Looking for advice on attaching the vertical columns that hold up my deck to the horizontal beam that runs across under the joists.
12'x 16' deck, 7' off the ground. At the end away from the house, there are (3) 4x6 posts holding up the support beam under the joists. The beam is (3) 2x12's nailed together.Right now, the beam sits in a 4.5" notch cut into the 6" dimension of each post. The remaining 1" piece of the post is nailed to the side of the beam. This seems like a weak way to attach the posts to the beam. Also, there are no cross braces between the three posts and I think there should be. I need to redo the footings for other reasons, so I figure this is a good chance to add the "X" bracing between the posts and fix the attachment points.
What's the correct way to attach the posts to the beam ? (Cheap ascii line drawing follows)
