Abstract

A through-penetration device has a molded body consisting essentially of an intumescent foam material and having at least one penetration opening for one line. An outer contour of the molded body has protrusions extending radially outward for anchoring within a cast building component, which protrusions form undercuts in building component as the building component is being cast. In addition, a mounting plate that can be axially pushed onto the through-penetration device, sealing the penetration openings, is provided. As the through-penetration device is produced, a liquid coating material is applied to a surface of a foaming mold, and then a foam mass containing a predetermined percentage of intumescent material is introduced into the foaming mold. After a foaming process, the coating material forms a water-impermeable skin on the foamed molded body.

First claim

What is claimed is:

1. A through-penetration device, comprising:
a molded body consisting essentially of an intumescent foam material and having at least one penetration opening for a line,
wherein an outer contour of the molded body comprises a plurality of protrusions extending radially outward,
wherein the through-penetration device is configured for a cast building component,
wherein each of the protrusions is configured for being anchored within the cast building component, and
wherein an outer circumference of the molded body is surrounded by a waterproof skin.

2. The through-penetration device of claim 1 , wherein the protrusions of the plurality of protrusions are arranged behind each other in an axial direction.

3. The through-penetration device of claim 1 , wherein each of the protrusions of the plurality of protrusions is circumferentially uninterrupted.

4. The through-penetration device of claim 1 , wherein the at least one penetration opening is closed off by a membrane.

5. The through-penetration device of claim 1 , wherein the plurality of protrusions contains sufficient intumescent material to fill, in response to a fire, a cavity with a cross-sectional area corresponding to a cross-sectional area of the molded body excluding the plurality of protrusions.

6. The through-penetration device of claim 1 , further comprising a mounting plate coupled to the molded body and configured to seal the at least one penetration opening.

7. A method for producing the through-penetration device of claim 1 , the method comprising:
applying a liquid coating material to a surface of a foaming mold; and
after said applying, introducing a foam mass into the foaming mold, wherein the foam mass contains a predetermined percentage of intumescent material; and
subjecting the foam mass to a foaming process to obtain the molded body, which is a foamed molded body having a water-impermeable skin formed from the liquid coating material.

8. The method of claim 7 , further comprising casting a building component around the foamed molded body such that the plurality of protrusions extending radially outward from the foamed molded body anchor the foamed molded body in the building component.

9. The method of claim 8 , further comprising:
mounting a mounting plate on a formwork part, wherein the mounting plate comprises a plurality of protrusions matching a plurality of through-penetration openings of the foamed molded body;
setting the plurality of through-penetration openings of the foamed molded body onto the plurality protrusions of the mounting plate; and
removing the formwork part and the mounting plate after said casting the building component around the foamed molded body.

10. A through-penetration device, comprising:
a molded body consisting essentially of an intumescent foam material and having at least one penetration opening for a line,
wherein an outer contour of the molded body comprises a plurality of protrusions extending radially outward,
wherein the through-penetration device is configured for a cast building component,
wherein each of the protrusions is configured for being anchored within the cast building component, and
wherein the plurality of protrusions contains sufficient intumescent material to seal the at least one penetration opening in response to a fire.

11. The through-penetration device of claim 10 , wherein the protrusions of the plurality of protrusions are arranged behind each other in an axial direction.

12. The through-penetration device of claim 10 , wherein each of the plurality of protrusions is circumferentially uninterrupted.

13. The through-penetration device of claim 10 , wherein the at least one penetration opening is closed off by a membrane.

14. The through-penetration device of claim 10 , wherein the plurality of protrusions contains sufficient intumescent material to fill, in response to a fire, a cavity with a cross-sectional area corresponding to a cross-sectional area of the molded body excluding the plurality of protrusions.

15. The through-penetration device of claim 10 , further comprising a mounting plate coupled to the molded body and configured to seal the at least one penetration opening.

16. The through-penetration device of claim 10 , wherein an outer circumference of the molded body is surrounded by a waterproof skin.

17. A method for producing the through-penetration device of claim 10 , the method comprising:
applying a liquid coating material to a surface of a foaming mold; and
after said applying, introducing a foam mass into the foaming mold, wherein the foam mass contains a predetermined percentage of intumescent material; and
subjecting the foam mass to a foaming process to obtain the molded body, which is a foamed molded body having a water-impermeable skin formed from the liquid coating material.

18. The method of claim 17 , further comprising casting a building component around the foamed molded body such that the plurality of protrusions extending radially outward from the foamed molded body anchor the foamed molded body in the building component.

19. The method of claim 18 , further comprising:
mounting a mounting plate on a formwork part, wherein the mounting plate comprises a plurality of protrusions matching a plurality of through-penetration openings of the foamed molded body;
setting the plurality of through-penetration openings of the foamed molded body onto the plurality protrusions of the mounting plate; and
removing the formwork part and the mounting plate after said casting the building component around the foamed molded body.
