Setting out masonery joist hangers

[garyo]

I'm just about to set out a batch of hangers identical to those below. Although the bottoms are 45mm as required, they come out of the box on a slight splay meaning the tops are anywhere between 50 and 60mm.

Being so springy, closing them up to 45mm and getting them to stay there is easier said than done. Am I okay to use the smaller holes on the top with, say, 30mm nails to tac them at the right width prior to mortar going down?

Why aren’t you just building the joists into the blockwork?

That's what the holes are for.

Put a joist off-cut in them to set them

I'd convinced myself that hangers would be easier, plus modern standards to avoid gaps and drafts etc.

Also, my span is 4.74 so nicely suits a 4.8M joist. Building in I'd require 4.9M.

Thanks.

Having said that, last night I was wondering about going back to a ledger plate and using timber jiffy hangers but I'm not convinced the thermalites would take the through-bolts very well.

Can see the logic there, saves messing about with cut blocks
