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.AN APPARATUS FOR MANUFACTURING PILES OR BEAMS MADE OF PRE-STRESSED CONCRETE, IN PARTICULAR SLEEVES FOR RAILWAYS, INCLUDING A CASTING MOLD DIVISIBLE IN SEGMENTS, EACH ONE OF WHICH HAS A DIFFERENT DURING THE MACHINES. APPLY A PREVIOUS VOLTAGE TO THE WIRE RUNNING THROUGH THE SEGMENTS, AND, ONCE THE CONCRETE HAS BEEN SET, SUCH WIRES MAY BE CUT BETWEEN THE RESPECTIVE SEGMENTS WITH THE AID OF A CUTTING DEVICE DEPENDED BY A PRESSURIZED BEAM. THE MOLDING SEGMENTS. THE ADJACENT MOLDING SEGMENTS ARE CONNECTED BETWEEN AT LEAST ONE AREA OF TRANSITION OR OPEN PASSAGE OF TRAPEZOID PROFILE AND SURROUNDING CONTINUOUS TENSION WIRE; MOLD IS HELD TO HELP MEDIA SUPPORT INSERTS IN DIRECTION VERTICAL RODS AND SUPPORT vertically extending ARE PROVIDED IN EACH PASSAGE OPEN Intersegment, EXTENDING THESE RODS THROUGH THE BOTTOM OF THE MOLD AND ADAPTED TO BE MOVED IN THE DIRECTION VERTICAL AND SEPARATELY FROM THE MOLD ; SUCH IS THE PROVISION THAT AFTER THE CONCRETE FORGING, THE BEAMS CONNECTED BETWEEN THEY ARE SUPPORTED BY THE SUPPORT RODS AT THE TIME THE MOLD IS REMOVED BY MOVING IT DOWN.
