Abstract

La vis pour béton décrite par l’invention réduit le couple moteur nécessaire, les ruptures par cisaillement et améliore la résistance à l’arrachage. Cette vis présente deux filetages différents, le diamètre du filetage principal étant plus grand que le diamètre du filetage secondaire, les filetages ayant un écart de pas au moins égal au diamètre de la tige de vis. Des sillons hélicoïdaux à sens de rotation opposé par rapport aux filetages se prolongent sur la longueur de la partie filetée de la vis et présentent un écart de pas d’au moins deux fois le diamètre de la tige de vis. Des sillons de contre-rotation hélicoïdaux intermédiaires sont présents sur une partie limitée adjacente au bout de la vis et couvrent en général tout au plus le tiers de la longueur des filets. Les sillons intermédiaires peuvent être adjacents aux sillons principaux pour réaliser une encoche en forme de W dans les filets. L’encoche en forme de W est, de préférence, asymétrique dans le sens de rotation des sillons.
