Scissor trusses over deck – point me in the right direction please
See image. We are owner-building something very similar to this picture. Maybe because I don’t know the correct terminology, I cannot seem to find any literature about how to tie in the beams that extend from the wall top plate out over the front porch to support the scissor trusses (i.e. How to frame and fasten/how far back into the wall the beams should extend/etc?). Can anyone offer more information please?
Details: One story house on post and beam foundation, 24×40′, 5/12 scissor trusses down entire 40′ length, plus scissor trusses to cover additional 8′ front porch. At the porch, we were only planning to run posts all the way to the ground at the very front truss, then possibly include intermediate posts (like they show on the left side of the picture) that only run to the floor of the deck. The deck joists (and therefore the intermediate posts) are supported by our 6×12 foundation beams. We live in one of the highest snow load areas possible, so don’t go easy on me when it comes to proper roof support.
