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 Iā€™d 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.
