A fire-resistant safe is made with internal (30, 44) and external (32, 46) shells that are filled with insulation material (34, 48). Hollow reinforcements interconnecting the two shells are formed as cone-shaped recesses (58, 62) in the internal shell (30, 44) having truncated bottom portions (60, 64) attached to the external shell (32, 46). The insulation (34, 48) is made of a water-bearing material and the recesses (58, 62) are made of a resin material that melts at a temperature in excess of the boiling point of water. Funnels (36, 38) are formed in the external shell (32, 46) for adding the insulation material (34, 48) in a liquid state. An escutcheon (24, 26) for covering the funnels (34, 38) is anchored to the insulation material (34, 38) by stakes (72, 76) that are embedded in the insulation material (34, 48) before the material hardens into place.

Cette invention concerne un coffre-fort à l'épreuve du feu formé de coquilles interne (30, 44) et externe (32, 46) remplies de matériau isolant (34, 48). Des pièces de renfort creux réunissant les deux coquilles prennent la forme, dans la coquille interne (30, 44), d'évidements coniques (58, 62) à partie inférieure tronquée (60, 64) solidaire de la coquille externe (32, 46). L'isolant (34, 48) est un matériau imbibé d'eau et les évidements (58, 62) sont faits de résine qui fond à une température supérieure au point d'ébullition de l'eau. Des entonnoirs (36, 38) sont ménagés dans la coquille externe (32, 46) pour pouvoir ajouter de l'isolant (34, 48) sous forme liquide. Une bride (24, 26) servant à recouvrir les entonnoirs (34, 38) est ancrée au matériau isolant (34, 38) au moyen de tiges (72,76) noyées dans l'isolant (34, 48) avant qu'il ne prenne en place.
