Dispositivo de apoyo de puentes y viaductos Bridge and viaduct support device

OBJETO DE LA INVENCIÓN OBJECT OF THE INVENTION

La presente solicitud tiene por objeto el registro de un dispositivo de apoyo de puentes y viaductos. The purpose of this application is to register a support device for bridges and viaducts.

Más concretamente, la invención propone el desarrollo de un dispositivo de apoyo previsto en la construcción de puentes y viaductos para amortiguar o transmitir las fuerzas que tienen lugar en la estructura por condiciones del terreno, climatológicas, ambientales, etc. More specifically, the invention proposes the development of a support device provided in the construction of bridges and viaducts to dampen or transmit the forces that take place in the structure due to terrain, weather, environmental conditions, etc.

ANTECEDENTES DE LA INVENCIÓN BACKGROUND OF THE INVENTION

Los puentes y viaductos están construidos en general a base de un conjunto de pilares verticales que descansan sobre sus cimientos, colocándose sobre dichos pilares unos dinteles que soportan un conjunto de vigas dispuestas longitudinalmente, las cuales sirven de apoyo a los tableros que constituyen la plataforma sobre la que se construye una calzada por la que circulan vehículos, personas, etc. The bridges and viaducts are built in general based on a set of vertical pillars that rest on their foundations, with lintels that support a set of longitudinally arranged beams, which support the boards that constitute the platform on the platform the one that builds a road through which vehicles, people, etc. circulate.

Los tableros no pueden disponerse a tope porque se requieren holguras donde deben instalarse unas juntas de dilatación que permitan absorber los movimientos que se produzcan por las variaciones de temperatura, efectos de frenado y retracción del hormigón. The boards cannot be fully butted because clearances are required where expansion joints must be installed to absorb the movements that occur due to temperature variations, braking effects and concrete retraction.

Por ello, es necesario, que las vigas descansen sobre unos apoyos elásticos que permitan que los tableros se muevan, abriéndose y cerrándose las juntas, sin causar ningún daño estructural. De este modo, estos apoyos transmiten las fuerzas tanto gravitatorias como vivas a los pilares, liberando los movimientos y rotaciones de los tableros de los puentes con respectos a los pilares. Therefore, it is necessary that the beams rest on elastic supports that allow the boards to move, opening and closing the joints, without causing any structural damage. In this way, these supports transmit both gravitational and living forces to the pillars, releasing the movements and rotations of the bridge boards with respect to the pillars.

Un ejemplo de apoyos elásticos conocidos es aquellos que están constituidos por una cazoleta que presenta un rebaje central en cuyo interior está alojada una almohadilla discoidal hecha de un material elástico (tal como, por ejemplo, cloropreno o caucho natural) que tiene un comportamiento a presión muy bueno, comportándose tal material como un Para mantener en su sitio la almohadilla y evitar que el material fluya por fuera del pistón cuando se aplica presión sobre la almohadilla, se disponen de unos medios de estanqueidad que están comprendidos por dos aros de latón, superpuestos uno encima del otro, albergados en una hendidura dispuesta en la almohadilla discoidal. Si bien este sistema de estanqueidad tiene un buen funcionamiento, implica un sobredimensionado del conjunto, por lo que se requiere mayor material a utilizar para las diversas partes que conforman el conjunto y, por consiguiente, un mayor coste del mismo. An example of known elastic supports is those that are constituted by a bowl that has a central recess in which a discoidal pad made of an elastic material (such as, for example, chloroprene or natural rubber) is housed, which has a pressure behavior very good, such material behaving as a To keep the pad in place and prevent the material from flowing out of the piston when pressure is applied on the pad, there are a means of sealing that are comprised of two brass rings, superimposed one on top of the other, housed in a slit arranged in the discoid pad. Although this sealing system has a good functioning, it implies an oversizing of the assembly, so that more material is required to be used for the various parts that make up the assembly and, consequently, a greater cost thereof.

5 en lo que se refiere al material elástico y unas dimensiones globales del dispositivo menores respecto a los dispositivos de la técnica conocida, que, en una condición funcional, es decir, cuando el elemento anular superior recibe una fuerza de compresión, producida esencialmente por la placa pistón, éste ejerce una fuerza de expansión sobre tal elemento anular superior, comprimiendo el elemento anular superior contra el contorno interior de la 5 as regards the elastic material and smaller overall dimensions of the device with respect to the devices of the known technique, which, in a functional condition, that is, when the upper annular element receives a compression force, produced essentially by the piston plate, this exerts an expansion force on such upper annular element, compressing the upper annular element against the inner contour of the

10 cazoleta, mejorando con ello la estanqueidad, evitando que el material elástico pueda “fluir” forma indeseada por la pared lateral del rebaje de la cazoleta hacia el exterior. 10 bowl, thereby improving the tightness, preventing the elastic material from "flowing" unwantedly through the side wall of the bowl recess outwards.

En una realización preferida, cabe la posibilidad de que cada uno de los dos elementos anulares está abierto tal que presenta una discontinuidad, estando cada una de las dos 15 discontinuidades dispuestas diametralmente opuestas entre sí, lo que garantiza un óptimo grado de estanqueidad por parte de los dos elementos anulares. In a preferred embodiment, it is possible that each of the two annular elements is open such that it has a discontinuity, each of the two discontinuities arranged diametrically opposed to each other, which guarantees an optimum degree of tightness on the part of The two ring elements.

Para evitar la entrada de polvo y otras partículas de suciedad al interior del rebaje donde está alojada la almohadilla, se proporcionan unos medios de estanqueidad secundarios que 20 están en contacto con la cara interior de la cazoleta y la placa pistón. To prevent the entry of dust and other dirt particles into the recess where the pad is housed, secondary sealing means are provided that are in contact with the inner face of the bowl and the piston plate.

Preferentemente, los medios de estanqueidad secundarios están alojados en una hendidura perimetral presente en la pared lateral de la placa pistón. Preferably, the secondary sealing means are housed in a perimeter groove present in the side wall of the piston plate.
