You still have the option of attaching whatever other device or gismo you wish to the concrete. Concrete is an adaptable medium like wood and steel, just requiring a slightly different bag of tricks. A piece of pt ply screwed to the concrete gives you a whole new platform from which to extend your creativity, a chainsaw sheath for instance, or whatever you please. A lot can be accomplished with tapcon screws, but if you need real strength, rent a big rotary hammer and throughbolt some angle.
