I am trying to understand how my house is constructed because I am preparing for a roof lift. The construction drawings I have describe a construction like this http://www.traguiden.se/TGtemplates/popup2spalt.aspx?id=4689&contextPage=5946 but what does it look like in the other direction? that is, along the floor joists. What are the wall studs standing on? It can't just be the edge beam ("3:an"), do you put an extra edge beam/floor beam so that the upper sill doesn't tip, or? I will need to reinforce the existing structure to support the new roof, so it may be good to know what it will stand on (BEFORE tearing into the old one).
It is impossible to know how they have done it.
There might be a similar "C" of sill-bearer-sill in the other direction with noggings in the last bay.
There might be double bearers and the floorboard extends out under the wall.
The wall might continue down past the joists directly to the foundation, i.e., with just a sill and the joists inside.
Or some combination...

There is no risk of the upper sill tilting with such a construction, it stands stable on the edge beam and floor joists. I have this type of construction on my 1 and 1/2 story house, and it works perfectly. Of course, the wall framework is anchored to the joists.
The floor joists are supported at regular intervals, and the number of supports and their construction depend on, among other things, the length (span) of the floor joists, their dimensions, and the type of foundation you have. See some examples here (if you have a crawl space foundation?):

Ok, thanks for the answers. It will simply be a surprise the day we start tearing it up. My thought (or rather my builder's thought) is to nail a 45*145 as a "T" onto the existing studs, but then it's good if there is something it can stand on. Hopefully, there is a wall behind the wall, it looks that way since they seem to lay the sill at the edge of the wall.
