Remove post under glulam beam (load-bearing)

[justusandersson]

If the beam has a longer span, it must have different dimensions. If the post is positioned far to one side, the beam should be divided into two.

If you place the post 120cm from the kitchen wall, you will need to switch to a 90x360 glulam beam. As previously stated, if you change the span, you will need to replace the beam.

A possibly feasible alternative is that it might be possible to keep the existing beam by placing two posts 150cm from both walls. Maintain a maximum span of 3 meters. But maybe that's not what you want? To go from 1 to 2 posts.
Then, of course, it's not that easy to just place a post; there must be something the post can stand on

Hello.
Returning with a thought.

Is it possible to set up a similar glulam beam next to the existing ones? That is, keep the current 90/225 and add another 90/225 next to it? Maybe glue them together and fasten with construction screws or something?
Then remove the post in the middle...

I understand that I'm probably way off base, but it would be a smooth solution if it worked.

You can pull them together with through bolts (quite a few), but the problem is that it's not enough. The smallest laminated beam you can use, I believe I mentioned it before, is 65x360.

Justusandersson, you're a hero for taking the time to respond to me and countless others. Last question.. If a post comes in 1.2 meters from the wall, making the span approximately 4.8 meters instead, what dimensions are we talking about then, or is it still 360/165 450/90 that's needed?

 

[justusandersson]

In post #19 it says 65x360. It should, of course, be 165x360. If you reduce the span to 4.8 m, you can go down to 165x315. Preferably, you should splice the beam over the post.

Welding a U-beam that is placed over the glulam could work, could prestress it with

In post #19 it says 65x360. It should obviously be 165x360. If you reduce the span to 4.8 m, you can go down to 165x315. Ideally, you splice the beam over the post.

Ok.
Of course the stores don't have these dimensions then ..
But since 315/90 is a *common type.*
If we buy 2 of those. Put them together.
Does this replace a 315/165 as proposed?

 

[justusandersson]

Does this replace a 315/165 that was suggested?

Yes, if you bolt them together. Otherwise, you can always order a 165x315. It's one of the advantages of glulam.
