Abstract
An armor plate wall structure for safes, security spaces at banks, and the like, being of a type which comprises an outer wall (2) and an inner wall (3) set at a fixed distance apart and defining an interspace (4) therebetween adapted to be filled with a security material (3), further comprises a plurality of brackets (11) made rigid with the outer wall (2) and extending vertically cantilever-fashion therefrom toward the interspace (4) over the full height of the wall (2). This structure (1) can validly resist attacks performed with the so-called de-lamination or exfoliation technique.
Description
- This invention relates to an armor plate wall structure for safes, security spaces at banks, and the like, being of a type which comprises an outer wall and an inner wall set at a fixed distance apart and defining an interspace therebetween adapted to be filled with a security material.
- As is known, the armor plate walls of safes or for security areas are usually formed by laminating together different materials each specifically designed to resist some particular thermal or mechanical tamper means.
- This invention is directed to fill a long-felt need for an armor plate wall which be specially resistant to tampering by the so-called de-lamination or exfoliation technique.
- The de-lamination technique consists of removing one by one all the material layers which make up the wall.
- To meet the above-noted demand, the prior art provides for the use of special steel alloys, such as manganese steel, or of some other composite materials, such as aluminum alloys, copper alloys, and cast irons inglobating corindon granules.
- While being generally advantageous, walls so formed have the drawback of being expensive to manufacture. In addition, not even the use of such expensive special materials can make a wall invulnerable to attacks performed with the de-lamination technique.
- The technical problem underlying this invention is to provide an armor plate wall structure for safes and the like, which has such construction and performance characteristics as to defeat any attacks carried out with a thermal or mechanical means, or the so-called de-lamination technique, thereby obviating the above-noted drawbacks affecting the prior art.
- This problem is solved by a wall structure being characterized in that it comprises, inside said interspace, a plurality of brackets made rigid with said outer wall in cantilever relationship therewith.
- The features and advantages of the wall structure according to the invention will become apparent from the following detailed description of an exemplary embodiment thereof, to be taken by way of illustration and not of limitation in conjunction with the accompanying drawings.
- In the drawings:
- Figure 1 is a top plan view of the wall structure according to the invention; and
- Figure 2 is a top plan view of a modified embodiment of the structure shown in Figure 1.
- With reference to the drawing views, the numeral 1 designates schematically an armor plate wall structure according to this invention. The structure 1 is particularly intended to form the peripheral armor of either a safe, not shown, or a security area of a bank.
- The structure 1 comprises an
outer wall 2 and aninner wall 3 held at a predetermined distance apart and defining aninterspace 4 intended for filling with a security material such as acement mix 5. - The
outer wall 2 is thicker than theinner wall 3, and is formed from large thickness plate metal, e.g. 10 to 15 mm thick. - More detailedly, the
walls flat flange portion 8 welded to theinner wall 3 and an opposedly located web 9 welded to theouter wall 4 all along its longitudinal extension. - Also provided are
holes 10 formed through the angle members 7 to put the various portions of theinterspace 4 in mutual communication for improved spreading of thecement mix 5. - Advantageously according to the invention, there are provided a plurality of brackets 11 made of some metallic material which are made rigid with the
outer wall 2 in cantilever relationship therewith inside saidinterspace 4. Each of said brackets 11 extends along a vertical direction and is welded to thewall 2 by means of a so-calledstress weld 12. The brackets 11 are laid at close intervals and, in a preferred embodiment, placed at constant pitch spacings of 5 cm. - Each bracket 11 is welded to the wall throughout its vertical extension. Each bracket 11, moreover, projects inwardly of the
interspace 4 by approximately one half the thickness of the latter. - Understandably, the invention also contemplates the provision of a number of bracket segments in vertically aligned relationship and affixed leaving gaps therebetween.
- A modified embodiment will be now described of the wall structure according to the invention. In this modified embodiment, items and cooperating parts which have the same structure and perform in the same manners as in the former embodiment are denoted with the same reference numerals.
- With reference to Figure 2, a
wall structure 15 according to the invention comprises box-typestiffening rib formations 13 each affixed to either walls, 2 and 3. Theribs 13 have an isosceles trapezoidal cross-section shape with the major base removed and the minor base portion welded to theinner wall 3. - Formed in turn through
such ribs 13 areholes 10 for passing and distributing thecement mix 5. Further, thelongitudinal edges 16 of eachrib 13 are welded to thewall 2 bystress welds 12 spanning the full height of the wall. - The wall structure according to the invention is easily manufactured and exhibits a high resistance to drilling, while effectively opposing any attacks performed with the de-lamination technique.
- In particular, this structure can be assembled from inexpensive non-special materials, since its strength comes more from the monolythic character of its construction than the nature of the materials employed.
- Should this structure be attacked with thermal means in an attempt to cut the outer wall along a closed line, to then pry it up by means of a crowbar, the brackets provided inside the interspace resist such a bending effort by acting in constraint. A thermal means, moreover, would meet at the point of attachment of each bracket to the wall a change in the material thickness effective to make the cut quite difficult to perform.
- The wall structure of this invention has the additional advantage of being strengthened by the stress welds spanning the full vertical extension of the connected members, and that it can be easily filled with the security material throughout.
