Hi
I am putting a new 1st floor in (4.3m span) and will be fixing 225 mm x 50 mm wall plates to the block wall with rawl bolts. I will then hang the joists (225 mm x 50 mm) from these with timber to timber joist hangers.
My question is, do the joists have to be perfectly in line with the wall plates or can they hang below slightly. Also what nails are recommended for fixing these and do you have to nail to the top of the wall plate as well as the face of it.
Any help will be a big help !!
