Description

"Vorrichtung zur Aufhängung von Luftkanälen""Device for the suspension of air ducts"
Die Erfindung richtet sich auf eine Vorrichtung zur Befe¬ stigung von aus einzelnen Kanalschüssen zusammengesetzten Luftkanälen der im Oberbegriff des Anspruches 1 angegebenen Gattung (EP-B-0 085 355).The invention is directed to a device for fastening air ducts composed of individual duct sections of the type specified in the preamble of claim 1 (EP-B-0 085 355).
Es ist bekannt, Luftkanäle aus einzelnen Schüssen bauseits zusammenzustellen, wobei die Stirnseiten der Kanalschüsse mit Rahmenprofilen versehen sind, die in ihren Eckbereichen unter Zwischenlage einer Fugendichtung zusammengeschraubt werden können (DE-C-27 58 295). Dabei ist es auch bekannt, diese Rahmenprofile mit außenrandseitigen Abkröpfungen zu versehen, die von C-förmigen Schiebeleisten oder entspre¬ chend geformten Spannklammern übergriffen werden können, um die einzelnen Kanalschüsse luftdicht zusammenzuhalten, wie z.B. aus der US-3 199 901, der DE-C-35 12 669 oder der DE- C-37 10 665 hervorgeht.It is known to assemble air ducts from individual shots on site, the end faces of the duct shots being provided with frame profiles which can be screwed together in their corner regions with the interposition of a joint seal (DE-C-27 58 295). It is also known to provide these frame profiles with offsets on the outer edge, which can be overlapped by C-shaped sliding strips or correspondingly shaped clamps in order to hold the individual channel sections airtight, such as e.g. from US-3 199 901, DE-C-35 12 669 or DE-C-37 10 665.
In der Regel werden derartige Lüftungskanäle beim Decken von Gebäuden, Tiefgaragen u. dgl. aufgehängt, wobei es be¬ kannt ist, an Gewindestangen befindliche Traversen unter¬ halb der Luftkanäle hindurchzuziehen und diese Traversen an den Gewindestangen aufzuhängen. Aus der DE-B-22 65 555 ist es bekannt, die Eckwinkel zur Aufhängung heranzuziehen. Auch ist es bekannt, seitlich oder an den unteren Eckberei chen Aufhängerösen oder -laschen zu befestigen, in die dan Gewindestangen eingreifen können, die nach oben weisend zu Befestigung herangezogen werden.As a rule, such ventilation ducts when ceilings in buildings, underground garages and. Like. Suspended, it being known to pull traverses located on threaded rods below the air ducts and to hang these traverses on the threaded rods. From DE-B-22 65 555 it is known to use the corner brackets for the suspension. It is also known to attach laterally or to the lower corner areas Chen suspension loops or tabs, in which dan threaded rods can engage, which are used upward pointing for attachment.
Das Auflegen der Luftkanäle auf Traversen, die ihrerseits dann an Gebäudedecken od. dgl. befestigt sind, ist ver¬ gleichsweise kostenaufwendig, da die Aufhängemittel, z.B. die Gewindestangen, in jedem Falle deutlich länger sein müssen als die Kanalhöhe, die Aufhängung von zusätzlich angebrachten Befestigungslaschen hat u.a. den Nachteil, da im Befestigungsbereich der Laschen Undichtigkeiten auftre¬ ten können, werden die Laschen durch Chromschweißung be¬ festigt, kann es nicht nur zur Korrosionen kommen, es muß ein zusätzlicher Montageaufwand getrieben werden.Placing the air ducts on trusses, which in turn are then attached to building ceilings or the like, is comparatively expensive because the suspension means, e.g. the threaded rods, in any case, must be significantly longer than the channel height, the attachment of additional fastening tabs has, among other things. the disadvantage that leaks can occur in the fastening area of the straps, the straps are fastened by chromium welding, not only can there be corrosion, an additional assembly effort must be made.
Aufgabe der Erfindung ist die Schaffung einer Befestigungs vorrichtung, die einfach zu montieren ist, mit der gleich¬ zeitig die Aufhängungsmittel erheblich verkürzt werden kön nen, so daß es zu entsprechenden Materialersparnissen kommt.The object of the invention is to provide a fastening device which is easy to assemble, with which the suspension means can be considerably shortened at the same time, so that corresponding material savings are achieved.
Mit einer Vorrichtung der eingangs bezeichneten Art wird diese Aufgabe gemäß der Erfindung dadurch gelöst, daß der erfindungsgemäße Vorrichtungskörper von einem Profil ge¬ bildet wird mit in der Längsrichtung vorgesehenen Rast- nasenpaaren, die in der Montagelage die Abkröpfungen zweier benachbarter Randprofile der Kanalschüsse übergreifen und mit wenigstens einer das Durchstecken von Befestigungsmit¬ teln, wie Gewindestangen od. dgl., ermöglichenden Bohrung.With a device of the type described in the introduction, this object is achieved according to the invention in that the device body according to the invention is formed by a profile with latching means provided in the longitudinal direction. pairs of lugs, which in the assembly position overlap the offsets of two adjacent edge profiles of the channel sections and with at least one hole which enables fastening means, such as threaded rods or the like, to be pushed through.
Eine derart gestaltete Aufhängungsvorrichtung hat eine Fül¬ le von Vorteilen. So kann sie, wenn sie beispielsweise rechts und links auf obere Rahmenprofile der Kanalschüsse aufgesteckt wird, zur Aufhängung der Kanäle herangezogen werden. Wird sie auf seitliche Profile aufgesteckt, kann eine Wandmontage vorgesehen sein, das Aufstecken auf das untere Profil ermöglicht eine Bodenfixierung des Kanales.A suspension device designed in this way has a wealth of advantages. For example, if it is attached to the upper frame profiles of the channel sections on the right and left, it can be used to suspend the channels. If it is plugged onto side profiles, wall mounting can be provided; plugging onto the lower profile enables the duct to be fixed to the floor.
Ein weiterer Vorteil der erfindungsgemäßen Vorrichtung be¬ steht darin, daß durch diese Aufhängungs orrichtung zu¬ gleich Verspannfunktionen benachbarter Kanalschüsse über¬ nommen werden können, die ansonsten von zusätzlichen Mon¬ tageelementen, wie den schon erwähnten Spannklammern über¬ nommen werden muß.Another advantage of the device according to the invention is that this suspension device can at the same time take over bracing functions of adjacent channel sections, which would otherwise have to be taken over by additional mounting elements, such as the clamping clips already mentioned.
Weitere Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen.Further embodiments of the invention result from the subclaims.
So kann es zweckmäßig sein, insbesondere zur Verstärkung das Vorrichtungsprofil etwa C-förmig auszubilden. Auch kann der Mittelsteg des Profils mit einer Mehrzahl von die Rast- nasen bereitstellenden Ausprägungen versehen sein. Dabei sind zweckmäßig diese Ausprägungen in einem Bereich des Profiles, während der andere Bereich mit der Montageöffnung etwa zum Durchtritt von Gewindestangen versehen ist.Thus, it may be expedient to design the device profile approximately C-shaped, in particular for reinforcement. The central web of the profile can also be provided with a plurality of nose-providing features. These features are expedient in one area of the profile, while the other area is provided with the mounting opening, for example for the passage of threaded rods.
Um einen Anschlag bereitzustellen, der das Aufstecken der erfindungsgemäßen Vorrichtung nur so weit ermöglicht, daß die Befestigungsbohrung frei bleibt, d.h. das Kanalprofil nach außen weisend überragt, sieht die Erfindung auch vor, daß es etwa mittig zwischen der Durchtrittsbohrung und den die Rastnasen bereitstellenden Ausprägungen einer weiteren Ausprägung vorgesehen ist mit einer quer zur Profilrichtung verlaufenden Anschlagnase.In order to provide a stop which only allows the device according to the invention to be plugged on so far that the fastening bore remains free, i.e. Overhanging the channel profile facing outwards, the invention also provides that it is provided approximately in the middle between the through-bore and the forms of the further provision which provide the latching lugs, with a stop nose running transversely to the profile direction.
Die Erfindung ist nachstehend anhand der Zeichnung bei¬ spielsweise näher erläutert. Diese zeigt inThe invention is explained in more detail below with reference to the drawing, for example. This shows in
Fig. 1 eine vereinfachte räumliche Darstellung derFig. 1 shows a simplified spatial representation of the
Trennfugenebene zweier Kanalschüsse, ausgerü¬ stet mit einem Paar der erfindungsgemäßen Vor¬ richtung sowie in denParting plane of two channel sections, equipped with a pair of the device according to the invention and in the
Fig. 2 bis 4 Grundriß, Aufriß und Seitenriß eines erfin¬ dungsgemäßen profilierten Vorrichtungskörpers. Ein allgemein mit 1 bezeichneter Luftkanal wird von einer Vielzahl von mit 2 bezeichneten Kanalschüssen gebildet, die mit außenrandseitig aufgesetzten Randprofilen 3 ausgerüstet sind, die im nach außen weisenden oberen Profilbereich in Richtung auf den jeweiligen Kanalschuß weisende Abkröpfun¬ gen 3a aufweisen.2 to 4 plan, elevation and side elevation of a profiled device body according to the invention. An air duct generally denoted by 1 is formed by a multiplicity of duct sections denoted by 2, which are equipped with edge profiles 3 placed on the outer edge side and which have angled portions 3a in the outwardly pointing upper profile region in the direction of the respective duct section.
Die erfindungsgemäße, allgemein mit 4 bezeichnete Vorrich¬ tung besteht im wesentlichen aus einem Metallprofil, dessen Mittelsteg 5 eine Mehrzahl von unterschiedlichen Ausprägun¬ gen aufweist.The device according to the invention, generally designated 4, essentially consists of a metal profile, the central web 5 of which has a plurality of different configurations.
Wie sich insbesondere aus den Fig. 2 bis 4 ergibt, sind im dargestellten Beispiel im rechten Bereich der Vorrichtung 4 drei Paar von durch Ausstanzen und Umprägen erzeugte Rast¬ nasen 6 ausgebildet, die sich in der Montagelage unter die Abkröpfungen 3a der Randprofile 3 legen und damit die Vor¬ richtung 4 fixieren können.As can be seen in particular from FIGS. 2 to 4, three pairs of locking noses 6 produced by punching and embossing are formed in the example shown in the right-hand area of the device 4, which, in the installed position, lie under the bends 3a of the edge profiles 3 and so that the device 4 can fix.
Durch einfaches Aufschlagen der Vorrichtung 4 auf ein Paar von gegenüberliegenden Abkröpfungen 3a können die Randpro¬ file 3 gegeneinander verspannt und die Vorrichtung 4 an den Kanal 1 befestigt werden.The edge profiles 3 can be braced against one another and the device 4 can be fastened to the channel 1 by simply striking the device 4 on a pair of opposing bends 3a.
Zur Begrenzung der Aufschlagbewegung kann eine quer zur Mittelachse 7 des Steges 5 verlaufende weitere Ausprägung 8 vorgesehen sein, die durch die Ausprägung eine Anschlag¬ lasche 9 bereitstellt. Neben dieser Ausprägung 8 ist ein Ort zum Durchtritt, z.B. eine Gewindestange 10 strichpunk¬ tiert in Fig. 1 angedeutet, und eine Durchtrittsbohrung 11 vorgesehen.To limit the impact movement, a further characteristic 8 running transverse to the central axis 7 of the web 5 can be used be provided, which provides a stop tab 9 due to the configuration. In addition to this characteristic 8, a place for passage, for example a threaded rod 10 indicated by dash-dotted lines in FIG. 1, and a passage hole 11 are provided.
Zur Versteifung und Verstärkung der Vorrichtung 4 ist diese für sich gesehen zusätzlich querschnittlich C-förmig ausge¬ bildet, wie sich dies insbesondere aus Fig. 4 ergibt.For stiffening and reinforcing the device 4, the device 4 is also of a C-shaped cross section, as can be seen in particular in FIG. 4.
Natürlich ist das beschriebene Ausführungsbeispiel der Er¬ findung noch in vielfacher Hinsicht abzuändern, ohne den Grundgedanken zu verlassen. So ist die Erfindung insbeson¬ dere nicht auf die dargestellten drei Ausprägungen zur Be¬ reitstellung von Rastnasen 6 beschränkt, es kann eine wei¬ tere Anzahl vorgesehen sein. Auch andere Gestaltungen der für die Gewindestangen 10 vorgesehenen Bohrungen 11 können anders als dargestellt ausgebildet sein. Auch können die Rastnasen 6 unmittelbar von den Randbereichen des C-Profi- les bei entsprechend breiter Ausbildung des Mittelsteges gebildet sein. Zur Vereinfachung des Aufschiagens der Vor¬ richtung 4 kann auch der Einlaufbereich konisch erweitert sein, was durch eine gestrichelte Linie 12 in Fig. 2, rech¬ te Figurenhälfte, angedeutet ist. Of course, the described embodiment of the invention can be modified in many ways without departing from the basic idea. In particular, the invention is not limited to the three versions shown for the provision of locking lugs 6; a further number can be provided. Other configurations of the bores 11 provided for the threaded rods 10 can also be designed differently than shown. The locking lugs 6 can also be formed directly from the edge regions of the C-profile with a correspondingly wide design of the central web. To simplify the opening of the device 4, the inlet area can also be flared, which is indicated by a broken line 12 in FIG. 2, right half of the figure.
