Estado de la tecnicaState of the art

En el campo de la seguridad son conocidas las vallas o verjas para impedir el paso de personas. Algunos ejemplos, son aquellas destinadas a impedir el paso de personas al interior de un recinto, o bien a traves de una frontera.In the field of security fences or gates are known to prevent the passage of people. Some examples are those designed to prevent the passage of people inside an enclosure, or through a border.

A lo largo de la historia se han usado distintas tecnologlas para impedir el paso de personas, por ejemplo muros de piedra, ladrillo u hormigon. Este tipo de infraestructuras son de construction lenta y dificultan la vision desde la cara interna que debe hacerse a traves de orificios o bien desde la parte superior del propio muro.Throughout history different technologies have been used to prevent the passage of people, for example, stone walls, brick or concrete. This type of infrastructure is of slow construction and makes it difficult to see from the inside face that must be done through holes or from the top of the wall itself.

El uso de rejados, por ejemplo, soportados mediante postes y con secciones de malla facilitan la vision a traves de la propia valla. Esto permite a los encargados de seguridad identificar potenciales intrusiones u otras situaciones de peligro antes que lleguen a producirse. Sin embargo, resulta diflcil evitar que los potenciales intrusos escalen la valla. The use of gratings, for example, supported by poles and with mesh sections facilitates the vision through the fence itself. This allows security managers to identify potential intrusions or other dangerous situations before they occur. However, it is difficult to prevent potential intruders from escaping the fence.

Asl, en algunos casos se dota la valla de tramos de elementos disuasorios tales como alambres de espino o elementos cortantes. Sin embargo, este tipo de elementos puede llegar a provocar lesiones a quien intenta escalar la valla. Existe un problema adicional debido a que este tipo de vallas deben tener una altura suficiente como para disuadir la escalada: si por ejemplo un potencial intruso recibe un pinchazo o un corte inesperado, incluso si la gravedad de la lesion fuera limitada, la sorpresa puede provocar que pierda el agarre, resultando en una calda que puede ocasionar graves consecuencias.Thus, in some cases the fence is provided with sections of deterrent elements such as barbed wire or cutting elements. However, this type of elements can cause injuries to those who try to climb the fence. There is an additional problem because this type of fences must be high enough to discourage climbing: if, for example, a potential intruder receives a puncture or an unexpected cut, even if the severity of the injury is limited, surprise can cause that loses the grip, resulting in a loss that can cause serious consequences.

Por estos motivos, se hace necesaria una valla defensiva que permita la vision a traves de la misma, que impida y disuada la escalada para potenciales intrusos, y que a la vez minimice el riesgo de lesiones para los potenciales intrusos.For these reasons, it is necessary a defensive fence that allows the vision through it, that prevents and dissuades the escalation for potential intruders, and at the same time minimizes the risk of injury to potential intruders.

Description de la inventionDescription of the invention

La invencion tiene como finalidad proporcionar una valla de seguridad anti-escalada del tipo indicado al principio, que permita resolver los problemas expuestos anteriormente.The purpose of the invention is to provide an anti-escalation security fence of the type indicated at the beginning, which allows to solve the aforementioned problems.

Esta finalidad se consigue mediante una valla del tipo indicado al principio, caracterizado por que dicho segundo tramo se extiende en pendiente negativa respecto dicha cara externa, siendo la cara externa de dicho segundo tramo una superficie lisa.This purpose is achieved by a fence of the type indicated at the beginning, characterized in that said second section extends in negative slope with respect to said external face, the external face of said second section being a smooth surface.

En la tecnica se dice que una pared se extiende en pendiente negativa respecto a una de sus caras si esta inclinada desde la vertical hacia dicha cara. Dicha pendiente negativa dificulta enormemente la escalada y constituye ademas un elemento disuasorio psicologico tanto antes como durante un intento de escalada. Estos efectos se complementan por el hecho que el tramo presenta una superficie lisa en la que no es posible agarrarse. Asl, en el momento que un intruso esta escalando y llega al segundo tramo, no solo se encuentra con una pendiente negativa sino que ademas le resulta imposible encontrar puntos de apoyo para continuar el avance. Este efecto combinado supone una barrera flsica y psicologica para el potencial intruso que ya ha tenido grandes dificultades incluso para pasar el primer tramo, y que en ese momento se enfrenta a un obstaculo que se aprecia como insalvable. De esta forma, el potencial intruso se ve fuertemente incitado a abandonar el ascenso. De esta forma, es posible impedir el paso de intrusos sin necesidad de poner en riesgo la integridad fisica de los mismos.In the technique it is said that a wall extends in negative slope with respect to one of its faces if it is inclined from the vertical toward said face. This negative slope makes climbing very difficult and also constitutes a psychological deterrent both before and during an attempt at climbing. These effects are complemented by the fact that the section presents a smooth surface on which it is not possible to hold on. Thus, at the moment when an intruder is climbing and reaches the second section, not only does he encounter a negative slope, but it is also impossible to find support points to continue the advance. This combined effect supposes a physical and psychological barrier for the potential intruder who has already had great difficulties even to pass the first section, and who at that moment faces an obstacle that is seen as insurmountable. In this way, the potential intruder is strongly encouraged to abandon the ascent. Of This way, it is possible to prevent the intrusion of intruders without having to put at risk the physical integrity of the same.

El extremo superior de la valla queda separado de la vertical del extremo inferior, por lo que no es posible utilizar la propia valla como soporte para apoyar por ejemplo una escalera o bien una columna de personas, unas a hombros de otras, para superar el obstaculo. Tambien, para un eventual escalador que llegase al extremo inferior del segundo tramo, dado que en el tramo en pendiente negativa la valla estaria inclinada por encima de su cabeza le resultaria muy dificil arrojar hacia el extremo superior de la valla un elemento de ayuda a la escalada, por ejemplo un gancho atado a una cuerda, pensado para engancharse en alguna parte del extremo superior de la valla. Efectivamente, dada la configuration, este elemento chocaria contra la parte en pendiente negativa que ademas es una superficie lisa.The upper end of the fence is separated from the vertical of the lower end, so it is not possible to use the fence itself as a support to support for example a ladder or a column of people, one on the shoulders of others, to overcome the obstacle . Also, for an eventual climber who reached the lower end of the second section, since in the negative slope section the fence would be tilted above his head it would be very difficult to throw towards the upper end of the fence an element of help to the climbing, for example a hook attached to a rope, intended to be hooked somewhere in the upper end of the fence. Effectively, given the configuration, this element will collide against the negative sloping part that is also a smooth surface.

Sobre la base de la invention definida en la revindication principal se han previsto unas formas de realization preferentes cuyas caracteristicas se encuentran recogidas en las reivindicaciones dependientes.On the basis of the invention defined in the main claim, preferred embodiments have been provided whose characteristics are set forth in the dependent claims.

Preferentemente, cada section de valla ademas comprende un tercer tramo vertical, previsto entre dicho primer tramo y dicho segundo tramo, colindante con dicho segundo tramo, siendo la cara externa de dicho tercer tramo una superficie lisa. Lo que constituye una barrera adicional al ascenso. Ademas permite que el intruso se de cuenta de la falta de asideros antes incluso de enfrentarse al tramo con pendiente negativa. Asi, el intruso se da cuenta primero de la imposibilidad de asirse, y ve que despues debera enfrentarse ademas a un tramo con pendiente negativa en el que quedaria colgando. Esto produce un efecto disuasorio incrementado que incita de forma mas efectiva al intruso a abandonar el intento de escalada.Preferably, each section of fence also comprises a third vertical section, provided between said first section and said second section, abutting said second section, the external face of said third section being a smooth surface. What constitutes an additional barrier to ascent. It also allows the intruder to realize the lack of handholds before even facing the section with negative slope. Thus, the intruder first realizes the impossibility of grasping, and sees that afterwards he must also face a section with a negative slope in which he would be hanging. This produces an increased deterrent effect that more effectively incites the intruder to abandon the climbing attempt.

Preferentemente, cada seccion de valla ademas comprende un cuarto tramo vertical de malla, previsto en la parte superior de dicha seccion de valla por encima de dicho segundo tramo. Lo que tiene dos ventajas principales: en primer lugar, resulta posible ver desde la cara interna el tramo superior de la valla a traves de la misma. En segundo lugar, se incrementa la distancia entre el segundo tramo y el extremo superior de la valla, lo que incrementa la dificultad de que el intruso pueda usar cuerdas, ganchos o elementos similares para lanzarlos por encima de la valla y obtener asl un posible punto de apoyo para la escalada. Esta es una forma de realization preferente respecto a aquellas en las que el segundo tramo llega hasta el extremo superior de la valla dado que el peso total y la resistencia al viento son menores, y ademas requiere un tamano menor para el segundo tramo para obtener el mismo nivel de seguridad.Preferably, each fence section further comprises a fourth vertical section of mesh, provided in the upper part of said fence section above said second section. What has two main advantages: first, it is possible to see from the inside face the upper section of the fence through it. Secondly, the distance between the second section and the upper end of the fence increases, which increases the difficulty for the intruder to use ropes, hooks or elements similar to launch them over the fence and thus obtain a possible point of support for the climb. This is a preferred embodiment with respect to those in which the second section reaches the upper end of the fence since the total weight and wind resistance are lower, and also requires a smaller size for the second section to obtain the Same level of security.

Preferentemente, cada section de valla ademas comprende un quinto tramo vertical, previsto entre dicho segundo tramo y dicho cuarto tramo, colindante con dicho segundo tramo, siendo la cara externa de dicho quinto tramo una superficie lisa. Incrementando asl la altura total de la zona con superficie lisa exterior.Preferably, each section of fence also comprises a fifth vertical section, provided between said second section and said fourth section, adjacent to said second section, the external face of said fifth section being a smooth surface. Increasing the total height of the area with smooth outer surface.

Preferentemente, dichos tramos que presentan una superficie lisa en su cara externa estan fabricados con chapa metalica en su cara externa. Esto otorga una gran resistencia a la superficie y la hace diflcil de perforar, especialmente si esta fabricada en chapa de acero.Preferably, said sections having a smooth surface on their external face are manufactured with metal sheet on their external face. This gives a great resistance to the surface and makes it difficult to drill, especially if it is made of steel sheet.

Preferentemente, dichos tramos que presentan una superficie lisa en su cara externa comprenden ademas una malla en su cara interna. Lo que permite reducir el grosor de la parte con superficie lisa manteniendo una gran resistencia estructural, permitiendo asl una reduction del peso total.Preferably, said sections having a smooth surface on their external face also comprise a mesh on their internal face. This allows to reduce the thickness of the part with a smooth surface maintaining a great structural resistance, thus allowing a reduction of the total weight.

Preferentemente, dichos postes presentan una superficie plana en su cara externa, lo que facilita la sujecion de las secciones de valla a la cara externa del poste. Preferentemente presentando un perfil en forma de H, tambien conocidos como perfil en doble T o perfil IPE. Este tipo de perfil, usado por ejemplo en vigas y otros elementos estructurales de construction, presenta una gran resistencia en relation al peso.Preferably, said posts have a flat surface on their external face, which facilitates the fastening of the fence sections to the external face of the pole. Preferably having a profile in the form of H, also known as double-T profile or IPE profile. This type of profile, used for example in beams and other structural elements of construction, has a great resistance in relation to weight.

Preferentemente, cada seccion de valla esta fijada a dichos postes mediante unas pletinas de union dispuestas para aprisionar la seccion de valla contra la cara externa de los postes. La seccion de valla queda asl aprisionada entre la pletina y el poste en una configuration en sandwitch. Adicionalmente, la pletina presenta una superficie lisa que esconde los elementos de sujecion y dificulta todavla mas el agarre.Preferably, each fence section is fixed to said posts by means of union plates arranged to clamp the fence section against the external face of the posts. The fence section is thus imprisoned between the plate and the pole in a configuration in sandwitch. Additionally, the plate has a smooth surface that hides the fastening elements and further hinders the grip.

Preferentemente, dichas pletinas estan sujetas a dichos postes mediante unos tornillos que presentan en su cara externa una cabeza configurada para evitar la sujecion de una herramienta de desmontaje o una mano. Este tipo de tornillos se conocen como tornillos de cabeza indesmontable e imposibilitan que puedan ser desmontados desde la cara externa. Preferentemente, la cabeza presenta una forma de cupula o sector esferico, lo que ademas impide usarlos como puntos de apoyo para la escalada.Preferably, said plates are fastened to said posts by means of screws that present on their external face a head configured to prevent the clamping of a disassembly tool or one hand. This type of screws are known as non-removable head screws and prevent them from being dismantled from the external face. Preferably, the head has a dome shape or spherical sector, which also prevents using them as support points for climbing.

Preferentemente, dicha malla es del tipo conocido como mallazo, es decir, una malla ortogonal de alambres verticales y horizontales, en la que dichos alambres verticales y horizontales se encuentran soldados entre si en los puntos de intersection, preferentemente mediante electrosoldadura. Este tipo de malla resulta muy robusta en relation a su peso y ademas es posible escoger el tamano del entrelazado del mallazo para dificultar la escalada por el mismo. En particular, una forma preferente utiliza una reticula de 12,7 x 76,2mm.Preferably, said mesh is of the type known as mesh, that is, an orthogonal mesh of vertical and horizontal wires, in which said vertical and horizontal wires are welded together at the points of intersection, preferably by electrowelding. This type of mesh is very robust in relation to its weight and also it is possible to choose the size of the mesh interlace to hinder climbing by it. In particular, a preferred shape uses a 12.7 x 76.2mm cross-link.

Preferentemente, dichos alambres presentan un diametro de entre 3 y 5mm, preferentemente de 4mm. El diametro debe ser suficientemente grande como para impedir el corte de la malla, y a la vez lo suficientemente pequeno para que no facilite un eventual punto de apoyo a la escalada, ni aumente demasiado el peso del conjunto.Preferably, said wires have a diameter between 3 and 5mm, preferably 4mm. The diameter must be large enough to prevent the mesh from being cut, and at the same time small enough so that it does not provide a possible point of support for the climb, nor does it increase the weight of the assembly too much.

Preferentemente, dicha valla presenta una altura de 8 metros o mas, preferentemente de 9 metros. Lo que supone un obstaculo que se aprecia ya demasiado alto y que, por tanto disuade la intrusion.Preferably, said fence has a height of 8 meters or more, preferably of 9 meters. What is an obstacle that is already too high and that therefore discourages the intrusion.

Preferentemente, en cada section de valla, dicho primer tramo presenta una altura de 5 metros o mas, preferentemente de 6 metros. Esta altura equivale a mas de la altura de dos personas adultas, por lo que un potencial intruso no puede superar la altura del primer tramo ni siquiera subiendose a hombros de un companero.Preferably, in each fence section, said first section has a height of 5 meters or more, preferably of 6 meters. This height is equivalent to more than the height of two adults, so a potential intruder can not exceed the height of the first section or even climbing on the shoulders of a partner.

Preferentemente, en cada seccion de valla, la distancia entre el extremo inferior de dicho segundo tramo y el extremo superior de la seccion de valla es de por lo menos 2,5 metros. Lo que imposibilita a un escalador que haya llegado al extremo inferior del segundo tramo extenderse hasta alcanzar el extremo superior de la valla, incluso si intentase lanzar algun dispositivo de ayuda tipo una cuerda o gancho.Preferably, in each fence section, the distance between the lower end of said second section and the upper end of the fence section is at least 2.5 meters. What makes it impossible for a climber who has reached the lower end of the second section to reach the top end of the fence, even if he tried to throw some kind of help device like a rope or hook.

Preferentemente, en cada seccion de valla, dicho segundo tramo presenta una altura de por lo menos 1 metro. Lo que impide que un escalador pueda superar el paso por el segundo tramo sin necesitar un punto de sujecion que deberla estar en la zona que presenta superficie lisa.Preferably, in each fence section, said second section has a height of at least 1 meter. What prevents a climber from passing through the second section without needing a point of subjection that should be in the area that presents smooth surface.

Preferentemente, en cada seccion de valla, dicho segundo tramo se encuentra inclinado entre 10° y 80° respecto la vertical, preferentemente, entre 15° y 45°, mas preferentemente 30°. Asl, dicho segundo tramo contribuye positivamente a la altura total de la valla, y esta dispuesto de forma que los postes puedan aguantar las cargas de la parte superior, pero que a la vez dificulten suficientemente la escalada. Un valor de 30° se ha mostrado que resulta optimo en este caso, especialmente combinado con una altura de aproximadamente 1,1m para el segundo tramo, lo que supone que el tramo tiene una longitud de aproximadamente 1,27m.Preferably, in each fence section, said second section is inclined between 10 ° and 80 ° with respect to the vertical, preferably between 15 ° and 45 °, more preferably 30 °. Thus, said second section contributes positively to the total height of the fence, and is arranged so that the posts can withstand the loads of the upper part, but which at the same time make the climbing difficult enough. A value of 30 ° has been shown to be optimal in this case, especially combined with a height of approximately 1.1m for the second section, which means that the section has a length of approximately 1.27m.

Preferentemente, cada seccion de valla presenta una anchura de entre 1,5 y 2,5 metros. En particular, se ha comprobado que 2 metros supone un equilibrio optimo entre visibilidad, peso total y resistencia.Preferably, each fence section has a width of between 1.5 and 2.5 meters. In particular, it has been proven that 2 meters represents an optimal balance between visibility, total weight and resistance.

La invention tambien abarca otras caracterlsticas de detalle ilustradas en la description detallada de una forma de realization de la invencion y en las figuras que la acompanan.The invention also encompasses other detailed features illustrated in the detailed description of one embodiment of the invention and the accompanying figures.

La valla 1 comprende unos postes 3 de soporte; y por lo menos una seccion de valla 2. Cada seccion de valla 2 esta delimitada por dos de dichos postes 3 y fijada a los mismos. Para el ejemplo, la Fig. 1 muestra una valla 1 con unica seccion de valla 2. Los postes 3 pueden anclarse al suelo de distintas formas conocidas en la tecnica. En las figuras se muestra un ejemplo en el que cada poste 3 esta provisto de un armazon 31 en su extremo inferior dispuesto para quedar fijado en un orificio en el suelo que se rellena con hormigon. En los ejemplos, los postes 3 presentan un perfil en forma de H, en particular un perfil del tipo IPE-300, con una superficie sustancialmente plana en su cara externa 5.In a first embodiment shown in FIGS. 1 and 2, the safety barrier 1 has an internal face 4 and an external face 5. The fence 1 comprises support posts 3; and at least one section of fence 2. Each section of fence 2 is delimited by two of said posts 3 and fixed thereto. For the example, Fig. 1 shows a fence 1 with a single fence section 2. The posts 3 can be anchored to the ground in various ways known in the art. In the figures an example is shown in which each post 3 is provided with a frame 31 at its lower end arranged to be fixed in a hole in the ground that is filled with concrete. In the examples, posts 3 they have an H-shaped profile, in particular a profile of the IPE-300 type, with a substantially flat surface on its external face 5.

Cada seccion de valla 2 comprende un primer tramo 11 vertical de malla 10, previsto en la parte inferior de dicha seccion de valla 2, y un segundo tramo 12, previsto por encima de dicho primer tramo 11. Tal y como se aprecia en las Fig. 1 y 2, el segundo tramo 12 se extiende en pendiente negativa respecto dicha cara externa 5. Ademas, la cara externa 5 del segundo tramo 12 es una superficie lisa 20 que en el caso del ejemplo esta fabricada en chapa de acero. En los ejemplos de las figuras los tramos que, como en el caso del segundo tramo 12, presentan una superficie lisa 20 en su cara externa 5, comprenden ademas una malla en su cara interna 4. Esto se aprecia por ejemplo en el detalle de la Fig. 9.Each fence section 2 comprises a first vertical section 11 of mesh 10, provided in the lower part of said section of fence 2, and a second section 12, provided above said first section 11. As can be seen in Figs. 1 and 2, the second section 12 extends in negative slope with respect to said external face 5. Furthermore, the external face 5 of the second section 12 is a smooth surface 20 which in the case of the example is made of steel sheet. In the examples of the figures, the sections that, as in the case of the second section 12, have a smooth surface 20 on its external face 5, also comprise a mesh on its internal face 4. This is seen, for example, in the detail of the Fig. 9

El tipo de malla 10 usada en esta forma de realization es del tipo conocido como mallazo, es decir, una malla ortogonal de alambres verticales y horizontales, en la que dichos alambres verticales y horizontales se encuentran soldados entre si en los puntos de intersection mediante electrosoldadura. Ejemplo de detalle de este tipo de malla se aprecian en las Fig. 6 y 7. Para el ejemplo, los alambres de la malla 10 presentan un diametro de 4mm y la malla presenta un paso reticular de 12,7 x 76,2mm. Ademas, la malla 10 esta recubierta por una capa de pollmero con un espesor mlnimo de 100 micras para su protection contra corrosion.The type of mesh 10 used in this form of realization is of the type known as mesh, that is, an orthogonal mesh of vertical and horizontal wires, in which said vertical and horizontal wires are welded together at the points of intersection by electrowelding . Example of detail of this type of mesh can be seen in Fig. 6 and 7. For the example, the wires of the mesh 10 have a diameter of 4mm and the mesh has a reticular pitch of 12.7 x 76.2mm. In addition, the mesh 10 is coated with a polymer layer with a minimum thickness of 100 microns for its protection against corrosion.

A continuation se muestran otras formas de realizacion de la valla de seguridad segun la invention que comparten gran parte de las caracterlsticas descritas en los parrafos anteriores. Por consiguiente, en adelante solo se describiran los elementos diferenciadores, mientras que para los elementos comunes se hace referencia a la description de la primera forma de realizacion.In the following, other forms of realization of the security fence according to the invention are shown, which share a large part of the characteristics described in the previous paragraphs. Accordingly, only the differentiating elements will be described hereinafter, while for the common elements reference is made to the description of the first embodiment.

En algunas formas de realizacion, cada seccion de valla 2 ademas comprende un tercer tramo 13 vertical, previsto entre el primer y segundo tramos 11 y 12, colindante con el segundo tramo 12. La cara externa 5 del tercer tramo 13 es una superficie lisa 20, por ejemplo de chapa de acero. La Fig. 3 muestra un ejemplo que incorpora dicho tercer tramo 13 intermedio entre el primer y segundo tramos 11 y 12. El ejemplo de la figura incorpora ademas otras caracterlsticas que se describen a continuacion. In some embodiments, each section of the fence 2 also comprises a third vertical section 13, provided between the first and second sections 11 and 12, adjacent to the second section 12. The external face 5 of the third section 13 is a smooth surface 20 , for example made of steel sheet. Fig. 3 shows an example incorporating said third intermediate section 13 between the first and second sections 11 and 12. The example of the figure also incorporates other characteristics described below.

Para algunas formas de realization, cada section de valla 2 ademas comprende un cuarto tramo 14 vertical de malla 10, previsto en la parte superior de dicha section de valla 2 por encima del segundo tramo 12. Entre estas formas de realization, algunas de ellas, como por ejemplo la mostrada en la Fig. 3 ademas comprenden un quinto tramo 15 vertical, que esta previsto entre el segundo y el cuarto tramo 12 y 14, de forma que colinda con el segundo tramo 12. La cara externa 5 del quinto tramo 15 es tambien una superficie lisa 20, por ejemplo de chapa de acero.For some forms of realization, each section of fence 2 also comprises a fourth vertical section 14 of mesh 10, provided in the upper part of said section of fence 2 above the second section 12. Among these forms of realization, some of them, as for example that shown in Fig. 3 also comprise a fifth vertical section 15, which is provided between the second and fourth sections 12 and 14, so that it abuts the second section 12. The external face 5 of the fifth section 15 it is also a smooth surface 20, for example of sheet steel.

La forma de fijacion de cada section de valla 2 con los postes 3 puede tener distintas formas. En algunas de ellas, por ejemplo, las mostradas en las Fig. 6 y 7, se fijan directamente al poste 3 mediante unos medios de fijacion que en este caso comprenden unos tornillos 7 que, una vez colocados en position de uso, presentan en su cara externa 5 una cabeza 8 del tipo conocido como indesmontable, y que esta configurada para evitar la sujecion de una herramienta de desmontaje o una mano. En el caso de las figuras la cabeza 8 presenta una forma de cupula o sector esferico. En particular, para los ejemplos se usan tornillos del tipo DIN 603-A2 M.8.The fixing method of each section of the fence 2 with the posts 3 can have different shapes. In some of them, for example, those shown in Fig. 6 and 7, are fixed directly to the post 3 by fixing means that in this case comprise screws 7 that, once placed in position of use, present in their external face 5 a head 8 of the type known as indesmontable, and which is configured to prevent the clamping of a disassembly tool or a hand. In the case of the figures, the head 8 has a dome shape or spherical sector. In particular, screws of the type DIN 603-A2 M.8 are used for the examples.

En otros ejemplos, como los de la Fig. 7, cada section de valla 2 esta fijada a dichos postes 3 mediante unas pletinas 6 de union dispuestas para aprisionar la section de valla 2 contra la cara externa 5 de los postes 3. En la figura se muestra un detalle en section de uno de los tramos con superficie exterior lisa 20, es decir, cualquiera de entre el segundo tramo 12, tercer tramo 13 o quinto tramo 15. Las figuras 6 y 7 se muestran totalmente en vertical porque en estos casos no se han orientado segun la position de uso de la valla sino de forma longitudinal al propio tramo que representan.In other examples, such as those of Fig. 7, each section of fence 2 is fixed to said posts 3 by means of joining strips 6 arranged to clamp the fence section 2 against the external face 5 of the posts 3. In the figure a sectional detail of one of the sections with smooth outer surface 20 is shown, that is to say, any of between the second section 12, third section 13 or fifth section 15. Figures 6 and 7 are shown completely in vertical because in these cases they have not been oriented according to the use position of the fence but longitudinally to the section they represent.

La valla 1 mostrada en las Fig. 3, 4 y 5 presenta una altura de alrededor de 9 metros, en particular, de 9,15 metros. Con un primer tramo 11 de unos 6 metros, en particular de 6,04 metros, y un segundo tramo 12 inclinado unos 30° respecto la vertical y una altura de 1,1 metros, lo que corresponde a una longitud de 1,27m dada la inclination. En el caso del ejemplo, la distancia vertical entre el extremo inferior del segundo tramo 12 y el extremo superior de la section de valla es de 3,1 m. Para el ejemplo, esta distancia corresponde a la suma de las alturas del segundo tramo 12, cuarto tramo 14 y quinto tramo 15. Otras medidas e inclinaciones son posibles en funcion de los requerimientos del terreno o de la zona que se quiera defender, asl como de los materiales utilizados para la fabrication de la valla 1.The fence 1 shown in Fig. 3, 4 and 5 has a height of about 9 meters, in particular, of 9.15 meters. With a first section 11 of about 6 meters, in particular of 6.04 meters, and a second section 12 inclined about 30 ° with respect to the vertical and a height of 1.1 meters, which corresponds to a given length of 1.27m the inclination. In the case of the example, the vertical distance between the lower end of the second section 12 and the upper end of the section of the fence is 3.1 m. For the example, this distance corresponds to the sum of the heights of the second section 12, fourth section 14 and fifth section 15. Other measurements and inclinations are possible depending on the requirements of the terrain or the area that you want to defend, as well as the materials used for the manufacture of the fence 1.
