Abstract
The structural cable has several stretched tendons (4). It is diverted in a device comprising a body crossed by conduits (10). Each conduit has a wall to guide one of the tendons along a curved path. The wall of the conduit has a tendon support area (11) directed toward the interior of the curve of the path. This support area presents, in the center portion of the conduit and transverse to the curved path, a section in the shape of a circular arc whose radius is appreciably equal to half the external diameter of the tendon. The central portion of the conduit has a cross-section enlarged outside the support area.
Claims18
A device for deviating a structural cable having a plurality of stretched tendons, the device comprising:
- a body;
- and
- conduits extending through said body,
- wherein each conduit has a wall to guide one of the tendons along a curved path, the conduit wall having a support area for supporting said one of the tendons, wherein said support area is located on an interior side of the curvature of the path and has, at least in a central portion of the conduit and transverse to the curved path, a cross-section in the shape of a circular arc having a radius substantially equal to half the external diameter of said one of the tendons, the central portion of the conduit having a widened cross-section outside the support area.
A construction work, comprising:
- at least one structural cable having a plurality of stretched tendons;
- anchors for the tendons at the extremities of the cable;
- and
- at least one cable deviation device between the anchors,
- wherein the deviation device comprises a body and conduits extending through said body, wherein each conduit has a wall to guide one of the tendons along a curved path, the conduit wall having a support area for supporting said one of the tendons, wherein said support area is located on an interior side of the curvature of the path and has at least in a central portion of the conduit and transverse to the curved path, a cross-section in the shape of a circular arc having a radius substantially equal to half the external diameter said one of the tendons, the central portion of the conduit having a widened cross-section outside the support area.
