Description

Die Erfindung betrifft eine Befestigungsvorrichtung, insbesondere eine Rasterdecke, für Reinräume nach dem Oberbegriff des Anspruches 1.The invention relates to a fastening device, in particular a grid ceiling, for clean rooms according to the preamble of claim 1.

Es ist bekannt, Filter-Ventilator-Einheiten mittels eines Einbaurahmens auf der Befestigungsvorrichtung zu montieren. Sie wird üblicherweise durch eine Rasterdecke gebildet, die aus Knotenpunkten und diese verbindenden Profilschienen gebildet wird. Der Einbaurahmen ist teuer in der Herstellung und führt zu einer aufwendigen Montage der Filter-Ventilator-Einheiten. An der Unterseite der Filter-Ventilator-Einheit wird ein Filter befestigt, das unmittelbar auf den Auflageschienen der Befestigungsvorrichtung aufliegt. Innerhalb eines Reinraumes ist der Einbau derjenigen Filter von der Reinraumseite aus nicht oder nur umständlich möglich, die im Bereich von Seitenwänden des Reinraumes in der entsprechenden Rasteröffnung montiert werden müssen. Die Rasteröffnung muß in diesem Fall rechteckigen Umriß haben, damit dieses Filter in der einen Lage von unten durch die Rasteröffnung gesteckt und in einer anderen Lage von oben auf die Auflageschienen aufgesetzt werden kann. Hat die Rasteröffnung quadratischen Umriß, kann das Filter nur von oben montiert werden. Dies ist aber nur möglich, wenn im Bereich oberhalb der Befestigungsvorrichtung ein entsprechender Freiraum vorhanden ist.It is known to mount filter-fan units on the fastening device by means of an installation frame. It is usually formed by a grid ceiling, which is formed from nodes and profile rails connecting them. The installation frame is expensive to manufacture and leads to complex assembly of the filter-fan units. A filter is attached to the underside of the filter-fan unit, which lies directly on the support rails of the fastening device. The installation of those filters from the clean room side, which have to be installed in the corresponding grid opening in the area of the side walls of the clean room, is not possible or only with great difficulty within a clean room. In this case, the grid opening must have a rectangular outline so that this Filters can be inserted through the grid opening in one position from below and placed on the support rails from above in another position. If the grid opening has a square outline, the filter can only be installed from above. However, this is only possible if there is a corresponding free space in the area above the fastening device.

Der Erfindung liegt die Aufgabe zugrunde, die gattungsgemäße Befestigungsvorrichtung so auszubilden, daß die Filter-Ventilator-Einheiten und das Filter vom Reinraum aus einfach montiert werden können, ohne daß im Bereich oberhalb der Befestigungsvorrichtung ein entsprechend hoher Freiraum vorhanden sein muß.The invention has for its object to design the generic fastening device so that the filter-fan units and the filter can be easily installed from the clean room without a correspondingly high clearance must be available in the area above the fastening device.

Diese Aufgabe wird bei der gattungsgemäßen Befestigungsvorrichtung erfindungsgemäß mit den kennzeichnenden Merkmalen des Anspruches 1 gelöst.This object is achieved in the generic fastening device according to the invention with the characterizing features of claim 1.

Bei der erfindungsgemäßen Befestigungsvorrichtung werden zur Abstützung der Filter-Ventilator-Einheiten auf den Auflageschienen die Auflageteile verwendet, die vorteilhaft leistenförmig ausgebildet sind. Die Filter-Ventilator-Einheit wird durch die Rasteröffnung vom Reinraum aus angehoben. Anschließend werden die Auflageteile auf die Auflageschienen aufgelegt. Die angehobene Filter-Ventilator-Einheit kann dann wieder abgesenkt werden, bis sie direkt oder indirekt auf den Auflageteilen abgestützt wird. Sie ragen in den Bereich der Rasteröffnung, so daß die Filter-Ventilator-Einheit sicher abgestützt wird. Bei der Montage muß die Filter-Ventilator-Einheit nur so weit durch die Rasteröffnung nach oben angehoben werden, daß die Auflageteile auf den Auflageschienen aufgelegt werden können. Dadurch wird im Bereich oberhalb der Befestigungsvorrichtung kein hoher Einbauraum benötigt. Seine Höhe muß nur wenig größer als die Höhe der Filter-Ventilator-Einheit und gegebenenfalls des darunter befindlichen Filters sein.In the fastening device according to the invention, the support parts, which are advantageously designed as strips, are used to support the filter-fan units on the support rails. The filter-fan unit is lifted from the clean room through the grid opening. Then the support parts are placed on the support rails. The raised filter-fan unit can then be lowered again until it is supported directly or indirectly on the support parts. They protrude into the area of the grid opening, so that the filter-fan unit is securely supported. During assembly, the filter-fan unit only has to be lifted up through the grid opening so that the support parts can be placed on the support rails. This will make the area above the mounting device does not require a large installation space. Its height only has to be slightly greater than the height of the filter-fan unit and, if applicable, of the filter underneath.

Weitere Merkmale der Erfindung ergeben sich aus den weiteren Ansprüchen, der Beschreibung und der Zeichnung.Further features of the invention result from the further claims, the description and the drawing.

Die Zeichnung zeigt einen Teil einer Reinraumdecke mit einer erfindungsgemäßen Befestigungsvorrichtung.The drawing shows part of a clean room ceiling with a fastening device according to the invention.

Die in der Zeichnung teilweise dargestellte Reinraumdecke hat eine rahmenförmige Deckenkonstruktion 1 mit senkrecht einander kreuzenden Profilschienen 2, die in bekannter Weise durch (nicht dargestellte) Knotenpunkte miteinander verbunden sind. Die Profilschienen 2 und die Knotenpunkte begrenzen rechteckförmige oder quadratische Einbauöffnungen 3 für Filter-Ventilator-Einheiten 4. Sie sind in noch zu beschreibender Weise auf der Deckenkonstruktion 1 aufgelagert. Da die Filter-Ventilator-Einheiten 4 an sich bekannt sind, werden sie nicht näher beschrieben. Unterhalb der Filter-Ventilator-Einheiten 4 befindet sich in bekannter Weise ein Filter 5, durch den die von der Einheit 4 angesaugte Reinluft vor dem Eintritt in den Reinraum 6 strömen muß. Die Filter 5 sind ebenfalls bekannt und werden darum nicht näher beschrieben.The clean room ceiling partially shown in the drawing has a frame-shaped ceiling construction 1 with perpendicularly crossing profile rails 2, which are connected to one another in a known manner by means of (not shown) nodes. The profile rails 2 and the nodes delimit rectangular or square installation openings 3 for filter-fan units 4. They are supported on the ceiling construction 1 in a manner to be described. Since the filter-fan units 4 are known per se, they are not described in detail. Below the filter-fan units 4 there is a filter 5 in a known manner, through which the clean air drawn in by the unit 4 must flow before entering the clean room 6. The filters 5 are also known and are therefore not described in detail.

Die Deckenkonstruktion 1 kann an der Decke des Reinraumes aufgehängt sein. Es ist aber auch möglich, die Deckenkonstruktion 1 auf dem Boden des Reinraumes 6 abzustützen. Bei der in der Zeichnung dargestellten Deckenkonstruktion 1 sind die Profilschienen 2 und/oder die Knotenpunkte mit aufwärts ragenden Profilteilen 7 versehen, an denen in bekannter Weise (nicht dargestellte) Seile, Drähte und dergleichen zum Abhängen der Deckenkonstruktion 1 an der Decke des Reinraumes 6 befestigt werden können. Die Profilteile 7 sind vorteilhaft einstückig mit den Profilschienen 2 und/oder den Knotenpunkten ausgebildet.The ceiling structure 1 can be suspended from the ceiling of the clean room. But it is also possible to support the ceiling structure 1 on the floor of the clean room 6. In the ceiling construction 1 shown in the drawing, the profile rails 2 and / or the nodes are provided with upwardly projecting profile parts 7, on which ropes, wires and the like (not shown) for hanging the ceiling structure 1 can be attached to the ceiling of the clean room 6 in a known manner. The profile parts 7 are advantageously formed in one piece with the profile rails 2 and / or the nodes.

Die Profilschienen 2 haben jeweils zwei auf gleicher Höhe liegende Auflageschenkel 8, 9, durch welche die jeweilige Einbauöffnung 3 begrenzt wird. Auf den in der Einbaulage horizontalen Auflageschenkeln 8, 9 wird jeweils eine Auflageleiste 10, 11 aufgesetzt. Sie ragt über den jeweiligen Auflageschenkel 8, 9 in die Einbauöffnung 3. An einem Längsrand hat die Auflageleiste 10, 11 einen aufwärts gerichteten Rand 12, der in der Einbaulage an der Unterseite eines Widerlagers 13 der jeweiligen Profilschiene 2 anliegt. Die Widerlager 13 liegen mit Abstand oberhalb der Auflageschenkel 8, 9 und verlaufen parallel zu ihnen. Da sie lediglich zur Abstützung der Auflageleisten 10, 11 dienen, sind sie quer zur Längsrichtung der Profilschiene 2 kürzer als die Auflageschenkel 8, 9. Der freie Rand 14 der Widerlager 13 ist in Richtung auf die Auflageschenkel 8, 9 abgewinkelt und bildet eine Sicherung für die jeweilige Auflageleiste 10, 11. Durch den abgewinkelten Rand 14 wird verhindert, daß die Auflageleiste 10, 11 quer zu ihrer Längsrichtung unbeabsichtigt vom Widerlager 13 freikommt.The profile rails 2 each have two support legs 8, 9 lying at the same height, through which the respective installation opening 3 is limited. A support bar 10, 11 is placed on each of the horizontal support legs 8, 9 in the installed position. It protrudes over the respective support leg 8, 9 into the installation opening 3. On a longitudinal edge, the support strip 10, 11 has an upwardly directed edge 12 which, in the installed position, rests on the underside of an abutment 13 of the respective profile rail 2. The abutments 13 are spaced above the support legs 8, 9 and run parallel to them. Since they only serve to support the support strips 10, 11, they are shorter transversely to the longitudinal direction of the profile rail 2 than the support legs 8, 9. The free edge 14 of the abutment 13 is angled in the direction of the support legs 8, 9 and forms a backup for the respective support bar 10, 11. The angled edge 14 prevents the support bar 10, 11 from being unintentionally released from the abutment 13 transversely to its longitudinal direction.

Die Auflageleiste 10, 11 weist mit Abstand vom Rand 12 einen parallel zu ihm verlaufenden Steg 15 auf, der zur Zentrierung des Filters 5 in der Einbaulage dient. Der Steg 15 kann gleiche Höhe wie der freie Rand 12 der Auflageleiste 10, 11 haben. In der Einbaulage liegt der Steg 15 etwa in Höhe des freien Randes der Auflageleiste 8, 9.The support bar 10, 11 has, at a distance from the edge 12, a web 15 running parallel to it, which serves to center the filter 5 in the installed position. The web 15 can have the same height as the free edge 12 of the support bar 10, 11. In the installation position Web 15 approximately at the level of the free edge of the support bar 8, 9.

Der Filter 5 liegt mit einem ihn umgebenden Rahmen 16 auf der jeweiligen Auflageleiste 10, 11 auf. Die Querschnittsfläche des Filters 5 ist kleiner als die Querschnittsfläche der jeweiligen Einbauöffnung 3. Da die Auflageleisten 10, 11 jedoch über die Auflageschenkel 8, 9 in den freien Querschnitt der Einbauöffnung 3 ragen, wird der Filter 5 zuverlässig auf den Auflageleisten 10, 11 abgestützt. Die Stege 15 der Auflageleisten 10, 11 dienen zur Zentrierung des jeweiligen Filters 5 in der Einbauöffnung 3. Auch die Filter-Ventilator-Einheiten 4 haben eine kleinere Querschnittsfläche als die jeweilige Einbauöffnung 3. Die Filter-Ventilator-Einheiten 4 werden über die Filter 5 auf den Auflageleisten 10, 11 abgestützt. Da sich die Auflageleisten 10, 11 mit ihren aufwärts gerichteten freien Rändern 12 an der Unterseite der Widerlager 13 der Profilschienen 2 abstützen, können die Auflageleisten 10, 11 unter dem Gewicht der Filter 5 und der Filter-Ventilator-Einheiten 4 nicht kippen. Dadurch sind die Einheiten 4 und die Filter 5 in der Einbaulage einwandfrei lagegesichert. Darüber hinaus verhindern die nach unten gerichteten freien Ränder 14 der Widerlager 13, daß die Auflageleisten 10, 11 quer zu den Profilschienen 2 verschoben werden können.The filter 5 lies with a frame 16 surrounding it on the respective support bar 10, 11. The cross-sectional area of the filter 5 is smaller than the cross-sectional area of the respective installation opening 3. However, since the support strips 10, 11 project beyond the support legs 8, 9 into the free cross-section of the installation opening 3, the filter 5 is reliably supported on the support strips 10, 11. The webs 15 of the support strips 10, 11 serve to center the respective filter 5 in the installation opening 3. The filter-fan units 4 also have a smaller cross-sectional area than the respective installation opening 3. The filter-fan units 4 are moved over the filters 5 supported on the support strips 10, 11. Since the support strips 10, 11 are supported with their upward free edges 12 on the underside of the abutments 13 of the profile rails 2, the support strips 10, 11 cannot tilt under the weight of the filters 5 and the filter-fan units 4. As a result, the units 4 and the filters 5 are properly secured in the installed position. In addition, the downward free edges 14 of the abutment 13 prevent the support strips 10, 11 can be moved transversely to the profile rails 2.

Die Auflageleisten 10, 11 erstrecken sich zumindest über einen Teil der Länge der jeweiligen Profilschiene 2. Es reicht zur Auflagerung der Filter-Ventilator-Einheiten 4 und der Filter 5 aus, wenn sich die Auflageleisten 10, 11 nur über einen Teil der Länge der Profilschienen 2 erstrecken. Vorteilhaft sind an allen vier Rändern der Einbauöffnung 3 derartige Auflageleisten vorgesehen, so daß eine optimale Abstützung der Filter-Ventilator-Einheiten 4 mit den Filtern 5 gewährleistet ist. Grundsätzlich reicht es aus, lediglich an zwei einander gegenüberliegenden Rändern der Einbauöffnung 3 entsprechende Auflageleisten 10, 11 vorzusehen. Um ein Kippen der Einheiten zu vermeiden, sind in diesem Falle die Auflageleisten 10, 11 entsprechend lang ausgebildet.The support strips 10, 11 extend at least over part of the length of the respective profile rail 2. It is sufficient to support the filter-fan units 4 and the filter 5 if the support strips 10, 11 extend only over part of the length of the profile rails 2 extend. Such support strips are advantageously provided on all four edges of the installation opening, so that an optimal support of the filter-fan units 4 with the filters 5 is guaranteed. Basically, it is sufficient to provide corresponding support strips 10, 11 only on two opposite edges of the installation opening 3. In order to prevent the units from tipping over, in this case the support strips 10, 11 are designed to be correspondingly long.

Die Auflageleisten 10, 11 können auch als Winkelstücke ausgebildet sein, die in den Eckbereichen der Einbauöffnung 3 angeordnet sind. In diesem Falle erfolgt die Abstützung der Einheiten 4 mit den Filtern 5 in den Ecken der jeweiligen Einbauöffnung 3. Es ist auch möglich, derartige winkelförmige Auflageleisten 10, 11 zusammen mit entsprechend länglichen Auflageleisten zu verwenden.The support strips 10, 11 can also be designed as angle pieces which are arranged in the corner regions of the installation opening 3. In this case, the units 4 are supported with the filters 5 in the corners of the respective installation opening 3. It is also possible to use such angular support strips 10, 11 together with correspondingly elongate support strips.

Bei der Montage der Reinraumdecke wird zunächst die Deckenkonstruktion 1 montiert, die eine Rasterdecke mit den entsprechenden Einbauöffnungen 3 bildet. Anschließend können die Filter-Ventilator-Einheiten 4 mit den Filtern 5 vom Reinraum 6 aus montiert werden, indem sie durch die Einbauöffnungen 3 nach oben gehoben werden. Anschließend werden die Auflageleisten 10, 11 auf die Auflageschenkel 8, 9 der Profilschienen 2 so aufgelegt, daß ihre aufwärts gerichteten Ränder 12 in der in der Zeichnung dargestellten Weise an der Unterseite der Widerlager 13 der Profilschienen 2 anliegen. Die nach unten gerichteten freien Ränder 14 der Widerlager 13 sind verhältnismäßig kurz, so daß die Auflageleisten 10, 11 durch eine geringe Schrägstellung leicht in ihre Einbaulage gebracht werden können. Anschließend werden die Einheiten 4 und die Filter 5 abgesenkt, bis die Filter 5 mit ihrem Rahmen 16 auf den über die Auflageschenkel 8, 9 ragenden Teilen der Auflageleisten 10, 11 aufsitzen.When installing the clean room ceiling, the ceiling structure 1 is first installed, which forms a grid ceiling with the corresponding installation openings 3. The filter-fan units 4 with the filters 5 can then be installed from the clean room 6 by lifting them up through the installation openings 3. Then the support strips 10, 11 are placed on the support legs 8, 9 of the profile rails 2 so that their upward edges 12 rest in the manner shown in the drawing on the underside of the abutment 13 of the profile rails 2. The downward free edges 14 of the abutment 13 are relatively short, so that the support strips 10, 11 can be easily brought into their installation position by a slight inclination. The units 4 and the filters 5 are then lowered until the filter 5 with its frame 16 is seated on the parts of the support strips 10, 11 projecting over the support legs 8, 9.

Auf diese Weise lassen sich in sämtlichen Einbau- bzw. Rasteröffnungen 3 die jeweiligen Einheiten 4 und Filter 5 von unten montieren. Die Stege 15, die sich über die ganze Länge oder nur über einen Teil der Länge der Auflageleisten 10, 11 erstrecken können, dienen zur Zentrierung der Einheiten 4 und der Filter 5, so daß eine einfache und schnelle Montage der Reinraumdecke gewährleistet ist. Eine Verschraubung, Verklebung oder sonstige Verbindung der Auflageleisten 10, 11 mit den Profilschienen 2 ist nicht erforderlich, so daß die Auflageleisten 10, 11 im Bedarfsfall einfach ausgetauscht werden können. Auch ist dadurch eine einfache Demontage der Reinraumdecke möglich.In this way, the respective units 4 and filters 5 can be mounted from below in all installation or grid openings 3. The webs 15, which can extend over the entire length or only over part of the length of the support strips 10, 11, serve to center the units 4 and the filter 5, so that a simple and quick assembly of the clean room ceiling is ensured. A screwing, gluing or other connection of the support strips 10, 11 with the profile rails 2 is not necessary, so that the support strips 10, 11 can be easily replaced if necessary. This also makes it easy to remove the clean room ceiling.

Der Rahmen 16 für die Filter 5 weist bei den beiden in der Zeichnung linken Filtern 5 am oberen Rand eine Profilaufnahme 17 für eine Dichtung 18 auf. Auf ihr sitzt die Einheit 4 auf. Der Rahmen 16 sitzt mit seinem unteren Rand unmittelbar auf den Auflageleisten 10, 11 auf.The frame 16 for the filter 5 has in the two filters 5 on the left in the drawing a profile receptacle 17 for a seal 18. Unit 4 sits on it. The frame 16 sits with its lower edge directly on the support strips 10, 11.

Bei den beiden in der Zeichnung rechten Filtern 5 hat der Rahmen 16 auch am unteren Rand eine Profilaufnahme 19 für eine Dichtung 20. Mit ihr liegt der Filter 5 auf der Auflageleiste 10, 11 auf.In the case of the two filters 5 on the right in the drawing, the frame 16 also has a profile receptacle 19 for a seal 20 at the lower edge. With it, the filter 5 rests on the support strip 10, 11.

An den Auflageleisten 10, 11 kann beispielsweise eine Abdeckung 22 befestigt werden, die die Deckenkonstruktion gegen den Reinraum 6 abdeckt. Wie in der Zeichnung beispielhaft dargestellt ist, sind an der Unterseite der Auflageleisten 11 nach unten ragende Abstandhalter 23 befestigt, die hülsenförmig ausgebildet sind und eine durchgehende Gewindebohrung 24 aufweisen. Die Abstandhalter 23 sind über die Deckenkonstruktion 1 verteilt angeordnet. Die Auflageleisten 11 sind im Bereich außerhalb der Profilschienen 2 mit Durchgangsöffnungen für Gewindebolzen 25 versehen, die von oben in die Gewindebohrung 24 des entsprechenden Abstandhalters 23 geschraubt werden. Der Kopf der Gewindebolzen 25 liegt vorteilhaft versenkt in den Auflageleisten 11, so daß die Rahmen 16 der Filter 5 ohne Behinderung durch die Gewindebolzen 25 aufgesetzt werden können. Mit den Gewindebolzen 25 werden die Abstandshalter 23 fest gegen die Unterseite der Auflageleisten 11 gezogen. In die Gewindebohrungen 24 der Abstandhalter 23 werden von unten weitere Gewindebolzen 26 geschraubt, mit denen an der Unterseite der Abstandhalter 23 die Abdeckung 22 befestigt wird. Sie wird vorteilhaft durch Lochbleche gebildet, die einen umlaufenden, aufwärts gerichteten Rand 27 aufweisen. Die Abstandhalter 23 liegen nahe benachbart zum Rand 27 innerhalb des jeweiligen Lochbleches 22. Im Bereich der Gewindebolzen 26 ist die Gewindebohrung 24 der Abstandhalter 23 in geeigneter Weise abgedichtet.For example, a cover 22 can be attached to the support strips 10, 11, which covers the ceiling construction against the clean room 6. As is shown by way of example in the drawing, spacers 23 projecting downward are attached to the underside of the support strips 11, which are sleeve-shaped and have a continuous threaded bore 24. The spacers 23 are arranged distributed over the ceiling structure 1. The support strips 11 are in the area outside of the profile rails 2 are provided with through openings for threaded bolts 25 which are screwed into the threaded bore 24 of the corresponding spacer 23 from above. The head of the threaded bolt 25 is advantageously recessed in the support strips 11, so that the frame 16 of the filter 5 can be placed without hindrance by the threaded bolt 25. The spacers 23 are pulled firmly against the underside of the support strips 11 with the threaded bolts 25. Further threaded bolts 26 are screwed into the threaded bores 24 of the spacers 23, with which the cover 22 is fastened to the underside of the spacers 23. It is advantageously formed by perforated plates which have a circumferential, upwardly directed edge 27. The spacers 23 are located close to the edge 27 within the respective perforated plate 22. In the area of the threaded bolts 26, the threaded bore 24 of the spacers 23 is sealed in a suitable manner.

Die von den Filter-Ventilator-Einheiten 4 angesaugte Luft strömt durch die Filter 5 nach unten in den Reinraum 6, wobei sie durch die Öffnungen der Lochbleche 22 in den Reinraum 6 eintritt. Die Lochbleche 22 können einfach mit den Gewindebolzen 26 montiert und bei Bedarf auch demontiert werden.The air sucked in by the filter-fan units 4 flows down through the filters 5 into the clean room 6, whereby it enters the clean room 6 through the openings in the perforated plates 22. The perforated plates 22 can be easily assembled with the threaded bolts 26 and also disassembled if necessary.

Mit der beschriebenen Rasterdeckenkonstruktion 1 können die Filter-Ventilator-Einheiten 4 mit den Filtern 5 vom Reinraum 6 aus montiert werden. Die Auflageleisten 10, 11 gewährleisten hierbei, daß in sämtliche Rasteröffnungen 3 die Filter-Ventilator-Einheiten von unten montiert werden können. Die Auflageleisten 10, 11 stellen einfache, kostengünstig herstellbare Bauteile dar, so daß die Errichtung der Reinraumdecke einfach und kostengünstig durchgeführt werden kann. Die einzelnen Filter-Ventilator-Einheiten 4 können unabhängig voneinander demontiert werden. Bei der Montage und Demontage müssen die Filter-Ventilator-Einheiten 4 mit den Filtern 5 nur so weit angehoben werden, daß die flachen Auflageleisten 10, 11 in der beschriebenen Weise in die Profilschienen 2 eingehängt bzw. ausgehängt werden können. Darum ist im Bereich oberhalb der Rasterdeckenkonstruktion 1 nur eine geringe Bauhöhe erforderlich.With the grid ceiling construction 1 described, the filter-fan units 4 with the filters 5 can be installed from the clean room 6. The support strips 10, 11 ensure that the filter-fan units can be installed from below in all grid openings 3. The support strips 10, 11 represent simple, inexpensive to manufacture components, so that the erection of the clean room ceiling is simple and inexpensive can be carried out. The individual filter-fan units 4 can be disassembled independently of one another. During assembly and disassembly, the filter-fan units 4 with the filters 5 only have to be raised to such an extent that the flat support strips 10, 11 can be hung or unhooked in the profiled rails 2 in the manner described. Therefore, only a small overall height is required in the area above the grid ceiling construction 1.
