Abstract
Description
Die Erfindung betrifft ein Verfahren zum Herstellen eines Deckenauslasses, insbesondere eines quadratischen Deckenauslasses für das Einblasen von Zuluft aus einem Luftleitsystem in einen Raum mit aus einem Blech, einer Stahlblechplatte od. dgl. auf drei Seiten ausgestanzten und um eine Knicklinie in einem Winkel abgekanteten Luftleitblechen, sowie einen Deckenauslaß nach dem ersten Teil des Anspruchs 4.The invention relates to a method for producing a ceiling outlet, in particular a square ceiling outlet for blowing supply air from an air guidance system into a room with air baffles punched out on three sides from a sheet metal, a sheet steel plate or the like and bent at an angle by a folding line, and a ceiling outlet according to the first part of claim 4.
Deckenauslässe dieser Art sind bekannt und auf dem Markt vielfach angeboten. Diese Auslässe unterscheiden sich vor allem in der Größe und in der Anordnung der den Luftstrom leitenden Lamellen.Ceiling outlets of this type are known and widely offered on the market. These outlets differ primarily in the size and arrangement of the fins that conduct the air flow.
Es gibt beispielsweise Auslässe mit wenigen und breiten Lamellen oder andere mit vielen und dafür schmalen Lamellen. Des weiteren sind Auslässe bekannt, deren Lamellen fest angeordnet sind, während andere Lamellen besitzen, welche verstellbar sind. In ihrer Grundkonzeption, insbesondere in ihrer Bauweise, sind sich jedoch sowohl die verstellbaren als auch die fest angeordneten Auslässe ähnlich. Dabei sind vor allem die Auslässe mit relativ breiten Einströmflächen aus Einzelstücken gefertigt.For example, there are outlets with a few and wide slats or others with many and narrow slats. Furthermore, outlets are known, the slats of which are fixedly arranged, while others have slats which are adjustable. In your The basic concept, in particular in terms of its construction, however, both the adjustable and the fixed outlets are similar. Above all, the outlets with relatively wide inflow surfaces are made from individual pieces.
Die Einzelstücke bestehen aus einem Rahmen und den einzelnen, die Lamellen bildenden Einblasringen. Solche Einblasringe werden durch Zusammenschweißen von einzeln geformten, insbesondere gestanzten Stücken hergestellt. Die zusammengeschweißten Einblasringe werden dann in einem weiteren Arbeitsschritt entweder wieder durch Schweißung oder aber durch Schraubung od. dgl. innerhalb des Rahmens befestigt. Ein solches Verfahren ist nicht nur umständlich, zeitraubend und somit kostenintensiv, sondern es ist auch umweltbelastend und energieverschwendend.The individual pieces consist of a frame and the individual blowing rings that form the lamellae. Such blowing rings are produced by welding individually shaped, in particular stamped pieces. The welded blow-in rings are then fastened again in the work step either by welding or by screwing or the like within the frame. Such a process is not only cumbersome, time-consuming and therefore costly, but it is also polluting and wastes energy.
Umweltbelastend ist das Verfahren nicht nur durch die beim Schweißen entstehenden Gase, sondern vor allem auch durch die Art der zu wählenden Lackierung, die durch das Vorhandensein von Ecken, Kanten und Schweißnähten nur möglich ist.The process is not only polluting due to the gases generated during welding, but above all due to the type of paint to be selected, which is only possible due to the presence of corners, edges and weld seams.
Energieverschwendend ist das Verfahren einerseits durch die für die Schweißapparate notwendige Energie und zweitens durch die Energie für die bei diesen Arbeiten vorgeschriebenen Absaugeinrichtungen.The process is energy-wasting on the one hand due to the energy required for the welding apparatus and secondly due to the energy required for the suction devices prescribed for this work.
Neben den wirtschaftlichen Gesichtspunkten wegen der hohen Arbeitskosten sind vor allem auch die Umweltbelastung und die Energieverschwendung Faktoren, die in einer Zeit einer erhöhten Sensibilisierung für die Umwelt verbesserungswürdig sind.In addition to the economic aspects due to the high labor costs, environmental pollution and energy waste are factors that need to be improved in a time of increased awareness of the environment.
Ein Deckenauslaß der o.g. Art ist aus der EP-A 0 211 150 bekannt. Der dort gezeigte Drallauslaß besteht aus einem Zuluftstutzen und einer Drallscheibe. Die Drallscheibe ist eine kreisförmige Blechscheibe, die auf zylindrischen Randabschnitten des in die Raumdecke eingesetzten Zuluftstutzens aufgesetzt wird. Die Lamellen in dieser Drallscheibe sind längs einer radialen Seitenkante ausgestanzt und längs der anderen radialen Seitenkante so aus der Ebene der Drallscheibe herausgebogen, daß sie unter einem Winkel von etwa 45° gegen die Luftströmung in den Zuluftstutzen hineinragen.A ceiling outlet of the above type is known from EP-A 0 211 150. The swirl outlet shown there consists of an air inlet and a swirl disk. The swirl disc is a circular sheet metal plate, which is placed on cylindrical edge sections of the supply air spigot inserted in the ceiling. The lamellae in this swirl disk are punched out along a radial side edge and bent out of the plane of the swirl disk along the other radial side edge in such a way that they protrude at an angle of approximately 45 ° against the air flow into the supply air connector.
Der Erfinder hat sich zur Aufgabe gestellt, einen Deckenauslaß zu schaffen, der die Vorteile der auf dem Markt befindlichen Auslässe dieser Art besitzt, jedoch in einem Verfahren hergestellt werden kann, welches sich kostengünstiger, umweltschonender und energiesparender auswirkt.The inventor has set himself the task of creating a ceiling outlet which has the advantages of the outlets of this type on the market, but which can be produced in a process which has a more cost-effective, environmentally friendly and energy-saving effect.
Zur Lösung dieser Aufgabe führt, daß ein Blech in der Größe des späteren Deckenauslasses zzgl. von Randstreifen zugeschnitten wird, daß das Blech geschlitzt und ausgeeckt wird, wobei die Schlitze zumindest drei Seiten von den Luftleitblechen umschreiben, daß in einer weiteren einzigen Arbeitsstufe die Luftleitbleche um die Knicklinie, welche der vierten Seite der umschreibenden Form des Luftleitbleches entspricht, hochgestellt und um den Winkel abgewinkelt sowie Randstreifen um Knicklinien, welche die Konturen des fertigen Deckenauslasses beschreiben, abgekantet werden.The solution to this problem is that a sheet is cut to the size of the future ceiling outlet plus edge strips, that the sheet is slit and licked out, the slots circumscribing at least three sides of the air baffle, that in a further single working step the air baffle the fold line, which corresponds to the fourth side of the circumscribing shape of the air baffle, is raised and angled by the angle, and edge strips are bent around fold lines, which describe the contours of the finished ceiling outlet.
Der Vorteil eines solchen Deckenauslasses besteht darin, daß er aus einem einzigen Stück ohne Schweißungen, Klebungen od. dgl. hergestellt werden kann.The advantage of such a ceiling outlet is that it can be made from a single piece without welding, gluing or the like.
Der erfindungsgemässe Deckenauslaß ist im Anspruch 4 beansprucht. Zur Herstellung wird ein Stahlblech, ein Blech od. dgl. bzw. eine Platte eines gewünschten Materials benötigt, welches in ihren Konturen der Form des späteren Deckenauslasses entspricht, wobei randseitig noch so viel Material zugelassen wird, wie für die spätere Abkantung der Randstreifen notwendig ist.The ceiling outlet according to the invention is claimed in claim 4. A steel sheet, a sheet metal or the like or a plate of a desired material is required for production, which corresponds in its contours to the shape of the future ceiling outlet, with so much still on the edge Material is permitted, as is necessary for the later folding of the edge strips.
Dieses Blech wird dann mittels eines besonderen und speziellen Fertigungsverfahrens, insbesondere durch Stanzung, geschlitzt und ausgeeckt. Die Konturen der Schlitze umschreiben dabei zumindest drei Seiten der Form der späteren abgewinkelten Luftleitbleche. Luftleitbleche dieser Art haben bevorzugt eine etwa gleichschenklig trapezförmige Kontur. Die Größe der Auseckung richtet sich nach der Größe der vorgesehenen Randstreifen.This sheet is then slit and licked using a special and special manufacturing process, in particular by punching. The contours of the slots circumscribe at least three sides of the shape of the later angled air baffles. Air baffles of this type preferably have an approximately isosceles trapezoidal contour. The size of the cover depends on the size of the edge strips provided.
In einem weiteren Arbeitsschritt nach der Erfindung findet die Abkantung der Randstreifen um entsprechende Knicklinien statt.In a further working step according to the invention, the edge strips are bent over corresponding folding lines.
Des weiteren werden in diesem Arbeitsschritt wiederum mit einem speziell dafür hergestellten Werkzeug die Luftleitbleche hochgestellt und in einem vorher bestimmten Winkel um eine Knicklinie, welche der langen Seite eines Trapezes entspricht, abgewinkelt. Das Spezialwerkzeug für die Abwinkelung der Luftleitbleche kann so eingestellt werden, daß Deckenauslässe mit mehr oder weniger starken abgewinkelten Luftleitblechen herstellbar sind.Furthermore, in this step, the air baffles are raised again using a specially manufactured tool and angled at a predetermined angle around a crease line, which corresponds to the long side of a trapezoid. The special tool for bending the air baffles can be set so that ceiling outlets can be manufactured with more or less strong angled air baffles.
Es ist denkbar, daß im ersten Arbeitsschritt bei der Schlitzung und Stanzung der Bleche gleichzeitig auch Löcher für die Aufnahme von Befestigungselementen eingebracht werden können.It is conceivable that, in the first step in the slitting and punching of the sheets, holes can also be made for receiving fastening elements.
Ein solches Verfahren zur Herstellung von Deckenauslässen ist sehr schnell und dadurch kosten- und energiesparend. Durch den Wegfall von Schweiß- oder Klebarbeiten ist dieses Verfahren auch in hohem Maße umweltschonend. Des weiteren sind Auslässe dieser Art aufgrund ihrer Bauweise pulverbeschichtbar. Gegenüber der bisherigen Sprühlackierung stellt dieses Verfahren des weiteren eine Verminderung der Umweltbelastung dar als auch eine qualitative Aufwertung eines entsprechenden Auslasses.Such a process for the production of ceiling outlets is very fast and therefore saves costs and energy. Because there is no welding or adhesive work, this process is also very environmentally friendly. Furthermore, outlets of this type can be powder-coated due to their construction. Compared to the previous spray painting, this process also represents a reduction in environmental pollution and a qualitative upgrade of a corresponding outlet.
