Abstract

Anclaje roscado para integrarse en el hormigón en un durmiente de ferrocarril o vía fija de traslado y la conexión positiva con un tornillo de durmiente que incluye una sección roscada (14) teniendo dispuestos en la parte externa del anclaje roscado pasos de rosca exterior (18), así como pasos de rosca interior (19) en la parte interna de los anclajes roscados; y una sección superior (16) colocada en posición de instalación cerca de la abertura del anclaje (26) sin rosca exterior; caracterizada porque el anclaje roscado presenta dos componentes de diferentes materiales, a saber, un cuerpo base de material plástico y un aro cilíndrico (20) de un material de acero, dispuesto en forma positiva y/o forzada.Reivindicación 6: Anclaje roscado de acuerdo con una de las reivindicaciones anteriores, caracterizado porque el coeficiente de dilatación térmica lineal del material de acero del aro cilíndrico (20) es por lo menos 10 veces menor que aquel del material sintético del cuerpo base (22), al que rodea, que no excede el coeficiente de dilatación térmica lineal del material de acero del aro cilíndrico (20) a 3 × 10-5 l/K. Reivindicación 7: Anclaje roscado de acuerdo con una de las reivindicaciones anteriores, caracterizado porque el coeficiente de dilatación térmica lineal del material de acero del aro cilíndrico (20) corresponde aproximadamente al del hormigón y no supera a 3 × 10-5 l/K. Reivindicación 8: Anclaje roscado de acuerdo con 6 y 7, caracterizado porque el material de acero del aro cilíndrico (20) se destaca por un módulo de elasticidad tan grande, que el aro cilíndrico dispuesto en el anclaje no se dilate de manera significativa al calentarse dentro del rango de temperatura en la que se utiliza. El módulo de elasticidad preferentemente presenta un máximo de 150 GPa. Reivindicación 10: Anclaje roscado de acuerdo con una de las reivindicaciones anteriores, caracterizado porque el aro cilíndrico (20) está recubierto preferentemente con una fina capa de plástico (24), cuyo espesor es de entre 0,1 mm. y 1 mm..Threaded anchor to be integrated into the concrete in a railway sleeper or fixed transfer track and the positive connection with a sleeper screw that includes a threaded section (14) having external thread passages (18) arranged on the external part of the threaded anchor , as well as internal thread passages (19) in the internal part of the threaded anchors; and an upper section (16) placed in the installation position near the anchor opening (26) without external thread; characterized in that the threaded anchor has two components of different materials, namely a base body of plastic material and a cylindrical ring (20) of a steel material, arranged in a positive and / or forced manner. Claim 6: Threaded anchor according with one of the preceding claims, characterized in that the coefficient of linear thermal expansion of the steel material of the cylindrical ring (20) is at least 10 times less than that of the synthetic material of the base body (22), which surrounds, which does not exceeds the coefficient of linear thermal expansion of the steel material of the cylindrical ring (20) at 3 × 10-5 l / K. Claim 7: Threaded anchor according to one of the preceding claims, characterized in that the coefficient of linear thermal expansion of the steel material of the cylindrical ring (20) corresponds approximately to that of the concrete and does not exceed 3 × 10-5 l / K. Claim 8: Threaded anchor according to 6 and 7, characterized in that the steel material of the cylindrical ring (20) is characterized by a modulus of elasticity so large, that the cylindrical ring disposed in the anchor does not dilate significantly when heated within the temperature range in which it is used. The elastic modulus preferably has a maximum of 150 GPa. Claim 10: Threaded anchor according to one of the preceding claims, characterized in that the cylindrical ring (20) is preferably coated with a thin layer of plastic (24), the thickness of which is between 0.1 mm. and 1 mm ..
