Description

[0001] Fire protection profile system and an insulator for a fire protection profile system as well as manufacturing method of a fire protection profile system

[0002] The present invention relates to a fire protection profile system according to the preamble of patent claim 1, an insulator for a fire protection profile system according to the preamble of patent claim 19 and the use of the insulator for a fire protection profile system according to patent claim 20 as well as a manufacturing method of a fire protection profile system according to patent claim 21.

[0003] Technological background

[0004] Materials with low thermal conductivity are used in fire-resistant building elements such as doors, facades, partition walls, windows, fire-resistant compartments, fire enclosures for ducts, wires, and similar components in building construction. Heat flow in a solid is defined by its density, specific heat capacity, and thermal conductivity. The underlying heat transfer mechanism is referred to as thermal conduction. These materials are often referred to as coolants in the facade, door, or window construction industries, despite the fact that they may or may not exhibit negative enthalpy at certain temperatures, such as approximately 30–130 °C for physically bound water, 140–160 °C for the transition phase of gypsum anhydrite, 280–310 °C for ATH (aluminum trihydroxide), and approximately 320 °C for MDH (magnesium dihydroxide).In addition to those mentioned above, there are many other materials with negative enthalpies in certain elevated temperature ranges. All of these materials, or a combination of them (hybrid materials in layers or blends), have a common function: they delay the heating (or warming up) of the element to be protected by consuming heat through endothermic processes. The consumed heat is used for the reduction of binding energy, reaction energy, the phase change of the coolant itself, etc.

[0005] In principle, there are three different types of heat transport or heat transfer mechanisms: conduction, radiation, and convection, the latter requiring mass transport within a fluid. When heat is transferred from a convective medium to a solid medium, a so-called heat transfer resistance on the surface of the solid material creates an additional heat transfer barrier.

[0006] A common design strategy for high-temperature or fire protection applications in building construction is to improve the performance of the thermal barrier to reduce the temperature of the element to be protected from overheating, or the temperature on the far side of the fire, for a given thickness (or geometric configuration) of the protective material / coolant. A similar design strategy aims to reduce the thickness of the protective material to prevent a certain temperature of the protected element from reaching. Sometimes a combination of the above strategies is used.

[0007] Standard profiles with standard dimensions are used, particularly in the window, door, and facade industries. Using a fire door profile as an example, it is important to delay the temperature rise on the user side, or the non-fire-loaded side of the door, as much as possible, or to keep it below a given limit for a given time, given a defined temperature rise on the fire side, or the fire-loaded side. Very often, the thermal transmittance cannot be reduced sufficiently to meet structural requirements.

[0008] EP 1 020 608 A1 is known from the prior art. This discloses a composite profile for frames of wall elements, doors, or windows, comprising at least one outer profile and one inner profile, which are connected to each other and held at a distance from each other. A gap is formed between the profiles in which a fire- and / or heat-resistant insulation material is arranged. The insulation material rests snugly against the outer profile and the inner profile and is held in place by bolts.

[0009] Furthermore, DE 4240234 A1 is known. This discloses a frame construction for surface elements made of frame profiles, consisting of an inner shell and an outer shell arranged at a distance from it. The facing inner surfaces of the inner shell and outer shell are arranged at a distance from each other in the final assembly state to form an air gap between them.

[0010] The disadvantage of the known solution is that an insulating material is arranged between the outer shell and the inner shell, which encloses the air gap and thus the outer shell is firmly connected to the inner shell by means of the insulating material even in the event of a fire.

[0011] Description of the invention

[0012] An object of the invention is to avoid at least one of the disadvantages of the prior art and, in particular, to create an improved fire protection profile system in order to utilize an alternative heat transport mechanism to the conventional heat transfer mechanism used in fire protection elements. Furthermore, an improved insulator and the use of the insulator in, for example, a fire protection profile system are to be created, as well as an improved manufacturing method.

[0013] This problem is solved by the features of the independent patent claims. Advantageous further developments are set forth in the figures and in the dependent patent claims.

[0014] A fire protection profile system according to the invention, particularly in building construction, comprises at least one outer profile and at least one inner profile, wherein the at least one outer profile and the at least one inner profile are spaced apart from one another, and comprises at least one insulator which is arranged between the at least one outer profile and the at least one inner profile, or is arranged in the at least one outer profile and / or in the at least one inner profile. The at least one insulator comprises at least one heat transfer layer, wherein the at least one heat transfer layer is designed to separate the at least one outer profile or the at least one inner profile from a fire in order to create at least a reduced heat transfer in or between the at least one outer profile and the at least one inner profile.This fire protection profile system provides a new means of reducing heat transfer in building construction, for example, in fire protection elements such as fire barriers, partition walls, and the like, by incorporating at least one or more heat transfer layers. This prevents heat from spreading in the event of a fire, originating from a fire outside the fire protection profile system, from the area surrounding the outer profile to the area surrounding the inner profile. A heat transfer layer in the event of a fire is defined by the transition from heat conduction in a solid body to heat transfer by radiation into the environment, particularly in combination with convection. In general, heat transfer is the heat transfer between the surface of a solid body and a moving fluid or gas. In this case, additional heat transfer resistances are activated.It is known that heat transfer occurs via a heat transfer layer such as air, but this is not the dominant mechanism at higher temperatures above approximately 400°C, especially not in the center of a fire protection profile system at the location of the heat transfer layer. In the event of a fire, i.e., at temperatures above approximately 400°C, radiation is the dominant heat transfer mechanism.

[0015] The heat transfer layer acts as an infrared radiation layer, and in the case of an air gap as a heat transfer layer, this acts as an infrared radiation gap to efficiently promote reduced heat transfer to the environment.

[0016] Compared to the known use of (insulator) materials with low thermal diffusivity in fire protection profile systems, the disclosed solution offers a significant advantage in fire protection in buildings. The at least one insulator comprises at least one fire- and / or heat-resistant material that is neither flammable nor promotes smoke development. In addition, at least the outer profile can comprise at least one fire- and / or heat-resistant material, for example, an insert as an additional heat transfer layer, and alternatively or additionally, the inner profile can comprise a fire- and / or heat-resistant material that serves as additional insulators.The at least one outer profile and optionally also the at least one inner profile can be closed profiles or can be open on at least one side of the profile, so that the at least one insulator extends at least partially into the profiles when arranged between the profiles. In a further embodiment, the at least one outer profile and optionally also the at least one inner profile can be a flat profile, such as a flat steel profile.

[0017] In general, heat transfer is the transport of energy in the form of heat across at least one thermodynamic system boundary. There are three types of heat transfer processes: through mechanical contact, convection – the entrainment of thermal energy in a flowing medium, and thermal radiation, i.e., electromagnetic waves. This type of heat transfer can be effectively prevented in the present fire protection profile system.

[0018] In particular, the heat transfer layer extends in at least two spatial directions along the longitudinal extent of the outer profile or the inner profile, so that the heat transfer layer is designed to spatially separate the at least one insulator from the at least one outer profile or from the at least one inner profile, at least in sections.

[0019] Preferably, the at least one heat transfer layer is an air gap. Since air has low thermal conductivity and also generates thermal transfer resistance, heat transfer between the environment of the at least one outer profile and the environment of the at least one inner profile is greatly reduced. Furthermore, at higher temperatures, heat transfer by radiation via the air gap dominates. The air gap preferably extends in a direction normal to a longitudinal extent of the insulator and has an air gap thickness of at least 5% of the thickness of the at least one insulator and preferably has a minimum thickness of 0.5 mm. This provides an air gap sufficiently dimensioned for fire protection and achieves efficiently reduced heat transfer. In particular, the air gap extends in at least two spatial directions along the longitudinal extent of the outer profile orof the inner profile, so that the air gap is designed to at least spatially completely separate the insulator from at least one outer profile and / or from at least one inner profile.

[0020] Alternatively or additionally, the at least one insulator is arranged between the at least one outer profile and the at least one inner profile such that it is spaced at least from the at least one outer profile or from the at least one inner profile, so that at least one air gap forms as a heat transfer layer between the at least one outer profile and the at least one insulator or between the at least one inner profile and the at least one insulator. The at least one insulator can be formed in one piece and separated from the at least one outer profile or from the at least one inner profile by means of spacer elements. This allows for simple manufacture of the fire protection profile system.

[0021] In particular, the air gap extends substantially parallel to the at least one inner profile and, alternatively or additionally, parallel to the at least one outer profile, and advantageously over the entire length of the at least one insulator. Thus, the at least one insulator consists of at least two separate and spaced-apart insulator parts, wherein both insulator parts are arranged between the at least one outer profile and the at least one inner profile during the manufacture of the fire protection profile system in such a way that at least one air gap forms a hollow space between them.

[0022] Preferably, the at least one insulator has at least one further heat transfer layer, which is designed in particular as a further air gap. This creates at least one further reduced heat transfer between the at least one outer profile and the at least one inner profile, so that heat transfer is prevented to an improved extent.

[0023] In particular, the at least one outer profile has an average or minimum surface roughness of at least 0.05 mm. Thus, the at least one outer profile and the insulator rest on one another at points. Due to the surface roughness, the at least one outer profile has a surface structure with peaks and valleys, with multiple heat transfer layers forming in the valleys. The at least one outer profile can have a structured surface or textured surface along its longitudinal extent as a possible manifestation of rough surfaces.

[0024] In particular, the at least one inner profile has an average or minimum surface roughness of at least 0.05 mm. Thus, the at least one inner profile and the insulator rest on one another at points. Due to the surface roughness, the at least one inner profile has a surface structure with peaks and valleys, with multiple heat transfer layers forming in the valleys. The at least one inner profile can have a structured surface or a textured surface along its longitudinal extent as a possible manifestation of rough surfaces.

[0025] In particular, at least one insulator has an average or minimum surface roughness of at least 0.05 mm. Thus, the at least one insulator and the at least one inner profile or the at least one outer profile rest on one another at points. Due to the surface roughness, the at least one insulator has a surface structure with peaks and valleys, with multiple heat transfer layers forming in the valleys. The at least one insulator can have a structured surface or a structured surface along its longitudinal extent as a possible manifestation of rough surfaces.

[0026] In particular, at least one heat transfer layer has an average or minimum surface roughness of at least 0.05 mm. Thus, the at least one heat transfer layer and the at least one insulator rest on one another at specific points. Due to the surface roughness, the at least one heat transfer layer has a surface structure with peaks and valleys, with multiple air gaps forming in the valleys in this embodiment. Preferably, the at least one heat transfer layer separates the insulator, at least in some regions, into at least two insulator parts upon reaching a threshold temperature. Thus, an air gap only forms in the event of a fire. In such a case, the fire protection profile system is heated from the fire side, leading to an elevated temperature in the at least one insulator.

[0027] In particular, the at least one heat transfer layer comprises a material that is different from the material of the at least one insulator. Some materials, such as unfilled thermoplastic polymers such as PP or PE, are known to completely dissolve at elevated temperatures through pyrolysis or chemical degradation at a certain temperature. For example, the material of the at least one heat transfer layer can comprise polystyrene, cellulose, or a low-melting metal alloy or a low-melting metal material.

[0028] Preferably, the at least one heat transfer layer is designed such that, upon reaching the threshold temperature, it deforms at least in a direction normal to the longitudinal extension of the insulator. Some materials, such as calcium sulfate-based mixtures or mineral mixtures such as concrete, mortar, or mixtures containing organic fibers, e.g., cellulose, are known to shrink at elevated temperatures either through chemical or physical processes such as drying or chemical decomposition and / or chemical reactions.

[0029] In particular, the at least one heat transfer layer is designed to deform at least in the direction normal to the longitudinal extension of the insulator upon reaching the threshold temperature, so that at least one air gap is formed between the at least two insulator parts.

[0030] Preferably, at least one of the insulator parts is designed to deform upon reaching the threshold temperature, at least in the direction normal to the longitudinal extension of the insulator, such that at least one air gap forms in the fire protection profile system. Assuming a fire starts in the area of ​​the at least one inner profile and the at least one outer profile is facing away from the fire: When the air gap forms and heat transfer is thus reduced, the outer side of the fire protection profile system receives less heat, causing the temperature on the inner side to continue to rise sharply. This leads to further shrinkage of the at least one insulator part or the at least one heat transfer layer. As a result, the air gap thickness will continue to increase during the fire event. This enables a stable and virtually self-reinforcing thermal separation in the fire protection profile system.

[0031] Preferably, the threshold temperature is greater than 90°C. This allows a material such as gypsum-containing mixtures to be used for the heat transfer layer or the at least one insulator, which is sufficiently stable under operating conditions, including a temporary temperature increase. Such materials are easy to store without changing their shape.

[0032] The threshold temperature is preferably greater than 200°C. This allows the use of a material such as modified gypsum mixtures comprising anhydrite in various phases that is sufficiently stable under operating conditions, including a temporary temperature increase to which a fire protection profile system is exposed, for example, during powder coating. Therefore, when specifying the material for the heat transfer layer or for the at least one insulator, the desired shrinkage should only begin at approximately 200°C. Considering a preferred geometric configuration of the fire protection profile system, it is therefore advantageous to control the shrinkage so that it occurs primarily in the direction normal to the longitudinal extension of the insulator.

[0033] Preferably, the material of the at least one heat transfer layer or the material of the at least one insulator comprises at least fibers made of glass, metal, or textile, such as aramid, or others. Using such materials, the shrinkage of the at least one insulator or the heat transfer layer in a preferred dimension is easy to control, and mechanical reinforcement of the at least one heat transfer layer or the at least one insulator is possible, in particular with directional long or short, straight, curved, or bent fibers and other similar materials. In such a configuration, the air gap retains its dimensions even under structural loads such as bending or torsion.

[0034] Preferably, at least one low-emissivity coating is present in the insulator to reduce radiant heat transfer in the event of a fire. A coating can also comprise a layer such as a foil, which is arranged on or in the insulator, or in which the insulator is arranged. In particular, at least one metal coating is present in or on the insulator. This would be a cheap, high-performance solution to reduce radiant heat transfer in the event of a fire. A readily available solution consists of at least one layer of aluminum foil. Depending on the application, this can also be any low-emissivity coating, e.g., copper foil, nickel foil, steel foil, stainless steel foil, or even titanium foil. Non-metallic low-emissivity foils such as Mylar, Kapton, or similar foils can also be used.In cases where a foil is used, it can be glued to the insulator surfaces or fixed by crimping or by other mechanical or chemical bonding or by sheathing.

[0035] The at least one coating is preferably arranged on at least one insulator side of the insulator. The coating is attached to an insulator side and can thus efficiently reduce radiant heat transfer in the event of a fire. Advantageously, the at least one coating is arranged on an insulator side that is aligned normally to the at least one outer profile or the at least one inner profile - i.e. a lateral insulator side. The at least one coating is preferably arranged on at least one side of the at least one heat transfer layer. A solution that is easy to produce consists of a coating on the side of the at least one insulator facing the air gap. For example, the coating can comprise a paint, such as a zinc paint. In particular, the at least one coating adheres to the at least one insulator so that it does not or only very slightly detaches in the event of a fire.can only be detachable from at least one insulator.

[0036] Alternatively or additionally, the heat transfer layer has a coating on at least one side of the heat transfer layer, for example, on the top and bottom. This provides coatings on both sides of the air gap, further reducing radiant heat transfer in the event of a fire.

[0037] A further preferred embodiment provides for a reflection layer (layer with reduced emissivity) present at least on one side, wherein the orientation takes place in the plane spanned by the longitudinal extent of the insulator and the vector which is perpendicular to the heat transfer layer and thus, for example, faces a filling element.

[0038] Preferably, the at least one coating has a perforation. It is possible that the insulating material releases water or water vapor or other gases or liquids upon heating and / or during shrinkage. These gases and / or liquids could move towards the cooler side of the insulator and thus reach the surface facing the air gap, where they condense or accumulate, thus closing the air gap. To prevent this, perforated coatings can be used through which gases or liquids can penetrate without collecting behind the coating. The accumulation of water droplets or hot steam inside the thermal break should not impair the performance of the thermal break itself, provided they do not act to bridge the gap. The insulator preferably releases water vapor upon reaching the threshold temperature.

[0039] Preferably, the at least one insulator is connected to the at least one outer profile. This securely fixes the at least one insulator to the outer profile. In particular, the insulator is connected to the at least one outer profile with a dimensionally stable connection, meaning that the at least one connection ensures a firm and unalterable link between the at least one insulator and the at least one outer profile. This prevents the at least one insulator from detaching from the outer profile. Preferably, the at least one insulator is attached to the outer profile with an adhesive, which can withstand elevated temperatures without expanding. This forces the at least one insulator to open at the desired location and shrink toward the outer profile.

[0040] Advantageously, the at least one insulator is arranged in the at least one outer profile and connected to the at least one outer profile at least on an inner side of the at least one outer profile. The heat transfer layer is arranged on a further inner side of the at least one outer profile in order to create at least a reduced heat transfer between the at least one outer profile and the at least one inner profile. Alternatively or additionally, the insulator is connected to the at least one inner profile. This means that the at least one insulator is stably fixed to the inner profile. In particular, the insulator is connected to the at least one inner profile with a dimensionally stable connection, which means that the at least one connection ensures a firm and unchangeable connection between the at least one insulator and the at least one inner profile. This can prevent the at least one insulator from becoming detached from the inner profile.Preferably, the at least one insulator is attached to the inner profile with an adhesive, which can withstand higher temperatures without expanding. This forces the at least one insulator to open at the desired location and shrink toward the inner profile.

[0041] Advantageously, the at least one insulator is arranged in the at least one inner profile and is connected to the at least one inner profile at least on one inner side of the at least one inner profile. The heat transfer layer is arranged on another inner side of the at least one inner profile in order to at least reduce heat transfer between the at least one outer profile and the at least one inner profile.

[0042] In a preferred fire protection profile system, at least one insulator is arranged between the at least one outer profile and the at least one inner profile, and at least one further insulator is arranged in the outer profile or in the inner profile. The at least one heat transfer layer is preferably present in the at least one outer profile or in the at least one inner profile. In addition, both the at least one outer profile and the at least one inner profile have a heat transfer layer.

[0043] The present fire protection profile system provides a novel means of reducing heat transfer by incorporating at least one or more heat transfer layers, thus counteracting the spread of heat between the area surrounding the outer profile and the area surrounding the inner profile in the event of a fire. Compared to the known use of materials with low thermal diffusivity in fire protection profile systems, the disclosed solution offers a significant advantage in maintaining the protection objectives.

[0044] Preferably, at least one connecting element is provided between the at least one outer profile and the at least one inner profile for the dimensionally stable interaction of the fire protection profile system, thus preserving the integrity and stability of the fire protection profile system.

[0045] The arrangement with the at least one connecting element is designed to be dimensionally stable under normal application conditions, meaning that the at least one connecting element ensures a firm and unchanging connection between the at least one inner profile and the at least one outer profile. This dimensional stability ensures that the fire protection profile system maintains constant stiffness and strength under typical loads and in common application environments. However, under special conditions, particularly under the influence of extreme temperatures such as during a fire, the fire protection profile system is designed such that the at least one connecting element may exhibit a modified response.Some of these connecting elements may lose some or all of their stiffness, which causes them to become more flexible and thus reduces the ability of the overall structure to bear forces or loads in the usual way.

[0046] Preferably, the at least one connecting element is a connecting bolt. Such a connection can be achieved, for example, by individual connecting bolts with a predefined spacing, which are, for example, welded or riveted to the outer profile and are drilled centrally through the at least one insulator and enable its free contraction.

[0047] In particular, the at least one connecting bolt is a hollow bolt. Bolts or connecting elements provide a direct heat transfer path from the at least one outer profile to the at least one inner profile. Hollow bolts have a reduced cross-section and thus reduced heat transfer.

[0048] In particular, the at least one connecting bolt comprises a bone or hourglass shape, i.e. a slimming in the cross section or alternatively truss structures.

[0049] In particular, the at least one connecting element has a Z-shape or an S-shape. The length of the heat transfer path is an important factor for heat flow. Curved bolt shapes or straight but inclined bolt shapes, such as Z-shaped or S-shaped bolts, can be used to directly influence and significantly reduce heat flow in the connecting elements.

[0050] Preferably, the at least one connecting element consists of a material with a melting point of less than 400°C. In the event of a fire, such connecting elements would melt, thus interrupting the heat flow within the connecting element. Alternatively, the connecting elements can be non-metallic connecting elements, which also melt in the event of a fire. Alternatively, the fastening element can be temperature-sensitive and melt in the event of a fire, as is possible with solders or adhesives, for example.

[0051] In particular, the at least one insulator rests on at least one projection on the at least one connecting element to form the at least one heat transfer layer to the at least one outer profile or to the at least one inner profile. This makes it easy to form a spacer element that ensures that the at least one heat transfer layer can form.

[0052] Preferably, the at least one outer profile has at least one opening arranged adjacent to the at least one heat transfer layer. This reduces contact between the at least one outer profile and the at least one insulator. The resulting gaps enlarge the at least one heat transfer layer, which transfers less heat because the facing surfaces have low emissivity in the event of a fire.

[0053] In particular, the at least one outer profile has a plurality of openings arranged adjacent to the at least one heat transfer layer. The plurality of openings are arranged next to one another on the at least one outer profile. This creates an enlarged heat transfer layer along the at least one outer profile and significantly reduces heat transfer.

[0054] Alternatively or additionally, the at least one inner profile has at least one opening arranged adjacent to the at least one heat transfer layer. This reduces contact between the at least one inner profile and the at least one insulator. The resulting gaps enlarge the at least one heat transfer layer, which transfers less heat, since the facing surfaces have low emissivity in the event of a fire.

[0055] In particular, the at least one inner profile has a plurality of openings arranged adjacent to the at least one heat transfer layer. The plurality of openings are arranged next to one another on the at least one inner profile. This creates an enlarged heat transfer layer along the at least one inner profile and significantly reduces heat transfer.

[0056] In particular, the at least one insulator rests at least partially against an edge region of the at least one opening. The at least one insulator can be easily fixed to the edge region of the openings of the at least one inner profile and thus held securely.

[0057] In particular, the at least one insulator rests at least partially against an edge region of the plurality of openings. The at least one insulator can be easily fixed to the edge region of the plurality of openings of the at least one inner profile and thus held securely.

[0058] Preferably, the at least one outer profile has at least one point- or line-shaped bead extending toward the at least one insulator. Such a bead forms an air gap that serves as a heat transfer layer. At the same time, the bead holds the at least one insulator stationary between the at least one outer profile and the at least one inner profile, making it easy to fix.

[0059] Alternatively or additionally, the at least one inner profile has at least one bead extending toward the at least one insulator. Such a bead forms an additional air gap, which serves as an additional heat transfer layer. At the same time, the bead holds the at least one insulator in place between the at least one inner profile and the at least one inner profile, making it easy to fix.

[0060] Preferably, the at least one bead extends along the longitudinal extent of the at least one outer profile, so that the at least one heat transfer layer extends along the entire at least one outer profile.

[0061] Alternatively or additionally, the at least one bead extends along the longitudinal extent of the at least one inner profile, so that the at least one heat transfer layer extends along the entire at least one inner profile.

[0062] An insulator according to the invention has at least one heat transfer layer to create at least a reduced heat transfer between at least one outer profile and at least one inner profile. The insulator provides a novel means of reducing heat transfer, for example, in fire protection elements such as fire barriers, partition walls, and the like, by incorporating at least one or more heat transfer layers, thus counteracting the spread of heat in the event of a fire. Alternative applications for an insulator according to the invention include, for example, fire protection casings or cladding or fillings for fire protection elements such as partition walls, as well as the protection of ventilation ducts and pipes.

[0063] Furthermore, the invention discloses the use of an insulator for a fire protection profile system in a profile system, particularly for building construction. This also includes uses as fire protection casings or fillings for fire protection elements such as partition walls, as well as protection of ventilation ducts and pipes. A manufacturing method for a fire protection profile system according to the invention comprises at least the following steps: a. Providing at least one inner profile and one outer profile; b.Arranging at least one insulator between the inner profile and the outer profile or in the at least one outer profile and / or in the at least one inner profile, wherein the at least one insulator comprises at least one heat transfer layer and / or the at least one insulator is arranged in or between the at least one outer profile and the at least one inner profile such that the at least one insulator is spaced at least from the at least one outer profile or from the at least one inner profile, so that an air gap is formed therebetween as a heat transfer layer.

[0064] This manufacturing process provides a new fire protection profile system for reducing heat transfer in building construction, for example, in fire protection elements such as fire barriers, partition walls, and the like, by incorporating at least one or more effective or latent heat transfer layers, thus counteracting heat spread in the event of a fire. The disclosed solution offers a significant advantage in passive fire protection compared to the conventional use of materials with low thermal diffusivity in fire protection profile systems.

[0065] The at least one outer profile and optionally also the at least one inner profile can be open on at least one profile side, so that the at least one insulator extends at least partially into the profiles when it is arranged between the profiles.

[0066] Preferably, before or after step a., at least one surface on the at least one insulator and / or on the at least one inner profile and / or on the at least one outer profile is roughened, wherein the average or minimum surface roughness is in particular at least 0.05 mm. Thus, the at least one inner profile or the at least one outer profile and the insulator rest on one another at points. Due to the average surface roughness, the at least one inner profile or the at least one outer profile and the at least one insulator have a surface structure with peaks and valleys in a boundary region, with multiple heat transfer layers forming in the valleys.

[0094] Implementation of the invention

[0095] Figure 1 shows a first embodiment of a fire protection profile system 20 with an outer profile 22 and an inner profile 24, wherein the outer profile 22 and the inner profile 24 are spaced apart from one another. Fire- and / or heat-resistant inserts 23, 25 are arranged in the outer profile 22 and the inner profile 24 as insulators. The outer profile 22 and the inner profile 24 are mechanically connected to one another with one or more spaced-apart connecting bolts 27, wherein the connecting bolt 27 is welded to the outer profile 22 and the inner profile 24. The fire protection profile system 20 has an insulator 30 arranged between the outer profile 22 and the inner profile 24. The connecting bolt 27 is drilled centrally through the insulator 30 and enables its free contraction.The insulator 30 is attached to the outer profile 22 on the one hand and to the inner profile 24 on the other hand with an adhesive, whereby the adhesive can withstand higher temperatures without expansion.

[0096] The insulator 30 consists of a first insulator part 32 and a second insulator part 34 and includes an air gap 40 as a heat transfer layer to create at least a reduced heat transfer or heat transport between the outer profile 22 and the inner profile 24. Since air has low thermal conductivity and also generates heat transfer resistance, heat transfer between the outer profile 22 and the inner profile 24 is greatly reduced. The air gap 40 extends over the entire length of the insulator 30 parallel to the inner profile 24 and parallel to the outer profile 22. The insulator 30 comprises a fire- and / or heat-resistant material.

[0097] The insulator 30 has a low-emissivity coating 50 on an inner surface 37 to reduce radiant heat transfer in the event of a fire. The coating 50 shown comprises a zinc paint and adheres to at least one insulator 30.

[0098] Figure 2 shows a second embodiment of a fire protection profile system 120 in building construction with the outer profile 22 and the inner profile 24 according to the embodiment of the fire protection profile system 20 from Figure 1, wherein the insulator 130 consists of a first insulator part 132 and a second insulator part 134 as well as a third insulator part 136, and wherein an air gap 140, 141 is arranged as heat transfer layers between the insulator parts 132, 134, 136.

[0099] Figure 3 shows a third embodiment of a fire protection profile system 220 in building construction with an outer profile 222 and an inner profile 224 according to the embodiment of the fire protection profile system 20 from Figure 1, wherein the insulator 230 is formed in one piece and an air gap 240, 241 is present between one side of the insulator 230 and the outer profile 222 and one side of the insulator 230 and the inner profile 224.

[0100] Figures 4 to 6 show a fourth embodiment of a fire protection profile system 320 in building construction with the outer profile 22 and the inner profile 24 according to the embodiment of the fire protection profile system 20 from Figure 1, wherein the outer profile 22 and the inner profile 24 are spaced apart from one another.

[0101] The insulator 330 consists of a first insulator part 332 and a second insulator part 334 and comprises a heat transfer layer 345 to create a reduced heat transfer or heat transport between the outer profile 22 and the inner profile 24 (Figure 4). In this embodiment, the heat transfer layer 345 comprises a material that is different from the material of the at least one insulator 330. The heat transfer layer 345 extends over the entire length of the insulator 330 parallel to the inner profile 24 and parallel to the outer profile 22. The heat transfer layer 345 separates the insulator 330 into the two insulator parts 332, 334, whereby an air gap 340 is formed instead of the heat transfer layer 345 only in the event of a fire and when a threshold temperature is reached (Figure 5). Some materials, such asUnfilled thermoplastic polymers such as PP or PE are known to completely dissolve at elevated temperatures through pyrolysis or chemical degradation at a certain temperature. The heat transfer layer 345 comprises textile fibers. Using such materials, the shrinkage of the heat transfer layer 345 is easily controlled in a preferred dimension.

[0102] In this embodiment, the insulator 330 has a low-emissivity coating 350 on an inner surface 337 to reduce radiant heat transfer in the event of a fire. The coating 350 shown consists of a layer of aluminum foil bonded to the inner surface 337 of the insulator part 332 (Figure 6).

[0103] In an alternative embodiment, the heat transfer layer is designed to shrink at least in the direction normal to a longitudinal extension of the insulator upon reaching the threshold temperature, thus forming an air gap between the two insulator parts. Some materials, such as calcium sulfate-based mixtures or mineral mixtures such as concrete and mortar, or mixtures containing organic fibers, such as cellulose, are known to shrink at elevated temperatures either through chemical or physical processes such as drying or chemical decomposition and / or chemical reactions.

[0104] In an alternative embodiment, the insulator comprises more than two insulator parts, between each of which a previously described heat transfer layer is formed. Upon reaching the threshold temperature, the heat transfer layers shrink at least in the direction normal to the longitudinal extension of the insulator and form several air gaps between the insulator parts.

[0105] Figures 7 to 9 show a fifth embodiment of a fire protection profile system 420 with an outer profile 22 and an inner profile 24 according to the embodiment of the fire protection profile system 20 from Figure 1, wherein the outer profile 22 and the inner profile 24 are spaced apart from one another.

[0106] The insulator 430 consists of a first insulator part 432 and a second insulator part 434, which initially fit tightly against one another (Figure 7). Upon reaching the threshold temperature, the insulator parts 432, 434 are designed to shrink at least in the direction normal to the longitudinal extension of the insulator 430, such that an air gap 440 forms in the fire protection profile system over time (Figure 8). When the air gap 440 forms and heat transfer due to radiation is forced to the outside of the fire protection profile system 420, the outside of the fire protection profile system 420 receives less heat from the source of the fire, causing the temperature on the inside to continue to rise sharply. This leads to further shrinkage of the insulator parts 432, 434. As a result, the air gap thickness will continue to increase during the fire event (Figure 9).

[0107] The insulator parts 432, 434 are made of aramid. Using such materials, the shrinkage of the insulator parts 432, 434 in the direction normal to the longitudinal extension of the insulator 430 is easily controlled. Aluminum foils 450, 451, which have perforations, are glued to the inner sides 437, 438 of the insulator parts 432, 434. When heated and during shrinkage, the insulator material can release water or water vapor, which moves through the perforation toward the cooler side of the insulator part 432, 434 and thus reaches the surface facing the air gap 440.

[0108] Figures 10 to 13 show a further embodiment of a fire protection profile system 520, 620, 720, 820 in building construction with an outer profile 22 and an inner profile 24 according to the embodiment of the fire protection profile system 20 from Figure 1, wherein the heat transfer layer or the air gap in the insulators 530, 630, 730, 830 are designed differently. In Figure 10, the heat transfer layer or air gap 540 runs in a zigzag shape along the longitudinal extension of the insulator 530. In Figure 11, the heat transfer layer or air gap 640 runs in a triangular shape along the longitudinal extension of the insulator 630. In Figure 12, the heat transfer layer or air gap 740 runs in the shape of a circular segment along the longitudinal extension of the insulator 730. In Figure 13, the heat transfer layer or air gap 840 runs in a trapezoidal shape along the longitudinal extension of the insulator 830.

[0109] Figures 14 to 16 show a further embodiment of a fire protection profile system 920 with an outer profile 922 and an inner profile 924 according to the embodiment of the fire protection profile system 20 from Figure 1, wherein the outer profile 922 and the inner profile 924 are spaced apart from one another. The outer profile 922 and the inner profile 924 are connected by a plurality of connecting elements designed as hollow bolts 927. A first insulator 930 is arranged between the outer profile 922 and the inner profile 924, which first insulator rests against the outer profile 922 and the inner profile 924 and is fixed by means of the hollow bolts 927. An insert 23 is arranged in the outer profile 922 as a second insulator. The outer profile 922 has a plurality of openings 928 on the side of the outer profile 922 facing the first insulator 930. The insert 23 is placed on a side of the outer profile 922 facing away from the openings 928 and is positively connected to this side.An air gap 940 is provided as a first heat transfer layer between the insert 23 and the plurality of openings 928 in the outer profile 922, so that a cavity is formed along the longitudinal extent of the outer profile 922, which also extends into the plurality of openings 928 of the outer profile 922.

[0110] An insert 25 is arranged in the inner profile 924 as a further insulator. The inner profile 924 has a plurality of openings 929 on the side of the inner profile 924 facing the first insulator 930. The insert 25 is placed on a side of the inner profile 924 facing away from the openings 929 and is positively connected to this side. A further air gap 941 is present between the insert 25 and the plurality of openings 929 in the inner profile 924 as a further heat transfer layer, so that a cavity is formed along the longitudinal extent of the inner profile 924, which also extends into the plurality of openings 929 of the inner profile 924.

The outer profile 922 and the inner profile 924 are connected by a plurality of connecting elements, which are designed as Z-shaped connecting bolts 1027.

The air gaps 1140, 1141 are provided by means of beads 1138, 1139, which are formed in the outer profile 1122 and the inner profile 1124, respectively, and whose bead curvature is formed in the direction of the insulator 1130. Such a bead 1138, 1139 enables the formation of an air gap 1140, 1141 between the insulator 1130 and the outer profile 1122 or the inner profile 1124, which serves as a heat transfer layer.At the same time, the bead 1138, 1139 holds the insulator 1130 firmly in place between the outer profile 1122 and the inner profile 1124, ensuring it is easily fixed. Additionally, connecting bolts 1127 may be provided to hold the insulator 1130 securely in place - see Figure 19.
