Abstract

A fire protection element is disclosed. The fire protection element has a foamed body formed at least partially of an ash-forming mixture, and in an embodiment, an intumescent mixture. A carrier component is embedded in the foamed body. The carrier component is a thin, flat part which is covered by the body on at least one flat side.

Claims

1. A fire protection element, comprising:

a foamed body formed at least partially of an ash-forming mixture; and

a carrier component, wherein the carrier component is comprised of a thin, flat part and wherein the carrier component is embedded in the foamed body.

2. The fire protection element according to claim 1, wherein the foamed body is additionally formed of an intumescent mixture.

3. The fire protection element according to claim 1, wherein the carrier component is completely embedded in the foamed body.

4. The fire protection element according to claim 1, wherein the carrier component is flexible.

5. The fire protection element according to claim 1, wherein the carrier component has a grid structure.

6. The fire protection element according to claim 1, wherein the carrier component is a fabric or a mat.

7. The fire protection element according to claim 6, wherein the carrier component has a mesh size, wherein threads of the fabric have a thread size, and wherein a ratio of the mesh size to the thread size is in a range of 1 to 200.

8. The fire protection element according to claim 7, wherein the threads of the fabric have a thread size which is in a range of 0.05 to 1 mm and/or the fabric has a mesh size in a range between 1 and 50 mm.

9. The fire protection element according to claim 1, wherein the carrier component is formed of a temperature-resistant material.

10. The fire protection element according to claim 9, wherein the carrier component is formed of glass fibers.

11. The fire protection element according to claim 1, wherein the carrier component is embedded in the foamed body in a bent or kinked configuration.

12. The fire protection element according to claim 10, wherein the carrier component extends to near an outer surface of the foamed body.

13. The fire protection element according to claim 1, wherein the carrier component is embedded in the foamed body in a wavy, an annular, or a U-shaped configuration.

14. The fire protection element according to claim 1, wherein the fire protection element has a shape of a rectangular solid.

15. The fire protection element according to claim 1, wherein the fire protection element is cylindrical or conical in shape.

16. The fire protection element according to claim 1, wherein the carrier component is formed into a shape.
