  • Patent number: 6308478
    Abstract: The invention relates to a device enabling reinforced concrete elements (1, 2) to be linked by means of metal cables, certain portions of which are inserted into the just made concrete (1) while the cable portions which are not inserted protrude into the enclosure formed by the second contiguous concrete element (2). The first concrete element (1) presents a reinforcement which terminates in the area of contact with the second concrete element (2). In parallel or extension to said reinforcement of the first concrete element, pieces of metal cable (4) are inserted so as to provide either spaces for locating the cable free ends in the first concrete element, or passages in the enclosure formed by said first concrete element.
