Definitions

  • the invention relates to a heat and / or sound insulation element Fire protection function, consisting of a hard foam panel, for example Made of expanded polystyrene, which hard foam sheet on one too insulating surface, in particular building facade or roof surface with Adhesives and / or holding elements can be attached and for the application of a Plaster is suitable, the hard foam plate two parallel to each other arranged large surfaces and four to the large surfaces in the has substantially perpendicular side faces.
  • Such heat and / or sound insulation elements are from the prior art Technology known.
  • thermal and / or acoustic insulation elements referred to as composite thermal insulation systems that consist of self-contained Insulation layers exist, which are reinforced by a Basic plaster and a plaster against weather influences and mechanical Effects are protected.
  • the heat and / or sound insulation elements are glued to the load-bearing surfaces of the building and / or by means of dowels inserted into the bearing surfaces Insulation holder held.
  • They are also composite thermal insulation systems known in which the heat and / or sound insulation elements are held in rails, which rails with the supporting surface are screwed.
  • These rails are double T-shaped, for example trained, the one T-bar is screwed to the building and the T-bar located away from the building in corresponding Recesses (grooves) of the heat and / or sound insulation elements engages.
  • Thermal insulation composite systems described above currently trained with heat and / or sound insulation elements, the one Have a material thickness between 60 and 80 mm. Due to the legal Requirements and that with the heat and / or sound insulation elements Achievable energy savings, the material thicknesses are increasing Tendency towards low energy houses, especially at Design of passive houses with insulation thicknesses of more than 300 mm.
  • the thermal and / or sound insulation is not to apply over the entire surface.
  • the design of the frame, in particular their construction height is therefore a determining factor in the thickness of the Thermal and / or soundproofing elements in lintel and reveal areas.
  • only heat and / or sound insulation elements can be used in these areas can be used with low material thickness.
  • thermal bridges are formed in these areas, which become more apparent with increasing insulation thickness.
  • reveal panels with larger sizes are increasingly used Material thickness or heat-insulating load-bearing building materials used, that reduce or even eliminate the thermal bridge effect.
  • the thermal insulation composite systems are located in the plinth areas through metal profiles, for example from perforated sheet metal completed.
  • the completion of the thermal insulation composite systems in the area of eaves or in the area of end panels Flat roof construction remains open, however.
  • cavities often remain, since the insulation boards are not completely in the area of the termination are led.
  • rigid foam panels made of expanded polystyrene are used as heat and / or soundproofing elements in thermal insulation composite systems. These hard foam sheets essentially have the advantage of being permanent and have relatively high transverse tensile strength and great rigidity.
  • Rigid foam panels made of polystyrene are of the building material class according to DIN 4102-1 B1 assigned, in which flame retardant building materials are classified are. This classification is based solely on the behavior of the Heat and / or soundproofing elements made of polystyrene when tested in the Brandschacht. Because heat and / or sound insulation elements made of polystyrene by melting the flame, is the classification for the above-mentioned building material class acceptable.
  • thermal and / or acoustic insulation elements made of polystyrene rigid foam are normal to highly flammable. Such heat and / or sound insulation elements drip burning, the fire process in addition to high energy turnover due to the release large quantities of smoke and toxic components is.
  • thermoplastics and / or wood Window and / or door frames burn down quickly and allow for Escape the fire in the facade area, where the fire quickly Edge areas of polystyrene insulation boards reached and ignited.
  • Another The weak point of such buildings is in the form of roller shutter boxes recognize that are covered with thin chipboard or plywood and have a polystyrene rigid foam lining on the inside or completely are made from molded polystyrene. About these roller shutter boxes the fire spreads rapidly, which then facade areas also reached and ignited.
  • these are in particular in the area of the building openings Soffit panels made of rigid polystyrene foam, where these hard foam panels first in the lintel area within a short time Melt time and the reinforced plaster layer connects to Remove the building so that the layer of plaster is partially or entirely from the Building is replaced and further building areas are released for the fire.
  • the reveal panels also melt, so that the thermal insulation composite system to the sides opens. Melt dripping on window sills intensified the thermal load also in the lower areas of the building opening, thereby causing devastating fire can lead to a crash of components of the plaster layer to lead.
  • the plaster layer hangs down like an apron directs the flames onto the polystyrene insulation layer, which melts or burns from the inside.
  • the flames strike the floor below.
  • the flames reach over the polystyrene rigid foam panels also the usually wooden roof structure in the eaves area, which then ignites.
  • thermal insulation composite systems with polystyrene rigid foam panels The fire risk when using thermal insulation composite systems with polystyrene rigid foam panels is well known. From the foregoing The reason for this is the assembly of such thermal insulation composite systems with polystyrene rigid foam panels on high-rise buildings, meeting places, Hospitals and / or airports not permitted. In These areas are only based on composite thermal insulation systems of non-flammable mineral wool, foam glass or aerated concrete slabs authorized. From an economic point of view, approval of the Composite thermal insulation systems described above with polystyrene rigid foam panels for a large number of buildings despite the given and identified risks.
  • An external cladding for buildings is known from DE 25 51 121 A1.
  • polystyrene insulation panels are attached to the outside of masonry, between which are horizontal strips of non-combustible material, For example, mineral wool are arranged on the outside of the building glued or otherwise attached.
  • the disadvantage of this The procedure consists on the one hand in the very complex processing of the individual elements of the outer cladding and the associated sources of error on the part of the construction workers. In addition, these are possible Failure of insufficient fire safety, which is also caused by the if necessary different adhesive masses is reinforced.
  • DE 196 43 618 A1 discloses a composite thermal insulation system plastic insulation boards made of hard foam, preferably attached to a facade made of polystyrene with the side facing away from the facade against a finishing plaster applied, if necessary, via reinforcement Weather influences are protected. It is also the subject of this stand technology an insulation board for this composite thermal insulation system.
  • the thermal insulation composite system or the previously known insulation board is characterized by the fact that between adjacent insulation boards in the area their roughly horizontal, adjoining edges provided with a flame retardant separating layer is switched on Fire in the event of foaming and curing of the flame retardant into one Interface stabilization leads.
  • a separating layer is used, for example fabric coated and / or impregnated with the flame retardant, which is, for example, a glass fiber fabric with an open fabric structure is. Such a fabric can be prefabricated as an angle Extruded profile to be formed.
