Looking at the floor joists of our porch I noticed they are resting on a long board that is nailed horizontally into the band joist. The porch has to be at least 60 - 80 years old. I can't believe the board has supported these joist without separating from the sill all these years. I'm not a carpenter, but I can tell this isn't a good way to support a floor, even if it is just a porch floor. The joists span 9.5 feet. Pictures of the 3rd -
8th joists in this siteNeed to shore up the porch before putting in new posts. Thus, I need to support the outer band joist and this joists holding board at the same time. Was looking to use A-frame structures to catch the both beams/boards. However, I am just afraid the nails of this joist supporting board may come loose or crack if I don't do it right. Any way to replace or support this beam so it will have some more structural integrity?
