terrace is (they filled up with sand about 50 cm above the ground and then laid wooden decking directly on the sand, this will be removed as we plan to build a wooden deck).
We want to remove the columns and my idea is to replace them with a glued laminated beam, but I'm unsure about the dimensions and how to attach it to the brick walls.
There is 610 cm between the walls where I can attach the glued laminated beam. Above is an attic space with only wood and trusses, i.e., not insulated out in the attic and no load on the "floor" i.e., the roof out there.
The house is a 1½-story house built in '63 with a frame of lightweight concrete and a brick facade.
Anyone who can either provide tips on suitable dimensions for the glued laminated beam, or has tips on any designer/carpenter in the Eslöv area who can calculate this?
In the picture, only one of the columns is visible.
The image is a bit unclear, but if I understand the situation correctly, the roof trusses rest on a beam that is supported by the pillars. You need to hire a structural engineer to calculate that. If I understood correctly, I would think you need a beam that extends downward at least 60cm, questionable if there will be headroom under the beam. Greater chance it will work with a steel beam. It might be that the roof trusses are designed so that most of the load is taken up by the wall, then the situation is a bit more reasonable.
Those posts likely correspond to a heart wall in the house?
You can get away easier if you accept a post in the middle.
An idea:
You can place a post in the middle but further out.
This post supports a beam attached to the house's gable and rests on the post.
This then becomes support for the roof truss/intermediate floor, and a detail on the patio, a beam to hang lamps for the crayfish party or flowers or whatever interests you have.
Or that a patio roof extends from it (gable roof) or along it (clad the beam with metal above the roof).
Bring the house blueprint to a glulam seller and let them calculate. You might be able to arrange the bearings with a post at each end, but make sure it stands on solid ground, then you'll easily solve it.
It seems like there is already a beam there that the supports are holding up. I also believe in a steel beam. Were you planning to attach the beam between the outer walls? and is the distance 610 between them? There will be quite a significant load on these points. The question is whether the wall with the door/window itself is also a load-bearing part today along with these posts and beam. A structural engineer should probably calculate it. Unfortunately, I think it might be hard to find someone now during the holidays.
Thanks for the input. Yes, the image was probably bad. It's probably best to find a constructor just to be safe. I've also thought about a steel beam...
There is a gable on one side. This is how it looks:
