Problems solved by technology

[0004] The disadvantage of the above-mentioned known solution is that, especially when the pin body is assembled through, the two pin parts may be loosened from each other before or during the introduction of the expansion element, that is to say, when the expansion element expands the expansion site to reach the base loosened before being fully anchored in

Embodiment Construction

[0025] In principle, the same parts in the various figures are denoted by the same reference numerals.

[0026] Figures 1 to 3 The expansion pin 11 shown in has a sleeve-shaped pin body 12, which extends along a pin longitudinal axis 13 and has: a first pin part 21 facing forward on one side in the installation direction, which has an expansion portion 22; a second pin portion 31 axially connected to the first pin portion, the pin portion having a shank portion 32; The two pin parts 21 and 31 can be passed through by an expansion element not shown in the figure, such as an expansion screw or an expansion nail, and can be connected to each other via a snap connection 41 . The first pin part 21 with the expansion point 22 is made of a high-quality plastic such as polyamide (PA). The second pin part 31 with the shank 32 is made of a less valuable plastic such as polyethylene (PE) or polypropylene (PP).

Abstract

A dowel (11) has a sleeve-shaped dowel body (12) with a dowel part (21) and another dowel part (31) axially adjoining the former dowel part. An expansion member is extended through the latter dowel part (21, 31). A snap connection device (41) connects the dowel parts together, wherein the connection device includes an engagement element (42) i.e. cam, on the latter dowel part (31). A receiving element (47) for the engagement element is provided on the former dowel part (21).

Description

technical field [0001] The invention relates to an expansion pin having a sleeve-shaped pin body with a first pin part and at least one second pin part axially connected thereto, wherein the two pin parts can be An expansion element runs through and can be connected to each other via a connecting device. Background technique [0002] In order to fasten the part on a building structure, such as a wall or a ceiling, such expansion pins are inserted through a hole in the part to be fastened, for example during a through-fitting, into a pre-drilled borehole, Also, for anchoring in the substrate, the drilled hole is expanded with an expansion element, such as an expansion screw. The pin body has a radially expandable extension and a shank connected thereto at one end of the pin body in the installation direction. In order to accommodate different thicknesses of the parts to be fastened, the pin bodies are available in different lengths. [0003] DE 199 28 633 A1 discloses an e...
