Abstract

Firewall that is used in an area of a fire compartment to prevent fire from skipping to other areas, whereby the fire wall is comprised of modularly constructed sub-elements which are essentially composed of profiles assembled to form a surrounding frame that simultaneously separate two glass panes, whereby the glass panes extend to the outer edge of the profiles, and the frame is covered by a partial enameling of the glass panes, and the sub-elements can be connected to each other by connecting elements with the interposition of fireproof laminates.

Claims

1. A firewall that is used in an area of a fire compartment to prevent fire from skipping to other areas, characterized by the fact that the fire wall consists of modularly constructed sub-elements (1, 2), which are essentially composed of profiles (5) assembled to form a surrounding frame that simultaneously separate two glass panes (3, 4), whereby the glass panes (3, 4) extend to the outer edge of the profiles, and the frame is covered by a partial enameling (19) of the glass panes, and the Sub-elements (1, 2) can be connected to each other by connecting elements (9) with the interposition of fireproof laminates (15).

2. The fire wall as claimed in

claim 1

, characterized by the fact that there is a transparent fireproofing agent between the separated glass panes (3, 4).

3. The fire wall as claimed in

claim 1

, characterized by the fact that the profile (5) has at least one cavity (8), whereby the cavity (a) has an opening or depression that is suitable for the connection or additional profiles or for the use of the connecting elements (22).

4. The fire wall as claimed in

claim 2

, characterized by the fact that the profile (5) has projections (20) on each side that cover some or all of the edges (6) of the glass panes (3, 4).

5. The fire wall as claimed in

claim 4

, characterized by the fact that the glass panes (3, 4), in the vicinity of the edges (6), have recesses (6) that are occupied by legs (13) of an edge profile (12).

6. The fire wall as claimed in

claim 4

, characterized by the fact that the glass panes (3, 4) have beveled edges in the vicinity of the edges (6) of the glass panes, which beveled edges are covered by the edge profile (12).

7. The fire wall as claimed in

claim 6

, characterized by the fact that an outer contour (21) of the edge profile (12) is interrupted on each side by a T-groove (10).

8. The fire wall as claimed in

claim 7

, characterized by the fact that a seal (11) is inserted in the T-groove (10).

9. The fire wall as claimed in

claim 8

, characterized by the fact that at least one fireproof laminate (15) is integrated in the outer contour (21).

10. The fire wall as claimed in

claim 9

, characterized by the fact that the edge profile (12) can be connected in the profile (5).

11. The fire wall as claimed in

claim 10

, characterized by the fact that the connecting element (22) is a rod-shaped component, with a rotation mechanism (16) located in the middle, whereby hook elements (9) are positively and non-positively attached to each end.

12. The fire wall as claimed in

claim 11

, characterized by the fact that the rotation mechanism (16) has a square nut or a hex nut.

13. The fire wall as claimed in

claim 11

, characterized by the fact that the rotation mechanism (16) is formed by borings in the rod (18).

14. The fire wall as claimed in

claim 11

, characterized by the fact that the hook elements (22) are engaged through the opening in the profile (5), and can be fixed in position in the sub-elements (1, 2) by the rotation of the connecting elements and simultaneously connect the sub-elements (1, 2) with each other.

15. The fire wall as claimed in

claim 14

, characterized by the fact that the profile (9) and the edge profile (12) are made of plastic, steel, wood or light alloy.

16. The fire wall as claimed in

claim 15

, characterized by the fact that the plastic is a fiberglass-reinforced plastic.

17. The fire wall as claimed in

claim 1

, characterized by the fact that a fire door is installed in the fire wall.

18. The fire wall as claimed in

claim 17

, characterized by the fact that the fire door is a single-panel or double-panel side-hung door.

19. The fire wall as claimed in

claim 17

, characterized by the fact that the fire door is a single-panel or double-panel swinging door;

and the glass panes (3, 4) are made of a safety glass.

20. The fire wall as claimed in

claim 2

, characterized by the fact that the fireproofing agent is a fireproofing gel or a fireproof glass;

the glass panes (3, 4) are replaced by non-tranparent sheet materials; and

the material consists of plastic, wood, steel or light alloy.
