Building a free standing carport.?
Question:what is the best way to anchor 6x6 treated post on a 22x22 carport with a hip roof with 8/12 shingle roof system? can it be done without setting posts in concrete in hurricane zone?
Answers:
If it werent for that 8/12 all hipped roof I would lend some help besides the fact that it is free standing. That is going to be one crazy looking carport. Its going to look like a pavilion with a really large, bad hat on it. The only advice I'll give is to crossbrace between your 6x6 uprights and the lvl beams that will be necessary to hold this behemuth up.
you need to check with your local zoning office, they will answer this correctly. i would think that you could fasten a metal anchor to the concrete then attach the post to the anchor, but do check to make sure
yes, THEY have some anchors that can be drilled into the concrete.Don't know where you live in Georgia the post have to be setting on brackets or a way to keep them off the concrete.Might get some cables and some Mobile home Tye downs they seem like they might get you there.Got to secure them someway L brackets.
This thing is going to be huge! Of course you are going to need some concrete. How many posts are you setting? Four six by six posts will not support a building of that size. You would need huge beams, LBL probably, to make that span. In a hurricane zone, (I live in New Orleans), you can reduce the wind load by building an all hip roof. Why 8/12? This thing is going to be 18 feet tall, with a low ceiling height.
tie your *** to a tree
You can build this without setting your posts in concrete. I would double check with your code enforcement office about using drilled in anchors. My experience has been to use J or L anchors embedded into the columns/footings once poured. Depending on your zoning, your footing may need to be anchored to your column with some type of anchor, in addition to the anchor you use in your column for your base/stand-off plate. To additionally resist up-lift, I run 4 straps up my posts and over my LVL. 2 up the front and over, then two up the back and over, starting at least 8 inches down from the top of the post. I have also been required to use G8 bolts/lock nuts and plates to bind the posts/beams. It just depends on the zone requirements. I just strongly urge you to not drill your anchors, but to embed them into the column when you're pouring. Happy building.
