Abstract

LA INVENCION SE REFIERE A UN ELEMENTO DE FUNDA (35) PREPARADO PARA EXTENDERSE A LO LARGO DE UNA PORCION (9) DE LA ESTRUCTURA PRETENSADA EN UNA PARTE ELEVADA DE UN TRAYECTO SINUOSO QUE SIGUE EL CABLE PRETENSOR. ESTE ELEMENTO COMPRENDE UN CANAL DE AIREACION (41) PARALELO A LA CAVIDAD TUBULAR (20) QUE RECIBE LOS TRENZADOS DE CABLE Y ES DE SECCION CLARAMENTE INFERIOR A LA CAVIDAD TUBULAR. ESTE CANAL DE AIREACION ESTA MONTADO DE MANERA QUE, DESPUES DE COLOCAR EL ELEMENTO DE FUNDA (35) EN LA MENCIONADA PORCION DE LA ESTRUCTURA, EL CANAL QUEDA POR ENCIMA DE LA CAVIDAD TUBULAR Y SE COMUNICA CON ESTA EN UNA ZONA DEL ELEMENTO DE FUNDA SITUADA EN EL INTERIOR DE DICHA PORCION DE LA ESTRUCTURA, Y CON EL EXTERIOR DE LA FUNDA EN UNA REGION DEL ELEMENTO DE FUNDA SITUADA POR FUERA DE LA MENCIONADA PORCION DE ESTRUCTURA. UTILIZACION EN PARTICULAR EN EL CAMPO DE LOS PRETENSORES EXTERNOS DESMONTABLES.THE INVENTION REFERS TO A COVER ELEMENT (35) PREPARED TO EXTEND THROUGH A PORTION (9) OF THE PRETENSED STRUCTURE IN AN ELEVATED PART OF A WINDING PATH THAT FOLLOWS THE PRETENSOR CABLE. THIS ELEMENT INCLUDES AN AIR CHANNEL (41) PARALLEL TO THE TUBULAR CAVITY (20) THAT RECEIVES THE CABLE BRIDGES AND IS SECTION CLEARLY LOWER TO THE TUBULAR CAVITY. THIS AIR CHANNEL IS MOUNTED WAY THAT, AFTER PLACING THE CASE ELEMENT (35) IN THE MENTIONED PORTION OF THE STRUCTURE, THE CHANNEL IS ABOVE THE TUBULAR CAVITY AND COMMUNICATES WITH IT IN A ZONE OF THE CASE ELEMENT SITUATED INSIDE SUCH PORTION OF THE STRUCTURE, AND WITH THE EXTERIOR OF THE CASE IN A REGION OF THE COVER ELEMENT SITUATED OUTSIDE OF THE MENTIONED PORTION OF STRUCTURE. USE IN PARTICULAR IN THE FIELD OF REMOVABLE EXTERNAL PRETENSORS.
