Is it solid concrete, i.e a poured concrete wall, or cinder blocks? If solid, or the cinder blocks are filled, you can use red-head expansion bolts to fix a pressure treated 2x4 to the wall, the another with 3ā screws and glue to come out the distance you need. If the cinder blocks are hollow you may be able to stick a 2x4 to it with a ton of pl500 and a few tapcons to hold it until the glue dries.
Edit. PL premium may be better

If you decide to use the expansion bolts Iād recommend renting the giant drill and concrete bit from Home Depot if you can. I installed a deck once and the rental drill made installing the bolts a breeze.

The "giant" drill LaoWai is recommending is a Hammer Drill. Get the appropriate sized masonry bit for the anchors you'll be using when you rent it.

Minor nitpick, it's a rotary hammer, not a hammer drill.
Rotary hammer uses a special sliding bit called a SDS bit that moves back and forth. Only the bit moves. It also has a mode where it can hammer without spinning and use chisel bits for demolition.
Hammer drill uses a normal masonry bit in an adjustable chuck and has a mechanism in it to vibrate the entire chuck back and forth
Rotary hammer is really what you want for anything beyond just doing a couple 1/8" holes. Having both, a rotary hammer can do a 1/2" hole in a granite boulder faster than a hammer drill can do a 5/32" hole in brick.
Both are colloquially called "hammer drills" but you've got to make sure it's actually a rotary hammer and uses a SDS bit.
