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 forreinforcing bars, a device for placing this mechanicalconnection and a process for fixing the mechanical connectionfor reinforcing bars.According to the invention, the mechanical connection forreinforcing bars is characterised in that it comprises:- a bush (11) with a hollow cylindrical body into which the endof 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 barsdisposed end to end can be connected,- the outer material of the bush having been subjected todeformation by the formation of linear or helicalindentations,- the material of the ribs (10) of the bar penetrating into thehollow body of the bush (11),in order to connect the bar and the bush.Used in building construction using concrete.
