Description

[0001] 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 13 and the use of the insulator for a fire protection profile system according to claim 14 as well as a manufacturing method of a fire protection profile system according to claim 15. Technological background

[0002] 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 the like 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 window industry, despite the fact that they may or may not exhibit negative enthalpy at certain temperatures, such as 110–130 °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 at certain elevated temperature ranges.All these materials or a combination of these materials (hybrid materials in layers or mixtures) have a common function: they delay the heating (or warming up) of the element to be protected by consuming heat through endothermic processes, with the consumed heat being used for the reduction of binding energy, reaction energy, the phase change of the coolant itself, etc.

[0003] In principle, there are three different types of heat transfer mechanisms: conduction, radiation, and convection, the latter requiring a certain amount of 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.

[0004] A common design strategy for high-temperature 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 at a specific thickness (or geometric configuration) of the protective material / coolant. A similar design strategy aims to reduce the thickness of the protective material to achieve a specific temperature of the element to be protected. Sometimes a combination of the above strategies is used.

[0005] Standard profiles with standard dimensions are used, especially in the window industry. Using a fire door profile as an example, it is important to delay the temperature rise on the user side of the door as much as possible, or to keep it below a given limit, for a defined temperature rise on the fire side. Very often, the thermal transmittance cannot be reduced sufficiently to meet structural requirements.

[0006] 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. Description of the invention

[0007] 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 to utilize an alternative heat transport mechanism 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.

[0008] 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.

[0009] A fire protection profile system according to the invention for use 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 arranged between the at least one outer profile and the at least one inner profile. The at least one insulator comprises at least one heat transfer layer to create at least a reduced heat transfer between the at least one outer profile and the at least one inner profile.

[0010] The present fire protection profile system provides a novel 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, thus counteracting the spread of heat in the event of a fire. A heat transfer layer 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 process, additional heat transfer resistances are activated. Compared to the known use of materials with low thermal diffusivity in fire protection profile systems, the disclosed solution offers a significant advantage in firefighting in buildings.The at least one insulator comprises at least one fire- and / or heat-resistant material. Additionally, at least the outer profile can comprise a fire- and / or heat-resistant material, and alternatively or additionally, the inner profile can comprise a fire- and / or heat-resistant material. The outer profile and optionally also the inner profile 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.

[0011] 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: 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.

[0012] Preferably, the at least one heat transfer layer is an air gap. Since air has low thermal conductivity and also generates thermal resistance, heat transfer between the at least one outer profile and the at least one inner profile is greatly reduced. Furthermore, at higher temperatures, heat transfer via radiation dominates via the air gap. The air gap preferably extends in a direction normal to a longitudinal extension of the insulator and has an air gap thickness of at least 5% of the thickness of the at least one insulator, preferably with a minimum thickness of 0.5 mm. This provides an air gap sufficiently dimensioned for firefighting, and efficiently reduced heat transfer is achieved.

[0013] 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.

[0014] 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 exists between them.

[0015] 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.

[0016] Preferably, the at least one heat transfer layer separates the insulator, at least in part, into at least two insulator sections when a threshold temperature is reached. 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 a temporarily elevated temperature in at least one insulator.

[0017] 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.

[0018] Preferably, the at least one heat transfer layer is designed to deform at least in the direction normal to a longitudinal extension of the insulator upon reaching the threshold temperature. 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 due to chemical or physical processes such as drying or chemical decomposition and / or chemical reactions.

[0019] In particular, the at least one heat transfer layer is designed to deform at least in the direction normal to a 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.

[0020] Preferably, at least one of the insulator parts is designed to deform upon reaching the threshold temperature, at least in the direction normal to a 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 inner profile and the outer profile is facing away from the source of the fire: When the air gap forms and heat transfer is forced to the outside of the fire protection profile system due to radiation, the outside of the fire protection profile system 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 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, functioning thermal separation in the fire protection profile system.

[0021] 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 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.

[0022] 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.

[0023] Preferably, the material of the at least one heat transfer layer or the at least one insulator comprises at least textile fibers or fibers made of glass, metal, or aramid. Using such materials, the shrinkage of the at least one insulator or the heat transfer layer in a preferred dimension is easily controlled, and mechanical reinforcement of the at least one heat transfer layer or the at least one insulator is possible, in particular with oriented long or short textile fibers and other similar materials. In such a configuration, the air gap retains its dimensions even under structural loads such as bending or torsion.

[0024] 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 the insulator or in which the insulator is arranged. In particular, at least one metallic coating is present in the insulator. This would be a cheap, effective 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, 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 squeezing or by some other mechanical or chemical bond.

[0025] Preferably, the at least one coating is arranged on at least one side of the at least one heat transfer layer. A simple solution 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.

[0026] In particular, the at least one coating adheres to the at least one insulator so that it cannot detach from the at least one insulator in the event of a fire.

[0027] Preferably, the heat transfer layer has a coating 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.

[0028] Preferably, the at least one coating has a perforation. It is possible for the insulating material to release water or water vapor upon heating and during shrinkage. This water could move toward the cooler side of the insulator and thus reach the surface facing the air gap, where it could condense or accumulate. To prevent this, perforated coatings can be used, allowing moisture to pass through without accumulating 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. Preferably, the insulator releases water vapor upon reaching the threshold temperature.

[0029] 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. 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 higher temperatures without expanding. This forces the at least one insulator to open at the desired location and shrink toward the outer profile.

[0030] Alternatively or additionally, the insulator is connected to the at least one inner profile. This securely fixes the at least one insulator to the inner profile. In particular, the insulator is connected to the at least one inner profile with a dimensionally stable connection. This prevents the at least one insulator from detaching 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.

[0031] Preferably, at least one connecting element is provided between the at least one outer profile and the at least one inner profile to ensure the dimensionally stable interaction of the fire protection profile system, thus preserving the integrity and stability of the fire protection profile system. Such a connection can be achieved, for example, by individual connecting bolts with a predefined spacing, which are welded to the outer profile, for example, and drilled centrally through the at least one insulator, allowing its free contraction.

[0032] 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 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 heat transfer layers, thus counteracting the spread of heat in the event of a fire.

[0033] Alternative applications for an insulator according to the invention are, for example, fire protection casings or fillings for fire protection elements such as partition walls as well as protection of ventilation ducts and pipes.

[0034] Furthermore, the invention discloses the use of an insulator for a fire protection profile system in a profile system for building construction. This also includes uses as fire protection casings or fillings for fire protection elements such as partition walls, as well as for protecting ventilation ducts and pipes.

[0035] A manufacturing method according to the invention for a fire protection profile system 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, wherein the at least one insulator comprises at least one heat transfer layer and / or the at least one insulator is arranged 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.

[0036] 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 heat transfer layers, thus counteracting the spread of heat in the event of a fire. Compared to the conventional use of materials with low thermal diffusivity in fire protection profile systems, the disclosed solution offers a significant advantage in firefighting in buildings.

[0037] The outer profile and optionally also the inner profile can be designed to 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.

Implementation of the invention

[0045] Figure 1shows 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. 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, which is 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.

[0046] 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.

[0047] 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.

[0048] 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 the 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.

[0049] 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 the 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.

[0050] Figure 4 to Figure 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 the Figure 1 , wherein the outer profile 22 and the inner profile 24 are spaced apart from each other.

[0051] The insulator 330 consists of a first insulator part 332 and a second insulator part 334 and comprises a heat transfer layer 345 in order 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 430 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 only in the event of a fire and upon reaching a threshold temperature, an air gap 340 forms instead of the heat transfer layer 345 ( Figure 5 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. The heat transfer layer 345 comprises textile fibers. Using such materials, the shrinkage of the heat transfer layer 345 in a preferred dimension is easily controlled.

[0052] 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 ).

[0053] 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.

[0054] 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.

[0055] Figure 7 to Figure 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 the Figure 1 , wherein the outer profile 22 and the inner profile 24 are spaced apart from each other.

[0056] The insulator 430 consists of a first insulator part 432 and a second insulator part 434, which originally lie firmly against each other ( Figure 7). The insulator parts 432, 434 are designed to shrink upon reaching the threshold temperature at least in the direction normal to the longitudinal extension of the insulator 430 in such a way that over time an air gap 440 forms in the fire protection profile system ( Figure 8 ) . When the air gap 440 forms and the heat transfer due to radiation is forced into the outside of the fire protection profile system 420, the outside of the fire protection profile system 420 receives less heat from the fire source, 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 ).

[0057] 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.

[0058] Figure 10 to Figure 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 the 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 the air gap 540 runs in a zigzag shape along the longitudinal extension of the insulator 530. In Figure 11 the heat transfer layer or the air gap 640 runs triangularly along the longitudinal extension of the insulator 630. In Figure 12 the heat transfer layer or the 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 the air gap 840 runs trapezoidally along the longitudinal extension of the insulator 830.

[0059] The previously mentioned fire protection profile systems 20, 120, 220, 320, 420, 520, 620, 720, 820 according to the Figures 1 to 13are often powder-coated during production, whereby the fire protection profile systems 20, 120, 220, 320, 420, 520, 620, 720, 820 are often exposed to temperatures exceeding 150°C. Such fire protection profile systems include insulators or heat transfer layers with materials that can withstand the higher temperatures during powder coating. Therefore, in these embodiments, the aforementioned threshold temperature is greater than 200°C.

[0060] For the previously mentioned fire protection profile systems 20, 120, 220, 320, 420, 520, 620, 720, 820 according to the Figures 1 to 13 Without manufacturing steps involving elevated temperatures, materials with a threshold temperature greater than 90 °C can be used.

[0061] For the previously mentioned fire protection profile systems 20, 120, 220, 320, 420, 520, 620, 720, 820 according to the Figures 1 to 13Several coatings 50, 450, 550 can also be arranged on the insulators 30, 130, 230, 330, 430, 530, 630, 730, 830 or the heat transfer layers.

[0062] For the previously mentioned fire protection profile systems 20, 120, 220, 320, 420, 520, 620, 720, 820 according to the Figures 1 to 13 the outer profile 22 and the inner profile 24 can be open profiles, wherein the insulators 30, 130, 230, 330, 430, 530, 630, 730, 830 can extend at least partially into the outer profile 22 and the inner profile 24.

[0063] For the previously mentioned fire protection profile systems 120, 220, 320, 420, 520, 620, 720, 820 according to the Figures 1 to 13 the outer profile 22 and the inner profile 24 can be mechanically connected to one another with one or more connecting bolts 27, as in Figure 1disclosed. Alternatively, further connecting elements may be present in the fire protection profile systems 20, 120, 220, 320, 420, 520, 620, 720, 820 to mechanically connect the outer profile and the inner profile and, if necessary, to hold the insulators 30, 130, 230, 330, 430, 530, 630, 730, 830 in the fire protection profile system 20, 120, 220, 320, 420, 520, 620, 720, 820.

[0064] A manufacturing process of a fire protection profile system 20, 120, 220, 320, 420, 520, 620, 720, 820 according to the Figures 1 to 13 includes at least the following steps, although the order of the steps may vary: a.
