My older deck doesn’t have a beam. Instead, the rim joist is attached to the 4x4 posts, most of which are notched and serve as both support for the rim joist and continue up as railing posts.
I noticed on one post, the rim joist ends on top of the post and abuts a second span of joist. It seems like there isn’t much of the joist actually sitting on the post and I was wondering what should be done to ensure the rim joist can’t pull away and fall off the post.
Both joists are currently nailed to the post and I just screwed two structural screws through the joists and post.
