Abstract
UN APARATO PARA FABRICAR PILOTES O VIGAS HECHAS DE HORMIGON PRETENSADO, EN PARTICULAR DURMIENTES PARA VIAS FERREAS, COMPRENDIENDO UN MOLDE DE VACIADO DIVISIBLE EN SEGMENTOS, CADA UNO DE LOS CUALES TIENE EL LARGO DE UNA VIGA, PROVEYENDOSE EN LOS EXTREMOS DEL MOLDE DE VACIADO DISPOSITIVOS PARA APLICAR UNA TENSION PREVIA A LOS ALAMBRES QUE CORREN POR LOS SEGMENTOS, Y, UNA VEZ FRAGUADO EL HORMIGON, DICHOS ALAMBRES PUEDEN SER CORTADOS ENTRE LOS RESPECTIVOS SEGMENTOS CON AYUDA DE UN DISPOSITIVO CORTADOR, A FIN DE OBTENER VIGAS PRETENSADAS SEPARADAS Y DE UN LARGO DETERMINADO POR LOS SEGMENTOS DE MOLDE. LOS SEGMENTOS DE MOLDE ADYACENTES ESTAN CONECTADOS ENTRE SI POR AL MENOS UN AREA DE TRANSICION O PASAJE ABIERTO DE PERFIL TRAPEZOIDAL Y QUE RODEA LOS ALAMBRES TENSORES CONTINUOS; EL MOLDE ESTA SOSTENIDO CON AYUDA DE MEDIOS DE SOPORTE MOVIBLES EN DIRECCION VERTICAL Y VARILLAS DE SOPORTE EXTENDIDAS VERTICALMENTE SE PROVEEN EN CADA PASAJE ABIERTO ENTRE SEGMENTOS, EXTENDIENDOSE DICHAS VARILLAS A TRAVES DEL FONDO DEL MOLDE Y ADAPTADAS PARA SER MOVIDAS EN DIRECCION VERTICAL Y SEPARADAMENTE DEL MOLDE; SIENDO TAL LA DISPOSICION QUE LUEGO DEL FRAGUADO DEL HORMIGON, LASVIGAS CONECTADAS ENTRE SI QUEDAN SOSTENIDAS POR LAS VARILLAS DE SOPORTE EN EL MOMENTO EN QUE EL MOLDE ES DESPRENDIDO DESPLAZANDOLO HACIA ABAJO.
