Abstract

A fire protection element is useful for the separation of openings passing through walls or ceilings, in particular of line passages. The fire protection element has a core consisting of a filling material and a frame. The frame surrounds the core at least in some sections in a circumferential direction and is fixedly connected to the core. Furthermore, the frame is made from an intumescent material and has a reinforcing element.

First claim

1 . A fire-protection element for sealing of openings, that are routed through walls or ceilings, comprising:
a core of filling material, and a frame, wherein the frame surrounds the core at least in portions in a peripheral direction and is joined securely to the core, wherein the frame is formed from an intumescent material and is provided with at least one reinforcing element.

2 . The fire-protection element according to claim 1 , wherein the filling material contains substantially no fire-protection additives.

3 . The fire-protection element according to claim 1 , wherein the filling material is a soft foam.

4 . The fire-protection element according to claim 1 , wherein the intumescent material is a hard foam.

5 . The fire-protection element according to claim 1 , wherein the frame has an intumescent volume that is provided for sealing, in a fire, a cross section formed by the frame.

6 . The fire-protection element according to claim 1 , wherein the reinforcing element is disposed in the peripheral direction in an outer surface of the frame.

7 . The fire-protection element according to claim 1 , wherein the reinforcing element is formed by a panel, a mat, a mesh or a fabric, or combinations thereof.

8 . The fire-protection element according to claim 1 , wherein two opposite sides of the core are substantially not covered by the frame.

9 . The fire-protection element according to claim 1 , wherein the frame has an abutting edge formed by a first end and an opposite second end of the frame.

10 . The fire-protection element according to claim 1 , wherein the fire-protection element is substantially rectangular.

11 . The fire-protection element according to claim 4 , wherein the hard foam has a density of 100 kg/m 3 to 600 kg/m 3 .

12 . The fire-protection element according to claim 7 , wherein the reinforcing element comprises at least one material selected from the group consisting of metal, expanded metal, glass fibers, basalt fibers, carbon fibers and ceramic fibers.

13 . The fire-protection element according to claim 10 , wherein the fire-protection element has a substantially rectangular core.

14 . The fire-protection element according to claim 1 , wherein the frame consists of a single piece.

15 . The fire-protection element according to claim 3 , wherein the soft foam is elastic.
