Span widths of self-supporting wooden frame ceiling

How to fasten it will be told to you by the structural engineer. However, as a layperson, I would now guess that it is fastened at the back with nail plates or similar.

You cannot generally specify a span, as it depends on the expected loads (green roof? snow?) and the dimensioning. Almost anything is possible with appropriate dimensioning. The question is whether you want to afford that much built-in wood and also whether you can still move the thick beams. Carrying the 20x12x500cm beam for the carport up the ladder was already quite borderline for three people.

As already mentioned, the calculation here does not go to a structural engineer or any other company. I also do not want any statement about the statics. I can handle the correct dimensioning myself, including the consideration of the corresponding point and surface loads.
My concern here is only how the optimal frame construction of the roof should / must look in such an implementation.
I would not be worrying about this if I basically had more support area. Unfortunately, this is not available, and therefore this question about the construction now arises.

Exactly that is a dimension from which I would make a frame at the top, but with 4x6m you won't get it up. The corner joints are force- and form-locked, as are the intermediate rafters.

So actually create the frame as a square and then raise it and accordingly dovetail? To be honest, I just can’t imagine it holding with only pure panels. The weight is relatively irrelevant. Machines are available to lift everything into place as well as support, etc.

As already mentioned, the calculation here is not going to a structural engineer or any other company. I also do not want any statement about the structural stability. I can handle the correct dimensioning including considering the respective point and surface loads myself.

My concern here is only how the optimal frame structure of the roof should / must look like in such an implementation. I wouldn’t be thinking about this if I generally had more bearing surface. Unfortunately, this is not available, and that is why this question about the construction is now coming up.

If you can do this correctly yourself, then why are you asking us here? Connection, construction, and dimensioning are not three independent variables but must be considered together. And that by someone who does such things professionally.

That is steel construction and then cladding.
