Abstract

A walk-on laminated safety glass pane having an anti-slip surface is described. The laminated safety glass pane includes at least two glass panes, which are permanently bonded to each other using a polymeric layer.

A polymeric intermediate layer is applied to one surface of the laminated safety glass pane.

A glass pane having an anti-slip surface is applied to the polymeric intermediate layer.

An elastic polymeric gasket is inserted circumferentially in the edge region of the polymeric intermediate layer.

The laminated safety glass pane has a drilled hole and the drilled hole is sealed at subatmospheric pressure.

Claims

1. A walk-on laminated safety glass pane having an anti-slip surface, comprising:

a first glass pane and a second glass pane that are permanently bonded to each other through a polymeric layer to form a laminated safety glass pane;

a polymeric intermediate layer applied to one surface of the laminated safety glass pane;

a third glass pane having an anti-slip surface, the third glass pane being applied to the polymeric intermediate layer; and

an elastic polymeric gasket inserted circumferentially in an edge region of the polymeric intermediate layer,

wherein the laminated safety glass pane has a drilled hole sealed at subatmospheric pressure with a valve within the drilled hole.

2. The walk-on laminated safety glass pane according to claim 1, wherein the polymeric layer contains at least one of the polymeric films polyvinyl butyral (PVB), ethyl vinyl acetate (EVA), and polyurethane (PU) with a thickness of 0.76 mm to 1.6 mm.

3. The walk-on laminated safety glass pane according to claim 1, wherein the first glass pane and the second glass pane each have a thickness of 8 mm to 25 mm.

4. The walk-on laminated safety glass pane according to claim 1, wherein the polymeric intermediate layer contains at least one of the polymeric films polyvinyl butyral (PVB), ethyl vinyl acetate (EVA), polyurethane (PU), and polyvinyl chloride (PVC) with a thickness of 0.5 mm to 2.0 mm.

5. The walk-on laminated safety glass pane according to claim 1, wherein the polymeric intermediate layer is located under the anti-slip surface in an at least partial longitudinal correspondence with the anti-slip surface.

6. The walk-on laminated safety glass pane according to claim 5, wherein the polymeric intermediate layer is in full longitudinal correspondence with the anti-slip surface.

7. The walk-on laminated safety glass pane according to claim 1, wherein the third glass pane is thermally or chemically prestressed or partially prestressed and has a thickness of 6.0 mm to 12.0 mm.

8. The walk-on laminated safety glass pane according to claim 1, wherein the anti-slip surface is a surface coating applied to the third glass pane.

9. The walk-on laminated safety glass pane according to claim 8, wherein the surface coating covers the third glass pane at least in regions of the third glass pane.

10. The walk-on laminated safety glass pane according to claim 8, wherein the surface coating forms a predetermined pattern of the third glass pane.

11. The walk-on laminated safety glass pane according to claim 1, wherein the circumferential elastic polymeric contains one or more of silicone rubber, polyurethanes, butyl rubber, and polyacrylates.

12. The walk-on laminated safety glass pane according to claim 1, wherein the elastic polymeric gasket is a silicone profile.

13. The walk-on laminated safety glass pane according to claim 1, wherein the elastic polymeric gasket has protrusions.

14. The walk-on laminated safety glass pane according to claim 1, wherein the drilled hole has a diameter of 5 mm to 8 mm.

15. An arrangement comprising the walk-on laminated glass safety pane of claim 1, the arrangement being selected from the group consisting of:

a glass floor, a platform, a stair step, a light cutout, and a bridge glazing.

16. A method for producing a walk-on laminated safety glass pane, comprising:

providing a first glass pane and a second glass pane that are permanently bonded to each other through a polymeric layer to form a laminated safety glass pane, wherein the laminated safety glass pane has a drilled hole;

applying a polymeric intermediate layer to one surface of the laminated safety glass pane;

placing a circumferential elastic polymeric gasket in an edge region of the polymeric intermediate layer;

placing a third glass pane having an anti-slip surface on the polymeric intermediate layer so as to fit into the circumferential elastic polymeric gasket;

applying subatmospheric pressure through the drilled hole in the laminated safety glass pane; and

sealing the drilled hole at subatmospheric pressure with a valve within the drilled hole.
