Thread: deck structure on slab

Howdy,
I have tried to search out my question, but had limited luck.
I'm building a deck and am fixing the structure directly onto a concrete slab.
My question is what is the best bracket to use to do so and what size dyna bolts would suffice.
Also how many brackets would I need along the 4.0m lengths?

Th decking will be 12.0m x 4.0m (approx) so I am having bearers fixed to the slab every 450mm (approx) across the 12.0m length.

Thanks,
Chris
