Fire protection apparatus
View Patent ↗A fire protection device is for a cable bushing that leads a cable unit from a fire-risk area to an area to be protected against fire. The fire protection device has a fire protector that is provided for protection against the spread of fire into the space to be protected through the cable bushing. The fire protector is configured as an assembly component.
1. A fire protection apparatus for a cable interface of a separating apparatus for separating a space at risk of fire from a space to be protected from the fire, the cable interface having an opening being cut out in the separating apparatus and a cable bushing leading a cable unit from the space at risk of fire to the space to be protected against fire, the fire protection apparatus comprising:
a fire protection device for protecting against a spread of the fire into the space to be protected through the cable bushing, said fire protection device having a structural unit made of an intumescent material and a main body, said structural unit fastened to said main body, said fire protection device together with the cable bushing forming a cable duct for the cable unit and said fire protection device being a prefabricated assembly component which is mountable in a region of the cable interface, wherein a mounting of the prefabricated assembly component in the region of the cable interface includes coupling the prefabricated assembly component to the cable bushing.
2. The fire protection apparatus according to claim 1 , wherein when said fire protection device is coupled to the cable bushing, said fire protection device and the cable bushing overlap in a direction oriented perpendicular to a direction of extent of the cable unit.
3. The fire protection apparatus according to claim 1 , wherein when said structural unit is installed, the cable unit runs through said structural unit.
4. The fire protection apparatus according to claim 1 , wherein said main body is a hollow body having an inner space provided for a passage of the cable unit and in said inner space said structural unit is disposed.
5. The fire protection apparatus according to claim 1 , wherein said fire protection device has an annular form.
6. The fire protection apparatus according to claim 1 , wherein said fire protection device has at least two partial regions and at least one coupling point, at said coupling point said at least two partial regions are coupled to one another when said fire protection device is assembled around the cable unit in a laid state of the cable unit.
