主权项

1. An anchor for installation in a lightweight construction panel (100) including first and second spaced hard-material cover plates (101, 111) with a support core structure (121) disposed between the first and second cover plates (101, 111), the anchor being insertable into a support bore (130) formed in the construction panel (100) so as to extend through the first cover plate (101) and through the support core (121) and into a dead end bore (115) extending into the second cover plate (111), said anchor comprising an expansion body (10) including a mounting means and a wedge body (60) movably disposed in the expansion body (10), the expansion body (10) having an upper seating section (20) with an essentially cylindrical zone (21) for accommodation at least partly in a bore section (105) of the support bore (130) extending through the first cover plate (101), an intermediate area forming an engagement section (40) with at least two integral elastically inwardly flexible engagement elements (42) formed at the upper end thereof and a lower area forming a spreading section (50) with at least two clamping elements (52) extending downwardly for accommodation in the dead end bore (115) of the second cover plate (111), said wedge body (60) with the anchor uninstalled being disposed in an accommodation section next to a downwardly narrowing cavity (51) formed in the expansion body (10), said anchor, when inserted into the support bore (130) being in engagement at its top with the first cover plate (101), with the engagement elements (42) being spread out behind the first cover plate (101) in contact with the first cover plate (101) and the clamping elements (52) being spread apart by the wedge body (60) moved into the narrowing cavity (51) into firm radical engagement with the second cover plate (111).
