Abstract

ELEMENTO DE CONSTRUCCION ESPUMADO Y DISPOSITIVO Y PROCEDIMIENTO PARA FABRICAR EL MISMO. PARA FABRICAR ELEMENTOS DE CONSTRUCCION ESPUMADOS SE INTRODUCE EN UN MOLDE DE COLADA POR INYECCION UNA TIRA A BASE DE UNA MARAÑA COHERENTE DE HILOS QUE MANTIENE A UNAS ESTERILLAS DE REFUERZO EN SU SITIO Y A LA DISTANCIA REQUERIDA. LAS ESTERILLAS DE REFUERZO SE POSICIONAN ASI EN LA ZONA DEL FORRO EXTERIOR DEL PRODUCTO TERMINADO, SIN QUE SEAN ARRASTRADAS POR EL CHORRO DE INYECCION HACIA NINGUNA ZONA DE BORDE DE MOLDE. SE OBTIENEN DE ESTE MODO ELEMENTOS DE CONSTRUCCION MUY LIGEROS Y CAPACES DE SOMETERSE A GRANDES CARGAS, LOS CUALES PUEDEN UTILIZARSE ALLI DONDE IMPORTE TANTO UN PESO REDUCIDO COMO TAMBIEN UNA ALTA RIGIDEZ Y UNA FABRICACION BARATA.
