Abstract
The invention relates to a reinforced flexible safety barrier for vehicle containment. The invention is designed to contain vehicles that lose control while travelling along a road. The invention consists of a longitudinal strip which is connected with anchors to metal supports that are positioned along the edge of the road, said strip comprising a undulating or non-undulating section (fig. 1) having a smooth or rough surface and round edges (fig. 1, r) and being produced from a material resulting from the recycling of end-of-life tyres (fig. 1, G). The interior of the aforementioned section is reinforced with metal straps (fig. 1, a) which render same resistant to traction in the event of vehicle impacts. The flexible nature of the barrier significantly reduces the seriousness of accidents as well as the damage caused to vehicles involved in accidents. The use of recycled material in the production of the barrier provides a considerable saving in relation to metal systems as well as improving the environment.

Description Description
BARRERA DE SEGURIDAD FLEXIBLE REFORZADA PARA CONTENCIÓN DE VEHÍCULOSREINFORCED FLEXIBLE SAFETY BARRIER FOR VEHICLE CONTAINMENT
[1] La invención se encuadra dentro de las técnicas de barreras de seguridad d eformables, utilizadas para garantizar y aumentar la Seguridad Vial de las carreteras, cumpliendo en todo momento las especificaciones técnicas establecidas en las disposiciones vigentes sobre la materia.[1] The invention is part of the safety barrier techniques that can be used to guarantee and increase the Road Safety of the roads, complying at all times with the technical specifications established in the current provisions on the subject.
[2] Las barreras de seguridad deformables se emplean con gran profusión en las redes de carreteras, mediante la utilización de bandas longitudinales en general de acero y con menor profusión, y solo para casos especiales, de madera simple o reforzada. Existen referencias de intentos de utilización de otros materiales, que no se han desarrollado en el mercado.[2] Deformable safety barriers are used with great profusion in road networks, by using longitudinal strips in general of steel and with less profusion, and only for special cases, of simple or reinforced wood. There are references to attempts to use other materials, which have not been developed in the market.
[3] El sistema propuesto consiste, en líneas generales, en la misma solución funcional que aportan las barreras metálicas, si bien la banda longitudinal que recibe los impactos (fig 2) de los vehículos se forma con material elástico procedente del reciclado de neumáticos (fig 1, G), reforzada mediante flejes de acero longitudinales (fig 1, a), que le confieren la resistencia a tracción necesaria para soportar las cargas de los impactos. La forma de la sección transversal podría adaptar diferentes formas y diseños y no sólo la tradicional bionda reflejada en la figs. 1 y 2.[3] The proposed system consists, in general, of the same functional solution provided by the metal barriers, although the longitudinal band that receives the impacts (fig 2) of the vehicles is formed with elastic material from tire recycling ( fig 1, G), reinforced by longitudinal steel strips (fig 1, a), which give it the tensile strength necessary to withstand impact loads. The shape of the cross section could adapt different shapes and designs and not just the traditional bionda reflected in figs. 1 and 2.
[4] La cuantía de estas armaduras interiores de acero (fig 1, a), se dispondrá en función de los niveles de contención deseados, con lo que será posible disponer de una gama de perfiles que permita una utilización óptima de los mismos en las diferentes situaciones con máximo nivel de contención, para donde se prevean consecuencias muy graves de un eventual accidente; nivel medio, para consecuencias graves; y nivel normal en los demás casos.[4] The amount of these inner steel reinforcements (fig 1, a), will be available depending on the desired containment levels, so it will be possible to have a range of profiles that allow optimum use of them in the different situations with maximum containment level, where very serious consequences of an eventual accident are anticipated; medium level, for serious consequences; and normal level in the other cases.
[5] Ello permitirá una economía en la cantidad de acero a utilizar, frente a las actuales soluciones de perfil único, dado que las altas cuantías que se utilizan no vienen condicionadas por la resistencia a tracción del perfil utilizado sino por su necesaria superficie para recibir los impactos. En el caso del perfil que se propone, la superficie la proporciona la banda continua de material elástico procedente del reciclado de neumáticos, y la resistencia a tracción, variable según el nivel de contención, la proporcionan los flejes de acero, con la cuantía adecuada a los diferentes niveles de contención.[5] This will allow an economy in the amount of steel to be used, compared to the current single profile solutions, since the high amounts used are not conditioned by the tensile strength of the profile used but by its necessary surface area to receive the impacts In the case of the proposed profile, the surface is provided by the continuous band of elastic material from tire recycling, and the tensile strength, variable according to the level of containment, is provided by steel strips, with the appropriate amount to the different levels of containment.
[6] Las barras longitudinales de goma reciclada que constituyen el sistema de contención, podrán llevar una malla textil o metálica (fig. 1, m) en el interior de la misma (fig. 1, Secc. A-A), a modo de armadura de piel, con objeto de reforzar la
cohesión de los dos materiales que la constituyen: la goma y el acero, impidiendo que durante un fuerte impacto, pueda 'abrirse' la goma y dejar al aire los flejes de acero que forman la armadura.[6] The longitudinal bars of recycled rubber that constitute the containment system may carry a textile or metal mesh (fig. 1, m) inside the same (fig. 1, Section AA), as a reinforcement of skin, in order to reinforce the cohesion of the two materials that constitute it: the rubber and the steel, preventing that during a strong impact, the rubber can be 'opened' and leave in the air the steel strips that form the armor.
[7] Al objeto de reforzar las zonas de mayor esfuerzo, cuales son las de amarres y de sujeción a los postes, podrán disponerse refuerzos de chapa continua (fig 2, R) para arriostrar los flejes entre sí y conectar todos ellos a los puntos de anclaje a los soportes.[7] In order to reinforce the areas of greatest effort, which are those of moorings and fastening to the posts, continuous sheet reinforcements (fig 2, R) may be arranged to brac the straps together and connect all of them to the points anchor to the supports.
[8] La sección transversal de la barrera, cuya geometría del eje podrá coincidir o no con las barreras metálicas convencionales, tendrá el espesor adecuado para resistir, junto con las armaduras metálicas, los impactos descritos en los ensayos a escala real correspondientes, de acuerdo con la norma Pr EN 1317 del Comité Europeo de Normalización, y dispondrán de bordes redondeados (fig 1. r) en los extremos de la sección transversal, de manera que no presente unas aristas que puedan producir efecto cortante en caso de accidente.[8] The cross-section of the barrier, whose axis geometry may or may not coincide with conventional metal barriers, will have the appropriate thickness to resist, together with the metal reinforcements, the impacts described in the corresponding real-scale tests, according to with the norm Pr EN 1317 of the European Committee for Standardization, and will have rounded edges (fig 1. r) at the ends of the cross section, so that it does not have edges that can produce a sharp effect in the event of an accident.
[9] Por otro lado, los extremos de las barras tendrán su corte biselado, o una unión tipo[9] On the other hand, the ends of the bars will have their bevel cut, or a joint type
'media madera', para permitir un mejor solape de los sucesivos tramos, y no presentar aristas vivas en el sentido de la circulación, (fig.2, b).'half wood', to allow a better overlap of the successive sections, and not to have sharp edges in the direction of the circulation, (fig.2, b).
[10] Los separadores entre las piezas longitudinales y los postes de soporte hincados al terreno, podrán ser los mismos utilizados para las barreras metálicas o se adaptarán a nuevas características de forma y resistencia de la nueva barrera elástica reforzada.[10] The spacers between the longitudinal pieces and the support posts driven to the ground may be the same as those used for metal barriers or they will adapt to new characteristics of shape and resistance of the new reinforced elastic barrier.
[11] El carácter elástico del material propuesto (caucho reciclado), presenta la ventaja de su mejor comportamiento frente al daño que producen los impactos, dada la menor rigidez del sistema frente a las soluciones al uso y su menor dureza superficial[11] The elastic nature of the proposed material (recycled rubber), has the advantage of its better performance against the damage caused by impacts, given the lower rigidity of the system compared to the solutions to use and its lower surface hardness
[12] Así es de prever que pequeños y medianos impactos de turismos con ángulo reducido de incidencia, o velocidades en las gamas más bajas, puedan saldarse sin daño alguno, tanto para el vehículo como para el propio sistema de contención.[12] Thus it is expected that small and medium impacts of passenger cars with reduced angle of incidence, or speeds in the lower ranges, can be settled without any damage, both for the vehicle and for the containment system itself.
[13] De la misma manera, en impactos de mayor envergadura, puede esperarse una reducción de la gravedad de los mismos, respecto a los sistemas tradicionales, dada la mayor capacidad de la barrera elástica para realizar una disipación de las energías del impacto con una menor violencia, por su carácter elástico.[13] In the same way, in larger impacts, a reduction in their severity can be expected, compared to traditional systems, given the greater capacity of the elastic barrier to dissipate impact energies with a less violence, due to its elastic character.
[14] También son de destacar las ventajas de tipo medioambiental de la Barrera Flexible[14] The environmental advantages of the Flexible Barrier are also noteworthy
Reforzada, dada la utilización de Neumáticos Fuera de Uso (NFUs) en la fabricación de este nuevo perfil.Reinforced, given the use of Tires Out of Use (NFUs) in the manufacture of this new profile.
[15] La aplicación industrial de este producto es evidente, posibilitando una alternativa a la solución metálica actual, cuyo mercado casi monopolístico y los precios alcanzados por el acero, le confieren un alto coste.[15] The industrial application of this product is evident, enabling an alternative to the current metal solution, whose almost monopolistic market and the prices reached by steel, give it a high cost.
[16] La solución que aporta este sistema de contención de vehículos, mediante perfiles reforzados de goma, procedente del reciclado de neumáticos, aparte de un menor coste, aporta un más sencillo montaje; un menor mantenimiento; una mayor seguridad para la
circulación; y una disminución de la gravedad de los accidentes y de los daños en ellos generados.
[16] The solution provided by this vehicle containment system, through reinforced rubber profiles, from tire recycling, apart from a lower cost, provides a simpler assembly; less maintenance; greater security for the circulation; and a decrease in the severity of the accidents and the damages generated in them.
