Abstract

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.

First claim

The invention claimed is:

1. A structural cable of a construction work, the structural cable comprising:
a bundle of load-bearing tendons;
a sheath within which the bundle of tendons is located;
a housing within the sheath and fixed relative to the sheath, said housing having a concavity turned towards a longitudinal region of the sheath which includes openings, to define a cavity, extending longitudinally relative to the sheath,
wherein the bundle of tendons is located outside the housing and the cavity.

2. The structural cable of claim 1 , wherein the housing extends over at least 10% of the length of the structural cable.

3. The structural cable of claim 1 , wherein the housing is bonded to an inner surface of the sheath.

4. The structural cable of claim 1 , wherein the housing comprises a plurality of longitudinal segments aligned with one another along the length of the structural cable.

5. The structural cable of claim 1 , wherein the housing is substantially continuous longitudinally relative to the sheath.

6. The structural cable of claim 1 , further comprising:
at least one functional component arranged in said cavity.

7. The structural cable of claim 6 , wherein the at least one functional component comprises a fluid put in circulation in the housing, said fluid being configured to carry out a thermal function of the structural cable.

8. The structural cable of claim 6 , wherein the at least one functional component comprises at least one damping module configured to dissipate vibrations of the structural cable.

9. The structural cable of claim 6 , wherein the at least one functional component includes a plurality of light-radiating modules configured to radiate light each arranged at least in part in said cavity so as to radiate light through at least one of said openings outwardly relative to the structural cable.

10. The structural cable of claim 9 , further comprising:
for each opening among a plurality of openings, at least one reception element arranged in said opening, at least one light-radiating module being received within said reception element.

11. The structural cable of claim 10 , wherein the reception element is secured to the sheath, the reception element receiving at least one light-radiating module, the housing being held in said reception element.

12. The structural cable of claim 11 , further comprising:
a cover element arranged on the outer surface of the sheath,
wherein the reception element further comprises:
a flange arranged between the cover element and the outer surface of the sheath to maintain the reception element in position.

13. The structural cable of claim 12 , wherein the cover element includes reception holes receiving fastening elements which fasten the housing and the cover element to the sheath.

14. The structural cable of claim 12 , wherein for at least one opening, the outer surface of the sheath defines a flat spot surrounding said opening, the cover element having a flat inner face whose dimensions correspond to the dimensions of the flat spot.

15. The structural cable of claim 14 , wherein the cover element has a curved outer face whose curvature matches the curvature of the outer surface of the sheath so that the curvature of the cross-section of the structural cable is substantially constant in the region of the opening.

16. The structural cable according to claim 6 , wherein the at least one functional component includes a lightning protection cable.

17. The structural cable according to claim 16 , wherein the structural cable further comprises at least one lightning rod and at least one sacrificial module electrically connected to the lightning protection cable and respectively configured to attract lightning bolts and dissipate energy resulting from said lightning bolts.
