Hello all happy "craftsmen"
It has now been decided that the wall between the kitchen and the living room will be demolished.
Unfortunately, there is a concrete column in the wall to support the upper floor, so I have to alternate this if it is to be removed.
I haven't calculated any loads yet, but it will probably be an HEB140-HEB160 steel beam that will be about 4200 long.
Now to my question:
How on earth should this steel beam be installed?
Does it need to be anchored to prevent it from twisting/toppling, and if so, how?? Or is it enough to "place" it on wooden pillars?
Is there any ready-made fastening bracket that can be purchased?
An alternative might be to buy a glulam beam, cut into it, and place the beam inside... or am I completely off track??
Grateful for answers!!

Hello, it is sufficient to drill appropriate holes in the lower flange over the wooden posts on each side and screw down into the post with, for example, French wood screws. You might also need to do the same in the upper flange if the posts are not well anchored.
It is "only" lateral forces that these screws need to hold, I assume you have a flat ceiling above the beam?

When you have calculated the load, you need to determine if wooden posts are sufficient (calculate for buckling).
As an alternative to wooden posts, you can use a suitable rectangular profile of steel and weld these to the beam. (We used steel, but the beam weighed 800 kg, yours may only end up at 200.)
Glued laminated timber of the same stiffness as HEB will be significantly higher, approximately double, I would guess.

Ask the company you are buying the beam from to weld a knap onto it, i.e., flat iron or plates which you then screw the posts into with bolts or through bolts. It is not uncommon to weld nail plates onto load-bearing beams that are then nailed to the posts. If the posts are stable, it will take a lot for them to fall off...
