Abstract (en)
1. Process for the restoration of wooden beams, employing reinforcing rods, epoxy resin and epoxy mortar, during which reinforcing rods are positioned longitudinally of the beam and other reinforcing rods are disposed substantially perpendicularly of the first rods, the various reinforcing rods being positioned in seatings previously drilled in the beam and made fast with the wood by injection or pouring of resin or epoxy mortar into the interior of the seatings, characterised in that at least one metallic reinforcing rod (3, 9) is positioned in the length direction of the beam and in that glass fibre rods (15, 16) are disposed in seatings drilled beforehand in the beam, the glass fibre rods being so positioned that at least one of their ends is free and in the vicinity of the metal rod (3, 9) and in that then, by injection or pouring, the metal rod (3, 9) and the ends of the glass fibre rods (15, 16) are coated in a mortar mass (6, 10, 12), the body of each of the glass fibre rods, in its seating, being made fast with the beam by the epoxy resin.
