Anchors for 4x4 posts onto cement? Suggestions?

Once you tie the 4x4 "wall" to the main house, it will stabilize(be sure to tie the joists to the top of the wall by toe-nailing or using the brackets designed for this application similar material as the 4x4 brackets--if i'm thinking of the same thing). The anchors are only to keep the base from "kicking" out. As long as the bottom is secure to the pad, and the top will be tied to the house, it will be ok.
