METHOD FOR PRODUCING A SEALED AND THERMALLY INSULATING BARRIER FOR A STORAGE TANK

摘要

A method for producing a sealed and thermally insulating wall for a fluid storage tank includes attaching plural anchoring elements to a support structure; installing modular formwork elements on the support structure, the modular formwork elements having a shape that protrudes relative to the support structure and that defines, with the support structure and the plurality of anchoring parts, compartments having an open side opposite the support structure; spraying insulating foam into the compartments through the open side to form plural insulating sectors made from sprayed insulating foam; arranging insulating junction elements in a stressed position in which they are stressed between the insulating sectors and capable of expanding when the insulating sectors contract, to ensure continuity of the thermal insulation; and attaching a sealing membrane to the anchoring elements.

1. A method for producing a sealed and thermally insulating wall for a fluid storage tank, comprising the steps of:
attaching a plurality of anchoring elements (1) to a support structure (2); installing modular formwork elements (3) on the support structure (2), the modular formwork elements (3) having a shape that protrudes relative to the support structure (2) and that defines, with the support structure (2) and the plurality of anchoring parts (1), mutually adjacent compartments (4) having an open side opposite the support structure (2), two mutually adjacent compartments being separated in each case by a modular formwork element positioned between them; spraying insulating foam into said compartments (4) through the open side so as to form a plurality of insulating sectors (5) made from sprayed insulating foam; arranging compressible insulating junction elements (8) in a stressed position in which they are stressed between said insulating sectors (5) and capable of expanding when said insulating sectors (5) contract, so as to ensure continuity of the thermal insulation; and attaching a sealing membrane (9) to said anchoring elements (1).
