Anchor bolt and annularly grooved expansion sleeve assembly exhibiting high pull-out resistance, particularly under cracked concrete test conditions |
摘要 |
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. |
