floor on uneven framework

[ALG]

I have some problems with my floor. I live in an old house and am going to build a new floor on the existing framework. The problem is that it's not framed at cc 60 but rather between 60 and 70, it varies. I was thinking of using floor chipboard first but it becomes tricky considering the joists. Can one use regular tongue and groove wood like 22mm and then lay laminate flooring on top or something similar? Grateful for any tips!

There are floor chipboards that manage not to be joined at a joist...
Double-tongued floor chipboard...

Fixed a spacing error

Another way is to add a new rule on either side of the current beam to get under 600mm in c/c spacing and use regular golvspånskivor.

PS MrZ's mentioned golvspånskiva is available at http://www.byggelit.se/compactfloor~48.php

Common floor chipboards should not be joined on beams, so it should probably be no problem. 60 or 70 doesn't matter.
