Description

Die Erfindung betrifft eine aus mehreren parallel zueinander verlaufenden Teilprofilen gebildete Zarge für Feuerschutztüren.The invention relates to a frame formed of several mutually parallel partial profiles frame for fire doors.

Bei Feuerschutztüren ist es nicht nur erforderlich den Wärmeübergang durch das Türblatt zu begrenzen, sondem auch den Wärmeübergang durch die Türzarge am geschlossenen Türblatt vorbei. Aus diesem Grund gibt es viele Vorschläge dazu, Zargenprofile nicht als einteiliges Metallprofil auszuführen, sondem aus mehreren, parallel zueinander verlaufenden Metallprofilen, welche voneinander mehr oder minder gut thermisch getrennt sind. Im folgenden sei eine kleine Auswahl von Beispielen dazu erwähnt:For fire doors, it is not only necessary to limit the heat transfer through the door leaf, but also the heat transfer through the door frame on the closed door leaf over. For this reason, there are many proposals to perform frame profiles not as a one-piece metal profile, but from several parallel metal profiles, which are more or less thermally separated from each other. Below is a small selection of examples:

In der DE 2521736 B1 wird vorgeschlagen, eine Zarge aus zwei parallel verlaufenden Stahlblechprofilen zu bilden, wobei sich Teile der Profilflächen mit einem kleinen Abstand zueinander überlappen. Im Überlappungsbereich erstrecken sich lokale Erhebungen von einer der beiden Profilfläche auf die andere hin und sind dort mit der anderen Fläche durch Punktschweißen verbunden. Der Überlappungsbereich liegt so, dass er durch eine an der Zarge befestigte Dichtleiste, welche bei geschlossener Tür auch am Türblatt anliegt, abgedeckt werden kann. Diese Bauweise ist bei nicht all zu hohen Feuerschutzanforderungen durchaus vorteilhaft; bei hohen Schutzanforderungen reicht die Dämmwirkung im allgemeinen nicht aus.In the DE 2521736 B1 It is proposed to form a frame of two parallel steel sheet profiles, wherein parts of the profile surfaces overlap with a small distance to each other. In the overlapping area, local elevations extend from one of the two profiled surfaces to the other, where they are connected to the other surface by spot welding. The overlapping area is such that it can be covered by a sealing strip fastened to the frame, which also rests against the door leaf when the door is closed. This construction is quite advantageous for not too high fire protection requirements; With high protection requirements, the insulation effect is generally insufficient.

Die CH 661 092 A5 schlägt für eine Zarge ein Verbundprofil vor. Es wird aus zwei Blechprofilen mit etwa U-förmiger Querschnittsfläche gebildet, welche mit ihren offenen Seiten ineinander geschachtelt sind, ohne sich zu berühren. Die Verbindung der beiden Blechprofile zueinander wird durch einen festen Wärmedämmstoff gebildet, welcher den gemeinsam durch die Blechprofile insgesamt umfassten Raum ausfüllt. Mit Hilfe dieser Bauweise können hohe Feuerschutzanforderungen erfüllt werden. Nachteilig sind die in jedem Fall hohen Kosten wegen des hohen Anteils an festem Wärmedämmstoffes und wegen der nicht ganz einfachen Fertigung.The CH 661 092 A5 proposes a composite profile for a frame. It is formed from two sheet metal profiles with approximately U-shaped cross-sectional area, which are nested with their open sides into each other without touching each other. The connection of the two sheet metal profiles to each other is formed by a solid thermal insulation material, which fills the space that is jointly covered by the sheet metal profiles in total. With this construction high fire protection requirements can be met. The disadvantage in any case high costs because of the high proportion of solid thermal insulation material and because of the not very simple production.

Die DE 3713723 C1 zeigt ein wärmedämmendes Verbundprofil, welches aus zwei Aluminiumstrangpressprofilen und mindestens einem diese verbindenden extrudierten Kunststoffprofil gebildet wird. Lokal ist die Verbindung durch hitzebeständige Metallteile verstärkt. Diese Bauweise kann optisch sehr schön ausgeführt werden. Bedingt durch die Herstellungsweise der einzelnen Teilprofile mit teuren und langwierig herzustellenden Extrusionswerkzeugen und an teuren Strangpressen bzw. Extrusionsanlagen besteht aber eine erhebliche Beschränkung bei der Anpassung der Profilformen an kundenspezifische Anforderungen.The DE 3713723 C1 shows a heat-insulating composite profile, which is formed from two extruded aluminum profiles and at least one extruded plastic profile connecting them. Locally, the connection is reinforced by heat-resistant metal parts. This design can be optically very nicely executed. Due to the method of production of the individual sub-profiles with expensive and tedious to produce extrusion tools and expensive extruders or extrusion systems but a significant limitation in the adaptation of the profile shapes to customer requirements.

Die DE 295 09 383 U1 zeigt ein Verbundprofil, welches aus zwei Stahl-Rohrprofilen und einem dazwischen liegenden Profil aus einem wärmedämmenden Material gebildet wird. Die Verbindung zwischen den einzelnen Teilprofilen erfolgt durch Bolzen, welche an beiden Enden mit einem Widerhaken versehen sind. Diese Bolzen erstrecken sich durch das wärmedämmende Material hindurch und sind mit ihren Enden an den einander zugewandten Seitenwänden der Rohrprofile verhakt. Auch an dieser Bauweise ist nachteilig, dass rasche kundenspezifische Anpassungen kaum möglich sind.The DE 295 09 383 U1 shows a composite profile, which is formed of two steel tube profiles and an intermediate profile made of a thermally insulating material. The connection between the individual sub-profiles is made by bolts, which are provided at both ends with a barb. These bolts extend through the heat-insulating material and are hooked with their ends on the mutually facing side walls of the pipe profiles. Another disadvantage of this design is that rapid customer-specific adaptations are hardly possible.

Das Dokument FR 2781517 zeigt eine Zarge mit den Merkmalen des Oberbegriffs des Anspruchs 1.The document FR 2781517 shows a frame with the features of the preamble of claim 1.

Die der Erfindung zu Grunde liegende Aufgabe besteht demgegenüber darin, eine Bauweise für Zargen von Feuerschutztüren vorzuschlagen, mit Hilfe derer sehr rasch und flexibel kundenspezifische Ausführungsformen verwirklicht werden können. Entsprechend der vorzuschlagenden Bauweise sollen auch Zargen für sehr hohe Feuerschutzanforderungen verwirklichbar sein und die Bauweise soll vergleichsweise kostengünstig herstellbar sein.The object of the invention is based on the other hand, to propose a construction for frames of fire doors, with the help of which can be realized very quickly and flexibly customized embodiments. According to the proposed construction also frames for very high fire protection requirements should be feasible and the construction should be relatively inexpensive to produce.

Zum Lösen der Aufgabe wird vorgeschlagen die Zarge aus zwei parallel zueinander angeordneten Stahlblechprofilen und einem dazwischen, ebenfalls parallel dazu angeordneten, festen Dämmstoffstreifen zu bilden. Die beiden Stahlblechprofile bilden zusammen etwa ein C- oder U-Profil, welches mit der offenen Profilseite zu jener Mauer hin angeordnet wird, an der die Zarge befestigt wird. Die Querschnittsfläche des C- oder U-Profils wird durch die Querschnittsfläche des Dämmstoffstreifens geteilt, indem sich diese von der Basis des durch die beiden Stahlblechprofile gebildeten C- oder U-Profils aus bis auf die Höhe der Enden der Schenkel dieses Profils erstreckt, ohne an den Schenkeln anzuliegen.To solve the problem it is proposed to form the frame of two mutually parallel steel sheet profiles and an intermediate, also arranged in parallel, solid insulation strips. The two sheet steel profiles together form approximately a C or U-profile, which is arranged with the open profile side to the wall, to which the frame is attached. The cross-sectional area of the C or U-profile is divided by the cross-sectional area of the insulating strip, extending from the base of the formed by the two steel sheet profiles C or U-profile from to the level of the ends of the legs of this profile, without to rest on the thighs.

Die Erfindung sowie vorteilhafte Ausführungsmerkmale werden an Hand von Zeichnungen veranschaulicht und erklärt:

The invention as well as advantageous embodiment features are illustrated and explained with reference to drawings:
Fig. 1:
shows a first embodiment of a frame according to the invention in profile view.
Fig. 2:
shows a second embodiment of a frame according to the invention in profile view.

Etwa in der Mitte der Basis des durch die beiden Stahlblechprofile 1, 2 gebildeten C- oder U-Profils ist bei beiden einzelnen Stahlblechprofilen jeweils eine Profilwand 1.2, 2.2 ausgebildet, welche etwa parallel zur Ebene des Türblattes 20 liegt. Diese beiden Profilwände 1.2, 2.2 liegen an gegenüberliegenden Flächenbereichen des festen Dämmstoffstreifens 3 an und sind durch diesen hindurch mittels punktuell angreifender metallischer Verbindungselemente 4, typischerweise Schrauben oder Blindniete miteinander verbunden.Approximately in the middle of the base of the formed by the two sheet steel profiles 1, 2 C or U-profile in each case a single profiled wall 1.2, 2.2 is formed in each individual sheet steel profiles, which is approximately parallel to the door panel 20 level. These two profile walls 1.2, 2.2 abut against opposite surface areas of the solid insulating strip 3 and are connected to each other by means of selectively attacking metallic fasteners 4, typically screws or blind rivets.

Für die Feuerschutzfunktion ist es wichtig, dass der Übergangsbereich zwischen den beiden Stahlblechprofilen 1, 2 an der Oberfläche der Zarge bei geschlossenem Türblatt 20 von diesem abgedeckt wird. Dann grenzt das erste der beiden Stahlblechprofile nur an den ersten der beiden durch die Feuerschutztür getrennten Räume und das zweite der beiden Stahlblechprofile nur an den zweiten Raum. Somit wird vermieden, dass Wärme direkt in nur einem Stahlblechprofil von einem Raum in den anderen Raum fließen kann.For the fire protection function, it is important that the transition region between the two steel sheet profiles 1, 2 is covered on the surface of the frame with the door closed 20 of this. Then, the first of the two sheet steel profiles adjoins only the first of the two spaces separated by the fire door and the second of the two sheet steel profiles only to the second room. This avoids that heat can flow directly from one room to another in just one sheet steel profile.

Der feste Dämmstoffstreifen 3 besteht aus hitzefestem, schlecht wärmeleitendem Material, beispielsweise auf Basis Gipskarton. Er ist so bemessen, dass er den durch die beiden Stahlblechprofile gemeinsam gebildeten Hohlraum in zwei Hohlräume 1.1, 2.1 teilt. Damit wird auch Wärmeübergang zwischen den beiden Stahlblechprofilen 1, 2 durch Wärmestrahlung unterbunden. Der Dämmstoffstreifen 3 kann ganz einfach eine rechteckförmige Querschnittsfläche aufweisen. Er braucht also nicht als Profil gefertigt zu sein, sondem er kann aus Platten oder Blöcken herausgeschnitten werden. Damit wird bezüglich der gewünschten, für den jeweiligen Einsatzfall optimalen Abmessungen und Materialvarianten große Flexibilität ermöglicht.The solid insulation strip 3 is made of heat-resistant, poor heat-conducting material, for example based on plasterboard. It is dimensioned so that it divides the hollow space formed by the two steel sheet profiles into two cavities 1.1, 2.1. This heat transfer between the two steel sheet profiles 1, 2 is prevented by heat radiation. The insulation strip 3 can easily have a rectangular cross-sectional area. So it does not need to be made as a profile, but it can be cut out of plates or blocks. In this way, great flexibility is made possible with regard to the desired dimensions and material variants which are optimal for the respective application.

Das durch die beiden Stahlblechprofile 1,2 gemeinsam gebildete etwa U- oder C-förmige Profil ist zu jener Mauer hin offen, an der die Zarge befestigt ist. Auch der Dämmstoffstreifen 3 liegt nicht direkt an dieser Mauer an. Trotz dem damit ermöglichten Wärmeübergang über die Mauer sind normgemäße Feuerschutzeigenschaften durchaus erreichbar, da alle üblichen Baustoffe für Mauern ausreichend hitzefest und wärmedämmend sind. Der Hauptvorteil dieser offenen Bauweise liegt darin, dass damit die beiden Stahlblechprofile 1, 2 eine sehr einfache Profilform aufweisen können. Damit können sie einfach durch Abkanten eines Blechstreifens in einer herkömmlichen Abkanntpresse, wie sie in annähernd jedem Metallverarbeitungsbetrieb vorhandenen ist, gebildet werden. Damit wird größtmögliche Anpassungsfähigkeit an spezielle Kundenwünsche erreicht.The approximately U-shaped or C-shaped profile formed jointly by the two sheet steel profiles 1, 2 is open towards the wall to which the frame is fastened. Also, the insulation strips 3 is not directly on this wall. Despite the heat transfer through the wall, standard fireproofing properties are easily achievable, since all the usual building materials for walls are sufficiently heat-resistant and heat-insulating. The main advantage of this open design is that it allows the two sheet steel profiles 1, 2 have a very simple profile shape. So you can easily by folding a metal strip in a conventional Abkennpresse, as it is available in almost every metal processing plant, be formed. This achieves the greatest possible adaptability to special customer requirements.

In Anpassung an sehr hohe Feuerschutzanforderungen kann der zwischen jeweils einem Stahlblechprofil 1, 2 und dem Dämmstoffstreifen 3 gebildete Hohlraum 1.1 bzw. 2.1 durch ein weiteres wärmedämmendes Material wie beispielsweise Mineralwolle ausgekleidet werden.In adaptation to very high fire protection requirements of the formed between each a sheet steel profile 1, 2 and the insulating strip 3 cavity 1.1 or 2.1 can be lined by another heat-insulating material such as mineral wool.

Aus optischen Gründen und um den Dämmstoffstreifen 3 gegen mechanischen Beschädigung zu schützen, sollte er auch auf der Seite des Türblattes durch eine Teilfläche eines Stahlblechprofils abgedeckt werden. Bei den gezeigten Beispielen ist in Profilansicht ein von einem Raum zum anderen Raum hin ausgerichteter Profilwandbereich um 180° zur Innenseite des Blechprofils hin umgebogen, sodass eine Schleife 1.3 gebildet wird. Der zurück verlaufende Profilwandbereich dieser Schleife ist nochmals um 90° zu einer normal auf die Mauer hin verlaufende Profilwand 1.2 gebogen. Der Abstand zwischen den beiden Biegungen und damit die Breite der Lasche 1.3 ist bei der Ausführung gemäß Fig. 1 gleich der Stärke des Dämmstreifens 3.For visual reasons and to protect the insulation strip 3 against mechanical damage, it should also be covered on the side of the door leaf by a partial surface of a sheet steel profile. In the examples shown, in profile view, a profile wall region oriented from one space to the other space is bent by 180 ° to the inside of the sheet metal profile, so that a loop 1.3 is formed. The receding profile wall portion of this loop is bent again by 90 ° to a normal to the wall extending profile wall 1.2. The distance between the two bends and thus the width of the tab 1.3 is in accordance with the execution Fig. 1 equal to the thickness of the Dämmstreifens 3.

Bei der Ausführung gemäß Fig. 2 ist die Breite der Lasche 1.3 größer als die Breite des Dämmstoffstreifens 3 einschließlich der daran anliegenden Profilwand 2.2. Dadurch steht die Schleife 1.3 bei der Ausführung gemäß Fig. 2 über den Dämmstreifen 3 und die daran anliegende Profilwand 2.2 über. Im überstehenden Bereich kann gut ein Brandschutzstreifen 10, also ein Streifen aus einem bei Hitze aufquellenden und damit abdichtenden Material, angeordnet werden.In the execution according to Fig. 2 the width of the tab 1.3 is greater than the width of the insulating strip 3 including the adjacent profile wall 2.2. As a result, the loop 1.3 is in accordance with the execution Fig. 2 on the Dämmstreifen 3 and the adjoining profile wall 2.2 on. In the projecting area, a fire protection strip 10, ie a strip of heat-swelling and thus sealing material, can be arranged well.

Aus mehreren Gründen ist es vorteilhaft die zweite Profilwand 2.2 jener beiden Profilwände der Stahlblechprofile zwischen denen der Dämmstoffstreifen 3 eingeklemmt ist, von dem sie haltenden Teil des Stahlblechprofils 2 aus in Richtung von der Mauer weg abstehen zu lassen. Weiters ist es vorteilhaft, wenn sie das von der Mauer entfernt liegende Ende der Profilfläche des Stahlblechprofils 2 bildet. Damit werden geometrisch einfache Profilformen möglich und die durch die Befestigungsteile 4 unterbrochene außen liegende Oberfläche der Profilwand 2.2 ist für den Zusammenbau gut für ein Werkzeug zugänglich und bei geschlossenem Türblatt durch dieses abgedeckt.For several reasons, it is advantageous to have the second profile wall 2.2 of those two profile walls of the steel sheet profiles between which the insulation strips 3 is clamped, from which they keep holding part of the sheet steel profile 2 in the direction away from the wall. Furthermore, it is advantageous if it forms the remote from the wall end of the profile surface of the sheet steel profile 2. This geometrically simple profile shapes are possible and interrupted by the fasteners 4 outer surface of the profile wall 2.2 is well accessible for assembly for a tool and covered with the door closed by this.

Die freien (von der Basis entfernt liegenden) Enden der Schenkel des durch die beiden Stahlblechprofile gebildeten C- oder U-Profils sind an einzelnen Stellen durch daran befestigte Blechlaschen 5 überbrückt. Diese Blechlaschen erstrecken sich also nicht über die ganze Länge der Stahlblechprofile, sondem nur an mehreren Stellen über eine Länge im Bereich von typischerweise etwa zwei Zentimetern. Die Befestigung der Zarge an der Mauer erfolgt durch eine Schraubverbindung 6, welche an einer Bohrung in den einzelnen Blechlaschen 5 angreift. Damit die Schraubverbindung hergestellt werden kann ist das Stahlblechprofil 2 in den Längsbereichen der Blechlaschen 5 mit einem Durchbruch versehen. Diese Durchbrüche sind sinnvoller Weise in einem solchen Profilbereich des Stahlblechprofils angeordnet, welcher bei geschlossenem Türblatt durch dieses abgedeckt wird. Der Durchbruch kann durch eine Abdeckkappe 9 verschlossen werden.The free (remote from the base) ends of the legs of the formed by the two steel sheet profiles C or U-profile are bridged at individual points by sheet metal tabs 5 attached thereto. These metal tabs do not extend over the entire length of the sheet steel profiles, but only in several places over a length in the range of typically about two centimeters. The attachment of the frame to the wall is carried by a screw 6 which engages a hole in the individual metal tabs 5. So that the screw connection can be made, the steel sheet profile 2 is provided in the longitudinal regions of the metal tabs 5 with an opening. These breakthroughs are sensibly arranged in such a profile range of the sheet steel profile, which is covered by the door leaf closed by this. The breakthrough can be closed by a cap 9.

Zwecks Einstellbarkeit der Lage der Zarge an der Mauer ist zwischen Blechlasche 5 und Mauer eine in ihrer Dicke einstellbare Zwischenlage 7 aus zwei gegeneinander verschiebbaren, durchbohrten oder geschlitzten Keilen eingelegt. Der neben diesen Zwischenlagen verbleibende Spalt zwischen Zarge und Mauer ist an den Rändern durch einen Dichtstreifen 8 aus einer Masse wie typischerweise Brandschutzsillkon verschlossen.For the purpose of adjustability of the position of the frame on the wall is inserted between sheet metal tab 5 and wall in its thickness adjustable intermediate layer 7 of two mutually displaceable, pierced or slotted wedges. The remaining gap between the frame and the wall adjacent to these intermediate layers is sealed at the edges by a sealing strip 8 made of a mass such as typically fire protection compound.
