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.

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.
