2 Se definen como dispositivos que enlazan los bordes de dos tableros contiguos o de un tablero y un estribo, de forma que permiten movimientos relativos entre los mismos manteniendo una superficie lo más continua posible. Are defined as devices that links the edges of two adjacent bridge decks, or a bridge edge with the end of the bridge; so that, allow movements maintaining a flat and even surface. Las condiciones que deben cumplir estos tipos de juntas son: The conditions required for these expansion joints are: Elasticidad, para acompañar los movimientos sin agrietarse o transmitir esfuerzos inadmisibles en los tableros. Elasticity, to move without cracking or transmitting unacceptable stresses to the bridge decks. Impermeabilidad, evitando cualquier filtración y proporcionando un sellado adecuado. Waterproofing, preventing leaks and providing a proper seal. Resistencia, para soportar sin roturas ni excesivo desgaste los efectos de impacto y abrasión debidos al tráfico. Resistance, to bear without crack or excessive wear the effect of impact and abrasion due to traffic. Se componen de una estructura de acero recubierta con caucho vulcanizado que permite la absorción de los movimientos de contracción y dilatación de los tableros de puente. They consist of a steel structure covered with vulcanized rubber, allowing the absorption of contraction and expansion movement of the bridge decks. Los módulos se fijan con pernos de anclaje a los bordes de la estructura mediante resinas epoxi y son reforzados con arandelas y tuercas autoblocantes. The module edges are fixed with bolts using epoxy resins, and are reinforced with washers and locking nuts. El diseño de cada tipo de junta ha sido realizado para soportar largos ciclos de carga (compresión dilatación) así como para la absorción de los esfuerzos, disminuyendo de esta manera su transmisión a los sistemas de anclaje. Each Joint has been designed to withstand long loading cycles (compression-expansion), as well as to support the absorption of effort, reducing force transmission to anchor system.
