Subfloor repair help

I had a couple weak spots in the subfloor so I cut them out. I’m unsure how to brace the wood between the I beams? I was originally going to creat a box out of 2x4’s but I’m not sure if I can attach it to the OSB I beams. I expected solid wood joist but I have these new I beams in my house. submitted by /u/The___Thumbs [link] [comments]
