Last night the roof trusses arrived... I was really surprised at how large they were... I had only seen them in pictures...
10 meters long and 4 meters high frame trusses... 25 in total, which are to be placed on cc60 for a garage, I might add.
These should go up on the framework that is 4.40 high...
Hopefully, I can stand with the excavator with crane arm in the middle of the slab and lift them up one by one...
I plan to start from the gable and work my way across to the other side.
How do I attach them to the wall plate? I plan to screw from underneath straight up into the truss with something like 6x100 screws, maybe 2 screws at an angle at each end of the trusses...
I have read that many use angle brackets, but is this really necessary?
Then, of course, they must be braced... the first truss on the gable I thought I would attach with 2 long boards that I screw vertically on the outside of the frame and extend high enough to be screwed to the truss as well...
Then the next one lands on cc60 - close!
Since they are frame trusses, maybe one should build a floor in the space and extend as you assemble them so you can probably brace quite a bit in that space...
Otherwise, I'm not really sure about climbing up about 8 meters on the trusses to brace them...
Yeah, some tips would be great!

you order shipping and the lift on site,
you don't need to come to the very top to strive, maybe halfway up the upper frame on each side.
angle plate or bending strip trusses take on large loads.

Do you recommend ordering the lift from an external source when I have the roof trusses at home and an excavator with a crane arm that I intend to lift with?
Okay, it sounds good that you don't need to brace all the way up... the attic space is about 4.2 meters wide and 2.4 meters high... if I brace in that space up to about 2-2.2 meters or so, maybe that's enough?
Then it also requires that I build some sort of floor in the framework so you can walk there... but I have quite a bit of lumber...
So you do recommend angles anyway... like these? https://www.byggmax.se/spik-och-skr...plattor/vinkelbeslag-med-forstarkning-p234290
Hmm, 4 per roof truss would be 36:- x 25 pcs = 900 + screws probably another 500:-... but I should invest in this anyway?
What do you think about standing up 2 studs in the wall studs on the gable where you can also attach the first roof truss so it stands stable, it would be difficult to brace a single roof truss...
Thanks for the response, I appreciate being able to discuss questions with people more knowledgeable than myself

mostly to avoid having to lift yourself, nicer to lift with a truck telescopic.
never work alone when you have to lift stuff.
sometimes it has happened that one has placed planks on the underframe and stood with a ladder to brace at the top when all rafters are in place.
have worked with angles without reinforcement.

Thanks for the input!
So it's going to be angles, but they don't need to be reinforced?
And is it nails or screws for these that are appropriate? Like 8-10 per angle maybe?
I will get help when they go up, so I definitely won't be doing it all by myself...
Good idea to lay flooring in the lower frame with some plank pieces... It doesn't have to be the thickest, considering the rafters are on cc60. From there, you can then go higher up and brace in the upper parts when all the rafters are in place...
Planning in the head makes you dizzy
I'll probably have to extend the crane arm by about 1 meter to reach up with a margin. But the rafters only weigh 120 kg each, so it's no big deal

goes faster with a spik. would use skruv every time.
just be careful. 120kg roof truss can do a lot of damage

Absolutely... It's the height that's the worst.. But I'm always careful!
I was thinking of building scaffolding with the timber until it's time to lay the roof, but do you think there would be any use for it already when the roof trusses are going up?
It feels like the only thing you do out by the top plate is just fasten the angles... But it should work just as well from a ladder...

it's always more comfortable working from scaffolding.
going to bring my assistant home one day for planning... then we'll see what he thinks... neither of us are carpenters but we usually figure out most things
but are angles 70x70x55 and 2.5mm thick without reinforcement sufficient
they were available at biltema for 5:- each, hot-dip galvanized. should you use one on each side of the truss, i.e., 4 per truss?
the truss supplier thought it was enough with 1 on each end of the truss on the opposite side, and that it was better than toe-nailing

My rafters were secured by the carpenters with an angle on each side. They placed the angles on the wall plate first, then the placement of the rafters went much faster since the positioning on the wall plate was already fixed. No measurement at the bottom was needed since the angles indicated the exact placement. The first rafter was secured with braces from the slab, but this might be an issue for you with your ceiling height and 0.6 m between your rafters; my rafters are spaced 1.2 m apart. However, if you secure the first rafter properly, locking the others is easy as they are attached to the first rafter.
since my roof trusses are quite large, it certainly wouldn't hurt to use 2 per side, i.e., 4 per truss...
I should be able to place them like you did, so the measurement is already done, and then when you get the truss there, you can fasten one on the other side as well...
thanks for the reply!
anyone else have tips and ideas? gratefully received!
sometimes it's like you've overlooked certain things that could have helped a lot afterwards!

Also be careful to measure them when you fix them so they do not become skewed at an angle. Also measure the walls/framework so they can move when you push around the trusses up there.
