It’s a joist bridge. You know, a bridge over a joist. đ Or would it be a post bridge, a bridge for a post…. Either way, we’re working on repairing part of the floor in the barn. Amongst many issues, the roof leaks. And has probably been leaking for the last 20-40 years. It’s on our todo list. đ But, the perpetual leaking has rotted out this joist, on which a timber rests. This timber(post) holds up the roof, basically. With there being a beam directly under this location of the joist, the solution was simple. Weld up a joist bridge. đ 1″ plate steel for the top with 2x4x1/4″ rectangle tube for the legs. It outa hold it for a while. đ
