How sturdy is the frame

[Tovin]

I'm currently building an Attefall house. Right now, the frame is just finished. Everything feels sturdy, but I still feel like I should keep the braces that hold up the walls for a bit longer. After which step did you feel secure enough to remove them?


Then I have a question about the roof trusses. They are 45x220 in dimension. They are spaced at 60 cm center-to-center, and it's about 4.2 m between the back and front wall. According to the description, they should not need any additional support.
I'm just a bit worried about the weight of the roof tiles. Can they handle it, or would you have supported them in some other way?

I don't see a standing hammarband in your picture, I would have wanted that if not all the roof beams have a standing wall stud under them.
2x10" on 4.2m with 0.6m cc surely holds for roof tiles.
It will become sturdier when you batten the roof and put boards or nail strips on the walls if you want extra stability you first put perforated metal straps diagonally on the surfaces you want to stiffen.

With panels on the inside of the walls, the construction becomes stable. You must of course have a frame construction in the upper triangle on the gables. The span for the roof beams is on the long side for that dimension if you want insulation in the outer roof. I would have suggested c/c 400 mm. You can increase the roof's rigidity now by screw-gluing panels on the top or underside.

I have only reinforced with standing hammarband over the area where windows and doors will be. The studs are more or less aligned with each truss.

I will add studs in the triangles.

Why not a standing hammarband, it distributes the load nicely.

Because it didn't happen and now I don't have the energy to do it again

If you don't feel like fitting a standing plank as a wall plate, you can opt for the model of having the wall plate outside the wall studs, which requires significantly less work and can also be screwed on at this stage. It strengthens and stabilizes the framework. If you complement the walls and roof with properly tensioned diagonal perforated metal straps, you will get the house stable without using expensive sheet materials.

I was thinking of lining the inside of the house with OSB and plasterboard. Do you think it will still be necessary with vertical hammarband and diagonal hålband?

I was thinking of lining the inside of the house with OSB and drywall. Do you think it will still be necessary with vertical header beams and diagonal strap braces?

No.
I want a frame to be sturdy before I weatherproof it, then strap braces are the simplest and cheapest solution.
