Patent

CA 2688286

The invention relates to a large-volume storage tank (100, 100') that comprises a closing section (200, 200', 200'') closed by a bottom (210, 210', 210''), another closing section (200, 200', 200'') or a bottom (400) and/or at least one intermediate section (300, 300', 300''), at least two of these neighbouring components being connected together by a junction means (500) including two collars (510) formed on the free annular ends of the two components and being opposite to each other, a plurality of bolts extending through both collars (510) for connecting the same. According to the invention, the junction means (500) includes a plurality of washers (522) mounted on the screws of the bolts (520) and provided between both collars (510) in order to define therebetween an annular volume (532) for receiving a sealing means (530). With this structure, the different components of the tank can be easily and very economically assembled and a calibrated width provision is contemplated for receiving a sealing means.

La présente invention concerne une cuve (100, 100') de stockage de grand volume comprenant un tronçon de fermeture (200, 200', 200'') fermé par un fond (210, 210', 210''), un autre tronçon de fermeture (200, 200', 200'') ou un fond (400) et/ou au moins un tronçon intercalaire (300, 300'), au moins deux de ces composants voisins étant réunis l'un à l'autre par l'intermédiaire d'un moyen de jonction (500) comprenant deux collerettes (510) réalisées sur les extrémités libres annulaires de ces deux composants en étant tournées en vis-à-vis, une pluralité de boulons (520) traversant les deux collerettes (510) pour les assembler. Selon l'invention,le moyen de jonction (500) comprend une pluralité de rondelles (522) montées sur les vis des boulons (520) en étant interposées entre les deux collerettes (510) pour former entre elles un volume annulaire (532) de réception d'un moyen d'étanchéité (530). Par cette construction, on assemble de manière économique et néanmoins très efficace les différents composants de la cuve et l'on prévoit une réservation de largeur calibrée pour réceptionner un moyen d'étanchéité.
