ABSTRACT:
A shear plug connector arrangement is formed by a bearing element (1) and a plug element (2) that can be introduced into the bearing element. The bearing element (1) comprises an outer sleeve and an inner sleeve (3 and 4, respectively). Between these two sleeves (3, 4), an elastic element (5) is arranged. The inner sleeve (4) and thus the plug element (2) introduced therein are mounted in floating fashion. This leads to a good footstep sound insulation. In accordance with the invention, a structure (7, 8, 9) is provided for limiting motion amplitudes at the bearing element (1) and/or at the plug element (2) so that the elastic element is not subject to excessive stresses and to ensuing short-term or long-term damage. The aforementioned structure is realized, for example, by an annular disk (8) on the front face of the inner sleeve (4), a nail plate (7) having a circular opening at the outer sleeve (3), and an interposed gap (9). The plug element (2) has a good inherent damping since it is constituted by a plug sleeve (11), a plug core (12), and a filling material (13) provided between sleeve and core.
