Studwork puzzle

[daggermark]

I've noticed that none of the upstairs internal stud walls in my house have the top plate fixed to the ceiling joists. In fact, there is a good 20mm clearance between the top plates and the underside of the joists. Would anyone like to hazard a guess as to why it has been built this way?

My guess is that the joists were put in first with plenty of clearance to the first floor, and then they had to make the studwork shorter to accommodate 2400mm sheets of plasterboard. It doesn't make for the sturdiest construction though!

A guess would be they forgot to fix them. Or the studs were all cut short.
You'd notice the gap if the pb didn't reach the ceiling...

Maybe I haven't described it very well. The walls are 2400mm tall, but then above the wall top plate is a ~20mm clearance to the joists. I wondered if they set the joists too high in the first place. Although I'd have expected them to put some scrap in the 20mm gap and nail thru, just wondered if there's any good reason for not doing so.

nothing wrong with the gap -perfectly normal

everything wrong with the fact it was not packed and then the top plate fixed


joists wouldve gone in first -they are probably set on the wall plate

As I suspected. Thanks.

They built the stud framing on the deck then raised it. The floors and ceiling would have been in place.
