Shock absorber for rope structure, especially used for rockfalls, landslides, and snow fences

摘要

With an apparatus for the shock absorption of rope structures, in particular for rockfall, land slide and snow barriers, at least one intermediate piece (1; 1) deformable by tensile forces is provided which is accommodated within a rope subjected to tension. The intermediate piece (1, 1) comprises one or more longitudinal elements (7, 8, 20) which can respectively be in the form of a strip, bar, wire, rope and/or strand. The longitudinal element or elements (7, 8, 20) are connected by their one end (7a, 8a; 20a) to the one rope end. On the other hand, they are guided about a deflection element (10; 10) connected to the other rope end. Means are provided by means of which the deflection angle of the longitudinal element or elements formed upon loading the intermediate piece (1, 1) is substantially sustained. The shock absorption characteristics can thus be better defined and optimised.
