Abstract:
A combined cable comprising a core cable of high-strength synthetic fibers, which take the form of a twisted bundle of monofilaments or a plurality of twisted bundles of monofilaments, and comprising an outer layer of steel wire strands, is characterized in that the bundle or bundles of monofilaments is or are stretched, with a reduction in diameter, and held in this state by a sheathing, in particular a braided sheathing. The extension under strain of the core cable under load is thereby reduced, so that the load distribution between the cross section of steel and the cross section of synthetic material of the cable improves.In order, in the same sense, conversely to make the strain behavior of the layer of strands approximate that of the core cable, the cable has an intermediate layer of an elastic synthetic material into which the steel wire strands are pressed while spaced apart from one another in such a way that the outer layer extends under load, and contracts radially.A strand can be analogously constructed.
Abstract:
A reinforcement for a building works structure comprising an assembly of solid wires. The wires are mutually parallel to form a bundle and the reinforcement comprises a sheath made of plastic material enclosing the bundle and providing it with cohesion.
Abstract:
A wire rope is disclosed, which has at most 18 outer strands and an independent wire rope core, with the strands of the core being laid in the opposite direction to the outer strands of the rope, and a nylon jacket is provided between the core and the outer strands of the wire rope.
Abstract:
A tension member, for use as a tendon or tether for a tension leg platform consisting of a plurality of carbon fiber filaments (6) gathered into a plurality of strands (5) in which the filaments (6) run against one another, around which strands there is arranged a sheath (16). The tension member comprises pressure-resisting spacers (7) having recesses (9, 11, 12, 14; 25, 26, 28, 31) wherein the strands (5) are laid singly so that they can move in the longitudinal direction unobstructed by each other and the spacers (7).
Abstract:
A method and machine for manufacturing and laying a plurality of elongate elements into an umbilical is shown. The umbilical comprises a core element a plurality of conduits and/or cables suited outside the core element, filler material around and between the conduits/cables and a protective sheath surrounding the conduits and filler material. The finished cable cord is characterized in that the filler material is in the form of inner, elongate channel elements having outwardly opening channels, adapted for receipt of the conduits/cables, and outer, elongate channel elements having inwardly opening channels adapted for receipt and final enclosure of the conduits/cables.
Abstract:
A core for wire rope has a fluted member (1) of polymeric or elastomeric material with symmetrically spaced helical grooves (2) each having the shape of an elliptical arc in cross-section in a plane normal to the core axis. The core may contain a reinforcing member, conductors, or optical fibers.
