Definitions
- the present invention relates to security barrier structures and aims in particular to provide a structure having a high degree of resistance to penetration by the action of explosive charges applied to the outer surface of the structure.
- Barriers in accordance with the invention are intended especially for use in the construction of doors for buildings or other structures which are liable to come under explosive attack at the hands of burglars or saboteurs for example, although they may also find utilisation in the walls or other fixed boundaries of such structures.
- the prior art provides many barrier structures intended for use in, for example, the doors of bank vaults and the like security enclosures, which are designed to provide a high degree of resistance to penetration with drills, punches, flame-cutting equipment and other mechanical and thermal tools commonly appropriated by burglars.
- the materials and modes of construction employed in these structures are not well suited to resist the effects of high-explosive surface charges of even modest proportions. It is to the provision of structures providing protection from this kind of attack that the invention is principally directed, it being recognised that there is currently a demand for the protection of various kinds of building from explosive attacks which may be mounted not with burglarious intent but with the aim simply of causing damage to the structure and its contents or occupants.
- the purpose of the aforesaid timber layer is to act as a shock absorber to protect the structure behind it from blast effects and also as a thermal insulator to reduce the transmission of heat to the structure behind it, so that the rearward portion of the structure can be protected from the influence of an explosion occuring at or near to the exposed surface of the structure, and retain its integrity as a physical barrier notwithstanding the partial destruction or breaching of the portions of the structure in front of it.
- the blast pressure effects resulting from the explosion are dispersed in air space 6 over a large area of the timber layer 5, thereby to avoid or minimise a concentration of pressure on a relatively small area of the timber. If a sufficient pressure force is exerted on the inner face of front plate 2 in the direction of arrow X in Figures 1 and 2, the rivets 3 will give to permit front plate 2 to be blown off the frame 1, thereby further to dissipate the blast and minimise its destructive effect on the timber layer 5.
- Timber layer 5 confers resistance to an explosive attack upon the door by acting to absorb physical shock and to reduce the transmission of heat through the door to the steel back plate 4 behind it.
- the door A is hinged at 7 to an associated door frame B and can be provided with a suitable fastening mechanism comprising, for example, bolts (not shown) to be thrown into the frame B through the opening side edge of the door in response to manipulation of an external handle 8, together with fixed stud bolts 9 on the hinge side edge of the door.
- a suitable fastening mechanism comprising, for example, bolts (not shown) to be thrown into the frame B through the opening side edge of the door in response to manipulation of an external handle 8, together with fixed stud bolts 9 on the hinge side edge of the door.
- a test door was constructed generally in accordance with Figures 1 to 3 hereof and having the following characteristics: plate 2 was 3mm thick mild steel; plate 4 was 10mm thick mild steel; the frame sections 1 were 50mm square, 2.5mm wall thickness steel tube; the internal space between the plates 2 and 4 was 50mm deep; and the timber layer 5 comprised 40mm thick maranti boards.
- This specimen was mounted in a typical frame and a limpet mine having a charge of 0.95kg of Tritanol explosive was applied to the surface of plate 2. When the charge was detonated the plate 2 was blown off and the timber 5 fell out, but the plate 4 attached to sections 1 remained intact and bolted to its frame, with some plastic deformation, so that the brrier as a whole was not breached.
- Figures 5 and 6 show a barrier structure for incorporation into a blast-resistant door which may withstand rather heavier charges than those of Figures 1 to 4 and which, in the illustrated embodiment, is designed also to be fire resistant.
- the barrier comprises essentially a double box-like structure.
- One "box" is composed of a steel plate 11 - which provides the outer face of the structure - attached to an intermediate steel plate 12 via framing sections 13, and stiffened by horizontal angles 14.
- the other "box” is compsed of a steel back plate 15 welded to the plate 12 via framing sections 16 and horizontal stringers 17.
- Within the first of these compartments there is a layer of timber 18 fronted by a layer of kieselguhr (diatomaceous earth) 19.
- the rearward compartment between plates 12 and 15 will house a driving and locking mechanism (not shown) to throw door bolts into an associated frame, or alternatively the door may be locked by bolts thrown into engagement with sockets in the door (at the positions indicated at 20 in Figure 1) from a mechanism housed in the associated frame.
- a driving and locking mechanism (not shown) to throw door bolts into an associated frame, or alternatively the door may be locked by bolts thrown into engagement with sockets in the door (at the positions indicated at 20 in Figure 1) from a mechanism housed in the associated frame.
- the purpose of the timber layer 8 in this structure is, as before, to confer resistance to an explosive attack upon the door by acting to absorb physical shock and to reduce the transmission of heat through the door to the steel behind it. To demonstrate the efficacy of this type of structure the following test was conducted.
- a test specimen was constructed substantially in accordance with Figures 5 and 6 hereof and having the following characteristics: the overall thickness of the structure was 273mm; plate 11 was 3mm thick mild steel; plate 12 was 20mm thick mild steel: plate 15 was 10mm thick mild steel; the timber layer 18 was composed of 40mm thick maranti planks; and the kieselguhr layer 19 was 100mm thick.
- the specimen was supported in a rig to simulate its mounting to the associated door frame and a 3.33kg charge of type PE4 (cyclonite-based) plastic explosive (equivalent to about 5kg of dynamite) was applied to the surface of plate 11.
- type PE4 cyclonite-based plastic explosive
- the kieselguhr layer 19 is provided to confer general fire resistance to the structure, and is not thought to make a significant contribution to blast resistance of itself. By replacing the layer 19 in this structure with further timber, therefore, resistance to even heavier charges of explosive may be obtained.
