Clamp for connecting form panels with clamping jaws urging sections of panels together at their edges

A clamp (1) for connecting form panels which are disposed in coplanar, side-by-side relation and have edge sections (2), particularly hollow sections, at at least two confronting edges, particularly running round all the edges, said clamp comprising two clamping jaws (4) which are adapted to swivel towards and urge together oppositely directed longitudinal faces (2a) of abutting edge sections (2) and an actuating element for swivelling said clamping jaws (4), each clamping jaw (4) having an adjusting arm (5) arranged at an angle thereto and located at a jaw-end remote from a clamping point (4a) on jaw (4), said adjusting arms (5) being directed towards each other and in a corner area of each arm the clamping jaws (4) are swivel-mounted to a carrier (6) by swivel bearings (7), wherein the actuating element contacts each adjusting arm (5) at a point spaced from the swivel bearing (7), the points of contact being movable together with the adjusting arms (5) away from the form panels to be connected so as to close the clamp (1), and wherein the actuating element comprises a wedge (9) which in a use position is arranged between the points of contact on the adjusting arms (5) and the edge sections (2) of panels, the wedge (9) contacting the points of contact with a wedging face (9a) averted from the panels to be connected, whereby as the wedge (9) moves in a longitudinal direction it serves to close the clamp (1) by a wedging width of appropriately increasing dimension, the contact points being arranged at ends of the adjusting arms (5) remote from the swivel bearings (7) and being provided at an identical location comprising a common contact point, said ends of the adjusting arms (5) being swivel-connected to each other with play by a connector which forms the common contact point for applying the wedge (9), the wedge (9) being curved about an imaginary axis perpendicular to a plane in which the clamping jaws swivel, whereby an inner surface of the wedge curvature forms the wedging face (9a) which bears against the contact point of the adjusting arms (5), and an outer surface of curvature of the wedge forms a reverse face (9b) which engages the swivel bearings (7).
