Hi I'm putting a new floor level in an old concrete block building. I
am intending to hilti bolt a 3 x 6 wooden beam on opposing walls then
using joist hangers on them joisting across ( 14ft 1in span, 18inch
spacing ) with 6x2 joists.
Any suggestions on dimensions and spacing of the hilti bolts, also am
going to double up joists where bath& *water cylinder etc will be; is
it normal to have double width hangers for this or just bolt together
timbers?
I'm stuck with max 6in depth of joists as stuck for internal room
height.

First question - have you asked your building inspector (BCO)?

Second question - any reason for 6x2 rather than 6x3's? Just curious...

Hung parliament? Rather have a hanged parliament.

Thanks for your reply, I'm doing this in SW Ireland where building
inspectors are not as in uk, if at all !
6x3s would seem good, would I still need to double up at bath etc
positions?
