Description

[0033] In the following, the invention is explained in detail with reference to drawings and exemplary embodiments. The drawings are a schematic representation and are not true to scale. The drawings in no way restrict the invention.

[0034] They depict:

[0035] FIG. 1 a perspective view of two insulated glass elements according to the invention,

[0036] FIG. 2 a perspective view of a corner assembly of two insulated glass elements according to the invention,

[0037] FIG. 3 a sectional view of an insulated glass element according to the invention,

[0038] FIG. 4 a sectional view of the corner assembly of two insulated glass elements according to the invention.

[0039] FIG. 1 depicts a perspective view of the insulated glass elements 1a, 1b according to the invention. An insulated glass element includes two panes that are joined via a spacer profile. The spacer profile spaces, in the edge region, the parallel arranged panes at a constant distance from one another and is mounted peripherally on at least three sides of the panes. The spacer profile can consist, for example, of a simple hollow metal profile that is provided with a molecular sieve to dehumidify the interpane space formed between the panes. The panes are attached to the spacer profile using an adhesive such that the spacer profile substantially contributes to the mechanical strength of the insulated glass element 1a, 1b. Polyisobutylene is frequently used as an adhesive that simultaneously also has a sealing function for the insulated glass elements 1a, 1b.

[0040] Also, the insulated glass element 1a, 1b can include sealing means that are provided to seal the insulated glass element against moisture. Gas-tightness is also of significant importance for the insulated glass elements 1a, 1b especially when the interpane space is filled with a thermal insulating gas, e.g., argon.

[0041] The outwardly facing pane 3a in a building faade protrudes beyond the pane 3b facing the building such that the abutment region of the insulated glass elements 1a, 1b, is implemented like a miter. The miter can correspond to a bisector, e.g., 45, of the angle at which the insulated glass elements are attached, e.g., 90. In the region of their abutment ends, the panes are mitered. The pane 3a protrudes beyond the pane 3b only to the extent that the edges of the miter-shaped ends of the panes lie in a common plane.

[0042] The miter planes of the panes 3a, 3b have an acrylate adhesive. By means of the acrylate adhesive, a film 4 adheres in an edge-flush manner on the miter planes of the panes 3a, 3b. The film 4 joins the panes 3a and 3b. The width of the film 4 can correspond substantially to the width of the mitered abutment ends plus the width of the interpane space of an insulated glass element and is provided to hermetically seal the interpane space of the insulated glass element. The film 4 is made of polypropylene (e.g., PET) and can be reinforced in its load capacity by fibers. Moreover, it is possible for the film to be made of a mixture of materials such as plastic and metal.

[0043] The insulated glass elements 1a and 1b are structured virtually identically.

[0044] FIG. 2 depicts a perspective view of a corner assembly 2 according to the invention made of the two insulated glass elements 1a and 1b. The corner assembly 2 is made of the two insulated glass elements 1a and 1b abutting each other at an angle of 90. On the abutment ends of the insulated glass elements 1a, 1b, the spacer profiles arranged between the panes 3a, 3b are form-fittingly bonded to one another using an adhesive.

[0045] FIG. 3 depicts a horizontal sectional view (A) of an insulated glass element 1a according to the invention. The insulated glass element la includes two panes 3a and 3b. The pane 3a can face outward on site and the pane 3b is positioned inward. The panes 3a and 3b are not mandatorily monolithic panes. The panes 3a and 3b can be implemented as insulating glass or composite glass or as a combination thereof. It is also possible to use combinations of glass and plastic panes.

[0046] The panes 3a and 3b can in each case have a thickness of 3 mm to 19 mm.

[0047] The outwardly oriented pane 3a protrudes beyond the building-side oriented pane 3b such that their miter planes lie in a common plane. The common plane can also be referred to as an extended common miter plane. The film 4 is arranged in the common miter plane. The film 4 adheres by means of the acrylate adhesive 5 to abutment ends of the panes 3a and 3b. The film 4 is implemented in an edge-flush manner on the insulated glass element 1a, in particular with the outer edges of the miter.

[0048] FIG. 4 is a horizontal sectional view (B) of the corner assembly 2 according to the invention assembled at the site of use. The corner assembly 2 consists of the two insulated glass elements 1a and 1b butting against each other at an angle of 90. The corner assembly 2 represents only one possibility of the angle selection. The angle can vary to suit the site of use and have an angle size from 1 to 179.

[0049] The two insulated glass elements 1a and 1b are in each case joined to each other at their films 4 using a transparent adhesive means 6. The adhesive means 6 is preferably a silicone adhesive. The insulated glass elements 1a and 1b butt against each other in the region of their abutment ends such that the interpane spaces of the panes 1a and 1b do not merge into a continuous interpane space filled with gas. Instead, the interpane spaces with their respective gas filling remain as two separate interpane spaces still separated by the film 4.
