Description

The invention relates to a method for producing fire protection closure elements. Fire protection closure elements are for example a door, a door leaf, a frame or a fixed glazing in fire protection training. Furthermore, the invention relates to a fire protection finishing element which can be produced thereby and to a fire protection finishing element series that can be produced thereby, that is to say a production series of fire protection closing elements.

Fire and smoke protection tube frame elements are known, for example, from the company brochure "Fire and smoke protection tube frame elements" of the Hörmann KG sales company with the imprint "Stand 04.2017 / Druck 04.2017 / HF84563DE." They have a frame formed from metal profiles which enclose a cavity Frame may be filled by filling elements such as fire glass panes.

As materials for the metals are in particular light metals, such as aluminum or aluminum alloys or steel into consideration. The metal profiles are usually formed of several half-shells, which are interconnected by isolation bars, so as to avoid heat transfer.

To form such tubular frame elements for suitability in fire protection statements, fire protection materials are introduced into cavities of the metal profiles. For this purpose, for example, panels of fire protection materials, such as calcium silicate plates or gypsum boards, cut into rods, in which case the rods are inserted into the metal profiles.

Such methods for producing metal profile frames are in the 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.

To avoid assembly costs, at least for fire protection with lower fire protection class is in the DE 10 2005 014 544 A1 has also been proposed to provide one of the cavities of the respective metal profile with a strip of intumescent material, which is activated only in case of fire.

In particular, the invention also relates to the production of fire protection end elements, as they are known from the company brochure "Functional doors for your home" of the Hörmann KG sales company with the notice 03.2017 / Druck 03.2017 / HF 85115 DE / PDF. Another example of fire protection closures, as they can represent an embodiment of the invention are fire doors, as described in the company publication "Steel and stainless steel sliding gates FST" Hörmann KG sales company with the notice 08/2016 / Druck 08.2016 / HF 86038 DE / PDF are known.

Such fire protection closure elements in the form of wings or frame elements of fire doors or fire doors, especially in box-lid design, have a jacket which encloses a cavity in which a fire protection mat is inserted.

Conventional fire-resistant mats for these purposes are made of mineral fibers. For example, there are fiberglass mats or rock wool mats on the market. The state of the art is on the EP 1 533 462 A2 as well as the cited prior art and the WO 2002/8557 A1 directed.

Fire protection mats based on mineral fibers are complex to produce and difficult to handle. In particular, a blank of such fire protection mats is difficult. Therefore, such fire protection mats must often be kept in stock for respective different sizes of fire protection elements in different sizes.

From the DE 201 14 949 U1 For example, there is known a fire-resistant profile member for making windows, doors, wall panels, facades, and the like having two substantially U-shaped extruded aluminum profile members joined by insulating ribs, with a cavity therebetween filled with a fire barrier insulating material. The fire-resistant insulating compound is formed from magnesium oxychloride cement. The Branschutzisoliermasse may also contain water glass or silica in gel form.

From the DE 10 2015 108 567 A1 is a fire door or a fire door in box-lid construction with a fire retardant filling known. The fire protection device has a reservoir of a nonflammable liquid arranged in the upper region of the fire protection device, which is bound as a gel.

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

From the US 4 223 175 A is the use of liquid in the form of water-filled film tubes for fire protection of cable lines known.

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

The DE 20 2009 015 497 U1 relates to the filling of a cavity of a box-lid sheet fire protection door leaf using metal foils.

In the manufacture of glazed doors and fixed glazings, it is currently envisaged that manufacturers of fixed glazing doors and frames will make the frames and purchase fire-resistant gel-filled fire-resistant glasses from a fire glass manufacturer. In order to make the frames or other door panels fire resistant, additional fire protection materials are procured, which must be prefabricated according to the size of the cavity to be filled. This requires complicated supply chains and a correspondingly complicated storage 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 simplified series production of fire protection end elements of different types should be proposed.

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

A basic idea of the invention is to proceed in the production of the fire protection closure elements in such a way that the fire protection glass panes are filled and that at least a 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.

Preferably, the fire-resistant glass panes are no longer procured and stored as prefabricated and already assembled unit, but produced in the context of the production of fire protection end elements of glass panes, spacer frame and fire protection liquid for forming the filling of fire protection gel.

This requires fewer and less expensive deliveries and a smaller number of different materials. The filling of cavities of bodies of fire protection closure elements, such as e.g. Metal profiles, cavities in door leaves, in particular between box panel and cover sheet, or in fire doors with fire protection gel has even more advantages, which will be explained further hereinafter.

In the context of providing the Feuerschutzabschlusselementkörpers a method for producing metal profile frame for fire protection closure elements is preferably carried out, which is less expensive than the previous production of metal profile frame for fire protection closure elements. Advantageously, a higher fire protection class should be achievable with little effort.

Suitable fire protection gels are given, for example, in the following references, each of which is expressly referred to for further details with regard to the possible composition and the possible preparation of the fire protection gel or the fire protection fluid:

• DE 102 37 395 B4
• DE 197 31 416 C1

• WO 03/061963 A1
• WO 2014/190444 A1 ,

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

For example, a metal profile is used, which is formed of aluminum half-shells, which are interconnected by insulating webs. In a preferred embodiment, fire protection fluid is pumped into one or more hollow chambers of connected half-shell profiles of aluminum tubular frame doors. For a given tightness of a profile composite The fire protection fluid can be filled directly into the hollow chamber. If there is any leaking of the profile composite, 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-retardant liquid can be used which polymerizes into a gel after being filled into the cavity. Also, first, a gel can be formed, which is still flowable and then pumped into the respective hollow chamber.

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

No separate blanks of solid fire protection materials need to be provided.

The flowable fire protection material - in particular the fire protection gel - optimally fills the cavity.

The flowable fire retardant has very good contact with the inner wall areas of the metal profile, so that an immediate cooling of the metal profile occurs in case of fire.

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

Further, fire tests have shown that by embodiments of the invention, the required amount of profile filling, which is currently necessary for the safe position of a desired fire protection performance, can be significantly reduced. So far, it is in a metal profile frame, which is formed of two light metal tubular profiles, which are interconnected by insulating bars, to achieve a fire resistance class EI90 (the Fire protection element withstands one-sided exposure to fire for 90 minutes) it is necessary to fill all three hollow chambers with fire protection materials. Using the teachings of embodiments of the invention, it is sufficient for otherwise unchanged metal profile frame to fill only one of three chambers.

In applications where filling a cavity of a metal profile with a flowable mass is not possible or economically meaningful, manufacture of a filling element can also take place in that a shell with fire protection gel or a fire protection gel-forming fire protection liquid is filled outside the metal profile and then filled accordingly Case is introduced into the hollow chamber profile.

The shell may also be stiffened with stiffening elements. For example, rods made of cardboard or other suitable materials - for example, wood rods - preferably from a porous material which can be impregnated with fire protection liquid - could be introduced in a film tube together with the fire protection liquid.

Preferably, it is provided to weld rods of cardboard or the like, which correspond in cross section to the inner cross section of the hollow chamber to be filled in film tubes together with the fire protection liquid under vacuum and thereby produce a dimensionally stable Einschiebling for profile filling.

With such dimensionally stable Einschieblingen one-sided open metal profiles can be filled with the fire protection gel of interest here.

Further embodiments of the invention provide for the same fire protection gel, which is used for filling of fire-resistant glass panes of a glazing for fire protection closure elements, to be used for the production of fire-resistant mats, which are to be used for filling Feuerschutzschlußelementkörpern.

Thus, embodiments of the invention provide a fire mat for filling a cavity of a fire protection closure element, wherein the fire mat comprises a flexible cover and the fire protection gel enclosed in the cover.

It is preferred that the sheath be a film tube or

Plastic film tube has.

It is preferred that the fire protection gel is vacuum sealed in the casing.

It is preferred that the shell contains a stiffening element.

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

Thus, with this embodiment of the invention, a fire protection closure element can be provided, comprising a shell enclosing a cavity and at least one fire protection mat inserted in the cavity according to one of the preceding embodiments.

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

It is preferred that the fire protection closure element is designed as a fire door leaf, fire protection door leaf or as a fire protection panel for forming a fire protection wall.

It is preferred that at least one fire protection mat according to one of the preceding embodiments and a mineral fiber fire protection mat are contained in the cavity or are superimposed.

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 of the invention thus comprises a step for producing a fire-protection mat, comprising the steps:

1. A) providing a sheath of a flexible fluid-tight material with at least one opening;
2. B) filling the envelope with a fire protection gel or fire-resistant liquid polymerizable to a fire protection gel;
3. C) fluid-tight closure of the shell.

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

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

According to embodiments of the invention, a fire protection mat is provided which is formed by a fire protection gel contained in a shell. The fire protection gel is the same as the fire protection gel in fire-resistant glass panes of glazed fire protection elements from a series of fire protection elements with and without glazing.

A particular aspect of preferred embodiments of the invention relates to the use of a fire-retardant fluid or fire protection gel formed therefrom for the manufacture of fire-retardant mats for filling fire-retardant elements so as to produce a series of fire-retardant closure elements with or without glazing.

For example, the fire protection fluid is pumped into prefabricated film hoses. The foil tubes filled with the fire protection fluid are then welded under vacuum. This results in a flexible fire protection mat, which is used eg as door fitting in steel sheet doors with fire protection application or as an insert in fire doors with fire protection application. For a more detailed construction of the fire barriers, which may be filled with such fire protection mats, reference is made to the aforementioned company publications that form part of the disclosure herein. The fire protection mats can in particular as Fire protection mats are used in the fire protection elements, as in the EP 1 533 462 A2 described and shown.

Basically, the shape of the fire mat can be chosen freely. There are rectangular, triangular, round, ellipsoidal shapes, etc. conceivable. As a result, extremely flexible fire protection mats can be produced, which come to one or more as deposits in corresponding fire protection elements for use.

In addition to the pure fire protection liquid filling and honeycomb mats, especially from cardboard, can be supplemented for filling. As a result, the fire protection mat can obtain a higher rigidity or dimensional stability.

In a preferred embodiment, a sandwich construction of the liquid-filled fire-resistant mat is provided with another insulating material, such as e.g. Rock wool or mineral wool or the like, provided.

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

Before or in the course of the composition of the metal profile frame 12 by the metal profiles 28 thus formed, 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 be carried out analogously to a known filling of cavities in fire-resistant glass.

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

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

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

After filling, a polymerization out to the fire protection gel can take place.

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

If only one of the hollow chambers 36, 38, 40 is filled, then preferably a filling of a middle hollow chamber takes place, that is to say in the exemplary embodiment illustrated, for example, the third hollow chamber 40.

The metal profiles 28 can, as in the FIGS. 1 to 3 represented, be formed from light metal extrusions. But it is also the use of other metal profiles possible.

This is in the FIG. 5 represented as a further embodiment, a tubular steel profile. Also, such a tubular steel profile may have a hollow chamber 36 which is filled with a fire protection gel. Again, the polymerization to a fire protection gel can be done before filling or after filling.

In FIG. 5 is yet another possible procedure for producing a filled with a fire protection gel metal profile 28 indicated.

For this purpose, a Einschiebling 42 is provided outside of the metal section 28, as in FIG. 8 is shown. The insert 42 has a casing 44, in particular made of a film tube, a fire protection liquid filled in the casing 44 or a fire protection gel 26 formed therefrom and one or more stiffening elements 46. The stiffening element 46 is formed for example by a pipe rod made of cardboard or other preferably porous material. The stiffening element 46 is adapted from its outer dimensions to the inner dimensions of the cavity 36, 38, 40 to be filled, so that the respective hollow chamber 36, 38, 40 is filled with fire protection gel 26 as far as possible. The stiffening elements 46 and the fire protection gel 26 or the fire protection liquid for forming the fire protection gel 26 are introduced into the shell 44 and vacuum-welded. This results in Einschiebling 42 with predetermined shape contour.

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

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

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

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

The production of fire protection glass panes 24 also takes place within the framework of the production of fire protection closure elements 10, 120. For this purpose, the glass panes are connected to each other by means of spacers, and the thus formed fire protection cavity between the glass panes is filled with fire protection gel 26. For further details of the known per se manufacture of the fire glass panes 24 is on the DE 10 2015 119 042 A1 and the DE 10 2014 114 241 A1 directed. For example, the production of the fire-resistant glass panes takes place at the same or an adjacent production facility as the production of the fire protection element bodies, ie metal profiles, frames, door or gate wings of the fire protection closure element 10, 120.

It is the same fire protection gel 26 for filling the fire glass panes 24 and for filling a cavity of a fire protection element body, such. of the metal profile frame 12 is used. The filling can be done directly in particular with dense or sealed cavities or by inserting a Einschieblings.

The Einschiebling can also be present as a fire mat 110, by means of which fire protection element closure body in the form of door leaves or door leaves for fire doors and fire doors can be filled instead of the previously known fire protection mats. This will be explained in more detail below.

Thus, fire protection closure elements 10, 120 can be produced in a production series with glazing and without glazing and also in a different construction, wherein the same fire protection gel 26 for filling the Fire protection glass panes 24 and for filling other cavities in fire protection end elements 10, 120 is used.

The 8 and 9 show a first embodiment of a fire mat 110 having a shell 112 and the fire protection gel 26 enclosed therein.

As fire protection gel 26, the same fire protection gel is used, as it is used for filling fire protection glass in the production of glazed fire protection end elements 10. The shell 112 is formed, for example, by a film tube 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 can form the fire protection gel 26 by polymerization, or the same Fire protection gel 26 are filled through an opening in the film tube 116. The film tube 116 is welded after filling under vacuum, so that in the 8 and 9 shown fire protection mat 110 is formed.

This fire mat 110 has a similar consistency to gel-filled refrigerated packs or heat packs used in medical refrigeration applications or heat applications. The fire mat 110 is, as in Fig. 9 is shown, flexible and adapts to the inner contours of a cavity of a fire protection end element 120 optimally. It is thus not necessary to preform the fire mat 110 according to 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 each other and one above the other in the cavity.

Fig. 12 and 13 show an example of a fire protection closure element 120 in the form of a fire door panel 122 constructed in box-lid construction is. Accordingly, a jacket plate 124 and a cover plate 126 form a jacket 128 which encloses a cavity. This cavity 130 is filled with at least one fire protection mat 110 or - as shown - several such fire protection mats 110. Subsequently, the jacket 128 is closed by applying the cover plate 126 to the jacket plate 124.

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

The stiffening element 132 may have different shapes. For example, rods could be used, for example made of plastic or other flexible material. Preferably, stiffening members 132 are provided of porous materials that can be infiltrated by fire-resistant liquid. At the in Fig. 10 illustrated embodiment, a honeycomb mat is provided as a stiffening element 132 of a cardboard material.

It will be up again Fig. 13 Referring to the fire protection element 120 shows. The cavity 130 may be filled exclusively with fire protection mats 110 in accordance with the invention training. However, one or more fire-resistant mats 110 may also be provided together with one or more conventional insulation materials.

For example, a filling made of mineral wool - rock wool or glass wool or the like - be reinforced at particularly heat-prone areas by fire-resistant mats 110 in accordance with the invention training.

Fig. 11 shows a further embodiment of the fire protection mat 110, wherein the fire protection mat 110 itself has a sandwich structure 134 of fire protection gel 26 and another insulation material 136.

For this purpose, the fire protection gel 26 is housed in a first shell 112. The first fire protection mat unit formed thereby is accommodated in a second casing 138 together with the further insulation material 136. As a further insulating material 136 rock wool or mineral wool may be provided.

Preferably, the second shell 138 is closed fluid-tight. The second sheath 138 can also contain the fire protection gel 26 in addition to the further insulation material 136; In another embodiment, only in the first shell 112 fire protection gel 26 and in the second shell 138, the first shell 112 and the further insulation material 136 - but without fire protection gel - housed.

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

In case of fire, the fire protection gel 26 acts cooling. In particular, during melting of the shell 112, 138, for example, in a fire protection gel, which is provided in the form of a hydrogel with dissolved salts, split off water, which acts cooling by the evaporative cooling.
