Joint in ceiling joists for additional bedroom

Post by ikneweskimo » Mon Oct 03, 2022 5:03 pm

Hi,

I'm planning to rearrange the walls in my 2 bed semi to allow for another bedroom. To do this effectively I need to move a stud wall that runs across the roof joists, by about 300mm. I've been up in the loft and there's a joint in the roof joists that sits on the stud wall. When i move the wall, that joint isn't going to be supported by it any more.

Im wondering if I can fit some bolts through the joists where they over lap, and then fit some timbers running across them like a strong back to tie them all together (maybe board over them all then for storage in the loft) there's a couple of timbers running that way already under neath the pearlings. would this be sufficient?

They're only 3x2 timbers and i don't think they really hold much weight do they? Aren't they more to stop the roof spreading and for the ceiling to be fixed to?

The stud wall doesn't sit directly on top of the brick wall below so I don't think it's Purley structural...

Advice would be greatly appreciated

Hi ikneweskimo,
If the joists overlap by a good length - at least 600mm you may be ok doing your bolting proposal but you will need 4 bolts per overlap. Do use 50mm square plate washers under the head and nut of each bolt.
You could employ a structural engineer to check your proposal but I suspect you will be told to fit larger joists.
Regards S
