Started garage wobbles

[abiz]

Bracing with metal bands rarely works well. They slacken in the summer when it's warm.

What is missing is:
-Sheathing boards on the walls. Wind barrier fabric is rubbish that is only good for wrapping up the manufacturer in when you've killed him and need to dispose of the body.
-Braces on the walls, especially the back wall
-Braces in the mid-roof
-Braces to prevent the rafters from tipping over.

There’s no need for construction drawings. It's about common sense.

Unfortunately, the wind barrier fabric is already in place so it will remain 🙂
Started installing metal straps yesterday but there was such a terrible thunderstorm, so I went inside. But I plan to put it on all the walls except the door side.
What do you mean by braces in the mid-roof?
I've actually been considering braces on the rafters. Can you just throw up some battens between them as high up as you're willing to climb?

By the way, for those who mentioned that everything is probably crooked now, I can inform you that everything is just as straight as when I put up the framework 😄

There is a recessed beam of 170mm on the outside of the wall plate. It was the supplier who recommended this because the trusses did not land exactly on the wall studs.

The recessed "beam" I call the wall plate. 😉 On the shed I’m building with a pent roof.

But it is a recessed bärlina and not a hammarband.

Yes, I just call it the same thing the municipality did, if it's right I don't know haha

Well, a sports hall in my county suddenly collapsed one winter day because the builder ignored the braces that prevented the roof trusses from tipping, relying on the roof board to hold them together. Pure luck that no one was there at the time, many could have died. A large hall that turned into kindling.

But should I just climb up and put some braces between all the roof trusses?

But it's a recessed support beam and not a wall plate.

It's probably a generational question, based on how they built in the past and maybe geographically as well 😉

"In modern building techniques, wall plate means the top horizontal rail that holds together a (usually wooden or steel frame) stud frame."

"In modern house construction technology, hammarband means the topmost horizontal beam that holds together a (usually wood or steel frame) stud frame."

Exactly!

Hey, I'm in the middle of building a double garage. When I went up to lay the roof decking, I noticed that the whole frame was wobbling. Is this normal?
Even now, with all the roof decking on, it still wobbles a bit. Will this fix itself with the siding or when there is a bit more weight from the roof tiles?

I'm a bit worried that I've missed something that I should have installed, haha. I'm attaching some pictures so you can see how the frame is built.

Furthermore, I think that the roof decking doesn't necessarily need to go all the way up to the ridge. The little gap of about 5-7cm that I have now can be covered with roof felt. Then I'll put on ridge caps, a ridge board, and ridge insulation over that, so it seems unnecessary to spend time making it perfect there. What do you think?

Edit: I assume the sill insulation, which is about 1 cm of foam rubber, could make it a bit more wobbly?

As long as you haven't clad the walls or installed diagonal braces, the garage will be wobbly. The simplest solution is to just take some planks and temporarily attach them at a 45-degree angle on the outside of the vertical wall studs, then remove these when you clad the walls. If you are going to clad with paneling on the outside, you should use wide boards on the inside to maintain the stability of the garage.

Oh okay, so it's just something temporary?
Shouldn't the facade have the same effect when it's on? But absolutely, I will do that until the facade is on.

Braces should be installed permanently on all walls. The facade contributes marginally to the stability, and it is not the facade's task to keep the building upright.

It is definitely not needed if you have records on the wall. Diagonal braces are often temporarily installed during construction.

Well, a sports hall in my county suddenly collapsed one winter day because the builder ignored braces that prevented the rafters from tipping, relying instead on the nail plate to hold them together. Pure luck that no one was there at the time, many could have died. A large hall that turned into firewood.

But that sounds like a fundamental design flaw.........A sports hall sounds a bit bigger than a small residential garage.

Yes, I know there are many here on the forum who think that diagonal braces are unnecessary. I am of the opinion that the frame should be stable even without wall cladding.

The problem is the same, the risk that the roof trusses collapse when the wind comes from the "wrong" direction, preferably together with a substantial snow load.

In this case, it was determined that there was no other stabilization than the metal sheets, and after several decades, the screw holes in the sheets were worn out due to excessive movement in the roof trusses, causing everything to give way and fall.

What's your point, by the way? Is it okay to build garages with loose roof trusses without any other stabilization than the tongue and groove? Even my garage from 1940 or so, measuring 5.5*3 meters, has diagonal braces between the roof trusses.
