Description
Estructura de transición.Transition structure.
El objeto de la presente invención es un sistema de retención con una estructura de transición entre dos sistemas distintos de retención en carreteras, presentando los sistemas de retención flexibilidades diferentes.The object of the present invention is a system retention with a transition structure between two systems different from road retention, presenting the systems of retention of different flexibilities.
Los sistemas de retención en calles están sujetos al documento DIN EN 1317-2 de 1998 en el que se establecen distintas clases de prestaciones y procedimientos de prueba. Fuera de sistemas de retención de metal, en particular carriles protectores, han probado su eficacia también semejantes de hormigón.Street retention systems are subject to DIN EN 1317-2 of 1998 in which different kinds of benefits and procedures are established proof. Outside metal retention systems, in particular protective rails, have proven their effectiveness also similar to concrete.
Especialmente ha probado su eficacia el sistema escalonado de retención según el documento EP A-1 293 610. Más allá se aseguran todavía considerables recorridos de carreteras nacionales, autovías y autopistas con la ayuda de sistemas de retención de metal.The system has especially proven its effectiveness retention step according to EP A-1 293 610. Beyond that, considerable paths are still ensured national roads, highways and highways with the help of metal retention systems.
Es crítica la transición de un sistema de retención a otro, en particular cuando éstos presentan diferente flexibilidad.The transition of a system of retention to another, particularly when they present differently flexibility.
En la norma provisional DIN V ENV 1317-4 se prescribe en que casos las estructuras de transición deben satisfacer determinadas exigencias, y además deben supeditarse a una costosa prueba. Cuando ambos sistemas de retención están hechos de hormigón solo es necesaria una prueba si la flexibilidad difiere una de otra en dos escalones. En transiciones de hormigón a acero ya es necesaria una prueba cuando solo existe una diferencia de un escalón de flexibilidad.In the provisional standard DIN V ENV 1317-4 is prescribed in which cases the structures of transition must meet certain requirements, and must also subject to an expensive test. When both retention systems they are made of concrete only one test is necessary if the Flexibility differs from one another in two steps. In transitions from concrete to steel a test is necessary when there is only a difference of a flexibility step.
En el documento
DE-A-37 42 356 se describe una
estructura de transición para vías de comunicación de un elemento
de retención de hormigón sobre una valla protectora formada por un
pilar de metal aproximadamente vertical y al menos por un larguero
de metal aproximadamente horizontal. En la zona de transición entre
el sistema de retención de hormigón y la valla protectora de metal
se solapan los dos sistemas de retención. Entre la valla protectora
y el sistema de retención de hormigón están previstos tubos
verticales con diámetros diferentes. Debe producirse una absorción
de energía por los tubos durante el choque de un vehículo. En este
caso se trata de una estructura relativamente costosa ya que la
posición de los tubos individuales debe estar definida de forma
clara. Además, se ha mostrado que no puede obtener la transición
difusa deseada en la flexibilidad con este
sistema.Document DE-A-37 42 356 describes a transition structure for communication paths of a concrete retention element on a protective fence formed by an approximately vertical metal pillar and at least one approximately horizontal metal stringer. The two retention systems overlap in the transition zone between the concrete retention system and the metal protective fence. Vertical pipes with different diameters are provided between the protective fence and the concrete retention system. There must be an absorption of energy by the tubes during the crash of a vehicle. In this case it is a relatively expensive structure since the position of the individual tubes must be clearly defined. In addition, it has been shown that you cannot obtain the desired diffuse transition in flexibility with this
system.
Por consiguiente, existe además la desventaja de que pueden producirse graves accidentes en la transición entre dos sistemas de retención de diferente flexibilidad, si un vehículo choca en la zona de transición contra el sistema de retención. En este caso puede producirse en particular un tipo de formación de rampas mediante las que puede hacerse derrapar un vehículo por la calzada.Therefore, there is also the disadvantage of that serious accidents can occur in the transition between two retention systems of different flexibility, if a vehicle collides in the transition zone against the retention system. In in this case, in particular, a type of formation of ramps through which a vehicle can be skidded by the road.
La invención tiene el objetivo de conseguir un sistema de retención con una estructura de transición entre dos sistemas de retención de diferente flexibilidad con el que pueda conseguirse de forma sencilla una transición segura.The invention aims to achieve a retention system with a transition structure between two retention systems of different flexibility with which you can easily achieve a safe transition.
La solución del objetivo se realiza según la invención por las características de la reivindicación 1.The solution of the objective is carried out according to the invention according to the characteristics of claim 1.
Según la invención esto se realiza gracias a que los sistemas de retención están unidos entre sí de manera ensamblada, y el sistema de mayor flexibilidad presenta en el lado opuesto a la calzada varios elementos amortiguadores que reducen la flexibilidad por secciones.According to the invention this is done because retention systems are linked together so assembled, and the system of greater flexibility presents on the side opposite the road several damping elements that reduce the flexibility by sections.
Por consiguiente, según la invención los elementos amortiguadores presentan en la zona de transición entre los dos sistemas de retención un efecto amortiguador diferente. En este caso, el efecto amortiguador de los elementos amortiguadores individuales disminuye a partir del sistema de retención de menor flexibilidad en dirección al sistema de retención de mayor flexibilidad. En este caso la zona de transición es aquella zona en la que la flexibilidad se varía a partir del un sistema de retención al otro sistema de retención. Preferiblemente está previsto en la zona de transición el sistema de retención de mayor flexibilidad, como por ejemplo, valla protectora de acero, es decir, se extiende hasta el sistema de retención de menor flexibilidad, como por ejemplo, elementos de retención de hormigón, aumentándose o disminuyéndose gradualmente la flexibilidad en la zona de transición mediante la previsión de, en particular, elementos amortiguadores dispuestos en el lado opuesto a la calzada.Accordingly, according to the invention the damping elements present in the transition zone between the two retention systems have a different damping effect. In In this case, the damping effect of the damping elements individual decreases from the minor retention system flexibility towards greater retention system flexibility. In this case the transition zone is that zone in that flexibility is varied from a retention system to the other retention system. It is preferably provided in the transition zone the most flexible retention system, as for example, protective steel fence, that is, extends to the less flexible retention system, as per example, concrete retaining elements, increasing or gradually decreasing flexibility in the area of transition by forecasting, in particular, elements shock absorbers arranged on the opposite side of the road.
Para los elementos amortiguadores se trata preferiblemente de elementos de colada de hormigón o similares, que en particular están puestos directamente sobre una cara superior de calzada sin anclaje. El efecto amortiguador de los elementos amortiguadores individuales depende según la invención de la inercia de masas. Especialmente preferible es en este caso que los elementos de colada de hormigón o los elementos amortiguadores presenten la misma altura y por ello se varíe la inercia de masas por el cambio de la anchura o profundidad.For the damping elements it is preferably of concrete casting elements or the like, which in particular they are placed directly on an upper face of road without anchor. The damping effect of the elements individual dampers depends on the invention of inertia of masses Especially preferable is in this case that concrete casting elements or damping elements have the same height and therefore the mass inertia is varied by changing the width or depth.
La altura de los elementos amortiguadores individuales corresponde preferiblemente al menos a la altura del sistema de retención de mayor flexibilidad. Esto es en este sentido ventajoso ya que el sistema de retención de mayor flexibilidad se deforma durante un choque de un vehículo o similares, y por consiguiente está garantizado que, por ejemplo, la valla protectora de metal se presiona contra los elementos amortiguadores y la valla protectora no patina sobre los elementos amortiguadores.The height of the damping elements individual preferably corresponds at least to the height of the retention system for greater flexibility. This is in this regard. advantageous since the more flexible retention system is warps during a crash of a vehicle or the like, and by consequently it is guaranteed that, for example, the protective fence Metal is pressed against the damping elements and the fence protective does not slip on the damping elements.
Los elementos amortiguadores están fabricados preferiblemente de partes cada vez más cortas del sistema de retención con la menor flexibilidad. Cuanto más cortas son las partes del sistema de retención con la menor flexibilidad, es decir, el sistema de retención de hormigón o hormigón armado, más fácilmente pueden desplazarse lateralmente, ya que no están ancladas en el hormigón, sino sólo están puestas sobre el suelo. Mediante la estructura de transición según la invención del sistema con la menor flexibilidad respecto al sistema con la mayor flexibilidad, como por ejemplo, una valla protectora de metal, se realiza por consiguiente una transición esencialmente sin escalones.The damping elements are manufactured preferably of increasingly shorter parts of the system retention with the least flexibility. The shorter the parts of the retention system with the least flexibility, is that is, the concrete or reinforced concrete retention system, more they can easily move laterally, since they are not anchored in concrete, but are only laid on the ground. Through the transition structure according to the invention of the system with the least flexibility with respect to the system with the greatest flexibility, such as a metal protective fence, is therefore make a transition essentially without steps
Los elementos amortiguadores individuales no están unidos preferiblemente entre sí. En particular, elementos amortiguadores semejantes presentan una distancia de 5 - 50 cm. En este caso es especialmente ventajoso que la distancia entre los elementos amortiguadores adyacentes aumente en la dirección del sistema de retención de mayor flexibilidad. Mediante la previsión de distancias semejantes está garantizado el corrimiento querido de los elementos amortiguadores individuales sobre la superficie de calzada por el que se origina la amortiguación.The individual damping elements do not They are preferably joined together. In particular, elements Similar dampers have a distance of 5 - 50 cm. In this case is especially advantageous that the distance between adjacent damping elements increase in the direction of the retention system for greater flexibility. Through the forecast from similar distances the desired run of the individual damping elements on the surface of roadway where the damping originates.
Mientras, por ejemplo, el sistema de retención según el documento EP-A-1 293 610 está unido entre sí en recorridos largos y por ello solo puede desplazarse lateralmente por cargas muy fuertes, partes más cortas fabricadas del mismo material pueden desplazare más fácilmente. Si éstas se fijan detrás del carril metálico o la valla protectora de la estructura colindante de acero de elevada flexibilidad, conducen a una mayor flexibilidad por secciones o casi sin escalones hasta la zona en la que solo está previsto todavía el sistema con la mayor flexibilidad.While, for example, the retention system according to EP-A-1 293 610 is linked to each other on long journeys and therefore can only move laterally through very strong loads, shorter parts made of the same material can move more easily. Yes these are fixed behind the metal rail or the protective fence of the adjoining steel structure of high flexibility, lead to greater flexibility by sections or almost no steps up to the area in which only the system with the largest flexibility.
Evidentemente este principio constructivo puede aplicarse también para la transición de un sistema flexible a un sistema menos flexible. Luego, se prevén al final del sistema con la mayor flexibilidad elementos amortiguadores cada vez más largos del sistema con la menor flexibilidad, hasta el punto en el que los dos sistemas están unidos entre sí directamente de manera ensamblada.Obviously this constructive principle can apply also for the transition from a flexible system to a less flexible system Then, they are foreseen at the end of the system with the greater flexibility increasingly longer shock absorbers of the system with the least flexibility, to the point where the two systems are linked together directly so assembled
Por consiguiente se trata de una estructura sencilla que puede introducirse generalizadamente después de ensayos previos correspondientes y puede limitar los tests muy caros a unos pocos ensayos previos.Therefore it is a structure simple that can be introduced generally after rehearsals corresponding prior and can limit very expensive tests to about few previous trials.
La estructura de transición según la invención presenta en particular la ventaja de que puede determinar la longitud óptima de la estructura de transición y el dimensionamiento, así como, el posicionamiento de los elementos amortiguadores por ensayos previos con sistemas habituales de retención. Luego, en copias posteriores es posible calcular éstas en base a los ensayos previos, de forma que no es necesaria ninguna nueva prueba más.The transition structure according to the invention it has in particular the advantage that it can determine the optimal length of the transition structure and the sizing, as well as, the positioning of the elements dampers by previous tests with usual systems of retention. Then, in later copies it is possible to calculate these based on previous tests, so that no New test more.
A continuación se explica detalladamente la invención mediante una forma de realización preferida en referencia a los dibujos adjuntos.The following explains in detail the invention by a preferred embodiment in reference to the attached drawings.

Un sistema de retención de baja flexibilidad presenta en el ejemplo de realización representado varios elementos de retención de hormigón 10 puestos uno junto a otros sobre la superficie de calzada. En este caso puede tratarse, por ejemplo, de elementos de retención de la solicitante con la referencia Safetybaer H2 o Safetybaer H4.A low flexibility retention system presents in the embodiment shown several elements concrete retention 10 positions next to each other on the road surface. In this case it can be, for example, retention elements of the applicant with the reference Safetybaer H2 or Safetybaer H4.
Un sistema de retención de mayor flexibilidad presenta dos largueros de valla protectora 12 o vallas protectoras de metal en el ejemplo de realización representado. Los dos largueros de valla protectora 12 recubren al menos parcialmente el, respecto a una zona de transición 14, primer elemento de retención 10. Para ello presenta el elemento de retención 10 una hendidura 16. La hendidura 16 está configurada de forma que corresponde esencialmente a la profundidad del larguero de valla protectora, de forma que ésta no sobresale frente a una cara frontal 18 del elemento de retención 10. Los dos largueros de valla protectora 12 están unidos, por ejemplo, atornillados con el elemento de retención 10 en la zona de la hendidura 16.A retention system with greater flexibility features two stringers of protective fence 12 or protective fences metal in the embodiment shown. Both protective fence stringers 12 at least partially cover the, with respect to a transition zone 14, first retention element 10. For this purpose, the retaining element 10 has a groove. 16. Slot 16 is configured accordingly essentially at the depth of the protective fence stringer, of so that it does not protrude in front of a front face 18 of the retaining element 10. The two stringers of protective fence 12 are attached, for example, screwed with the element of retention 10 in the groove area 16.
En la zona de transición 14 están previstos varios elementos amortiguadores 20 en el lado opuesto a la calzada detrás de los largueros de valla protectora 12. Los elementos amortiguadores 20a - 20i individuales presentan un efecto amortiguador diferente. Para la reducción de los costes de fabricación, la configuración exterior de forma o la sección de los elementos amortiguadores 20 corresponde a la forma del elemento de retención 10. La anchura de los elementos amortiguadores 20 disminuye a partir del elemento amortiguador 20a, que está dispuesto directamente junto al elemento de retención 10 de baja flexibilidad, hacia el elemento de retención 20i. En el ejemplo de realización, el elemento de retención 20i es el último elemento amortiguador más estrecho al que luego se une el elemento de retención de elevada flexibilidad.In transition zone 14 are planned several shock absorbers 20 on the opposite side of the road behind the stringers of protective fence 12. The elements individual 20a - 20i dampers have an effect different shock absorber For the reduction of the costs of manufacturing, exterior shape configuration or section of the damping elements 20 corresponds to the shape of the element of retention 10. The width of the damping elements 20 decreases from the damping element 20a, which is arranged directly next to the retention element 10 of withdrawal flexibility, towards the retention element 20i. In the example of embodiment, the retention element 20i is the last element narrower shock absorber to which the element of high flexibility retention.
Los elementos amortiguadores 20a - 20i individuales están dispuestos sobre una cimentación de forma que los elementos amortiguadores 20a - 20i pueden desplazarse durante un choque de un vehículo en la zona de transición 14 en dirección de una flecha 22 (fig. 1).The shock absorbers 20a - 20i individual are arranged on a foundation so that the damping elements 20a - 20i can move during a crash of a vehicle in transition zone 14 in the direction of an arrow 22 (fig. 1).
Un desplazamiento de los elementos (20a - 20i) se realiza sobre una superficie superior (28) de una cimentación. Para la cimentación puede tratarse, por ejemplo, de unos cimientos de hormigón o similares.A displacement of the elements (20a - 20i) it is performed on an upper surface (28) of a foundation. For the foundation it can be, for example, a foundation of concrete or similar.
Para evitar un atasco o bloqueo de elementos amortiguadores 20a - 20i adyacentes éstos están dispuestos unos respecto a otros cada vez a una distancia 24.To avoid a jam or blockage of items adjacent 20a - 20i shock absorbers these are arranged about with respect to others each time at a distance 24.
