Abstract:
1. An anchor for attachment to a lightweight construction panel ( 100 ) which includes at least one cover plate ( 101 ) of predetermined thickness, the anchor having a base body ( 1 ) with a front and a rear, end provided with an upper radial clamping section ( 10 ) having an axial length adapted to correspond to a thickness of the at least one cover plate ( 101 ) of the lightweight construction panel with which the anchor is intended to be used, the upper radial clamping section ( 10 ) of the base body ( 1 ) comprising an upper zone ( 20 ) disposed adjacent the rear end of the anchor and provided with axial grooves ( 30 ) and teeth ( 31 ), and a lower zone ( 40 ) having a transversely oriented arrangement of annular grooves ( 50 ) and at least two circumferential webs ( 51 ), with each circumferential web ( 51 ) having an axially inclined slide flank ( 52 ) and a planar locking flank ( 53 ), the axially inclined slide flanks ( 52 ) of the webs ( 51 ) forming a truncated cone-shaped surface area having a virtual tip disposed, in an axial direction ( 6 ) of the base body ( 1 ), spaced from the clamping section ( 10 ) on a center line ( 5 ) toward the front end of the anchor and at a distance providing for a cone angle of the truncated cone-shaped surface area of at least 70°, and the clamping section ( 10 ) of the anchor ( 1 ) consisting of a tough elastic material having an E modulus of less than 2000 N/mm 2 .
