Abstract (en)
[origin: EP0078566A1] A barrier structure for safes and vaults including reinforcing members 3 designed to provide increased resistance to penetration by diamond drills. A cast concrete layer 2 is held to a backing plate 1 by anchors 4 and the reinforcing members 3 are welded to the anchors 4 so as to be embedded in the layer 2 when the concrete is cast onto the plate 1. The reinforcements 3 comprise tubes 5 which may be filled with a variety of elements which have been found to frustrate the diamond drill, such as tensile steel rods 7 ceramic rollers 8 and small rods or needles 9 of malleable metal.
