Problems solved by technology

[0004] A disadvantage of this known solution is that, for the radial expansion of the expansion sleeve, a high installation energy is required due to the abutment of the expansion tabs on the conical surface between the ribs

Embodiment Construction

[0033] exist Figure 1~4 The multi-part expansion pin 11 described in has a pin body 12 with a longitudinal axis 13, an expansion body 21 is arranged on the first end 14 of the pin body, and an expansion body adjacent to the expansion body 12 Arranged in the direction of the second end 15 is an expansion sleeve 31 delimiting an interior space 32 . Adjacent to the second end 15 , the pin body 12 has a threaded section 18 for a nut 19 which is depicted here with dashed lines.

[0034] The expansion sleeve 31 as a first part of the expansion pin 11 has three and thus an odd number of expansion discs 35 as elements of the expansion sleeve, which are separated from one another by longitudinal slots 34 . The expansion sleeve 31 partially surrounds the pin body 12 and is adjacent to the expansion body 21 . At a distance from the expansion body 21 , a step 16 is provided on the pin body 12 , which step forms an abutment section 17 for the expansion sleeve 31 to abut against the end ...

Abstract

The invention relates to a multi-part expansion anchor (11), which has, as a first part, an expansion sleeve (31) which has, as its elements, several expansion tabs (35) that are separated from each other by elongated slots (34) and has, as a second part, an expansion body (21) that can be pulled into the expansion sleeve (31), and a conical portion (22) for purposes of radially widening the expansion sleeve (31). The conical portion (22) has, as its elements, edges (24) running along the longitudinal axis (13). One of the parts of the expansion anchor (11) has an even number of appropriate elements, while the other part of the expansion anchor (11) has an odd number of appropriate elements.

Description

technical field [0001] The invention relates to a multi-part expansion pin of the type stated in the preamble of claim 1 . Background technique [0002] Such multi-part expansion pins are installed in previously drilled holes in the foundation, for example in the wall or ceiling of the component. The expansion sleeve is radially expanded by drawing the expansion body into the expansion sleeve and the expansion pin is anchored in the foundation. [0003] From EP 1 243 801 B1 a multi-part expansion pin is known which has as a first part an expansion sleeve which has a plurality of expansion plates separated from one another by longitudinal slots as the expansion sleeve. element, and the expansion pin has an expansion body as a second part, which can be drawn into the expansion sleeve and has a conical section for radial expansion of the expansion sleeve, the conical section has a length extending along the longitudinal axis Ribs as its components. The number of ribs of the ...
