Definitions

  • the invention relates to a fire protection element for sealing off openings passing through walls or ceilings, in particular of line passages, with a molded part of intumescent material.
  • Fire protection elements that can close cable ducts with non-refractory pipes or cables in ceilings or walls in case of fire to prevent the spread of fire and smoke in buildings, are known in various designs.
  • the fire protection elements typically include an intumescent material with expanded graphite disposed about the leads and a reinforcing insert that stabilizes the intumescent material.
  • the expandable graphite particles are activated by the heat at the surface, expand towards the fire and initially form an insulating crust.
  • it becomes unstable after some time and falls off.
  • the crust is no longer available as an insulating layer, and the underlying intumescent layer is activated.
  • the fire protection element burns off step by step and ensures protection only for a limited duration.
  • the object of the invention is to provide a fire protection element, which forms a more stable crust in the event of fire and which makes it easier to install cables ordered.
  • a fire protection element for sealing off openings passing through walls or ceilings, in particular of line passages, with a molded part made of intumescent material.
  • the molded part has a plurality of passage openings for the passage of lines, which extend in particular parallel to each other from a first side to an opposite second side of the fire protection element and are each sealed by a gas-tight sealing membrane.
  • the several Through openings in the fire protection element allow a simple way, different types of lines separated from each other by the fire protection element to lead, for example, by electricity and data cables occupy their own through holes. In this way, the fire protection element can be used as a cable management system.
  • the membrane ensures that unoccupied through-holes are smoke gas tight.
  • the membrane In order to guide a line through a passage opening, the membrane is pierced in the corresponding passage opening. It may be provided a single membrane which closes all passage openings, for example by the membrane extends substantially through the entire molded part. Alternatively, it is also possible to provide a plurality of membranes, each of which closes only a part of the through-openings or only individual through-openings.
  • the molding preferably has a honeycomb structure.
  • a honeycomb structure is a three-dimensional grid which is constructed in a sectional plane from one or more basic shapes in the form of polygons and extends along an axis which is in particular perpendicular to the sectional plane.
  • the honeycomb structure has a uniform, hexagonal basic shape and thus forms a kind of honeycomb or honeycomb.
  • the advantage of the fire protection element according to the invention is that due to the lattice-shaped honeycomb structure, the intumescent material can expand into the honeycomb and can there connect with intumescent material of adjacent honeycomb structures. This creates a networked, stable crust in case of fire, which ensures reliable fire protection for a longer period.
  • the membrane is located midway between the first and second sides and preferably runs parallel to one of these sides.
  • the membrane separates the passage opening into two sections, which have the same depth perpendicular to the first or second side.
  • the fire protection element can be constructed symmetrically with respect to the membrane, whereby the fire protection element has the same properties on both sides of the membrane.
  • At least part of the passage openings can be filled with a filling foam.
  • the filling foam ensures a smoke-tight closure of the passage opening which has been pierced by a line in that the passage opening, in particular completely, is filled with the filling foam.
  • the filling foam is used for storage of the pipes and the sound insulation.
  • the fire protection element has a frame which surrounds the molded part in a circumferential direction at least in sections, in particular wherein the circumferential direction extends around an axis which is arranged parallel to the axial extent of the through holes.
  • the first and the second side of the molding are not covered by the frame.
  • the frame is preferably in one piece. This offers the advantage that there are only a few transition areas between different sections of the frame, in which intumescent material and / or filling material can escape in case of fire. In this way, the frame limits the propagation of the intumescent material in the event of fire and thus makes it possible to direct the expansion of the intumescent material in a desired direction. Thus, since the intumescent material no longer propagates uncontrollably in all directions, the amount of intumescent material in the fire protection element can be reduced, resulting in lower manufacturing costs. Further, different portions of the frame stabilize each other in the expansion of the intumescent material, so that the structural integrity of the fire protection element is improved by this design.
  • the frame comprises a material from the following group: cardboard, metal, glass fibers, basalt fibers, carbon fibers, or ceramic fibers.
  • a hybrid structure of the frame of several materials is possible. These materials show in comparison to intumescent material of the molding on a higher temperature resistance. This is advantageous because the frame is not affected by the temperature activating the intumescent material and can thus exert its stabilizing function even in case of fire.
  • the frame comprises a metal sheet, an expanded metal, a mineral structural panel, a fiberglass screen or mesh.
  • the use of a fabric provides a good connection of the frame with the molding.
  • a fabric frame retains its stabilizing properties even with isolated structural damage.
  • the frame may comprise an intumescent material, wherein the intumescent material may be identical to the intumescent material of the honeycomb structure.
  • the frame expands in case of fire in addition to the intumescent material of the honeycomb structure and ensures a tight closure of the opening and secure storage of the fire protection element in the opening.
  • the fire protection element has a cover plate to protect the molded part.
  • the cover plate is in particular intended to cover the first or the second side of the fire protection element, which are outside, i. potentially facing the fire. It is advantageous if the cover plate substantially completely covers one side of the molded part. It can also be provided several cover plates, in particular one on the first and one on the second side.
  • the cover plate preferably comprises a material from the following group: cardboard, metal, glass fibers, basalt fibers, carbon fibers or ceramic fibers.
  • a hybrid construction of the cover plate of several materials is possible. These materials have a high temperature resistance compared to the intumescent material of the molded part and improve the fire protection properties of the fire protection element.
  • the cover plate comprises a metal sheet, an expanded metal, a mineral building board, a fiberglass grid or fabric.
  • a fabric has the advantage that lines are more easily passed through the cover plate can be. Further, a fabric cover plate maintains its structural integrity even with isolated damage.
  • the cover plate may have an intumescent material.
  • the cover plate is an additional intumescent layer, which improves the fire protection properties of the fire protection element.
  • the molded part has expandable graphite.
  • the intumescent material which forms the walls of the through-openings, contains expandable graphite as an essential constituent, in the event of fire branches of expandable graphite particles form in the passage openings, which interlock with other branches of expandable graphite particles from opposite walls and form clusters.
  • the molding is preferably cuboid or cylindrical, in particular circular cylindrical. Alternatively, the molding may be a prism.
  • the fire protection element has substantially the same shape. This design has the advantage that the fire protection element is particularly suitable for sealing off rectangular or round openings, which occur most frequently in practice. Furthermore, molded parts in these forms are inexpensive to produce and can be stored space efficient.
