Definitions

• the present invention relates in particular to a profile frame construction, in particular for windows or doors in fire protection design, as well as components of the profile frame construction with increased resistance to fire.
• the invention relates to a profile frame construction, in particular for windows or doors in fire protection design, in which two or more hollow profiles made of metal, in particular light metal such as aluminum, are connected to one another via heat-insulating insulating bars.
• a fire-resistant metal profile framework for windows, doors, facades, or glass roofs with a fire protection insert in the form of a molded body made of a heat-binding, hydrophilic absorber with a high water content.
• the metal profiles are preferably designed as hollow profiles, and the fire protection insert is arranged inside the hollow profiles.
• the fire protection insert consists of a gypsum-potassium-alum combination.
• Alum is generally capable of storing a high proportion of water of crystallization. If the framework or the fire protection inserts are exposed to a temperature above approximately 85°C, the water of crystallization is released and can cool the framework. In the event of a fire, this can extend the service life of the framework.
• fire protection inserts can have an insulating function and, in particular, a cooling function.
• the resistance to fire exposure of a framework made of metal profiles as described above is essentially limited by the water storage capacity of the material, which releases water under the influence of heat. Since the available internal space of the hollow sections is limited, the resistance to fire exposure attributable to the fire protection inserts cannot be increased indefinitely. For certain requirements, the achievable resistance to fire exposure is too low.
• the invention is based on the object of specifying a profile frame construction in fire protection design which, with the same installation space, has a higher resistance to the effects of fire than measures known from the prior art.
• a further object of the present invention is to provide a hollow profile for a fire protection construction, in particular for a profile frame construction in fire protection design, in which the service life of the hollow profile can be extended in the event of a fire in an easy-to-implement but nevertheless effective manner.
• Intumescent fire protection coatings are fire protection coatings based on substances that form foam layers and carbon in the event of a fire, film-binding binders, propellants, and conventional auxiliary materials and additives.
• Such intumescent fire protection coatings also known as intumescent coatings, are characterized by the fact that they foam up in the event of a fire under the influence of appropriate temperatures and, as a result of this foaming, the fire protection coating prevents or at least hinders the heat transfer to the coated component of the profile frame construction, in particular to the insulating bars of the profile frame construction.
• the intumescent fire protection coating is a fire protection coating with which the longest possible fire resistance times can be achieved with the smallest possible application quantities.
• the intumescent fire protection coating contains a flame-retardant mixture containing a phosphorus-nitrogen flame retardant and a phosphinic acid salt and/or a diphosphinic acid salt and/or their polymers.
• the phosphorus/nitrogen flame retardants can be, in particular, ammonium hydrogen phosphate, ammonium dihydrogen phosphate, and/or ammonium polyphosphate.
• the intumescent fire protection coating such as a multi-component epoxy resin coating compound with a first component containing at least one epoxy resin, a hardening component containing at least one hardener for the epoxy resin, and an intumescent component containing at least one acid component, at least one carbon source, and at least one gas generator.
• a fire protection insert made of a heat-binding, hydrophilic adsorber with a high water content can also be used.
• the advantages achievable with the solution according to the invention are obvious.
• the disintegration of the construction in the event of a fire can be delayed for a relatively long time, since the intumescent fire protection coating foams under the influence of heat and, as a heat shield, delays the disintegration process of the construction in the event of a fire.
• the intumescent fire protection coating can be applied particularly easily and simply, for example by spray coating, dip coating or painting, to the corresponding components of the profile frame construction without requiring additional installation space.
• At least one of the hollow profiles and preferably all hollow profiles of the profile frame construction are provided and, in particular, coated with an insulating layer-forming fire protection coating, at least partially or in some areas.
• the corresponding components of the profile frame construction can be coated directly with the intumescent fire protection coating using, in particular, a spray coating process, brushing process or dipping process.
• the insulating fire protection coating as an adhesive film, which is then glued to the corresponding components of the profile frame construction.
• the fire resistance of the profile frame construction can be significantly improved by choosing even low layer thicknesses for the intumescent fire protection coating.
• layer thicknesses for the intumescent fire protection coating in a range of approximately 200 ⁇ m to 5,000 ⁇ m, and preferably in a range of approximately 500 ⁇ m to approximately 3,000 ⁇ m, are sufficient.
• the invention further relates to a hollow profile for a fire protection structure, in particular for a profile frame structure in a fire-protection design of the aforementioned type according to the invention, wherein the hollow profile is equipped with at least one fire protection insert designed to extend the service life of the hollow profile in the event of a fire.
• This fire protection insert can, for example, be an insert made of a heat-binding, hydrophilic material with a high water content.
• the fire protection insert can also be formed from a material that expands in the event of a fire.
• the at least one fire protection insert is provided and in particular coated at least partially or in regions with an insulating layer-forming fire protection coating.
• At least one fire protection insert is directly coated with the intumescent fire protection coating.
