    摘要： A spreading anchor (1) including an anchor rod (2) provided at its front end, when viewed in a setting direction, with a head (3, 30) having at least several regions, which taper outwardly in the setting direction, and extending through an axial through-bore of an expansion sleeve(5) axially displaceable along the anchor rod (2, 20) and having a plurality of axial longitudinal slots (7) extending from a front end of the expansion sleeve (2, 20) and forming at least two, located opposite each other expansion tabs (6) provided at their free front ends with cutters (16), the spreading anchor (1) being supported against an upper surface of a ground (G) and further including rotation-transmitting driver elements for transmitting axial rotation, which is generated during setting of the anchor rod (2, 20), to the expansion sleeve (5).

    摘要： A compound anchor and method for joining concrete parts is disclosed. The compound anchor has a rod-shaped anchor body and a compensator component, which has at least one deformable element and is situated to be movable at least axially in relation to the anchor body. A first section of the anchor body is accommodated in a first concrete part and a second section having the compensator component is accommodated in a second concrete part. Openings are formed in the concrete parts so that a blind hole is formed in the first concrete part and a through-opening is formed in the second concrete part. The first section of the anchor body is secured in the blind hole and the second section having the compensator part is in the through-opening. The through-opening is then filled with a cement so that the second section is secured in the second concrete part.

    摘要翻译： 公开了一种用于连接混凝土部件的复合锚和方法。 该复合锚具有一个棒状的锚固体和一个补偿器部件，该部件具有至少一个可变形元件并且被定位成可以相对于锚固体至少轴向移动。 锚固体的第一部分容纳在第一混凝土部分中，并且具有补偿部件的第二部分容纳在第二混凝土部分中。 开口形成在混凝土部分中，使得在第一混凝土部分中形成盲孔，并且在第二混凝土部分中形成通孔。 锚体的第一部分固定在盲孔中，具有补偿器部分的第二部分处于通孔中。 然后用水泥填充通孔，使得第二部分固定在第二混凝土部分中。
