EP3450671B1 - Method for producing fire protection termination elements with and without glazing and fire protection termination element and fire protection termination element series - Google Patents

Description

The invention relates to a method for producing fire protection closure elements. Fire protection closing elements are, for example, a door, a door leaf, a frame or fixed glazing in fire protection design. The invention further relates to a fire protection closure element that can be produced therewith and a fire protection closure element series that can be produced therewith, ie a production series of fire protection closure elements.

Fire and smoke protection tube frame elements are known, for example, from the company brochure "Fire and smoke protection tube frame elements" from Hörmann KG Vertriebsgesellschaft with the print note "Stand 04.2017/Print 04.2017/HF84563DE. They have a frame made of metal profiles that enclose a cavity Frame can be filled with filling elements such as fire-resistant glass panes.

Light metals such as aluminum or aluminum alloys or steel are particularly suitable as materials for the metals. The metal profiles are usually made up of several half-shells, which are connected to one another by insulating bars in order to avoid heat transfer.

In order to form tubular frame elements of this type for suitability in fire protection closures, fire protection materials are introduced into cavities in the metal profiles. For this purpose, panels made of fire protection materials, such as calcium silicate panels or gypsum panels, are cut into bars, for example, with the bars then being pushed into the metal profiles.

Such methods for producing metal profile frames are in DE 10 201 419 A or the EP 1 793 073 A2 or the aforementioned company publication.

The previously known methods are very complex in terms of assembly.

In order to avoid the installation effort, at least for fire protection closures with a lower fire protection class, DE 10 2005 014 544 A1 also been proposed to provide one of the cavities of the respective metal profile with a strip of intumescent material that is only activated in case of fire.

In particular, the invention also relates to the production of fire protection closure elements, as known from the company brochure "Functional doors for your house" from Hörmann KG Vertriebsgesellschaft with the print note as of 03.2017/print 03.2017/HF 85115 DE/PDF. Another example of fire protection closures, as they can represent an embodiment of the invention, are fire protection doors, such as those from the company publication "Steel and stainless steel sliding doors FST" from Hörmann KG Vertriebsgesellschaft with the print note as of 08.2016/print 08.2016/HF 86038 DE/PDF are known.

Such fire protection closing elements in the form of wings or frame elements of fire protection gates or fire protection doors, in particular in a box-lid design, have a jacket that encloses a cavity into which a fire protection mat is inserted.

Conventional fire protection mats for these purposes are made of mineral fibers. There are, for example, glass fiber mats or rock wool mats on the market for this purpose. The prior art is this also on the EP 1 533 462 A2 and the prior art cited therein and the WO 2002/8557 A1 referred.

Fire protection mats based on mineral fibers are complex to manufacture and difficult to handle. In particular, cutting such fire protection mats to size is difficult. Therefore, such fire protection mats often have to be kept in stock for different sizes of fire protection closure elements in different sizes.

From the DE 201 14 949 U1 and the EP 1 296 013 A1 a fire-resistant profile component for the production of windows, doors, wall elements, facades and the like is known, which has two essentially U-shaped profile parts made of extruded aluminum, which are connected by means of insulating bars, with a cavity between them being filled with a fire protection insulating compound. The fire protection insulating compound is made of magnesium oxychloride cement. However, the fire protection insulating compound can also contain water glass or silicic acid in gel form. Thus, these publications disclose a fire protection closure element comprising at least one fire protection glass pane and a frame in which the at least fire protection glass pane is held, the fire protection glass pane having at least a first glass pane and a second glass pane with a fire protection glass pane cavity in between.

From the DE 10 2015 108 567 A1 a fire protection door or a fire protection gate in a box-cover design with a fire-retardant filling is known. The fire protection device has a reservoir of a non-combustible liquid that is arranged in the upper area of the fire protection device and is bound as a gel.

From the DE 100 03 856 A1 a fire protection mat is known which is divided into segments which are sealed against one another. The segments are filled with fire retardant, which mainly contains aqueous sodium silicate, possibly mixed with fibers such as glass fibers. The fire protection material can be in the form of pellets, tablets, powdered or in the form of a gel.

From the U.S.A. 4,223,175 the use of film tubes filled with liquid in the form of water for fire protection of cable lines is known.

Also from the US2016/107010 A1 a foil packaging with yellow filling for fire protection purposes is known.

the DE 20 2009 015 497 U1 relates to the filling of a cavity in a box-cover plate fire-resistant door leaf using metal foils.

From the EP 0 705 685 A1 a fire-resistant glass unit with two panes and a fire-resistant glass cavity is known, which is filled with an intermediate layer that foams up in the event of a fire. The intermediate layer consists of soda water glass, water, organic substances that increase the resistance time in the event of a fire, and potash water glass.

the DE 10 2009 044 796 A1 a fire protection glass, an all-glass fire protection door and a method for their production is known. The fire-resistant glass has only two panes of glass. A fire protection material is provided in a fire protection glass cavity between the glass panes. Nothing further is stated about the type of fire protection material.

In the manufacture of glazed doors and fixed glazing, it is currently envisaged that manufacturers of the doors and frames for the fixed glazing will manufacture the frames and purchase fire-resistant glass filled with fire-resistant gel from a manufacturer of fire-resistant glasses. In order to make the frames or other door leaves fire-resistant, additional fire protection materials are procured that have to be pre-assembled according to the size of the cavity to be filled. This requires complicated supply chains and correspondingly complicated warehousing for the different fillings.

The object of the invention is to simplify the production of fire protection closure elements with and without glazing. In particular, a method for the simplified series production of fire protection closure elements of different designs is to be proposed.

This object is achieved by a method according to claim 1. A fire protection closure element that can be produced with it and a fire protection closure element series that can be produced with it in series production are the subject matter of the secondary claims. Advantageous configurations are the subject matter of the dependent claims.

1. a) Bereitstellen von Brandschutzglasscheiben für Feuerschutzabschlusselemente mit Verglasung, wobei die Brandschutzglasscheiben wenigstens eine erste Glasscheibe und eine zweite Glasscheibe mit einem Brandschutzglasscheiben-Hohlraum dazwischen aufweisen,
2. b) Füllen des Brandschutzglasscheiben-Hohlraums mit einem zum Befüllen von Brandschutzglasscheiben geeigneten Brandschutzgel, vorzugsweise derart, dass die befüllten Brandschutzglasscheiben glasklar durchsichtig sind;
3. c) Bereitstellen eines Feuerschutzabschlusselementkörpers mit einem Feuerschutzabschlusselement-Hohlraum; und
4. d) Füllen des Feuerschutzabschlusselement-Hohlraums mit dem gleichen Brandschutzgel.

According to a first aspect, the invention provides a method for producing fire protection closure elements with glazing or for producing fire protection closure elements with glazing and fire protection closure elements without glazing, with the steps:

1. a) providing fire-resistant glass panes for fire-resistant closure elements with glazing, the fire-resistant glass panes having at least a first glass pane and a second glass pane with a fire-resistant glass pane cavity in between,
2. b) filling the fire-resistant glass pane cavity with a fire-resistant gel suitable for filling fire-resistant glass panes, preferably in such a way that the filled fire-resistant glass panes are crystal-clear;
3. c) providing a fire barrier body having a fire barrier cavity; and
4. d) filling the fire barrier cavity with the same fire barrier gel.

A basic idea of the invention is to proceed in the manufacture of the fire protection closure elements in such a way that the fire protection glass panes are filled and that at least one cavity in other areas of the fire protection closure elements is also filled with the same fire protection gel with which the fire protection glass panes are filled.

The fire-resistant glass panes are preferably no longer procured and stored as a prefabricated and already assembled unit, but rather as part of the production of fire-resistant closure elements Glass panes, spacer frames and fireproofing liquid to form the infill made of fireproofing gel.

As a result, fewer and less complex deliveries and a smaller number of different materials are required. The filling of cavities in bodies of fire protection closing elements, such as metal profiles, cavities in door leaves, in particular between the box plate and cover plate, or in fire protection doors with fire protection gel has other advantages, which are explained in more detail below.

As part of the provision of the fire protection closure element body, a method for producing metal profile frames for fire protection closure elements is preferably carried out, which is less complex than the previous production of metal profile frames for fire protection closure elements. Advantageously, a higher fire protection class should also be achievable with little effort.

It is preferred that a hydrogel containing salt is used as the fire protection gel.

A metal profile frame for the fire protection closure element can thus be produced by embodiments of the invention for the production of a fire protection closure element, with at least one metal profile which has at least one cavity filled with the fire protection gel. In which Metal profile frame is preferably held a fire protection glass pane, which is filled with the same fire protection gel.

A fire protection closing element can be produced by configurations of the invention, which comprises such a metal profile frame.

The invention relates to the use of the same fire protection gel both as a fire protection material in cavities in frames or door leaves or other fire protection closure elements, whether glazed or not, and as a filling in fire protection glass panes of glazed fire protection closure elements. According to the invention, a fire protection gel that is suitable for filling fire-resistant glass panes—including its optical properties—or a fire protection liquid that forms a fire protection gel that is suitable for filling fire-resistant glass panes is used to fill a cavity in a metal profile.

“Fire protection gel” is understood to be a gel that is suitable for filling fire protection glass panes and has a cooling effect when exposed to the heat that occurs in the event of a fire, and in particular releases evaporating water or causes a chemical reaction that consumes heat energy. In particular, the fire protection gel as a filling in the fire protection glass pane is transparent, so that the fire protection glass pane filled with it offers the same or essentially the same view through as a normal glass pane. Suitable fire protection gels are specified, for example, in the following references, with express reference being made to each individual one for further details regarding the possible composition and the possible production of the fire protection gel or the fire protection liquid forming the fire protection gel:

• DE 35 30 968 A1
• DE 101 47 401 A1
• DE 102 37 395 B4
• DE 197 31 416 C1

• DE 10 2005 018 842 A1
• WO 03/061963 A1
• WO 2014/190444 A1 .

These references each deal with fire-resistant glazing that is formed from at least two panes of glass that have a cavity between them. This cavity is filled with a fire protection gel. The fire protection gel composition for the fire protection glasses is explained in more detail in the individual references mentioned above.

For example, a metal profile is used, which is formed from aluminum half-shells that are connected to one another by insulating bars. In a preferred embodiment, fire protection liquid is pumped into one or more hollow chambers of connected half-shell profiles of tubular aluminum frame doors. With a given tightness of a profile composite, the fire protection liquid can be filled directly into the hollow chamber. If there is a leak in the profile combination, it can be sealed beforehand. For this purpose, for example, a film tube can be used as a sealant, which is introduced into the respective hollow chamber before the filling process.

For example, a fire protection liquid can be used, which polymerizes into a gel after it has been filled into the cavity. A gel can also be formed first, which is still flowable and is then pumped into the respective hollow chamber.

The introduction of a flowable fire protection material has several advantages.

There is no need to provide separate blanks of solid fire protection materials.

The free-flowing fire protection material - such as the fire protection gel in particular - optimally fills the cavity.

The free-flowing fire protection agent has very good contact with the inner wall areas of the metal profile, so that the metal profile is immediately cooled in the event of a fire.

The filling of inner hollow chambers of metal profiles can replace the conventionally used mineral-based profile fillings such as Promaxon.

Furthermore, fire tests have shown that the required amount of profile filling, which is currently necessary for the reliable provision of a desired fire protection performance, can be significantly reduced by configurations of the invention. Up until now, it has been necessary to fill all three hollow chambers with fire protection materials for a metal profile frame made from two light metal tubular profiles that are connected to one another by insulating bars in order to achieve a fire resistance class of EI90 (the fire protection closing element withstands fire from one side for 90 minutes). When using the teaching of embodiments of the invention, it is sufficient with otherwise unchanged metal profile frames to fill only one of three chambers.

In applications where filling a cavity in a metal profile with a free-flowing mass is not possible or not economically viable, a filling element can also be produced by filling an envelope outside of the metal profile with fire protection gel or a fire protection liquid that forms fire protection gel and then filling it accordingly Case is introduced into the hollow chamber profile.

The shell can also be stiffened with stiffening elements. For example, rods made of cardboard or other suitable materials - for example, wooden sticks - preferably made of a porous material, which through Fire protection liquid can be soaked - are placed in a film tube together with the fire protection liquid.

It is preferably provided to weld rods made of cardboard or the like, which correspond in cross section to the inner cross section of the hollow chamber to be filled, into foil tubes together with the fire protection liquid under vacuum and thereby produce a dimensionally stable insert for profile filling.

With such dimensionally stable inserts, metal profiles open on one side can also be filled with the fire protection gel of interest here.

Further configurations not belonging to the invention provide for using the same fire protection gel, which is used for filling fire protection glass panes of a glazing for fire protection closure elements, also for the production of fire protection mats, which are to be used for filling fire protection closure element bodies.

Thus, embodiments not belonging to the invention provide a fire protection mat for filling a cavity of a fire protection closure element, wherein the fire protection mat comprises a flexible shell and the fire protection gel enclosed in the shell.

It is preferred that the casing has a film tube or plastic film tube.

It is preferred that the firestop gel is vacuum sealed within the envelope.

It is preferred that the shell contains a stiffening element.

It is preferred that one or more stiffening elements selected from a group of stiffening elements including a honeycomb element, a porous body, a cardboard honeycomb element, a flexible rod and a flexible framework are provided in or on the shell.

Thus, with this configuration, which does not belong to the invention, a fire protection closure element can be created, comprising a jacket enclosing a cavity and at least one fire protection mat according to one of the above configurations inserted in the cavity.

It is preferred that the shell is formed from metal sheets or from panels made of a material based on wood-based materials.

It is preferred that the fire protection closing element is designed as a fire protection door leaf, fire protection door leaf or as a fire protection panel to form a fire protection wall.

It is preferred that at least one fire protection mat according to one of the above configurations and a mineral fiber fire protection mat are contained in the cavity or are placed one on top of the other.

1. A) Bereitstellen einer Hülle aus einem flexiblen fluiddichten Material mit wenigstens einer Öffnung;
2. B) Befüllen der Hülle mit einem Brandschutzgel oder einer zu einem Brandschutzgel polymerisierbaren Brandschutzflüssigkeit;
3. C) fluiddichtes Verschließen der Hülle.

A preferred embodiment of the method, which does not belong to the invention, thus comprises a step for producing a fire protection mat, comprising the steps:

1. A) providing an envelope of flexible fluid-tight material having at least one opening;
2. B) filling the envelope with a fire protection gel or a fire protection liquid that can be polymerized to form a fire protection gel;
3. C) sealing the envelope fluid-tight.

It is preferred that step A) includes providing a film tube.

It is preferred that step C) comprises vacuum sealing the envelope.

According to embodiments not belonging to the invention, a fire protection mat is made available, which is formed by a fire protection gel contained in a cover. The fire-resistant gel is the same as the fire-resistant gel in fire-resistant glass panes of glazed fire barriers from a series of fire-resistant barriers with and without glazing.

A particular aspect of the preferred configurations not belonging to the invention relates to the use of a fire protection liquid or a fire protection gel formed from it for the production of fire protection mats for filling fire protection closure elements, in order to produce a series of fire protection closure elements with or without glazing. For example, the fire protection liquid is pumped into pre-assembled foil tubes. The foil tubes filled with the fire protection liquid are then welded under vacuum. This gives a flexible fire protection mat, which is used, for example, as a door insert for sheet steel doors with fire protection applications or as an insert for fire protection doors with fire protection applications. For a more detailed structure of the fire protection closures that can be filled with such fire protection mats, reference is made to the aforementioned company publications, which form part of the present disclosure. The fire protection mats can be used in particular as fire protection mats in the fire protection elements, as in the EP 1 533 462 A2 are described and shown.

Basically, the shape of the fire protection mat can be freely selected. Rectangular, triangular, round, ellipsoidal shapes etc. are conceivable. As a result, extremely flexible fire protection mats can be produced, which are used in one or more as inserts in corresponding fire protection closure elements.

In addition to the pure fire protection liquid filling, honeycomb mats, in particular made of cardboard, can also be added to the filling. As a result, the fire protection mat can have greater rigidity and dimensional stability.

In a preferred embodiment, the liquid-filled fire protection mat is sandwiched with another insulating material, such as rock wool or mineral wool or the like.

In the Figures 1 to 4 are different embodiments of fire protection closure elements 10 shown, each having at least one metal profile frame 12, which is formed from individual metal profiles. Examples of the fire protection closure elements 10 are in figure 1 a fire door 14 with a frame 16 in fire protection training and a fire door leaf 18, in figure 2 and 3 a fixed glazing 20 with a fire door, which has a fire door leaf 18, and in figure 4 in turn, a fire door 14 with a fire door leaf 18 and a frame 16 is shown.

The fire protection closure elements 10 each have the metal profile frame 12 into which a filling 22 in the form of fire protection glass panes 24 is inserted.

As is known from the literature references mentioned above, the fireproof glass panes 24 have at least one first and one second glass pane, which form a hollow space between them, which is filled with fireproof gel 26, in a manner that is not detailed here.

The same fire protection gel 26 is also located in at least one cavity 26 of the respective metal profile frame 12.

To produce the metal profile frames 12 shown, the procedure is such that first the metal profile frames 12 are produced in a conventional manner.

In the embodiments of Figures 1 to 3 For example, the respective metal profiles 28 are formed from a first metal shell 30 and a second metal shell 32, which are connected to one another by at least two insulating bars 34 in each case.

The metal shells 30, 32 are for example made of light metal - extruded in the form of tubular profiles 36 - in particular aluminum or aluminum alloys.

Thus, each metal shell 30, 32 has a hollow chamber within it. As a result, a first hollow chamber 36 is formed in the first metal shell 30 , a second hollow chamber 38 is formed in the second metal shell 32 , and a third hollow chamber 40 is formed between the insulating webs 34 .

Before or during the assembly of the metal profile frame 12 by the metal profiles 28 formed in this way, at least one of the hollow chambers 36 , 38 , 40 is filled with a fire protection liquid which can polymerize to form a fire protection gel 26 . Here the filling of the respective cavity within the metal profile 28 can take place analogously to a known filling of cavities in fire protection glasses.

For example, the metal profile frame 12 can first be completely assembled, leaving a filling opening and/or a ventilation opening through which the fire protection liquid can be filled.

If the respective hollow chamber 36, 38, 40 to be filled is not tight, a sealant can first be introduced.

For example, a film tube is introduced into the respective hollow chamber 36, 38, 40, which can then be filled with the fire protection liquid.

After filling, it can polymerize to form the fire protection gel.

In another procedure, an already pre-polymerized or fully polymerized fire protection gel, which is still sufficiently free-flowing, is filled into the hollow chamber 36, 38, 40 to be filled.

If only one of the hollow chambers 36, 38, 40 is filled, then a central hollow chamber is preferably filled, i.e. in the illustrated exemplary embodiment, for example, the third hollow chamber 40.

The metal profiles 28 can, as in the Figures 1 to 3 shown, be formed from light metal extruded profiles. But it is also possible to use other metal profiles.

For this purpose, in the figure 5 shown as a further embodiment, a tubular steel profile. Such a tubular steel profile can also have a hollow chamber 36 which is filled with a fire protection gel. Here, too, the polymerisation to form a fire protection gel can take place before filling or after filling.

In figure 5 Another possible procedure for producing a metal profile 28 filled with a fire protection gel is indicated.

For this purpose, an insert 42 is placed outside of the metal profile 28, as shown in figure 8 is shown. The insert 42 has an envelope 44, in particular made of a tubular film, a fire protection liquid filled into the envelope 44 or a fire protection gel 26 formed from it, and one or more stiffening elements 46. The stiffening element 46 is made, for example, by a tubular rod Cardboard or formed from another preferably porous material. The external dimensions of the stiffening element 46 are adapted to the internal dimensions of the cavity 36 , 38 , 40 to be filled, so that the respective cavity 36 , 38 , 40 is filled with fire protection gel 26 as far as possible. The stiffening elements 46 and the fireproofing gel 26 or the fireproofing liquid for forming the fireproofing gel 26 are introduced into the shell 44 and vacuum welded. This creates the insert 42 with a predetermined shape contour.

the figures 6 and 7 show metal profiles 28 from the exemplary embodiments of FIG Figures 1 to 4 , where at the figure 6 the first hollow chamber 36 and the third hollow chamber 40 are filled with fire protection gel 26 . In the figure 7 only the third hollow chamber 40 is filled.

Fire tests have shown that metal profiles 28 filled in this way meet the requirements for a fire protection closure element 10 with a resistance class for 90 minutes.

As in figure 1 and figure 2 indicated, the inner walls of hollow chambers 36, 38, 40 can be provided with inwardly projecting ribs 48. These ribs 48 can be produced, for example, when the metal shells 30, 32 are extruded.

These ribs 48 are surrounded by the fire protection gel 26 . They thus ensure a good cooling effect with a corresponding cooling occurring in the event of a fire by the fire protection gel 26.

The fire protection glass panes 24 are also produced as part of the production of the fire protection closure elements 10 , 120 . For more details on the known production of the fire-resistant glass panes 24 is on DE 10 2015 119 042 A1 and the DE 10 2014 114 241 A1 referred. For example, the production takes place of the fire-resistant glass panes at the same or a neighboring production site as the production of the fire-resistant closure element bodies, ie metal profiles, frames, door or gate leaves of the fire-resistant closure element 10, 120.

The same fire protection gel 26 is used to fill the fire protection glass panes 24 and to fill a cavity in a fire protection closure element body, such as the metal profile frame 12 . The filling can be done directly or by inserting an insert, particularly in the case of tight or sealed cavities.

The insert can also be present as a fire protection mat 110, by means of which fire protection closing element bodies in the form of door leaves or gate leaves for fire protection doors and fire protection gates can be filled instead of the previously known fire protection mats. This is explained in more detail below with reference to

Fire protection closure elements 10, 120 can thus be manufactured in a production series with and without glazing and also in different designs, with the same fire protection gel 26 being used to fill the fire protection glass panes 24 and to fill other cavities in fire protection closure elements 10, 120.

the Figures 8 and 9 show a first embodiment of a fire protection mat 110, which has a shell 112 and the fire protection gel 26 enclosed therein.

The same fire protection gel is used as the fire protection gel 26 as is used to fill fire protection glasses in the production of the glazed fire protection closure elements 10 . The sleeve 112 is formed, for example, by a tubular film 116 made of a plastic film.

To produce the fire protection mat 110, a film tube 116 is provided in a desired shape - rectangular, triangular, round, cuboid or wedge-shaped... - and in the desired size, and a fire protection liquid, which the fire protection gel 26 can form through polymerization, or the fire protection gel 26 is filled through an opening in the film tube 116 . The film tube 116 is welded after filling under vacuum, so that in the Figures 8 and 9 illustrated fire protection mat 110 is formed.

This fire protection mat 110 has a consistency similar to gel-filled cold packs or heat packs used for medical cold applications or heat applications. The fire protection mat 110 is, as shown in 9 is shown, flexible and adapts to the inner contours of a cavity of a fire protection closure element 120 optimally. It is therefore not necessary to preform the fire protection mat 110 in accordance with the cavity.

It is also possible to fill a cavity with a plurality of fire protection mats 110, for example to stack many smaller fire protection mats 110 on top of one another in the cavity.

12 and 13 show an example of a fire protection closure element 120 in the form of a fire protection door leaf 122, which is constructed in a box-cover design. Accordingly, a shell sheet 124 and a cover sheet 126 form a shell 128 which encloses a cavity. This cavity 130 is correspondingly filled with at least one fire protection mat 110 or—as shown—a plurality of such fire protection mats 110 . The jacket 128 is then closed by applying the cover plate 126 to the jacket plate 124 .

As 9 shows, the fire protection mat 110 can be designed to be very flexible, which can make handling more difficult when the fire protection mats 110 have larger dimensions. It may therefore be desirable to limit the flexibility of the fire protection mat 110 somewhat, ie it may be desirable for the fire protection mat 110 to be somewhat more dimensionally stable. This can be done by inserting a stiffening element 132, a corresponding embodiment is in 10 shown.

The stiffening element 132 can have different shapes. For example, rods made of plastic or some other flexible material could be used. Preferably, stiffening elements 132 made of porous materials that can be impregnated with fire protection liquid are provided. At the in 10 illustrated embodiment is provided as a stiffening element 132, a honeycomb mat made of a cardboard material.

It will now turn on again 13 Referring to FIG. 1, which shows the fire barrier 120. FIG. The cavity 130 can only be filled with fire protection mats 110 . However, one or more fire protection mats 110 can also be provided together with one or more conventional insulation materials. For example, a mineral wool filling—rock wool or glass wool or the like—can be reinforced by fire protection mats 110 in areas that are particularly at risk of heat.

11 shows a further embodiment of the fire protection mat 110, the fire protection mat 110 itself having a sandwich structure 134 made of fire protection gel 26 and a further insulating material 136.

For this purpose, the fire protection gel 26 is accommodated in a first cover 112 . The first fire protection mat unit thus formed is housed in a second shell 138 together with the additional insulating material 136 . Rock wool or mineral wool can be provided as a further insulating material 136 . The second sleeve 138 is preferably also sealed in a fluid-tight manner. The second shell 138 can also contain the fire protection gel 26 in addition to the additional insulating material 136; In another embodiment, fire protection gel 26 is only housed in first shell 112 and first shell 112 and the additional insulating material 136 are housed in second shell 138—but without fire protection gel.

The shell 112, 138 is preferably formed from a thermoplastic material which softens and melts when exposed to heat.

In the event of a fire, the fire protection gel 26 has a cooling effect. In particular, when the shell 112, 138 melts, for example in the case of a fire protection gel that is provided in the form of a hydrogel with dissolved salts, water is split off, which has a cooling effect due to the evaporation cold.
