METHOD FOR MANUFACTURING A FREESTANDING BODY FOR THERMAL INSULATION OF A VESSEL FOR STORING A FLUID AND FREESTANDING BODY PRODUCED THEREBY

摘要

The present invention relates to a method of manufacturing a magnetic-support case intended to provide a thermal insulation tank for a fluid storage tank having a fluid-tight membrane, comprising a plurality of supports Providing web 14; Providing a base panel 10 and a cover panel 11; The base panel 10 and the cover panel 11 are separated from each other in the thickness direction of the case 3 and 7 and the support web 14 is supported between the base panel 10 and the cover panel 11 so as to extend in the thickness direction Placing the web 14; Fixing the support web 14 to the base panel 10 and / or to the cover panel 11; And laminating a plurality of compartments (15) disposed between the support webs (14) with a thermal insulation lining, wherein each of the base panel (10) and the cover panel (11) Comprises at least one thermoplastic element (21, 22, 26, 29) for the purpose of forming a thermoplastic material; And the support web 14 is subjected to a thermoplastic welding process carried out in a boundary zone 25 between the base panel 10 and the thermoplastic elements 21, 22, 26, 29 of the cover panel 11 and the support web 14. [ Are fixed to the base panel and the cover panel. The present invention also relates to a fluid tight heat-insulated tank comprising a case made in this way and a heat insulating barrier comprising a plurality of cases as mentioned above.
