  • Publication number: 20220412390
    Abstract: A sleeve for receiving at least a portion of a fastening element is provided. The sleeve comprises an inner thread, which is partially formed by a helical notch within the sleeve, wherein the notch comprises restrictions in direction of a first and a second end of the sleeve. Furthermore, the inner thread comprises, at the area of a first turn adjacent to the first end of the sleeve, a restriction in direction of the second end, but no restriction in direction of the first end. Also, a system comprising a sleeve and a fastening element as well as a mandrel for manufacturing a sleeve are provided.

  • Patent number: 11313394
    Abstract: A fixing disc (1) for initially fixing a fastening element (2) in an opening of a component to be fastened, in particular a facade panel, during mounting of the fastening element (2) and for cutting into and/or removing a defined region of a protective film on the component to be fastened during mounting of the fastening element (2) is described. The fixing disc (1) has a fixing means for initially holding the fastening element (2) in a predetermined position relative to the opening during mounting of the fastening element (2), at least one connecting means (4) for at least temporarily producing a connection between the fixing disc (1) and the fastening element (2), and at least one cutting and/or friction means (5) on that side of the fixing disc (1) which faces the component to be fastened.

  • Patent number: 8250823
    Abstract: The invention relates to a dowel having cutting devices at the lower side of the pressing plate at the circumference of said pressing plate for cutting into the insulating panel when the pressing plate is pulled into the insulating panel. The invention further relates to a method, in which a bore-hole is drilled through the insulating panel into the substructure, the dowel and the expansion element are inserted into the bore-hole, the expansion element is driven into the pressing plate and the dowel sleeve, and wherein simultaneously the pressing plate is pulled into the insulating panel under compression of the insulating panel, and the insulating panel is cut in at the circumference of the pressing plate by means of cutting devices.

  • Patent number: 7320179
    Abstract: A method in which a bore-hole is drilled through an insulating panel into a substructure, a dowel having cutting devices at the circumference of the lower side of the pressing plate and an expansion element are inserted into the bore-hole, and the expansion element is driven into the pressing plate and the dowel sleeve. The pressing plate is pulled into the insulating panel under compression of the insulating panel which is simultaneously cut at the circumference of the pressing plate. A method also drills through the insulating panel into the substructure, cuts a circle with at least the radius R into the insulating panel by cutting devices, with the dowel and the expansion element inserted into the bore-hole. The expansion element is driven into the pressing plate and the dowel sleeve, and simultaneously the pressing plate is pulled into the insulating panel under compression of the insulating panel.
