Might the "up" be giving you trouble? It frequently complements a verb, usually underscoring an idea of completion. Sometimes, of course, it confers quite a different meaning from that of the original verb --
Completion: "Finish" / "finish up". The sense of "done and dusted" is stronger with the "up".
Joan, redd up the parlour, I expect company this afternoon.
Different meaning: "Give" / "give up".
In the sentence that you cite "up" does not alter the meaning of "frame".
