Description

SOPORTE PARA PROTECCIONES QUITAMIEDOS DE CARRETERAS  SUPPORT FOR ROAD REMOVAL PROTECTIONS
DESCRIPCIÓN DESCRIPTION
OBJETO DE LA INVENCION OBJECT OF THE INVENTION
La presente invención se refiere a un soporte para protecciones quitamiedos de carreteras. The present invention relates to a support for road guard protections.
ANTECEDENTES DE LA INVENCION BACKGROUND OF THE INVENTION
Se conocen en la ingeniería civil unas barreras de protección contra la salida de vehículos en carceleras con el fin de proteger contra caldas por terraplenes o invasión de otras vías. Estas barreras comprenden una serie de soportes en cuya parte superior se monta un perfil continuo. Dicho perfil tiene generalmente forma de doble onda, razón por la que a estas barreras se las conoce como biondas. Civil protection barriers are known in civil engineering against the exit of vehicles in jails in order to protect against broths by embankments or invasion of other roads. These barriers comprise a series of supports in whose upper part a continuous profile is mounted. This profile is generally in the form of a double wave, which is why these barriers are known as biondas.
Estas barreras ofrecen una buena protección, razón por la cual están profusamente extendidas por la red viaria. Sin embargo, se viene manifestando un problema con su utilización, consistente en que los soportes de dichas barreras, que en la actualidad son perfiles laminados de sección en I, causan lesiones graves en caso de colisión directa con el cuerpo de una persona proyectada contra dicho soporte. Foresta razón los motoristas son un colectivo muy perjudicado en este tipo de accidentes. These barriers offer good protection, which is why they are profusely extended by the road network. However, a problem has been manifested with its use, consisting of the fact that the supports of these barriers, which are currently laminated I-section profiles, cause serious injuries in case of direct collision with the body of a person projected against said support. Foresta reason the motorists are a group very damaged in this type of accidents.
Para intentar solucionar este problema se ha intentado proteger los soportes con elementos deformables, típicamente tubulares, pero dado que los postes están sólidamente fijados al suelo mediante cimentación para resistir la gran energía de la colisión de un vehículo, el choque de un cuerpo contra los mismos siempre va a sufrir una grave lesión, habiendo únicamente eliminado en parte las protecciones existentes los seccionamientos parciales del cuerpo al cubrir las aristas del perfil del soporte, pero sin evitar que aun asi se ocasionen gravísimas lesiones. To try to solve this problem, we tried to protect the supports with deformable elements, typically tubular, but since the posts are solidly fixed to the ground by foundation to resist the great energy of the collision of a vehicle, the collision of a body against them you will always suffer a serious injury, having only partially removed the existing protections partial sectioning of the body when covering the edges of the support profile, but without preventing even serious injuries.
DESCRIPCION DE LA INVENCION DESCRIPTION OF THE INVENTION
El soporte para protecciones quitamiedos de carreteras de la invención tiene una configuración que permite su desmembramiento en caso de colisión directa con el mismo, pero manteniendo la soiidez del soporte en caso de colisión de un vehículo con el perfil continuo superior, sea bionda o no. The support for road guard protections of the invention has a configuration that allows its dismemberment in the event of a direct collision with it, but maintaining the solidity of the support in the event of a vehicle collision with the upper continuous profile, be it Bionda or not.
De acuerdo con la invención, el soporte comprende: According to the invention, the support comprises:
-un apeamiento de piezas que comprende una pieza de base fija inferior provista de medios para unión al suelo, una pieza cumbrera fija para acoplamiento de un perfil de cierre y, al menos, una pieza desglosadle intermedia, para desmembrarse en caso de impacto directo contra la misma, y  -a part appeal comprising a lower fixed base part provided with means for joining to the ground, a fixed ridge piece for coupling a closing profile and, at least, an intermediate broken-down piece, to disintegrate in case of direct impact against the same, and
-unos pórticos transversales salientes de las piezas desglosadles y unos túneles longitudinales correspondientes practicados en las piezas adyacentes, los cuales tienen normalmente forma de carril cerrado por su parte delantera, pero en todo caso abierto hada detrás, y sección igual o mayor a la forma de los pórticos para que dichos pórticos puedan desplazarse a io largo de los túneles correspondientes hasta salir por su abertura trasera, para que las piezas desglosadles puedan desglosarse en caso de impacto frontal directo contra las mismas;  -One transverse porches of the broken down pieces and corresponding longitudinal tunnels practiced in the adjacent pieces, which normally have the shape of a closed lane at the front, but in any case open behind, and section equal to or greater than the shape of the porches so that said porches can move along the corresponding tunnels until they exit through their rear opening, so that the broken down parts can be broken down in case of direct frontal impact against them;
-donde los pórticos se encuentran dispuestos en la parte anterior de la pieza desglosadle correspondiente, y  -where the porches are arranged in the front part of the corresponding item, and
-comprendiendo los túneles una garra extrema anterior provista de una rama sensiblemente horizontal dirigida hacia atrás e insertada en el pórtico correspondiente en posición de reposo para que en caso de impacto contra la pieza cumbrera se mantenga la integridad del apllamiento mediante la restricción del movimiento y del vuelco hacia detrás de las piezas del apilamiento por la acción de las garras contra los travesaños de los pórticos, mientras que en caso de impacto directo contra las piezas desglosadles intermedias las garras no actúan y nada impide que los pórticos salgan por la abertura trasera de los túneles permitiendo el desglose de dichas piezas desglosadles con una pequeña absorción de energía que impide daños contra el cuerpo que impacta contra el soporte.  -including the tunnels an anterior extreme claw provided with a substantially horizontal branch directed backwards and inserted in the corresponding gantry in rest position so that in case of impact against the ridge piece the integrity of the flattening is maintained by restricting the movement and the I turn back the stacking pieces by the action of the claws against the crossbars of the porches, while in case of direct impact against the intermediate broken pieces the claws do not act and nothing prevents the frames from leaving the rear opening of the tunnels allowing the breakdown of these pieces broken down with a small absorption of energy that prevents damage against the body that hits the support.
De esta forma, en caso de impacto contra el perfil bionda, que será el caso de un accidente de un vehículo, las fuerzas se transmiten de arriba hacia abajo y de adelante hada atrás a lo largo del soporte, impidiendo las garras su vuelco hacia atrás y el deslizamiento de las piezas superiores del apllamiento respecto de las inferieres, cumpliendo su cometido de sujetar el perfil bionda: mientras que en caso de impacto directo de un motorista que va deslizando a ras de suelo, las fuerzas no se transmiten de arriba hacia abajo por las piezas desglosadles, no actuando en este caso las garras y además deslizando cada pórtico de cada pieza desglosadle hasta salir por la parte trasera abierta de cada túnel, desmembrándose el soporte y minimizando los daños contra el cuerpo del motorista. BREVE DESCRIPCION DE LOS DIBUJOS In this way, in case of impact against the bionda profile, which will be the case of a vehicle accident, the forces are transmitted from top to bottom and from the front to the rear along the support, preventing the claws from tipping backwards. and the sliding of the upper parts of the flattening with respect to the lower ones, fulfilling its task of holding the biond profile: while in the case of a direct impact of a motorist who is sliding at ground level, the forces are not transmitted from top to bottom by the pieces broken down, the claws not acting in this case and also sliding each gantry of each piece broken down until leaving through the open back of each tunnel, dismantling the support and minimizing damage against the body of the motorist.

DESCRIPCION DE UNA REALIZACION PRACTICA DE LA INVENCION DESCRIPTION OF A PRACTICAL EMBODIMENT OF THE INVENTION
El soporte (1 ) para protecciones quitamiedos de carreteras de la invención comprende (ver fig 1 y 2): The support (1) for road guard protections of the invention comprises (see figs. 1 and 2):
-un apilamiento (6) de piezas que comprende una pieza de base (2) fija inferior provista de medios para unión al suelo (3), una pieza cumbrera (4) fija para acoplamiento de un perfil de aere (5) y. al menos, una pieza desglosadle (7, 7a) intermedia, para desmembrarse en caso de impacto directo contra la misma, y (ver también fig 6)  -a stacking (6) of pieces comprising a lower fixed base part (2) provided with means for ground connection (3), a fixed ridge piece (4) for coupling an air profile (5) and. at least one piece broken down (7, 7a) intermediate, to break up in case of direct impact against it, and (see also fig 6)
-unos pórticos (9) transversales salientes de las piezas desglosadles (7, 7a) y unos túneles (90) longitudinales correspondientes practicados en las piezas adyacentes, los cuides tienen forma de carril cerrado por su parte delantera y abierta hacia detrás y sección iguai o mayor a la forma de los pórticos (9) para que dichos pórticos (9) puedan desplazarse a lo largo de los túneles (90) correspondientes hasta salir por su abertura trasera (92) para que las piezas desglosables (7, 7a) puedan desglosarse en caso de impacto frontal directo contra las mismas, como se ve en las figs 4 y 5; -One transverse porches (9) protruding from the broken down pieces (7, 7a) and corresponding longitudinal tunnels (90) practiced in the adjacent pieces, the cuides are shaped lane closed at the front and open to the rear and section equal to or greater than the shape of the porches (9) so that said porches (9) can move along the corresponding tunnels (90) until they exit through their rear opening (92) so that the breakdown pieces (7, 7a) can be broken down in case of direct frontal impact against them, as seen in Figs. 4 and 5;
-donde los pórticos (9) se encuentran dispuestos en la parte anterior de la pieza desglosable (7, 7a) correspondiente, y  -where the frames (9) are arranged in the front part of the corresponding breakdown piece (7, 7a), and
-comprendiendo los túneles (90) una garra (93) extrema anterior (ver detalles de figs 2 y 3) provista de una rama sensiblemente horizontal (94) dirigida hacia atrás e insertada en el pórtico (9) correspondiente en posición de reposo para que en caso de impacto contra la pieza cumbrera (4) se mantenga la integridad del apilamiento (6) mediante ¡a restricción del movimiento y del vuelco hada detrás de las piezas (2, 4, 7, 7a) del apilamiento por ¡a acción de las garras (93) contra los travesaños (96) de los pórticos (9), como se ve en la fig 3, mientras que en caso de impacto directo contra las piezas desglosables (7, 7a) intermedias las garras (93) no actúan y nada impide que los pórticos (9) salgan por la abertura trasera (92) de los túneles (90) permitiendo e¡ desglose de dichas piezas desglosables (7, 7a) con una pequefia absorción de energía que impide daños contra el cuerpo que impacta contra el soporte (1 ).  - the tunnels (90) comprising an anterior end claw (93) (see details of figs 2 and 3) provided with a substantially horizontal branch (94) directed backwards and inserted into the corresponding gantry (9) in rest position so that in case of impact against the ridge piece (4) the integrity of the stack (6) is maintained by restricting the movement and overturning behind the pieces (2, 4, 7, 7a) of the stack by the action of the claws (93) against the crossbars (96) of the porches (9), as seen in fig 3, while in case of direct impact against the breakable parts (7, 7a) intermediate the claws (93) do not act and nothing prevents the porches (9) from leaving the rear opening (92) of the tunnels (90) allowing the breakdown of said breakdown parts (7, 7a) with a small energy absorption that prevents damage against the impacting body against the support (1).
En una primera variante de la invendón, no representada, el apilamiento (6) comprendería una única primera pieza desglosable (7) que comprendería sendos pórticos (9) superior e inferior para insertarse en un túnel (90) superior de la pieza de base (2) y de otro túnel (90) inferior de la pieza cumbrera (4). In a first variant of the invention, not shown, the stack (6) would comprise a single first breakdown piece (7) that would comprise both upper and lower portico frames (9) to be inserted into an upper tunnel (90) of the base piece ( 2) and another lower tunnel (90) of the ridge piece (4).
En otra posible realización déla invendón. que es la que se muestra en las figuras, el apilamiento (6) comprende una primera pieza desglosable (7) inferior y una o más segundas piezas desglosables (7a) dispuestas sucesivamente por endma y que comprenden cada una de ellas un pórtico (9) superior y un túnel (90) inferior, comprendiendo la pieza de base (2) un túnel (90) superior para paso del pórtico (9) inferior de la primera pieza desglosable (7). Concretamente en las figuras se muestra una variante con una primera pieza desglosable (7) inferior con sus pórticos (9) superior e inferior, y otra segunda pieza desglosable (7a) superior con un solo pórtico (9) superior In another possible embodiment of the invendon. which is the one shown in the figures, the stack (6) comprises a first lower breakable piece (7) and one or more second breakable pieces (7a) arranged successively by endma and each comprising a porch (9) upper and a lower tunnel (90), the base part (2) comprising an upper tunnel (90) for passage of the lower portico (9) of the first breakable part (7). Specifically in the figures, a variant is shown with a first lower breakable piece (7) with its upper and lower porches (9), and another second upper broken piece (7a) with a single upper gantry (9)
De forma muy preferente las garras (93) tienen forma de anzuelo., siendo la altura de su rama retenedora extrema (97) en la posición de reposo tal que no alcanza el travesano (96) del pórtico (9) correspondiente, como se ve en los detalles de la fig 2, para no impedir que en caso de impacto contra ia zona del soporte (1 ) ocupada por las piezas desglosares (7, 7a) esta rama retenedora extrema (97) pueda interferir con el deslizamiento hacia atrás de dicho travesaño (96). lo que se traducirla en una mayor resistencia contra el desglose, pero que en caso de impacto contra la bionda. la elevación anterior de las piezas (2, 4, 7, 7a) por el momento de vuelco precisamente enclave la rama retenedora extrema (97) contra el travesaño (96) y coopere en retener las piezas entre si impidiendo su deslizamiento. Preferably, the claws (93) are shaped like a hook, the height of its extreme retaining branch (97) being in the resting position such that it does not reach the crossbar (96) of the corresponding gantry (9), as seen in the details of fig 2, so as not to prevent in case of impact against the area of the support (1) occupied by the breakdown parts (7, 7a) this extreme retaining branch (97) may interfere with the sliding backward of said crossbar (96). which would result in a greater resistance against the breakdown, but that in case of impact against the bionda. the previous elevation of the pieces (2, 4, 7, 7a) by the moment of overturning precisely locks the extreme retaining branch (97) against the crossbar (96) and cooperates in retaining the pieces together preventing their sliding.
También se ha previsto que la pieza cumbrera (4) pueda comprender unas uñas (8) salientes interiormente en su zona trasera y dirigidas hacia atrás (ver figs 3 y 6); comprendiendo la pieza desglosadle (7, 7a) dispuesta superiormente unos topes (99) para apoyo de dichas uñas (8), para generar un momento de vuelco de la parte anterior de la pieza cumbrera (4) en caso de transmisión directa de fuerzas contra la misma y favorecer la transmisión vertical anterior de las fúerzas a través de las garras (93) y pórticos (9) con la finalidad de mantener la estabilidad formal del soporte (1 ) en caso de impacto contra la bionda. En este ejemplo puede verse como parte de las uñas (8) está desarrollada por encima del plano de apoyo contra la pieza inferior, pero en el momento del impacto el vuelco de la pieza cumbrera (4) hace que dichas uñas (8) entren completamente en los topes (99) como se ve en la fig 3. También se ha previsto que las uñas (8) puedan comprender unos planos inclinados (80) resbalones en su cara anterior, para favorecer el desmembramiento de las piezas desglosables (7, 7a) en el sentido adecuado de adelante hada atrás (ver detalle de fig 3). It is also provided that the ridge piece (4) can comprise nails (8) protruding internally in its rear area and directed backwards (see Figures 3 and 6); the piece comprising the breakdown (7, 7a) provided upper stops (99) for support of said nails (8), to generate a tipping moment of the front part of the ridge piece (4) in case of direct transmission of forces against the same and to favor the previous vertical transmission of the forces through the claws (93) and porches (9) in order to maintain the formal stability of the support (1) in case of impact against the bionda. In this example it can be seen how part of the nails (8) is developed above the support plane against the lower part, but at the moment of impact the overturning of the ridge piece (4) causes said nails (8) to enter completely in the stops (99) as seen in fig 3. It is also provided that the nails (8) can comprise inclined planes (80) slips on their front face, to favor the dismemberment of the breakable pieces (7, 7a ) in the right direction from front to back (see detail in fig 3).
Además, se ha previsto que la pieza de base (2) comprenda muy preferentemente una rampa (20) anterior que se encuentra proyectada por delante del apilamiento (6) para dirigir ai motorista contra las piezas desglosables (7, 7a) dispuestas inmediatamente sobre ella. Esta característica no sería necesaria si la pieza base (2) no sobresale del terreno. In addition, it is provided that the base part (2) very preferably comprises an anterior ramp (20) that is projected in front of the stack (6) to direct the motorist against the breakable parts (7, 7a) arranged immediately on it . This feature would not be necessary if the base piece (2) does not protrude from the ground.
En cuanto a los medios para unión al suelo de la pieza de base (2) comprenden por ejemplo unas garrotas (21 ) salientes inferiores (ver fig 1 ) o una placa de anclaje As regards the ground connection means of the base piece (2), for example, they comprise lower projections (21) (see fig. 1) or an anchor plate
Indicar que idealmente una o más de las piezas (2, 4, 7, 7a) se encuentran materializadas en plástico, y serán preferentemente huecas. Indicate that ideally one or more of the pieces (2, 4, 7, 7a) are materialized in plastic, and will preferably be hollow.
Descrita suficientemente la naturaleza de la invención, asi como la manera de realizarse en la práctica, debe hacerse constar que las disposiciones anteriormente indicadas y representadas en los dibujos adjuntos son susceptibles de modificaciones de detalle en cuanto no alteren el principio fundamental. Sufficiently described the nature of the invention, as well as the manner in which it is carried out in practice, it should be noted that the provisions indicated above and represented in the attached drawings are subject to modifications in detail in as long as they do not alter the fundamental principle.
