Description

OBJECT OF THE INVENTION

The following Utility Model, as expressed in the formulation of the present descriptive specification, refers to an anti-intrusion fencing, which can be erected especially for use as protection for sites where there is traffic and long routes that require a certain level of security, in such a way that the first aim is to produce a fencing which is easy and quick to mount at low cost.
Another aim of the fencing is for the interlinked wire meshes that form it to have a conductor wire, which may or may not be connected in the mounting of the same, which is fitted into a tubular element, like wires, it being concealed and not being possible to notice, in such a way that upon being connected, when it comes to erecting the fencing, it would provide evidence of cutting or vandalism by impact, which generates an alarm at the control centre.

APPLICATION FIELD

In the present specification, an anti-intrusion fencing is described, applied and erected especially for use as protection of long perimeter routes, and sites where there is traffic, which should have a certain level of security.

BACKGROUND OF THE INVENTION

Traditionally, various fencing methods have been used to protect certain precincts, in such a way that of the structural systems used, in those which physical presence is not required, we might consider that which is formed by a wall or greater crown wall topped with a barbed wire, without any kind of added element.
Considering various fencings which aim to prevent access to certain areas, we might consider that system formed by a pair of fencings, parallel to one another and installed along the entire length of the area to be protected, these fencings being formed by the use of support profiles, between which a metal network is arranged.
Likewise, in a first embodiment, the support profiles may be topped with, at least, an inclined stretch in their upper portion, various rows of barbed wire being arranged between these inclined stretches.
In a second practical embodiment, the support profiles may be topped according to two inclined stretches, at both sides, it being possible for various rows of barbed wire to remain between them. In addition, a spiral roll of barbed wire may be placed in their upper central portion between the two inclined stretches, which define a "V" shaped space.
In this way, stairs or other similar elements may be placed on the barbed wires arranged between the inclined stretches, on those which the support profiles top, with the aim of being able to access the upper portion of the fencing, by means of fitting some kind of protection elements onto the barbed wires, such as simple cardboard boxes, in order to avoid getting cut and be able to pass over the fencing.
Equally, it is possible to arrange one or various spiral rolls of barbed wire on the internal face of the first protective fencing, it being possible to arrange these rolls in different ways.
The barbed wires that form the spiral roll may have different blade forms, which is disadvantageous in that this could result in different levels of injury for those people who try to pass the fencing.
This formation is disadvantageous in that, in addition to not being infallible, when attempts are made to "overcome" the protective fencing described, those who try to do so may suffer significant accidents, mainly as a result of severe cuts.
Likewise, it is possible to cite utility model document ES 1 066 931 , in which a "Dispositivo de vallado protector" [protective fencing device] is described, this device being formed by a plurality of posts anchored to the ground, a mesh defined by a rectangular steel wire framework being mounted between them and a plurality of angular plates, mounted in the upper portion of the mesh by one of their wings, their other wing having a small hollow lug in orthogonal position, in addition to a towrope which passes through the openings in the lugs of the angular plates and a "U" profiled guide, joined to the mesh, between posts, which houses a sensor defined by a transducer cable, which houses a fiber optic cable inside it.
Equally, we might consider document ES 1 068 493 , in which a "vallado anti-intrusión" [anti-intrusion fence] is described, in such a way that at least one conductor wire is built into the framework of the modules, in a horizontal position, this conductor wire defining a pre-sensor detector for cuts in the framework and/or, in the upper portion, an anti-jump sensor is built into the modules forming the fencing, along the entire length thereof, defined by a pair of profiles, which are hinged together and held in position by a plurality of springs, a first profile being joined to the fence and it being possible for the second profile to rotate relative to both sides of the plane vertical to the rotation axis, both profiles having a plurality of sensors built into them for detecting rotation in the second profile.
Finally, we might consider document ES 1 068 893 in which a "valla anti-intrusión" [anti-intrusion fence] is described, which has a number of "U" profiled posts anchored to the ground, one side of the frame that the two adjacent modules that meet on their core being backed against and attached to it, the fastening screws inside its core being inaccessible from the fencing area.
Moreover, the profile defining the sides of the frame forming the modules has a generally quadrangular profile with a protrusion coming out of its front face towards the inside of the frame formed.

DESCRIPTION OF THE INVENTION

In the present specification, an anti-intrusion fencing is described that can be erected especially for use as protection for sites where there is traffic and long routes which require a certain level of security, this fencing being based on a plurality of posts anchored to the ground, between which wire meshes are arranged with the aim of being able to detect any attempt to gain access by means of cutting the wire mesh quickly, safely and reliably, in such a way that the anti-intrusion fencing is formed by:

A plurality of interlinked wire meshes, which incorporate, at least, a tubular element, in horizontal position, with a conductor wire inside, concealed amongst the actual wires,
A plurality of posts defined by a "U" section profile, with divergent wings ending in respective flanges towards the outside and,
A plurality of closing cover bodies over the flanges of the profile sections forming the plurality of posts on which the plurality of wire meshes converge in order to be fastened.

Since the electric conductor wire is located inside the corresponding tubular element, like a wire, it is not possible to observe it or even know that it exists. Therefore, in the event of an intrusion by means of cutting the wire mesh in order to access the restricted area, the intruder would not be capable of detecting the existence of the alarm conductor wire and upon cutting it, would be detected, the corresponding warning being sent.
Furthermore, the plurality of electrically welded flat wire meshes with the incorporation of, at least, one tubular element with a conductor wire inside, concealed in the wire framework is not contained within a perimeter frame.
Moreover, the plurality of posts, amongst which the plurality of interlinked wire meshes are located, are defined by a "U" section profile of divergent wings ending in respective flanges towards the outside.
In a second practical embodiment of the invention, the plurality of wire meshes with, at least, one tubular element with a conductor wire inside it, concealed in the wire framework, may have a series of "V" shaped protrusions, of differing heights, which provide rigidity.
Likewise, according to this second practical embodiment of the invention, the plurality of posts, amongst which the plurality of interlinked wire meshes are located, are defined by a "U" section profile of divergent wings ending in respective flanges towards the outside, a series of general "V" shaped cuts being arranged along the length of both wings and flanges of the profile forming the posts.
In this way, in a first practical embodiment in the mounting of the fencing, the sides of the flat wire meshes converge on respective posts, located on the flanges on which the wings of the general "U" shaped profiles of divergent wings end and being fixed by means of corresponding cover bodies attached to said flanges.
In the second practical embodiment of the invention, when mounting the fencing, the sides of the wire meshes with a series of "V" shaped protrusions converge on respective posts and remain on the flanges on which the divergent wings of the general "U" shaped profiles end, which are provided with a series of general "V" shaped cuts along the length of the same, the "V" shaped protrusions of the wire meshes coinciding with said series of "V" shaped cuts made along the length of its wings, it being fastened by means of corresponding cover bodies fastened to said flanges.
This gives rise to an anti-intrusion fencing, which, according to two practical embodiment variations, is erected in a quick, rapid and simple way at a low economic cost, which is also highly reliable.
Moreover, the interlinked wire meshes forming the anti-intrusion fencing have a sensor which may or may not be connected when mounting the same, in such a way that if it is connected it generates an alarm upon cutting or vandalism impact being detected, with the advantage that said provision of evidence cannot be detected, meaning an intruder could not detect it by examining the same.
In order to complement the description that follows and with the aim of facilitating a better understanding of the invention characteristics, the present descriptive specification is accompanied by a set of plans, the figures contained therein providing a non-limiting example of the invention's most characteristic details.

DESCRIPTION OF A PREFERRED EMBODIMENT

In view of the figures mentioned above and in accordance with the numbering adopted, it is possible to observe how the anti-intrusion fencing (1) is formed by: a plurality of interlinked wire meshes (2), which incorporate, at least, a tubular element (3), in horizontal position, with a conductor wire (4) inside, the tubular element (3) being concealed amongst the actual wires, a plurality of posts (5) with a "U" shaped profile with divergent wings ending in respective flanges (6) towards the outside and a plurality of cover bodies (7) closing over the flanges (6) of the profiles forming the plurality of posts (5) on which the plurality of wire meshes (2) converge, in order to be fastened.
The profiles which define the plurality of posts (4) are obtained from a laminar sheet.
In this way, the plurality of electrically welded wire meshes (2) with the incorporation of, at least, one tubular element (3) with a conductor wire (4) inside it, concealed in the wire framework, is not contained within a perimeter frame.
Furthermore, since the conductor wire (4) is inside the corresponding tubular element (3), like a wire, it cannot be detected, making it impossible to know where it is just by looking or even know that the fencing has a sensor element, i.e. the connected conductor wire (4), in such a way that in the event of an intruder cuts the wire mesh (2) with the sensor element to access the restricted zone, it will be detected and the corresponding warning will be sent.
The wire meshes (2) are also manufactured with the tubular element (3) already incorporated with the conductor wire (4) and when erecting the fencing (1) the conductor wires (4) are either connected or not, as the client so wishes.
Therefore, it contributes the significant advantage of the conductor wire housed in the tubular element (3) like a wire not being detectable. When intruders attempt to enter by cutting the wire mesh (2) it is not possible to detect the location of the conductor wire or even detect that it exists, in such a way that, upon intrusion, the conductor wire arranged in a strategic place is cut, which generates an alarm, which in turn makes it possible to know at which point the cut was made.
When mounting the fencing (1), according to the first practical embodiment, the sides of the wire meshes (2) converge on respective posts, being located on the flanges (5) and being fastened by means of the corresponding cover body screwed through the inside of the area to be protected and not being accessible from the outside.
Moreover, in a second practical embodiment of the invention, in the plurality of wire meshes (2) with a series of "V" shaped protrusions (8) that provide rigidity at different height, these protrusions (8) correspond to respective general "V" shaped cuts (9) made along the length of both wings and flanges (6) of the profile forming the posts (5).
Therefore, according to this second practical embodiment, when erecting the fencing (1) the sides of the wire meshes (2) converge on respective posts (5), where respective "V" shaped protrusions (8) of the wire meshes (2), which provide rigidity, coincide with the series of cuts (9), in general "V" shaped cuts, made along the length of both wings and flanges (6) wings and flanges (6).
In this way, the sides of the interlinked wire meshes (2) are located on the flanges (6) on which the divergent wings of the general "U" shaped profiles end, which form the plurality of posts (5), and are fastened by corresponding cover body (7) means fixed to said flanges (6).
This gives rise to an anti-intrusion fencing (1), according to two alternative practical embodiments, which is erected quickly, simply and at low economic cost and is also highly reliable. In addition:

the interlinked wire meshes (2) that form it have a pre-sensor which may or may not be connected in the mounting thereof and
the sensor element is concealed in the wire framework, it being impossible to know where it is located or even that it exists just by looking.

Finally, it can be pointed out that, naturally, the alarm system is based in a control centre, supported on a PC, which managers a number of analyzers or control boxes mounted along the length of the fencing, thereby making it possible to know about any cut which may have occurred and the place it was made and act immediately. The energy required by the intrusion alarm system may be obtained by means of photovoltaic cells.
