Title
(EN) SEALED AND THERMALLY INSULATING TANK
(FR) CUVE ETANCHE ET THERMIQUEMENT ISOLANTE
Abstract
(EN)
The invention relates to a sealed and thermally insulating tank in which the sealing membrane of the end wall (102) has a first set of corrugations (118) that are parallel to the second wall (104, 106) and spaced apart at a first wave spacing y and a second set of corrugations (120) that are perpendicular to the second wall and spaced apart at the first wave spacing y, the sealing membrane of each longitudinal wall having a plurality of longitudinal corrugations, the longitudinal corrugations (126) of the first wall (108) being spaced apart at a second wave spacing z greater than the first wave spacing y and being connected continuously to one of the first and second sets of corrugations (120, 118) of the end wall by a corner arrangement, and wherein the angle (130, 132) between a plane of the first wall (108) and a plane of the second wall (104, 106) and a ratio between the first wave spacing y and the second wave spacing z are defined in a mutually corresponding manner.

L'invention concerne une cuve étanche et thermiquement isolante dans laquelle la membrane étanche de la paroi d'extrémité (102) comporte une première série d'ondulations (118) parallèles à la deuxième paroi (104), 106) et espacées d'un premier pas d'ondes y et une deuxième série d'ondulations (120) perpendiculaires à la deuxième paroi et espacées du premier pas d'ondes y, la membrane étanche de chaque paroi longitudinale comportant une pluralité, les ondulations longitudinales (126) de la première paroi (108) étant espacées d'un deuxième pas d'ondes z supérieur au premier pas d'ondes y et raccordées continûment à l'une des première et deuxième séries d'ondulations (120,118) de la paroi d'extrémité par un arrangement d'angle, et dans laquelle l'angle (130,132) entre un plan de la première paroi (108) et un plan de la deuxième paroi (104, 106) et un rapport entre le premier pas d'ondes y et le deuxième pas d'ondes z sont définis en correspondance l'un avec l'autre.
