The method for manufacturing an individually sheathed strand comprises: conveying a group of metal wires through a die; upstream of the die, applying a first filler product to at least a first portion of the strand; upstream of the die, applying a second filler product to at least a second portion of the strand distinct from the first portion; and extruding a plastic around the group of metal wires passing through the die, so as to envelop the group of metal wires covered with the first and second filler products in a continuous sheath formed of the extruded plastic. The second filler product has greater adhesion to the group of metal wires than the first filler product.

Method for manufacturing an individually sheathed strand, strand thus obtained and strand manufacturing installation

The sheath () for a structural cable () has an outer surface to be exposed to an environment of a construction work equipped with the structural cable (). The outer surface of the sheath has a roughness texture () to promote retention of frozen water. In at least an upper part of the length of the sheath (), the roughness texture () covers more than half of the outer surface of the sheath.

Sheath for a structural cable

For an enclosure including a ground area (), a spectator area () around the ground area and a plurality of bearing points () around and above the spectator area, the method of mounting a roof structure comprises: assembling a tension ring () at the level of the ground area, the tension ring comprising at least one first cable extending along the tension ring and a plurality of connectors () spaced along the tension ring; attaching a plurality of second cables () to the plurality of connectors, each second cable having a first end connected to a respective one of the connectors and extending radially and outwardly from the tension ring, each second cable being associated with a respective one of the bearing points (); and lifting the tension ring by pulling the connectors () by the second cables ().

Method of mounting a roof structure

The proposed sheath is for a structural cable () having a path between an upper anchorage () and a lower anchorage (). It comprises sheath segments () assembled along the path of the structural cable, at least one supporting rope () extending along the sheath segments and having an upper end connected to the construction work adjacent to the upper anchorage, and connectors () for connecting the sheath segments to the at least one supporting rope. The connectors () are configured to block relative upward movement of the supporting rope () with respect to the sheath segments () and to allow relative downward movement of the supporting rope with respect to the sheath segments.

Sheath for a structural cable of a construction work, methods of installation and maintenance

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.

Structural cable having an inner housing

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.

A structural cable of a construction work. The structural cable including a bundle of load-bearing tendons, a first sheath containing the bundle of tendons, a second sheath arranged around the first sheath, the second sheath comprising windows, and a plurality of light-radiating modules configured to radiate light, each light-radiating module being arranged within the structural cable to radiate light through at least one window outwardly relative to the structural cable.

Dual-sheath structural cable

The invention has for object a method for manufacturing concrete construction blocks () for a wind-generator tower made up of at least two consecutive blocks secured to one another by a contact surface of each of the two blocks, the manufacturing method comprising the following steps:
