Patent

CA 2537538

The invention relates to a system for fixing an object in the ground, comprising at least one fixing peg (10) and means for carrying out the above. The peg (10) comprises a tube (14) and at least two lugs (28) on the lower end of a central support rod (24). An axial tension acting on the rod (24) which runs axially in the tube (14) and is fixed in rotation therein, causes the lugs (28) to deploy through openings (30) in the tube (14), such as to cause the extension thereof in the direction of tension at an angle to the length of the tube (14). An operating mechanism (33) comprises a threaded pin (36) with a screw (40) pressing on the head of the tube. The lower end of said threaded pin (36) is coupled to the upper end of the central support (24) in order to transmit an axial tension thereto on turning the screw (40) in a first direction.

Un système pour l'ancrage d'un objet dans le sol comprend au moins un piquet d'ancrage (10) et des moyens pour la mise en oeuvre de celui-ci. Le piquet (10) comprend un tube (14) et au moins deux griffes (28) portées par l'extrémité inférieure d'une tige centrale de support (24). Une traction axiale exercée sur la tige (24), qui est axialement guidée et bloquée en rotation dans le tube (14), fait sortir les griffes (28) au travers d'ouvertures (30) du tube (14), de façon à provoquer leur déploiement dans le sens de traction en biais le long du tube (14). Un mécanisme (33) d'actionnement comprend une tige filetée (36) avec un écrou (40) qui prend appui sur la tête de tube. L'extrémité inférieure de cette tige filetée (36) est accouplée à l'extrémité supérieure de la tige centrale de support (24) pour transmettre à celle-ci une traction axiale lorsque l'on fait tourner l'écrou (40) dans un premier sens.
