Composite rope and anchoring and safety system
A composite rope (10-1; 10-2) comprising: an inner metallic core (10-A) laid from a plurality of twisted wire strands (10-A'), and a plurality of covering layers formed around the inner metallic core (10-A), wherein the covering layers comprise a first layer (10-B) at least braided with aramid yarns, such as Kevlar (R), and formed around the inner metallic core (10-A), and a second layer (10-C) at least braided with polyester yarns and formed around and covering the first layer (10-B). Additionally, the covering layers may comprise a third layer (10-C) braided with p-aramid (Kevlar (R)) yarns and/or yarns of UHMWPE fibers (Dyneema (R)), which is formed around and covers the second layer (10-C). In case of reaching the tensile strength of the composite rope (10-1; 10-2), the composite rope breaks totally and completely only in stages, namely first the metallic core (10-A) and subsequently the layers (10-A, 10-B, 10-C). An anchoring and safety system (20), based on the use of a rope and directed to put in safety roofs (RO) and the roofing of buildings against accidental falls from a height of people working on them, comprising one or more anchorages (21) fixed to the roof (TE) to make safe and sure, in each of which the rope (E) is stably locked by screwing, so as to avoid issues of instability for the people that are attached to the rope.
