Post and beam attachment


I'm building a free standing deck next to a pool with 6x6 posts. I was referring to the link to the American Wood coucil I found in a couple of posts and had a couple question. Great site thanks in advance

FOund this posted BY GRB_IN_WA; great document
http://www.awc.org/Publications/DCA/DCA6/DCA6-09.pdf


Does it make a difference if the notch on the post holding the beam is pointing outward toward the rim joists or in toward the center of the deck? See picture 1. Should the other set of post and beams be notched toward the outside?


On the notched method would it not be better to have the notch in the middle of the post between the two beams?. So in the 2nd picture there would be a notch on both sides of the post.

I have always used the "Sandwich" method why is that no longer recommended?

On the cap type that would be and nice clean solution but I've on ly seen those for 4x4 posts do they make for 6x6?

Here are the answers I found out

1. Does not matter which side the notches are on the beam whichever is easier.

2. the method with the beams sandwiched around the post has all the weight ont he carriaige bolts

You've already got most all of the information that you need in the guide. I'd say you're on the right track.

Put a bead of caulking down each side of the notch where the beam sits, leave a small opening for any trapped water to exit. Install sticky window wrap on the whole beam top and the post joint, full length to help protect from water. Treat the post and notch with water-proofing as p.t. wood is not. Lay a continuous caulk bead along the drip edge of the house ledger at the bottom outside edge to keep water from blowing back. Fill just each end of the bolt hole with caulking after the bolt/washer is installed, before the washer/nut. Use a deck cleaner and sealer/stain right away, if p.t. wood. http://www.thompsonswaterseal.com/advice/faq.cfm

Be safe, Gary
