ABSTRACT:
A connecting device is provided for interconnecting two juxtaposed upright form panels used in forming a concrete wall. The form panels have adjacent mating edges between which an edge connecting plate is interposed tightly and removably. The connecting device includes first and second mounting plates secured respectively to the form panels adjacent to the mating edges of the form panels. Each of a pair of guide rods has an end portion extending through the first mounting plate and secured to the second mounting plate so as to permit relative lateral movement between the form panels. A driving screw has a threaded shank portion which extends through the first mounting plate and which extends threadably through the second mounting plate. A positioning screw has a threaded shank portion extending threadably through the second mounting plate and abutting against the first mounting plate. When the edge connecting plate is removed, and the positioning screw is loosened to move the positioning screw away from the first mounting plate, rotation of the driving screw in a predetermined direction causes movement of the first mounting plate toward the second mounting plate so as to facilitate stripping of the form panels from the concrete wall.
