Zusammenfassung:An expansion bolt assembly (22) for securing together sheets or plates (10, 12, 14) comprises a tapered pin (24) and a bush (32). In use, the bush (32) is disposed within aligned holes in the sheets or plates (10, 12, 14) and surrounds the tapered pin. The bush (32) is radially expandable so that when an axial force is applied to the tapered pin (24), the tapered pin (24) is drawn into the bush (32) and causes the bush (32) to radially expand to abut the sheets or plates (10, 12, 14) and prevent relative movement between the sheets or plates (10, 12, 14). The axial force may be applied by tensioning a nut and bolt arrangement (28, 30) or by a lever arrangement (see figure 8).
