Abstract

La présente invention concerne un procédé et un outil pour réaliser un trou dans du béton armé. Conformément au procédé, on perce le trou dans le béton 10 avec un foret hélicoïdal entraîné par une perceuse du type à percussion, on arrête le perçage lorsque le foret vient en contact d'un fer d'armature 11 et substitue au foret un trépan 15 comportant une surface de guidage 20 coopérant avec le trou précédemment foré et des arêtes de coupe disposées annulairement, on reprend le ponçage avec le trépan jusqu'au moment où on a dépassé le fer 11 puis substitue à nouveau au trépan le foret hélicoïdal et ainsi de suite. L'invention a égale ment pour objet le trépan pour la mise en oeuvre du procédé. L'invention permet de réaliser dans le béton armé des trous recoupant les fers d'armature sans endommager le foret et sans déviation du trou par les fers d'armature.The present invention relates to a method and a tool for making a hole in reinforced concrete. According to the method, the hole is drilled in the concrete 10 with a twist drill driven by a percussion type drill, the drilling is stopped when the drill comes into contact with a reinforcing iron 11 and the drill is replaced by a bit 15. comprising a guide surface 20 cooperating with the previously drilled hole and cutting edges arranged annularly, the sanding is resumed with the bit until the moment when the iron 11 has been passed and then the twist drill is replaced again by the twist drill and thus after. A subject of the invention is also the drill bit for carrying out the method. The invention makes it possible to produce holes in the reinforced concrete intersecting the reinforcing bars without damaging the drill and without deviating the hole by the reinforcing bars.
