Abstract

La présente invention concerne un appareil d'appui pour ouvrage d'art (10, 31) qui comporte un corps glissant (12), doté d'une surface de base (16) et d'une surface de glissement incurvée convexe en forme de calotte sphérique, et un logement (14) destiné à supporter de façon mobile le corps glissant (12). Le logement (14) comporte une surface (20) incurvée concave en forme de calotte sphérique et il entoure au moins partiellement la surface de glissement (17) du corps glissant (12). Le but de l'invention est de proposer un nouvel appareil d'appui pour ouvrage d'art qui a une configuration particulièrement compacte et qui peut être mis en place de façon particulièrement souple. Ce but est atteint grâce au fait que le logement (14) comporte au moins une surface latérale (21 ; 22) qui est disposée de telle sorte qu'elle borde la surface (20) du logement de façon à ce que celle-ci ait un bord (13) dont la hauteur, par rapport au point le plus bas (Ta) de la surface (20) incurvée concave du logement, présente une allure variable dans la zone de la surface latérale (21 ; 22) du logement. Ainsi, le dispositif d'appui (10, 31) a, en comparaison, une configuration particulièrement compacte.
