Abstract

Procédé de renforcement de poutres de bois comportant au moins les stades successifs suivants : mise en contact mutuel des deux poutres (1, 2) à réunir avec intercalation d'une couche de fibres (3); perçage d'une pluralité de trous d'ancrage (4) à travers les deux poutres et la couche de fibres; introduction de tiges d'armature (5) dans les trous ainsi obte­ nus; obturation des joints entre les deux poutres; et introduc­ tion par coulage ou par injection d'une résine époxy ou d'un mélange de résines époxy dans lesdits trous d'ancrage (4) jusqu'à leur remplissage total et jusqu'a l'imprégnation totale de la couche de fibres (3). Poutres ainsi obtenues. Method for reinforcing wooden beams comprising at least the following successive stages: contact mutual of the two beams (1, 2) to be joined with intercalation a layer of fibers (3); drilling a plurality of holes anchoring (4) through the two beams and the layer of fibers; introduction of reinforcing rods (5) into the holes thus obtained naked; sealing the joints between the two beams; and introduc tion by casting or injecting an epoxy resin or a mixture of epoxy resins in said anchor holes (4) until their complete filling and until the total impregnation of the fiber layer (3). Beams thus obtained.
