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.
Claims21
A device comprising at least two reinforced concrete sections and formwork for making each of the concrete sections, wire ropes being provided to connect the concrete sections, some of the wire ropes being embedded partially in one of said concrete section, and the other ends protrude into the formwork of the second, adjoining, concrete section, wherein the first concrete section having a reinforcement and said reinforcement including bars which terminates in the adjoining region of the second concrete section, wire rope pieces arranged parallel to the reinforcement or as an extension of the reinforcement in the first concrete section which when the concrete sections are under load take over and transmit the tensile forces of the reinforcing bars, and for the free ends whereof there are provided receiving spaces in the first concrete section.
A process for creating a connection between at least two reinforced concrete sections, using wire rope pieces which are embedded partially one of said concrete sections which was made first and whereof part of said wire rope pieces are free and protrude into a formwork of the second concrete section which is to be attached, bending the free ends of the wire rope pieces out from receiving spaces of that concrete section which was made first and laying the wire rope pieces parallel to or as an extension of the reinforcement, which comprises bars, of the second concrete section into the formwork of this second concrete section and the formwork is then filled with concrete.
