I have a patio roof that is sagging in one corner due to a poorly constructed slab. I am going to install 4 concrete columns 2 ft in the ground and 2 ft above with a post support mounted in the form. I am going to replace the existing beam and relocate about 10 inches further away from the house. By moving the beam further it will be lower to the ground due to the pitch of the roof. I don't want anyone to hit their head so I need to think of away minimize or eliminate a beam over the walkway to the backyard.
Is it possible to have 2 seperate beams instead of one continuous beam? I want there to be enough clearance through the walkway.
The joists are 11' 9" with 22" spacing. The beam is 28' and is 4x6.
I would like to remove the middle section over the walkway which is 8' or use sandwiched 2x4 for a 4x4 beam. I am going to use 4x4 posts.
