Garage Loft Support

Earlier this month I noticed the 4×4 post near the center of the loft was bowed in two directions. Could there really be that much weight up there? As you may remember, we built the loft back in October. So here we are in May, five months later and now the post is bowing.

I was worried the whole thing would come down, so I had a friend come over and help me unload some bins I had stored on the loft. We installed a temporary 4×4 to help support the bowed post.

This past weekend I was able to run up to Lowe’s and drop about $50-$75 on some lumber, brackets and construction adhesive. The plan I made was to install two wing walls at each end of the loft. Each would provide 24″ of support under the LVL header. These wing walls will basically disappear once I complete all of my wood shelves I want to build along the perimeter of the garage. The primary part of my plan though would be two 4×4 supports in the middle of the loft. These two posts would be 3′ apart, leaving 9′ of open span to each side to the next 4×4 post against each wall.

I built the 2×4 wing walls on my saw horses and installed them. Under the bottom plates I used construction adhesive, then secured the plates with concrete fastening screws. I screwed the wing walls to the existing 4×4 posts that support the loft where it meets the walls. And lastly I screwed the top plate to the underside of the LVL.

In the center of the loft area I placed a 3′ bottom plate on the cement and a top plate on the underside of the LVL. Between the plates I inserted two 4×4 posts. I secured everything to each other, using metal brackets to help reinforce the 4×4 to plate connection.

I don’t think these new supports will hinder access to a parked car. I can’t imagine the loft is going anywhere now.

What I really believe is the single 4×4 post just warped as it dried out. I don’t think there was any danger of the loft collapsing, but it was scary at first until I could really assess the situation and reinforce it.
