Abstract

L'invention concerne un procédé de réduction, à la mise en tension d'un câble de précontrainte, du frottement de ce câble contre la paroi du canal de logement du câble. Selon l'invention, le câble préalablement enduit d'huile passe dans un récipient 8 contenant un lubrifiant pulvérulent 9 avant d'être introduit dans son canal de logement 5. Application aux câbles courbes qu'ils soient disposés dans des structures type << poutres droites >>, ou des structures curvilignes, telles que réservoirs circulaires, enceintes de réacteurs, arcs.
