« Part 8: The Inevitible Push Block Part 9 of Virtual Designs in Sketchup series Part 10: TS Blade Holder »

I’m installing a wood rack I built and would appreciate any input as to mounting. This is going in a dingy basement. In fact, it is going in the only room remaining that still has a dirt floor. The rack has been built and consists of 4 vertical supports as follows:

The room where it is going looks something like this:

The rack will be mounted on the right-hand wall like this:

The vertical pieces will be supported by a simple 2×4 lying flat on the floor. Verticals will be toe-nailed to it, or more likely screwed to it(toe-nail style). The upper ends will sit flat against the joist by the wall. My question has to with fastening the upper part securely. I’m considering a simple 2×4 block(shown in gold) with the center cut out and installed as follows:

I will be screwing into the left end of the block through the left-hand joist and toe-nailing it on the right end to that first joist. Connection will be entirely with the joists. No connection to the flooring above. Would you consider this sufficient or is more blocking needed? I’ve calculated a maximum load of about 150 lbs on each support. That is the maximum. I doubt they’ll get more than 100 in actuallity.

Suggestions, comments?

Those should work just fine! In fact, more than fine. At the top of a wood rack, it’s all pull out force, very little down force on the fasteners as the weight is supported by the floor. So what you are doing is pinning the upright against the joist and using the adjacent joist to keep the top from tipping away from the wall.

The only thing that worries me is the dirt floor. If it shifts of compresses, then all your weight is hanging from your fasteners. You might consider using a concrete block or post pier buried in the floor beneath each vertical post to help carry the load.

I have a similar situation in my basement except it’s a concrete floor and I am supporting shelf units. I have had over 2000 lbs. of stuff on those shelves and nothing has budged.

Thanks for the input Tim. Maybe I’ll use 2×6’s and toe-nail into the other joist and the verticals can just float. This is sort of a short term solution. The long term solution is to move. :)

I’d use a couple of 5/16 lags with fender washers to connect the verticals to the joist behind them or use countersunk Tapcon screws through the vertical and into the brick wall below the joist and about 1/3 of the way down.
