Abstract

La présente invention concerne généralement un ensemble raccord permettant de raccorder des organes allongés non alignés en utilisant une combinaison constituée d'un raccordement pivotant et d'un raccordement tolérant comportant une tolérance qui ménage les extrémités des organes allongés non alignés. L'ensemble raccord de la présente invention se raccorde de manière pivotante au premier organe allongé ou au deuxième organe allongé et forme un raccordement tolérant avec l'autre. L'invention s'applique au raccordement d'une ancre de terre enfoncée dans le sol avec une tige de rallonge raccordée à une structure nécessitant un support, et ce, que l'ancre de terre et la tige de rallonge soient en alignement fonctionnel ou non. L'ensemble raccord forme des raccordements pivotants et tolérants qui coopèrent pour faciliter tout raccordement entre l'ancre de terre et la tige de rallonge, même après leur fixation sur une structure correspondante, et qui ne sont pas alignés.
