How do I calculate which glulam beam is needed?

[justusandersson]

So you can see the glue seeping from all the joints. Maybe 30-40 cm intervals. If you use some rigid material between the clamp and the glued area, the distance can be increased.

Now I have been to the workshop and had some items manufactured. About 15 cm, 7 cm wide, and 12 mm thick. They won't break anytime soon.

8 pcs of 45x195 studs purchased together with 8 pcs of 120x500 clamps. What glue should I use?

 

[justusandersson]

It's not my area. Personally, I've used PU glue for a beam for outdoor use. It worked very well there, but I don't know if it's best in your case.

I'm sitting and figuring out how to brace the wall when I tear it down, until I can get the beam up. It's vertical planks as far as the eye can see. On the inside, the ceiling is lowered and I can't reach any rafters, and on the outside, there are only the beams for the porch roof.

You can fasten something to the planks that you can place the stamp in. Without snow, the loads aren't quite as large.

Tips on how to get conduit through when the laminated beam is up? 195mm is thick to drill through...

 

[Lindgrenski]

You need to bolt something into the planks that you can place the prop in. Without snow, the loads aren't really that large.

I don't quite understand what you mean.
The beam is supposed to go from the lowered ceiling out to where the plank wall is today.

 

[Lindgrenski]

Solved it by taking down some of the ceiling, so now it's propped and ready for demolition. The beam is in the garage waiting for some strong men to help me carry it in.

The beam is 60 cm wider than the opening needs to be, so I plan to place it with 30 cm on each side. How much higher does the space need to be for a beam over 100 kg to be maneuvered in 30 cm? Is 1 cm enough, or will it be impossible to get it in?

 

[justusandersson]

A 1 cm play must surely be fully sufficient if you can get the beam to the right height and don't have to hold it by hand.

I plan to put supports on the wall before I tear the whole thing down, so that we can lift the beam in stages.

 

[Lindgrenski]

Does it matter how I attach the angle irons? Can I attach them to the side of the rafters so that I can do it after the beam is installed? If they need to be on the short side of the rafters, I must measure and attach them to the beam before it is lifted up.

 

[justusandersson]

I can't see that it matters.

 

[Lindgrenski]

Here's how it turned out.
Now all that remains is the rest; finish tearing down walls, run electrical wiring, finish insulating walls, insulate the ceiling, lighting, underfloor heating, and surface treatments.

A big thank you for all the help, Justus.
