Abstract

L'invention concerne un élément d'isolation thermique (1) qui est placé entre deux structures à bétonner, notamment entre une structure portée (A) et une structure porteuse (B) d'un bâtiment, et qui est au moins constitué d'un corps isolant thermique (2) à intercaler, au moins muni d'éléments de pression intégrés (3) qui traversent le corps isolant thermique (2) et peuvent être respectivement raccordés aux deux structures (A, B). Ces éléments de pression (3) sont respectivement constitués d'une pièce (4) qui s'étend transversalement à travers le corps isolant thermique et aux extrémités opposées de laquelle s'aboutent par complémentarité de forme des pièces terminales (5, 6) reliées de manière fixe à la pièce s'étendant transversalement à travers le corps isolant thermique. Ces pièces terminales présentent respectivement un profil de contact courbe au niveau de leurs faces frontales (9,10) orientées vers les structures (A, B) de sorte que les éléments de pression (3) établissent une liaison articulée entre les deux structures (A, B).
