1. Method for the assembly of an insulating plate (2) on a substructure (3) by means of a dowel (1) having a pressing plate (13) with a single outer circumference and a dowel sleeve (15) attached to said pressing plate (13) for taking up an expansion element (11) having an expansion element head (12), wherein the dowel sleeve (15) comprises an expansion zone (18), comprising at least the following steps:
a) drilling of a bore-hole (4) through the insulating plate (2) into the substructure (3),
b) inserting the dowel (1) and the expansion element (11) into the bore-hole (4),
c) driving in the expansion element (11) into the pressing plate (13) and the dowel sleeve (15) and simultaneously
d) pulling in the pressing plate (13) into the insulating plate (2) under compression of the insulating plate (2) and simultaneously cutting in the insulating plate (2) at the circumference of the pressing plate (13) by means of cutting devices (17) curved along a circumferential length to substantially follow said pressing plate outer circumference.
