HOLLOW REINFORCEMENTS FOR FIRE-RESISTANT SAFES

摘要

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.
