Description

Die Erfindung betrifft ein kanalförmiges Gehäuse für eine Absperrvorrichtung in Lüftungsleitungen, eine Absperrvorrichtung mit demselben und ein Verfahren zur Herstellung desselben.The invention relates to a channel-shaped housing for a shut-off device in ventilation ducts, a shut-off device with the same and a method for producing the same.

Gehäuse von Absperrvorrichtungen, wie z. B. Brandschutzklappen, in Lüftungsleitungen sind in der Regel aus mindestens vier bis acht einzelnen Rahmenteilen zusammengesetzt. Die Gehäuse sind damit in der Regel in Längsrichtung 1- bis 2-stückig und Umfangsrichtung 4- bis 8-stükkig.Housing of shut-off devices, such. As fire dampers in ventilation ducts are usually composed of at least four to eight individual frame parts. The housing are thus usually in the longitudinal direction 1- to 2-piece and circumferential direction 4- to 8 -stükkig.

Das Montieren der einzelnen Rahmenteile ist mit entsprechendem Aufwand verbunden. Ferner sind bei der Vielzahl der erforderlichen Verbindungsstellen (vier bis acht Längsnähte plus vier Stoßnähte bei 2-stückigen Gehäusen) vermehrt Leckageprobleme zu erwarten, welche im Nachhinein durch Auftragen von Dichtungsmitteln beseitigt werden müssen.The mounting of the individual frame parts is associated with the corresponding effort. Furthermore, in the large number of required joints (four to eight longitudinal seams plus four butt welds in 2-piece housings) increased leakage problems are expected, which must be eliminated in retrospect by applying sealants.

DE-A-3402814 offenbart ein Beispiel eines Gehäuses für eine Absperrvorrichtung. DE-A-3402814 discloses an example of a housing for a shut-off device.

Der Erfindung liegt somit die Aufgabe zugrunde, ein gattungsgemäßes Gehäuse bereitzustellen, das weniger aufwendig und damit kostengünstiger herstellbar ist.The invention is therefore based on the object to provide a generic housing, which is less expensive and therefore less expensive to produce.

Erfindungsgemäß wird diese Aufgabe mit dem Gehäuse gemäß Anspruch 1 gelöst.According to the invention this object is achieved with the housing according to claim 1.

Zudem wird diese Aufgabe gelöst durch eine Absperrvorrichtung mit einem kanalförmigen Gehäuse nach Anspruch 1.In addition, this object is achieved by a shut-off device with a channel-shaped housing according to claim 1.

Weiterhin wird diese Aufgabe dem Verfahren gemäß Anspruch 14 gelöst.Furthermore, this object is achieved by the method according to claim 14.

Dabei kann das Gehäuse durch eine Fügeverbindung im Bereich der Längsnaht geschlossen sein.In this case, the housing may be closed by a joint connection in the region of the longitudinal seam.

Insbesondere kann vorgesehen sein, daß die Fügeverbindung eine Punktfüge-, Schweiß-, Schraub-, Niet- oder Klebeverbindung ist.In particular, it can be provided that the joint connection is a Punktfüge-, welding, screwing, riveting or adhesive connection.

Außerdem kann vorgesehen sein, daß es mindestens eine sich entlang seiner Seiten erstreckende Außensicke in einer zur ersten Ebene parallelen Ebene aufweist.In addition, it can be provided that it has at least one outer bead extending along its sides in a plane parallel to the first plane.

Günstigerweise sind Eckbleche derart in die Außensicke eingelegt und durch eine Fügeverbindung daran befestigt, daß sie in den Eckbereichen nach außen vorragen.Conveniently, corner plates are inserted into the outer bead and secured thereto by a joint connection, that they project outwardly in the corner regions.

Günstigerweise ist an jedem Ende des Gehäuses ein Anschluß ausgebildet. Dies ermöglicht ein Verbinden des Gehäuses mit einer Lüftungsleitung.Conveniently, a terminal is formed at each end of the housing. This allows a connection of the housing with a ventilation duct.

Vorteilhafterweise ist mindestens ein Anschluß als ein Flansch ausgebildet.Advantageously, at least one connection is designed as a flange.

Zweckmäßigerweise sind die Flansche in den Eckbereichen über Eckbleche miteinander verbunden.Conveniently, the flanges are connected to each other in the corner areas by gussets.

Vorteilhafterweise sind die Eckbleche über eine Fügeverbindung befestigt. Bei der Fügeverbindung kann es sich beispielsweise um eine Punktfüge-, Schweiß-, Schraub-, Niet- oder Klebeverbindung handeln.Advantageously, the corner plates are fastened via a joint connection. The joint connection can be, for example, a point joint, welding, screwing, riveting or adhesive connection.

Vorteilhafterweise weisen die Eckbleche in deren Eckbereichen mindestens ein Längsloch auf.Advantageously, the corner plates have at least one longitudinal hole in their corner regions.

Gemäß einer weiteren besonderen Ausführungsform der Erfindung kann vorgesehen sein, daß in das Gehäuse eine Lagerbuchse für einen Schließhebel und eine Lagerbuchse für einen Stellhebel eingesetzt ist. Der Stell- und Schließhebelmechanismus dient dabei dazu, ein Klappenblatt, welches den Verschluß bewirkt, in Öffnungslage zu halten, wobei er im Brandfalle durch eine thermische Auslösung automatisch ein Schließen des Klappenblattes bewirken soll. Der Stell- und Schließhebelmechanismus dient auch dazu, das Klappenblatt der Absperrvorrichtung von Hand oder per Auslöseeinrichtung in eine Schließstellung bringen zu können, ohne gleichzeitig die thermische Auslösung mitzubetätigen.According to another particular embodiment of the invention can be provided that in the housing a bearing bush is used for a locking lever and a bearing bush for a lever. The adjusting and closing lever mechanism serves to hold a damper blade, which causes the shutter to be in the open position, whereby it should automatically cause a closing of the damper blade in case of fire by a thermal tripping. The adjusting and closing lever mechanism also serves to be able to bring the damper blade of the shut-off device by hand or by triggering device in a closed position without mitzubetätigen the thermal release.

Dies bedeutet nichts anders, als daß die Lagerung des Schließhebels und die des Stellhebels im Gehäuse erfolgt, wodurch man eine Schließ- und eine Stellachse erhält. Bei bekannten Brandschutzklappen sind die Schließachse und Stellachse auf zwei Bauteilen untergebracht, die deshalb bei der Montage oder einer eventuellen Demontage zusammengesetzt (-geführt) werden müssen. Dies erschwert bei den bekannten Brandschschutzklappen einen exakten Verlauf des Klappenblattes einer Brandschutzklappe bzw. die exakte Schließstellung. Gegebenenfalls muß sogar ausgerichtet werden.This means nothing else than that the storage of the closing lever and the adjusting lever takes place in the housing, thereby obtaining a closing and a control axis. In known fire dampers, the locking axis and adjusting axis are housed on two components, which must therefore be assembled during assembly or a possible disassembly (-gef). This complicates in the known fire protection flaps an exact course of the damper blade of a fire damper or the exact closed position. If necessary, even must be aligned.

Die Verfahrensunteransprüche betreffen vorteilhafte Weiterbildungen des erfindungsgemäßen Verfahrens.The method subclaims relate to advantageous developments of the method according to the invention.

Der Erfindung liegt die überraschende Erkenntnis zugrunde, daß durch die spezielle einstückige Ausbildung des Gehäuses kaum manuelle Tätigkeiten erforderlich sind und nur ein einmaliges Fügen einer sich in Längsrichtung erstreckender Fügenaht für einen Gehäuseschluß erforderlich ist. Dies ermöglicht eine größenteils vollautomatische und damit günstige Herstellung.The invention is based on the surprising finding that hardly any manual operations are required by the special one-piece design of the housing and only a single joining a longitudinally extending joint seam is required for a housing closure. This allows a largely fully automatic and thus cheap production.

Ferner besteht das Gehäuse aus einer geringeren Anzahl von Einzelteilen, da es aus einer einzigen, gefalteten Platine anstatt überlicherweise mindestens vier bis acht Platinen herstellbar ist.Furthermore, the housing consists of a smaller number of individual parts, since it can be produced from a single, folded board instead of usually at least four to eight boards.

Weiterhin ergibt sich eine höhere Gehäusedichtigkeit und damit geringere (Gehäuse)- Leckagemenge aufgrund weniger Teile als bisher. So fallen drei (bei in Längsrichtung 1-stückigen Gehäusen) bis sieben (bei in Längsrichtung 2-stückigen Gehäusen) Längsnahtverbindungen weg. Bei in Längsrichtung 2-stückigen Gehäusen fallen darüber hinaus vier Stoßverbindungen in Längsrichtung weg.Furthermore, there is a higher housing density and thus lower (housing) - leakage due to fewer parts than before. Thus, three fall (in the longitudinal 1-piece housings) to seven (with longitudinally 2-piece housings) longitudinal seam joints away. In the case of longitudinal 2-piece housings also fall four joints in the longitudinal direction away.

Außerdem ist für einen exakten Verlauf des Klappenblattes bzw. für eine exakte Schließstellung kein Ausrichten wie bei einer zwei- oder mehrteiligen Bauweise erforderlich.In addition, no alignment is required for an exact course of the damper blade or for an exact closed position as in a two- or multi-part design.

Wenn gemäß einer besonderen Ausführungsform der Erfindung an beiden Enden des Gehäuses im Bereich der Innensicke v-förmige Prägungen vorgesehen sind, so läßt sich daraus eine verhakende und verschießbare Falz bilden, wodurch eine Längsnahtverbindung ohne Zuhilfenahme von weiteren Formteilen möglich wird.If according to a particular embodiment of the invention in the region of the inner bead v-shaped embossments are provided at both ends of the housing, then it can form a verhakende and verschießbare fold, whereby a longitudinal seam connection without the aid of other moldings is possible.

Bei einer weiteren besonderen Ausführungsform der Erfindung, bei der v-förmige Prägungen im Bereich der Innensicke entlang den späteren Biegelinien vorgesehen sind, liegt darüber hinaus der Vorteil vor, daß zum Umformen der nicht auf der Biegelinie befindliche Innensicke keine Durchbrüche und weitere Formteile zum Verschließen derselben Zuhilfe genommen werden müssen.In a further particular embodiment of the invention, in which V-shaped embossments are provided in the region of the inner bead along the later bending lines, there is also the advantage that for forming the not located on the bending line inner bead no openings and other moldings for closing the same Must be taken.

Weitere Merkmale und Vorteile der Erfindung ergeben sich aus den Ansprüchen und der nachstehenden Beschreibung, in der ein Ausführungsbeispiel anhand der schematischen Zeichnungen im einzelnen erläutert ist. Dabei zeigen:

Gemäß einer besonderen Ausführungsform läuft das Verfahren zur Herstellung des Gehäuses im wesentlichen wie folgt ab:According to a particular embodiment, the method of manufacturing the housing proceeds essentially as follows:

Aus Spaltband wird zunächst eine flache Platine mit Stanzungen mittels Stanzen und Ablängen erstellt.From slit strip, first of all, a flat board with punchings by means of punching and cutting to length is created.

Das Profil des späteren Gehäuses wird anschließend mittels Profilumformen (Kanten, Biegen und Profilieren) der gestanzten Platine erzeugt.The profile of the later housing is subsequently produced by means of profile forming (edges, bending and profiling) of the stamped blank.

Durch Prägen von Verschluß-, Knick- und Endprägungen der so profilumgeformten Platine entstehen Biegelinien, entlang derer die Platine zu einem Gehäuse geformt wird.By embossing of closure, buckling and end embossing of the so profilumgeformten board bend lines are formed, along which the board is formed into a housing.

Anschließend wird das Gehäuse entlang der noch offenen Längsnaht durch eine Fügeverbindung geschlossen.Subsequently, the housing is closed along the still open longitudinal seam by a joint connection.

Zur Komplettierung des Gehäuses werden im Bereich der Flansche und im Bereich der Außensicken Eckbleche eingelegt und gefügt.To complete the housing, corner plates are inserted and joined in the area of the flanges and in the area of the outside beads.

Figur 1 zeigt eine Draufsicht auf eine flache Platine 100. Die flache Platine 100 wird mit allen erforderlichen Stanzungen aus Spaltband hergestellt. Die Stanzungen umfassen die Außenkontur, Langlöcher 2 für ein (späteren) Anschluß einer Lüftungleitung (Anschlußseite ist durch 1 gekennzeichnet), Schlitze 3 zum (späteren) Anbringen von Eckblechen im Bereich eines Flansches der Brandschutzklappe, Löcher 4 zur (späteren) Befestigung einer Montageplatte mit einer Antriebs- und Auslöseeinrichtung, Löcher 5 zur Durchführung und Befestigung der Auslöseeinrichtung, Löcher 6 zur Befestigung einer Lagerplatte, Löcher 7 für Revisionsöffnungen, Löcher 8 zur Befestigung eines Deckblechs, eine Öffnung 9 für einen Antrieb, Schlitze 10 zum (späteren) Einlegen von Eckblechen im Bereich von Außensicken und Durchzüge 11 für eine Achslagerung des Klappenblattes der Brandschutzklappe. Weiterhin sind mit BL Biegelinien gekennzeichnet. Es handelt sich dabei lediglich um zeichnerische Linien. FIG. 1 shows a plan view of a flat circuit board 100. The flat board 100 is made with all required cuts from slit strip. The punches include the outer contour, slots 2 for a (later) connection of a ventilation line (terminal side is indicated by 1), slots 3 for (later) attaching corner plates in the region of a flange of the fire damper, holes 4 for (later) mounting a mounting plate with a driving and triggering device, holes 5 for carrying and fixing the triggering device, holes 6 for mounting a bearing plate, holes 7 for inspection openings, holes 8 for attachment of a cover plate, an opening 9 for a drive, slots 10 for (later) inserting corner plates in the range of outer beads and passages 11 for a journal bearing of the damper blade of the fire damper. Furthermore, BL are marked with bending lines. These are merely drawing lines.

Die Schlitze 3 und 10 sind derart ausgebildet, daß an den jeweiligen beiden Enden von drei direkt benachbarten geradlinigen späteren Biegelinien BL jeweils einer der Schlitze 3 zum späteren Befestigen von Eckblechen angeordnet und zwischen beiden Enden jeder Biegelinie BL jeweils zwei Schlitze 10 zum späteren Einlegen von Eckblechen beabstandet angeordnet sind.The slots 3 and 10 are formed such that at the respective two ends of three directly adjacent rectilinear later bending lines BL each one of the slots 3 arranged for later fixing corner plates and between two ends of each bending line BL two slots 10 for later insertion of corner plates spaced apart.

Die gestanzte Platine 100 wird nach dem Ablängen einer Profilformung unterzogen.The punched board 100 is subjected to profile cutting after being cut to length.

Es werden Außensicken 12, eine Innensicke 14 im mittleren Bereich und ein Doppelumschlag 16 an beiden Seiten geformt. Das Ergebnis ist in den Figuren 2a bis 2c gezeigt. Figur 2a zeigt eine Draufsicht auf die fertig geformte Platine 100, Figur 2b zeigt eine Seitenansicht der Platine von Figur 2a und Figur 2c zeigt eine Detailansicht (Detail Y) von Figur 2b.External beads 12, an inner bead 14 in the middle region and a double envelope 16 are formed on both sides. The result is in the FIGS. 2a to 2c shown. FIG. 2a shows a plan view of the finished shaped board 100, FIG. 2b shows a side view of the board of FIG. 2a and Figure 2c shows a detail view (detail Y) of FIG. 2b ,

Zum Herstellen der für das spätere Aufrichten des Gehäuses aus der Platine erforderlichen Prägungen werden vier v-förmige Prägungen 18, 20, 22 und 24 und eine Prägung 26 erstellt, die eine Hälfte der Prägung 18 darstellt. Die Prägung 18 stellt eine Verschlußprägung dar und bildet zusammen mit der Prägung 26 später eine sich verhakende und verschließbare Falz. Alle fünf Prägungen 18 bis 26 liegen im Bereich der (späteren) Innensicke 14. Die Prägungen 18 bis 24 weisen einen Winkel α von 90° auf und sorgen dafür, daß sich beim nachfolgenden Umformen der Platine 100 zum Aufrichten eines Gehäuses geradlinige Biegelinien ergeben. Aufgrund der Schlitze 3 und 10 sind die Außensicken 12 und Flansche 28 und 30 sowie die späteren Anschläge geschlitzt und erlauben das nachfolgende Biegen entlang der Biegelinien BL. Figur 3 zeigt das aus der Platine 100 resultierende Profil.In order to produce the embossments required for the subsequent erection of the housing from the board, four V-shaped embossings 18, 20, 22 and 24 and an embossment 26 are created which represent one half of the embossment 18. The embossment 18 represents a closure embossing and forms together with the embossing 26 later a hooking and closable fold. All five embossments 18 to 26 are in the region of the (later) inner bead 14. The embossments 18 to 24 have an angle α of 90 ° and ensure that the subsequent forming of the circuit board 100 for erecting a housing results in linear bending lines. Due to the slots 3 and 10, the outer beads 12 and flanges 28 and 30 and the later stops are slotted and allow subsequent bending along the bending lines BL. FIG. 3 shows the profile resulting from the board 100.

Dieses Profil wird entlang den vier Biegelinien BL umgeformt. Nach dem vollständigen Biegen wird die Prägung 26 in den Umschlag der Prägung 18 eingefädelt. Die Figur 4 zeigt oben den Biegeprozeß und das Schließen des kanalförmigen Gehäuses im Bereich außerhalb der Innensicke 14 und unten den Biegeprozeß und das Schließen des kanalförmigen Gehäuses im Bereich der Innensicke 14. Die Positionen entsprechen dabei den Konturen in den Schnitten C-C und D-D von Figur 5a. Das resultierende Gehäuse weist nunmehr im Bereich der Innensicke 14 an allen vier Ecken Ecklaschen 15 (siehe Figur 5a und 5c) auf.This profile is reshaped along the four bending lines BL. After complete bending, the embossment 26 is threaded into the envelope of the embossment 18. The FIG. 4 shows above the bending process and the closing of the channel-shaped housing in the area outside the inner bead 14 and below the bending process and the closing of the channel-shaped housing in the region of the inner bead 14. The positions correspond to the contours in the sections CC and DD of FIG. 5a , The resulting case has now in the area of the inner bead 14 at all four corners corner tabs 15 (see FIGS. 5a and 5c ) on.

Zum Schließen des Gehäuses wird eine einmal pro Gehäuse erforderliche Fügeverbindung der offenen Längsnaht z. B. durch Fügen hergestellt.To close the housing is required once per housing joint connection of the open longitudinal seam z. B. made by joining.
