new deck help
I am going to put a deck on the back of my house. I am wondering what is
the best way to attach the ledger board to the cement block foundation? Also, the deck will be 12 feet long and 8 feet out from the house. I am thinking of using the cardboard tubes (filled with cement) for the footings. The footings would be 6 feet out from the house and 6 feet apart for the 12 foot length. I would be using 2" x 8" (doubled) treated lumber for the perimeter. In the future I would like to make this into a screened-in porch. Would this be o.k.? Any HELPFUL comments or suggestions would be greatly appreciated! Thanks in advance. |

I am considering a similar construction this fall or next spring. Talk to your building inspector about how to attach to the foundation, the answers you get here may not pass code there. The connection of the ledger board is probably the most critical part of building a deck. Based on an 8' span and 6' between columns you should be using at least double 2x10s for your beam. If height is not an issue, oversize your beam and floor joists. A friend of mine went within specs for a 9' span (2x6 is allowed) and has bounce. Also if you have the clearance it is a lot easier and cheaper (no joist hangers needed) if you set the joists on top of your outer beam. You should not need doubled joists at the ends (perpindicular to house) only for the beam (parallel to house). Again, talk to the inspector. Here are some helpful links: http://www.startremodeling.com/decktables.htm http://www.awc.org/calculators/span/...eversecalc.asp http://www.awc.org/calculators/span/...rcalcstyle.asp |

Another thought or two: If you are able to set your floor joists on top of your beam you could move your footings closer to the house and closer together. You might be able to have the footings 5' apart and 6' from the house. This would mean that your joist would overhang 2' and your beam would overhang your footings a foot on either end. But of course if your height requires you to have the joists hung at the same height as the beam this can't be done. |

Thanks in advance. contacting your building department is good advice. in my town, they have the requirements for decks on their website. if you are adding a porch roof, you are adding load to your foundation. it depends on what your snow load is, but where i live you would basically have to double the footings. you can put a foot on your posts, or add more or something similar. |

Best way to attach ledger to block would be to use carriage bolts through to the inside with large washers or steel plate on the inside. I never have any luck with anchors in block. As others have said, your building dept will likely have guidelines. Inviato da X-Privat.Org - Registrazione gratuita http://www.x-privat.org/join.php |

It wouldn't be that much additional work to put a few footings and posts
near the house thus putting the weignt on the posts and using the ledger for stability rather than support. JD "RayV" wrote in message oups.com...
