Abstract

A method can produce an assembly for a line penetration. The method includes: (a) cutting a fire-protection mat forming a fire-protection module to length appropriate for the size of the line penetration, where the fire-protection mat has a flexible carrier element, on at least one end region of which a fire-protection tape of an intumescent material is fastened, (b) bending the fire-protection mat into a circular shape and joining opposite rims of the fire-protection mat to one another via a joining means, so that the fire-protection tape is disposed in a region of an axial end of the circularly shaped fire-protection mat, and (c) fastening at least one mechanical positioning element constructed separately from the fire-protection mat on the fire-protection mat and which is arranged in such a way that the assembly can be fastened, via the mechanical positioning element, on a wall or on formwork.

First claim

The invention claimed is:

1. An assembly for a line penetration for casting in place in a building part, the assembly comprising:
at least one mechanical positioning element, which is arranged in such a way that the assembly can be fastened, via the at least one mechanical positioning element, on a wall or on formwork, and
a substantially cylindrical fire-protection module, which is provided with a flexible carrier element, on which a fire-protection tape of an intumescent material is fastened at one axial end of the fire-protection module, the fire-protection tape extending over at most 20% of an axial length of the flexible carrier element,
wherein the fire-protection module has two opposite rims, which are opposite in circumferential direction of the fire-protection module and are joined to one another via a joining means.

2. The assembly according to claim 1 , wherein
a strip element, capable of sealing against smoke gas and water, is fastened on the fire-protection tape.

3. The assembly according to claim 1 , wherein
the opposite rims of the fire-protection module fit tightly together.

4. The assembly according to claim 1 , wherein
the opposite rims of the fire-protection module are joined to one another via at least one separate joining means.

5. The assembly according to claim 4 , wherein
at least one adhesive strip is fastened to the side of the carrier element opposite the fire-protection tape.

6. The assembly according to claim 1 ,
the at least one positioning element is fastened to the side of the carrier element opposite the fire-protection tape.

7. The assembly according to claim 1 , wherein
the flexible carrier element is a foil.

8. A method for using the assembly of claim 1 for the production of a line penetration in a building part, the method comprising:
fastening the assembly via the at least one positioning element on the wall or formwork,
wherein the fire-protection module is surrounded during casting of the building part by the cast material forming the building part.

9. The assembly according to claim 1 , wherein
a strip element comprising a foam material, capable of sealing against smoke gas and water, is fastened on the fire-protection tape.

10. The assembly according to claim 1 , wherein
the opposite rims of the fire-protection module are joined to one another via at least one separate joining means that comprises a separate adhesive strip.

11. The assembly according to claim 1 , wherein the flexible carrier element is a foil, which comprises a plastic or a metal.

12. A method for producing the assembly as claimed in claim 1 for a line penetration, the method comprising:
(a) cutting a fire-protection mat forming the fire-protection module to length appropriate for the size of the line penetration, wherein the fire-protection mat has the flexible carrier element, on at least one end region of which the fire-protection tape is fastened,
(b) bending the fire-protection mat into a circular shape and joining opposite rims of the fire-protection mat to one another via the joining means, so that the fire-protection tape is disposed in a region of an axial end of the circularly shaped fire-protection mat, and
(c) fastening the at least one mechanical positioning element constructed separately from the fire-protection mat on the fire-protection mat and which is arranged in such a way that the assembly can be fastened, via the mechanical positioning element, on a wall or on formwork.

13. The method according to claim 12 , wherein
the fire-protection mat is rolled up on a core, from which it is first unrolled.

14. The method according to claim 12 , wherein
opposite rims of the fire-protection module are joined to one another via at least one separate joining means.

15. The method according to claim 12 , wherein
the at least one positioning element is fastened by a method selected from the group consisting of adhesively bonded with, plugged into, clipped onto the fire-protection module, and hooked onto the fire-protection module.

16. The method according to claim 12 , wherein
a strip element, capable of sealing against smoke gas and water, is fastened onto the fire-protection tape.

17. The method according to claim 12 , wherein the fire-protection tape is continuous.

18. The method according to claim 12 , wherein
opposite rims of the fire-protection module are joined to one another via at least one separate joining means that comprises a separate adhesive strip.

19. The method according to claim 12 , wherein
the at least one positioning element is fastened by a method selected from the group consisting of adhesively bonded with, plugged into, clipped onto the fire-protection module, and hooked onto the fire-protection module on the side of the carrier element opposite the fire-protection tape.

20. The method according to claim 12 , wherein
a strip element comprising a foam material, capable of sealing against smoke gas and water, is fastened onto the fire-protection tape.
