Abstract
1353972 Wall plugs A FISCHER 18 Aug 1971 [3 Sept 1970] 38760/71 Heading F2H A wall-plug for anchorage in a bore in soft or porous marerial comprises an open-ended sleeve formed by two shells 4a, 4b of U-shaped crosssection, a portion 11 of each longitudinal edge being inclined relative to the sleeve longitudinal axis to form two tapered recesses 9 at the leading end of the sleeve so that when an expansion member 7 is drawn into the sleeve the leading portions of the shells are forced away from each other. The expansion member 7 is cylindrical, may be a nut or a bolt head, and may have grooves to engage the inclined edges 11 of the shells. As shown, the sleeve is square in crosssection, the overlapping portions of the shells being joined at their rear ends by indentations 15 which form internal bosses to centre the bolt 5. Leading extensions 16 (Fig. 2) of the shells are bent inwards to form a nose preventing the expansion member 7 from being forced into the sleeve during insertion of the plug in a bore. In a modification (Fig. 4, not shown) a separate cap (18) engages the shells by flanges (20) which break as expansion of the plug begins. In Fig. 1 (not shown) the shells are of semicircular crosssection and are joined by interengaging tongues, or by spot welds.
