Abstract

L'invention concerne une cheville à noyau d'expansion destinée à être ancrée dans un support, comprenant un corps cylindrique formé d'une tête et d'une partie crurale entre lesquelles sont disposés des moyens d'appui de ce corps sur le support, la tête étant percée d'un canal axial se prolongeant partiellement dans la partie crurale, un noyau d'expansion étant logé dans le canal axial, et au moins une fente longitudinale de largeur inférieure à l'épaisseur du noyau étant d'écoupée dans la partie crurale pour ménager deux jambes déformables sous l'effet de l'enfoncement du noyau d'expansion dans le corps. La cheville de l'invention est caractérisée par le fait qu'un élément, destiné à être déformé par le noyau d'expansion lors de son enfoncement dans le corps de la cheville, est maintenu entre les jambes de la partie crurale du corps.The invention relates to an expansion core anchor intended to be anchored in a support, comprising a cylindrical body formed of a head and a crural part between which are arranged means for supporting this body on the support, the head being pierced with an axial channel extending partially in the crural part, an expansion core being housed in the axial channel, and at least one longitudinal slot of width less than the thickness of the core being cut in the crural part to provide two deformable legs under the effect of the depression of the expansion core in the body. The ankle of the invention is characterized in that an element, intended to be deformed by the expansion core when it is inserted into the body of the ankle, is held between the legs of the crural part of the body.
