Abstract

La figure montre une barre d'ancrage foncée et scellée 1 déjà définitivement incorporée à la roche. Dans le présent exemple, la barre d'ancrage scellée se compose des tronçons 1a, 1b, 1c et 1d et est scellée sur toute sa longueur dans le trou de forage 2 au moyen d'un mélange adhésif 3 de résine synthétique ou de mortier de ciment, de sorte qu'elle est réunie rigidement à la roche. On voit que les tronçons 1a, 1b, 1c et 1d sont totalement identiques dans leur forme L'assemblage de deux tronçons adjacents est obtenue par coopération de surfaces, en forme de coin, dont l'une comporte une broche radiale engagée dans un trou correspondant de l'autre.The figure shows a dark and sealed anchor bar 1 already permanently incorporated into the rock. In the present example, the sealed anchor bar consists of sections 1a, 1b, 1c and 1d and is sealed along its entire length in the borehole 2 by means of an adhesive mixture 3 of synthetic resin or of mortar. cement, so that it is rigidly joined to the rock. It can be seen that the sections 1a, 1b, 1c and 1d are completely identical in their shape The assembly of two adjacent sections is obtained by cooperation of surfaces, in the form of a wedge, one of which comprises a radial pin engaged in a corresponding hole the other.
