Definitions

  • the present invention relates to a security fence panel and security fencing created therefrom.
  • Security fencing is typically used for the construction of perimeter fences around prisons and other high security buildings, at national borders or around oil refineries and the like which may be located in hostile environments.
  • Security fencing is typically constructed of welded steel wire mesh or other high strength material and is normally designed to resist unaided climbing ("anti-climb”) and sometimes also to resist attack by power tools such as angle grinders (“anti-grind”) or bolt cutters. In some situations, it is also desirable to offer some protection against projectiles, even including bullets.
  • Anti-climb security fencing typically employs mesh openings that are too small to allow handholds or footholds, and a gauge of wire that is too thick to be easily cut with bolt cutters.
  • EP3149260B1 discloses a fencing mesh having a first set of wires which are arranged essentially parallel with respect to each other and a second set of wires which are arranged essentially parallel with respect to each other and intersect the first set of wires, wherein the wires of the first set of wires are connected to the wires of the second set of wires at locations where they intersect.
  • the wires of the first set of wires are connected to the wires of the second set of wires by welding.
  • a fencing mesh as disclosed in EP3149260B1 has the disadvantage that it can be damaged or destroyed by an intruder, for example by an intruder using a grinding tool.
  • WO2017/194977 describes a security barrier assembly, including a plurality of elongate, longitudinally extending, substantially parallel ridge formations.
  • WO2012/107745 describes a security wall comprising first and second security barriers and at least one connection member, the first and second security barriers comprising at least one compartment bounded at its front by a front panel for providing a barricade, at its rear by a rear panel, at its sides by respective side panels connecting the rear and front panels, and at its bottom by a bottom panel connected to at least two of the front panel, the rear panel, and the respective side panel.
  • An object of the present invention is to provide security fencing with improved anti-grind features.
  • WO2019/197874 discloses a fencing mesh assembly comprising a front mesh panel, a rear mesh panel and several cross mesh (i.e. intermediate) panels, wherein the cross mesh panels are disposed between and are connected to the front mesh panel and the rear mesh panel, and are distributed over the front mesh panel and over the rear mesh panel, wherein in the installed state, adjacent cross mesh panels are arranged spaced apart from each other, and wherein in the installed state the front mesh panel and the rear mesh panel are spaced apart from each other.
  • WO2019/197874 is security fencing. However, WO2019/197874 only discloses constructions having horizontal cross mesh (i.e. intermediate) panels.
  • the aim of the present invention is to provide a security fencing with improved anti-grind properties, as well as anti-climb properties and projectile resistance.
  • a security fence panel comprising mutually confronting security mesh sheets which in use are spaced apart, the security mesh sheets being connected by intermediate sheets wherein in use the intermediate sheets are inclined to the horizontal and extend across the space between the confronting security mesh sheets.
  • the security fence panel further comprises a plurality of intermediate sheets per pair of security mesh sheets, the plurality of intermediate sheets spaced between 100mm and 500mm apart from one another.
  • fence panel is to be construed in accordance with the normal use of the word to relate to a panel that can be used in combination with fence posts to create a fence.
  • the fence panel is therefore not self-supporting and is not sufficient to create a fence or other barrier alone, without some form of support.
  • a security fence panel is to be construed to mean a fence panel that has anti-grind properties (i.e. an anti-grind fence panel).
  • Anti-grind may be defined with reference to ASTM F2781-10, in that a fence panel is considered anti-grind if it meets one of the ratings in this document.
  • a security fence may be anti-grind if it withstands attack with a grinding tool for at least 5 minutes, as stipulated in ASTM F2781-10.
  • the fence panel has a length, a height and a depth.
  • the height of the fence panel is the distance along the security mesh sheet in the direction perpendicular to the surface on which it is to be positioned.
  • the length of the fence panel is the distance along the security mesh sheet in the direction parallel to the surface on which it is to be positioned.
  • the depth of the fence panel is the distance between the external faces of the two security mesh sheets.
  • the fence panel does not have to be positioned on a surface in order to have such dimensions and these dimensions are intended to improve the clarity of the definitions herein only.
  • the fence panel has a height even when not positioned on a surface and it may be clear to the skilled person based on the arrangement of the fence panel which dimension is the height and which is the length.
  • One dimension of the panel may be longer than the other.
  • the intermediate sheets may extend along at least part, if not all, of the longer dimension.
  • the height of the fence panel may be longer than the length of the fence panel.
  • the intermediate sheets may extend along at least part of the height of the fence panel.
  • the intermediate sheets may extend along the entire height of the fence panel.
  • the intermediate sheets can transfer forces acting on one security mesh sheet to the other security mesh sheet, thereby increasing the strength of the security fence panel.
  • the intermediate sheets connect the security mesh sheets at a plurality of positions along the length of the security fence panel.
  • the intermediate sheets are substantially vertical panels. Vertical is defined relative to the surface on which the fence panel is to be positioned, which defines the horizontal.
  • the intermediate sheets may therefore have an inclination to the horizontal of about 90 degrees.
  • the intermediate sheets have an inclination to the horizontal in the range of 50 degrees to 90 degrees, preferably in the range of 60 degrees to 90 degrees, most preferably in the range of 75 degrees to 90 degrees.
  • the intermediate sheets are connected sufficiently loosely to the security mesh sheets to allow movement of the sheets relative to one another, for example when attacked with a power tool. Preferably, only a small amount of movement is allowed.
  • This feature enhances the anti-grind properties of the fence panel by making it difficult to keep the cutting edge of the grinding disc in one position when attacking the fence. Indeed, the sudden movement of the mesh sheets when engaged by the rotating periphery of the grinding disc may even break the disc in some circumstances.
  • the intermediate sheets are connected sufficiently loosely to the security mesh sheets to allow movement of at least 2mm, preferably at least 5mm within the connection.
  • the panel may comprise more than two intermediate sheets extending between the mutually confronting security mesh sheets, preferably more than five intermediate sheets extending between the mutually confronting security mesh sheets. This can increase the time required to breach the panel.
  • the intermediate sheets may be attached to every other vertical wire in the security mesh sheets. There may be two vertical wires in the security mesh sheets between those to which the intermediate sheets are attached. There may be three vertical wires in the security mesh sheets between those to which the intermediate sheets are attached.
  • the intermediate sheets are parallel to each other.
  • the intermediate sheets are pivotally connected to the security mesh sheets to allow stowage of the security mesh fencing in a collapsed state prior to erection. This feature facilitates storage and transport of the security fence panel.
  • the intermediate sheets are pivotally connected to the security mesh sheets by spiral connectors threaded through the mesh of the security mesh sheets.
  • This construction typically allows significant movement of the security mesh sheets relative to the intermediate sheets when attacked by an angle grinder, thereby enhancing the anti-grind security of the fence panel. Additionally, this provides a secure connection requiring little material, thereby reducing the weight of the panel and improving the visibility.
  • a spiral connecter can be fitted easily but is difficult to remove without specialised tools and suitable access to the end of the spiral connector. It also provides a connection along the length of the spiral connector.
  • the intermediate sheets are formed of mesh.
  • the spiral connectors are threaded through the mesh of the intermediate sheets and the mesh of the security mesh sheets.
  • the intermediate sheets may be connected to the security mesh sheets along their longest dimension. This can be achieved using the spiral connector. In this manner, the destruction of the connection means at one point along the longest dimension of the intermediate sheets does not separate said sheets from the security mesh sheets, as there will still be connections along the rest of the intermediate sheet.
  • the term "mesh" is to be construed to cover solid interconnecting wires.
  • the mesh may comprise a plurality of wires extending parallel in a first direction and a plurality of wires extending parallel in a second direction perpendicular to the first, such that each of the wires in the first direction intersects each of the wires in the second direction.
  • the wires may be formed from metal, preferably steel.
  • the wires may be connected together, preferably at each intersection.
  • the wires may be welded together.
  • the mesh of the security mesh sheets and the intermediate sheets may be the same.
  • the spiral connectors may have an internal diameter that is greater than the thickness of the wires in the mesh, thereby creating a loose connection such that the intermediate sheet can move relative to the security mesh sheets.
  • the security mesh sheets may have a height of at least 1.7m, and preferably have a height of at least 1.9m.
  • the height of the security mesh sheets may be greater than 3m.
  • the height of one of the security mesh sheets in the security fence panel may be greater than the height of the other security mesh sheet.
  • the intermediate sheets may extend the height of the shorter security mesh sheet.
  • the height of the security mesh sheet intended to be on the side of the attacker may be greater than the height of the security mesh sheet intended to be on the side away from the attacker. This can help to reduce the weight and cost of the fence panel without greatly reducing protection from the attacker.
  • the width of the security fence panel and/or the security mesh sheets may be more than 1.5m, and preferably more than 2m.
  • the depth of the security fence panel (i.e. the distance between the security mesh sheets) may be between 100mm and 450mm, preferably around 300mm. This is greater than the radius of a commonly available angle grinder disc, thereby increasing the difficulty with which such a tool can breach the security fence panel as an attacker is prevented from reaching one security mesh sheet by the other security mesh sheet.
  • the security mesh sheets are preferably parallel to one another.
  • the intermediate sheets are spaced apart from one another.
  • the intermediate sheets within the security fence panel are between 100mm and 500mm apart from one another. There may be between 5 and 15 intermediate sheets in each security fence panel.
  • the intermediate sheets may be rectangular, with a longer dimension and a shorter dimension.
  • the longer dimension of the intermediate sheets may be substantially equal to or shorter than the height of the security mesh sheets.
  • the longer dimension of the intermediate sheets may be greater than 1.7m, preferably greater than 1.9m and most preferably around 3m.
  • the shorter dimension of the intermediate sheets may be substantially equal to (can be a little smaller) or greater than the depth of the security fence panel, as defined by the spacing between the security mesh sheets.
  • the shorter dimension of the intermediate sheets may be between 100 and 400mm.
  • One edge of the intermediate sheet along the longer dimension may be connected along its length to one security mesh sheet, while the opposite edge along the longer dimension may be connected along its length to the other security mesh sheet in the fence panel.
  • the security mesh sheets have horizontal mesh spacings (i.e. the horizontal distance between the centres of adjacent grid wires) of 100mm or less, more preferably 90mm or less, most preferably 80mm or less. Such spacings result in openings that are too small for an attacker to easily gain a foothold, thereby providing anti-climb properties.
  • the security mesh sheets have vertical mesh spacings (i.e. the vertical distance between the centres of adjacent grid wires) of 30mm or less, preferably 20mm or less.
  • the vertical mesh spacing may be 13mm or less. Such spacings result in openings that are too small for an attacker to gain a handhold, thereby providing anti-climb properties.
  • the security mesh sheets have substantially rectangular mesh openings wherein the ratio of the long side to the short side is at least 2:1, preferably at least 3:1, most preferably at least 5:1. These features also make climbing by an attacker more difficult.
  • the security mesh sheets are formed from wire having a diameter of 3mm or greater, preferably 3.5mm or greater. Wires of such diameters vibrate under attack by a grinding tool and have sufficient strength to resist attack by tools such as bolt cutters.
  • the intermediate sheets are substantially orthogonal to the security mesh sheets. This feature maximises the transparency of the fencing, which is useful if, for example, CCTV cameras are located behind the fencing and directed outwardly at potential intruders.
  • the intermediate sheets are inclined at an angle to the security mesh sheets.
  • the angle may be in the range of 10 degrees to 80 degrees, preferably 30 degrees to 60 degrees, most preferably 40 degrees to 50 degrees.
  • the angle at which the intermediate sheets are attached to the mesh sheets is in the range of 10 degrees to 80 degrees, preferably 30 degrees to 60 degrees, most preferably 40 degrees to 50 degrees.
  • the intermediate sheets are not orthogonal to the security mesh sheets in these embodiments.
  • all of the intermediate sheets are at the same angle.
  • any transverse cross-section taken orthogonally between the two security mesh sheets intersects at least one intermediate sheet.
  • any transverse cross-section taken orthogonally between the two security mesh sheets over the majority of the length of the panel intersects at least one intermediate sheet. This further improves the anti-grind property and surprisingly does not unacceptably reduce the transparency of the fence panel.
  • the intermediate sheets may extend from a first vertical wire in one of the security mesh sheets to a second vertical wire in the other security mesh sheet that is adjacent a vertical wire opposite said first vertical wire.
  • the second vertical wire may be directly adjacent to the vertical wire opposite the first vertical wire.
  • additional vertical wires may be between said vertical wires.
  • the security fencing has a rating under ASTM F2781-10 (Table 2) of M5 or higher, preferably M10 or higher, more preferably M15 or higher.
  • the security fencing has a rating under ASTM F2781-10 (Table 2) of A5 or higher, preferably A10 or higher, more preferably A15 or higher.
  • the fence panel preferably has a visibility index of more than 40%.
  • the security fence panel of the present invention may comprise barbed wire, razor wire, razor tape or the like disposed along its upper edge region. This provides further protection from an attacker.
  • the security fence panel of the present invention may comprise one or more fastening at one or both ends thereof (i.e. the ends of the length of the fence panel), which is fixable to a supporting post.
  • the fastening is not particularly limited and may comprise any fastening known in the art, such as a fixing plate that is connected to the security mesh sheet by one or more screws or bolts and blind rivet nuts, or by welding.
  • the one or more fastening may connect the security fence panel to the supporting post at a plurality of positions along the height of both the security fence panel and the supporting post.
  • security fencing comprising at least one security fence panel as described above, further comprising supporting posts, wherein the security fence panel is secured to the supporting posts, preferably by one or more tamper-resistant fastenings.
  • a supporting post is positioned between each adjacent security fence panel.
  • the supporting posts may hold the fence panels off the ground, or the fence panels may rest on the ground.
  • the total height of the fencing may be more than 3m.
  • the supporting posts may be embedded into supporting units, such as concrete blocks.
  • the supporting posts may be intended to be buried in the surface on which the security fencing is to be positioned.
  • Barbed wire, razor wire, razor tape or the like may be connected to the upper end of the supporting posts.
  • the fastenings may connect the security fence panel to the supporting post at different points along the height and/or the depth of the security fence panel.
  • the fastenings may only be present at the ends of the security fence panel, at either end of its length.
  • the security mesh sheets may extend over at least part of opposing surfaces of the supporting post when connected together.
  • the supporting post may have a depth smaller than the depth of the security fence panel. In this embodiment, both security mesh sheets may extend over opposing surfaces of the supporting post when connected together.
  • the security fence panel may be connected to the supporting post at one or more points over its depth.
  • a cover plate may extend over the connection between the security fence panel and the supporting post. This can improve the strength of the connection, as well as preventing the attacker from trying to break said connection.
  • the supporting post may be connected to two security fence panels, which may be on opposing sides of the post.
  • a single cover plate may extend over the connection to both security fence panels.
  • the fencing may comprise any number of supporting posts or security fence panels.
  • the fencing may comprise alternating supporting posts and security fence panels, with supporting posts at either end of the fencing.
  • the fencing may comprise three or more security fence panels and four or more supporting posts.
  • the security fencing may be used as part of a perimeter fence.
  • the panels, posts and/or cover plates may be coated, optionally with a polyester.
  • the coating may have a thickness of at least 60 microns, preferably at least 100 microns. This can provide anti-corrosion protection.
  • a kit of parts for security fencing as defined above, the kit comprising a plurality of supporting posts and a plurality of security fence panels as described above.
  • the number of supporting posts may be one greater than the number of security fence panels. This means that the resulting security fencing can have a supporting post at either end thereof.
  • the kit may further comprise one or more fastenings for fixing the security fence panels to the supporting posts, as discussed above.
  • the one or more fastenings for fixing the security fence panels to the supporting posts may be integral to the security fence panels.
  • kits for creating one or more of the security fence panels discussed above may comprise an even number of security mesh sheets and a plurality of intermediate sheets, as discussed above.
  • the kit comprises a plurality of intermediate sheets per pair of security mesh sheets.
  • the kit may comprise a connecting means for connecting the intermediate sheets to the security mesh sheets.

  • FIG. 1 one section 1 of a security fencing is shown, comprising two galvanised steel tubular supporting posts 2 of rectangular transverse cross-section (as best seen in Figure 3 ) supporting two spaced apart security mesh sheets 3 and 4 which are formed of welded steel mesh and are clamped at their opposite ends to front and rear faces of the supporting posts 2 by galvanised steel fixing plates 5.
  • Rear fixing plates 5 (see Figure 5 ) secure the rear security mesh sheet 3 in the same manner as the front two fixing plates 5 secure the front security mesh sheet 4.
  • the fixing plates 5 are secured to the supporting posts 2 by tamper-resistant fastenings 7 such as bolts and blind rivet nuts for example. In other embodiments the fixing plates 5 can be secured to the supporting posts by welding for example.
  • the security mesh sheets 3 and 4 are connected by regularly spaced intermediate mesh sheets 6 (also of welded steel mesh) which extend across the space between them and impede access to the rear security mesh sheet 3 if an attack is made on the front security mesh sheet 4 by an angle grinder or other tool.
  • the spacing between the front and rear security mesh sheets 3 and 4 is suitably 100mm to 500mm i.e. greater than the radius of a commonly available angle grinder disc.

  • An intermediate mesh sheet 6 is shown in Figure 4 and has the same spacing between the wires of the mesh as the security mesh sheets 3 and 4.
  • Figure 5 shows the fencing section in perspective and it will be seen that the top face of the section is also covered by a mesh strip 34.
  • the intermediate mesh sheets 6 are attached to the vertical grid wires of the security mesh sheets 3 and 4 by spiral connectors 10, one of which is shown in Figure 5B .
  • spiral connectors 10 are threaded through the horizontal grid wires of the security mesh sheets by screwing them in from above.
  • the internal diameter of the spiral connectors 10 is suitably 22mm and the thickness of the steel wire from which the spiral connectors are formed is suitably 4mm.
  • the internal diameter of connectors 10 is large in comparison with the thickness of the vertical grid wires of the security mesh sheets 3 and 4 and intermediate mesh sheets 6 (suitably 3.6mm in each case) which results in a loose pivotal connection between each intermediate mesh sheet and the front and rear security mesh sheets with considerable movement. If a rotary tool such as an angle grinder is applied to the structure, the fencing will vibrate in an erratic manner and tend to jitter against the peripheral cutting edge of the grinder disc and may even cause the grinder disc to shatter.
  • Figure 6 shows the horizontal and vertical galvanised steel grid wires 8 and 9 of the security mesh of one of the security mesh sheets 3 or 4 in more detail.

  • Figures 7, 7A and 8 show a second embodiment of the present invention.
  • Figure 7 shows a security fencing panel identical to that of Figures 1 to 6 except that the intermediate steel mesh sheets 60 are inclined at an angle ⁇ to the front and rear security mesh sheets 4 and 3 in plan view, as best seen in Figures 7a and 8 .
  • the depth of the fence panel i.e. the distance between the two security mesh sheets 3 and 4) is the same as in the first embodiment and so the intermediate sheets 6 are wider than that shown in Figure 4 .
  • Angle ⁇ is suitably in the range of 10 degrees to 80 degrees, preferably 30 degrees to 60 degrees, most preferably 40 degrees to 50 degrees and in the embodiment of Figures 7 to 8 is 45 degrees.
  • the widths and spacing of the intermediate mesh sheets 60 are such that they extend over the entire width of the security fencing panel with no gaps between them in the width direction.
  • any projectile directed at the fencing panel will tend either to glance off the front security mesh sheet 4 or, if it is directed orthogonally at the fencing panel will tend to be deflected by one of the intermediate mesh sheets 60 even if it penetrates the front security mesh sheet.
  • a security fencing panel construction in which the intermediate sheets are at an angle to the security mesh sheets will tend to be more opaque than that in which the intermediate sheets are orthogonal to the security mesh sheets, which will be advantageous in some applications.
  • the increase in opacity is not as great as may be expected, as the resulting security fence panel may still be at least partially transparent.
  • the thickness of the steel wires used in the security mesh sheets may be increased to 4mm or greater, for example 5.6mm. If it is necessary to limit the weight of the construction, the spacing of the wires may be increased, for example to 20mm or greater. The thickness of the steel wires may also be reduced in order to reduce the weight of the security fence panel.
  • Figures 9, 10 and 11 show a third embodiment of the present invention. Referring to Figure 9 , the supporting posts 2 are embedded in concrete blocks 41 and are connected by a ground-level concrete barrier 42 ( Figure 10 ).
  • the concrete blocks may have a height of more than 0.5m, preferably more than 0.6m.
  • the front security mesh sheet 40 has a height H1 of more than 3m which is significantly greater than that of the rear security mesh sheet 3.
  • H2 above ground level G
  • H2 is suitably more than 2m in this embodiment.
  • the supporting posts 2 carry upper extension portions on which is mounted a coil 12 of razor wire, backed by three horizontal rows 11 of razor tape or barbed wire to deter climbers.
