Description

CUBIERTA PARA ELEMENTOS DE BARRERA COVER FOR BARRIER ELEMENTS

OBJETO DE LA INVENCIÓN OBJECT OF THE INVENTION

La presente invención se puede incluir dentro del campo técnico de la construcción, en particular dentro de la construcción de carreteras. De manera más concreta la invención se refiere a una cubierta para elementos de barrera, en particular, en carreteras, pero válida igualmente para las de vías ferroviarias y aeropuertos, entre otros. The present invention can be included within the technical field of construction, particularly within road construction. More specifically, the invention relates to a cover for barrier elements, in particular on roads, but also valid for those of railway tracks and airports, among others.

ANTECEDENTES DE LA INVENCIÓN BACKGROUND OF THE INVENTION

Existen una serie de limitaciones, incomodidades o peligros asociados al transporte por carretera. Uno de ellos es el ruido emitido por los vehículos, que afecta gravemente a la calidad de vida de los usuarios de la carretera, de las personas que viven o trabajan en poblaciones cercanas a una carretera, y de la fauna cuyo hábitat se encuentra en el entorno de una carretera. There are a number of limitations, discomforts or dangers associated with road transport. One of them is the noise emitted by vehicles, which seriously affects the quality of life of road users, people who live or work in towns near a road, and wildlife whose habitat is found in the Road environment.

A menudo se disponen pantallas acústicas a los lados de las carreteras, para evitar la transmisión de ruido hacia el exterior. Sin embargo, dichas pantallas no evitan que el ruido rebote hacia la propia carretera y moleste a los conductores, puesto que la efectividad de las pantallas disminuye en función de la distancia a la fuente de ruido. Por otro lado, los elementos de barrera que separan las calzadas de un sentido y del sentido opuesto (o que delimitan el margen de la calzada) no son capaces de impedir la transmisión de ruido y sobre todo de luz desde la calzada de un sentido hacia la calzada del sentido contrario. En el caso de la luz, presenta un inconveniente doble: por un lado, el deslumbramiento de los conductores que circulan por la calzada opuesta y, por otro lado, el impacto sobre los biorritmos de la fauna. Acoustic screens are often arranged on the sides of the roads, to prevent the transmission of noise to the outside. However, these screens do not prevent noise from bouncing towards the road itself and disturbing drivers, since the effectiveness of the screens decreases depending on the distance to the noise source. On the other hand, the barrier elements that separate the roadways from one direction and the opposite direction (or that delimit the margin of the roadway) are not able to prevent the transmission of noise and especially light from the roadway of one direction towards the road in the opposite direction. In the case of light, it has a double drawback: on the one hand, the glare of the conductors that circulate on the opposite road and, on the other hand, the impact on wildlife biorhythms.

Adicionalmente, los elementos de barrera están adaptados para recibir el impacto de vehículos y evitar que dichos vehículos invadan el carril contrario, (o salgan despedidos fuera de la calzada) pero para ello deben ser pesados y estar fabricados en materiales duros, lo cual implica un gran peligro, esencialmente de muerte, en especial cuando el conductor de un vehículo de dos ruedas impacta contra dichos elementos de barrera. Additionally, the barrier elements are adapted to receive the impact of vehicles and prevent said vehicles from invading the opposite lane, (or being fired out of the road) but for this they must be heavy and made of hard materials, which implies a great danger, essentially of death, especially when the driver of a two-wheeled vehicle impacts against such barrier elements.

Por tanto, a la vista de lo anteriormente comentado, el problema técnico que se pretende resolver por medio de la invención es mejorar las prestaciones de la carretera de manera que se produzca una disminución del nivel de ruido, de luz y se mejore la seguridad de conductores de vehículos de dos ruedas. DESCRIPCIÓN DE LA INVENCIÓN Therefore, in view of the aforementioned, the technical problem that is intended to be solved by means of the invention is to improve the performance of the road so that there is a decrease in the level of noise, light and the safety of Two wheel vehicle drivers. DESCRIPTION OF THE INVENTION

La presente invención resuelve los problemas mencionados mediante una cubierta para elementos de barrera en carreteras. Dicha cubierta está planeada para cubrir al menos una porción longitudinal de un elemento de barrera, tales como las barreras de tipo New Jersey que se disponen para separar calzadas de carriles, o las biondas o los quitamiedos dispuestos para evitar salidas en curvas, o barreras ferroviarias, entre otras. The present invention solves the aforementioned problems by means of a cover for road barrier elements. Said cover is planned to cover at least a longitudinal portion of a barrier element, such as the New Jersey type barriers that are arranged to separate lanes of rails, or the biondas or the removers arranged to avoid bends in curves, or rail barriers. , among other.

La cubierta de la invención comprende un tramo inferior adaptado para disponerse a lo largo de al menos una porción en dirección longitudinal de un elemento de barrera, así como comprende un tramo superior dispuesto sobre el tramo inferior para sobresalir sobre la parte superior del elemento de barrera. De manera preferente, el tramo inferior cubre la porción del elemento de barrera. De este modo, el tramo se dispone a lo largo de un elemento de barrera, pudiendo superponerse o no, tanto para barreras New Jersey, como para quitamiedos, etc. El tramo inferior está fabricado con un primer material, absorbente de los impactos, adecuado para, por ejemplo, evitar lesiones graves a conductores de motos o bicicletas en caso de impacto a una velocidad superior a 50 km/h. Ejemplos de dichos materiales son los pertenecientes al tipo conocido como "gomas", tales como caucho y sus derivados, u otros materiales poliméricos de propiedades adecuadas, como por ejemplo, los conocidos como SBR (caucho- estireno-butadieno) o EPDM (monómero de etilén-propilén-dieno). Preferentemente, el primer material es adicionalmente un material absorbente acústico dentro del espectro acústico de la carretera, como es el caso de SBR y de EPDM. Alternativamente, el primer material y/o el segundo material pueden tener una configuración de cavidades interiores que aportan ligereza y mayor absorción mecánica. The cover of the invention comprises a lower section adapted to be arranged along at least a longitudinally directed portion of a barrier element, as well as comprising an upper section arranged on the lower section to project over the upper part of the barrier element . Preferably, the lower section covers the portion of the barrier element. In this way, the section is arranged along a barrier element, being able to overlap or not, both for New Jersey barriers, as for removers, etc. The lower section is made of a first material, shock absorbing, suitable for, for example, preventing serious injuries to motorcycle or bicycle drivers in case of impact at a speed exceeding 50 km / h. Examples of such materials are those belonging to the type known as "gums", such as rubber and its derivatives, or other polymeric materials of suitable properties, such as those known as SBR (rubber- styrene-butadiene) or EPDM (ethylene-propylene-diene monomer). Preferably, the first material is additionally an acoustic absorbent material within the acoustic spectrum of the road, such as SBR and EPDM. Alternatively, the first material and / or the second material may have a configuration of interior cavities that provide lightness and greater mechanical absorption.

El tramo superior está fabricado con un segundo material, no transparente, (preferentemente opaco) y absorbente acústico. El material SBR y el EPDM verifican también dichas características. Dicho tramo superior presenta de manera preferente una configuración adaptada para minimizar reflexiones de sonido hacia el exterior. Un ejemplo de dicha forma puede ser la disposición de salientes y entrantes de formas geométricas regulares o arbitrarias. The upper section is made of a second material, not transparent, (preferably opaque) and acoustic absorbent. The SBR material and the EPDM also verify these characteristics. Said upper section preferably has an adapted configuration to minimize outward sound reflections. An example of such a form may be the arrangement of projections and recesses of regular or arbitrary geometric shapes.

El tramo superior puede ser macizo, pero preferentemente es hueco o al menos contiene huecos en su interior, con lo cual se consigue reducir el peso del producto y el coste del material. La cubierta puede estar elaborada en una sola pieza, fabricada preferentemente por moldeo, sin embargo, alternativamente, el tramo superior y el tramo inferior constituyen piezas diferentes relacionadas por medio de unos medios de unión. Dichos medios de unión pueden ser, a modo de ejemplo ilustrativo y no limitativo, colas de milano, tetones, adhesivos, etc. Del mismo modo, con el fin de obtener una altura final adecuada a las circunstancias, tanto para el caso de dos piezas como para el caso de una sola, el tramo superior puede estar constituido por una pluralidad de elementos apilados unidos convenientemente, por ejemplo mediante colas de milano u otros medios adecuados. The upper section can be solid, but preferably it is hollow or at least it contains holes in its interior, which reduces the weight of the product and the cost of the material. The cover can be made in one piece, preferably manufactured by molding, however, alternatively, the upper section and the lower section constitute different related parts by means of joining means. Said joining means can be, by way of illustration and not limitation, dovetails, lugs, adhesives, etc. Similarly, in order to obtain a final height appropriate to the circumstances, both for the case of two pieces as for the case of only one, the upper section may be constituted by a plurality of stacked elements conveniently joined, for example by dovetails or other suitable means.

Según una opción preferente, el primer material y/o el segundo material pueden ser materiales reciclados. De esta manera se consigue un ahorro en costes, así como se reduce el impacto ambiental de la fabricación de la cubierta de la invención. According to a preferred option, the first material and / or the second material may be recycled materials. In this way, cost savings are achieved, as well as the environmental impact of the fabrication of the cover of the invention is reduced.

De manera preferente, la cubierta es reflectante, pudiendo incorporar, tanto en el tramo inferior como en el tramo superior o en ambos, unos elementos reflectantes, del estilo de catadióptricos. Alternativamente, la cubierta puede estar recubierta de una pintura reflectante. Alternativamente, el primer material y/o el segundo material, en caso de ser materiales moldeables, comprenden en su composición una proporción de pintura reflectante. Preferably, the cover is reflective, being able to incorporate, both in the lower section and in the upper section or in both, reflective elements, of the catadioptric style. Alternatively, the cover may be coated with a reflective paint. Alternatively, the first material and / or the second material, if they are moldable materials, comprise in their composition a proportion of reflective paint.

Mediante la cubierta de la invención se consigue, con una inversión muy reducida (sin necesidad de sustituir los elementos de barrera existentes), una protección de los motoristas y ciclistas f ente a impactos, así como se reduce el nivel de ruido de las carreteras y los deslumbramientos. Adicionalmente, se reduce el impacto sobre la fauna de las zonas aledañas a las carreteras. DESCRIPCIÓN DE LOS DIBUJOS By means of the cover of the invention, with a very small investment (without the need to replace the existing barrier elements), motorists and cyclists are protected from impacts, as well as the noise level of the roads and the glare Additionally, the impact on the fauna of the areas surrounding the roads is reduced.

REALIZACIÓN PREFERENTE DE LA INVENCIÓN Seguidamente se realiza, con ayuda de las figuras 1 a 4 adjuntas, una descripción detallada de cuatro realizaciones preferentes de la presente invención. Tal como se aprecia en la figura 1, se describe una cubierta (1) para elementos de barrera (4) en carreteras, que comprende un tramo inferior (2) y un tramo superior (3). El tramo inferior (2) está adaptado para ser dispuesto cubriendo un tramo longitudinal de una barrera (4) tipo New Jersey fabricada en hormigón. PREFERRED EMBODIMENT OF THE INVENTION Next, a detailed description of four preferred embodiments of the present invention is carried out with the help of the attached figures 1 to 4. As can be seen in Figure 1, a cover (1) for barrier elements (4) on roads is described, comprising a lower section (2) and an upper section (3). The lower section (2) is adapted to be arranged covering a longitudinal section of a New Jersey type barrier (4) made of concrete.

El tramo superior (3) constituye, en este caso, una pieza independiente del tramo inferior (2) y está dispuesto sobre dicho tramo inferior (2) para sobresalir sobre la parte superior de la barrera (4), de modo que el tramo superior (3) y el tramo inferior (2) están unidos separablemente por colas de milano (5). The upper section (3) constitutes, in this case, an independent part of the lower section (2) and is arranged on said lower section (2) to project over the upper part of the barrier (4), so that the upper section (3) and the lower section (2) are detachably joined by dovetails (5).

El tramo inferior (2) está fabricado con un primer material absorbente de impactos y absorbente acústico. El tramo superior (3) está fabricado con un segundo material opaco y esencialmente absorbedor acústico, hueco en su interior, así como presenta zonas exteriores con salientes (6) y entrantes (7) para minimizar reflexiones de sonido hacia el exterior. El primer material y el segundo material son SBR o EPDM, preferentemente reciclados de otros usos. Dichos materiales son materiales moldeables y comprenden una proporción de pintura reflectante, así como aditivos para dotar de carácter ignífugo a la cubierta (1). El tramo superior (3) y el tramo inferior (2) están unidos separablemente por colas de milano (5). En la figura 2 se muestra una segunda realización de la invención, donde el tramo superior (3) y el tramo inferior (2) de la cubierta (1) constituyen dos piezas distintas encajadas, así como el tramo inferior (2) no cubre el elemento de barrera (4), que en este caso es un quitamiedos. Asimismo, el tramo superior (3) es hueco. The lower section (2) is made of a first shock absorbing and acoustic absorbent material. The upper section (3) is made of a second opaque and essentially acoustic absorber material, hollow inside, as well as exterior areas with protrusions (6) and recesses (7) to minimize outward sound reflections. The first material and the second material are SBR or EPDM, preferably recycled from other uses. Said materials are moldable materials and comprise a proportion of reflective paint, as well as additives to provide the cover with a flame retardant character (1). The upper section (3) and the lower section (2) are detachably joined by dovetails (5). A second embodiment of the invention is shown in Figure 2, where the upper section (3) and the lower section (2) of the cover (1) constitute two different pieces fitted together, as the lower section (2) does not cover the Barrier element (4), which in this case is a quitamiedos. Also, the upper section (3) is hollow.

En la figura 3 se describe una tercera realización de la invención, donde la cubierta (1) es de una sola pieza, siendo el tramo superior (3) macizo, y estando el tramo inferior (2) adaptado para cubrir un elemento de barrera (no representado). A third embodiment of the invention is described in Figure 3, where the cover (1) is in one piece, the upper section (3) being solid, and the lower section (2) being adapted to cover a barrier element ( not represented).

En la figura 4 se aprecia una cuarta realización de la invención, donde la cubierta (1) es de una sola pieza, siendo el tramo superior (3) macizo y estando adaptado para ser dispuesto recubriendo el elemento de barrera (no representado) donde el tramo inferior (2) se dispone a ambos lados de dicho elemento de barrera. Figure 4 shows a fourth embodiment of the invention, where the cover (1) is in one piece, the upper section (3) being solid and adapted to be arranged by covering the barrier element (not shown) where the lower section (2) is disposed on both sides of said barrier element.
