Abstract

A transparent, burglary-resistant fire protection glazing includes at least one centrally arranged, burglary-resistant composite that includes at least one transparent plastic pane, at least two fire protection units arranged on both sides of the centrally arranged, burglary-resistant composite, and two outer surfaces opposite one another.

First claim

The invention claimed is:

1. A transparent, burglary-resistant fire protection glazing, comprising
one centrally arranged, burglary-resistant composite that includes two plastic planes that are connected by one adhesion-promoting layer,
two fire protection units each arranged on a respective side of the centrally arranged, burglary-resistant composite, wherein each of the fire protection units includes three glass panes, wherein adjacent glass panes of each fire protection unit are adhesively bonded by a transparent, intumescent layer,
two glass panes each arranged on a respective side of the centrally arranged, burglary-resistant composite, wherein each glass pane is arranged between the burglary-resistant composite and a respective fire protection unit and is immediately adjacently connected to the burglary-resistant composite via one adhesion-promoting layer; and
wherein two outermost surfaces of the transparent, burglary-resistant fire protection glazing, opposite one another, are formed by the fire protection units.

2. The transparent, burglary-resistant fire protection glazing according to claim 1 , wherein each of the transparent plastic panes of the burglary-resistant composite is made of polycarbonate or polymethyl methacrylate.

3. The transparent, burglary-resistant fire protection glazing according to claim 1 , wherein a thickness of the burglary-resistant composite is at least 1 mm.

4. The transparent, burglary-resistant fire protection glazing according to claim 1 , wherein a glass pane that is immediately adjacently connected to the plastic panes by adhesion-promoting layers is arranged between the two plastic panes.

5. The transparent, burglary-resistant fire protection glazing according to claim 1 , wherein the adhesion-promoting layers are films made of polyvinyl butyral or polyurethane.

6. The transparent, burglary-resistant fire protection glazing according to claim 1 , wherein the intumescent layers are made of alkali silicates and/or salt-filled aqueous acrylic polymers.

7. The transparent, burglary-resistant fire protection glazing according to claim 1 , wherein the glass panes are made of soda lime glass.

8. The transparent, burglary-resistant fire protection glazing according to claim 1 , which is UV-protected.

9. An antipanic door, including a fire protection glazing according to claim 1 arranged in a frame system and a one-sided opening mechanism that is arranged to open the antipanic door at any time in one direction.

10. A method for producing a transparent, burglary-resistant fire protection glazing according to claim 1 , comprising constructing a laminate composite by precisely superimposing individual planar pane elements and introducing the pane elements into an autoclave furnace and adhesively bonding them at elevated temperature and pressure.

11. A method comprising utilizing a transparent, burglary-resistant fire protection glazing according to claim 1 as an architectural construction element.

12. A method comprising forming an antipanic glazing with the transparent, burglary-resistant fire protection glazing according to claim 1 .

13. The transparent, burglary-resistant fire protection glazing according to claim 3 , wherein the thickness of the burglary-resistant composite is from 1 mm to 15 mm.

14. The transparent, burglary-resistant fire protection glazing according to claim 13 , wherein the thickness of the burglary-resistant composite is from 2 mm to 15 mm.

15. The transparent, burglary-resistant fire protection glazing according to claim 14 , wherein the thickness of the burglary-resistant composite is from 6 mm to 12 mm.

16. The method according to claim 11 , wherein the transparent, burglary-resistant fire protection glazing forms a glass door or a stationary glazing.

17. The method according to claim 11 , wherein the transparent, burglary-resistant fire protection glazing is arranged in a museum, a bank, in an airport, a terminal, or a railway station.

18. The transparent, burglary-resistant fire protection glazing according to claim 1 , wherein a same number of glass panes is arranged on the respective side of the centrally arranged, burglary-resistant composite.
