Description

Die Erfindung betrifft zunächst ein Bauwerk gemäß Anspruch 1 mit mindestens einer Druckschleuse zum Austauschen von Material und Personen zwischen dem Bauwerk und einem Sauberkeitsbereich in dem Bauwerk, einer Belüftungseinrichtung zum Zuführen von Zuluft aus dem Bauwerk oben in den Sauberkeitsbereich und einer Entlüftungseinrichtung zum Abführen von Abluft unten aus dem Sauberkeitsbereich in das Bauwerk derart, dass der Sauberkeitsbereich gegenüber dem Bauwerk einen Überdruck aufweist, wobei der Sauberkeitsbereich einen Boden und eine den Sauberkeitsbereich oberhalb des Bodens druckdicht umschließende Hülle und das Bauwerk eine Außenhülle aufweist, die den Sauberkeitsbereich vor einer Witterung außerhalb des Bauwerks schützt, und die Hülle mindestens überwiegend derart flexibel ist, dass der Sauberkeitsbereich erst durch den Überdruck eine Form erhält und der Überdruck die Hülle in der Form des Sauberkeitsbereichs hält. Die Erfindung betrifft weiterhin ein Verfahren gemäß Anspruch 10 zum Herstellen eines solchen Sauberkeitsbereichs.The invention relates first to a structure according to claim 1 with at least one pressure lock for exchanging material and people between the structure and a clean area in the structure, a ventilation device for supplying supply air from the structure at the top into the clean area, and a ventilation device for discharging exhaust air at the bottom from the clean area into the structure in such a way that the clean area has an overpressure relative to the structure, the clean area having a floor and an envelope pressure-tightly enclosing the clean area above the floor and the structure having an outer envelope which protects the clean area from weather outside the structure , and the shell is at least predominantly so flexible that the cleanliness area is only given a shape by the overpressure and the overpressure keeps the shell in the shape of the cleanliness area. The invention further relates to a method according to claim 10 for producing such a cleanliness area.

Solche Sauberkeitsbereiche sind aus WO 2013/127979 A1 und DE 32 35 927 C1 bekannt als sog. "Reinräume" (oder "Reinsträume"), denen gereinigte Luft von außen mit Überdruck zugeführt wird, um eine Kontamination mit in der Atmosphäre vorliegenden Partikeln und Keimen zu vermeiden. In solchen Sauberkeitsbereichen werden häufig im Bau und Betrieb regelmäßige Partikelmessungen durchgeführt, die eine Klassifizierung, insbesondere nach ISO 14644 ermöglichen. Die Druckschleuse vermeidet übermäßigen Druckverlust beim Zu- oder Abgang von Material und Personen zwischen dem Sauberkeitsbereich und seiner Umgebung im Bauwerk. Bei der baulichen Auslegung von Reinräumen und insbesondere bei einem Umbau eines vorhandenen Raums in einen Reinraum sind die durch den Überdruck entstehenden Flächenlasten auf Boden und Hülle, also Wände und Decke zu beachten.Such cleanliness areas are out WO 2013/127979 A1 and DE 32 35 927 C1 known as so-called "clean rooms" (or "clean rooms"), to which cleaned air is supplied from the outside at overpressure in order to avoid contamination with particles and germs present in the atmosphere. In such clean areas, regular particle measurements are often carried out during construction and operation, which enable classification, in particular according to ISO 14644. The pressure lock avoids excessive pressure loss when material and people enter or leave between the clean area and its surroundings in the structure. In the structural design of clean rooms and in particular when converting an existing room into a clean room, the surface loads on the floor and shell, i.e. walls and ceiling, caused by the overpressure must be taken into account.

Aufgabetask

Der Erfindung liegt die Aufgabe zugrunde, die Herstellung eines Sauberkeitsbereichs zu vereinfachen.The object of the invention is to simplify the production of a cleanliness area.

Lösungsolution

Ausgehend von den bekannten Bauwerken wird nach der Erfindung vorgeschlagen, dass die Hülle mindestens überwiegend derart flexibel ist, dass der Sauberkeitsbereich erst durch den Überdruck eine Form erhält und der Überdruck die Hülle in der Form des Sauberkeitsbereichs hält. Ein solcher Sauberkeitsbereich kann innerhalb eines Gebäudes "freitragend" hergestellt werden, ohne dass im Betrieb der Überdruck zusätzliche Flächenlasten auf Boden, Wände und Decken des Gebäudes ausübt.Proceeding from the known structures, it is proposed according to the invention that the envelope is at least predominantly flexible enough that the clean area only obtains a shape through the overpressure and the overpressure keeps the envelope in the shape of the clean area. Such a clean area can be created "self-supporting" within a building without the overpressure exerting additional surface loads on the floor, walls and ceilings of the building during operation.

Vorzugsweise führt in dem Sauberkeitsbereich die Entlüftungseinrichtung Abluft aus dem Innenraum durch einen Hohlraum in mindestens einer von dem Sauberkeitsbereich umschlossenen Säule in die Umgebung des Sauberkeitsbereichs ab. Reinräume werden üblicher Weise in Bodennähe, insbesondere durch an den Außenwänden angebrachte Entlüftungsklappen entlüftet. Darüber hinaus ist es bekannt, große Reinräume zusätzlich über im Sauberkeitsbereich angeordnete Säulen zu entlüften. In einem erfindungsgemäßen Sauberkeitsbereich bietet vorzugsweise eine im Sauberkeitsbereich angeordnete Säule darüber hinaus die Möglichkeit, die flexible Decke außer an den Wänden an einem zusätzlichen Punkt am Boden zu verankern und damit die lichte Höhe des Sauberkeitsbereichs zu begrenzen.In the clean area, the ventilation device preferably discharges exhaust air from the interior through a cavity in at least one column enclosed by the clean area into the environment of the clean area. Clean rooms are usually vented near the floor, in particular through ventilation flaps attached to the outer walls. In addition, it is known that large clean rooms can also be ventilated via columns arranged in the clean area. In a cleanliness area according to the invention, a column arranged in the cleanliness area preferably also offers the possibility of anchoring the flexible ceiling at an additional point on the floor in addition to the walls, and thus limiting the clear height of the cleanliness area.

Vorzugsweise weist der Sauberkeitsbereich eine Halterungsvorrichtung zum Haltern einer Beleuchtungseinrichtung in dem Sauberkeitsbereich auf. An einer solchen, typischer Weise über Kopfhöhe anordneten Halterungsvorrichtung können neben der Beleuchtungseinrichtung auch Luftauslässe der Belüftungseinrichtung angebracht werden.The cleanliness area preferably has a holding device for holding a lighting device in the cleanliness area. In addition to the lighting device, air outlets of the ventilation device can also be attached to such a mounting device, which is typically arranged above head height.

Vorzugsweise ist in dem Sauberkeitsbereich die Hülle mindestens abschnittsweise transparent. Ein solcher Sauberkeitsbereich ermöglicht den darin arbeitenden Personen durch die transparenten Abschnitte der Hülle hindurch eine optische Verbindung in das Gebäude außerhalb des Sauberkeitsbereichs. Alternativ oder zusätzlich können nicht-transparente Abschnitte der Hülle als Projektionsfläche beispielsweise zur indirekten Beleuchtung und grafischen Gestaltung des Sauberkeitsbereichs, für bedarfsweise wechselnde technische Informationen oder auch für bewegte Bilder, beispielsweise für die Übertragung einer Videokonferenz genutzt werden.In the cleanliness area, the casing is preferably transparent at least in sections. Such a clean area enables the people working in it to have an optical connection to the building outside the clean area through the transparent sections of the shell. Alternatively or additionally, non-transparent sections of the cover can be used as a projection surface, for example for indirect lighting and graphic design of the cleanliness area, for technical information that changes as required, or also for moving images, for example for the transmission of a video conference.

Vorzugsweise weist in dem Sauberkeitsbereich die Hülle mindestens abschnittsweise ein Gewebe auf. Die Verstärkung der Hülle mit einem Gewebe vermeidet eine unerwünschte Dehnung der Hülle durch den Überdruck.In the cleanliness area, the casing preferably has a fabric at least in sections. The reinforcement of the cover with a fabric avoids an undesired stretching of the cover by the overpressure.

Vorzugsweise weist der Sauberkeitsbereich einen symmetrischen, insbesondere einen punktsymmetrischen Grundriss auf. Die Belüftungseinrichtung kann dann einfach so gestaltet werden, dass der Sauberkeitsbereich homogene Strömungsverhältnisse aufweist.The cleanliness area preferably has a symmetrical, in particular a point-symmetrical, outline. The aeration device can then simply be designed in such a way that the clean area has homogeneous flow conditions.

Vorzugsweise weist der Sauberkeitsbereich eine im Wesentlichen vertikale seitliche Wand auf. Der Sauberkeitsbereich beansprucht dann über seine begehbare Nutzfläche hinaus keinen weiteren Stellplatz.Preferably, the cleanliness area has a substantially vertical side wall. The cleanliness area then does not take up any further parking space beyond its usable area.

Vorzugsweise weist der Sauberkeitsbereich eine gewölbte Decke auf. Eine gewölbte Raumdecke vermittelt den optischen Eindruck eines hohen Raums.The cleanliness area preferably has a vaulted ceiling. A vaulted ceiling gives the visual impression of a high room.

Vorzugsweise ist der Sauberkeitsbereich ein Reinraum. Ein Reinraum ist ein nach EN ISO 14644 zertifizierter Sauberkeitsbereich. Alternativ kann ein erfindungsgemäßer Sauberkeitsbereich eine niedrigere Sauberkeitsstufe nach VDA 19 Teil 2 aufweisen, und insbesondere als nicht regulierter Sauberkeitsbereich (SaS0), als Sauberzone (SaS1) oder als Sauberraum (SaS2) genutzt werden.The clean area is preferably a clean room. A clean room is a cleanliness area certified according to EN ISO 14644. Alternatively, a cleanliness area according to the invention can have a lower level of cleanliness VDA 19 Part 2, and used in particular as a non-regulated clean area (SaS0), as a clean zone (SaS1) or as a clean room (SaS2).

Ausgehend von den bekannten Verfahren wird nach der Erfindung vorgeschlagen, dass die Hülle mindestens überwiegend derart flexibel ist, dass sie durch den Überdruck die Form des Sauberkeitsbereichs erhält, der durch Zuführen der Zuluft mittels der Belüftungseinrichtung entsteht. Das erfindungsgemäße Verfahren führt zu einem der vorstehend beschriebenen Sauberkeitsbereiche und zeichnet sich gleichermaßen durch die dort aufgeführten Vorteile aus.Proceeding from the known methods, it is proposed according to the invention that the shell is at least predominantly flexible enough that the excess pressure gives it the shape of the clean area that is created by supplying the supply air by means of the ventilation device. The method according to the invention leads to one of the cleanliness areas described above and is equally distinguished by the advantages listed there.

Der in den Figuren gezeigte erfindungsgemäß hergestellte Sauberkeitsbereich 1 weist einen kreisförmigen, im Wesentlichen punktsymmetrischen Grundriss 2 mit einem Durchmesser 3 von 13 m und einer begehbaren Nutzfläche 4 von 130 m2 auf. Eine auf dem Boden 5 verankerte flexible Hülle 6 bildet eine im Wesentlichen senkrechte seitliche Wand 7 und eine torusförmig gewölbte Decke 8 sowie in der Mitte 9 des Sauberkeitsbereichs 1 eine Säule 10 mit einem Durchmesser 11 von 80 cm. The cleanliness area 1 produced according to the invention shown in the figures has a circular, essentially point-symmetrical floor plan 2 with a diameter 3 of 13 m and a usable area 4 of 130 m 2 that can be walked on. A flexible cover 6 anchored to the floor 5 forms a substantially vertical lateral wall 7 and a toroidal curved ceiling 8 and in the center 9 of the cleanliness area 1 a column 10 with a diameter 11 of 80 cm.

Die Hülle 6 besteht im Wesentlichen aus einem Polyurethan-beschichteten Gewebe, das im Bereich der Wand 7 großflächig von einer klaren PVC-Folie mit einer Dicke von 0,5 mm unterbrochen ist. Einzelne Felder der Hülle 6 sind durch Reißverschlüsse verbunden, um Lagerung, Transport, Auf- und Abbau der Hülle 6 zu vereinfachen. (Die Folie, die Felder und Reisverschlüsse sind nicht dargestellt.) Der Sauberkeitsbereich 1 weist zwei einander gegenüber angeordnete Druckschleusen 12 für Personen - beispielsweise getrennt für Frauen und Männer - sowie eine zwischen diesen angeordnete Druckschleuse 13 für Material auf. Die Druckschleusen 12, 13 weisen jeweils eine Außentür 14 und eine Fluchttür 15 nach außen sowie eine Innentür 16 zum Sauberkeitsbereich 1 auf. Zwischen der Außentür 14 und der Innentür 16 befindet sich eine Sitzbank 17, auf der Personen bei Betreten des Sauberkeitsbereichs 1 Straßenkleidung gegen reinraumgerechte Kleidung wechseln oder entsprechende Schutzkleidung überziehen und umgekehrt beim Verlassen des Sauberkeitsbereichs 1 ablegen können. Die Druckschleusen 12, 13 weisen eine nicht dargestellte Tragkonstruktion aus Stahlprofilen auf.The shell 6 essentially consists of a polyurethane-coated fabric, which is interrupted over a large area in the area of the wall 7 by a clear PVC film with a thickness of 0.5 mm. Individual panels of the cover 6 are connected by zippers in order to simplify storage, transport, assembly and dismantling of the cover 6. (The foil, panels and zippers are not shown.) The cleanliness area 1 has two pressure locks 12 arranged opposite one another for people—for example, separately for women and men—and a pressure lock 13 for material arranged between them. The pressure locks 12, 13 each have an outer door 14 and an escape door 15 to the outside and an inner door 16 to the cleanliness area 1. Between the outer door 14 and the inner door 16 there is a bench 17 on which people can change street clothes for cleanroom-appropriate clothing when entering the cleanroom area 1 or put on appropriate protective clothing and vice versa when they leave the cleanroom area 1. The pressure locks 12, 13 have a support structure, not shown, made of steel profiles.

Unter der Decke 8 des Sauberkeitsbereichs 1 ist über Kopfhöhe eine Tragvorrichtung 18 angeordnet. Die Tragvorrichtung 18 hängt an nicht dargestellten, durch die Decke 8 des Sauberkeitsbereichs 1 geführten Ketten, die außerhalb des Sauberkeitsbereichs 1 an einer in der Säule 10 stehenden Stützspinne 19 aufgehängt sind. An der Tragvorrichtung 18 sind nicht dargestellte Beleuchtungselemente zum Beleuchten des Sauberkeitsbereichs 1 angebracht.A support device 18 is arranged above head height under the ceiling 8 of the cleanliness area 1 . The carrying device 18 hangs on chains, not shown, which are guided through the ceiling 8 of the cleanliness area 1 and are suspended outside of the cleanliness area 1 on a support spider 19 standing in the column 10 . Lighting elements (not shown) for illuminating the cleanliness area 1 are attached to the support device 18 .

Der Sauberkeitsbereich 1 befindet sich im Innern eines Bauwerks 20. Das Bauwerk 20 ist eine Gewerbehalle mit einer Außenhülle 21 aus standardisierten Leichtbau-Fertigteilen mit einer Tragkonstruktion aus geschweißten Stahlprofilen. Die Fertigteile und die Tragkonstruktion sind nicht dargestellt.The clean area 1 is located inside a building 20. The building 20 is a commercial building with an outer shell 21 made of standardized lightweight prefabricated parts with a supporting structure made of welded steel profiles. The finished parts and the supporting structure are not shown.

Die Belüftungseinrichtung 22 des Sauberkeitsbereichs 1 weist ein neben dem Sauberkeitsbereich 1 aufgestelltes Lüftungsgerät 23, auf, das Umgebungsluft aus dem Innern des Bauwerks 20 ansaugt, über mehrere Filterstufen filtert und derart gereinigt über einen flexiblen Zuluftschlauch 24 mit 20 Pa Überdruck und 200 m3 /min in den Sauberkeitsbereich 1 einbläst. Der Zuluftschlauch 24 mündet in einen flexiblen Filterschlauch 25 mit einem durchströmten Querschnitt von 3300 cm2, der ringförmig mit einem Durchmesser 26 von 7 m gleichfalls in der Tragvorrichtung 18 unter der Decke 8 des Sauberkeitsbereichs 1 geführt ist.The ventilation device 22 of the cleanliness area 1 has a ventilation device 23 set up next to the cleanliness area 1, which sucks in ambient air from the interior of the building 20, filters it through several filter stages and cleans it in this way via a flexible air supply hose 24 with 20 Pa overpressure and 200 m 3 / min blows into cleanliness area 1. The supply air hose 24 ends in a flexible filter hose 25 with a flow cross section of 3300 cm 2 , which is also guided in a ring shape with a diameter 26 of 7 m in the support device 18 under the ceiling 8 of the cleanliness area 1 .

Die Entlüftungseinrichtung des Sauberkeitsbereichs 1 besteht einerseits aus je zwei gewichtsbelasteten Abluftklappen 27 in beiden seitlichen Wänden 28 der Druckschleusen 12, 13 und andererseits einem zu einer Tonne 29 gebogenen Gitterblech, das am Fuß 30 der Säule 10 auf dem Boden 5 steht. Die Abluftklappen 27 geben den Abluftstrom mit einer Druckdifferenz von jeweils 10 Pa zunächst aus dem Sauberkeitsbereich 1 in die Druckschleusen 12, 13 und aus diesen in die Umgebung des Sauberkeitsbereichs 1 im Bauwerk 20 frei. Die Säule 10 nimmt einen Abluftstrom von ca. 80 m3 /min und jede der Abluftklappen 27 einen Abluftstrom von ca. 20 m3 /min auf.The ventilation system of the cleanliness area 1 consists on the one hand of two weight-loaded exhaust air flaps 27 in both side walls 28 of the pressure locks 12, 13 and on the other hand of a grid plate bent into a barrel 29, which stands at the foot 30 of the column 10 on the floor 5. The exhaust air flaps 27 release the exhaust air flow with a pressure difference of 10 Pa each from the clean area 1 into the pressure locks 12, 13 and from there into the environment of the clean area 1 in the building 20. The column 10 absorbs an exhaust air flow of about 80 m 3 / min and each of the exhaust air flaps 27 an exhaust air flow of about 20 m 3 / min .

Zum Herstellen des Sauberkeitsbereichs 1 werden zunächst die Tonne 29, die Stützspinne 19 und die Tragvorrichtung 18 mit dem Filterschlauch 25 und den Beleuchtungselementen sowie die Tragkonstruktionen der Druckschleusen 12, 13 errichtet, auf dem Boden 5 verankert und mit den zugehörigen Feldern der Hülle 6 überzogen. Anschließend werden die weiteren Felder mittels der Reißverschlüsse zu der Hülle 6 verbunden und die Hülle 6 auf dem Boden 5 verankert. Seine endgültige torusartige Form erhält der Sauberkeitsbereich 1 erst, indem er durch den Zuluftschlauch 24 unter den Überdruck gesetzt wird.To create the clean area 1, the barrel 29, the support spider 19 and the support device 18 with the filter hose 25 and the lighting elements as well as the support structures of the pressure locks 12, 13 are first erected, anchored to the floor 5 and covered with the associated fields of the cover 6. The other fields are then connected to the cover 6 by means of the zip fasteners and the cover 6 is anchored to the floor 5 . The cleanliness area 1 only obtains its final torus-like shape when it is subjected to overpressure through the supply air hose 24 .

Zum Abbauen oder Umziehen des Sauberkeitsbereichs 1 wird umgekehrt zunächst der Überdruck abgelassen, die Verankerungen der Hülle 6 am Boden 5 werden gelöst, die Felder der Hülle 6 mittels der Reißverschlüsse getrennt und von der Tonne 29, der Tragvorrichtung 18 und den Tragkonstruktionen der Druckschleusen 12, 13 gelöst. Der Filterschlauch 25 und die Beleuchtung werden von der Tragvorrichtung 18 und schließlich die Tragvorrichtung 18 selbst, die Stützspinne 19, die Tonne 29 und die Tragkonstruktionen der Druckschleusen 12, 13 abgebaut.Conversely, to dismantle or move the cleanliness area 1, the overpressure is first released, the anchoring of the cover 6 on the floor 5 is released, the fields of the cover 6 are separated by means of the zip fasteners and separated from the barrel 29, the supporting device 18 and the supporting structures of the pressure locks 12, 13 solved. The filter hose 25 and the lighting are removed from the support device 18 and finally the support device 18 itself, the support spider 19, the barrel 29 and the support structures of the pressure locks 12, 13.
