Abstract
The sheath (20) for a structural cable (10) has an outer surface to be exposed to an environment of a construction work equipped with the structural cable (10). The outer surface of the sheath has a roughness texture (30) to promote retention of frozen water. In at least an upper part of the length of the sheath (20), the roughness texture (30) covers more than half of the outer surface of the sheath.
Claims11
A sheath for a structural cable of a construction work, the sheath having an outer surface to be exposed to an environment of the construction work,
- wherein the outer surface of the sheath has a roughness texture to promote retention of frozen water, and wherein, 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,
- wherein the sheath comprises at least two helical ribs forming protrusions and extending along respective helical paths in opposite directions along the outer surface of the sheath, the roughness texture being located between the protrusions.
A sheath segment for forming a sheath for a structural cable of a construction work when assembled with at least one other segment, the sheath segment having an outer surface to be exposed to an environment of the construction work and provided with a roughness texture to promote retention of frozen water, wherein the roughness texture covers more than half of the outer surface of the sheath segment, the sheath segment comprising at least two helical ribs forming protrusions and extending along respective helical paths in opposite directions along the outer surface of the sheath segment, the roughness texture being located between the protrusions.
