Abstract

PROCEDIMIENTO DE FABRICACION DE TRAVIESAS POLIVALENTES; CONSISTENTE EN LA UTILIZACION DE UNA ARMADURA DE CABLES PRETENSADOS, CONTROLANDO LA FUERZA DE PRETENSADO ENTRE LAS TRAVIESAS, AL TIEMPO QUE SE MANTIENEN EN POSICION ELEVADA MIENTRAS LOS MOLDES DESCIENDEN, CON LO QUE SE SUPRIMEN FUERZAS ASCENSIONALES Y SE MINIMIZAN LOS DESPLAZAMIENTOS DE LAS TRAVIESAS A LO LARGO DE LA BANCADA. UNAS PLACAS DE COMPRESION SITUADAS ENTRE LOS EXTREMOS DE CADA ELEMENTO CONTIGUO Y UNOS ORGANOS DE COMPRESION QUE SE APLICAN SOBRE ESTAS PLACAS MANTIENEN LAS TRAVIESAS EN POSICION SIN APLICAR FUERZA ASCENSIONAL ALGUNA. LA ARMADURA ESTA CONSTITUIDA POR CABLES PRETENSADOS DE LOS QUE LOS CUATRO CORRESPONDIENTES A LA ZONA SUPERIOR SON DE MAYOR DIAMETRO QUE LOS OCHO DE LA INFERIOR.
