Description

ESTRUCTURA DE VALLA GUARDARRAIL  GUARDARRAIL VALLEY STRUCTURE

OBJETO DE LA INVENCION  OBJECT OF THE INVENTION

La presente invención, según se expresa en el enunciado de esta memoria descriptiva, se refiere a una estructura de valla guardarrail que presenta la particularidad de comprender elementos de retención con una configuración tubular cerrada a modo de air-bag distinta de la circular, de manera que la dirección del impacto de un vehículo es perpendicular a la dirección del eje mayor de esa configuración tubular de la estructura guardarrail.  The present invention, as expressed in the statement of this specification, refers to a guardrail fence structure that has the particularity of comprising retention elements with a closed tubular configuration as an airbag other than the circular one, so that the direction of impact of a vehicle is perpendicular to the direction of the major axis of that tubular configuration of the guardrail structure.

La geometría tubular no circular es fundamental para lograr la adecuada amortiguación y deformación tras el impacto, que no ocurriría por ejemplo en un elemento de sección circular, plano o plano ondulado.  Non-circular tubular geometry is essential to achieve adequate damping and deformation after impact, which would not occur, for example, in an element of circular, flat or wavy plane section.

Otro objetivo de la invención es conseguir una amortiguación efectiva en la vinculación de los elementos de retención con respecto a los postes a los que se fijan tales elementos de amortiguación.  Another object of the invention is to achieve an effective damping in the linking of the retention elements with respect to the posts to which such damping elements are fixed.

La estructura de la invención tiene como finalidad dos misiones fundamentales que cumplir y que son las más importantes en un siniestro:  The purpose of the structure of the invention is two fundamental missions to fulfill and which are the most important in an accident:

amortiguar al máximo el impacto que reciba la persona al colisionar directa o indirectamente contra la valla de protección, minimizando sus consecuencias,  maximize the impact that the person receives by directly or indirectly colliding with the protection fence, minimizing its consequences,

impedir en la medida de lo posible, que el vehículo salga de la calzada, atravesando el elemento de contención .  prevent, as far as possible, the vehicle from leaving the road, crossing the containment element.

ANTECEDENTES DE LA INVENCION  BACKGROUND OF THE INVENTION

En la actualidad, son conocidas distintas estructuras de valla guardarrailes que comprenden perfiles longitudinales como elementos de retención de los impactos, fijándose tales perfiles longitudinales a unos postes hincados en el suelo, bien directamente o bien por mediación de unas piezas intermedias que se atornillan a los postes y también a los propios perfiles longitudinales.At present, different guardrail fence structures are known that comprise longitudinal profiles as elements of retention of impacts, such longitudinal profiles being fixed to posts driven into the ground, either directly or by means of intermediate pieces that are screwed to the posts and also to the longitudinal profiles themselves.

Asi pues son conocidos los guardarrailes determinados por unas vallas biondas que existen en los países más avanzados y que corresponden a formatos y desarrollos tecnológicos y de mecanización propios del pasado. Este tipo de vallas protectoras (biondas) llevan más de treinta años y su evolución ha sido prácticamente irrelevante. Thus, the guardrails determined by bionate fences that exist in the most advanced countries and that correspond to technological and mechanization formats and developments of the past are known. These types of protective fences (biondas) have been going on for more than thirty years and their evolution has been practically irrelevant.

En los sistemas existentes ha prevalecido el coste por kilómetro de seguridad, sobre el propio espíritu de la seguridad en sí misma.  In existing systems, the cost per kilometer of security has prevailed, over the spirit of security itself.

Por lo tanto todas las vallas protectoras para guardarrailes son productos de continuaciones evolucionadas de lo ya existente, si bien se acometían con diferentes posibilidades de construcción, tanto en formas como en materiales empleados, de manera que el mal de fondo seguía sin recibir una solución, ya que tales vallas están fabricadas con perfiles metálicos preformados y cortados a canto vivo que pueden actuar de manera directa, provocando cortes, amputaciones y muerte, o de manera indirecta, mediante atrapamientos e inmovilización. La segunda parte del mal de fondo es la entredicha efectividad de retención del vehículo, del conductor y de posibles ocupantes o pasaj eros .  Therefore, all the fences for guardrails are products of continuations evolved from what already exists, although they were undertaken with different construction possibilities, both in forms and in materials used, so that the underlying evil still did not receive a solution, since such fences are manufactured with preformed metal profiles and cut to live edge that can act directly, causing cuts, amputations and death, or indirectly, by entrapment and immobilization. The second part of the underlying evil is the critical effectiveness of retention of the vehicle, the driver and possible occupants or passengers.

DESCRIPCION DE LA INVENCION  DESCRIPTION OF THE INVENTION

Con el fin de alcanzar los objetivos y evitar los inconvenientes mencionados en los apartados anteriores, la invención propone una estructura de valla guardarrail que se determina a partir de unos perfiles longitudinales que se fijan a unos postes anteriores hincados en el suelo, fijación que se realiza mediante unos elementos intermedios .  In order to achieve the objectives and avoid the inconveniences mentioned in the previous sections, the invention proposes a guardrail fence structure that is determined from longitudinal profiles that are fixed to previous posts driven into the ground, fixing that is carried out through intermediate elements.

Se caracteriza porque los perfiles longitudinales comprenden cuerpos tubulares longitudinales con una sección cerrada diferente de la circular, con al menos una zona de deformación o plegado en uno de los extremos del eje mayor de tal sección tubular, estando dicho eje mayor dispuesto perpendicularmente a la dirección del impacto del vehículo.It is characterized in that the longitudinal profiles comprise longitudinal tubular bodies with a closed section different from the circular one, with at least one deformation or folding zone at one of the ends of the major axis of said tubular section, said major axis being arranged perpendicular to the direction of impact of the vehicle.

Esa zona de deformación de los cuerpos longitudinales comprende un pliegue doblado hacia el interior que tiene una configuración angular o arqueada. That zone of deformation of the longitudinal bodies comprises a fold folded inwards that has an angular or arched configuration.

Los perfiles longitudinales presentan una sección tubular seleccionada, por ejemplo, entre una sección ovoide, elíptica u oval.  The longitudinal profiles have a tubular section selected, for example, between an ovoid, elliptical or oval section.

Otra característica fundamental de la invención es la forma de vincular este elemento de retención a los postes anteriores dispuestos verticalmente, resuelta mediante unos elementos intermedios materializados por amortiguadores mecánicos, formados por unas piezas de lámina plegada a modo de fuelle, que constituye otro elemento para disipar la energía del impacto.  Another fundamental characteristic of the invention is the way of linking this retaining element to the vertically arranged anterior posts, resolved by means of intermediate elements materialized by mechanical dampers, formed by pieces of folded sheet as a bellows, which constitutes another element to dissipate The energy of impact.

Así pues, estos amortiguadores mecánicos comprenden una parte anterior envolvente a modo de abrazadera para fijarse a los postes mediante unos elementos de fijación, tales como tornillos y tuercas, y una parte posterior que comprende las piezas de lámina plegada constitutivas de los amortiguadores propiamente dichos.  Thus, these mechanical shock absorbers comprise a wrap-around front part as a clamp to be fixed to the posts by means of fixing elements, such as screws and nuts, and a rear part comprising the folded sheet pieces constituting the shock absorbers themselves.

Otra característica de la invención es que los distintos cuerpos tubulares longitudinales adyacentes se unen entre sí por mediación de unas piezas tubulares intermedias acopladas en los extremos de los cuerpos tubulares longitudinales mediante una conexión macho- hembra, asegurándose la unión mediante unos elementos de anclaj e .  Another feature of the invention is that the different adjacent longitudinal tubular bodies are joined together by means of intermediate tubular pieces coupled at the ends of the longitudinal tubular bodies by means of a male-female connection, the union being secured by means of anchoring elements.

La incorporación de tales piezas tubulares intermedias evitan, ante un impacto, que los bordes de los cuerpos tubulares longitudinales se claven en el vehículo que impacta, como viene ocurriendo en algunos guardarrailes convencionales .  The incorporation of such intermediate tubular parts prevents, in the event of an impact, that the edges of the longitudinal tubular bodies are stuck in the impacting vehicle, as is the case in some conventional guardrails.

Estas piezas tubulares intermedias se fijan a los postes también mediante los característicos amortiguadores mecánicos.  These intermediate tubular parts are fixed to the posts also by the characteristic mechanical dampers.

A su vez, uno de los extremos de las piezas tubulares intermedias y uno de los extremos de los cuerpos tubulares longitudinales cuentan con unos orificios pasantes enfrentados con unas aberturas establecidas en los extremos opuestos de los cuerpos tubulares longitudinales y piezas tubulares intermedias. In turn, one of the ends of the tubular pieces intermediate and one of the ends of the longitudinal tubular bodies have through holes facing each other with openings established at opposite ends of the longitudinal tubular bodies and intermediate tubular parts.

Alrededor de las aberturas citadas existen unos rehundidos perimetrales para albergar unas aletas perimetrales que forman parte de unas tuercas móviles alojadas en tales aberturas, de manera que una vez dispuestas las tuercas móviles con sus aletas perimetrales asentadas y ubicadas en los rehundidos perimetrales referidos, se procede a encajar atornillando los extremos adyacentes de piezas tubulares intermedias y cuerpos tubulares longitudinales por machihembrado hasta que las tuercas móviles queden enfrentadas con los orificios pasantes correspondientes con esas piezas y cuerpos tubulares para proceder a acoplar unos tornillos exteriores que roscan en tales tuercas móviles y aseguran la fijación entre cuerpos tubulares longitudinales y piezas tubulares intermedias. El desplazamiento de las tuercas móviles facilita el acoplamiento de los tornillos exteriores cuando los orificios pasantes de los extremos de las piezas tubulares intermedias y cuerpos tubulares longitudinales no queden enfrentados exactamente con los pasos roscados de las tuercas móviles.  Around the aforementioned openings there are perimeter recesses to house perimeter fins that are part of some mobile nuts housed in such openings, so that once the mobile nuts are arranged with their perimetral fins seated and located in the recessed perimeter recesses, we proceed to fit by screwing the adjacent ends of intermediate tubular parts and longitudinal tubular bodies by tongue and groove until the mobile nuts face the corresponding through holes with those pieces and tubular bodies to proceed to attach external screws that thread into such mobile nuts and secure the fixing between longitudinal tubular bodies and intermediate tubular parts. The movement of the mobile nuts facilitates the coupling of the outer screws when the through holes of the ends of the intermediate tubular pieces and longitudinal tubular bodies are not exactly faced with the threaded passages of the mobile nuts.

Cuando se disponen dos alineaciones, una superior y otra inferior, de cuerpos tubulares longitudinales, el borde inferior de la alineación superior presenta un arqueamiento que se complementa con la curvatura del borde superior de los cuerpos tubulares longitudinales inferiores .  When two alignments, one upper and one lower, of longitudinal tubular bodies are arranged, the lower edge of the upper alignment has an arc that is complemented by the curvature of the upper edge of the lower longitudinal tubular bodies.

En el hueco curvado generado entre las dos alineaciones de los cuerpos tubulares longitudinales se puede ajusfar un perfil continuo de material elástico con una porción exterior reflectante o a base de leds alimentados por una célula fotovoltaica . Los amortiguadores mecánicos que se asocian a las piezas tubulares intermedias cuentan con un par de alas horizontales próximas entre si, entre las que se encaja una aleta intermedia solidaria de las piezas tubulares intermedias, de manera que dicha aleta intermedia y alas horizontales se unen entre si mediante unos tornillos y tuercas . In the curved hollow generated between the two alignments of the longitudinal tubular bodies, a continuous profile of elastic material can be adjusted with a reflective outer portion or based on LEDs fed by a photovoltaic cell. The mechanical dampers that are associated with the intermediate tubular parts have a pair of horizontal wings close to each other, between which an intermediate flap integral with the intermediate tubular pieces is fitted, so that said intermediate fin and horizontal wings are joined together by means of screws and nuts.

Unos amortiguadores mecánicos cuentan con una pared frontal afectada de una ranura para fijarse directamente a los cuerpos tubulares longitudinales con ayuda de otros tornillos y tuercas.  Mechanical dampers have an affected front wall of a groove to be fixed directly to the longitudinal tubular bodies with the help of other screws and nuts.

La invención también prevé un reforzamiento posterior de la estructura de valla guardarrail mediante unos postes posteriores y unas vigas horizontales que se vinculan a tales postes posteriores mediante unas abrazaderas unidas a los postes posteriores. A su vez, tales vigas horizontales contactan con los postes anteriores, de manera que ante un impacto de un vehículo contra la estructura de valla, toda ella actúa conjuntamente incluyendo el reforzamiento posterior, muy efectivo este ante el impacto de los vehículos más pesados.  The invention also provides for a further reinforcement of the guardrail fence structure by means of rear posts and horizontal beams that are linked to such rear posts by means of clamps attached to the rear posts. In turn, such horizontal beams contact the previous posts, so that in the event of an impact of a vehicle against the fence structure, it all acts together including the subsequent reinforcement, which is very effective when faced with the impact of heavier vehicles.

Ese reforzamiento posterior se complementa además con una rejilla de acero de protección enmarcada por un cable de acero perimetral que se fija a los postes posteriores mediante unas piezas anulares.  This rear reinforcement is further complemented by a protective steel grid framed by a perimeter steel cable that is fixed to the rear posts by means of annular pieces.

Por otro lado, se han previsto unas piezas macizas de material blando y elástico para reforzar las uniones, piezas que se ajustan en al menos parte del interior de los cuerpos tubulares longitudinales y piezas tubulares intermedias de unión, contando tales piezas macizas con unos ranurados longitudinales para el alojamiento de las tuercas y cabezas de los tornillos.  On the other hand, solid pieces of soft and elastic material are provided to reinforce the joints, pieces that fit in at least part of the interior of the longitudinal tubular bodies and intermediate tubular joining pieces, counting such solid parts with longitudinal grooves for housing the nuts and bolt heads.

Se han previsto también otras piezas terminales curvadas y rectas con terminaciones abombadas para suavizar los impactos y evitar lesiones más graves en la medida de lo posible. Otra característica de la invención es que algunas piezas tubulares intermedias incorporan un fuelle mecanizado para poder adaptar su unión mejor con los cuerpos tubulares longitudinales, cuando forman curvaturas. Other curved and straight end pieces with bulging ends are also provided to soften impacts and avoid more serious injuries as much as possible. Another feature of the invention is that some intermediate tubular parts incorporate a machined bellows so as to be able to adapt their union better with the longitudinal tubular bodies, when they form curvatures.

También se ha previsto que sobre los cuerpos tubulares longitudinales se fijen unos elementos reflectores unitarios .  It is also provided that unit reflector elements are fixed on the longitudinal tubular bodies.

Así pues, la estructura de la invención ofrece una deformación progresiva en tres áreas y secciones diferentes. La estructura tubular de los cuerpos tubulares longitudinales están diseñados para actuar como un airbag, además de evitar atrapamientos, cortes, amputaciones, etc., ya que ninguno de los elementos que componen la estructura posee elementos de canto vivo cortantes a la vista o en estado receptivo de vehículos o personas. Cabe señalar que cuando se disponen varios cuerpos tubulares longitudinales, entre ellos existirá un espacio aproximado de unos 2 centímetros .  Thus, the structure of the invention offers progressive deformation in three different areas and sections. The tubular structure of the longitudinal tubular bodies are designed to act as an airbag, in addition to preventing entrapment, cuts, amputations, etc., since none of the elements that make up the structure have lively sharp or visible edge singing elements. receptive of vehicles or people. It should be noted that when several longitudinal tubular bodies are arranged, there will be an approximate space of about 2 centimeters between them.

Cuando impacta un vehículo contra la valla de la invención los cuerpos tubulares longitudinales se van plegando hacia el vacío interior o hacia la viga encastrada con amortiguadores posteriores que van frenando el impacto total del vehículo.  When a vehicle hits the fence of the invention, the longitudinal tubular bodies are folded towards the interior vacuum or towards the embedded beam with rear shock absorbers that slow down the total impact of the vehicle.

Cabe señalar que los perfiles tubulares longitudinales pueden ser montados sobre el actual sistema de vigas encastradas existentes en la red nacional de cualquier país y en aquellos trazados de nueva ejecución.  It should be noted that the longitudinal tubular profiles can be mounted on the current system of embedded beams existing in the national network of any country and in those paths of new execution.

Además, cabe señalar que el reforzamiento posterior de la estructura de valla de la invención permite anclar al suelo vigas intermedias a las existentes de mayor sección y altura para evitar huecos y salidas de calzada de autobuses y camiones, todo ello debidamente protegido por los característicos cuerpos tubulares longitudinales y por el sistema integral de seguridad que une el conjunto posterior con un armado estructural.  In addition, it should be noted that the subsequent reinforcement of the fence structure of the invention allows intermediate beams to be anchored to the existing ones of greater section and height to avoid gaps and exits of bus and truck roads, all duly protected by the characteristic bodies longitudinal tubular and by the integral security system that joins the rear assembly with a structural reinforcement.

El reforzamiento posterior reparte la fuerza del impacto ante todos los postes existentes en los que va montado dicho sistema, de ese modo se neutraliza el posible arrancamiento de una viga encastrada cuando se impacta bruscamente entre dos de ellas o directamente sobre una. The subsequent reinforcement distributes the force of the impact on all the existing posts on which said system is mounted, thereby neutralizing the possible starting of a embedded beam when it hits sharply between two of them or directly on one.

El sistema de seguridad posterior es un repartidor de cargas y esfuerzo elevado al máximo nivel. El complemento final de este conjunto es de red de acero de atrapamiento (rejilla de protección) absoluto del vehículo para evitar caídas al vacío, en caso de riesgo a despeñarse.  The rear security system is a high load and effort splitter at the highest level. The final complement of this set is the absolute entrapment steel (protection grid) of the vehicle to avoid falls in a vacuum, in case of risk of falling apart.

En resumen pues la estructura de la invención ha sido estudiada minuciosamente en cada uno de sus elementos, ofreciendo así el conjunto completo y necesario para una instalación integral de máxima seguridad y fiabilidad.  In summary, the structure of the invention has been thoroughly studied in each of its elements, thus offering the complete and necessary set for an integral installation of maximum safety and reliability.

Incluye la invención además unas piezas anulares que abrazan complementariamente a los cuerpos tubulares longitudinales para fijar el guardarrail a un pilar o muro mediante unas pletinas perforadas que forman parte de tales piezas anulares de manera que esta fijación se suele realizar en tramos terminales de los guardarrailes con ayuda de tornillos que se fijarán en tales muros o pilares.  The invention also includes annular pieces that complementaryly embrace the longitudinal tubular bodies to fix the guardrail to a pillar or wall by means of perforated plates that are part of such annular pieces so that this fixation is usually carried out in terminal sections of the guardrails with Screw support to be fixed on such walls or pillars.

Por otro lado, cabe señalar que el primer perfil tubular longitudinal más próximo al suelo tiene la misión exclusivamente de preservar impactos de motocicletas, ciclistas, etc ; y que su diseño y características son específicas y diferenciadoras del resto de cuerpos tubulares longitudinales superiores, ya que tiene un perfil diferente, a la vez que su espesor en chapa será aproximadamente entre 0,6/0,8 mm. Un segundo perfil tubular longitudinal para coches partirá de un espesor de chapa de aproximadamente 2/2,5 mm y un tercer perfil tubular longitudinal tendrá un espesor aproximado de 3/3,5 mm.  On the other hand, it should be noted that the first longitudinal tubular profile closest to the ground has the mission exclusively to preserve impacts of motorcycles, cyclists, etc; and that its design and characteristics are specific and differentiating from the rest of the upper longitudinal tubular bodies, since it has a different profile, at the same time that its sheet thickness will be approximately between 0.6 / 0.8 mm. A second longitudinal tubular profile for cars will start from a sheet thickness of approximately 2 / 2.5 mm and a third longitudinal tubular profile will have an approximate thickness of 3 / 3.5 mm.

El guardarrail de la invención permite, mediante la acumulación de cuerpos tubulares longitudinales en vertical dispuestos en alineaciones horizontales uno encima de otro, alcanzar alturas que cubran los posibles impactos de autobuses y camiones, consiguiendo con ello una gran efectividad en la retención de los impactos de esos vehículos de mayores dimensiones citados como autobuses y camiones y otros vehículos similares. The guardrail of the invention allows, by means of the accumulation of longitudinal vertical tubular bodies arranged in horizontal alignments one above the other, to reach heights that cover the possible impacts of buses and trucks, thereby achieving a large effectiveness in retaining the impacts of these larger vehicles mentioned as buses and trucks and other similar vehicles.

Por último cabe señalar que los distintos elementos que componen el conjunto de la estructura de la invención, no tiene ninguno de ellos partes al aire cortantes o traumáticas que de por sí y ante una colisión puedan herir, mutilar o causar muerte por ese detalle, ya que todo va oculto y con formas redondeadas para evitar ese tipo de daños.  Finally, it should be noted that the different elements that make up the whole structure of the invention, do not have any of them cutting or traumatic air parts that by themselves and before a collision can injure, mutilate or cause death by that detail, since Everything goes hidden and with rounded shapes to avoid such damage.

DESCRIPCION DE LA FORMA DE REALIZACION PREFERIDA  DESCRIPTION OF THE PREFERRED EMBODIMENT

Considerando la numeración adoptada en las figuras, la estructura de valla guardarrail se determina a partir de unos cuerpos tubulares longitudinales 1 con una sección cerrada: ovoide, elíptica, oval, en forma de "D", de manera que el eje mayor 2 de estas secciones quedará dispuesto verticalmente para que el impacto de un vehículo contra tales cuerpos tubulares longitudinales 1 sea perpendicular a dicho eje mayor y conseguir así una mayor suavidad en el impacto dentro de lo que cabe.  Considering the numbering adopted in the figures, the guardrail fence structure is determined from longitudinal tubular bodies 1 with a closed section: ovoid, elliptical, oval, in the form of "D", so that the major axis 2 of these sections will be arranged vertically so that the impact of a vehicle against such longitudinal tubular bodies 1 is perpendicular to said major axis and thus achieve greater smoothness in the impact within what fits.

Los cuerpos tubulares longitudinales 1 pueden estar dispuestos en una sola alineación, dos o más, aunque lo más habitual serán dos alineaciones.  The longitudinal tubular bodies 1 can be arranged in a single alignment, two or more, although the most common will be two alignments.

Los cuerpos tubulares longitudinales 1 incorporan en su parte más baja un pliegue angular 3 o un pliegue arqueado 3' dirigido hacia el interior de tales cuerpos tubulares longitudinales 1. Dichos pliegues 3-3' ayudan a suavizar también el impacto durante la deformación de la estructura de valla de la invención.  The longitudinal tubular bodies 1 incorporate in their lower part an angular fold 3 or an arcuate fold 3 'directed towards the inside of such longitudinal tubular bodies 1. Said folds 3-3' also help soften the impact during the deformation of the structure of fence of the invention.

Los cuerpos tubulares longitudinales 1 se unen por sus extremos mediante unas piezas tubulares intermedias 4. Los cuerpos tubulares longitudinales 1 y piezas tubulares intermedias 4 se unen a unos postes anteriores 5 clavados en el suelo mediante unos amortiguadores mecánicos 6-6' que comprenden una parte envolvente 7 a modo de abrazadera abierta para fijarse a los postes anteriores mediante unos tornillos 9 y tuercas 10, y una parte posterior 8 que comprende unas piezas de lámina plegada constitutivas de los amortiguadores mecánicos propiamente dichos . The longitudinal tubular bodies 1 are joined at their ends by means of intermediate tubular parts 4. The longitudinal tubular bodies 1 and intermediate tubular parts 4 are attached to front posts 5 nailed to the ground by means of mechanical dampers 6-6 'comprising a wrapping part 7 as an open clamp to be fixed to the front posts by means of screws 9 and nuts 10, and a rear part 8 comprising folded sheet pieces constituting the mechanical shock absorbers themselves.

La parte anterior envolvente 7 de los amortiguadores mecánicos 6-6' cuenta con un par de aletas verticales 11 con orificios enfrentados por donde se introducirán los respectivos tornillos 9 asociados a las tuercas 10 respectivas para afianzar la fijación a tales postes anteriores 5.  The enveloping front part 7 of the mechanical shock absorbers 6-6 'has a pair of vertical fins 11 with facing holes through which the respective screws 9 associated with the respective nuts 10 will be introduced to secure the fixation to such anterior posts 5.

Las piezas tubulares intermedias 4 unen a los cuerpos tubulares longitudinales 1 mediante una conexión macho- hembra que se asegura con ayuda de unos elementos de anclaj e .  The intermediate tubular pieces 4 join the longitudinal tubular bodies 1 by means of a male-female connection that is secured with the help of anchoring elements e.

Para ello, uno de los extremos de las piezas tubulares intermedias 4 y uno de los extremos de los cuerpos tubulares longitudinales 1 cuentan con unos orificios pasantes 12 enfrentados con unas aberturas 13 establecidas en los extremos opuestos de los cuerpos tubulares longitudinales 1 y piezas tubulares intermedias 4.  To do this, one of the ends of the intermediate tubular pieces 4 and one of the ends of the longitudinal tubular bodies 1 have through holes 12 facing openings 13 established at opposite ends of the longitudinal tubular bodies 1 and intermediate tubular parts Four.

Alrededor de las aberturas 13 citadas existen unos rehundidos perimetrales 14 para albergar unas aletas perimetrales 15 que forman parte de unas tuercas móviles 16 alojadas en tales aberturas 13, de manera que una vez dispuestas las tuercas móviles 16 con sus aletas perimetrales 15 asentadas y ubicadas en los rehundidos 14 referidos se procede a encajar atornillando los extremos adyacentes de piezas tubulares intermedias 4 y cuerpos tubulares longitudinales 1 por machihembrado hasta que las tuercas móviles 16 queden enfrentadas con los orificios pasantes 12 correspondientes con esas piezas 4 y cuerpos tubulares longitudinales 1 para proceder a acoplar unos tornillos exteriores 17 que roscan en tales tuercas móviles 16 y aseguran la fijación entre los cuerpos tubulares longitudinales 1 y piezas tubulares intermedias 4. El desplazamiento de las tuercas móviles 16 facilita el acoplamiento de los tornillos exteriores 17 cuando los orificios pasantes 12 de los extremos de las piezas tubulares intermedias 4 y cuerpos tubulares longitudinales 1 no quedan enfrentados exactamente con los pasos roscados de las tuercas móviles 16. Around the aforementioned openings 13 there are perimeter recesses 14 to house perimeter fins 15 that are part of some mobile nuts 16 housed in such openings 13, so that once the mobile nuts 16 are arranged with their perimeter fins 15 seated and located in the recesses 14 referred to are proceeded to fit by screwing the adjacent ends of intermediate tubular pieces 4 and longitudinal tubular bodies 1 by tongue and groove until the mobile nuts 16 face the corresponding through holes 12 with those parts 4 and bodies longitudinal tubes 1 to proceed to fit outer screws 17 that thread in such mobile nuts 16 and ensure the fixing between the longitudinal tubular bodies 1 and intermediate tubular parts 4. The displacement of the mobile nuts 16 facilitates the coupling of the outer screws 17 when the through holes 12 of the ends of the intermediate tubular parts 4 and longitudinal tubular bodies 1 do not face exactly the threaded passages of the movable nuts 16.

Entre una alineación superior y una alineación inferior de cuerpos tubulares longitudinales 1 existe un estrecho hueco curvado 18 donde se ajusta una parte trasera de un perfil continuo 19 de material elástico con una superficie exterior reflectante 35 dispuesta en la parte adelantada de tal perfil continuo 19.  Between a top alignment and a bottom alignment of longitudinal tubular bodies 1 there is a narrow curved hollow 18 where a rear part of a continuous profile 19 of elastic material is fitted with a reflective outer surface 35 disposed at the leading part of such a continuous profile 19.

Los amortiguadores mecánicos 6-6' que se asocian a las piezas tubulares intermedias 4 cuentan con un par de alas horizontales 20 próximas entre si, entre las que se encaja una aleta intermedia 21 solidaria de las piezas tubulares intermedias 4, de manera que dicha aleta intermedia 21 y alas horizontales 20 se unen entre si mediante unos tornillos 9 y tuercas 10.  The mechanical dampers 6-6 'that are associated with the intermediate tubular parts 4 have a pair of horizontal wings 20 close to each other, between which an intermediate fin 21 integral with the intermediate tubular parts 4 is fitted, so that said fin intermediate 21 and horizontal wings 20 are joined together by screws 9 and nuts 10.

En cambio, cuando los cuerpos tubulares longitudinales 1 se asocian directamente con los postes anteriores 5 mediante los amortiguadores mecánicos 6' , éstos incorporan una pared frontal 22 afectada de un ranurado 23 para fijarse tales cuerpos tubulares longitudinales 1 mediante otros tornillos y tuercas.  On the other hand, when the longitudinal tubular bodies 1 are directly associated with the front posts 5 by means of the mechanical dampers 6 ', they incorporate an affected front wall 22 of a groove 23 to fix such longitudinal tubular bodies 1 by other screws and nuts.

También se han previsto unos reflectores unitarios 24 que se fijan sobre los propios cuerpos tubulares longitudinales 1.  Unit reflectors 24 are also provided which are fixed on the longitudinal tubular bodies 1.

La invención incorpora también unas piezas macizas 25 de material blando y elástico para reforzar las uniones que se ajustan en el interior de los cuerpos tubulares longitudinales 1 y piezas tubulares intermedias 4, contando tales piezas macizas con unos ranurados longitudinales 26 para el alojamiento de tuercas y cabezas de los tornillos. Dichas piezas macizas 25 cubren la totalidad del perímetro interno de los cuerpos tubulares longitudinales 1, no solo en las uniones entre éstos. Las medidas serían aproximadamente 90 cm, por lo que se colocarían cuatro piezas macizas 25 en cada tramo de cuerpo tubular longitudinal que posee 4 m, dejando un espacio libre entre ellos, para que no quede todo compacto. The invention also incorporates solid pieces 25 of soft and elastic material to reinforce the joints that fit inside the longitudinal tubular bodies 1 and intermediate tubular parts 4, counting such solid parts with longitudinal grooves 26 for housing nuts and screw heads. Said solid pieces 25 cover the entire internal perimeter of the longitudinal tubular bodies 1, not only at the joints between them. The measurements would be approximately 90 cm, so four solid pieces 25 would be placed in each section of longitudinal tubular body that has 4 m, leaving a free space between them, so that everything is not compact.

La estructura de la invención cuenta con un reforzamiento posterior de la estructura de valla guardarrail mediante unos postes posteriores 27 y unas vigas horizontales 28 que se vinculan a tales postes posteriores 27 mediante unas abrazaderas 29 unidas a los postes posteriores 27. A su vez, tales vigas horizontales 28 contactan con los postes anteriores 5, de manera que ante un impacto de un vehículo contra la estructura de valla, toda ella actúa conjuntamente incluyendo el reforzamiento posterior, muy efectivo éste ante el impacto de vehículos más pesados y de mayor tamaño como autobuses y camiones. Las abrazaderas 29 incorporan unas extensiones anteriores 30 afectadas de unas perforaciones 31 para facilitar la fijación de las vigas horizontales 28 con ayuda de elementos de fijación convencionales.  The structure of the invention has a subsequent reinforcement of the guardrail fence structure by means of rear posts 27 and horizontal beams 28 that are linked to such rear posts 27 by means of clamps 29 attached to the rear posts 27. In turn, such horizontal beams 28 contact the previous posts 5, so that in the event of an impact of a vehicle against the fence structure, all of it acts together including the subsequent reinforcement, which is very effective when faced with the impact of heavier and larger vehicles such as buses and trucks. The clamps 29 incorporate anterior extensions 30 affected by perforations 31 to facilitate the fixing of the horizontal beams 28 with the help of conventional fasteners.

Ese reforzamiento posterior se complementa además con una rejilla de protección 32 enmarcada por una barra perimetral 33 que se fija a los postes posteriores 27 mediante unas piezas semicirculares 34.  This rear reinforcement is further complemented by a protection grid 32 framed by a perimeter bar 33 that is fixed to the rear posts 27 by means of semicircular pieces 34.

Por último cabe señalar que algunas piezas tubulares intermedias 4 incorporan un corrugado perimetral 36.  Finally, it should be noted that some intermediate tubular pieces 4 incorporate a perimeter corrugated 36.

La invención incluye también unas piezas anulares 37- 37' que abrazan complementariamente a los cuerpos tubulares longitudinales 1 para fijar el guardarrail a un pilar o muro mediante unas pletinas perforadas 38 que forman parte de tales piezas anulares 37-37'.  The invention also includes annular pieces 37-37 'which additionally embrace the longitudinal tubular bodies 1 to fix the guardrail to a pillar or wall by means of perforated plates 38 that are part of such annular pieces 37-37'.
