Abstract

UN APARATO PARA PRODUCCION DE BLOQUES O TRAVIESAS DE HORMIGON PRETENSADO, EN PARTICULAR TRAVIESAS DE FERROCARRIL. EL APARATO COMPRENDE UN MOLDE DE FRAGUADO QUE SE DIVIDE EN SEGMENTOS CADA UNO CON LA LONGITUD DEL BLOQUE QUE SE PRODUCIRA. SE DISPONEN DISPOSITIVOS TENSADORES DE CABLE EN LOS EXTREMOS DEL MOLDE DE FRAGUADO PARA TENSAR LOS CABLES RETENSANTES QUE CORREN POR LOS SEGMENTOS. TRAS EL ENDURECIMIENTO DEL HORMIGON VOLCADO EN EL MOLDE DE FRAGUADO, ESTOS CABLES PRETENSANTES PUEDEN CORTARSE ENTRE LOS SEGMENTOS RESPECTIVOS POR MEDIO DE UN DISPOSITIVO DE CORTE DE UNA LONGITUD DETERMINADA POR LOS SEGMENTOS DEL MOLDE. DE ACUERDO CON EL INVENTO, SE INTERCONECTAN SEGMENTOS DE MOLDE ADYACENTES POR AL MENOS UN PASO ABIERTO (3) DE SECCION TRANSVERSAL TRAPEZOIDAL QUE RODEA LOS CABLES PRETENSANTES CONTINUOS (6), EL MOLDE (16) ESTA SUJETADO POR SISTEMAS DE SUJECION (13) QUE PUEDE MOVERSE EN DIRECCION VERTICAL Y SE DISPONEN VARILLAS DE SUJECION DIRIGIDAS VERTICALMENTE (34) EN CADA PASO ABIERTO (3) ENTRESEGMENTOS DE MOLDE ADYACENTES. ESTAS VARILLAS DE SUJECION (34) SE EXTIENDEN POR LA PARTE INFERIOR DEL MOLDE (16) Y PUEDEN MOVERSE EN DIRECCION VERTICAL SEPARADAMENTE DEL MOLDE (16). LA ESTRUCTURA ES TAL QUE TRAS EL ENDURECIMIENTO DEL HORMIGON VOLCADO AL MOLDE (16), LOS BLOQUES INTERCONECTADOS (1,1'') PERMANECEN SUJETOS POR LAS VARILLAS DE SUJECION (34) DURANTE LA LIBERACION DEL MOLDE POR UN DESPLAZAMIENTO EN SENTIDO DESCENDENTE DEL MOLDE (16).
