Patent number: 10584731Abstract: An expansion anchor with a bolt and at least one expansion element is disclosed. An oblique surface is arranged in the region of the first end of the bolt and forces the expansion element radially outward on the bolt if the bolt is displaced in a pull-out direction relative to the expansion element. The bolt has, in the region of its rear end facing away from the first end, a load-absorber which is suitable for introducing tensile forces which are directed in the pull-out direction into the bolt. A plurality of grooves that are closed with respect to the first end of the bolt are disposed in the oblique surface and the plurality of grooves reduce a contact surface between the expansion element and the oblique surface. The contact surface between the expansion element and the oblique surface is reduced by the plurality of grooves by 20 to 50%.Type: GrantFiled: December 6, 2017Date of Patent: March 10, 2020Assignee: Hilti AktiengesellschaftInventors: Peter Gstach, Bernhard Winkler, Matteo Spampatti
