Description

Die Erfindung betrifft eine zweiflügelige Glastür mit Mittelanschlag für Brandschutzzwecke mit jeweils einer einen im Brandfall aufschäumenden Schutzwirkstoff enthaltenden Brandschutzscheibe, sowie mit die Ränder der Brandschutzscheibe umgreifenden, aus Metallprofilen bestehenden Rahmenteilen, wobei sich die im Bereich des Mittelanschlags angeordneten Rahmenteile Zusammensetzen aus Schenkein, die sich parallel zu den Flächen der Brandschutzscheibe erstrecken, aus einem der schmalen Stirnfläche der Brandschutzscheibe gegenüberliegenden Steg zwischen den beiden Schenkein, und ferner aus einer im wesentlichen rechtwinklig zu dem Steg angeordneten Anschlagleiste.The invention relates to a double-leaf glass door with a central stop for fire protection purposes each with a protective agent that foams up in the event of a fire containing fire screen, as well as with the edges of the fire screen encompassing frame parts consisting of metal profiles, the frame parts arranged in the area of the center stop being assembled from Schenkein, which is parallel to the surfaces of the fire protection window extend from one of the narrow end faces of the fire protection window opposite bridge between the two legs, and also from a stop bar arranged essentially at right angles to the web.

Derartige Glastüren finden sowohl einzeln als auch als Türelement innerhalb einer aus mehreren Glasflächen zusammengesetzten Brandschutzverglasung Anwendung. Gemäß der deutschen Industrienorm DIN 4102 Teil 13 sind Brandschutzverglasungen der Feuerwiderstandsklasse F sowie der Feuerwiderstandsklasse G bekannt, und in den jeweils gestellten Anforderungen erläutert. Die Brandschutzscheiben sind häufig mehrlagig aus Glasscheiben mit einer dazwischen angeordneten Brandschutzschicht aufgebaut. Im Brandfall wird ein in dieser Brandschutzschicht enthaltener Schutzwirkstoff aktiviert, wodurch die Brandschutzscheibe Wärmestrahlung absorbiert und eine hochwirksame Dämmschicht bildet. Hiermit geht eine Trübung der Brandschutzscheibe einher, so daß aus der ursprünglich transparenten Verglasung eine praktisch undurchsichtige Feuerschutzwand wird. Such glass doors are found both individually and as a door element within fire protection glazing composed of several glass surfaces Application. According to the German industry standard DIN 4102 part 13 Fire protection glazing of fire resistance class F and fire resistance class G known and explained in the respective requirements. The fire protection panes are often made of multiple layers of glass panes with a fire protection layer arranged in between. In case of fire a protective agent contained in this fire protection layer is activated, whereby the fire protection window absorbs heat radiation and a highly effective Insulating layer forms. This causes the fire protection glass to become cloudy hand in hand, so that from the originally transparent glazing practically opaque fire protection wall.

Brandschutzscheiben sind ausgesprochen empfindlich gegen mechanische Beanspruchung. Dies gilt ganz besonders für die Stirnflächen der Brandschutzscheiben. Aber auch in brandschutztechnischer Hinsicht werden an die Rahmenkonstruktion höhere Anforderungen als bei herkömmlichen Glastüren gestellt. Insbesondere darf die Wärmeleitung durch die Türprofile keine zu großen Werte aufweisen.Fire protection panes are extremely sensitive to mechanical stress. This applies particularly to the end faces of the fire protection panes. But also from a fire protection point of view Frame construction has higher requirements than conventional glass doors posed. In particular, the heat conduction through the door profiles must not have great values.

Der Erfindung liegt die Aufgabe zugrunde, eine doppelflügelige Glastür mit Mittelanschlag für Brandschutzzwecke zu schaffen, mit der sich im Brandfall vergleichsweise niedrige Temperaturen auf der dem Brandherd abgewandten Seite erzielen lassen.The invention has for its object to provide a double-leaf glass door with a central stop for fire protection purposes, with which comparatively low temperatures can be achieved on the side facing away from the source of the fire in the event of a fire.

Zur Lösung dieser Aufgabe wird bei einer Glastür der eingangs genannten Art vorgeschlagen, daß die Anschlagleiste einen durch Verformen eines langgestreckten Metallstreifens gebildeten Hohlraum aufweist.To solve this problem it is proposed in a glass door of the type mentioned that the stop bar has a cavity formed by deforming an elongated metal strip.

Eine solche Glastür läßt sich mit einem relativ geringen Montageaufwand erstellen. Der bei herkömmlichen Glastüren für Brandschutzzwecke in der Regel besonders kritische Wärmeübergang im Bereich der Anschlagleiste wird deutlich reduziert, indem die Anschlagleiste mit einem während des Verformungsprozesses des Metallstreifens gebildeten Hohlraum versehen ist. Die so gebildete Anschlagleiste ist gleichsam doppelwandig geformt, wobei die außenliegende, sich im Brandfall besonders stark erhitzende Wand der Anschlagleiste nur mittelbar über die innenliegende Wand der Anschlagleiste mit dem Rahmeninneren in wärmeleitender Verbindung steht. Auf diese Weise wird im Brandfall eine Reduzierung der Wärmeleitung von der einen Seite der Glastür auf deren andere Seite erreicht.Such a glass door can be created with relatively little assembly effort. As a rule with conventional glass doors for fire protection purposes Particularly critical heat transfer in the area of the stop bar becomes clear reduced by the stop bar with a during the deformation process of the metal strip formed cavity is provided. The so educated The stop bar is of double-walled design, with the outer, wall of the stop bar that heats up particularly strongly in the event of fire only indirectly over the inside wall of the stop bar with the inside of the frame is in a thermally conductive connection. In this way In case of fire a reduction in heat conduction from one side of the glass door reached on their other side.

Nach demselben Prinzip läßt sich auch der Wärmeübergang in den beiden Schenkeln der Rahmenteile vermindern. Hierzu weisen vorzugsweise auch die beiden Schenke! jeweils einen durch Verformen eines langgestreckten Metallstreifens gebildeten Hohlraum auf. The heat transfer in the two can be done according to the same principle Reduce the legs of the frame parts. To this end, the both tavern! one by deforming an elongated metal strip formed cavity.

Um die infolge von Wärmeleitung übertragene Wärme weiter zu reduzieren, kann der Hohlraum mit einem unter Hitzeeinwirkung kühlenden Brandschutzmittel gefüllt sein.To further reduce the heat transferred due to heat conduction, The cavity can be filled with a fire protection agent that cools under heat be filled.

Mit der Erfindung wird ferner vorgeschlagen, daß an dem Metallprofil der Steg, der zumindest eine der beiden Schenkel und die Anschlagleiste ausgebildet sind. Auf diese Weise läßt sich der Montageaufwand beim Erstellen der Glastür verringern. Zudem sind für die Montage weniger Einzelteile erforderlich als bei den bekannten Glastüren für denselben Einsatzzweck.With the invention it is also proposed that on the metal profile Web formed at least one of the two legs and the stop bar are. In this way, the assembly effort when creating the Reduce the glass door. In addition, fewer individual parts are required for assembly than with the known glass doors for the same purpose.

Von zusätzlichem Vorteil ist es, wenn das Metallprofil ein Metallstreifen ist, an dem durch mehrfaches Verformen der Steg, der zumindest eine der beiden Schenkel und, durch Verformen eines Abschnittes zwischen Steg und Schenkel, die Anschlagleiste ausgebildet ist. Ein solches Metallprofil kann mit geringem Aufwand aus einem vorhandenen Stahlblech durch mehrfaches Abkanten hergestellt werden.It is of additional advantage if the metal profile is a metal strip by repeatedly deforming the web, at least one of the two Leg and, by deforming a section between the web and the leg, the stop bar is formed. Such a metal profile can be low Effort from an existing steel sheet due to multiple folding getting produced.

Mit weiterer Ausgestaltung kann vorgesehen sein, daß auch ein weiteres Metallprofil ein mehrfach verformter Metallstreifen ist, und daß sich der an dem weiteren Metallprofil angeformte Schenke! aus zwei zueinander parallelen Abschnitten dieses Metallstreifens zusammensetzt, die am freien Ende des Schenkels über eine ein- oder mehrfache Umlenkung miteinander verbunden sind. Zur Vermeidung zusätzlicher Befestigungselemente für die im Bereich des Mittelanschlags der doppelflügeligen Glastür erforderliche Dichtung kann sich zwischen dem außenliegenden der beiden den Schenkel bildenden Abschnitte des weiteren Metallprofils und dem Steg ein Spalt befindet, in den eine Dichtung einsetzbar ist, insbesondere durch Einklemmen zwischen die einander gegenüberliegenden Stirnflächen von Abschnitt und Steg.With a further embodiment it can be provided that a further metal profile is a multiply deformed metal strip, and that the on the another metal profile molded on tavern! from two mutually parallel sections this metal strip, which at the free end of the Legs connected to each other via a single or multiple deflection are. To avoid additional fasteners for those in the area of The middle stop of the double-leaf glass door may require a seal between the outer of the two sections forming the leg the further metal profile and the web is a gap in which a seal can be used, in particular by pinching them between each other opposite end faces of section and web.

Zwecks Verbesserung der Montageeigenschaften wird schließlich vorgeschlagen, daß die rechteckige Brandschutzscheibe an allen vier Rändern mit Rahmenteilen versehen ist, von denen zur Vereinfachung der Montage zunächst drei Rahmenteile fest miteinander verbunden werden, dann die Brandschutzscheibe in den so gebildeten Teilrahmen eingeschoben wird und schließlich das noch fehlende letzte Rahmenteil befestigt wird. Finally, in order to improve the assembly properties, it is proposed that that the rectangular fire protection window on all four edges with frame parts is provided, of which initially to simplify assembly three frame parts are firmly connected, then the fire protection window is inserted into the subframe thus formed and finally the last missing frame part is attached.

The frame 5 sets itself out of frame parts 6, 7, 8, 9 along the upper and lower edges as well the vertical edges of the fire protection window 4 together. The frame parts 6, 7, and 8 each consist of one-piece metal profiles with identical Cross-section, whereas the frame part 9 forming the center stop each of the two glass doors made of two interconnected metal profiles is composed.

Einzelheiten der Verbindung zwischen Brandschutzscheibe und den Rahmenteilen sind in der Fig. 2 dargestellt. Bei der Brandschutzscheibe 4 handelt es sich um ein Spezialverbundglas, welches aus mehreren Glasscheiben 4a mit dazwischen angeordneten Brandschutzschichten 4b besteht. Im Brandfall werden diese Brandschutzschichten 4b aktiviert, wobei sie Wärmestrahlung absorbieren und so eine wirksame Dämmschicht bilden, welche den Durchgang von Feuer und Rauch verhindert. Dabei führt die Aktivierung der Brandschutzschichten 4b im Brandfall dazu, daß diese aufschäumen und eine Trübung annehmen, so daß eine praktisch undurchsichtige Feuerschutzwand entsteht. Details of the connection between the fire protection window and the frame parts are shown in FIG. 2. The fire protection pane 4 is is a special laminated glass which consists of several glass panes 4a there are fire protection layers 4b arranged between them. In case of fire these fire protection layers 4b are activated, giving off heat radiation absorb and thus form an effective insulation layer, which the passage prevented from fire and smoke. The activation of the fire protection layers leads 4b in the event of a fire causing them to foam and clouding assume that a practically opaque fire wall arises.

Die Rahmenteile 6, 7, 8, 9 bilden gemeinsam eine Tragkonstruktion für die Brandschutzscheibe 4. Hierzu sind die Rahmenteile 6, 7, 8 und 9 hinsichtlich ihres Querschnittes U-förmig gestaltet mit Schenkeln 10, 11, 12, die sich parallel zu den Flächen der Brandschutzscheibe 4 erstrecken, und einem Steg 13, 14 zwischen den beiden Schenkeln 10 bzw. 11 und 12, wobei der Steg 13 bzw. 14 der jeweiligen schmalen Stirnfläche 15 der Brandschutzscheibe 4 gegenüberliegt.The frame parts 6, 7, 8, 9 together form a support structure for the Fire protection window 4. For this purpose, the frame parts 6, 7, 8 and 9 are regarding of its cross section U-shaped with legs 10, 11, 12, which extend parallel to the surfaces of the fire protection pane 4, and a web 13, 14 between the two legs 10 or 11 and 12, the web 13 or 14 of the respective narrow end face 15 of the fire protection pane 4 opposite.

Abgesehen von dem gemeinsamen U-förmigen Aufbau aus mindestens einem Metallprofil unterscheiden sich die Rahmenteile 6, 7, 8 einerseits und das den Mittelanschlag 3 bildende Rahmenteil 9 andererseits. Jedes der Rahmenteile 6, 7, 8 besteht aus einem Metallprofil, welches durch mehrfaches Verformen eines einzelnen langgestreckten Metallstreifens hergestellt ist, an dem daher durch geeignetes Abkanten sowohl die beiden Schenkel 10 als auch der Steg 13 ausgebildet sind. Zudem sind die freien Enden der Schenkel 10 mit einer 180°-Falzung 16 versehen, wobei die Richtung der Falzung derart ist, daß die umgefalzten Flächen 17 unter Zwischenlage einer Silikonschicht 18 an den Randflächen der Brandschutzscheibe 4 flächig anliegen und dort mit der Brandschutzscheibe verkleben. Die 180°-Falzung 16 erleichtert die Montage der Glastür, da sich infolge der im Bereich der Falzung 16 abgerundeten Kanten die Brandschutzscheibe 4 besser mit ihrer Stirnfläche 15 in das Rahmenteil einsetzen läßt bzw. sich das Rahmenteil umgekehrt besser auf die Brandschutzscheibe aufsetzen läßt, was im folgenden noch näher erläutert werden wird.Apart from the common U-shaped structure made up of at least one Metal profile, the frame parts 6, 7, 8 differ on the one hand and that Middle stop 3 forming frame part 9 on the other hand. Each of the frame parts 6, 7, 8 consists of a metal profile, which by multiple deformation of a single elongated metal strip is made, on which therefore by suitable folding both the two legs 10 and the web 13 are formed. In addition, the free ends of the legs 10 with a 180 ° fold 16 provided, the direction of the fold is such that the folded surfaces 17 with the interposition of a silicone layer 18 on the Edge areas of the fire protection pane 4 lie flat and there with the Glue the fire protection window. The 180 ° fold 16 makes assembly easier the glass door, as a result of the rounded edges in the area of the fold 16 the fire protection pane 4 better with its end face 15 in the frame part can be used or the frame part conversely better on the fire protection window can be put on, which are explained in more detail below becomes.

Bei der Falzung 16 handelt es sich um eine enge Falzung, d.h. die nach innen umgefalzte Fläche 17 liegt unmittelbar an der nicht gefalzten Fläche des Schenkels 10 an. Ferner ist bei den Rahmenteilen 6, 7, 8 der Steg 13 mit einer nach innen zu der Stirnfläche 15 der Brandschutzscheibe 4 hin gerichteten Einbuchtung 19 versehen. Die Einbuchtung 19, die sich fast über die gesamte Breite des Stegs 13 erstreckt, dient der Aufnahme eines Streifens 20 aus einem unter Hitzeeinwirkung aufschäumenden Material. Da der Streifen 20 in der Einbuchtung 19 sitzt, ist er von außen nicht sichtbar und zudem vor mechanischen Verletzungen geschützt. Da der bei der Herstellung des Rahmenteils 6, 7, 8 verwendete Metallstreifen bei der Herstellung der Einbuchtung 19 zusätzlich verformt wird, verlängert sich der Weg, den die Wärme entlang des Steges 13 nehmen muß, so daß die Einbuchtung 19 auch in brandschutztechnischer Hinsicht Vorteile gegenüber einem geraden Verlauf des Steges hat.The fold 16 is a tight fold, i.e. the inside folded surface 17 lies directly on the unfolded surface of the Leg 10 on. Furthermore, in the frame parts 6, 7, 8, the web 13 with a directed towards the end face 15 of the fire protection pane 4 Indentation 19 provided. The indentation 19, which extends almost over the entire The width of the web 13 extends, is used to accommodate a strip 20 from a material foaming under the influence of heat. Since the strip is 20 in the recess 19 sits, it is not visible from the outside and also in front of mechanical Injuries protected. Because of the manufacture of the frame part 6, 7, 8 used metal strips in the manufacture of the recess 19 is deformed, the path that the heat along the Web 13 must take, so that the recess 19 also in fire protection Advantages compared to a straight course of the web Has.

Zwischen der Stirnfläche 15 der Brandschutzscheibe 4 und dem gegenüberliegenden Steg 13 befindet sich eine Fuge 21, in die im Brandfall der Schutzwirkstoff der Brandschutzschicht 4b unter Verschluß der Fuge austreten kann. Die Fuge zwischen Türrahmen und Türzarge 1 wird im Brandfall durch den unter Hitzeeinwirkung aufschäumenden Streifen 20 dicht verschlossen.Between the end face 15 of the fire protection window 4 and the opposite one Web 13 is a joint 21, in which the protective agent in the event of fire the fire protection layer 4b can escape with the joint sealed. The joint between the door frame and door frame 1 is in the event of fire by strips 20 foaming under the influence of heat are sealed.

Das in Fig. 2 weiter oben dargestellte Rahmenteil 9 im Bereich des Mittelanschlags 3 der zweiflügeligen Glastür ist, da zusätzlich eine Anschlagleiste 23 für den Mittelanschlag erforderlich ist, insgesamt voluminöser ausgebildet. Das Rahmenteil 9 setzt sich aus insgesamt zwei Metallprofilen 24, 25 zusammen, bei denen es sich jeweils um einen mehrfach verformten, langgestreckten Metallstreifen handelt. Die Hauptfunktion kommt hierbei dem Metallstreifen 24 zu. An diesem ist durch mehrfaches Biegen des Metallstreifens der eine Schenke 12, die Anschlagleiste 23 und der Steg 14 ausgebildet. Die Gestaltung ist gemäß Fig. 2 derart, daß, ausgehend von dem im wesentlichen ebenen Steg 14, sich hieran im rechten Winkel die Anschlagleiste 23 anschließt, die Anschlagleiste 23 anschließend über zwei gegensinnig rechtwinklige Abknickungen in den Schenkel 12 übergeht, der sich über die Stütz- und Dichtschicht 18 an dem einen Rand der Brandschutzscheibe 4 abstützt. Hierbei sind sowohl die Anschlagleiste 23 als auch der Schenkel 12 unter Einschließung eines Hohlraumes 26 bzw. 27 geformt. Zur Bildung dieses Hohlraumes 26 bzw. 27 ist das Metall an den Enden von Anschlagleiste 23 und Schenkel 12 nicht um 180° umgebogen, sondern jeweils zweifach um 90°. Die Hohlräume 26, 27 vermindern im Brandfall die Wärmebelastung des inneren Abschnitts des Schenkels 12 und der Anschlagleiste 23 und verbessern damit insgesamt die wärmetechnischen Eigenschaften des Rahmenteils 9. Im übrigen ist der Schenkel 12 gleichsinnig wie der Schenkel 10 der anderen Rahmenteile geformt, d.h. die umgeformte Fläche am Ende des Schenkels befindet sich innen und damit neben dem Scheibenrand. Die Hohlräume 26, 27 können mit einem bei Hitzeeinwirkung kühlenden Brandschutzmittel 34 gefüllt sein. The frame part 9 shown further above in FIG. 2 in the area of the center stop 3 of the double-leaf glass door, because there is also a stop bar 23 is required for the center stop, overall more voluminous. The frame part 9 is composed of a total of two metal profiles 24, 25, each of which is a multi-deformed, elongated Metal strip. The main function here is the metal strip 24 to. This is the one by multiple bending of the metal strip Tavern 12, the stop bar 23 and the web 14 are formed. The design 2 is such that, starting from the substantially flat Web 14, the stop bar 23 adjoins this at right angles, the stop bar 23 then over two mutually rectangular bends merges into the leg 12, which over the support and sealing layer 18 is supported on one edge of the fire protection window 4. Here are both the stop bar 23 and the leg 12 with inclusion a cavity 26 or 27 formed. To form this cavity 26 or 27 is the metal at the ends of stop bar 23 and leg 12 not bent by 180 °, but twice by 90 °. The cavities 26, 27 reduce the heat load on the inner section in the event of a fire of the leg 12 and the stop bar 23 and thus improve overall the thermal properties of the frame part 9. Otherwise Leg 12 shaped in the same direction as the leg 10 of the other frame parts, i.e. the reshaped surface at the end of the leg is inside and thus next to the edge of the pane. The cavities 26, 27 can with a when exposed to heat cooling fire protection agent 34 may be filled.

Der weitere Metallstreifen 25 hingegen, der ausschließlich der Formung des anderen Schenkels 11 dient, weist eine andere Richtung der Verformung auf. Ein erster Abschnitt 28 erstreckt sich parallel zu dem Steg 14 und ist fest mit diesem verbunden, an diesen ersten Abschnitt 28 schließt sich im rechten Winkel ein zweiter Abschnitt 29 an, der mittels der Stütz- und Dichtschicht 18 die Brandschutzscheibe 4 abstützt. Über zwei beabstandete 90°-Abwinklungen 30 schließt sich schließlich ein zu dem zweiten Abschnitt 29 paralleler dritter Abschnitt 31 an, der die Außenfläche des Schenkels 11 bildet. Auch der Schenkel 11 ist daher mit einem in wärmetechnischer Hinsicht vorteilhaften Hohlraum 27 versehen, und vorzugsweise mit Brandschutzmittel 34 gefüllt.The other metal strip 25, on the other hand, which is exclusively the formation of the serves other leg 11, has a different direction of deformation. A first section 28 extends parallel to the web 14 and is fixed with connected to this first section 28 is in the right Angle a second section 29, which by means of the support and sealing layer 18 supports the fire protection window 4. Over two spaced 90 ° bends 30 finally includes a parallel to the second section 29 third section 31, which forms the outer surface of the leg 11. Also the leg 11 is therefore advantageous in terms of heat technology Provided cavity 27, and preferably filled with fire retardant 34.

Die Verbindung zwischen den beiden Metallstreifen 24, 25 kann erfolgen, indem der erste Abschnitt 28 des Metallstreifens 25 mit dem am Metallstreifen 24 ausgebildeten Steg 14 verschweißt oder vernietet wird. Zwischen den freien Enden des Steges 14 und des dritten Abschnittes 31 verbleibt ein kleiner Spalt 32, in den sich eine Dichtung 33 einsetzen läßt, vorzugsweise durch Einklemmen in den Spalt.The connection between the two metal strips 24, 25 can be made by the first section 28 of the metal strip 25 with that on the metal strip 24 trained web 14 is welded or riveted. Between the free The ends of the web 14 and the third section 31 remain small Gap 32 into which a seal 33 can be inserted, preferably through Pinching in the gap.

Um den Wärmeübergang zwischen den beiden Metallstreifen 24, 25 zusätzlich zu erschweren, kann die Verbindung zwischen erstem Abschnitt 28 und Steg 14 mit einer thermischen Trennung versehen sein, z.B. durch Einsatz eines Isolierstreifens und einer punktweisen Verschweißung oder durch Verwendung von Nieten.In addition to the heat transfer between the two metal strips 24, 25 to complicate, the connection between the first section 28 and web 14 may be provided with a thermal break, e.g. by using a Insulating strip and a spot weld or by use of rivets.

Um den Hohlraum des Mittelanschlags 3 im Brandfall sicher zu verschließen, sind auf den Außenseiten der einander zugewandten Stege 14 wiederum Streifen 20 aus unter Hitze aufschäumendem Material angeordnet.In order to securely close the cavity of the center stop 3 in the event of a fire, are on the outside of the mutually facing webs 14 in turn Strips 20 of heat foaming material are arranged.

Die Montage der Glastür ist sehr einfach. Zunächst werden drei Rahmenteile der Rahmenkonstruktion, z.B. die Rahmenteile 6, 8 und 9, zu einem dreiseitigen Rahmen verschweißt. In die offene Seite dieses dreiseitigen Rahmens wird sodann die Brandschutzscheibe eingeschoben, wobei eine sichere Führung entlang der in Einschubrichtung angeordneten Rahmenteile erfolgt. Nachdem die Brandschutzscheibe in diesem dreiseitigen Rahmen fixiert ist, wird schließlich das vierte und letzte Rahmenteil, z.B. das Rahmenteil 7, auf den betreffenden Rand der Brandschutzscheibe aufgesteckt und mit den beiden benachbarten Rahmenteilen verschweißt oder verschraubt, wodurch der Rahmen komplett ist. The assembly of the glass door is very simple. First, three frame parts the frame construction, e.g. the frame parts 6, 8 and 9, to a three-sided Frame welded. In the open side of this three-sided frame then the fire protection window inserted, ensuring a safe guide takes place along the frame parts arranged in the direction of insertion. After this the fire protection window is fixed in this three-sided frame, eventually the fourth and last frame part, e.g. the frame part 7, on the relevant The edge of the fire protection window and the two neighboring ones Frame parts welded or screwed, creating the frame is complete.
