摘要： An expansion dowel assembly includes an axially elongated expansion sleeve with an axially extending expansion region, a spreader positioned within the sleeves in the expansion region, and a bolt in threaded engagement within a tapped bore in the spreader so that the spreader can be displaced axially through the expansion region for widening it in the radial direction. The surface of the spreader in surface contact with the interior of the sleeve is spherically shaped. In the assembled state, before expansion, the spreader is held in the expansion sleeve against axial displacement. Accordingly, the parts of the assembly can be preassembled as a unit.
摘要翻译：膨胀销组件包括具有轴向延伸的膨胀区域的轴向细长的膨胀套筒，定位在膨胀区域中的套筒内的吊具以及在扩张器中螺纹接合在螺纹孔内的螺栓，使得吊具可以轴向地穿过用于在径向上使其扩宽的扩张区域。与套筒内表面接触的吊具的表面是球形的。在组装状态下，在膨胀之前，吊具保持在膨胀套筒中以防止轴向位移。因此，组件的部件可以预先组装成一个单元。

摘要： An expansion anchor is used in a hole in a receiving material where the hole is undercut. The expansion anchor includes an axially elongated anchor sleeve containing slots extending in the axial direction. Expansion interlock members are radially displaceably mounted in the slots. A fastening bolt can be threaded into the sleeve so that it radially displaces and secures the interlock members in the undercut portion of the hole. Each interlock member has a shaped surface facing radially inwardly in the sleeve and the shaped surface is contacted by the fastening bolt as it is moved into the sleeve. The trailing end of the shaped surface is formed so that it is not contacted by the fastening bolt as the bolt is moved through the sleeve.
摘要翻译：在孔底切的接收材料的孔中使用膨胀锚。膨胀锚固件包括轴向细长的锚固套筒，其包含在轴向方向上延伸的槽。扩展互锁构件可径向移动地安装在槽中。紧固螺栓可以被拧入套筒中，使得其将互锁构件径向移位并固定在孔的底切部分中。每个互锁构件具有在套筒中径向向内面对的成形表面，并且当紧固螺栓移动到套筒中时，成形表面与紧固螺栓接触。成形表面的后端被形成为使得当螺栓移动穿过套筒时，其不被紧固螺栓接触。
