Two-part expanding fixing device - has protrusions on initially inserted component limiting amount of penetration

The two-part fixing device is expanded in a drilling and comprises two U-shaped components with parallel arms. These fit together with their arms in intersecting planes in the axial direction, so that the arms of one at least are caused to spread apart. The component (1) first inserted in the drilli...

Zusammenfassung:	The two-part fixing device is expanded in a drilling and comprises two U-shaped components with parallel arms. These fit together with their arms in intersecting planes in the axial direction, so that the arms of one at least are caused to spread apart. The component (1) first inserted in the drilling has at its rear end protrusions (1b) bearing against the outer surface of the wall. This limits the amount of its penetration into the wall. L'INVENTION CONCERNE UN ELEMENT DE FIXATION EN DEUX PARTIES POUR UNE EXPANSION DANS UN TROU DE PERCAGE.L'ELEMENT EST CARACTERISE PAR LE FAIT QUE LA PARTIE SITUEE DU COTE FOND 1 ET QUI DOIT ETRE INTRODUITE LA PREMIERE DANS LE TROU DE PERCAGE COMPORTE, A SON EXTREMITE ARRIERE, DES SAILLIES 1B S'APPUYANT CONTRE LA PAROI ET S'OPPOSANT A UNE PENETRATION AXIALE SUPPLEMENTAIRE DE LADITE PARTIE DANS LE TROU DE PERCAGE.APPLICATION NOTAMMENT AU DOMAINE DE LA CONSTRUCTION.
