Those simple screws look incredibly not-strong to me.
Plastic anchors in the correct sized hole do pretty well at not being pulled out. They aren't something I'd use overhead for anything more than a construction paper kids project. But for what you're doing, I think they'll be more than sufficient.
Tapcons are probably as good or better than the other thing you had - the screw threads bite into the concrete, so for them to be pulled out, either the thread fails, or the concrete does. I have used tapcons for a small project (mounting safety sensor for garage door) and the only issue I had was drilling the holes (I think I hit a rock or something that didn't drill easily, but moving half-inch to the side gave me no problem - and now that I have a rotary hammer drill, I don't think I'd have a problem at all.)
Looking at the tension force on tapcons - it'd take a lot to pull them out of a cement wall:
My best thought to attach the vertical "bulkheads" to the strips is something like this: http://www.carinya.com.au/plugins/carinya/images/angle_brack.....
