| 摘要 |
Impermeable and insulating tank built into a load-bearing structure, the tank having two successive sealing barriers alternated with two thermally insulating barriers, the secondary barriers and the primary insulating barrier consisting of a set of prefabricated panels, each panel comprising, in succession, a first rigid board, a first thermal insulation layer (104), a second thermal insulation layer (108), and a second rigid board, the junction regions between the primary insulating barrier elements of two adjacent panels being filled with insulating titles each consisting of a thermal insulation layer (115) covered with a rigid board, the continuity of the secondary sealing barrier being provided in the junction regions of two adjacent panels by flexible strips (120) which are impervious to gas and to liquid, each strip being hermetically bonded to a secondary insulating barrier element of a panel by a lateral marginal region (120a) and to a secondary insulating barrier element of the adjacent panel by an opposite lateral marginal region (120b), so that its central region (120c), which covers the junction region, is free to deform elastically and/or elongate with respect to the insulating tiles.
