Without pictures, I am not sure I understand quite what the problem is.
But - it sounds like the kind of thing I would solve with one of the threaded metal fasteners used in the furniture business, amongst others.
There is a T nut, an insert nut, or even a threaded cross dowel. Available in different lengths and threads, and will take a countersunk setscrew to fasten your floor to the frame underneath,
in a blind hole if you use the insert nut.
