  • intumescent fire protection elements which are produced in various geometric shapes or as individual moldings. These fire protection elements prepared in this way are used to seal pipe or cable feedthroughs against heat and fire, so that fire propagation in the event of a fire is delayed on an adjacent fire section. In the individual walls corresponding outbreaks are provided, are passed through the cable or pipes. The remaining after laying the pipes or cables space is then closed by the fire protection elements. The prefabricated fire protection elements are cut to size by a craftsman and used in the free space, so that the pipe and / or cable bushing at the end of the corresponding standards. The adaptation of the fire protection elements to the local conditions requires a lot of manual work and is therefore costly.
  • the present invention based on the object to provide a fire protection device, a pipe and / or cable feedthrough and a method of the type mentioned, with which a cost-effective and reliable heat and fire protection can be achieved by a pipe and / or a cable feedthrough.
  • a trained according to this technical teaching fire protection element a method carried out according to this technical teaching and trained according to this technical teaching pipe and / or Jardin ⁇ execution have the advantage that an elongated, preferably cylindrical or bar-shaped fire protection element with a length of preferably 50th cm is suitable to seal the common pipe and / or cable glands without the fire protection element needs to be cut to size on site.

  • the length to thickness ratio of the fire protection element is between 5: 1 and 15: 1, preferably 10: 1.
  • the fire protection element is axially compressible.
  • This length reduction due to the compression has the advantage that in many cases, on the one hand cutting is unnecessary, and on the other hand, more than enough material in the pipe and / or grommet is present in order to achieve sufficient heat and fire protection in case of emergency.
  • the fire protection element is local, radially compressible. This makes it possible to use this fire protection element in such free spaces in the pipe and / or grommet, which are smaller than the diameter of the fire protection element, so that an adjustment of the Fire protection element to the free space in the pipe and / or Jardin ⁇ passage by cutting away material is unnecessary. In addition, this also ensures that sufficient material is available for emergencies in the open space.
  • the fire protection element according to the invention proves to be particularly advantageous, because in this way a quick and easy insertion of the fire protection elements in the pipe and / or cable bushings is possible.
  • This fire protection element according to the invention can either be wound around the pipe and / or cable in such a way that the end faces abut one another, or come to rest with one end face on a wall, so that the other end face of the fire protection element after looping around the pipe and / or cable come to rest on an outside of the fire protection element. Both methods are quick and easy to execute.
  • the pipe and / or grommet is sufficiently closed, because the swelling in case of emergency fire protection element closes the pipe and / or cable bushing then in a sufficient manner. Consequently, the standardized fire protection element according to the invention further contributes to a simple and quick assembly.
  • fire protection elements can be used to completely wrap around the bundle of pipes and / or cables.
  • the space between the pipe and / or cable on the one hand and the wall on the other hand is so large that it can not be filled by a single fire protection element.
  • a second or third, etc., fire protection element is inserted into the wall plane, wherein the second fire protection element wraps around the first fire protection element.

  • FIG. 2 is a perspective view of a second embodiment of a fire protection element according to the invention
  • FIG. 3 shows a side view of a first embodiment of a cable feedthrough according to the invention
  • FIG. 4 shows a side view of a second embodiment of a cable feedthrough according to the invention.
  • FIG. 5 shows a side view of a third embodiment of a cable feedthrough according to the invention.
  • FIG. 6 shows a side view of a fourth embodiment of a cable feedthrough according to the invention.

  • FIG. 7b is a side view, cut in section, of the cable duct according to FIG. 7a at a second time.
  • FIG. 1 shows a first embodiment of a fire protection element according to the invention.
  • This fire protection element 10 is cylindrical and has a length of 50 cm with a diameter of 5 cm.
  • This fire protection element 10 is made of an intumescent forming foaming foam which foams at high heat and multiplies its volume without burning. This fire protection element deforms, but remains a coherent component and isolated to a great extent.
  • This dimensionally deformable fire protection element 10 can be pressed locally in the radial direction or compressed in the axial direction without damaging it. After completion of this radial or axial force, the fire protection element forms back to its original, cylindrical shape. It is understood that, for example, with an axial compression of the diameter of the fire protection element 10 at the point in question increases slightly. Analogous applies to radial impressions. Nevertheless, the fire protection element 10 remains substantially cylindrical. This fire protection element 10 is also flexible and strong bendable so that it can be wrapped around pipes or cables.
  • FIG. 2 shows a second embodiment of a fire protection element according to the invention.
  • This fire protection element 12 differs from the fire protection element 10 shown in Fig. 1 only in that it has no round but a square cross-section.
  • the fire protection element may also have a different cross section, for example, an oval, semi-circular, triangular, pentagonal, hexagonal or the like cross-section. It is also conceivable to form the fire protection element profiled.

  • a free space 22 is provided in a corner of a wall 16 near a side wall 18 and a ceiling 20, through which a cable 24 is laid.
  • this clearance 22 In order to prevent fire or heat from passing through the free space 22 necessary for the laying of the cable 24 in the event of an emergency, this clearance 22 must be closed in accordance with the fire protection regulations.
  • the standardized Brandschutz ⁇ element 10 is wrapped around the cable 24 so that the fire protection element 10, the cable 24 almost completely encloses.

  • the fire protection element is laid transversely to the direction of the cable 24.
  • the fire protection element 10 deformed when inserted into the free space 22. That is, the fire protection element 10 is pressed radially gallery ⁇ in some places and compressed in total axially.
  • the fire protection element 10 adapts to the local conditions of the free space 22, without any work having to be carried out on the fire protection element 10. It is not problematic that the space 22 is not completely accessible ⁇ fills the fire protection element 10, as long as the remaining remaining spaces are so small that they are filled in the event of fire from the foaming fire protection element 10.
  • the fire protection element 10 can be wrapped around the cable 24 and in the Free space 22 are inserted. Consequently, the standardized fire protection element 10 enables fast, simple and cost-effective installation.
