ABSTRACT:
An axial damper for elements having a cylindrical, rectangular or squared section, includes two identical fixing clamps, each fixing clamp including an upper part and a lower part connected to each other by a clamping device to be wound around the elements. At least two rafter-tie-rods are each connected at two ends thereof to the clamps. The rafter-tie-rods are placed equidistant from each other in the case of more than two rafter-tie-rods. The damper also includes two damping systems, each including two or more blocks of elastomeric material, with a pre-compressed elastic element interposed therebetween.
