Abstract

The invention relates to a fireproof profile component (1), for the production of windows, doors, wall elements, facades and similar. Said component comprises two essentially U-shaped profile pieces, in particular made from extruded aluminium with an inner support shell (3) and an outer support shell (4) and which are connected to a composite profile (35), surrounding a single hollow chamber (H) at the free branch ends (300, 301, or 400, 401) thereof on the branch (5) of the U-shaped profile by means of thermally-separating insulating webs (6). The hollow chamber (H) is at least partly filled with a fireproof insulating mass (7). The particular advantage of said single-chamber composite profile with regard to fireproofing, is based on the fact that a large amount of fireproof insulating mass can be charged in the composite profile with the hollow chamber (H), thus forming a stable insulating block, in which the corner angles and connecting means can also be embedded. In conventional multi-chamber composite profiles this is not possible within the confines of the invention. Various production variants of the profile component (1) are disclosed, comprising amongst others, the user of a mortar-like hardening fireproof insulating mass (7), the use of pre-prepared insulating mass pieces and the recessing of unfilled partial chambers (37) in the hollow chamber (H).

Description

Fire-resistant profile component and method for its production

The invention relates to a fire-resistant profile component for the production of windows, doors, wall elements, facades and the like. Furthermore, the invention relates to a method for producing such a fire-resistant profile component.

EP 0 717 165 B1 describes a fire-retardant profile component which is manufactured as a multi-chamber profile from light metal, preferably from aluminum, with an insulating web which reduces the heat flow. In this framework, the outer and the inner shell each delimit a hollow chamber. These two hollow chambers are connected by means of an insulating web and embedded bridge webs, so that a three-chamber profile is formed. Fire protection panels are inserted into these chambers, which are fixed by means of metal springs. In the event of a fire, the fire protection panels release crystal water, which cools the aluminum profile and prevents the aluminum profile facing the fire from melting. The disadvantage of this construction is that it is only suitable for fire resistance times of up to 30 minutes. Higher fire resistance times of 60, 90 or 120 minutes cannot be achieved with this.

A frame system is also known from EP 0 785 334 B1, which is also manufactured from aluminum multi-chamber profiles. In this frame system, it is proposed that an aluminum core profile is formed in each case, which carries the fire protection glazing. Outer and inner shells are placed in front of this core profile, so that a three-chamber profile is also formed here. The load-bearing core profile or the two outer shells are connected to an insulating web that reduces the heat flow. The chamber of the core profile or the two hollow chambers of the outer shells are filled with fire protection insulating compound, so that the outer shells protect the load-bearing core of the aluminum profile in the event of a fire. DE 44 43 762 A1 discloses a fire protection element, in particular for building a framework on a building for holding a clampable component, such as fire protection glazing or a panel, which has a core profile, a heat-insulating filler material surrounding the core profile, and a casing surrounding the filler material and has an outer cover strip for clamping the component, the core profile, the filling compound and the casing forming a composite body. The framework is designed in such a way that light-metal profiles with a melting point lower than the temperature to be expected in the event of a fire and which affect the metal profiles can be used on the side facing the fire, the melting of these supporting light-metal profiles being prevented over a predetermined safety period. For this purpose, plates or moldings made of a heat-binding, hydrophilic adsorbent with a high water content are attached to the outside and / or on the inside of the metal profiles made of aluminum. In a preferred embodiment, the material of the plates or shaped bodies is a mixture of gypsum and alum, which has an energy-consuming effect when exposed to heat. When a response temperature is reached, the plates or moldings release crystal water, which cools the metal structure. The energy-consuming material can also be poured into the inner chamber of a metal profile in liquid form and then sets in the inner chamber to form a solid molded body.

The invention has for its object to provide a fire-resistant profile component that can be produced with less effort and a method for its production, the profile component being suitable for simple and inexpensive manufacture to withstand fire resistance times of 30, 60, 90 and 120 minutes.

The invention proposes that the profile component has a supporting inner and outer support shell, which by means of an insulating web, the z. B. is made of polyamide or PVC, is positively and positively connected, so that for normal use, ie not in the event of fire, a statically stable composite profile is formed. This composite profile surrounds a single hollow chamber which is partially filled with a fire protection insulating material at least in a core area. The fire-resistant profile component according to the invention is thus an advantageously thermally decoupled single-chamber composite profile.

According to the method according to the invention for producing the fire-resistant profile component, first two essentially U-shaped profile parts, in particular made of extruded aluminum, which form an inner support shell and an outer support shell, are connected at their free leg ends by means of thermally separating insulating webs to form a composite profile surrounding a single hollow chamber, and then the hollow chamber is partially filled with a fire protection insulating compound at least in an inner core area. Thus, at least the inner core area of the component according to the invention is connected to the support shells without separation, so that the cooling effect of the large inner filler volume can act directly on the outer walls of the support shell. Further subchambers of the hollow chamber enclosed by the support shells can either remain unfilled or can also be filled with heat insulation by the fire protection insulating material or in some other way.

The profile can be filled by inserting prefabricated molded parts or by filling in a mortar-like mass.

The fire protection insulation can, for. B. consist of a matrix of glass fiber reinforced mineral substances.

The fire protection protective effect of the profile component according to the invention results from the interaction of the individual components. In the event of a fire, the outer or inner aluminum support shell of the composite profile melts, depending on the location of the fire. The melting point of aluminum is 600-650 ° C. In a fire test according to DIN 4102, this temperature is reached after approx. 10 minutes in accordance with the ETK (standard temperature curve), after 30 minutes the temperature in the fire furnace is 822 ° C and after 90 minutes at 986 ° C. The insulating bars, which are made of a mechanically strong material with low thermal conductivity, prevent the heat from migrating to the aluminum tray on the side facing away from the fire. In the event of a fire, this aluminum carrier shell, together with the fire protection insulation, forms the statically supporting cross-section. It is particularly advantageous here that the frame system consists of one There is a single-chamber profile because the large hollow chamber allows the insulating compound to form a stable block together with the aluminum support shell on the side facing away from the fire, which then takes on the static load-bearing function.

In addition, it is advantageous here that the fire protection insulating composition has an insulating effect due to its composition, this insulating composition advantageously releasing crystalline water under the action of heat, as a result of which the entire profile component according to the invention is cooled and thus the fire resistance time is positively influenced.

Another possibility of controlling the fire resistance times is achieved by increasing or reducing the depth of the insulating webs and thus the distance between the aluminum outer and inner shells.

Another option is to change the depth of the inner or outer shells. In the event of a fire, it cannot be predicted from which side the fire will hit the profile component and the profile component with all anchorages, fittings, glass and panel brackets must ensure that the room is closed, all of these parts are on the outer and inner support shell of the aluminum composite profile attached.

The particular economic advantage of the single-chamber composite profile according to the invention is that the open, U-shaped aluminum inner and outer support shells are less expensive to produce than aluminum hollow profiles, and that there is the possibility of using metal corner angles to make the single-chamber composite profiles like normal thermally insulated Process aluminum profiles into frames and fill the fire protection insulation compound into the prefabricated frame through the large hollow chamber.

The particular fire protection advantage of the single-chamber composite profile according to the invention is that a large amount of fire protection insulating material can be filled into the single-chamber composite profile through the large hollow chamber, which forms a stable insulating block in which the corner brackets and connecting means can be embedded. To this extent this is not possible with multi-chamber composite profiles. It is also particularly advantageous if the fire-resistant component according to the invention is filled with a fire protection insulating compound which contains magnesium oxychloride cement or magnesium oxysulfate cement or consists entirely of magnesium oxychloride cement or magnesium oxysulfate cement.

Magnesium oxychloride cement is based on a patent that was granted to K. u. K. Privilege Archive was registered, and is called Sorelzement or Magnesiazement after its inventor. Mixtures of magnesium oxide (burned magnesia) and concentrated magnesium chloride solution harden like stones to form basic chlorides, the structure of which is derived from that of magnesium hydroxide, and have been used, for example, with the addition of neutral fillers and colors to produce artificial stones and seamless floors (see DIN 272 - magnesia screeds). and also from artificial ivory (billiard balls) (see Holleman-Wiberg, Textbook of inorganic chemistry, 81st-90th edition, pp. 685-686).

Due to the long popularity of Sorel cement, there is an extensive literature on this, which is controversial in some questions. It is known that magnesium oxychloride cement has heat and sound insulating properties. The cement has a high bulk density, which among other things has led to efforts to create pores in the sense of a lightweight construction. In addition, depending on its composition, the cement is also only partially water-resistant, so that despite its fire-retardant properties, it is only limited, i.e. e.g. has been used as a fire-retardant impregnating agent, not as a solid component. The high corrosiveness of the material also played a role. For example, magnesia screeds (also called magnesite screeds) are required to not come into contact with steel parts of buildings. Beams, frames and pipes must therefore be clad with bitumen paper or other barrier material before laying the screed.

Since the profile component according to the invention is a composite body which can also have a supporting function, a high bulk density of the cement has an advantageous effect. If necessary, however, a reduction in density can be advantageously achieved for profile components according to the invention which are used in particular in a non-load-bearing manner. Corrosiveness can be counteracted by, for example, applying a protective coat to the Inner walls of the hollow chamber applied or this is made of aluminum. A possibly less high water resistance than that of conventionally used material is insignificant due to the existing casing of the mass.

In the event of a fire, the mass does not come into contact with the fire at first, since it is surrounded by the wall of the hollow chamber, so that the fire resistance does not take effect immediately - as with components with a coating or impregnation with magnesium oxychloride cement - but only after a Melt the casing. Nevertheless, it has been shown that the fire-resistant profile component according to the invention surprisingly has increased fire resistance. This can be explained by the fact that the following reactions can take place during the production of a magnesium oxychloride cement:

A) 3 MgO + MgCl ₂ + 11 H ₂ O -> MgCl ₂ * 3 Mg (OH) ₂ * 8 H ₂ O

B) 5 MgO + MgCl ₂ + 13 H ₂ O -> MgCl ₂ * 5 Mg (OH) ₂ * 8 H ₂ O

C) 5 MgO + MgCl ₂ + 17 H ₂ O -> MgCl ₂ ^* 5 Mg (OH) ₂ * 12 H ₂ 0.

This shows that in the hardened cement crystal water is bound to a high degree in a matrix of magnesium chloride and magnesium hydroxide, so that due to the presence of hydroxides and oxide hydrates, the name magnesium oxychloride cement is completely rejected by some authors, while other authors defend this name , An exact elucidation of the structure is difficult and also results in different ways from the composition or the proportions of the raw materials used for the production. In any case, however, water is released or evaporated apparently like - and even more so than - with the known filler of gypsum and alum mentioned at the beginning with indirect heat (heat conduction through the wall of the casing), which with an endothermic reaction or with the absorption is associated with a high amount of latent heat and has a cooling effect on the casing. The high thermal conductivity of an aluminum material has a synergistic effect. With regard to an optimized property profile, it has proven to be particularly advantageous if the magnesium oxychloride cement has a composition with a molar ratio of MgCl ₂ / Mg (OH) ₂ / H ₂ 0 of 1: (2.5 to 5): (8 to 12 ) having.

A cement that is produced according to equation B) above and has particularly good mechanical properties has, for example, a molar ratio of MgCl ₂ / MgO / H ₂ O of 1: 5: 13 with a summary consideration of the chemically and that bound in the crystal Water on - or a molar ratio of MgCI ₂ / Mg (OH) ₂ / H ₂ 0 of 1: 5: 8 with individual consideration of the chemically and the water bound in the crystal.

The filler of the magnesium oxychloride cement can also be made with the addition of magnesium sulfate, whereby it can consist of a matrix in which Mg (OH) ₂ -, MgCl ₂ -, MgSO ₄ -, Mg _x OCI -, Mg _y OSO ₄ - and Mg _z CIS0 ₄ molecules or ions are contained, which can have an advantageous effect on increased water retention and on the water resistance of the cement. (The indices x, y, z can assume integer or non-integer values.) It has proven to be particularly advantageous here if the magnesium oxychloride-magnesium oxysulfate cement formed by admixing magnesium sulfate has a composition with a molar ratio of MgCl ₂ / MgSO ₄ of 1: (0.02 to 1.9).

In the case of the formation of magnesium oxysulfate cement, the following chemical reaction equations are used:

D) MgO + 2 MgSO ₄ + 4 H ₂ O -> 2 MgS0 ₄ * Mg (OH) ₂ * 3 H ₂ 0

E) MgO + MgSO ₄ + 6 H ₂ O -> MgS0 ₄ * Mg (OH) ₂ * 5 H ₂ O

F) 3 MgO + MgSO ₄ + 11 H ₂ O -> MgSO ₄ * 3 Mg (OH) ₂ * 8 H ₂ 0

G) 5 MgO + MgSO ₄ + 8 H ₂ O -> MgS0 ₄ * 5 Mg (OH) ₂ * 3 H ₂ 0,

however, only a cement produced according to equation F) is considered to be chemically stable at room temperature. Such a magnesium oxysulfate cement used in a fire protection element according to the invention can advantageously have a composition with a molar ratio MgSO ₄ / Mg (OH) ₂ / H ₂ O of 1: (2.5 to 3.5): (6 to 10) , The filler of a magnesium oxysulfate cement can also be made with the addition of magnesium chloride. In this case too, a matrix with a qualitative composition can be formed, as described above for a magnesium oxychloride cement when magnesium sulfate is added. An advantageous composition is a MgSO / MgCl ₂ molar ratio of 1: (0.02 to 1.9). A filling compound with a low chloride content is less corrosive than a filling compound with a high chloride content.

In the following, a mixed cement which is formed from magnesium chloride and magnesium sulfate is referred to as a magnesium oxychloride-magnesium oxysulfate cement if the proportion of magnesium chloride in the preparation of the composition is higher than the proportion of magnesium sulfate, and of a magnesium oxysulfate-magnesium oxychloride cement if the situation is reversed. With increasing sulfate content, the water resistance increases on the one hand, but on the other hand the mechanical stability of the cement also decreases.

When preparing the filling compound formulation (determining the gravimetric weighting ratios), the purity of the raw materials used or crystal water contained in the salts must be taken into account from the outset.

Further improvements in properties of the fire-resistant profile component according to the invention can also be achieved in that the fire protection insulating composition contains water glass, in particular sodium water glass, and / or silica, in particular in gel form, the latter in a particularly advantageous manner initially by precipitation with metal salt and / or acid from the filling compound Water glass (in aqueous solution) can be produced.

Further advantageous embodiments result from the subclaims.

In the different figures of the drawings, the same or functionally corresponding parts are always provided with the same reference numerals, so that a multiple description of the individual versions is largely dispensed with below.

In FIG. 1, a cross section through a fixed glazing made of fire-resistant profile components 1 is shown by way of example, where I denotes the inside and A the outside. The fixed glazing consists of sections of the profile components 1 and fire protection glazing 2 which are joined together to form a frame R (cf. FIG. 6). The profile component 1 consists of an essentially U-shaped inner support shell 3 and a likewise substantially U-shaped outer support shell 4 which are made, for example, of extruded aluminum and enclose at least one inner core region 4a. The inner and outer support shells 3, 4 face each other with their side legs 5 and point in the direction of the inner side 1 and outer side A. In the side legs 5 of the inner and outer support shells 3, 4 extending transversely to the window plane XX there are undercut grooves 302, 402 attached in the region of the free ends 300, 301, 400, 401 of the side legs 5, which take up the thermally separating insulating webs 6 by rolling them up in a non-positive and positive manner. The insulating webs 6 have the property that they are poorly heat-conducting and melt under the influence of heat. The profile component 1, which forms a single-chamber aluminum composite profile 35 with the inner support shell 3 and outer support shell 4 and the insulating webs 6, encloses a single hollow chamber H which is filled with a fire protection insulating compound 7. The fire protection insulating compound 7 is connected to the inner support shell 3 and outer support shell 4 in a form-fitting or form-fitting and non-positive manner (via adhesive forces between the fire protection insulating compound 7 and the carrier shells 3, 4). The insulating webs 6 and the side legs 5 of the inner and outer support shell 3, 4 can be made at different depths across the XX axis; this allows the fire resistance duration to be controlled. The fact that, according to the invention, there are no transverse walls delimiting the support shells 3, 4 between the inner support shell 3 or the outer support shell 4 and the inner core region 4a of the profile component 1, as in the case of an object according to the known prior art (DE 93 21 360 U1) causes no heat supply in the core area 4a, which could consume the cooling capacity of the insulating compound 7. Nor can such transverse walls be cooled differently from the rest of the profile, which would lead to distortion of the profile component 1 when heated in the event of a fire. The fire protection insulating compound 7 consists of a material which, when a supporting shell 3 or 4 melts, protects the opposite supporting shell 3 or 4 from the exceeding of the temperatures which are specified according to the standards. This is achieved in that the insulating compound 7 is located as an insulating block in front of the inner or outer supporting shell 3 or 4 facing away from the fire and the fire protective insulating compound 7 releases crystalline water under the action of heat, so that the entire supporting profile 3 or 4 is cooled together with the fire protective insulating compound 7. In addition, to improve the load-bearing capacity, a metallic wire mesh 8 can be inserted into the fire protection insulating compound 7 as a moning.

For normal cases (not fire cases), glazing 2 formed from fire protection glass is held in a known manner in that profile component 1 formed has an approximately L-shaped cross section with a glass abutment 9 parallel to the XX axis, into which a groove 405 is received the outer glass seal 10 is molded. On the inside I of the profile component 1, the fire protection glass 2 is held by a glass strip 11, which is inserted into a groove provided in a side leg 5 of the inner support shell 3 and fixed by an inner glass seal 12. In the event of a fire, however, the fire protection glass 2 is held by metallic molded parts 13, which are preferably used as pieces of stainless steel. Since it cannot be determined in advance whether the fire will strike the inner or outer support shell 3 or 4, the metallic molded part 13 must be fastened to the inner support shell 3 and the outer support shell 4 by means of screws (the screws are not shown here). The metallic molded parts 13 can have a width of 2 to 5 cm. The distance between the molded parts can be between 20 and 100 cm. The higher the fire resistance duration, the smaller the distance. The thickness of the molded part 13 is between 0.5 and 2 mm.

In order to prevent the passage of hot fire gases between the end face of the fire protection glass 2 and the inner support shell 3 and the outer support shell 4, a seal 14 foaming under the action of heat is inserted into the glass rebate.

The above-described basic structural features of a fire-retardant or fire-resistant profile component 1 according to the invention for Formation of frames are common to all profile components according to the invention shown in Figures 1 to 6, the same parts being provided with the same reference numerals. Here, however, the individual profile components according to the invention from FIGS. 1 to 5 have further functions as fixed glazing frame profile, door frame profile, door sash profile, window frame profile, window sash profile or due to special requirements in the gap area between the door frame profile and the Door sash profile or special configurations between two door sash profiles as well as window frame profile and window sash profile.

In Figure 2, a frame 15 is shown together with a sash 16 on the lock side of a single-leaf door, between which a circumferential folding chamber F is formed. The door lock 17 in the casement 16 is fastened to the inner and outer support shell 3, 4 by means of a connecting bracket 18 by means of screws. Likewise, the striking plate 19 is fastened to the frame 15 with a connecting strap 18 on the inner and outer support shell 3, 4. The anchor member 20 is respectively attached to the same frame 15 by means of screws at the inner ^"and outer supporting shell 3 4.

Basically, according to the invention, all fitting parts that are required for locking the door, as well as all fastening and anchor parts are always fastened to the inner and outer support shells 3 and 4 in order to independently of the fire side, the closure and the statically flawless fastening of the profile component which the frame 15 and sash 16 is made to ensure.

In FIG. 2a, the rebate area between the casement 16 and the frame 15 with the rebate chamber F is shown again. Here, the cut does not run through the lock area of the door, but above or below the door lock 17. In the side legs 5 of the inner and outer support shells 3 and 4 of the frame 15 and the sash 16, grooves 303, 304, 403, 404 are formed, which advantageously incorporate a foaming seal 14 under the action of heat in order to prevent the passage of hot combustion gases. In addition, a stop leg 21 is formed on the frame 15 on the inner support shell 3 and on the casement 16 on the outer support shell 4, each parallel to the XX axis. The stop leg 21 has a molded one Groove 21a for receiving a stop seal 22, which ensures that the door is windproof.

FIG. 3 shows the area of a middle cuff of a two-leaf door with two jambs of leaf frames 16 and 23 lying next to one another. The sash frame 16 with the door lock 17 corresponds to the embodiment according to FIG. 2, the post of the sash frame or sash 23 contains a guide tube 24 made of plastic or metal in the center of the fire protection insulating mass 7 for receiving a locking bar 25. The locking bar 25 is used in connection with the driving bolt lock 26 for locking the sash frame 23. Advantageously, the guide tube 24 is located in the center of the fire protection insulating compound 7 and thus approximately in the neutral bending zone, so that if the sash frame 23 is strongly deflected, which occurs in the event of a fire, the fire protection insulating compound 7 does not have additional stresses is loaded, which can lead to the bursting of the block from the fire insulation 7. Analogously, the guide tube 24 with the locking bar 25 can also be in the casement 16 for additional locking, e.g. a door active leaf can be used.

FIG. 4 shows a framework which corresponds to the structure of FIG. 2. However, the profile design is advantageously designed so that the framework can be used as an open window of fire protection class F30, F60 and F90 in an outer facade. Since high demands are made of wind and rainproofness on window constructions in the outside area, the profile formation is advantageously designed in such a way that the rebate space between the window frame 27 and the window casement 28 is enlarged in the area of the respective outer shell 4, so that in a receiving groove 29a in the side leg of the outer shell 4 of the window frame 27, a central web seal 29 can be clamped, which rests with its upper lip against a stop edge of the outer shell 4 of the window casement 28 and thus ensures wind and rainproofness. When water enters the dewatering chamber 31, the water is conducted outward again through the drainage bore 32. The drainage hole 32 is covered in a known manner with a rain cap 30. The fitting installation, the glass holder and the anchorages are carried out as described in FIG. 2. FIG. 5 shows an alternative holder for the fire protection glass 2. Here, the glass edge of the fire protection glass 2 is additionally protected by a continuous metal holding strip 33 after the outer supporting shell 4 or the inner glass strip 11 has melted. The metallic retaining strip has a U-shaped cross-sectional configuration with two side legs 33a and a bottom leg 33b connecting them. The side legs 33a are formed with a continuous hollow chamber, for. B. made of appropriate steel pipes. The side legs 33a are fastened to the bottom leg 33b by means of screws (not shown here). The bottom leg 33b is about 2 to 5 cm wide and is attached at a distance of about 20 to 100 cm. The thickness of the bottom leg 33b is approximately 2 to 5 mm. The distance and the number of base legs 33b depend on the fire resistance duration. The bottom legs 33b are each fastened by screws to the side legs 5 of the aluminum inner and outer support shells 3, 4. According to the invention, this glass holder ensures that, regardless of the direction of the fire, the additional glass holder is always attached to a support shell 3 or 4 facing away from the fire.

FIG. 6 schematically shows the production of a frame R, as can be used, for example, for the construction of the window frames and / or casement frames used in the figures explained above to form windows, doors, wall elements, facades and the like. For this purpose, profile components with the above-described construction of essentially U-shaped profile parts made of extruded aluminum, each of which form an inner support shell 3 and an outer support shell 4 and at their free leg ends by means of thermally separating insulating webs 6 to form a composite profile 35 surrounding a single hollow chamber H. prefabricated and cut to length to individual frame sections, which are identified in FIG. 6 by reference numbers R1, R2, R3 and R4. Then these miter-cut frame sections R1 to R4 are combined to form the frame R shown in FIG. 6, it being possible here to use corner connectors in known embodiments in the corner areas between the individual sections R1 to R4. Now at least one, but advantageously two, with the reference numerals B, E in the frame section R4, is bored into the frame R formed in this way, into the hollow chamber surrounded by the composite profile 35 H, see Figure 1, rich (t) / (en). It is now possible to fill a liquid or plastic fire protection insulating compound 7 according to arrow P1 through the bore B into the hollow chamber H, the air contained in the hollow chamber H being able to escape via the second bore E according to arrow P2. When the hollow chamber H is completely filled with the fire protection insulating material 7, the bores B, E are closed by means of suitable closure elements and the fire protection insulating material 7 hardens within the frame R. Alternatively, as already mentioned, it is possible for the fire protection insulating material 7 to be introduced, at least partially, as one or more molded part (s) which is adapted to the entire or a partial cross section of the hollow chamber H, which is illustrated in the drawing by means of the reference symbol 36 ,

In the event that the frame is composed of the frame sections R1 to R4 in such a way that the hollow chamber H surrounded by the composite profile 35 in the respective frame sections R1 to R4 is continuously and continuously guided through the entire frame R, a single insertion is sufficient Bore B or from two bores B, E in the frame R in order to be able to fill the entire circumferential hollow chamber H with fire protection insulating compound 7.

If, however, which is preferred for reasons of stability, corner connectors are used in the transition areas between adjacent frame sections R1, R2, R3, R4, for each frame section R1 to R4 there is in each case a hole B for filling in the fire protection insulating material 7 and a hole E in each case introduced to escape the air contained and thus each frame section R1 to R4 of the frame R separately filled with the fire protection insulating material 7.

A major advantage of the method described above is that the profile sections are cut to length before they are filled with the fire protection insulating material 7. Since in this case only aluminum (the outer and inner support shell 3, 4) and plastic (the insulating webs 6) have to be severed, this can be carried out on conventional sawing devices without great effort and wear. Filling with fire protection insulating material 7, which has already been carried out at this time, on the other hand, due to the additional fire protection insulating material 7 to be cut, causes a very high level of saw wear, which is avoided according to the invention. FIG. 7 essentially corresponds to FIG. 1. Here, however, before the profiles are filled with fire protection insulating material 7, at least one molded part (not shown) is inserted into the aluminum support shells 3, 4, which is removed from the profile component 1 after the fire protection insulating material 7 has been filled and hardened can be pulled out, so that at least one partial chamber (s) 37 not filled with fire protection insulating compound 7 remain in the single hollow chamber H. This method has the advantage that the profiles on the rod can be filled and the unfilled partial chambers 37 can be used to connect the profiles with a corner bracket (corner connector).

FIG. 8 essentially corresponds to FIG. 2. Here, too, there is in each case in the single hollow chamber H - in addition to in this case two core areas 4a filled with fire protection insulating material 7 in each hollow chamber H - at least one (again in the hollow case H shown in each case two) Partial chamber (s) 37 not filled with fire protection insulating compound 7 are provided. In addition, in the middle of the profile component 1, e.g. Insulation 38, 38a consisting essentially of mineral wool is used. This thermal insulation 38, 38a serves the purpose that when the profile components 1 are used in an outside area, in addition to fire resistance, a good heat-insulating effect of the profile component 1 can also be achieved. Optionally, the fire protection insulating compound 7 - as shown - can also be reinforced with a reinforcement 39. Thermal insulation 38, 38a and / or reinforcement 39 can of course also be provided regardless of the presence of unfilled partial chambers 37. The aforementioned manufacturing advantages also come into play in this embodiment.

In the embodiment shown, the thermal insulation 38a is constructed as a sandwich panel, the large walls of which are formed from glass fiber fabric mats dipped in fire protection insulating material 7. This results in better handling for the introduction of the thermal insulation, since this sandwich panel can be easily inserted.

FIG. 9 illustrates two further possibilities in order to achieve that in the single hollow chamber H, partial chambers not filled with fire protection insulating material 7 mer (n) 37 remain. In the upper part of FIG. 9, an adhesive tape 40 is glued into the profile component 1. The adhesive tape 40 closes the filled part of the hollow chamber H against the unfilled part chamber 37. The adhesive tape 40 is glued in before the inner carrier shell 3 and the outer carrier shell 4 are connected by the insulating webs 6 and before the profile component 1 is filled with fire protection insulating compound 7. The adhesive tape 40 prevents the partial chamber 37 from being filled with fire protection insulating compound 7. After the filling, the adhesive tape 40 remains in the profile. The adhesive tape 40 is preferably glued with two legs 41, 42 of the inner carrier shell 3 protruding into the hollow chamber H and opposite one another at a distance L, and bridges the distance L between the legs 41, 42. In particular, the adhesive tape 40 is in each case on the side walls of the legs 41, 42 which face the part of the hollow chamber H which is filled with fire protection insulating material 7 or which is initially to be filled. As a result, it cannot loosen under the pressure of the fire protection insulating compound 7 during filling, but is pressed even more firmly. An adhesive tape 40 could of course also be provided analogously on the outer support shell 4.

In the lower part of FIG. 9, a molded plastic body 45 is pushed over two legs 43, 44 of the outer supporting shell 4 that are opposite one another at a distance L. The molded plastic body 45 closes off the filled part of the hollow chamber H against the unfilled part chamber 37. The molded plastic body 45 is pushed on before or after the connection of the inner support shell 3 and the outer support shell 4 by the insulating webs 6, but in any case before the profile component 1 is filled with fire protection insulating material 7, as a result of which the distance L between the legs 43, 44 is bridged , The molded plastic body 45 prevents the partial chamber 37 from being filled with fire protection insulating compound 7. After filling, it remains in the profile. So that the plastic molded body 45 cannot loosen under the pressure of the fire protection insulating compound 7 during filling, it positively embraces the free ends of the legs 43, 44. For this purpose, a groove 406 is provided on each of the two long sides of the molded body 45. A molded plastic body 45 could of course also be provided analogously on the inner support shell 3. If non-filled partial chambers 37 are present in the profile component 1, it is important that the fire protection insulating compound 7 is in any case filled in such a way that the free leg ends 300, 301 400, 401 of the support shells 3, 4 are fully absorbed in the fire protection insulating compound 7, as is the case here is shown in Fig. 7, wherein the fire protection insulating material 7 can expediently extend even further outwards.

As already explained, the fire protection insulating compound 7 can preferably be wholly or partly a magnesium oxychloride cement or a magnesium oxysulfate cement, which may optionally also additionally contain magnesium sulfate or magnesium chloride. As already mentioned, this feature and the compositions given above, which derive from the stoichiometry of the reactions taking place in the setting, are likewise given inventive importance.

To achieve the desired properties, it is necessary that the specified minimum amount of magnesium chloride in the ratios MgCl ₂ / Mg (OH) ₂ / H ₂ O of 1: (2.5 to 5): (8 to 12) and MgCl ₂ / MgSO ₄ of 1: (0.02 to 1.9) is not fallen below, since, on the contrary, there can be a considerable drop in fire resistance compared to the maximum achievable value according to the invention.

In the case of the production of magnesium oxychloride-magnesium oxysulfate cement, however, part of the magnesium chloride used to manufacture the fire protection insulating material 7 can be replaced by a metal chloride, such as calcium chloride, the cation of which forms sparingly soluble sulfates. A sedimentation reaction according to the equation runs during the production of the insulating compound 7

CaCI ₂ + MgSO ₄ -> MgCI ₂ + CaSO ₄ ,

from where the magnesium chloride is formed in the manufacturing process itself from the other metal chloride. The precipitated sparingly soluble metal sulfate, in the illustrated case gypsum, can on the one hand only in the hardened insulating compound 7 act in the sense of a filler, but on the other hand advantageously also contribute to a further improvement in properties.

If the fire protection insulating material 7 contains water glass, in particular sodium water glass, this results in greater strength and water resistance and in an increased fire resistance of the material. In particular, it has proven to be advantageous if the sodium water glass has a composition with an average molar Na ₂ O / SiO ₂ ratio of 1: (1.5 to 4.0) and if the sodium water glass is initially liquid in the insulating compound 7 is introduced, it should have a density of about 1.32 to 1.55 g / cm ³ . The amount of water glass introduced into the insulating compound 7 should be selected such that the magnesium oxychloride cement, magnesium oxysulfate cement or magnesium oxychloride-magnesium oxysulfate cement has a composition with an average molar ratio of MgCl ₂ (or MgSO, in the case of a magnesium oxysulfate ₎ - Cement) to soda water glass of about 1: (0.02 to 0.35).

It has also already been stated that it is advantageous if the insulating compound contains 7 silica. This can e.g. can be added as an amorphous powder. The presence of silica in the insulating compound 7 brings about improvements in properties similar to those of the water glass, but it increases its effectiveness.

As is known, silica is a collective name for compounds that can contain silicon dioxide and different proportions of water. A distinction is made between orthosilicic acid, different types of polysilicic acids and metasilicic acids and finally the so-called phyllodic silicic acid, whereby the silicas mentioned are characterized by an increasing degree of condensation and decreasing water content in the order given and in the final stage of the condensation which takes place with the formation of chain molecules, almost anhydrous silicon dioxide is formed.

Silicic acid can be produced from water glass by precipitation using metal salt and / or acid, whereby it is initially present as a (liquid) hydrosol with a low degree of condensation and at a corresponding temperature (starting at room temperature or slightly above) and at a corresponding pH value (larger or less than about 3.1-3.3) an envelope of the colloidally disperse silica Acid particles used, which can lead to gel formation. In such a (solidified) gel, the silica is arranged in a reticulated and / or honeycomb-like structure with a high specific surface area and porosity in the water. The fact of the sol-gel reaction can be exploited according to the invention in that the silica is generated by precipitation using metal salt and / or acid from water glass initially contained in the insulating compound 7. This advantageously results on the one hand in an increase in strength and fire resistance, and on the other hand also reduces the amount of shrinkage of the hardening insulating compound 7.

The fire protection insulating material 7 is - as stated - introduced into the hollow chamber H in the flowable state. For the production of a magnesium oxychloride cement, a fire protection insulating compound 7 is preferably used, which is produced from a mixture of magnesium oxide (reactively fired magnesia) and concentrated, in particular saturated or supersaturated, aqueous magnesium chloride solution and can also be produced with the addition of magnesium sulfate. In the latter case, it is also possible to add a metal chloride, such as calcium chloride, the cation of which forms poorly soluble sulfates, such as calcium sulfate. To produce a magnesium oxysulfate cement, an insulating compound 7 with concentrated, in particular saturated or supersaturated, aqueous magnesium sulfate solution is used in an analogous manner.

The insulating compound 7 can furthermore be produced with the addition of water glass, in particular sodium water glass in liquid solution, preferably two partial mixtures, one from the starting materials mentioned for the magnesium oxychloride cement or magnesium oxysulfate cement and another from the water glass, optionally mixed with Magnesium sulfate or magnesium chloride, are stirred into a highly viscous suspension.

The insulating compound 7 can also contain silica, which is preferably produced in the manufacturing process of the insulating compound 7 by precipitation from water glass by means of acid or salt. Mineral and / or organic acids can be used to set a suitable pH. An insulating compound 7, which is produced from a mixture of 35 ± 25% by mass of MgCl ₂ , 13 ± 12% by mass of MgSO ₄ , 35 ± 25% by mass of MgO and 5.1 ± 5.0% by mass of water glass, has proven particularly useful, with the proportion of aqueous water glass solution optionally the acid used for the reaction with the water glass can be contained.

With the invention, as already mentioned above, a fire resistance class of up to F120 can be achieved. The invention is not limited to the various exemplary embodiments shown, but also includes all equivalent designs. For example, the person skilled in the art can In addition, provide further advantageous measures, such as the addition of fillers or pigments to the fire protection insulating material 7, zinc oxide, titanium oxide and aluminum oxide being particularly suitable for this. Embedding reinforcing parts or materials, such as glass fibers or a woven fabric made of plastic, wire, glass fibers or the like, in the fire protection insulating compound 7 can also be provided as a measure which reinforces the advantages of the invention.

Finally, a recipe of the following composition has also proven to be particularly advantageous for producing a fire protection insulating composition 7 according to the invention:

13 ± 12 mass percent MgCl ₂ , 31 + 30 mass percent MgSO ₄ , 31 + 30 mass percent MgO and 5.1 + 5.0 mass percent water glass, with a proportion of 1 to 30 percent by volume hollow microspheres being provided as filler.

The hollow microspheres are in particular functional lightweight fillers known per se, which can be produced in particular on a glass or ceramic basis, for example on a silicate basis with SiO ₂ , Al ₂ O ₃ as constituents, optionally containing boron, with a density from 0.7 to 0.8 g / cm ^{3 can have} a bulk density of 380 to 420 g / l and whose grain size can advantageously extend over a range from 10 μm to 2000 μm, preferably from 80 μm to 1000 μm. The use of hollow microspheres with a temperature resistance of up to 1600 ° C. and a compressive strength of over 23 MPa, for example of 28 MPa, is particularly advantageous.

With regard to the composition of the fire protection insulating material 7, the following four recipes are given as examples, with which in an inventive according to the fire protection element without exception at least fire resistance class F 30 according to DIN 4102, partly a fire resistance class F 120, has been achieved:

In a further (fifth) formulation of the fire protection insulating material 7, the proportion of magnesium sulfate was replaced by magnesium chloride based on example 1 and in a sixth formulation based on example 3, the proportion of magnesium chloride was replaced by magnesium sulfate. With this, too, fire resistance class F 30 according to DIN 4102 was achieved in a fire protection element according to the invention without exception.

Furthermore, the invention is not limited to the combinations of features defined in the independent claims, but can also be defined by any other combination of certain features of all the individual features disclosed overall. This means that basically every single feature of the independent claims can be omitted or replaced by at least one individual feature disclosed elsewhere in the application. In this respect, the independent claims are only to be understood as a first attempt at formulating an invention.
