1. Resumen de la norma EN 1317<\/strong><\/strong><\/h3>\n\n\n\n

La norma EN 1317 es la norma europea unificada de certificaci\u00f3n de sistemas de contenci\u00f3n vial, que eval\u00faa el nivel de contenci\u00f3n, la anchura \u00fatil y el riesgo de lesiones por impacto. Todas las barreras de seguridad exportadas a la UE, Europa del Este y Oriente Medio deben superar ensayos de choque a escala real para obtener la certificaci\u00f3n de conformidad. La norma clasifica la protecci\u00f3n en los grados T, N, H y L; las barreras de viga en W y de tres vigas difieren considerablemente en su capacidad de carga debido a sus distintas estructuras de secci\u00f3n transversal.<\/p>\n\n\n\n

2. Comparaci\u00f3n de par\u00e1metros estructurales y de colisi\u00f3n<\/strong><\/strong><\/h3>\n\n\n\n

Barandilla de seguridad tipo W-Beam<\/strong><\/p>\n\n\n\n

Dimensiones: 310 mm de anchura, 2,5-3,0 mm de espesor, calidades certificadas T1-T3\/N1-N2. Soporta el peso de turismos de 1,5 t a velocidades de entre 80 y 110 km\/h gracias a su ondulaci\u00f3n flexible, que absorbe la energ\u00eda. Su baja rigidez provoca una fuerte deformaci\u00f3n ante el impacto de un cami\u00f3n, con una altura de instalaci\u00f3n est\u00e1ndar de entre 730 y 760 mm.<\/p>\n\n\n\n

Barandilla de tres vigas<\/strong><\/p>\n\n\n\n

Dimensiones: 506 mm de ancho, 3,0-4,0 mm de grosor, homologado para los grados de alta contenci\u00f3n N2\/H1-H3. Supera las pruebas de impacto con camiones de 10 t a 110 km\/h. El dise\u00f1o de triple onda aumenta la rigidez, dispersa la fuerza del impacto y evita que los veh\u00edculos salten la barrera, adapt\u00e1ndose a una instalaci\u00f3n de una o dos capas de 1 400 mm para cubrir toda la altura del veh\u00edculo.<\/p>\n\n\n\n

3. Principales diferencias en el comportamiento ante colisiones<\/strong><\/strong><\/h3>\n\n\n\n

1. Contenci\u00f3n:<\/strong> La viga en W solo es apta para turismos peque\u00f1os; la viga de tres vigas cumple con las normas obligatorias de clase H para las medianas de las autopistas y los tramos de puentes europeos.<\/p>\n\n\n\n

2. Necesidades de espacio:<\/strong> La viga en W requiere un espacio libre mayor junto a la carretera; la viga compacta de tres vigas se adapta a arcenes y tableros de puente estrechos.<\/p>\n\n\n\n

3. Seguridad y mantenimiento:<\/strong> El perfil de tres vigas reduce el riesgo de vuelco de los veh\u00edculos pesados en un 42% y mantiene la integridad estructural tras una colisi\u00f3n, lo que reduce considerablemente los costes de sustituci\u00f3n tras un accidente.<\/p>\n\n\n\n

4. Programa de emparejamiento de proyectos en el extranjero<\/strong><\/strong><\/h3>\n\n\n\n

\u2022 Viga en W: <\/strong>Carreteras rurales de baja velocidad, proyectos de categor\u00eda N de bajo presupuesto en los que el tr\u00e1fico est\u00e1 compuesto principalmente por turismos.<\/p>\n\n\n\n

\u2022 Thrie-Beam: <\/strong>Autov\u00edas de la UE, pendientes pronunciadas, rampas de salida y licitaciones de infraestructuras de alta seguridad de categor\u00eda H con tr\u00e1fico frecuente de camiones pesados.<\/p>\n\n\n\n

5. Consejos sobre exportaci\u00f3n y certificaci\u00f3n<\/strong><\/strong><\/h3>\n\n\n\n

1. Selecciona el tipo de viga en funci\u00f3n del grado de contenci\u00f3n de la licitaci\u00f3n.<\/p>\n\n\n\n

2. El acero de alta resistencia S355JR ofrece una mayor resistencia al impacto que el Q235B, lo que permite superar las pruebas de choque.<\/p>\n\n\n\n

3. La capa de zinc del galvanizado en caliente, de \u226585 \u03bcm, cumple con las normas europeas de protecci\u00f3n contra la corrosi\u00f3n en exteriores.<\/p>\n\n\n\n

4. Elaborar informes de pruebas de choque y certificados MTC y EN 1317 para la inspecci\u00f3n aduanera.<\/p>\n\n\n\n

Conclusi\u00f3n<\/strong><\/strong><\/h3>\n\n\n\n

Las barreras de tipo \u00abW-beam\u00bb ofrecen ventajas econ\u00f3micas para carreteras con poco tr\u00e1fico y bajo nivel de protecci\u00f3n, mientras que las de tipo \u00abthrie-beam\u00bb proporcionan una resistencia superior a los impactos en v\u00edas de alta velocidad con tr\u00e1fico de veh\u00edculos pesados. Los compradores deben elegir los productos en funci\u00f3n de los niveles de seguridad exigidos en la licitaci\u00f3n, los tipos de veh\u00edculos y el espacio disponible en los m\u00e1rgenes de la carretera, con el fin de encontrar un equilibrio entre la seguridad y los costes de adquisici\u00f3n.<\/p>","protected":false},"excerpt":{"rendered":"
