MECHANICAL CONNECTION FOR REINFORCING BARS, DEVICE FOR PLACING THIS MECHANICAL CONNECTION AND PROCESS FOR FIXING THE MECHANICAL CONNECTION FOR REINFORCING BARS

摘要

The invention relates to a mechanical connection for reinforcing bars, a device for placing this mechanical connection and a process for fixing the mechanical connection for reinforcing bars. According to the invention, the mechanical connection for reinforcing bars is characterised in that it comprises: - a bush (11) with a hollow cylindrical body into which the end of the bar not having a connecting element is introduced, - a thread (8) at the end of the bush (11), - the hollow body and the thread being coaxial so that two bars disposed end to end can be connected, - the outer material of the bush having been subjected to deformation by the formation of linear or helical indentations, - the material of the ribs (10) of the bar penetrating into the hollow body of the bush (11), in order to connect the bar and the bush. Used in building construction using concrete.
