Description

Die Erfindung betrifft eine Vorrichtung zum Abdichten von Öffnungen, insbesondere Tür- und Fensteröffnungen, in Gebäuden zum Schutz gegen Hochwasser mit einem Schließkörper zum Verschließen der Öffnung sowie mit einem mit dem Schließkörper im abdichtenden Zustand zusammenwirkenden Dichtkörper.The invention relates to a device for sealing openings, in particular Door and window openings, in buildings for protection against floods with a closing body for closing the opening and with a with the Closing body in the sealing state cooperating sealing body.

Zum Schutz gegen Hochwasser ist es aus der Praxis bekannt, Gebäudeöffnungen, wie beispielsweise Türöffnungen und/oder Fensteröffnungen mit an die Größe der jeweiligen Öffnung angepaßten Platten, insbesondere Stahlplatten, abzudichten. Neben dem hohen Zeit- und Montageaufwand zum Anbringen dieser Abdeckplatten hat diese Art des Hochwasserschutzes den Nachteil, daß die Platten für den jeweiligen Einsatzzweck gut erreichbar im Gebäude bzw. in der Nähe des Gebäudes gelagert werden müssen, wofür wiederum ein großer Platzbedarf notwendig ist.For protection against floods, it is known from practice, building openings, such as door openings and / or window openings with the size of the Each plate adapted to the respective opening, in particular steel plates to seal. In addition to the high time and assembly costs for attaching these cover plates This type of flood protection has the disadvantage that the plates for the respective application easily accessible in the building or in the vicinity of the building need to be stored, which in turn requires a lot of space is.

Weiterhin ist aus dem DE-U-76 05 029 ein Sicherheitsschott für Tore zur Abschirmung gegen Hochwasser bekannt. Dieses bekannte Sicherheitsschott besteht aus einem verwindungssteifen Hohlkörperschott, welches vertikal vor dem abzudichtenden Tor verfahrbar angeordnet ist. Das Verfahren dieses Hohlkörperschotts erfolgt über an dem Hohlkörperschott angreifende, über Umlenkrollen geführte Verbindungsmittel, an deren anderem Ende Kontergewichte angeordnet sind. Durch die Verlagerung dieser Kontergewichte wird das Hohlkörperschott entweder abwärts oder aufwärts bewegt. Neben dem hohen gerätetechnischen Aufwand ist bei diesem Sicherheitsschott nachteilig, daß diese bekannte Konstruktion vor der abzudichtenden Öffnung des Gebäudes angeordnet von außen immer sichtbar ist, weshalb eine solche Vorrichtung zum Abdichten von Fensteröffnungen und/oder Türöffnungen von Wohnhäusern nur in Ausnahmefällen eingesetzt werden wird.Furthermore, from DE-U-76 05 029 a safety bulkhead for gates for shielding known against flood. This well-known security bulkhead consists of a torsionally rigid hollow body bulkhead, which is to be sealed vertically in front of the Tor is arranged movable. The method of this hollow body bulkhead takes place by acting on the hollow body bulkhead, guided over pulleys Connecting means, at the other end counterweights are arranged. By shifting these counterweights, the hollow body bulkhead either moved downwards or upwards. In addition to the high equipment expense is disadvantageous in this safety bulkhead that this known construction before sealed opening of the building arranged from the outside is always visible why such a device for sealing window openings and / or Door openings of residential buildings will be used only in exceptional cases.

Eine weitere Abdichtvorrichtung ist aus der DE-OS 44 37 909 bekannt. Bei dieser bekannten Hochwasserschutzvorrichtung erfolgt das Verschließen von GebäudeÖffnungen über größenmäßig an die jeweilige Gebäudeöffnung angepaßte Abdichteinsätze aus Metall. Das Abdichten gegenüber dem Gebäude sowie das Festlegen dieser Abdichteinsätze in den Gebäudeöffnungen erfolgt über einen mit Druck beaufschlagbaren Dichtkörper, der in einem mit dem Abdichteinsatz verbundenen Profil angeordnet ist. Nachteilig bei dieser bekannten Vorrichtung ist, daß für jede Gebäudeöffnung ein entsprechender einteiliger und somit sperriger und schwerer Abdichteinsatz vorrätig gehalten werden muß, der im Bedarfsfall in die entsprechende Gebäudeöffnung einzusetzen ist. Auch die Handhabung dieser bekannten Vorrichtung ist schwierig, da die einzelnen Abdichteinsätze erst dann selbsttätig in den Gebäudeöffnungen halten, wenn der Dichtkörper mit einem ausreichenden Druck beaufschlagt wurde.Another sealing device is known from DE-OS 44 37 909. At this known flood protection device is the closing of building openings over sized to the respective building opening adapted Abdichteinsätze made of metal. The sealing against the building as well as the Set these sealing inserts in the building openings via a with Pressurized sealing body, which in a connected to the sealing insert Profile is arranged. A disadvantage of this known device, that for each building opening a corresponding one-piece and thus bulkier and heavy sealing insert must be kept in stock, in case of need in the appropriate building opening is to be used. Also, the handling of this known device is difficult because the individual sealing inserts only then hold automatically in the building openings when the sealing body with a sufficient Pressure was applied.

Ausgehend von diesem bekannten Stand der Technik liegt der Erfindung die Aufgabe zugrunde, eine Vorrichtung zum Abdichten von Gebäudeöffnungen zum Schutz gegen Hochwasser zu schaffen, die bei einem verhältnismäßig geringen gerätetechnischen Aufwand eine sichere Abdichtung der Gebäudeöffnung ermöglicht und darüber hinaus das Erscheinungsbild des Gebäudes nur unwesentlich beeinflußt.Starting from this prior art, the invention has for its object to provide a device for sealing building openings to protect against flooding, which enables a secure sealing of the building opening at a relatively low equipment complexity and beyond only marginally affects the appearance of the building ,

Die Lösung dieser Aufgabenstellung ist erfindungsgemäß dadurch gekennzeichnet, daß der Schließkörper als in seitlichen Führungsprofilen geführt vor die zu verschließende Öffnung verfahrbares, auf eine Trommel aufwickelbares bzw. von einer Trommel abwickelbares Rollschott aus einem flexiblen Material, insbesondere Gummi, imprägniertem und/oder beschichtetem textilen Gewebe oder Kunststoff, ausgebildet ist, wobei das Rollschott mit einzelnen, voneinander beabstandeten und parallel zur Drehachse der Trommel angeordneten Versteifungsleisten aus einem biegesteifen Material, insbesondere Federstahl oder verstärktem Kunststoff, versehen ist, daß die Trommel mitsamt einem Antrieb in einer wasserdichten Umhüllung angeordnet ist und daß der Dichtkörper als das Rollschott im abdichtenden Zustand entlang dem gesamten Öffnungsumfang mit Druck beaufschlagende, in den Führungsprofilen angeordnete Druckdichtung ausgebildet ist.The solution of this problem is inventively characterized in that the closing body as guided in lateral guide profiles movable in front of the opening to be closed, wound on a drum or developable from a drum roll-off of a flexible material, in particular rubber, impregnated and / or coated textile fabric or plastic, is formed, wherein the roll-off with individual, spaced apart and arranged parallel to the axis of rotation of the drum stiffening strips of a rigid material, in particular spring steel or reinforced plastic, is provided, that the drum is arranged together with a drive in a watertight enclosure and that the sealing body is formed as the roll-off in the sealing state along the entire opening circumference with pressure acting, arranged in the guide profiles pressure seal.

Durch diese Ausbildung des Schließkörpers als auf eine Trommel aufwickelbares Rollschott ist es möglich den Schließkörper im Ruhezustand, d. h. in dem Zustand, wenn er nicht zum Schutz vor Hochwasser verwendet wird, möglichst platzsparend unterzubringen. Die Trommel zum Aufwickeln des Rollschotts kann beispielsweise im Mauerwerk oberhalb oder unterhalb der abzudichtenden Gebäudeöffnung angeordnet werden.By this design of the closing body as aufwickelbares on a drum Roller shutter, it is possible the closing body at rest, d. H. in that condition, if it is not used to protect against flooding, save as much space as possible accommodate. The drum for winding the roller shutter can, for example arranged in masonry above or below the sealed building opening become.

Die Führungsprofile zum Führen des Rollschotts werden dann vorteilhafterweise seitlich der zu verschließenden Öffnung im Mauerwerk des Gebäudes angeordnet, so daß im nicht verschlossenen Zustand die Vorrichtung zum Abdichten der Gebäudeöffnung so gut wie nicht erkennbar ist. Diese Unauffälligkeit der Vorrichtung im Ruhezustand kann auch dadurch verstärkt werden, daß die seitlichen Führungsprofile durch Blenden abdeckbar sind.The guide profiles for guiding the roller shutter are then advantageously arranged at the side of the opening to be closed in the masonry of the building, so that when not closed the device for sealing the building opening as good as not recognizable. This inconspicuousness of the device at rest can also be reinforced by the fact that the lateral guide profiles can be covered by diaphragms.

Das erfindungsgemäße Rollschott besteht aus einem flexiblen Material, um einerseits ein einwandfreies Aufwickeln bzw. Abwickeln des Rollschotts auf die Trommel zu gewährleisten und andererseits einen zuverlässig abdichtenden Schließkörper bereitzustellen. Die auf dem Material des Rollschotts angeordneten oder in das Material des Rollschotts eingearbeiteten Versteifungsleisten verhindern ein zu starkes Ausbeulen des aus einem flexiblen Material gebildeten Rollschotts aufgrund des Wasserdrucks.The roller shutter according to the invention consists of a flexible material, on the one hand a proper winding or unwinding of the roller shutter on the drum to ensure and on the other hand a reliable sealing closure body provide. The arranged on the material of the roller shutter or in The material of the roller shutter incorporated reinforcing bars prevent one from severe bulging due to the roll bar formed from a flexible material the water pressure.

Die Führungsprofile zum Führen des Rollschotts entlang der zu verschließenden Gebäudeöffnungen sind erfindungsgemäß als zum Rollschott hin offene Hohlprofile, insbesondere U-Profile, ausgebildet.The guide profiles for guiding the roller shutter along the to be closed Building openings are according to the invention as the roll bulkhead open hollow profiles, in particular U-profiles, formed.

Gemäß einer ersten Ausführungsform der Erfindung ist die mit dem Rollschott zusammenwirkende Druckdichtung als aus einem elastischen Material, insbesondere Gummi, imprägniertem und/oder beschichtetem textilen Gewebe oder Kunststoff, bestehender, pneumatisch oder hydraulisch aufpumpbarer Schlauch ausgebildet. Durch die Ausbildung der Druckdichtung als aufpumpbarer Schlauch ist es möglich, zunächst das Rollschott in den Führungsprofilen vor die abzudichtende Gebäudeöffnung zu verfahren und erst anschließend über das Aufpumpen der Druckdichtungen den abdichtenden Anpreßdruck auf das Rollschott zu erzeugen. Durch dieses Aufbringen des Dichtungsdrucks erst nach dem Verfahren des Rollschotts wird sichergestellt, daß beim Verfahren des Rollschotts innerhalb der Führungsprofile keine hohen Reibwiderstände zu überwinden sind, wie dies ansonsten der Fall wäre, wenn das Rollschott beispielsweise entlang einer festmontierten Gummidichtung verschoben würde.According to a first embodiment of the invention, which cooperates with the roller shutter Pressure seal as made of an elastic material, in particular Rubber, impregnated and / or coated textile fabric or plastic, existing, pneumatically or hydraulically inflatable hose formed. By forming the pressure seal as an inflatable tube, it is possible First, the roll-off in the guide profiles in front of the sealed building opening to proceed and only then on the pumping of the Pressure seals to produce the sealing contact pressure on the roll-off. By applying the sealing pressure only after the method of the roller shutter it is ensured that when moving the roller shutter within the guide profiles no high frictional resistance has to be overcome, as otherwise the case would be, for example, if the roll-off along a permanently mounted Rubber seal would be moved.

Gemäß einer zweiten Ausführungsform der Erfindung wird vorgeschlagen, daß die Druckdichtung als mittels Druckfedern in Richtung auf das Rollschott vorgespannte Rollenleiste ausgebildet ist. Diese Art der Ausbildung der Druckdichtung eignet sich insbesondere für kleine Gebäudeöffnungen, bei denen es nicht notwendig ist, einen so hohen Anpreßdruck auf das Rollschott aufzubringen.According to a second embodiment of the invention it is proposed that the Pressure seal biased by means of compression springs in the direction of the roll-off Roller bar is formed. This type of training the pressure seal is suitable especially for small building openings where it is not necessary to apply such a high contact pressure to the roller shutter.

Weiterhin wird mit der Erfindung vorgeschlagen, daß die Trommel zum Aufwickeln bzw. Abwickeln des Rollschotts motorisch, insbesondere mittels eines Pneumatikmotors antreibbar ist. Alternativ zu diesem motorischen Antrieb oder als Ergänzug zu diesem Antrieb wird gemäß einer weiteren Ausführungsform der Erfindung vorgeschlagen, daß die Trommel zum Aufwickeln bzw. Abwickeln des Rollschotts mechanisch antreibbar ist.Furthermore, it is proposed with the invention that the drum for winding or unwinding of the roller shutter motor, in particular by means of a pneumatic motor is drivable. Alternatively to this motor drive or as a supplement to this drive is according to another embodiment of the invention proposed that the drum for winding or unwinding of the roller shutter is mechanically driven.

Bei der Verwendung eines motorischen Antriebs für die Trommel wird gemäß einer bevorzugten Ausführungsform der Erfindung vorgeschlagen, daß für das Aufpumpen der als Schlauch ausgebildeten Druckdichtung sowie zum Antreiben der Trommel derselbe Motor verwendbar ist.When using a motor drive for the drum is according to a preferred embodiment of the invention proposed that for the inflation designed as a hose pressure seal and for driving the Drum the same engine is used.

Die Dichtwirkung zwischen Führungsprofil und Rollschott kann weiterhin dadurch erhöht werden, daß auf den als Anlageflächen für das Rollschott dienenden Innenseiten der Führungsprofile Dichtungen, beispielsweise aus Teflon ®, angeordnet sind. Insbesondere bei der Verwendung von Teflon ® zur Ausbildung dieser Dichtungen ergibt sich nur ein geringer Reibwiderstand bei Verfahren des Rollschotts entlang den Führungsprofilen. The sealing effect between guide profile and roller shutter can continue thereby be increased that on serving as contact surfaces for the roll-off insides the guide profiles seals, for example made of Teflon ® arranged are. Especially when using Teflon ® to form this Gaskets results in only a slight frictional resistance in the method of Rollschotts along the guide profiles.

Um das Rollschott beim Aufwickeln und Abwickeln immer auf Spannung zu halten, wird gemäß einer weiteren Ausführungsform vorgeschlagen, daß an den beiden in den Führungsprofilen gelagerten Seiten des freien Endes des Rollschotts Zugseile befestigt sind, deren anderen Enden jeweils über eine Umlenkrolle am trommelfernen Ende der Führungsprofile umgelenkt derart an der Trommel festgelegt sind, daß die Trommel das Zugseil beim Abrollen des Rollschotts aufwickelt bzw. beim Aufwickeln des Rollschotts abwickelt.In order to keep the roll-off during winding and unwinding always on tension, is proposed according to a further embodiment, that at the two in the guide profiles mounted sides of the free end of the roller shutter traction cables are attached, the other ends in each case via a pulley on the drum remote Deflected at the end of the guide profiles are fixed to the drum, that the drum winds the pull rope when rolling of the roller shutter or when Winding the roller shutter unwinds.

Gemäß einer weiteren Ausführungsform der Erfindung ist das Rollschott als um in den Führungsprofilen angeordnete Führungsstäbe geführtes endloses Band aus einem flexiblen Material ausgebildet.According to a further embodiment of the invention, the roll-off is as in order to The management profiles arranged guide rods guided endless belt formed of a flexible material.

Schließlich wird mit der Erfindung vorgeschlagen, daß sowohl die Trommel zum Aufwickeln bzw. Abwickeln des Rollschotts als auch der Antrieb für die Trommel in einer gegenüber der Umgebung wasserdicht abgedichteten Umhüllung angeordnet sind.Finally, it is proposed with the invention that both the drum for Winding or unwinding of the roller shutter as well as the drive for the drum in disposed opposite the environment watertight sealed enclosure are.

Die in Fig. 1 dargestellte Vorrichtung zum Abdichten von Gebäudeöffnungen besteht im wesentlichen aus in das Mauerwerk einsetzbaren oder auf dem Mauerwerk befestigbaren Führungsprofilen 1, einem in den Führungsprofilen 1 verfahrbaren Rollschott 2 als Schließkörper sowie einer in dem Führungsprofil 1 angeordneten, mit dem Rollschott 2 zusammenwirkenden Druckdichtung 3.The device shown in Fig. 1 for sealing of building openings consists essentially usable in the masonry or on the masonry fastenable guide profiles 1, one in the guide profiles 1 movable Roller shutter 2 as a closing body and one arranged in the guide profile 1, with the roller shutter 2 cooperating pressure seal. 3

Wie aus Fig. 1 ersichtlich, ist das aus elastischem Material gebildete Rollschott 2 auf eine Trommel 4 aufwickelbar bzw. von einer Trommel 4 abwickelbar. Zum Absichern einer Türöffnung ist es beispielsweise möglich, die in einer wasserdichten Umhüllung 5 angeordnete Trommel 4 mitsamt einem Antrieb 6 zum Drehen der Trommel 4 unterhalb der Tür, beispielsweise in einem Treppenabsatz, anzuordnen. Die zur Führung des Rollschotts 2 dienenden Führungsprofile 1 werden dann vorteilhafterweise in dem die Türöffnung umgebenden Mauerwerk der Türwangen 7 sowie des Türsturzes 8 angeordnet, so daß die Vorrichtung im geöffneten Zustand das Erscheinungsbild des mit dieser Vorrichtung versehenen Gebäudes nicht oder nur unwesentlich beeinträchtigt.As can be seen from FIG. 1, the roller shutter formed from elastic material is the second on a drum 4 wound up or unwound from a drum 4. To hedge a door opening it is possible, for example, in a watertight Enclosure 5 arranged drum 4 together with a drive 6 for rotating the Drum 4 below the door, for example, in a landing to arrange. The guiding profiles 1 serving to guide the roller shutter 2 then become advantageously in the surrounding the door opening masonry of the door cheeks 7 and the lintel 8, so that the device in the open state the appearance of the building provided with this device not or only insignificantly affected.

Der genauere Aufbau der in Fig. 1 dargestellten Ausführungsform einer Vorrichtung zum Abdichten einer Gebäudeöffnung ist in den Abbildungen Fig. 2 und 3 zu entnehmen. Wie aus Fig. 1 und 2 ersichtlich ist, ist an beiden in den Führungsprofilen 1 gelagerten Seiten des freien Endes des Rollschotts 2 jeweils ein Zugseil 9 befestigt, welches über jeweils eine Umlenkrolle 10 am trommelfernen Ende der Führungsprofile 1 umgelenkt mit seinem anderen Ende an der Trommel 4 zum Aufwickeln bzw. Abwickeln des Rollschotts 2 befestigt ist. Wie insbesondere aus Fig. 1 ersichtlich, ist das Zugseil 9 so an der Trommel 4 befestigt, daß, wenn sich die in Lagern 11 gelagerte Trommel 10 zum Abwickeln des Rollschotts 2 dreht, das Zugseil 9 auf die Trommel 4 aufgewickelt wird. Durch dieses Gegenspiel von Abwickeln des Rollschotts 2 und Aufwickeln des Zugseils 9 wird sichergestellt, daß das Rollschott 2 immer auf Spannung gehalten wird.The detailed structure of the embodiment of a device shown in Fig. 1 for sealing a building opening is in Figs. 2 and 3 to remove. As can be seen in FIGS. 1 and 2, both are in the guide profiles 1 stored sides of the free end of the roller shutter 2 each have a pull cable. 9 attached, which in each case via a guide roller 10 at the drum remote end of Guide profiles 1 deflected with its other end to the drum 4 for Winding or unwinding of the roller shutter 2 is attached. As in particular from Fig. 1 can be seen, the pull cable 9 is fixed to the drum 4, that when the drum 10 mounted in bearings 11 rotates to unwind the roller shutter 2, the traction cable 9 is wound on the drum 4. Through this counterplay of Unwinding of the roller shutter 2 and winding the traction cable 9 ensures that the roll-off 2 is always kept on tension.

Der Aufbau der in dem Führungsprofil 1 angeordneten Druckdichtung 3 ist der Abbildung 3 zu entnehmen. In dargestelltem Ausführungsbeispiel besteht die Druckdichtung 3 aus einem aus einem elastischen Material gebildeten Schlauch 3a. Zum Andrücken des Rollschotts gegen die Innenseite des Führungsprofils 1 kann dieser Schlauch 3a pneumatisch oder hydraulisch aufgepumpt werden. Der beispielsweise mit einem Druck von 4 bar aufgepumpte Schlauch 3a füllt dann vollständig den Raum zwischen der anderen Innenseite des Führungsprofils 1 und dem in dem Führungsprofil 1 angeordneten Rollschott 2 aus, so daß das Rollschott 2 abdichtend gegen die Innenseite des Führungsprofils 1 gedrückt wird. Um Materialunebenheiten und eventuelle Verunreinigungen auszugleichen, kann auf der zur Anlage des Rollschotts 2 dienenden Innenseite des Führungsprofils 1 zusätzlich eine Dichtung 12 angeordnet werden. Um durch diese Dichtung 12 den Reibungswiderstand beim Verfahren des Rollschotts 2 innerhalb der Führungsprofile 1 so gering wie möglich zu halten, wird als Material für die Dichtung 12 insbesondere Teflon ® verwendet.The structure of arranged in the guide profile 1 pressure seal 3 is the figure 3 to remove. In illustrated embodiment, the pressure seal 3 made of a hose 3a formed of an elastic material. For pressing the roller shutter against the inside of the guide profile 1 can this hose 3a be inflated pneumatically or hydraulically. The example with a pressure of 4 bar inflated tube 3a then fills completely the space between the other inside of the guide profile 1 and the arranged in the guide profile 1 roller 2, so that the roll-off 2 is pressed sealingly against the inside of the guide profile 1. Around Material irregularities and any impurities can balance the serving for the installation of the roller shutter 2 inside of the guide profile 1 in addition a seal 12 are arranged. To pass through this seal 12 the Friction resistance when moving the roller shutter 2 within the guide profiles 1 as low as possible, is used as the material for the seal 12 in particular Teflon® used.

Die Abbildung Fig. 3 zeigt, daß es beim Einbau dieser Ausführungsform der Vorrichtung gleichgültig ist, von welcher Seite das abzuhaltende Wasser gegen das Rollschott 2 drückt, da in jedem Fall eine vollständige Abdichtung zwischen Rollschott 2 einerseits und Führungsprofil 1 andererseits aufgrund des über die Druckdichtung 3 aufgebrachten Drucks gewährleistet ist.Figure 3 shows that when installing this embodiment of the device It does not matter from which side the water to be held against the Roller 2 presses, as in any case a complete seal between the roll-off 2 on the one hand and leadership profile 1 on the other hand due to the on the Pressure seal 3 applied pressure is guaranteed.

Da es zum Aufwickeln des Rollschotts 2 auf die Trommel 4 notwendig ist, das Rollschott 2 aus einem elastischen Material, wie beispielsweise Gummi, imprägniertem und/oder beschichtetem textilen Gewebe oder Kunststoff herzustellen, ist es zum Abdichten großer Türöffnungen vorteilhaft, wenn das Rollschott 2 einzelne, voneinander beanstandete und parallel zur Drehachse der Trommel 4 angeordnete Versteifungsleisten 13 aus einem biegesteifen Material aufweist, die verhindem, daß das Rollschott 2 aufgrund des Wasserdrucks und der Elastizität des Materials des Rollschotts 2 so stark eingerückt wird, daß es aus der Führung der Führungsprofile 1 herausrutscht. Als Materialien für die Versteifungsleisten 13 eignen sich insbesondere Federstahl und verstärkte Kunststoffe, beispielsweise glasfaser- oder karbonfaserverstärkte Kunststoffe.Since it is necessary for winding the roller shutter 2 on the drum 4, the Roller shutter 2 made of an elastic material, such as rubber, impregnated and / or coated textile fabric or plastic is it is advantageous for sealing large door openings when the roll-off door 2 individual, objected to each other and arranged parallel to the axis of rotation of the drum 4 Stiffening strips 13 made of a rigid material that prevent, that the roller shutter 2 due to the water pressure and the elasticity of Material of the roller shutter 2 is engaged so strong that it is out of the leadership of the Guide profiles 1 slips out. Suitable materials for the stiffening strips 13 in particular spring steel and reinforced plastics, for example glass fiber or carbon fiber reinforced plastics.

Bei dem in Fig. 4 und 5 dargestellten zweiten Ausführungsbeispiel einer Vorrichtung zum Abdichten von Gebäudeöffnungen ist die Druckdichtung 3 als Rollenleiste 3b ausgebildet, die mittels Druckfedern 3c in Richtung auf das Rollschott 2 vorgespannt ist. Diese Ausführungsform, bei der keine Druckmittelanschlüsse für die Druckdichtung 3 notwendig sind, eignet sich insbesondere zur Abdichtung kleiner'Gebäudeöffnungen. In the illustrated in Fig. 4 and 5 the second embodiment of a device for sealing building openings is the pressure seal 3 as a roller bar 3b formed by means of compression springs 3c in the direction of the roller shutter. 2 is biased. This embodiment, in which no pressure fluid connections for the pressure seal 3 are necessary, is particularly suitable for sealing kleiner'Bebäudeöffnungen.

Die voranstehend beschriebenen Vorrichtungen zum Abdichten von Gebäudeöffnungen zum Schutz gegen Hochwasser zeichnen sich dadurch aus, daß das auf die Trommel 4 aufwickelbare bzw. von der Trommel 4 abwickelbare Rollschott im aufgewickelten Zustand sehr wenig Platz benötigt und so in das Mauerwerk der abzudichtenden Gebäudeöffnung einsetzbar ist, daß diese das Erscheinungsbild des Gebäudes - wenn überhaupt - nur unwesentlich beeinflußt. Die bei den dargestellten Ausführungbeispielen als U-förmige Profile ausgebildeten Führungsprofile 1 können darüber hinaus im Ruhezustand durch eine (nicht dargestellte) Abdeckung verschlossen werden, so daß auch die Führungsprofile 1 so gut wie nicht in Erscheinung treten.The above-described devices for sealing building openings for protection against floods are characterized by the fact that on the drum 4 wound or unfoldable from the drum 4 roll-off in the wound state requires very little space and so in the masonry of the can be used to seal the building opening that this is the appearance of the building - if at all - only insignificantly influenced. The at the illustrated Exemplary embodiments designed as U-shaped profiles guide profiles 1 can also be at rest by a (not shown) cover be closed, so that the guide profiles 1 as well as not appear.

Der Antrieb der Trommel 4 zum Aufwickeln bzw. Abwickeln des Rollschotts 2 erfolgt vorteilhafterweise motorisch, insbesondere über einen als Antrieb 6 dienenden Pneumatikmotor. Der Pneumatikmotor kann dabei so geschaltet werden, daß er einerseits zum Aufwickeln bzw. Abwickeln des Rollschotts 2 dient und andererseits als Kompressor betreibbar ist, um den notwendigen Abdichtdruck in den als Schläuche 3a ausgebildeten Druckdichtungen 3 aufzubauen. Die in den Abbildungen Fig. 1 und 4 dargestellten Ausführungsformen zeichnen sich weiterhin dadurch aus, daß das Rollschott 2 vertikal von unten nach oben vor die zu verschließende Gebäudeöffnung verfahrbar ist, so daß das Rollschott dem steigenden Hochwasser angepaßt nach oben verfahrbar ist. Es ist somit nicht notwendig, zu Beginn des Hochwassers gleich die gesamte Öffnung, insbesondere Türöffnung zu verschließen, so daß ein Verlassen des Gebäudes durch diese Türöffnung nicht mehr möglich wäre.The drive of the drum 4 for winding or unwinding of the roller shutter 2 takes place Advantageously motor, in particular via serving as a drive 6 Pneumatic motor. The pneumatic motor can be switched so that he serves on the one hand for winding or unwinding of the roller shutter 2 and on the other as a compressor is operable to provide the necessary sealing pressure in the Hoses 3a trained pressure seals 3 build. The in the pictures FIGS. 1 and 4 are further characterized by this from that the roll-off 2 vertical from bottom to top in front of the to be closed Building opening is movable, so that the roll-off the rising Flood adjusted adapted to move upwards. It is therefore not necessary to Beginning of the flood equal to the entire opening, especially door opening to close, so that leaving the building through this door opening is not more would be possible.

Zusätzlich oder auch alternativ zu dem motorischen Antrieb 6 für die Trommel 4 ist es auch möglich, die Trommel 4 mechanisch, beispielsweise über eine Kurbel zu betätigen, so daß auch im Falle eines Stromausfalls das Rollschott 2 verschlossen werden kann. Der Druckaufbau für die als Schläuche 3a ausgebildeten Druckdichtungen 3 erfolgt in diesem Fall über separate Druckmittelflaschen. In addition or alternatively to the motor drive 6 for the drum 4 is It is also possible, the drum 4 mechanically, for example via a crank operate, so that even in the case of a power failure, the roller shutter 2 closed can be. The pressure build-up for the formed as hoses 3a pressure seals 3 takes place in this case via separate pressure fluid bottles.
