Abstract

The present invention relates to a breakage-resistant composite composed of several superposed layers, particularly as planking for a stud wall, roof or ceiling structure, wherein the composite comprises at least one first gypsum board panel in the form of a paperbound gypsum board panel, at least one metal sheet arranged on the first gypsum board panel, and at least one second gypsum board panel in the form of a gypsum fiberboard panel arranged on the metal sheet.

First claim

1 . A breakage-resistant composite composed of several superposed layers, particularly as planking for a stud wall, roof or ceiling structure, wherein the composite comprises at least one first gypsum board panel in the form of a paperbound gypsum board panel, at least one metal sheet arranged on the first gypsum board panel, and at least one second gypsum board panel in the form of a gypsum fiberboard panel arranged on the metal sheet.

2 . The breakage-resistant composite as set forth in claim 1 , wherein metal sheet and at least one second gypsum board panel are adhered to one another.

3 . The breakage-resistant composite as set forth in claim 1 , wherein at least two abreast arranged second gypsum board panels are provided, the two second gypsum board panels preferably being adhered to one another at their adjacent edge surfaces.

4 . The breakage-resistant composite, particularly as set forth in claim 1 , composed of several superposed layers, particularly as planking for a stud wall, roof or ceiling structure, wherein the composite comprises at least one first gypsum board panel, particularly in the form of a paperbound gypsum board panel, at least one metal sheet arranged on the first gypsum board panel, and at least two second gypsum board panels, particularly in the form of a gypsum fiberboard panel, arranged side-by-side and arranged on the metal sheet wherein the at least two second gypsum plaster boards are bonded onto the metal sheet and bonded with each other at adjacent edge surfaces.

5 . The breakage-resistant composite as set forth in claim 1 , wherein at least two first or second gypsum board panels form a joint between them, and at least one second gypsum board panel extends over the joint and/or at least two first or second gypsum board panels form a joint between them, and at least one other second gypsum board panel extends over the joint.

6 . The breakage-resistant composite as set forth in claim 1 , wherein the at least one first gypsum board panel has a density of preferably ≧500 kg/m 3 , more preferably ≧1,000 kg/m 3 , and/or ≦2,000 kg/m 3 , more preferably ≦1,500 kg/m 3 , and/or a thickness of ≧5 mm, preferably ≧10 mm, even more preferably (about) 12.5 mm and/or ≦40 mm, preferably ≦30 mm, even more preferably ≦20 mm.

7 . The breakage-resistant composite as set forth in claim 1 , wherein the at least one second gypsum board panel has a density of ≧800 kg/m 3 , preferably ≧1,500 kg/m 3 , and/or ≦3,000 kg/m 3 , preferably ≦2,000 kg/m 3 , and/or a thickness of 20 mm, preferably ≧28 mm and/or ≦50 mm, preferably ≦40 mm.

8 . The breakage-resistant composite as set forth in claim 1 , wherein the at least one second gypsum board panel has a higher density and/or greater thickness than the at least one first gypsum board panel.

9 . The breakage-resistant composite as set forth in claim 1 , wherein the metal sheet is a (particularly galvanized) steel sheet and/or has a thickness of ≧0.3 mm, preferably ≧0.5 mm and/or ≦1 mm, preferably ≦0.8 mm.

10 . The breakage-resistant composite as set forth in claim 1 , wherein an adhesive for adhering at least one second gypsum board panel to the at least one metal sheet is an elastic adhesive and/or an adhesive for adhering adjacent contact surfaces of two second gypsum board panels is a joint adhesive, particularly a polyurethane-based joint adhesive.

11 . A stud wall, roof or ceiling structure, comprising at least one supporting means, particularly at least one profile element, wherein at least one breakage-resistant composite as set forth in claim 1 is arranged on a first side of the supporting means, and wherein the at least one first gypsum board panel of the breakage-resistant composite faces toward the supporting means.

12 . The stud wall, roof or ceiling structure as set forth in claim 11 , wherein at least one other breakage-resistant composite is arranged on a second side of the supporting means, the at least one first gypsum board panel of the at least one other breakage-resistant composite faces toward the supporting means.

13 . (canceled)

14 . A method of safeguarding against a person's breaking in or breaking out, comprising the steps of:
a) providing a stud wall, roof or ceiling structure with at least one supporting means; and b) arranging on a first side of said supporting means at least one breakage-resistant composite.

15 . The method of claim 14 , wherein the at least one supporting means comprises at least one profile element.

16 . The method of claim 14 , wherein the at least one breakage-resistant composite includes at least one gypsum board panel, further wherein the at least one gypsum board panel faces toward the supporting means.
