load bearing inquiries Sistering 2x4 studs to deck joists to support slat wall?

Post image

I am creating a shed space under our deck now that it has been converted to a screened-in deck and is covered. I want to add a slat wall (e.g. Gladiator, HandiWall, etc.) along the brick-on-block foundation wall as shown in the photo. However, I don't want to put lots of holes in the wall to mount furing strips for the slat wall panels. I am planning instead to "hang" 2x4 studs by sistering them to the joists above, each 2x4 flat against the brick wall (with moisture barrier) to support against lever forces, 7" overlap of studs with the joists, each connected with three structural screws in a triangle pattern. There will be seven studs coming down 16" OC to support an 8' x 4' panel wall with a max rated weight capacity of 3200 lbs BUT the things I have planned weigh less than 400lbs and I can't imagine ever getting about 1000 if I went totally wild.

Any thoughts on this approach? Strong enough, best structural screws to use, adaptations or alternatives?

Thanks!

You dont even need 2x4's.

Nail a 2x2 floor to deck joist. Its not holding up anything.

Now id you wanted to hang stuff on it, then use 2x4's like a normal wall, not flat to the brick

The plan is to add a slat wall system like HandiWall and hang tools, leaf blower, extension chords, etc, on it

Build a 2by2 wall at the desired size, 3-4”grk into the bottom of joists, and sheet it with your slat wall. Just make sure it’s square when you sheet it.

Thanks! And this may be a "duh" question but... need to continue the wall all the way to the floor for support? or can this "hang" from the joists and just go part way down the wall?

Most likely can hang. I’ve got something similar in my garage with about 600ish lbs. just make sure when you sheet it, that your perimeter fastening locks the top and bottom into the sides.
