Title: FASTENING ELEMENT WITH A NON-PERMEABLE ADHESIVE RING
Abstract:
A method for attaching a basic body (12) of a fastening element (10) to a surface (18), said basic body being designed to connect objects to the surface (18), wherein the method comprises the following steps: arranging the basic body (12) in contact with the surface (18), wherein the basic body (12) is connected to the surface (18) using an adhesive ring (20), and therefore the surface (18), the adhesive ring (20) and a gap present therebetween form airtight barriers of a space (16) arranged between said surface, adhesive ring and gap and the basic body (12), wherein the basic body (12) has at least one air- and/or water-permeable connection between the space (16) and an outer side of the basic body (12), which outer side is separated from the space (16) by the basic body (12), or the basic body (12) already contains moisture when said basic body (12) is arranged on the surface (18), the moisture being able to be provided for the quantity of adhesive (22); introducing an adhesive into the space (16) such that the latter is filled with a quantity of adhesive (22) which has a contact surface with the basic body (12); starting a curing process of the quantity of adhesive (22) by providing moisture for the quantity of adhesive (22) located in the space (16), wherein, prior to the starting of the curing process or/and during the curing process, the adhesive ring (20) and the quantity of adhesive (22) are heated in such a manner that some of the quantity of adhesive (22) located in the region of the contact surface forms an insulating layer (22a) which is cured homogeneously extensively over and beyond the contact surface and constitutes a further airtight barrier for the remaining part of the quantity of adhesive (22b) which has not yet cured. The invention furthermore comprises a fastening element (10) suitable for this purpose.
