more glulam

[saturnus]

so it was time again with 20 pieces of glulam, 13.5 meters long and 315X95. The wood holds K24. Some screws have been purchased at Biltema
6X180 mm = very high quality, probably the same steel as in reinforcing bars

Fancy.
Can you add some questions: what kind of glue do you have? How do you ensure the beams are straight? What will they weigh when finished?

May one place an order for a balk if the need arises?


I'm a little impressed, wasn't it you who made pre-stressed laminated wood beams earlier?

 

[saturnus]

Biltema's white wood glue, waterproof, works well. I've welded together 14 angles weighed on the pallets, which I pack the beams on, glue and nail together with the nail gun, and screw. Weight = about 200 kg. Yes, I have manufactured the same type for the garage before, but then I built them vertically and assembled them by hand with 5r. I have 50mm overlap on these, but there will be no sag, so the roof will be a bit humpy, but that way it looks fresh. Buying this number of beams ready-made would have been expensive, and transporting them would have been a problem. Thanks for the interest.

Interesting that!

I need a glulam beam for a carport, I've calculated that it should be 66x450 and 7m long.

Could you stack 10 pieces of 45x70 on top of each other and how would that compare to a 'fine beam'?

As long as you know what you're doing, it works. If you've calculated using some online program, I suggest you increase the dimension a bit. If you only have 2 supports over 7 meters, it places requirements on the beam, boring if it starts to sag a bit after a year. Go up to 95X450 to be on the safe side.

It would likely not match the quality of a "fine beam" unless you have a handle on the wood quality (C30 in the outer lamellae and C18 in the inner lamellae on an L40-beam), its moisture content, finger jointing, glue type, glue amount, press pressure, and press time. There's a bit more to it than just putting sticks together.

 

[saturnus]

haha, sticks.......... We call 45X95 for reglar. But if you're suspicious, you absolutely shouldn't make your own. Personally, I think there's too much give in store-bought ones.
Here are my previous glue-laminated beams = model "pro"

 

[injonil]

Yes, probably best to go up in dimension as you say Saturnus. I'll read a bit in your original posts about custom laminated beams before I get started...

Beautiful work! Lovely color combinations and nice finish!

Thank you injonil, I hear you have good taste
