Abstract
A foam panel concrete form is provided for using connectors which extend on each side of a joint in the foam panel concrete form and into complementary shaped openings in ties which hold two adjacent panels in a spaced and parallel relationship. The connector can pass into the openings in adjacent ties with little resistance in a first rotary position of the connector. After the connector is inserted a predetermined distance into the openings, then the connector is rotated to a second rotational position within the openings so that flanges of the connector are disposed on each side of respective ties and thereby hold adjacent ties and the adjacent foam panels in a substantially fixed relationship with respect to each other during a time when concrete is poured between the foam panels.
