Attachment device for mounting a pair of glass panes fixedly to a structure, such as a building

DETAILED DESCRIPTION The invention teaches that this object can be accomplished by a punctiform holder to connect insulating glass panels with at least two glass plates separated by an air gap that is preferably filled with a gaseous medium, and whereby the punctiform holder is also detachably or non-detachably connected to a substructure, characterized by the fact that the punctiform holder has a mounting element with a flat mounting surface which is detachably or non-detachably connected with an outside surface of the glass plates by adhesive and, in the air gap, in the vicinity of the punctiform holder, a spacer piece between the glass plates is also detachably or non-detachably connected with the glass plates by an adhesive.
Further features of the invention are described herein.
The invention teaches that the borings that are conventionally present in the glass plates are omitted, and the detachable or non-detachable connection of the punctiform holder, which has a flat mounting surface, to one of the separated insulating glass plates, is formed by means of an adhesive.
So that the weight of the insulating glass panel can also be supported securely by the punctiform holder even when there are two separated glass plates, in the air gap between the separated glass plates there is a spacer piece which is also detachably or non-detachably connected with the glass plates by an adhesive.
This spacer piece can thereby be made of glass or metal.
The adhesive used must be essentially UV-stable and preferably transparent.
It must also have long-term creep stability with regard to the load-bearing characteristics.
The proposed holder is also constructed so that it mounts the glass plates on a substructure in a manner that is free of bending moments.
This concept also applies to the adhesive connection between the proposed holder and the insulating glass panel.
The holder is therefore constructed so that it has an inside clamp element on its mounting surface that faces away from the glass plate in the form of a crown-shaped or curved surface formed by a permanently elastic flexible element, against which a complementary surface of an inner shell surface of a cap bell or coupling bell and a fastening bolt or attachment bolt can be placed in contact with an adjustable bias, whereby between the cap bell and the fastening bolt on one hand and the fastening bolt and the mounting on the other hand there are respective three-dimensional articulations that can be made rigid
