    • The invention relates to an expansible anchor (10) for anchoring in a cylindrical drilled hole (40). The invention proposes constructing the expansible anchor (10) with a tubular basic anchor part (12), on which a hollow conical expansion portion (22) is formed by means of a forming procedure, on which expansion portion (22) an expansion sleeve (14) bent out of sheet metal is mounted. As a result of axial displacement of the expansion sleeve (14) on the expansion portion (22), the expansible anchor (10) becomes anchored in the drilled hole (40). The expansible anchor (10) exhibits subsequent expansion behaviour in the event of widening of the drilled hole (40), for example as a consequence of crack formation.
    • 本发明涉及一种用于锚固在圆柱形钻孔(40)中的可膨胀锚(10)。 本发明提出用管状基础锚固部件(12)构造可膨胀锚固件(10),借助于成形程序在其上形成中空圆锥形膨胀部分(22),膨胀部分(22)上有膨胀套管 14)弯曲的金属板被安装。 由于膨胀套筒(14)在膨胀部分(22)上的轴向位移,可膨胀锚固件(10)被锚固在钻孔(40)中。 可扩展锚(10)在钻孔(40)变宽的情况下表现出随后的膨胀特性,例如作为裂纹形成的结果。

    • The impact-type anchor (1) consists of a metal sleeve (2) provided with a throughgoing passage (3) tapering towards a leading end of the sleeve, into which bore an expander body (5) can be driven to expand the impact-type anchor. The throughgoing passage (3) has a rear cylindrical portion provided with an internal thread (4) as well as a tapering portion. So that the metal sleeve can be inexpensively manufactured while providing pull-out values that are the same as those of a metal sleeve made of solid material, the metal sleeve is stamped out of a sheet metal blank and then rolled up to form a sleeve which is joined at its seam. Furthermore, in order to form the tapering internal bore the expandable legs (7) have a first section (7a) that is bent inwards and a second section (7b) that is bent onto the outer face of the first section. The two sections (7a, 7b) resting one against the other are connected non-displaceably to one another, for example, by means of a punched point (9).
    • 所述冲击式锚固件(1)由金属套筒(2)组成,所述金属套筒(2)设置有朝着所述套筒的前端逐渐变细的通孔(3),所述孔可以被驱动以使膨胀机体(5) 键入锚。 通过通道(3)具有设置有内螺纹(4)的后圆柱形部分和锥形部分。 因此,金属套筒可以廉价地制造,同时提供与由固体材料制成的金属套筒相同的拉出值,金属套筒从金属板坯料冲压出来,形成套筒, 在其接缝处加入。 此外,为了形成锥形内孔,可膨胀腿(7)具有向内弯曲的第一部分(7a)和弯曲到第一部分的外表面上的第二部分(7b)。 彼此靠在一起的两个部分(7a,7b)例如通过冲压点(9)彼此不可移位地相互连接。
