The invention relates to a dowel for fastening to planar components (100) having a first (101) and a second (111) cover panel and at least one intermediate support core layer (121), wherein the dowel comprises at least one expansion body (10) (which accommodates at least one fastening means) and at least one wedge body (60) guided in the expansion body. The placed dowel fits in a cutout (130) which passes virtually right through the planar component. The placed dowel engages behind the first cover panel by way of at least one rear-engagement element (42). At least two dowel-side clamping elements bear in a radially clamped manner in the lower region of the cutout. The dowel has at least one cavity (49, 59) - for accommodating a relatively large number of adhesive-containing balloons (3, 4) - with at least one opening (43, 53), wherein the maximum width of the individual opening is smaller than the diameter of the smallest balloon. The dowel developed with the present invention is one which, apart from being simple to mount, holds firmly, securely and permanently in the lightweight building panel. |
