Abstract

In the case of a structural glass element with a plastic-coated glass panel and at least one assembly element attached hereon, the glass panel is coated in particular with a silicone-based elastomer across its entire surface, and the coating at the same time creates an adhesive joint with one section of the assembly element supported on the glass panel.

First claim

The invention claimed is:

1. A structural glass element comprising a glass panel and at least one mounting element attached thereon,
wherein the glass panel is coated on its entire surface with a silicone-based elastomer coating, and the silicone-based elastomer coating at the same time creates an adhesive joint with a section of the at least one mounting element supported on the glass panel,
wherein the at least one mounting element comprises a metal sheet that is bent on at least one of its edges to define a mounting bracket projecting upright at an end of the metal sheet from a supported section of the metal sheet that is adhered over the surface of the glass panel, the mounting bracket being configured to be used to assemble the structural glass element, wherein the mounting element is floating on or impressed in the silicone-based elastomer coating, and
wherein a starting material for the silicone-based elastomer coating is a condensation cross-linkable silicone composition comprising:
a component A comprising:
at least one hydroxyl group terminated polydiorganosiloxane P; and

a component B comprising:
at least one cross-linking agent for polydiorganosiloxanes, and
at least one catalyst for the cross-linking of polydiorganosiloxanes.

2. The structural glass element according to claim 1 , wherein the supported section of one or each mounting element is formed by a perforated metal sheet, the holes of which are penetrated at least partially by the silicone-based elastomer coating of the glass panel.

3. The structural glass element according to claim 1 , wherein the surface of the glass panel is covered by more than a quarter, with the supported section of the mounting element or the supported sections of multiple mounting elements.

4. The structural glass element according to claim 1 , wherein the silicone-based elastomer coating has a thickness in the range between 1 and 7 mm.

5. The structural glass element according to claim 1 , wherein the silicone-based elastomer coating is densely pigmented such that the structural glass element is non-transparent in the visible range and the silicone-based elastomer coating covers the mounting element.

6. The structural glass element according to claim 1 , wherein the two-component silicone composition in addition comprises at least one color paste or one color pigment.

7. The structural glass element according to claim 1 , further comprising more than one assembly element.

8. The structural glass element according to claim 1 , wherein the silicone-based elastomer coating has a thickness in the range between 2 and 5 mm.

9. A method for producing a structural glass element according to claim 1 , wherein a starting material of the coating is poured or sprayed onto the glass panel in the liquid condition, such that a level surface is formed by flowing.

10. A method for producing a structural glass element according to claim 1 , wherein a starting material of the coating is wiped onto the glass panel with a doctor blade in the liquid or pasty condition.

11. A method for producing a structural glass element according to claim 1 , wherein a starting material of the coating is rolled onto the glass panel in the pasty condition, wherein in particular a plastic film is inserted between the surface of the starting material and the surface of the coating roller, which is pulled-off again after the application and prior to the curing of the coating.

12. The method according to claim 9 , wherein the liquid or pasty condition of the starting material will at least be adjusted among other things by adjusting a preliminary reaction time prior to the application onto the glass panel.
