Abstract (en)
[origin: WO8807423A1] Fireproof plate, longitudinally round or oval in shape, provided with a shrink ring on the circumferential surface and improved by external shaping, an elliptical circumferential surface (15) being provided with a clamping surface (7), disposed on at least one side of the principal vertex, transversely to the principal axis (5) of the elliptical plate and bearing the clamping stress. This contributes to the prevention of cracks, and the service life is thereby extended.
Abstract (fr)
Plaque ignifuge, de configuration ronde ou ovale dans le sens longitudinal, comportant une bague de serrage sur la surface périphérique. Ladite plaque est améliorée grâce à une conformation extérieure, une surface périphérique elliptique (15) présentant une surface de serrage (7) recevant la pression de serrage et configurée transversalement par rapport à l'axe principal (5) de l'ellipse, au moins sur un côté du sommet principal. On empêche ainsi la formation de fissures et la durée de vie s'en trouve accrue.
