Abstract

A clamping device for structural components includes a clamping rod and a clamping arm which can be pivoted from a clamping position into a ready position and vice versa. A rigid lever is rigidly connected through a pivot shaft to the clamping arm. A rigid bracket is rotatably coupled to the lever and to an end of the clamping rod. The length of the rigid bracket between the coupling joints is greater than the distance between the first coupling joint of the bracket with the lever and the longitudinal axis of the clamping rod in the ready position. The second coupling joint between the bracket and the clamping rod is supported on at least one roller which rolls on a forced guide unit which has a length portion corresponding to the pivoting angle of the clamping arm between the ready position and the clamping position, wherein this length portion extends in a straight line parallel to the longitudinal axis of the clamping rod in the ready position, and an end portion which is concave toward the first coupling joint with the coupling joint being in the dead center position thereof. The concave end portion begins in front of a plane which extends through the first coupling joint when the coupling joint is in the dead center position thereof and perpendicularly of the longitudinal axis of the clamping rod in the ready position and the concave end portion ends behind this plane.
