Abstract
The structural cable has a bundle of substantially parallel tendons contained in at least one plastic protective sheath section. The plastic material of the sheath section extends between the tendons to form a coherent matrix for spacing the tendons. The cable may be used as a pre-stressing cable, a stay cable or a carrying cable for suspension bridges.
Claims18
Structural cable for civil engineering works comprising at least one bundle of substantially parallel tendons contained in at least one plastic sheath section, wherein the sheath section is a prefabricated product and the plastic material of the sheath section extends between the tendons to form a coherent matrix for spacing the tendons.
Method for laying a structural cable in civil engineering works, comprising:
- providing a sheath having at least one section forming a coherent spacing matrix and having substantially parallel longitudinal bores;
- inserting respective tendons into at least some of the bores of the sheath section;
- and
- tensioning the tendons.
