An anchorage system for structural reinforcement of surface bonded reinforcing sheet, plate or shell made of fiber reinforced plastic (FRP) or steel or other metallic or non- metallic materials is disclosed. The anchorage system comprises an anchor tube with a circular outer surface and a lock-down means provided along the longitudinal axis of the tube. The lock-down means can be either an anchor bolt mounted through the center of the anchor tube or an anchor strap pressed against the circular surface of the tube into the members to be reinforced. The FRP reinforcing sheet, plate or shell is bonded to the surface of the structural member and passes underneath the outer circular surface of the tube. The tube is held securely by the lock-down means which, in turn, compresses and holds in place the FRP sheet against the surface of the structural member.
On décrit un système d'ancrage pour renfort structurel d'une feuille, d'une plaque ou d'une coque de renfort collée à la surface et à base plastique renforcé de fibres (FRP) ou d'acier ou d'autres matériaux métalliques ou non métalliques. Le système d'ancrage comprend un tube d'ancrage avec une surface externe circulaire et un moyen de verrouillage prévu le long de l'axe longitudinal du tube. Le moyen de verrouillage peut être soit un boulon d'ancrage monté à travers le centre du tube d'ancrage, soit une bande d'ancrage pressée contre la surface circulaire du tube à l'intérieur des éléments à être renforcés. La feuille, la plaque ou la coque de renfort FRP est collée à la surface de l'élément struturel et passe au-dessous de la surface circulaire externe du tube. Le tube est maintenu fermement par le moyen de verrouillage qui, à son tour, comprime et maintient en place la feuille FRP contre la surface de l'élément structurel.
