Fine glulam beam

[ordain]

I don't have a picture of mine, but it is 115x630 and about 19 meters long.
Actually so long that it is spliced at one point, but the longest piece is 13 meters.
Half is built-in, but the bottom part is visible.

Wow, do you have a picture?

After I went up and checked today, I realized that the beam didn't go as far along the ceiling as it looked in some pictures with a strange perspective; it's probably only 8 meters long or so, not 11.

Exactly!

But, it's not just nice in the attic, the ends are also laid on support walls resting on the foundation wall - thereafter, all the trusses' bottom chords are anchored to the glulam beam with double angle brackets and seven million anchor screws. Instead of having the beam underneath with the load resting on top, the load instead hangs underneath. About 6m of wall was thrown into the trash, so just to be safe, we "tossed" up a small beam.

Ok, thank you for the answer. How do you calculate how much it supports? Is it as much as if it were under the timber joist, it shouldn't be. It's a smooth and nice solution as you avoid lowering the ceiling by 40 cm.

"Where are the brides?" Can't this thread be renamed to "The Male Thread" and then we can pile on with oversized and overpriced gadgets/construction materials?

Damn, if I had more klampar, I would have fixed such a beam!

Ok, Thanks for the answer. How do you calculate how much it supports? Is it the same amount as if it were under the wooden floor structure? It shouldn't be. It's a convenient and stylish solution as it avoids lowering the ceiling by 40 cm.

The calculation was done by the glulam supplier. In terms of dimensioning, it should carry the same load regardless of whether it is on top of or under the floor structure. The beam is probably significantly over-dimensioned.

How lucky you are to just be able to go and buy. I had to make my 8 myself. 11.8mx270x95 We put them up ourselves, my daughter and I.

And how nice it is for YOU to have so much time that you can make them yourself.

 

[Mikael_L]

It IS manly with big things, definitely!!!! ;D

 

[saturnus]

And how lucky YOU are to have so much time so you can make them yourself.

Well, that's probably the case for many who lack the means, that they have to do it themselves

Saturnus:
What glue did you use?
Is the beam slightly bent, or is it an optical illusion in the picture?

It seems interesting to make glulam; when I built brick arches for the garage, I pondered for a long time on what edge I would make to close the swing door against at the top. At the bottom, I made a recess in the slab with an extra threshold iron... but the top was a tough nut to crack  

Then I came up with the brilliant idea of making a "glulam beam," still had the form from the masonry, sawed 5 strips of 10*50 mm, glued and screwed these strips with long screws + washers.

The day after, when I unscrewed the "beam," I tried standing on top of it; it barely changed shape at all, stable as hell

I almost have to agree with manberg ;D I thought grown-up guys had moved past the whole who has the biggest thing ;D But it's impressive with big beams, even more impressive when they are visible

It seems interesting to make laminated wood, when I built brick arches for the garage, I thought for a long time about what kind of edge to make to close the swing-gate against at the top; at the bottom, I had made a notch in the slab with an extra threshold iron........but the top edge was a tough nut to crack  

Then I came up with the brilliant idea to make a "laminated wood beam," I still had the mold from the masonry, sawed 5 ribs at 10*50 mm, glued and screwed these ribs with long screws + washers.

The next day when I unscrewed the "beam," I tried to stand on top of it, it barely changed shape at all, rock solid  

Yes, an accurate observation, I wanted to eliminate any risks of the beams sagging under their own weight, so they ended up being prestressed, and it worked.
The glue was regular water-resistant wood glue, some from Biltema, which I believe is manufactured by Casco.

The construction is progressing http://img.photobucket.com/albums/v388/Z-Jensen/panel.jpg

I almost have to agree with manberg ;D I thought that grown men had outgrown the whole "who has the biggest" thing ;D But it's impressive with big beams, even more so when they're visible

Yeah, mine is so small that it's barely visible.........50*50 mm  :-[
