Halve the intermediate beams

There are no clear rules for this concerning kortlingar, but the guidelines available are on how one can account for the lateral load distribution of "panels."

The problem with noggings is that it's almost impossible to place them perfectly. Noggings combined with screws and glued chipboard, I believe, contribute very little. However, one could use a stiffer board material, such as 21 mm birch plywood with 15 layers (I think). Then you can also attach a screwed plywood board on the underside. But it becomes tricky, as my carpenter from Blekinge always said when he didn't want to do something...

I thought krabbigt was Småländska. It seems to be spreading, it works for most things.

I myself have known it from Blekinge for a man's age and well so. According to Wikipedia, the practice is concentrated in the coastal areas in the southeast. It is said to have a marine background. But it is a very useful word.

In Malmö, it is used to describe someone who is muscular.

As Justus says, noggings don't do as much compared to a screwed and glued board, I think, with regards to load distribution.

The screwed and glued board provides both increased stiffness and increased load distribution, while noggings only provide increased load distribution. Increased load distribution can help against deflection, but it doesn't solve the problem of the structure being too weak for distributed load regardless.
