I might have a bit of a problem....
I did fair bit of planning on the structure of my free standing deck (spans, beam size etc) and decided to settle on a deck plan in the back of a deck book. (at least I though I did enough dd)
It's a low lying deck (deck surface 10" above grade at the lowest point) ...so I am using 2x6 for most of the framing. The deck-book plan recommended attaching the (4x6) build up beam to the side of the post (which will be very short) attached with 1/2" x 7" carriage bolts for 2 reasons:
a. There is not enough space for the beam to sit on top of the post.
b. You can avoid the troubles of ensuring the footing + piers are at the exact height (which you would have to do it the beams sat directly on the footing).
so... I followed this advise and now have piers of approximate height and precast 4x4 metal brackets installed into the concrete.
As I am about the begin construction of the frame I have read (aka googled) that installing the beam this way is not recommended and that notching a 6x6 is preferred. Unfortunately I didn't go the j-bolt route and already set my 4x4 anchors into the wet conrete (which isn't wet anymore).
Is attachnig the 4xbeam to the side of the post with a couple of carriage bolts okay ? Notching the 4x4 say 1.5 inches will not be possible because part of the beam would have to be inside the 4x4 anchor (because the deck is so low).
Use a stubby little 4x4 "shim" to get the correct height and sit the post on top of that?
This could be a big negative for a combination of first time deck building AND not requiring an inspection of the plan/construction.
Any suggestion would be welcome.
