    • When it comes to an expansion plug (1) including an anchor bolt (2) with an expansion element (3) on a first end section (6) of the anchor bolt (2) having a longitudinal axis (10), preferably also including at least one force-applier (20) on the anchor bolt (2) in order to hold loads, and also including an expansion sleeve (4) surrounding the anchor bolt (2), the objective is to avoid an axial movement of the expansion sleeve (14), especially in the case of a drilled hole diameter in the lower tolerance range or in the case of a hollow space. The expansion plug (1) has at least one eccentric geometry, so that an expansion of the expansion sleeve (4) can be achieved by a rotational movement of the anchor bolt (2), especially around the longitudinal axis (10) as the axis of rotation (9).
    • 当涉及具有纵向轴线(10)的锚定螺栓(2)的第一端部(6)上的具有膨胀元件(3)的锚定螺栓(2)的膨胀塞(1)时,优选还包括 至少一个施力器(20)位于锚定螺栓(2)上以便保持负载,并且还包括围绕锚定螺栓(2)的膨胀套筒(4),该目的是避免膨胀的轴向运动 套筒(14),特别是在钻孔直径在较低公差范围内或中空空间的情况下。 膨胀塞(1)具有至少一个偏心几何形状,使得膨胀套筒(4)的膨胀可以通过锚定螺栓(2)的旋转运动来实现,特别是围绕纵向轴线(10),作为轴线 的旋转(9)。
