Thrust testing device for determining shearing strength of materials, has frame parts connected to frame, and load introduction elements for introduction of test load at pivots that lie diagonally opposite to each other

摘要

The device has four identical frame parts (2.1) connected to a thrust frame by pivots in an articulated manner. The thrust frame is arranged opposite to a measurement surface (1.1) of a sample body (1) in a displaced manner, such that the sample body is fixable on a side of a clamping element (3) that embraces the thrust frame by the frame parts. Load introduction elements are arranged for introduction of a test load at the pivots that lie diagonally opposite to each other. A mechanical linkage holds two push plates with centre of gravity over a midpoint of the measurement surface.
