Abstract

L'invention porte sur un assemblage d'angle (4, 16), en particulier pour une tour de turbine éolienne (1), lequel assemblage relie quatre segments de tour adjacents (5, 6, 7, 8) par des parties (9, 10, 11, 12) incurvées vers l'intérieur le long d'une direction horizontale ou verticale, ce par quoi les longueurs des parties incurvées vers l'intérieur (9, 10, 11, 12) le long de la direction horizontale ou verticale sont alternées et deux parties incurvées vers l'intérieur (9, 10, 11, 12) le long de la direction horizontale ou verticale forment un joint bout à bout, ce par quoi la ou les plaques d'assemblage (17, 18) sont reliées au joint bout à bout.
