A wedge-type anchor assembly (110), capable of meeting cracked concrete testing standards, comprises an anchor bolt component (112) and a substantially C-shaped expansion sleeve component (114) annularly disposed about the anchor bolt component. A plurality of annular grooves (138), threads, or teeth are disposed only about the forward end portion of the expansion sleeve component. The expansion sleeve component may be plated with a tin-zinc (Sn-Zn) composition, and the rear end portion of the expansion sleeve component may have a larger diametrical extent (D) than the forward end portion of the expansion sleeve component so as to enhance pull-out resistance.
La présente invention concerne un ensemble dispositif dancrage du type cale (110), capable de satisfaire les normes dessai du béton fissuré, comprenant un composant boulon dancrage (112) et un composant coquille dexpansion sensiblement en forme de C (114), disposé de manière annulaire autour du composant boulon dancrage. Une pluralité de rainures annulaires (138), de filets, ou de dents est disposée uniquement autour de la partie dextrémité avant du composant coquille dexpansion. Le composant coquille dexpansion peut être plaqué avec une composition étain-zinc (Sn-Zn), et la partie dextrémité arrière du composant coquille dexpansion peut présenter une étendue diamétrale (D) plus importante que celle de la partie dextrémité avant du composant coquille dexpansion de manière à améliorer la résistance à larrachement.
