Abstract

A fireproof transparent pane panel is disclosed which comprises a plastic pane core disposed between panes of inorganic glass. Support elements in the form of plastic threads or strips, arranged unidirectionally or in a lattice, are embedded within the core.

Claims

1. A fireproof transparent pane panel comprising:

a plastic pane core disposed between panes of inorganic glass to form a composite pane; and

internal plastic support elements embedded within the core.

2. A pane panel according to claim 1, wherein the plastic pane core is one formed in a discontinuous casting process.

3. A pane panel according to claim 1, wherein the plastic pane core is one formed in a process of continuous coextrusion of at least two incompatible thermoplastics.

4. A pane panel according to any one of claims 1-3, wherein the plastic support elements are threads having a diameter of 1 to 5 mm, the spacing between threads does not exceed 100 mm and the density of threads per unit area is between 2.5 to 25%.

5. A pane panel according to claim 4, wherein the thickness of the plastic pane core is in the range of 4 to 40 mm.

6. A pane panel according to any one of claims 1-3, wherein the plastic support elements are monofilament threads made of at least one of polyamide and polypropylene.

7. A pane panel according to claim 4, wherein the plastic support elements are monofilament threads made of at least one of polyamide and polypropylene.

8. A pane assembly according to claim 7, wherein the thickness of the plastic pane core is in the range of 5 to 40 mm.

9. A pane panel according to any one of claims 1-3, wherein the support elements are made from a plastic having a light transmission factor of 0 to 65%.

10. A pane panel according to claim 4, wherein the support elements are made from a plastic having a light transmission factor of 0 to 65%.

11. A panel panel according to claim 5, wherein the support elements are made from a plastic having a light transmission factor of 0 to 65%.

12. A pane panel according to any one of claims 1-3, wherein the plastic pane core is an acrylic glass.

13. A pane panel according to claim 4, wherein the plastic pane core is an acrylic glass.

14. A pane panel according to claim 5, wherein the plastic pane core is an acrylic glass.

15. A pane panel according to claim 12, wherein the support elements are polyamide fibres.

16. A pane panel according to claim 13, wherein the support elements are polyamide fibres.

17. A pane panel according to claim 14 wherein the support elements are polyamide fibres.

18. A pane panel according to claim 6, wherein said threads are arranged in a lattice.

19. A pane panel according to claim 7, wherein said threads are arranged in a lattice.

20. A pane panel according to claim 8, wherein said threads are arranged in a lattice.

21. A pane panel according to claim 15, wherein said fibres are arranged in a lattice.

22. A pane panel according to claim 16, wherein said fibres are arranged in a lattice.

23. A pane panel according to claim 17, wherein said fibres are arranged in a lattice.

24. A pane panel according to any one of claims 1-3, wherein said inorganic glass panes are of different materials.

25. A pane panel according to claim 4, wherein said inorganic glass panes are of different materials.

26. A pane panel according to claim 5, wherein said inorganic glass panes are of different materials.

27. A pane panel according to claim 8, wherein said inorganic glass panes are of different materials.

28. A pane unit according to claim 9, wherein said inorganic glass panes are of different materials.

29. A pane panel according to any one of claims 1-3, wherein at least one of said inorganic glass panes is a single-pane safety glass.
