Clamp for connecting shuttering plates

摘要

The proposed clamp (1) is used for connecting shuttering plates (3) with edge profiles (2), having on their reverse sides a longitudinal surface (2a) with a recess (2b). The clamp (1) consists of a beam (6) with a support (12). On the beam (6) there are made swivel seatings (7) with clamping jaws (4) rotatably mounted by their central section thereon. The clamping jaws (4) first arm turned toward the stuttering plate (3) is provided at its end with a projection (4a) for fitting in the recess (2b). The clamping jaw (4) first arm and adjustment arm (5) form a right or obtuse angle and free ends of the adjustment arms (5) are oriented toward each other. On a wedge (9) there is performed a lock-out surface (9b) turned toward the stuttering plates (3) and a wedge surface (9a) that is turned away from the stuttering plates (3) and that is in engagement with the place of force action that is situated movably in the direction from the stuttering plate (3) surface. The lock-out surface (9b) is mounted slidably on the support (12) and the swivel seatings (7). The adjustment arm (5) ends turned toward each other are rotatably coupled with a clearance in a common pot of action of a force for a wedge (9) whose width increases between the wedge surface (9a) and the lock-out surface (9b) in the direction to its front side (16).
