The structural cable of a construction work comprises a bundle of load-bearing tendons, a sheath within which the bundle of tendons is located, and at least one vibration module received within the sheath and configured to generate vibrations to break superficial ice or frost deposits on the cable.

A deicing device for a sheath of a structural cable, the structural cable comprising tendons housed in the sheath, the deicing device includes a base; a bearing element; and a power system configured to press the bearing element against the tendons while the base is in contact with an inner surface of the sheath, and to generate vibrations between the bearing element and the base.

A snow and ice melt system having one or more zones, each including one or more heaters, and having one or more controllers configured to use a power output of each heater and an average temperature of each zone to determine operational control of each heater to achieve a specified result. Hydronic or resistive heaters could be used. The controllers may be configured to use a system temperature response over time to determine if a phase change of the snow or ice is occurring. The phase change might indicate that snow or ice is present on a zone and is melting. Use of a first derivative of the system temperature response over time might determine a percentage of a zone covered by snow or ice. Use of a second derivative of the system temperature response over time might determine whether melting is complete.

The structural cable comprises a bundle of load-bearing tendons extending between upper and lower anchoring devices, a first sheath containing the bundle of tendons, and a second sheath arranged around the first sheath, with a gap between the first and second sheaths.

The structural cable of a construction work comprises a bundle of load-bearing tendons, a sheath within which the bundle of tendons is located, and at least one vibration module received within the sheath and configured to generate vibrations to break superficial ice or frost deposits on the cable.

A sheath of a structural cable of a construction work, the structural cable being destined to comprise a bundle of tendons (20) destined to bear a load of the structural cable and to be received within said sheath, the sheath having an outer surface (30) and the sheath being made of a single layer of material (32) over at least a part of the length of the sheath.

The sheath comprises heating components (34) arranged within said single layer (32), the heating components (34) being configured for receiving electrical energy and, using said electrical energy, heating at least the outer surface (30) of the sheath so as to prevent ice, snow, rime or frost from forming thereon or remove ice, snow, rime or frost from the outer surface (30) of the sheath.

A structural cable of a construction work. The structural cable including a bundle of load-bearing tendons, a sheath within which the bundle of tendons is located, a housing located within the sheath and fixed relative to the sheath, said housing defining a cavity, the bundle of tendons being at a distance from the housing and the cavity, the bundle of tendons being located outside the housing and the cavity, said cavity extending longitudinally relative to the sheath.

The assembly comprises a structural cable comprising tendons (12) and a saddle deflecting the structural cable between the two ends thereof. The saddle comprises a body (18), conduits (24) formed in the body and each receiving one of the tendons of the cable, and two anchoring devices (20) which anchor the tendons by defining a first portion of the structural cable received in the saddle, where the tendons are subject to a prestressed tension that is constant over time and at least one second portion of the structural cable where the tendons are subject to tensions that are variable over time. An anchoring device (20) comprises an anchoring plate (28) comprising anchoring openings (36) each receiving one of the tendons, and wedges (30) each received in a respective anchoring opening of the anchoring plate in order to lock one of the tendons of the structural cable. The anchoring plate (28) has a rear surface bearing against the body (18).

The invention relates to an elongate tensioning unit comprising a casing which encloses an interior space, and a plurality of tensioning elements which extend in the longitudinal direction of the tensioning unit and are accommodated in the interior space of the casing. According to the invention, the casing comprises, at, at least one circumferential position, a depression which projects into the interior space and in which at least one electric functional unit, for example at least one lighting unit, and at least one connection line for the at least one electric functional unit are accommodated. Alternatively, the at least one electric functional unit can also be accommodated in an associated recess in a water-repelling element arranged on the outer surface of the casing.
