Abstract

A fire protection element for a smoke-gas-proof and fire-resistant bulkheading of line lead-throughs is disclosed. The fire protection element has at least one flat molded body made of an elastically deformable material, which is made at least partially of an ash-forming and, if applicable, intumescent mixture, where at least one surface of the molded body is structured. The structured surface is formed by projecting elements that are arranged regularly or irregularly, which may be configured to be punctiform or linear. Such a fire protection element makes it possible to seal a component through-hole so that it is smoke-gas-proof and fire-resistant in the case of subsequent occupation by a line such as a cable or a pipe.

Claims

1. A fire protection element for a smoke-gas-proof and fire-resistant bulkheading of a line lead-through, comprising:

a flat molded body of an elastically deformable material with a structured surface.

2. The fire protection element according to claim 1, wherein the flat molded body has a rectangular block shape and wherein the structured surface is a top surface of a base of the flat molded body.

3. The fire protection element according to claim 2, wherein the structured surface includes projecting elements that are arranged regularly or irregularly.

4. The fire protection element according to claim 3, wherein the projecting elements have different or similar geometries and/or dimensions.

5. The fire protection element according to claim 3, wherein the projecting elements are pyramidal, conical, hemispherical, or nubby.

6. The fire protection element according to claim 2, wherein the structured surface includes projecting elements and wherein the projecting elements are arranged intermittently along lines of the structured surface.

7. The fire protection element according to claim 1, wherein the structured surface includes elevations and depressions and wherein the elevations and depressions form grooves.

8. The fire protection element according to claim 7, wherein the grooves are undulated, trapezoidal, or wedge-shaped in a direction of a thickness of the fire protection element.

9. The fire protection element according to claim 7, wherein the grooves are rectilinear, undulated, trapezoidal, or wedge-shaped in a direction of a plane of the fire protection element.

10. The fire protection element according to claim 7, wherein the elevations have a same or a different height.

11. The fire protection element according to claim 10, wherein the height is different in an alternating or irregular manner.

12. The fire protection element according to claim 1, wherein the molded body is made of a foamable binding agent which contains an ash-forming and intumescent mixture.

13. The fire protection element according to claim 1, wherein the molded body includes a carrier element.

14. The fire protection element according to claim 1, further comprising a second flat molded body of an elastically deformable material with a second structured surface, wherein the structured surface of the flat molded body faces the second structured surface of the second flat molded body.

15. The fire protection element according to claim 14, wherein the structured surface of the flat molded body and the second structured surface of the second flat molded body are complementary.

16. The fire protection element according to claim 1, wherein the flat molded body is made at least partially of an ash-forming and intumescent mixture.

17. A method for sealing a lead-through of a component, comprising the steps of:

disposing a fire protection element in the lead-through of the component, wherein the fire protection element is a flat molded body of an elastically deformable material with a structured surface.

18. A device for receiving a line in a lead-through of a component, comprising:

a jacket-like housing with a sealing insert, wherein the sealing insert is a flat molded body of an elastically deformable material with a structured surface.

19. The device according to claim 18, wherein the structured surface includes a projecting element that projects into a receiving area of the sealing insert.

20. The device according to claim 18, wherein the structured surface includes elevations and depressions which are complementary.
