Definitions

  • the invention relates to a fire protection system having a receiving body with a cavity and arranged therein fire protection plate of inorganic porous material, especially mineral wool, and with a fire retardant, which foams under heat, wherein the fire retardant is applied to the surface side of the fire protection plate and / or in the cavity of the receiving body , and wherein the fire retardant is arranged there only in partial areas.
  • the invention relates to a fire door according to claim 10, a fire wall element according to claim 12 and a fire protection plate according to the preamble of claim 14th
  • Such fire protection systems are used to effectively prevent the spread of a fire. They have fire protection panels, which are mostly used as a deposit for fire doors or gates, and also in non-movable building parts such. Wall elements etc. can be inserted.
  • the fire resistance of a fire protection system is determined by the length of time at which, at a certain temperature rise on one side of the fire protection system, such as a fire door, the other "cold" side of the fire protection system remains below a defined limit temperature.
  • the period of time in minutes until reaching the limit temperature on the cold side is referred to as the service life and, according to DIN 4102 Part 5 or DIN-EN 1634-1, the classification into the various fire resistance classes.
  • a rating in the F30 fire rating means a 30-minute life while F90 indicates a 90-minute life.
  • Such a fire protection plate is for example from the EP 2 236 282 A1 known.
  • the fire protection agent is arranged inside the fire protection board. It is present in nests, which are arranged in at least one thickness range of the fire protection board. In this case, their distance and / or the volume thereof can vary in different surface areas of the fire protection board.
  • the fire protection agent is thus not provided homogeneously distributed over the surface of the fire protection board; Rather, a "dosage" of the fire retardant at the desired positions.
  • the fire retardant is targeted at particularly critical points and in each case an appropriate amount, so that a particularly good fire protection effect is achieved.
  • the fire protection according to EP 2 236 282 A1 further comprising an intumescent under heat additive. Since such a gap or cavity usually occurs in the edge region of the fire door, this intumescent additive is preferably used in the nests with fire retardants, which are adjacent to side edge portions of the plate.
  • the fire protection board according to EP 2 236 282 A1 has proven very successful in practice. However, it has been shown that further improvements with regard to the fire protection effect are also possible here. In particular, with the fire protection plate arranged inside this known fire protection plate, it is not possible in a sufficient manner with fire protection means to reliably prevent the circulation of hot gases in the door box, even if an intumescent additive is used.
  • thermal insulation composite body with improved thermal stability and improved fire behavior has become known.
  • This composite body and has two metal plates sandwiching therebetween a heat-insulating core, for example made of mineral wool. These elements are firmly connected by gluing together.
  • an intumescent mass is additionally arranged, which is arranged on the core material or a metal plate before the composite is produced. This foaming mass under heat could be mixed with the adhesive.
  • the intumescent mass can also be present on all sides of the core material or only on the glued with the metal plates large areas.
  • the composite body thus formed can be handled as one piece and used for the production of storage or cooling halls.
  • the EP 0 123 255 A1 discloses a fire protection element for a fire door or the like.
  • This is preferably formed from rock wool, which is at least partially impregnated with an intumescent agent.
  • the thus prepared rock wool plate is then received between frame elements, which are formed of wood or metal. This can equip doors, walls, ceilings, floors, ship wall elements or the like.
  • an intumescent agent has become known with which, among other things mineral wool plates can be soaked. The impregnation takes place, for example, along the narrow edges of the mineral wool slabs up to a predetermined penetration depth. Such prepared mineral wool panels can then be used in a metal jacket, whereby fire protection elements such as doors, walls, ceilings or the like can be formed. Even if hereby quite satisfactory fire protection properties are achieved, is at this fire protection element of disadvantage that the relatively expensive and Heavy fire protection agent is present in large quantities and thus the cost of production and handling of the fire protection element is large.
  • the invention has the object of developing a generic fire protection system such that the amount of fire retardant can be reduced without the fire protection effect suffers.
  • a correspondingly improved fire door, an improved fire wall element and a fire protection plate should be achieved for this purpose.
  • the present invention is the first time under heat foaming fire retardant targeted exactly in the subareas and especially on the surface of the fire protection plate and / or in the cavity of the receiving body, where the problem areas are expected, in addition also the amount of fire retardant on the Order range is varied specifically.
  • the fire protection agent can thus according to the invention freely stretched away from the surface of the fire protection plate or the receiving body and is dosed so that it closes any given there gap to a door leaf frame or the like. Reliable.
  • the fire-protection agent since the fire-protection agent is exposed to the temperature front almost unhindered, its effect within the scope of the invention is particularly rapid. Thus, a circulation of hot gases can be prevented early.
  • the invention further considered that it is not necessary to apply the fire protection over the entire surface on the entire surface of the fire protection plate and / or in the cavity of the receiving body, since the endangered in terms of the formation of cavities places only in certain areas, and there also in varying degrees, are given. Particularly affected here are typically all surface areas of the fire protection plate, which are arranged in the direction of heat to be prevented, such as the side edges of the fire protection plate or the inner surfaces of any breakthroughs, recesses or the like ..
  • the upper end of a fire door is particularly vulnerable with regard to the formation of cavities, since here the fire protection insert sag in the course of time and thereby release a free space.
  • the invention enables a particularly targeted and optimally distributed use of the fire protection agent.
  • the fire protection board according to the invention combines all the desired functions in a single piece to be handled, if the fire retardant is applied thereto, its further use, such as, for example, is made easier. the installation in a fire door. Furthermore, it can thus be avoided according to the invention that for this purpose several parts must be connected to each other, whereby the entry of additional fire load, e.g. can be bypassed by adhesive etc.
  • the fire protection agent can be applied alone on the fire protection board, alone on the inner surface in the cavity of the receiving body or at the same time at these two points. Depending on the particular application and the structural conditions, it is thus possible to choose the most suitable application method for the fire protection agent.
  • the invention provides a fire protection system in which the formation of cavities in the door leaf of a fire door or the like can be prevented particularly reliably with a limited use of fire protection, whereby a flow of hot gases around is even more purposefully reduced and a clear improvement in the fire protection effect can be achieved.
  • the variation of the amount of fire protection agent over the application area can be achieved by varying the amount thereof within an application site.
  • Such a configuration can be produced with little effort, since for this purpose, for example, a greater layer thickness of the fire protection agent than in other subareas is produced only in certain subregions of the application sites.
  • the amount of fire protection agent used can thus advantageously be kept particularly low at the same time.
  • the amount of fire protection agent is selected differently at the individual application sites. It is thus possible, for example, to provide a greater amount of fire-protection agent at the corresponding application site, specifically at an upper area of a fire-protection door, than at a further application site, for example in the area of a lock.
  • the expensive fire retardant can be used in a particularly targeted and economical manner.
  • the amount of the fire-retardant can be gradually reduced away from a critical point, which has the advantage that, with little use of material, a certain fire-protection effect still continues to exist in these transitional areas.
  • the critical point can be present more or less centrally within the order area or at the edge.
  • the fire protection agent can be arranged in at least one corner region formed by side edges of the fire protection plate and / or in the cavity of the receiving body. Just these corner areas with abutting side edges are according to experience critical areas in which cavities when used in a fire door or the like. May arise.
  • the invention with a small amount of fire retardant reliably achieved closing of such cavities in case of fire.
  • the fire protection means is arranged on at least one side edge surface of the fire protection plate and / or in the cavity of the receiving body. This makes it possible to reliably produce a closure between the fire protection panel and a door leaf frame of a fire door in this side edge area. This is particularly advantageous if the selected side edge surface is present in the upper end region of a fire door, since cavitation is most frequently encountered here. In addition, the temperature development in this upper region of a fire protection plate or a fire door is particularly extreme, so that the burden of the fire is particularly high here. The fire protection effect of the fire protection system according to the invention is thus further improved.
  • the fire protection agent is arranged circumferentially on all side edge surfaces of the fire protection plate and / or in the cavity of the receiving body. Then a particularly good fire protection effect is achieved especially in these critical areas, without an extremely large amount of fire retardants would have to be used.
  • the fire protection agent is also arranged in at least one subregion of at least one large area of the fire protection plate and / or in the cavity of the receiving body.
  • the sealing effect of the foaming fire protection agent is particularly good if it is not limited to the side edge regions of the fire protection board or the receiving body, but also includes subregions of at least one large area of the fire protection board or the receiving body , This is especially in the upper end of the fire protection plate when using a fire door or the like.
