Abstract

TENDON (100, 200) PARA UNA ESTRUCTURA DE HORMIGON PREFATIGADO QUE INCLUYE UN MIEMBRO NUCLEAR (1), COMO, POR EJEMPLO, UNA ALAMBRE DE ACERO, UN TORON DE ACERO O UNA BARRA DE ACERO; Y UN MATERIAL DE CONEXION SIN FIJAR (2) QUE RECUBRE LA ESTRUCTURA DEL NUCLEO PARA UN DETERMINADO GROSOR, QUE TIENE UN TIEMPO DE MONTAJE ESPECIFICO DETERMINADO SELECTIVAMENTE LOS RESPECTIVOS CONTENIDOS DEL MATERIAL DE CONEXION Y QUE SE FIJA A TEMPERATURA ORDINARIA MEDIANTE UNA REACCION QUIMICA; Y UNA CUBIERTA ONDULADA SIN COSTURA (4) DE GRAN ENVERGADURA. EL TENDON (100,200) SE FABRICA CONTINUAMENTE RECUBRIENDO UN MIEMBRO NUCLEAR DE UN TORON DE ALAMBRE (1) CON UN ADHESIVO DE CONEXION SIN FIJAR (2), EXTRUYENDO MEDIANTE FUSION Y CONTRAYENDO UNA CUBIERTA PLASTICA SIN COSTURA (4) ALREDEDOR DEL MIEMBRO NUCLEAR RECUBIERTO, DEFORMANDO LA CUBIERTA DE PLASTICO (4) HASTA UNA FORMA ONDULADA SIENDO MAS PROFUNDO EL CALADO DE UNA PORCION DENTADA QUE EL GROSOR DEL PLASTICO QUE FORMA LA CUBIERTA Y ENFRIANDO EL TENDON. EL TENDON (100, 200) DE GRAN ENVERGADURA SE DEVANA EN EL CARRETE PARA SU ALMACENAMIENTO, SE AJUSTA DESDE EL CARRETE Y SE CORTA A LA LONGITUD PREDETERMINADA, Y SE FIJAN LOS ANCLAJES AL EXTREMO DE CADA CARRETE. SE DISPONE EL TENDON EN LA DISPOSICION DESEADA PARA FORMAR UNA ESTRUCTURA DE HORMIGON PREFATIGADA, SE COLOCA EL HORMIGON DE FORMA QUE SEPULTE LOS TENDONES, Y LUEGO SE TENSAN Y FIJAN LOS TENDONES DESPUES QUE LA FUERZA DEL HORMIGON DEPOSITADO HA AUMENTADO A UN GRADO TAL QUE PERMITE TENSAR LOS TENDONES Y ANTES DE QUE SE FIJE EL MATERIAL DE CONEXION SIN FIJAR. ASI, EL MATERIAL DE CONEXION SIN FIJAR (2) SE FIJA DESPUES QUE SE HAN TENSADO LOS TENDONES (100, 200) Y UNE FIRMEMENTE LOS TENDONES A LA ESTRUCTURA DE HORMIGON PREFATIGADO.
