Today I wanted to share with you all on how I framed the floor of my house. The framing was done with treated 2×4′s placed on 2 foot centers. The trick to framing is to have all your joists designed to both land on 24″ centers (so when you place sub flooring – 4 feet wide – you know exactly where to screw into the floor joists). The other thing you need to consider is the forces that the floor is going to be encountering, this effectively is your foundation, so it’s important for this to be really strong.
To add more strength I used corner braces that are used in hurricane prone area building, I also tied the floor joists to the deck of the trailer using high sheer strength screws. I screwed from below the trailer, through the trailer decking, into the joists. In certain key joints I chiseled out notches for the cross members to sit into, this wasn’t in the plans, but I thought the potential forces seemed to call for it. Here is a video and then a bunch of photos after that.
