Put a nice 4 bolt flange on the bottom and beam pocket on top and that thing would make life easy.

Hang a HU or a HUCQ off the post, that would also help tie the whole assembly together.

I agree, I was just wondering what his method would be. Wanted to see if he was intending on nothing.

Please exchange "nothing" for "notching". Damn auto correct!

Re: How To Attach Deck Roof Support Posts


In the mid-atlantic region the 20' posts that I had run across were pretty crappy and twisting was a concern whereas I've had good luck with the 6x6 cedar in Texas.

Are there laminate post options for you guys around the country? What are some of the more stable, long length posts options?

Re: How To Attach Deck Roof Support Posts


A Man can use pt timbers, like 6x6'', as long as they are covered up in a timely nature.

20 footers would just be asking for trouble. I would build that thing, if I am visualizing correctly, like I would a house.

Starting with the deck . Square it up I usually put the perimeter up in a temporary nature, place the piers including the ones for the second story ( roof ) if the corners of the deck are the same as the roof the same piers used for the deck as the roof. Bolt down the steel U shaped brackets with anchors or two part Hilti. to the pier ( this is how Mike does it .. I land the brackets on the decking just to save time ) Bolt the 8' ( or whatever high they need to be ) posts to the brackets.

Then build the second story, Roof , landing your beams on top of the posts secured by regular post brackets. As soon as possible wrap all the posts with 3/4'' material. Special care taken with the 1/2'' steel brackets as they will have to be bigger than the post wrap which is ok cause most of the time the bottom of a post like that looks better bigger anywho.

Build the rest as is normally done. A lot of info you might not need or want. The main thing as I see it was the support for the posts. That heavy duty steel bracket will solve that issue with change to spare. No lift, No sway, and No wiggle. Any decent fabricator will square those brackets up and weld both sides but be sure you allow space for the always inconsistent measurements of pt lumber. 6x6'' could mean 5 3/4 '' or any variation of that, I have seen 6 1/4'' on what was supposed to be 5 1/2''.

Anyway good show with the Marines . The military is tough to go in and stay in , getting out is not all that easy either so good fortune to Ya.

Yes, the plan was to notch the 6 x 6 post to support the deck beam.

Then run the rest up to support the cover? That's a pretty flimsy "taint" left on the post after the notch.

Re: How To Attach Deck Roof Support Posts


Just make sure the footers are up to snuff. I'd overdo it here as I've seen many a failure on these types of jobs.

With a deck and a roof you got a hell of a lot more point load than you think on those 6x6.

no store bought bagged conc...If you must beef it up with some portland and some real aggregate and don't forget the #5 or #6 bar

Given all the problems with wood posts warping, and the pain of installation, And questionability of continuing the post from the photo to the roof, I think I'm leaning more towards supporting the deck beam with steel posts, then using 4 x 4's set on the deck beam to support the roof.

sounds like a good plan, hopefully when you say 4x4's set on the deck beam, you will use more than toe nails to attach, maybe some straps as shown earlier in the thread

and will be "over" doing the foundation

Re: How To Attach Deck Roof Support Posts


Specify "Free of Heart Centre" post material and they will check/twist/warp less.
But you need to find a good Sawyer to cut them special for you.
And the special nature of them will reflect in the price, of course.

Re: How To Attach Deck Roof Support Posts


he can support it with telephone poles, I'm more concerned with what's underneath of it.

Lot's of so called deck builders run around here putting up stuff like this and use 12" sonotube and that $4 a bag concrete...which is nothing but a pinch of cement, some fly ash, and pea gravel

Last one I did was supported by 2 P2 Techno Metal posts. It takes a lot of digging and concrete to match what those things are rated for.

I'm bidding on a job right now with telephone poles. ScipioAfricanis ( Andy ) is designing it.

I would use post brackets for the 6x6 and put the 4x4 inside the double bands blocked or bolted.

Re: How To Attach Deck Roof Support Posts


Most likely needs an engineer or architect to design. Of course, there are some places in this country where anything goes. Call the city up and see if you will need a signed and sealed set of plans first. If so, trying to figure it out on your own may just be a waste of time.

Re: How To Attach Deck Roof Support Posts


Putting a 6X6 20 footer SYP PT wet post up solo is no picnic, but it can be done. If it's KD, it's much easier.

What you use really depends on what you can reasonably get. Theoretically, you should be able to get some really good 6X6s in Georgia.
