Publication number: 20220170496Abstract: A fastener includes an anchor bolt and a nut. The nut has a nut hole and an internal thread. The anchor bolt has an anchor portion and a threaded rod that has an external thread and that is connected to the anchor portion. The nut is arranged on the threaded rod and the internal thread of the nut threadedly engages the external thread of the threaded rod. The nut has a rearward nut section, a forward nut section, and an outside shoulder for load transfer into the nut which is located between the forward nut section and the rearward nut section and which faces the anchor portion of the anchor bolt. The internal thread of the nut extends at least in the forward nut section and threadedly engages the external thread of the threaded rod at least in the forward nut section.Type: ApplicationFiled: March 17, 2020Publication date: June 2, 2022Inventors: Christoph WIEDNER, Vincent DE GROOF, Frederik KORTE, Juergen GEBHARD, Juergen BOECKLE, Kay HEEMANN

Patent number: 8234832Abstract: The present invention relates to a cast-in channel having a channel body which forms a receiving space for receiving a connecting element used to fixedly attach a fastening element to the cast-in channel, the channel body further being provided with holes, the holes having connectors provided therein for fixedly attaching anchoring members to the channel body. The connectors are designed as rivets, whose fixing portions, which are inserted through the respective holes, are expanded so as to secure the rivets to the channel body, and which have an attachment for fixedly attaching the anchoring members to the channel body. The present invention also relates to a rivet nut for a cast-in channel.Type: GrantFiled: December 16, 2009Date of Patent: August 7, 2012Assignee: Hilti AktiengesellschaftInventors: Ulrich Birnbaum, Juergen Gebhard, Markus Heudorfer, Harald Schachinger, Erich Spreizer, Denis Novokshanov
