A method for producing a synthetic tensile member having a precisely known and stable length. The invention also comprises equipment configured to carry out the method. A tensile member is prepared by attaching terminations to an assembly of synthetic filaments. The tensile member is then attached to a loading apparatus that subjects the tensile member to a pre-defined loading process. The tensile member is thereby conditioned to a stable length. The length is then measured and a length adjusting component is incorporated into the tensile member to create a precise and stabilized length that is configured for the tensile member's particular application.

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 proposed sheath is for a structural cable (10) having a path between an upper anchorage (16) and a lower anchorage (17). It comprises sheath segments (21) assembled along the path of the structural cable, at least one supporting rope (30) extending along the sheath segments and having an upper end connected to the construction work adjacent to the upper anchorage, and connectors (32) for connecting the sheath segments to the at least one supporting rope. The connectors (32) are configured to block relative upward movement of the supporting rope (30) with respect to the sheath segments (21) and to allow relative downward movement of the supporting rope with respect to the sheath segments.

In a method for manufacturing a cable, a filling step S5 of filling a tube hole of a socket main body which is formed in a tubular shape and in which first end portions of wire rods are disposed with a mixture obtained by mixing a thermosetting resin into a preliminary mixture obtained by mixing ceramic particles and fly ash in advance is carried out.

A preassembled parallel wire cable creates a random cast of loops. Any of the random cast of loops is hung for transport, thus eliminating costly and time-consuming coiling and reeling operations.

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.

The present invention relates to a hybrid pipe (1) for stay cable, comprising a tubular shaped wall (15), the wall having an internal face (18) and an external face (19). The hybrid pipe (1) further comprises at least one reinforcing element (12, 22), the reinforcing element (12, 22) being provided at the wall (15) to form the hybrid pipe (1) such that the hybrid pipe (1) has a higher mechanical properties/resistance such as higher buckling resistance, higher tensile strength and/or a lower thermal dilatation than the wall (15) itself. The present invention also relates to a cable-stayed system comprising such a hybrid pipe (1) and a method of manufacturing such a hybrid pipe (1).

The invention relates to the technological field of bridge structures, in particular to a long-service-life PWS cable with replaceable sleeve and shielding gas. It consists of wire strands, wrapping tape covering the wire strands, and a sheath arranged outside the wire strands, and is characterized in that the sheath is covered with an outer protective sleeve and shielding gas is filled between the wires in the wire strands. The wire strands of the present invention is completely under protection in a shielding gas environment which effectively avoids the corrosion of the wire strands; the protective sleeve outside the sheath of the PWS cable is a replaceable segmented and fragmented sleeve structure, which is convenient to be replaced and installed, substantially prolonging the service life of the PWS cable system with great promotional value achieved.

A parallel wire cable is produced from a plurality of wires arranged in a bundle for use as a structural cable. Each wire in the plurality of wires is parallel to every other wire in the bundle, and each wire in the plurality of wires is tensioned to a tension value.
