Abstract

The invention relates to a method for providing a fire safe penetration in a building element, especially in a ceiling, floor or in a lightweight wall comprising a framework of profile elements and at least one outer covering being fixed to said profile elements. For providing a fire safe penetration in a building element, for example a lightweight building wall, in such a manner that the building element or insert can be easily manufactured and installed while guaranteeing the high requirements of flame and smoke resistance of such a building element or the insert, the invention proposes the following consecutive steps:

• • arranging an insert between the profile elements at a location for a pipe or conduit penetration in a way that the insert is arranged adjacently to the outer covering and is at least partly covered by the outer covering;
  • providing an opening in the outer covering and the insert for a pipe or conduit;
  • arranging the pipe or conduit through the outer covering and the insert and
  • securing fire and/or smoke tightness between the pipe or conduit and the insert and/or outer covering.

Claims

1. A method for providing a fire safe pipe penetration in a building element, especially in a ceiling, a floor or in a lightweight building wall comprising a framework of profile elements and at least one outer covering, being fixed to said profile elements, said method comprising the following consecutive steps:

arranging an insert between the profile elements at a location for a pipe or conduit penetration in a way that the insert is arranged adjacently to the outer covering and is at least partly covered by the outer covering;

providing an opening in the outer covering and the insert for a pipe or conduit;

arranging the pipe or conduit through the outer covering and the insert and securing fire and/or smoke tightness between the pipe or conduit and the insert and/or outer covering.

2. The method according to claim 1, wherein said insert for receiving and guiding energy conduits and/or conduits for carrying liquids or gases and having two large surfaces being arranged between said profile elements comprises at least one rigid plate which is made of a heat and/or sound insulation material and which is noncombustible according to class A2.

3. The method according to claim 1, wherein said plate consists of artificial resin-bound mineral fibers and has a bulk density of at least 150 kg/m³.

4. The method according to claim 1, wherein two large surfaces of said insert are oriented in a plane parallel to said outer covering, wherein side faces of the insert are oriented at right angles to said large surfaces.

5. The method according to claim 2, wherein said plate includes on at least two mutually parallel extending side faces a respective cover which is preferably made up from rigid profiles and serves for fixing said plate to said building element.

6. The method according to claim 1, wherein said insert is designed in a sandwich-like fashion and includes in addition to the plate at least one layer of a plasterboard plate or a cement-bound construction material.

7. The method according to claim 1, wherein said insert has edge lengths of 610 mm to 635 mm, in particular 625 mm, and 305 mm to 315.25 mm, in particular 312.5 mm.

8. The method according to claim 1, wherein said insert is laminated with a flat metal element, in particular with an aluminum foil.

9. The method according to claim 1, wherein said insert is screwed together with at least one profile element.

10. The method according to claim 1, wherein said building element is a lightweight building wall and wherein said insert in the region of its two side faces which extend perpendicularly in the installed position is designed with two L-shaped fixing elements having two legs which are oriented at right angles to each other, one of these legs being connected to said insert and the second leg being connected to the floor or the ceiling of the building, particularly by screwing.

11. The method according to claim 2, wherein said plate consists of artificial resin-bound mineral fibers and has a bulk density of at least 150 kg/m³.

12. The method according to claim 2, wherein two large surfaces of said insert are oriented in a plane parallel to said outer covering, wherein side faces of the insert are oriented at right angles to said large surfaces.

13. The method according to claim 3, wherein two large surfaces of said insert are oriented in a plane parallel to said outer covering, wherein side faces of the insert are oriented at right angles to said large surfaces.

14. The method according to claim 2, wherein said plate includes on at least two mutually parallel extending side faces a respective cover which is preferably made up from rigid profiles and serves for fixing said plate to said building element.

15. The method according to claim 3, wherein said insert is designed in a sandwich-like fashion and includes in addition to the plate at least one layer of a plasterboard plate or a cement-bound construction material.

16. The method according to claim 2, wherein said insert is laminated with a flat metal element, in particular with an aluminum foil.

17. The method claim 2, wherein said building element is a lightweight building wall and wherein said insert in the region of its two side faces which extend perpendicularly in the installed position is designed with two L-shaped fixing elements having two legs which are oriented at right angles to each other, one of these legs being connected to said insert and the second leg being connected to the floor or the ceiling of the building, particularly by screwing.

18. The method claim 3, wherein said building element is a lightweight building wall and wherein said insert in the region of its two side faces which extend perpendicularly in the installed position is designed with two L-shaped fixing elements having two legs which are oriented at right angles to each other, one of these legs being connected to said insert and the second leg being connected to the floor or the ceiling of the building, particularly by screwing.

19. The method according to claim 3, wherein said plate consists of artificial resin-bound mineral fibers and has a bulk density of at least 150 kg/m³.

20. The method according to claim 19, wherein said insert is laminated with a flat metal element, in particular with an aluminum foil.
