Abstract

La présente invention concerne les techniques de coffrages glissants. Elle a pour objet un extracteur destiné à extraire les barres d'appui de ces coffrages en fin d'ouvrage. Cet extracteur se caractérise en ce qu'il comporte deux demi-parties articulées entre elles et suceptibles d'etre refermées et bloquées sur la barre d'appui à extraire par des moyens de fermeture appropriés. D'un point de vue pratique, les deux demi-parties sont constituées de demi-coquilles cylindriques 1, 2, 3, 4 articulées entre elles (axes X, Y) et reliées entre elles par deux vérins 5, 6. Ces demi-coquilles renferment des galets 44 s'appuyant sur des surfaces coniques permettant un auto-blocage/déblocage de la barre au cours de mouvements de va-et-vient successifs et automatiques des vérins.
