EP3274971B1 - Lattice mat for guiding a signal cable - Google Patents

Description

The invention relates to a grid mat with tubes for guiding a signal cable having the features of the preamble of claim 1.

Such grid mats are used in particular for alarm-secured security fencing, also called detection fences, for outdoor security. The incorporated signal cables should detect intrusion attempts and report to an alarm center. However, such grid mats can also be used for securing shafts, in particular sewage shafts in the power plant sector, in particular in nuclear power plants, in the security-relevant factory environment and for securing windows or other recesses and openings.

Grid bars mats are known in which horizontal and vertical fill bars intersect and are welded together at the crossing points. At least a subset of the filler rods may be formed hollow inside, so be tubular, so that a signal cable can be fed. These signal cables can detect a severing of the filler rods or, depending on the design, also a strong deformation. Such mesh mats have basically proven.

The FR 2 546 427 A1 discloses a lattice mat suitable for signal detection, which is formed by longitudinal and transverse bars, which are intertwined with each other. Parts of the rods are formed as tubes, in which a signal cable is retracted. It is further provided that in the edge regions, the signal cable is led out in a loop and then proceeds in one of the adjacent longitudinal or transverse bars. An adaptation to terrain inclinations is ensured with the thus interwoven longitudinal and transverse bars by the partial deformability of the mesh mat fabric with warp and weft threads. A diamond-shaped contour can be obtained by displacing the parallel, in particular vertical, edges from a lattice mat field, which is initially designed as a rectangle. This allows the adaptation of a fence panel to the slope of the terrain.

The EP 2 428 941 A1 discloses the provision of frames on at least three of the edge portions of such a grid mat to provide an enclosure of the grid mat, suggesting receiving spaces for the loops of the signal cables in the periphery. The corresponding connection of the tube ends of the grid mat with the there proposed frame profiles limits the possible uses of the grid mat and is also consuming and expensive. Although it allows a largely flexible guidance of a signal cable through several of the longitudinal and transverse tubes of a grid mat, whereby a meandering guidance of a signal cable is made possible, which makes it difficult for an attacker to cut a suitable for a passage hole in the grid mesh without triggering an alarm but displaces the critical signal cable sections, especially in longitudinal and transverse tubes, which remain separated at the crossing points, in particular with their cable ducts, in the edge regions of the grid mat, which are prone to interference and primarily the attachment of the grid mat to fence posts or the connection serve with a climb protection or creep protection. Also the EP 0 072 085 A1 shows such a grid mat, in which a cable guide through several of the tubes of the grid mat is achieved by the cable is guided in the edge region of the grid mat outside of tubes, wherein the cable guide is covered in this edge region by a hollow frame profile.

It is therefore an object of the present invention to provide a grid mat, which is designed for the guidance of one or more signal cable on one or more shielded paths, without having to rely on the use of frame profiles. This object is achieved by the further features of claim 1 after the license plate. An alarm-secured security fence according to the invention is proposed by claims 13 and 15.

Further developments of the invention are defined by the dependent claims. The grid mat according to the invention is designed and / or has means that a signal cable on at least one path that runs between the entrance to the grid mat and the exit from the grid mat by more than one tube, in particular by a plurality of tubes, and thereby only in the interior of the grid mat may run partially outside of tubes, can be passed through the grid mat.

According to embodiments arcuate tubes are provided on one or more of the edges of the grid mat in order to possibly lead there a retracted signal cable. Characterized in that the grid mat is formed so that only in the interior of the grid mat and / or the substantially vertical edges of the grid mat, a signal cable runs partially outside of tubes to between different tubes, in particular the substantially vertical or transverse to the longitudinal direction of the grid mat tubes To change, any signal cable courses are provided within the grid mat by the inventive design of the grid mat itself and are For example, not dependent on an education of the interface to fasteners.

Preferably, the grid mat is formed so that a signal cable can be guided on a plurality of such paths through the grid mats, without extending in particular at the horizontal edges of the grid mat outside of tubes. This makes it possible, if necessary, to provide a highly meander-shaped signal cable guide within the grid mat. This is not mandatory. According to the invention, an alarm-secured security fence can also provide lattice mats entirely without the guidance of signal cables. Only the externally visible, inventive design of the grid mat can bring about the effect that potential attackers expect the leadership of signal cables and therefore refrain from an intervention or a Durchstiegsversuch.

According to the invention, the grid mat, in particular in its interior, has an area in which a part of the tubes is interrupted, so that the path of a signal cable emerging in the area could be continued in more than one way. The area is covered by a flat element, which may be part of an impact and / or drive-through protection, covered by at least one side of the grid mat.

Furthermore, a protective and / or alarm wire which is preferably stretched over at least one dimension of the flat element and which is preferably designed as a steel cable can be arranged behind the planar element, so that it can not be seen from the attack side or outside of the grid mat. The area with broken tubes can be completed from the other side of the grid mat by another flat element, or component, which can be designed as a lid, so that even through the use of small mirrors or the like no information about the guidance of signal cables in the area can be won.

According to a further preferred embodiment arcuate tubes are provided at the edges of the grid mat, which can serve to guide a signal cable. In this case, the arcuate tubes can directly connect adjacent tube ends or skip individual tube ends, which, for example, does not require a signal cable to be routed in each vertical or transverse tube. In order to facilitate a plurality of signal cable guides, bilateral connections can be made through arcuate tubes containing a Y-shaped tube section starting from one tube end to tube ends adjacent to both sides to lead. In conjunction with the possibility of returning the signal cable in a tube, this significantly increases the ambiguity of possible signal cable guides.

The intersecting tubes of the grid mat may have a wave-like course and be woven together in a textile-like manner, which, as described above, in particular makes possible an advantageous terrain inclination adjustment. Alternatively, the intersecting tubes may be welded together at the crossing points. Signal cables may be loosely inserted into the tubes or adhered by adhesive preferably injected into the tubes. According to embodiments, the tubes have an oval cross-section and / or have a plurality of chambers, wherein the grid mat can be processed, for example, in a safety fence so that signal cables are guided in a chamber or sub-chamber against the expected gravitational force in the tubes. Such designs can lead to the triggering of an alarm even with a careful opening of tubes by means of saws, flex or side cutters from the supposedly safe side.

The intersecting tubes of the grid mat do not have to be substantially vertical and horizontal, but according to embodiments can also extend diagonally to the edges of the grid mat. A grid mat according to the invention may further be formed in part of filler rods and be formed only to a part of tubes for the possible guidance of a signal cable. According to further embodiments, the lattice mat may be angled parallel to an edge for integral overshoot protection, or an overhang protector with angled cantilevers may be applied at a point in front of the upper edge of the lattice mat.

According to another embodiment, an alarm-secured security fence with a grid mat according to the invention is provided with at least one arcuate tube at the lower edge of the grid mat, which may be provided as part of a ground anchor and / or a gangway protection. This provides a direct connection of the grid mat with the ground anchor and / or a drive-through protection.

An alarm-secured security fence according to the invention has, according to an advantageous embodiment, a grid mat, wherein the grid mat is at least partially formed from tubes and at least one signal cable is guided through the grid mat. The tubes are interrupted in an inner region of the grid mat and the area is covered with a planar element at least on one of the two surfaces of the grid mat. Thereby, the area with the interruptions of the tubes, and in particular a signal cable carried in the area, at least from one side of the security fence not be seen. Preferably, the area is also covered by the other of the two surfaces of the grid mat, so that the area without intervention on the flat cover elements can be viewed from either side of the security fence.

According to advantageous developments, an alarm-secured security fence may further comprise an LED illumination for illumination, signaling and / or deterrence / defense. According to further embodiments, a color coding system is arranged to spray in response to an attack on the security fence marking color for identifying a person causing the intervention and / or an intervention causing object. Still other embodiments further include a bus system having bus elements connected to an evaluation unit via a signal cable routed through one or more grid mats. The bus elements send regularly, in particular periodically, feedback signals to the evaluation unit, as long as their connection to the evaluation unit is not interrupted by means of the signal cable. According to an advantageous development, a video surveillance system is set up such that a targeted video surveillance of the intervention location can be carried out in conjunction with a procedure recognized by a signal cable carried in the grid mats. With outdoor coverage lengths of several kilometers, widespread, high-resolution monitoring, capture and documentation using video cameras is difficult. However, it is possible, with knowledge of a relevant location area with few cameras and targeted zooming in to make a much better video capture of the relevant operations on the security fence. According to this embodiment, the provision of a video camera is sufficient only about every 100 to 400 meters.

By way of example, modular fence posts are also described which are particularly advantageous for the alarm security fencing described above. The combination of a crash protection, which also serves the opaque covering a portion of the grid mat with broken tubes, with a reinforced modular fence post or a modular fence post from a ground anchor and fixed aluminum post, is advantageous. This is especially true for the provision of a ride-through protection with steel cable, where a stable attachment of the drive-through protection and / or steel rope is supported on the fence post by the providence of a reinforcement of the fence post by means of reinforcing element or beyond the area of the drive-through fuse and its fastening devices also reaching ground anchor.

A textile-like meshed lattice mat 1 according to the prior art is in Figure 1A displayed. FIG. 1B illustrates the described providence of a frame 21 for such a grid mat 1 in order to make a signal cable guide outside of tube ends 13 of the grid mat 1 in a hidden manner.

FIG. 2 Figure 11 shows an exemplary embodiment of the invention in which a grid mat 11 is formed of intersecting tubes 3 and has arcuate tubes 24 at the lower edge 22a and upper edge 22b. The arcuate tubes 24 may be provided at all tube ends 25 at the lower edge 22 a and the upper edge 22 b of the grid mat 11. The arcuate tubes 24 are offset between the upper edge 22b and the lower edge 22a about a tube end 25, so that a signal cable through all the vertical tubes 3 of the grid mat 11 can be guided in a meandering manner through the grid mat 11. From the entrance E into the grid mat 11 to the exit A from the grid mat 11, exactly one path for a signal cable is defined in the illustrated embodiment, from a trivial passage through only one tube, the longitudinal tube beginning at the entrance E, from one side to the other the grid mat is apart. Instead of tubes 3, filler rods can also be used horizontally or in the longitudinal direction of the grid mat, since in this embodiment the signal cable guidance is advantageously effected by the vertical tubes 3 arranged in the transverse direction. However, there are also provided embodiments in which the signal cable is mainly done by horizontal and in particular by both horizontal and vertical tubes.

At the in Fig. 2 an embodiment, an attacker expected the leadership of a signal cable in all of the vertical tubes 3. This can unfold considerable deterrent effect against a Durchsteigeversuch. For this purpose, it is not necessary to actually feed a signal cable into the grid mat 11. According to the invention, electrical and / or optical signal cables can be used as signal cables in this as well as in all of the embodiments described below, with an alarm not only when contacting or severing a signal cable, but also during a corresponding deflection and / or deformation of the tubes 3 or 24 the grid mat 11 can be triggered. If a signal cable is drawn into the lattice mat 11, a nationwide providence of signal cable leading tubes 3 is present at a standard tube spacing of 5 to 10 centimeters. A passage through the grid mat 11 is then not possible without cutting signal cables leading tubes 3.

FIG. 3A shows an exemplary embodiment with broken in an inner region 5 of the grid mat 11 tubes 3. In the illustration, two vertical tubes 3 and a horizontal tube 3 in the area 5 are interrupted. But it can also be interrupted only one or more vertical tubes 3 or only one or more horizontal tubes 3. A signal cable 4 can be performed accordingly in leaving any of the broken tubes 3 in any way in other broken tubes 3. This can include a return of a signal cable, in particular until shortly before a bent or crushed at the upper or lower edge 22b or 22a of the grid mat 11 tube end, whereby a high area coverage can be achieved by the signal cable 4, without the signal cable 4 in the corresponding 3 tubes from the tube ends 25 would have to be performed out. A recirculated signal cable 4a is in FIG. 3A shown in two places. A signal cable 4a can be bent in particular for the purpose of the return and introduced in an already bent form in a tube 3 substantially to its tube end 25.

To disguise the presence of such a region 5 with broken tubes 3, planar elements or components 6 and / or 12 may be provided, wherein a planar element 6 is provided for the region 5 for covering one side of the grid mat and also a planar element 12 can enter from the other side of the grid mat. The sheet-like elements 6 and 12 need not be limited essentially to the area 5 with interrupted tubes 3, but may, for example, extend over a dimension of the grid mat in the horizontal, diagonal or vertical direction. According to one embodiment, the sheet-like elements 6 and 12 are part of a bumper or drive-through protection 7. An impact protection 7 can increase the stability of the grid mat 11 with respect to forcibly induced deformations. He may also serve to deter attempts to break through a grid mat 11. When using the grid mat 11 as part of a safety fence, a drive-through protection 7 may be provided, in particular at a height which covers the impact area of a vehicle aiming for a breakthrough. Due to the recognizable primary function of such impact or collision protection 7, the provision of interrupted tubes 3 behind the sheet-like elements 6 and / or 12 of such impact or collision protection is unexpected. Accordingly, in this embodiment, dispensing with connecting elements at the lower edge 22a or upper edge 22b and directly viewable areas on the vertical edges of the grid mat, which indicate that there are no signal cable loops, or of suitable covers, the cable guide yet present obscured at the vertical edges, and providing a cover of the entrance E and exit A of a signal cable, the implementation of the Signal cables 4 are completely obscured by the grid mat 11 from possible attackers. The potential attacker sees only a grid mat 11 with an impact protection or drive-through protection 7 and is reinforced, for example, in particular by bevelled, crushed or otherwise closed tube ends 25 at the edges 22 of the grid mat 11 in his assessment that the grid mat 11 is not alarm-secured. Accordingly, with a correspondingly configured grid mat 11, a high detection efficiency can be achieved, since a pass-through test without the expectation of corresponding signal cable guides will take place carelessly and an alarm is correspondingly easily triggered by activation of a signal cable 4.

An impact protection or drive-through protection 7 can optionally have a tensioned protection wire against passage or puncture and / or an alarm wire 8, which are clamped or stretched over the length of the passage protection 7 or concealed by it. The protective and / or alarm wire 8 may, according to one embodiment, also be covered only partially by the flat elements 6 and / or 12 of the impact protection or drive-through protection 7. The wire 8 is preferably formed from steel cord. In an embodiment with alarm wire, a detection of deviations of a quiescent current or changed properties of an optical waveguide (LWL) can take place. Furthermore, an expansion can be detected by measurement or a tension sensor can be coupled to the wire 8, in particular a steel cable.

FIG. 3B shows an exemplary embodiment for the coverage of a region 5 by means of flat elements 6 and 12. In the figure, a cross section through the grid mat 11 with tubes 3 is shown. The planar element 6 may have a U-profile 9. The sheet-like element 12 can enter as a closure part or cover on the other side of the grid mat 11 a positive connection with the sheet-like element 6. At least one leg 10 of the U-profile 9 of the sheet-like element 6 or alternatively the sheet-like element 12 is preferably formed comb-like, so that the sheet-like element 6 can engage with its U-profile 9 via legs 10 in the grid mat 11. Advantageously, further elements, in particular strips on the leg 10 are provided, which accomplish an improved stable engagement in the grid mat 11. This can be done by plugging in and then moving in the grid mat level. As for the embodiment of FIG. 3A described, the covering sheet-like elements 6 and 12 may be part of an impact protection or drive-through protection 7. Optionally, a wire 8, in particular an alarm or safety wire is provided, which is not shown in the figure as well as the vertical tubes 3.

The above to the Figures 2 and 3 described embodiments may be combined in another exemplary embodiment. FIG. 4 shows by way of example a schematic representation of such an embodiment, in which an area 5 with interrupted tubes 3 additionally provides arcuate tubes 24 and / or 24a. The region 5 is covered in this embodiment with a planar element 6, which may be part of an impact protection or drive-through protection 7 and optionally may have a wire 8 as described above. The arcuate tubes 24 may connect adjacent tube ends 25. Arcuate tubes 24a may connect one tube end 25 to a second tube end 25 thereafter.

By combining the arcuate tubes 24 and / or 24a with a discontinuous area 5 and a planar element 6, various types of signal cable guide paths can be made possible, which need not necessarily be used when using the grid mat 11. In this case, the combined provision of the tube interruptions in one or more inner regions 5 of the grid mat 11 with arcuate tubes at upper and / or lower edges 22 of the grid mat 11 increases the ambiguity of possible signal cable design. In an advantageous embodiment, the arcuate tubes 24 and / or 24a serve only to deceive possible attackers. The actual implementation of different signal cable paths is carried out by the area 5 with the broken tubes, the arcuate tubes 24 and / or 24a pretend only the leadership of a signal cable 4. This can ultimately prevent a potential attacker, especially when using multiple, according to the embodiments described here differently ausgestalteter lattice mats 11 to ever make a pass attempt, since the actual implementation of signal cables in the grid mats even with deep observation of a free-fall security system with such a multi-shaped alarm-secured security fence not apparent.

Fig. 4 illustrates a possible path of a signal cable 4 with recirculated sections 4a. As can be seen, the signal cable 4 can be guided on a variety of other paths through the grid mat without changing the entry and exit from the grid mat 11. Furthermore, the signal cable 4 at the vertical edges or in the inner region 5 in a horizontal tube 3, preferably also with recirculation, are performed.

FIG. 5 shows an embodiment of arcuate tubes 24b, which significantly increases the ambiguity of a signal cable guide, particularly in connection with feedback of signal cables. At the tube end 25a, a Y-shaped tube section 26 connects, which connects to tube ends 25b and 25c by means of the arcuate tubes 24b and connects in this way three tubes 3 together. A signal cable 4, which approaches the tube end 25a in the middle tube 3 from below, can be continued in a variety of ways. For example, it may be recirculated prior to reaching the tube end 25a and may extend approximately back to its starting point in the middle tube 3, via the arcuate tubes 24b into the tube to the left of the middle tube 3, or alternatively into the tube to the right of the middle tube become. There again, the signal cable 4 can be returned by return shortly before or after the tube end 25b or 25c back into the arcuate tube 24b. For example, this allows the guidance of a signal cable exclusively along an edge 22, in particular the lower edge 22a or the upper edge 22b of a grid mat 11 according to the invention for at least individual grid mats 11, whereas the provision of further arcuate tubes 24, 24a and / or 24b at the edges , in particular the lower edge 22a or the upper edge 22b speaks for a meandering guidance of a signal cable in the grid mat 11 and unfolds corresponding deterrent effect.

According to one embodiment, instead of the Y-shaped tube sections 26 and the arcuate tubes 24b, a continuous tube piece can be inserted along the edge of the grid mat into which one or more tube ends 25 are inserted. The tube ends 25 can be additionally glued to the pipe section. Also in this exemplary embodiment, the signal cable 4 can be continued in any way to the left or right.

FIG. 6 shows an exemplary embodiment of an alarm-secured security fence with two grid mats 11. The grid mats 11 are attached to fence posts 28. The attachment is preferably on the inside of the security fence and the fence post 28th FIG. 7 shows on the right side a view of the inside of a corresponding alarm-secured security fence, in which a cover strip 34, the attachment of the grid mats 11 to the fence posts 28 and thus in particular an entrance E and an outlet A of a signal cable in the grid mat, but also possible signal cable between different horizontal tubes 3 protects against unauthorized access.

As in FIG. 6 is shown, the grid mat 11 may have an area which is formed either in continuous continuation in the plane of the grid mat 11 as part of a Übersteigschutzes 31 or instead for this purpose parallel to an upper edge 22b of the grid mat 11 kinked as an angled portion 27 of Grid mat 11 is continued. An escrow 31 may, according to embodiments of the Invention additionally comprises an arm 32 angled portion which lies opposite the angled portion 27 of the grid mat. By means of the boom 32 barbed wires or other wires that make it difficult to exceed the alarm-secured security fence are stretched. The cantilevers 32 may be formed as shear-off arms which have an alarm wire shearing off when loaded or, in the event of shearing, activate a sensor which is preferably provided with an address and is used for detecting a shearing. Moreover, shearing makes it difficult to exceed the safety fence.

It is advantageous to stably form a lattice mat element for a climb-over protector 31 either by a continuous grid mat 11 or a solid, angled section 27 of the grid mat 11 and not to apply a separate grid mat element in an angled manner to the grid mat 11. The latter would be very vulnerable, especially when trained as a shearing boom for snow loads, because in relation to a boom counterpart with only tensioned wires an imbalance of the load with snow masses would result. This could lead to faulty shearing. t.

An advantageous embodiment provides both on the inside and on the outer or attacker side a solid, angled grid mat element to compensate for the burden of snow loads. In an alternative embodiment, a continuous, non-angled grid mat to the outside of a part of the overpass protection 31, which is supplemented on the inside with preferably shearing arms 32 with wires, in particular barbed wires between the arms, wherein the arms 32 on the inside substantially in one 45-degree angle to the grid mat 11 are arranged, whereas the grid mat is continued in the area of the over-shoot protection 31 substantially at an angle of 0 degrees.

According to further embodiments, cantilever devices and non-angled or angled lattice mat sections, as a continuation and kinked or beveled portion of the grid mat 11 or as a separate grid mat element, be combined for further safety devices, with angled on both sides devices, or on one side only an angled device for Use can come.

An alarm-secured security fence 2 may further include a crawl protection 30, which may be combined with a mower guard. A Unterkriechschutz 30 can also take over the function of a Untergrabschutzes. The Unterkriechschutz 30 can in a Ground channel or trench to be anchored in particular by pouring concrete. Anchoring the safety fence in the ground is preferably concentrated or restricted to areas around the fence posts 28 that are typically hammered into the ground.

An alarm-secured security fence 2 according to the FIGS. 6 and 7 also has a drive-through protection 7 with planar elements 6 and / or 12 for the advantageous covering of a FIG. 3A and 4 described inner area 5 with broken tubes 3 of the grid mat 11. In this case, the planar element 6 from the front, the outside and / or the planar element 12 engage from the inside with a comb-like leg 10 of a U-profile in the grid mat 11 and adjacent with its profile on a side or end face of the fence posts 28 or advantageous also engage the fence post in the fence post 28 by means of, for example, staples or screws attached grid mat 11.

In the in the FIGS. 6 and 7 illustrated embodiment, the grid mat on the upper 22b and lower edge 22a no arcuate tubes 24 at the tube ends 25 on. Signal cables 4 may be routed in at least some of the tubes 3 substantially to a tube end 25 which may be bevelled, chipped or squeezed and optionally also sealed. Also in horizontal tubes a return of a signal cable in addition to a continuation in particular another horizontal tube 3 is possible.

FIG. 8 shows an exemplary embodiment for an alarm-secured security fence with grid mats 11, fence posts 28 and overhang protection 31 with brackets 32. Between the fence posts 28 a crawler 30 is provided. At the lower edge 22a of the grid mats 11 arcuate tubes 24 are provided for guiding a signal cable, which as described above according to embodiments does not necessarily have a signal cable in the tubes 3 and 24 must be performed. The fence posts 28 can be anchored by pouring a corresponding trench, which is for example 50 centimeters deep and 10 centimeters wide, with concrete stable in the ground. In this case, the Unterkriechschutz 30 may be anchored with. One or more of the arcuate tubes 24 may also be potted or provided with the Betonverguss by Providence corresponding clips or correspondingly long version of the bow legs. A corresponding ground anchor 29 is shown schematically in the drawing and can be configured in various ways. This type of anchoring is particularly advantageous because, for example, only a corresponding configuration of the tubes 24, in particular the length of the legs of the arcuate tubes 24 is required to achieve a stable connection of the grid mat 11 with the anchoring in the ground.

Alternatively, by way of example, a steel brace can make the connection between a tube 24 anchored in the ground.

FIG. 9 shows an exemplary embodiment of the alarm-secured security fence 2 in plan view. A signal cable laying system 33 is provided for the orderly routing of the signal cables in the floor and the division of the signal cable total length into individual sectors according to further embodiments. In this case, for each sector, which may comprise one to several complete grid mats 11 or may also be provided for corresponding partial lengths of the signal cable, in each case bus elements may be provided for preferably serial communication with an evaluation unit. In this way, by appropriate feedback of the bus elements and in particular the absence of feedback from bus elements above a certain sector, an alarm detected by means of signal cable can be located. Individual bus elements can send their address or an identification code to a local or central evaluation unit, for example in the form of a periodic sign of life or ping.

In the case of a fault or disconnection of the cable connection between, for example, a bus element in sector 3 and a bus element in sector 4, the bus elements 1 to 3 continue to send their life signals to an evaluation unit, whereas from bus element 4 no signal is fed back. Accordingly, the interference with the security fence 2 can be localized to the area between sectors 3 and 4, and a video surveillance system can be aligned to this area to carry out an improved video capture and / or video analysis of an event. This allows the economical provision of CCTV elements along extensive security fencing. Video cameras with powerful magnifying optics can then zoom sufficiently close to, for example, also 100 or 200 meters away fence sections zoom.

Alternatively or additionally, bus elements can be provided which actively monitor in each case a part of the grid mats and preferably also their shearing arms and trigger an alarm for a corresponding sector in the event of a fault.

In the following, particularly advantageous fence posts for the grid mats 11 according to the invention and alarm-secured safety fences 2 are described.

Figure 10A shows an exemplary embodiment of a fence post 28, further comprising elements of the above-described overshoot protection 31, such as preferably shearing boom 32 and an angled portion 27 of the grid mat 44 are shown. The grid mat 44 is advantageously attached to the inside of the fence post 28. A Untergrabschutz 30 with optionally a Mähschutz 35 can fence posts between 28th be attached. Figure 10A further shows a trench 36, which may preferably be poured with concrete. The fence post 28 is hammered or screwed into the ground 42, for example.

FIG. 10B shows an exemplary modular fence post 40. The modular fence post 40 has a ground anchor 41 and a post 43, preferably formed of aluminum. The ground anchor 41 serves to anchor the fence post 40 in the ground 42 and is typically hammered. For a security fence 2, the depth of impact into the ground 42 may be about one to two meters. The ground anchor 41 preferably has a total length of two and a half to three meters and protrudes when embarked, for example, a half to a meter above the ground 42 addition. The post 43 is applied to the ground anchor 41 and fixed. Advantageously, the post 43 extends in the built-in security fence to below the surface, so that both ground anchor 41 and post 43 can be cast in a trench 36 with concrete. The post 43 extends from the ground surface, for example, two to three meters upwards. A pass-through protection 49 is mounted with fasteners 48 on the post 43 of the modular fence post 40. The ground anchor 41 extends in the installed state, preferably up to a height above the fastening means 48, so that the reinforcing effect by the inner ground anchor 41 on the post formed for example of aluminum 43 stabilizing the drive-through 49 with preferably a stable wire 8 as described above causes.

FIG. 10C shows an exemplary embodiment in which a modular fence post 40 after FIG. 10B a triangular post 43 which is applied to a T-shaped ground anchor 41. Shown is a continuous at the fence posts 40 grid mat 11. This may be the case with elongated grid mats 11, for example, every second fence post 40. On the other fence posts 40, however, in each case two grid mats 11 may end and be concealed in the region of the connection to the fence posts 40 by one or more vertical cover strips 34. The tubes 3 of the grid mat

For example, they can be easily attached to the fence post 40 by staples, and one or more cover strips 34 can shield the ends of the tubes 3 and thus a possible cable routing between the horizontal tubes 3.

Figure 10D shows an exemplary embodiment in which a modular fence post 45 has a post 47 for anchoring in the ground 42 and for attaching a grid mat 44. The modular fence post 45 further comprises a reinforcing element 46, which in particular in the area around the bottom surface for reinforcing the post 47th is provided. The reinforcing element 46 can be arranged inside the post 47, for example as an inner tube, on or about the post 47 and is provided in particular in a statically relevant height range of the fence post 45 in order to reinforce the post 47 in particular against lateral forces. Advantageously, the fence post 45 with post 47 and reinforcing element 46 is modular, so that the reinforcing element 46 can be mounted after insertion, in particular wrapping or screwing the post 47. It is particularly advantageous to design the reinforcing element 46 so that it extends over an area of anchoring in a trench in the floor 42, at least a part thereof, and above the floor surface up to a height that attaches to a drive-through protection 49 with fastening devices 48 on post 47 is sufficient so that force effects on the pass-through protection 49, which are transmitted to the fence post 45, can be intercepted improved by the reinforcement of the post 47 with the reinforcing element 46.

A reinforcing element 46 may, for example, have an overall length of 80 centimeters. Installed in the modular fence post 45, the reinforcing element may extend to a range of 10 centimeters below the floor surface to above a steel wire of a ride-through guard 49 with corresponding fasteners 48. Alternatively, the reinforcement member 46 may extend downwardly from a height above the fasteners 48 of a ride-through protection 49 and / or a wire of the ride-through protection 49 to the top of the hammered post 47 after the reinforcement member 46 has been inserted into the post 47.
