A corner joint tie includes first and second forward plates connected along a common vertical edge and oriented at an angle of less than 180°with respect to one another. A pair of first and second rearward plates are connected together at the same angle as the forward plates, and spaced rearwardly from the respective first and second forward plates by first and second straps. A rib is affixed along the length of each rearward plate to strengthen the rearward plates against flexion along their lengths. The inner and outer plates, associated straps, and associated ribs form an inner tie portion for retaining a pair of form panels at a corner. An outer tie portion is connected to the inner tie portion so as to retain a second pair of form panels parallel to the first pair of form panels at a corner. The outer tie portion includes first and second plates connected at the same angle as the inner tie portion plates, a pair of straps extending from the plates to the ribs on the inner tie portion, and first and second paddles mounted rearwardly and parallel to the plates of the outer tie portion so as to retain a form panel between the panels and respective outer tie portion plates.
