Did I do wrong?

[Hallerudsbo]

Tie-beams don't do much good when the rafters are positioned directly over the vertical studs.

Protte

unless there are large doors or windows, though.
But then you can recess a bearing beam there.

Excuse my ignorance, I thought hammarband was an extra plank/beam that lay at the very top under the roof beams and on the upper beam on the wall

 

[rattato]

No need to apologize to me.
I'm just glad people are responding.
I interpret it as people think the structure of the framework is correct. That makes me happy.
It is basically copied from those Attefall frameworks you can buy. Except the walls' dimensions and height have been increased.
And the area doubled.

But now as I add the roof, does the framework become more or less wind-sensitive? Do I need to brace more to prevent the walls from moving?

 

[Bronken]

Some more temporary diagonals (45x95 or similar) on the inside or outside of the walls - depending on which side you do (not) want to start working on first - are good and will calm you during windy conditions.
Diagonals from the bottom corners upwards tend to be stable.
Use the spirit level because it will be difficult to adjust the frame straight later when you want to put up the boards.

 

[Kallebo]

I did the opposite and skipped the hammarband, notched out and recessed in a support beam. The advantage I saw was that I could attach the roof joists with straight nail plates directly into each joist.

Great to see more people daring to take on similar constructions without much experience!
I think it looks stable. As mentioned before, the boards and roof will brace it further. When I built our garage, running on the roof and laying the boarding felt very flimsy, but with OSB and plaster, it doesn't move even when it's windy.

The task of the hammarband is to stabilize the wall and prevent it from being pushed outward by the load on the rafters. Therefore, it should be installed horizontally.

Should the ceiling follow the Roof rules, meaning you're allowed a maximum of 220mm insulation? That sounds a bit inadequate if that's the case. I had difficulty achieving approved U-values with less than 400mm when I designed our extension. (Or is it a holiday home, then I believe the requirements are significantly lower).

 

[rattato]

The ceiling is lowered, so it becomes more than 220mm.
But it is a holiday home though.

Hi!
I'm building an extension of 50 sqm.
Had a plan that felt right and stable.
But now that I've erected the framework, and see the reality and felt the weight and height, the worry came that I might have made some fatal construction error.
So before I continue, I'm asking the question here.

The conditions for the framework are as follows:
11.8m x 4.44m all lumber in 45x220.
Sill anchored in a pillar with an m10 rod, embedded.
Pillar every meter.
Cc60 on everything (floor, wall, roof)
In the sill, there are two beams laid with overlapping joints. Then wall sections.
The walls are 3.1m and 3.5m
Then roof beams on them.
Everything is screwed with 6x120.
Now I'm going to cross-brace with perforated tape to achieve rigidity.
Does this feel right?
Have I made any really gross mistakes regarding safety?[image][image][image][image][image]

Yes, I don't know if it's right but I've been taught that if there's a screw hole, there should be an anchor screw.

 

[Nissens]

Well, I don't know if it's right, but I've been taught that if there's a screw hole, an anchor screw should be placed there.

Well, not in all screw holes...

 

[rattato]

Yes, I don't know if it's right, but I have been taught that if there is a screw hole, an anchor screw should go there.

Are you thinking about joist hangers?
Yes, of course, they weren't screwed at all in the picture. However, it won't be in every hole.

What does your KA say?

 

[Michel1]

What does your KA say?

 

[Hallerudsbo]

Don't need to have KA on everything.
My construction that I did now, I was able to manage everything myself.
Then when I am finished, I will inform the municipality, so he arranged a paper for self-inspection.
When I submitted that, they would give me the final notification.

Building a combined stable with a garage now, about 100 sqm.

I also thought it was called hammarband...it will be interesting to see their answer. They might be thinking about avväxling under hammarbandet

The horizontal one is called hammarband. The vertical one is called standing hammarband, it transfers loads from the roof over doors and windows.
