Anchoring Pergola to Floating Deck
by Brian Laverdiere
I'm in the process of putting together a floating deck about a foot off the ground as seen at www.deckplans.com (Editor's note: deckplans.com is no longer an active site).
At that site, they are adamant about not recommending attaching a pergola to the floating deck. They recommend poured footings for the pergola and build the floating deck around it - keeping them separate.
This late realized bit of advice spoils the simplicity of my whole plan. Searching for alternate advice has lead me to this site. The Titan Post Anchor seems to be a confident bracket to use. Here are my questions:
Is it sufficient to attach the Titan Post Anchor to deck boards with screws - if so would it be better to drill holes and use bolts, maybe with a back plate instead?
Instead of the above, what if I place the Titan Post Anchor above a joist (or support board between joists) and use "U" bolts or a double plate/long bolt setup, so the posts are actually anchored to the joist instead of just the planks.
Minnesota can get some pretty strong winds, so I thought it would be a good idea to use the auger type tie downs on the deck itself.
If I used the Titan to joist method in the above paragraph, what if the place I pick for the tie-downs are the long brackets securing the Titan anchors to the joists. That way the tie downs are doing double duty - they strap the posts to the ground along with the deck itself.
I guess I'm a bit paranoid from things I've read and want to make sure the next big storm doesn't rip the pergola from the deck or send the whole assembly tumbling across the yard.
