Description
Nuevo sistema para protección de los guardarraíles utilizando para ello tela de hormigón, dotando a los guardarraíles ya existentes de una gran seguridad para motoristas y ciclistas.New system for protection of guardrails using concrete fabric, providing the existing guardrails of great safety for motorists and Cyclists
La presente invención se refiere a un sistema para proteger a los motoristas o ciclistas que proporciona una gran seguridad a los motoristas o ciclistas accidentados que son despedidos hacia el arcén, evitando su impacto contra los soportes de los guardarraíles o "quitamiedos" y absorbiendo energía del impacto. El sistema se puede instalar en los guardarraíles existentes con gran rapidez y bajo coste.The present invention relates to a system to protect motorcyclists or cyclists that provides a great safety to motorcyclists or rugged cyclists who are dismissed towards the shoulder, avoiding its impact against the supports of the guardrails or "quitamiedos" and absorbing energy from impact. The system can be installed in the guardrails existing very quickly and at low cost.
La invención se encuadra dentro del campo de la Seguridad Vial.The invention falls within the field of Road safety.
Desde hace años, conscientes de los daños que sufrían estos usuarios de la carretera, se han diseñado diversos sistemas.For years, aware of the damages that these road users suffered, various designs have been designed systems.
Se aconseja por la Administración Estatal la instalación de postes verticales en forma de "C" para nuevas carreteras o para la reparación de los tramos antiguos. Existen también varias patentes que disponen en los postes existentes un revestimiento protector, como puede ser la Patente Española P200102355.It is advised by the State Administration the installation of vertical "C" shaped posts for new roads or for the repair of the old sections. exist also several patents that have in the existing posts a protective coating, such as the Spanish Patent P200102355.
Los sistemas anteriores mejoran el comportamiento en los guardarraíles frente a motoristas en que el impacto se produce contra un poste sin aristas, pero no se evita el daño que puede causar el choque contra esa superficie; como tampoco impide posibles cortes con la chapa de protección horizontal o que el cuerpo se cuele entre en espacio existente entre la bionda y el asfalto, pudiendo entonces colisionar contra otros obstáculos, pasar a la vía de dirección contraria o caer por una pendiente.The previous systems improve the behavior in the guardrails in front of motorcyclists in which the impact occurs against a post without edges, but the damage that collision can cause against that surface; as neither prevents possible cuts with the horizontal protection plate or that the body slips between the space between the bionda and the asphalt, then being able to collide against other obstacles, pass to the opposite direction or fall down a slope.
Se conocen otras patentes que aportan soluciones a los problemas anteriores, instalando en la zona abierta del guardarraíl una pantalla continua en la que impacte el accidentado, impidiendo que salga de la carretera. Como ejemplo de estos sistemas citamos la Patente española P200500537 que consiste en una banda longitudinal de goma, fabricada con neumáticos reciclados, que se monta en los postes verticales presentando un separador elástico entre ellos y la pantalla. El Modelo de Utilidad español U200801527 reivindica un elemento modular que cubre el hueco entre la blonda y el asfalto, mediante un cuerpo longitudinal de material flexible y hueco para configurar en su interior una cámara de aire, evitando que tras el impacto el cuerpo pase al otro lado del guarda-raíl. El montaje se realiza colocando soportes en la parte interna de la bionda y en el poste vertical.Other patents that provide solutions are known to the above problems, installing in the open area of the keep a continuous screen on which the injured person impacts, preventing him from leaving the road. As an example of these systems We cite the Spanish Patent P200500537 which consists of a band longitudinal rubber, made from recycled tires, which mounted on vertical posts presenting an elastic separator Between them and the screen. The Spanish Utility Model U200801527 claims a modular element that covers the gap between the lace and the asphalt, through a longitudinal body of flexible material and hollow to configure inside an air chamber, avoiding that after the impact the body passes to the other side of the rail guard. The assembly is done by placing brackets on the inside of the bionda and on the pole vertical.
El problema que presentan los anteriores documentos es la complejidad en la fabricación e instalación del dispositivo que reivindican, es que en algunos casos requieren el desmontaje de la bionda para el anclaje de esta protección, resultando soluciones muy costosas económicamente de instalar.The problem presented by the above documents is the complexity in the manufacture and installation of device they claim is that in some cases they require the disassembly of the bionda for anchoring this protection, resulting very economically expensive solutions to install.
Otro inconveniente que presentan algunos de los sistemas que consisten en la incorporación de bandas longitudinales en los huecos del guarda-raíl, es que no garantizan que el accidentado no vuelva a la vía por efecto rebote tras chocar contra la pantalla; ello implica un riesgo de ser atropellado por los vehículos que le siguen.Another drawback presented by some of the systems consisting of the incorporation of longitudinal bands in the gaps of the rail guard, they don't guarantee that the injured person does not return to the track due to the rebound effect after crashing against the screen; this implies a risk of being hit by the vehicles that follow.
Existe también la instalación de una banda de material textil que se emplea para cubrir el vano entre el guarda-raíl y el suelo, P200503054, confeccionada por hilos de distintos materiales, que se asegura superiormente la lámina en la zona retraída del perfil ondulado de la bionda, por su zona exterior. También el Modelo de Utilidad español U200001969 presenta una franja de material textil conformado por fibras de poliéster recubiertas de P.V.C., y que se atornilla a los postes verticales.There is also the installation of a band of textile material used to cover the gap between the rail and floor guard, P200503054, ready made by threads of different materials, which ensures superiorly the sheet in the retracted area of the wavy bionda profile, due to its Outside area. Also the Spanish Utility Model U200001969 it presents a strip of textile material made up of fibers of polyester coated with P.V.C., and screwed to the posts vertical
Las láminas o bandas textiles elásticas embolsan el cuerpo evitando que rebote en la vía, pero el inconveniente es que la composición de esta barrera la hace muy sensible a los rayos ultravioleta, con una vida útil de cinco años, debiendo procederse a la instalación de otra banda textil tras este tiempo.Elastic textile sheets or bands pocket the body preventing it from bouncing on the track, but the drawback is that the composition of this barrier makes it very sensitive to lightning ultraviolet, with a useful life of five years, and must proceed to the installation of another textile band after this time.
En último lugar aparece la patente de invención ES 2 320 968 A1, que resuelve el problema mediante una malla y unos cables superior e inferior, con el consiguiente problema de posibles sabotajes (rompiendo la malla), así como problemas derivados de los cables tensos en el momento del impacto, latigazos, etc...The invention patent appears last ES 2 320 968 A1, which solves the problem through a mesh and some upper and lower cables, with the consequent problem of possible sabotage (breaking the mesh), as well as problems derived from tense cables at the moment of impact, lashes, etc ...
La presente invención propone colocar una tela de hormigón bajo el guardarraíl y a lo largo de este para la protección de motoristas o ciclistas. Esta tela se extiende bajo el guardarraíl y se conforma con la sección transversal más adecuada según definan los ensayos de homologación. Una vez colocada la tela, se riega con agua. El hormigón endurece a las dos horas de modo que el dispositivo queda con la forma definitiva.The present invention proposes to place a cloth of concrete under the guardrail and along this for the protection of motorcyclists or cyclists. This fabric extends under the guardrail and conforms to the most appropriate cross section as defined by the approval tests. Once the fabric is placed, Water with water. The concrete hardens at two hours so that The device is in the final form.
\newpage\ newpage
En caso de resultar necesario, se realizarán perforaciones en la tela antes del regado con el objeto de mejorar las características mecánicas.If necessary, they will be carried out perforations in the fabric before watering in order to improve The mechanical characteristics.
Esta invención constituye un elemento de protección óptimo que ante el impacto de un motorista, canaliza al mismo a lo largo del dispositivo y evita que pase al otro lado del guardarraíl. Las características resistentes dispositivo imposibilitan el paso del motociclista entre el dispositivo y el suelo o entre el dispositivo y el guarda raíl.This invention constitutes an element of optimal protection that, before the impact of a motorist, channels same along the device and prevents it from passing to the other side of the guardrail The device resistant features make it impossible for the motorcyclist to pass between the device and the ground or between the device and the rail guard.
La parte superior de la tela se coloca por encima de la parte inferior y a lo largo del guardarraíl, por lo que impide el contacto del motorista con el mismo.The upper part of the fabric is placed by above the bottom and along the guardrail, so prevents contact of the biker with it.

La resistencia a la flexión la confiere la propia tela una vez endurecida, por lo que al no ser necesario añadir piezas, no aparecen elementos duros o posibles puntos que pudieran seccionar miembros.The flexural strength is conferred by the own fabric once hardened, so not being necessary add pieces, hard elements or possible points that do not appear They could section members.
El elemento se conforma "in situ", dependiendo de la altura del guardarraíl, de modo que la parte inferior del mismo quede adosada al suelo cubriendo las distintas alturas que se presenten, como consecuencia de recrecimientos, degradación de la carretera, etc. Puesto que lo más probable al incidir el cuerpo, es que llegue deslizándose por el suelo, al quedar la parte inferior del dispositivo adosada al suelo, se evita que el cuerpo del motorista pueda colarse por debajo del elemento y golpee contra algún poste.The element is shaped " in situ ", depending on the height of the guardrail, so that the lower part of it is attached to the ground covering the different heights that occur, as a result of re-growth, degradation of the road, etc. Since it is most likely to affect the body, it is sliding along the ground, as the bottom of the device is attached to the ground, it is avoided that the body of the biker can sneak under the element and hit a post.
Finalmente, los medios de fijación a los postes del guardarraíl comprenden una pieza de unión entre dicho elemento y el poste, estando concebida dicha pieza de unión de modo que se deforma plásticamente cuando un motorista impacta sobre dicha superficie mayor frontal del elemento, de modo que se hace aún más inelástico el impacto y por lo tanto, menor es el ángulo de rebote del cuerpo y menos trayecto recorre éste.Finally, the fixing means to the posts of the guardrail comprise a connecting piece between said element and the post, said connecting piece being designed so that deforms plastically when a motorist impacts on said larger front surface of the element, so that it becomes even more inelastic the impact and therefore, the smaller the bounce angle of the body and less path travels this one.
Para mejor comprensión de cuanto se ha expuesto se acompañan unos dibujos en los que esquemáticamente y tan sólo a título de ejemplo no limitativo, se representan tres casos de realización.For a better understanding of how much has been exposed some drawings are accompanied in which schematically and only to non-limiting example title, three cases of realization.
La figura 1 es una vista en sección de un elemento de protección dispuesto bajo un guardarraíl a la altura de los postes, según una realización preferida de la invención.Figure 1 is a sectional view of a protective element arranged under a guardrail at the height of the posts, according to a preferred embodiment of the invention.
La figura 2 es una vista en sección de un elemento de protección dispuesto bajo un guardarraíl en el centro del vano, según una realización preferida de la invención.Figure 2 is a sectional view of a protective element arranged under a guardrail in the center of the span, according to a preferred embodiment of the invention.
La figura 3 es una vista en perspectiva del elemento de la invención dispuesto bajo un guardarraíl, por el lado de la superficie de impacto.Figure 3 is a perspective view of the element of the invention arranged under a guardrail, on the side of the impact surface.
La figura 4 es una vista en perspectiva del elemento de la invención dispuesto bajo un guardarraíl, desde la parte posterior.Figure 4 is a perspective view of the element of the invention arranged under a guardrail, from the back.
La invención se refiere a un sistema 1 de protección para motoristas o ciclistas (SPM) destinado a ser dispuesto bajo el guardarraíl 4 y a lo largo de este según una dirección longitudinal L.The invention relates to a system 1 of protection for motorcyclists or cyclists (SPM) intended to be arranged under guardrail 4 and along this according to a longitudinal direction L.
El elemento de la invención comprende un cuerpo 1 longitudinal de tela de hormigón (esta tela es una lámina compuesta formada por PVC hormigón fibras predosificado en seco y una malla de fibras), medios de fijación 2 y 3 a los postes 5 del guardarraíl 4. Según se defina en los ensayos de homologación, se determinará la sección transversal del cuerpo 1 de manera que se produzca una acanaladura que provoque un desplazamiento del motorista en el momento del impacto a lo largo del sistema de protección.The element of the invention comprises a body 1 longitudinal concrete fabric (this fabric is a sheet Composite formed by PVC concrete dry pre-dosed fibers and a fiber mesh), fixing means 2 and 3 to posts 5 of the guardrail 4. As defined in the approval tests, determine the cross section of body 1 so that it produce a groove that causes a displacement of the motorcyclist at the time of impact along the system protection.
Para contribuir a evitar que el cuerpo del motorista se cuele entre el elemento y el guardarraíl la parte superior del dispositivo se coloca por encima de la parte inferior del guardarraíl y sobresale de ésta unos centímetros a lo largo del elemento. Evidentemente, cuando el elemento está montado bajo un guardarraíl, dicha zona queda enfrentada, tal como se aprecia en la figura 2, contra el guardarraíl. Así, cuando un motorista impacta contra el elemento, ésta evita que el extremo lateral superior del elemento pase al otro lado del guardarraíl, y garantiza una continuidad en vertical entre el guardarraíl y el elemento de protección.To help prevent the body from biker sneaks between the element and the guardrail the part top of the device is placed above the bottom of the guardrail and protrudes from it a few centimeters along the element. Obviously, when the element is mounted under a guardrail, this area is facing, as seen in the Figure 2, against the guardrail. So, when a motorist impacts against the element, it prevents the upper side end of the element pass to the other side of the guardrail, and guarantees a vertical continuity between the guardrail and the element of protection.
Tal como se puede apreciar en las figuras 1 y 2, la superficie frontal 1 del elemento está abombada hacia el interior del elemento 1, de modo que contribuiría a canalizar el cuerpo del motorista.As can be seen in figures 1 and 2, the front surface 1 of the element is domed inwards of element 1, so that it would contribute to channeling the body of biker
