Title (EN) EXPANDING PLASTIC PLUG
(FR) CHEVILLE EXTENSIBLE EN MATIERE SYNTHETIQUE
Abstract:
(EN) The plug has a sleeve-shaped body (1) and two expanding parts (2) integrally connected with the body (1) and mutually separated by a longitudinal slot (7). Projecting from each expanding part (2) is a securing element which extends beyond the free end (5) of the body (1). When the plug rotates the securing elements (3) are wrapped around the body (1) and lodge between the body (1) and the drilled hole, so that the plug is immobilized. The plug is suitable in particular for use in soft or porous material such as tufa, foam concrete or brick.
(FR) La cheville présente un corps (1) en forme de douille et deux éléments extensibles (2) en une pièce solidaires du corps (1) et mutuellement séparés par une rainure longitudinale (7). Un élément de sécurité (3) s'écarte de chaque élément d'écartement (2) et recouvre l'extrémité libre (5) du corps (1). Par rotation de la cheville, les éléments de sécurité (3) s'enroulent autour du corps (1) et se coincent entre le corps et la paroi du trou, de sorte que la cheville est arrêtée. Cette cheville convient particulièrement bien pour son utilisation dans une matière tendre et poreuse comme le tuf, le béton-mousse ou la brique.
