bolts and length advice for lean to

[arcon5]

Using 6x2x 4.7m wall plate with joist hangers to carry 13 6x2 joists on a 9 degree slope. Landing on a 3x2 ring beam on top of conservatory.

What bolts is recommended... i understand on to brick it needs bolting every 400mm.. does that sound about right? I'm assuming coach bolts...

How deep in to the brick should the bolts go?

Thanks all

You want expanding fixings.
70mm Into brick. Try and avoid frogs/perfs.
Go 600mm c/c if it works with joist spacings.

Are this sort of thing suitable... rawlplugs...

 

[JohnD]

yes, but those are not rawlplugs

I might paint the screws before fixing to delay rust and staining
