A method for the realization of mechanical concrete steel compounds, a compound according to this process, reinforcing steel for this method and device for machining the reinforcing steels

摘要

The invention relates to a method of implementation of a mechanical connection of the reinforcing bars as well as to such a mechanical connection and to a rod allowing the implementation of the process, and to an installation for the preparation of rods. & br / it will find its application in the field of the construction of concrete. & br / by the process, it is liaisonne at least one rod (1) to a rod (2), or to an anchoring point, by means of a sleeve (3) threaded connection, the said rod having a nominal section phi, and at least a reinforced end (4), pushed back and which is threaded, such as a thread root diameter d2 is greater than or equal to the nominal section phi of the round. & br / according to the invention, the reinforced end (4) by a double outlet, a first axial making it possible to increase the diameter of the rod, a second radial when the thread by means of a rolling technique.
