An apparatus for grinding surfaces comprising a frame (1, 2), machine tools (3, 4, 5, 6, 7) attached to the frame, and several bearing elements (11, 12, 13, 14, 15, 16) attached to the frame which include a bearing surface (20) leaning on the surface to be ground and/or some other stop surface (T1, T2, T3) and adapted to its shape, and equipment for forming an air or liquid cushion between said bearing surface (20) and stop surface (T1, T2, T3). In an apparatus of the present invention, the attachment of at least one bearing surface (11-16) to the frame (2) comprises controllable adjusting equipment (18) for adjusting the position of the bearing surface (20) in relation to the frame. The present invention provides an apparatus which is especially adapted for grinding surfaces in massive constructions on site. The apparatus may be used in a versatile way, and work may be initiated and carried out quickly without any large-scale preparations.

Un appareil pour meuler des surfaces comprend un cadre (1, 2), des outils d'usinage (3, 4, 5, 6, 7) fixés au cadre et plusieurs éléments d'appui (11, 12, 13, 14, 15, 16) fixés au cadre et comprenant une surface d'appui (20) plaquée contre la surface à meuler et/ou une autre surface d'arrêt (T1, T2, T3) en étant adaptée à la forme de cette surface d'arrêt. L'appareil comprend, également, un équipement pour former un coussin d'air ou de liquide entre la surface d'appui (20) et la surface d'arrêt (T1, T2, T3). Dans un appareil selon l'invention, le dispositif de fixation d'au moins une surface d'appui (11-16) au cadre (2) comprend un équipement d'ajustement commandé (18) permettant d'ajuster la position de la surface d'appui (20) par rapport au cadre. L'appareil de l'invention est particulièrement bien adapté au meulage in situ des surfaces dans des installations de grande taille. L'appareil est très adaptable et il peut être mis en oeuvre rapidement sans grandes préparations.
