MECHANICAL CONNECTION FOR REINFORCING RODS, CONNECTING SLEEVE PERMITTING THE IMPLEMENTATION OF THE SAID CONNECTION, REINFORCING ROD PERMITTING THE IMPLEMENTATION OF THE SAID CONNECTION, AND PROCESS FOR PRODUCING SUCH A CONNECTION

摘要

The invention relates to a mechanical connection for concrete reinforcing rods, a connecting sleeve permitting the implementation of the said connection, a reinforcing rod permitting the implementation of the said connection, and to a process for producing such a connection. It will find an application notably in the field of concrete element construction. According to the invention, the mechanical connection for concrete reinforcing rods wherein the reinforcing rods (1, 2) comprise, on one hand, ribs or fins on their outer surface and, on the other hand, each at least a threaded end (4, 5), designed to be inserted into a connecting sleeve (3) having tapped portions, is noteworthy in that it has means for allowing the end (4) of the first rod (1) to be connected to be passed completely through the sleeve (3), and for allowing the rotation of the sleeve (3) about the end (4) of the said first reinforcing rod (1) and, simultaneously, its screwing, directly or indirectly, onto the end (5) of the second reinforcing rod (2), the said ends (4, 5) of the said first and second rods (1, 2) being placed substantially coaxially, substantially end to end, and rotationally immobile.
