Abstract

Roofing covers (5) are fixed both sides to the scaffold frames round the building by belts and eyelets and are topped by overpressurized double-chamber supporting elements in elliptical section and supported in turn by a pressure sleeve (7) built in the cover (5). The sleeves are furnished with fill, deflation and safety valves and the supporting elements extend right over th building from side to side. The main elements are themselves supported at intervals by crossways supporting elements laid betwee the main elements. The two sets of elements come in elliptical form and are paired up to form pockets (8) both sides in which th pressure sleeves (7) are inserted without permanent fixing. Each pocket (8) presents a belt fixed on one side (8a) by stitch, we or bond to the cover (5) and the center part of the pocket (8b) is of greater extent than the distance (B) between the two belt strips (8a) fixed to the cover. The result is two cavities (9) both sides of the cover so the pockets also shape up elliptically both sides of the cover as also the main supporting elements once the inserted pressure sleeves (7) have been inflated.

Description

Die Erfindung gehört zum technischen Gebiet des Bauwesens und betrifft hierbei Zelte und Schutzdächer, dabei insbesondere temporäre Schutzüberdachungen, die sich als durch Gasdruck ausgesteifte sowie mittels elastischer Körper gebildete und getragene Konstruktionen darstellen und ohne Traggerüste aus starren, festen Materialien auskommen, nach den Merkmalen des Oberbegriffs der Hauptansprüche dieser technischen Lehre.The invention belongs to the technical field of construction and relates to tents and canopies, especially temporary ones Protective canopies that are braced by gas pressure as well as by means of represent elastic bodies formed and supported constructions and without supporting frames made of rigid, solid materials, according to the Features of the preamble of the main claims of this technical teaching.

Allgemein bekannt sind Überdachungen, die an oder auf Gerüste herkömmlicher Art an- bzw. aufgesetzt werden.
Bei der Bauweise Gitterträger mit Planen werden die im Gerüstbau verwendeten Gitterträger, z.B. 45 cm hoch, auf das Gerüst aufgesetzt und verschraubt. Zusätzlich werden diese an ihren Ober- bzw. Untergurten mit Stahlrohren ausgesteift. Zwischen den Trägern werden Planen angebracht, die mit Hilfe von Bindern, Stricken oder sogenannten Kederschienen miteinander verbunden werden. Nachteilig bei dieser herkömmlichen technischen Lösung ist, daß sich "Wassersäcke" in den Überdachungsplanen bilden, da ein straffes Spannen der Planen von Hand kaum möglich ist. Selbst wenn Spannmittel benutzt würden, ist ein solches straffes Spannen der Planen, daß keine Einwölbung in Schwerkraftrichtung, Durchhängen, erfolgt, technisch nicht möglich, da hierbei das materialabhängige Festigkeits- sowie Relaxations-/Retardationsverhalten dieser in Frage kommenden Werkstoffe unüberschreitbare Grenzen setzt. Eine absolute Wasserdichtheit des Daches kann nicht gewährleistet werden, da die Verknüpfungspunkte der Planen an den Trägern dies nicht ermöglichen. Die Spannweite der Gitterträger ist bei den als bekannt geltenden Systemen, z.B. Layer, auf Grund der zu berücksichtigenden Schneelasten in allen Ausführungsvarianten, z.B. auf 16 m, begrenzt. Der Einsatz dieser v.g. Bauweise ist nur begrenzt möglich, da ab einer Überdachungshöhe von mehr als 3 m zusätzliche statische Unterstützungen erforderlich sind. Zur Montage ohne technische Hilfsmittel, z.B. mittels Kran, können größtenteils nur Aluminiumträger eingesetzt werden, welche dann ca. 30 % höhere Anschaffungskosten gegenüber Stahlträgern verursachen.
Bei der Bauweise Kassettendach werden anstatt der Gitterträger sogenannte Schwerlastgitterträger, z.B. 75 cm hoch, mit Hilfe eines Kranes auf das Gerüst montiert und verschraubt. Entsprechend der statischen Erfordernisse muß daher das Gerüst mit einem Mehraufwand an Kosten und Material als Traggerüst ausgebildet sein. Danach werden die Schwerlastgitterträger mittels Kassettenplatten miteinander verbunden. Die Änderung der Regelausführung eines Gerüstes zu einem Traggerüst erfordert die Erstellung einer statischen Berechnung nach den gesetzlichen Vorschriften und deren Abnahme. Dieser Mehraufwand bedeutet eine enorme "Kostenexplosion" und zusätzlich sehr hohen Materialaufwand. Zusätzliche Flächen für Vormontage, Kranstellplatz und Lkw-Zufahrt werden erforderlich, die nicht in jedem Falle gegeben sind. Im Gegensatz zu vielleicht noch durchscheinenden Planen ist beim Kassettendach noch zusätzlich für eine Ausleuchtung Sorge zu tragen, gegebenenfalls durch den Einbau von Lichtkuppeln oder anderen Beleuchtungseinrichtungen, die eine weitere Kosten- und Arbeitszeiterhöhung verursachen. Weitere nachteilige Wirkungen dieser beiden allgemein bekannten und auch herkömmlich angewandten technischen Verfahrensweisen bestehen darin, daß einerseits auf Grund der winkligen Bauform in ungünstigen Lagen die angreifende Windlast einen weiteren Unsicherheits- bzw. Gefährdungsfaktor darstellt, der nur durch weitere zusätzliche darauf bezogene Sicherungsmaßnahmen minimiert werden kann und andererseits auf Grund von Undichtheiten an den Befestigungsstellen der Schutzplanen an den Gerüsten eine Beheizbarkeit mit konstantem Temperatumiveau nicht gewährleistbar ist. Damit eignen sich diese beiden Schutzdachausführungen, einschließlich ihrer möglichen Modifikationen nur für den Wetterschutz. Für weitere Anwendungsgebiete, wie z.B. Betonsanierungsmaßnahmen oder Korrosionsschutzmaßnahmen ist hiermit keine Einsatzmöglichkeit gegeben, da dabei z.B. bestimmte Oberflächen- und Verarbeitungstemperaturen gewährleistet sein müssen und bei der Beheizung der Einhausung Kondensatwasser an der Unterseite des Schutzdaches gebildet wird. Durch gegebenenfalls vorhandene Ösen an den Schutzplanen kann Wasser eintreten. U.U. werden weitere technische und räumliche Voraussetzungen notwendig, bei deren Fehlen die vorbeschriebenen technischen Lösungen nicht einsetzbar sind; jedenfalls sind sie mit enormen Kosten-, Materialaufwand- und Arbeitszeiterhöhungen verbunden. Oftmals sind Bauherren bzw. Auftraggeber nicht in der Lage, solche Mehrbelastungen zu tragen.
Um temporäre Überdachungen zu realisieren, ist es denkbar, Folien/Planenzelte für sich allein oder in Kombination mit Gerüsten, Rahmen oder ähnlichem einzusetzen.
Der Katalog "Zelte LANCO Erzeugnisse" der Firma Dr. Lange GmbH u.Co.KG, Hannover aus dem Jahre 1997 offenbart und bietet an einen Zeltaufbau, wobei ein luftgetragenes, bogenförmiges Gerüst eingesetzt wird. Dieses besteht aus einem Außenmantel und einem inneren Schlauch. Jeder Gerüstbogen ist unabhängig und kann einzeln ausgewechselt werden. Bei einem Defekt dieses Innenschlauchs fällt dieser aus und gefährdet in erheblichem Maße die Stabilität der Gesamtanordnung Zelt. Darüber hinaus ist dieser Schlauch auch in seiner bogenförmigen Gestaltung hinsichtlich seiner eigenen Stabilität bei Lasterhöhung und/oder Weitenausdehnung stark eingeschränkt und kann Sicherheitsrisiken in sich bergen, da ab einer bestimmten, kaum vorher einschätzbaren Belastung das solch einem gasgefüllten Schlauch innewohnende Einknicken plötzlich erfolgen kann.
Eine Firmenschrift von A&S Luftparadiese, DE bietet Zelte an, die aus dicht nebeneinander befindlichen Schläuchen in der Form von runden oder vieleckigen Bögen bestehen und wie Rippen angeordnet sind und auf diese Weise die Breite des Bauwerkes bilden, wobei alles in dieser Offenbarung darauf hindeutet, daß diese Schläuche nicht doppelwandig ausgebildet sind, da diese Stützrippenzelte durch Vernähen hergestellt werden und damit wegen der Undichtheit der Stützrippenschläuche ständig mittels Gebläse nachgefüllt werden müssen. Die betreffend den LANCO-Zeltaufbau dargestellten Sicherheitsbedenken und Einsatzbeschränkungen gelten hier in noch stärkerem Maße.
Die DE OS 44 21 080 schlägt eine technische Lösung für ein Großraumzelt vor, bei dem ein Traggerüst aus einzelnen aufblasbaren Trägern vorgesehen ist, die torförmig die zu überspannende Fläche von einer Seitenwand zur gegenüberliegenden Seitenwand überragen und mit Abstand voneinander angeordnet sind. Je nach Größe oder Länge des Zeltes wird die Anzahl der Träger variiert. Das Traggerüst ist analog zu den LANCO-Zelten aus einzelnen aufblasbaren Trägern, die aus einer äußeren Hülle und einem inneren mit Druckluft beaufschlagten Schlauchelement bestehen gebildet. Zwischen den die Fläche überspannenden aufblasbaren Trägern sind Befestigungs- und sogenannte Stützelemente für die Zeltplane in Form von Latten angeordnet. Zur Formgebung dieses Großzeltes sind spezielle und speziell geformte Mantelbogenstücke notwendig, die im Dachbereich in Dachstützen übergehen. Im vertikalen Bereich sind vertikale Seitenstützen vorgesehen. Im Bereich des Fuß- bzw. Erdbodens sieht diese Lehre spezielle topfförmige Basisteile vor, einerseits mit Anschlüssen für die Druckluftbeaufschlagung der Innenschläuche, andererseits zur Befestigung der aufgeblasenen Träger mittels dieser Basisteile am Fuß- bzw. Erdboden. Nach dieser technischen Lehre sollen die aufblasbaren/aufgeblasenen Träger ausdrücklich einen runden Querschnitt aufweisen. Der wesentlichste Mangel dieser technischen Lösung besteht darin, daß ein einziger, relativ großräumiger, mit rundem Querschnitt versehener Schlauch zur Druckaufnahme vorgesehen ist. Dabei werden alle oben genannten Mängel in Bezug auf die Stabilität, insbesondere die, die durch das Abknicken des mit Überdruck beaufschlagten Einzelschlauches bei höheren Belastungen beeinflußt wird und in Bezug auf das Defektverhalten, zur Wirkung kommen, wobei diese nach der DE OS 44 21 080 bekanntgemachte technische Lösung einen noch komplizierteren Aufbau, weil noch mehr Einzelteile, und eine geringere Stabilität und Funktionssicherheit aufweisen wird als die technische Lösung der LANCO-Zelte.
Canopies that are attached to or placed on scaffolding of conventional type are generally known.
In the construction of lattice girders with tarpaulins, the lattice girders used in scaffolding, for example 45 cm high, are placed on the scaffolding and screwed together. In addition, these are braced on their upper and lower chords with steel tubes. Tarpaulins are attached between the girders, which are connected to each other with the help of ties, ropes or so-called welt rails. A disadvantage of this conventional technical solution is that "water bags" form in the roof tarpaulin, since it is hardly possible to tighten the tarpaulin by hand. Even if clamping devices were used, such a tight tensioning of the tarpaulins that there is no arching in the direction of gravity, sagging, is technically not possible, since the material-dependent strength and relaxation / retardation behavior of these materials in this case imposes limits that cannot be exceeded. An absolute watertightness of the roof cannot be guaranteed because the connection points of the tarpaulins on the beams do not make this possible. The span of the lattice girders is limited in the known systems, for example layers, due to the snow loads to be taken into account in all design variants, for example to 16 m. The use of this type of construction is only possible to a limited extent, since additional static supports are required from a roof height of more than 3 m. For the assembly without technical aids, for example by means of a crane, mostly only aluminum beams can be used, which then cause approx. 30% higher acquisition costs compared to steel beams.
In the cassette roof design, instead of the lattice girder, so-called heavy-duty lattice girders, e.g. 75 cm high, are mounted and screwed onto the scaffolding using a crane. In accordance with the static requirements, the scaffold must therefore be designed as a supporting scaffold with an additional outlay in terms of cost and material. The heavy-duty lattice girders are then connected to one another by means of cassette plates. Changing the standard version of a scaffold to a supporting scaffold requires the creation of a static calculation according to the legal regulations and its acceptance. This additional effort means an enormous "cost explosion" and also very high material costs. Additional space for pre-assembly, crane parking and truck access are required, which are not always available. In contrast to perhaps still translucent tarpaulins, additional care must be taken to ensure that the cassette roof is illuminated, if necessary by installing light domes or other lighting devices that cause a further increase in costs and working hours. Further disadvantageous effects of these two generally known and also conventionally applied technical procedures are that, on the one hand, due to the angular design in unfavorable locations, the attacking wind load represents a further uncertainty or hazard factor that can only be minimized by additional additional safety measures related to it on the other hand, due to leaks at the fastening points of the protective tarpaulins on the scaffolding, heating with a constant temperature level cannot be guaranteed. These two canopy designs, including their possible modifications, are therefore only suitable for weather protection. For other areas of application, such as concrete renovation measures or corrosion protection measures, there is no possible use because, for example, certain surface and processing temperatures must be guaranteed and condensation water is formed on the underside of the protective roof when the housing is heated. Water may enter through eyelets on the tarpaulins. Under certain circumstances, further technical and spatial requirements are necessary, in the absence of which the above-described technical solutions cannot be used; in any case, they are associated with enormous increases in costs, material costs and working hours. Builders or clients are often unable to bear such additional burdens.
In order to realize temporary roofing, it is conceivable to use foils / tarpaulin tents on their own or in combination with scaffolding, frames or the like.
The catalog "Tents LANCO products" from Dr. Lange GmbH u.Co.KG, Hanover from 1997, reveals and offers a tent structure using an airborne, arched scaffold. This consists of an outer jacket and an inner hose. Each scaffold arch is independent and can be replaced individually. If this inner tube is defective, it fails and jeopardizes the stability of the entire tent arrangement to a considerable extent. In addition, this tube is also very limited in its arcuate design with regard to its own stability when increasing the load and / or extending it, and it can involve safety risks, since from a certain, hardly predictable load, the buckling inherent in such a gas-filled tube can suddenly occur.
A company publication from A&S Luftparadiese, DE offers tents that consist of hoses located close to each other in the form of round or polygonal arches and are arranged like ribs and thus form the width of the structure, with everything in this disclosure indicating that these hoses are not double-walled, since these supporting rib tents are produced by sewing and must therefore be constantly refilled by means of a blower because of the leakage of the supporting rib hoses. The safety concerns and restrictions regarding use of the LANCO tent structure apply here even more.
DE OS 44 21 080 proposes a technical solution for a large tent, in which a supporting structure is provided made up of individual inflatable carriers which project in a gate shape from a side wall to the opposite side wall and are arranged at a distance from one another. Depending on the size or length of the tent, the number of carriers is varied. Like the LANCO tents, the supporting structure is made up of individual inflatable carriers, which consist of an outer shell and an inner hose element to which compressed air is applied. Fastening and so-called support elements for the tarpaulin in the form of slats are arranged between the inflatable supports spanning the surface. The shape of this large tent requires special and specially shaped jacket elbow pieces that merge into roof supports in the roof area. Vertical side supports are provided in the vertical area. In the area of the floor or floor, this teaching provides for special pot-shaped base parts, on the one hand with connections for pressurizing the inner hoses with compressed air, and on the other hand for fastening the inflated supports to the floor or floor using these base parts. According to this technical teaching, the inflatable / inflated carriers should expressly have a round cross section. The main shortcoming of this technical solution is that a single, relatively large, round cross-section hose is provided for pressure absorption. All of the above-mentioned shortcomings with regard to stability, in particular those which are influenced by the kinking of the single hose subjected to excess pressure at higher loads and in relation to the defect behavior, come into effect, these being disclosed according to DE OS 44 21 080 technical solution an even more complicated structure, because even more individual parts, and will have less stability and functional reliability than the technical solution of the LANCO tents.

Die Schrift US-A-3899853 offenbart die technische Lösung einer Zeltkonstruktion, welche aus einer Zeltplane aus Kunststofffolie und mehreren, in Längsrichtung des Zeltes gesehen, parallel zueinander angeordneten, von der einen Seite des Zeltes zu seiner anderen Seite verlaufenden, jedoch nicht wie bei DE OS 44 21 080 in abgeknickter sondern in gewölbter Form bestehenden, luftgefüllten Träger-Taschen bzw. Träger-Schläuchen bzw. Lufttragelementen besteht. Diese wiederum bestehen jeweils aus einem einzigen Luftschlauch, der auf der Ober- bzw. Außenseite des Zeltes angeordnet ist, weswegen diese Anordnung sehr empfindlich gegen von außen einwirkende Stich- oder Schnittverletzungen, gleichfalls wie die vorgenannte Offenbarung nach DE OS 44 21 080, ist. Wie die Offenbarung aber weiter zeigt, können aber auch in der Träger-Taschen bzw. im Träger-Schlauch ein zweiter im wesentlichen konzentrisch angeordneter Schlauch, vorgesehen sein. Der äußere Träger-Schlauch kann dann als Schutzschlauch vorgesehen sein oder selbst mit Luft gefüllt sein, wobei hierbei die Knickstabilität bei höheren Belastungen wegen der im wesentlichen konzentrischen Anordnung nicht verbessert ist. Als Schutzschlauch würde er seine Funktion gegen von außen einwirkende Stich- oder Schnittverletzungen in einem gewissen Maße wohl erfüllen. Zuzüglich wurde über den Träger-Taschen bzw. dem Träger-Schlauch eine zweite Kunststofffolie angeordnet, welche als weiterer Schutz, z.B. zur Temperaturisolierung bei kaltem Wetter, dienen soll.US-A-3899853 discloses the technical solution to one Tent construction, which consists of a tarpaulin made of plastic film and several seen in the longitudinal direction of the tent, arranged parallel to each other, by one side of the tent running to the other, but not as in DE OS 44 21 080 in kinked but in arched form existing, air-filled carrier bags or carrier hoses or Air support elements exist. These in turn consist of one single air hose on the top or outside of the tent is arranged, which is why this arrangement is very sensitive to external stab or cut injuries, also like that aforementioned disclosure according to DE OS 44 21 080, is. Like revelation but shows further, but can also in the carrier bags or in the carrier tube a second essentially concentrically arranged hose, be provided. The outer carrier hose can then be used as a protective hose be provided or even be filled with air, with the Kink stability at higher loads because of the essentially concentric arrangement is not improved. As a protective hose, he would its function against external stab or cut injuries to a certain extent. Plus was made over the carrier bags or a second plastic film is arranged on the carrier hose, which as further protection, e.g. for temperature insulation in cold weather, should serve.

Erfindungsgemäß wird die Aufgabe durch die Anspruchsmerkmale gelöst.
An der Oberkante eines Gerüstes welches das Bauwerk umgebend erstellt wurde, dort an dessen Gerüstrahmen oder an einem Grundrahmen aus Gerüstrohren wird mittels Spanngurten und weiteren üblichen und geeigneten Spannelementen vermittels der Ösen an einer Überdachungsplane diese dort befestigt. Auf dieser Überdachungsplane sind mit Überdruck gegenüber dem athmosphärischen Druck ausgestattete Doppelkammertragelemente mit ellipsenförmigem Querschnitt angeordnet. Dieser elliptische Querschnitt ergibt sich durch jeweils einen auf der Innenseite und einen auf der Außenseite der Überdachungsplane in die Doppelkammertragelemente eingefügten Druckschlauch. Diese Druckschläuche sind in vorbekannter Art und Weise mit Füll-, Ablaß- sowie Sicherheitsventilen ausgestattet. Die Doppelkammertragelemente erstrecken sich bogenüberspannend von der einen Seite des zu überdachenden Bauwerkes von deren Befestigungselemente hin zur anderen Seite des Bauwerkes bis zu deren Befestigungselemente. Es sind darüber hinaus gleiche Doppelkammertragelemente auf der Überdachungsplane jeweils zwischen den Bögen parallel zur Befestigungslinie am Gerüst oder Grundrahmen in einem von den jeweiligen konkreten Gegebenheiten abhängigen Abstand voneinander angeordnet. Die Doppelkammertragelemente sind in ihrer ellipsenförmigen Gestalt dadurch gebildet, daß paarweise, somit auf jeder Seite der Überdachungsplane, eine Gurttasche auf der Planenoberfläche, innen und am gleichen Ort gegenüberliegend außen, angebracht ist, in der jeweils ein Druckschlauch, nicht dauerhaft befestigt, eingelegt ist. Die Gurttasche ist aus einem Band gebildet, welches an seinen beiden Seiten fest und dauerhaft mit der Überdachungsplane durch beispielsweise Nähen, Kleben oder Schweißen verbunden ist aber der freie, nicht befestigte Mittelbereich der Gurttasche eine größere Ausdehnung besitzt, als der innere Abstand zwischen den beiden Befestigungsstreifen der Gurttasche auf der Überdachungsplane aufweist, wodurch sich zwei Hohlräume beidseits der Überdachungsplane bilden und, paarweise gesehen, eine ellipsenförmige Aufwölbung beider Gurttaschen beidseits der Überdachungsplane und damit des hierdurch gebildeten Doppelkammertragelementes bei Druckbeaufschlagung der in die Gurttaschen eingefügten Druckschläuche gegeben ist. Nach dem Einfügen und Befüllen der beiden Druckschläuche bilden diese eine erzwungene gemeinsame Fläche an der Ebene der Überdachungsplane, gegebenenfalls unter Verwendung von Beilagen, auf der eine gegenseitige Abstützung erfolgt, mit dem Ergebnis, daß sich die Knickstabilität dieses Mehrschlauchsystems erhöht. Somit ist auch denkbar, daß gleichwirkende Austauschmittel nicht auf den Einsatz zweier Schläuche beschränkt sein werden, sondern daß gegebenenfalls mehrere Schläuche in solch einer Gurttaschenanordnung als äquivalent wirkende Mittel zu betrachten sind.
According to the invention, the object is achieved by the features of the claims.
On the top edge of a scaffold that was built around the building, there on its scaffold frame or on a base frame made of scaffold tubes, the eyelets are attached to a roof tarpaulin by means of lashing straps and other customary and suitable tensioning elements. Double chamber support elements with an elliptical cross section are provided on this roofing tarpaulin with overpressure compared to the atmospheric pressure. This elliptical cross section results from a pressure hose inserted on the inside and one on the outside of the roof tarpaulin into the double-chamber support elements. These pressure hoses are equipped in a known manner with filling, drainage and safety valves. The double-chamber support elements extend across the arch from one side of the building to be roofed from its fastening elements to the other side of the building up to its fastening elements. In addition, identical double-chamber support elements are arranged on the roof tarpaulin, each between the arches parallel to the fastening line on the scaffold or base frame, at a distance from one another which is dependent on the respective specific circumstances. The double-chamber support elements are formed in their elliptical shape by attaching a belt pocket in pairs, i.e. on each side of the roof tarpaulin, on the surface of the tarpaulin, inside and at the same location opposite, in each of which a pressure hose, not permanently attached, is inserted. The belt bag is formed from a band, which is firmly and permanently connected to the roofing tarpaulin on both sides by, for example, sewing, gluing or welding, but the free, non-fastened central region of the belt bag has a greater extent than the inner distance between the two fastening strips of the belt pocket on the roof tarpaulin, whereby two cavities are formed on both sides of the roof tarpaulin and, seen in pairs, there is an elliptical bulge of both belt pockets on both sides of the roof tarpaulin and thus the double chamber support element thus formed when the pressure hoses inserted into the belt pockets are pressurized. After the two pressure hoses have been inserted and filled, they form a forced common surface at the level of the roofing tarpaulin, possibly with the use of supplements on which there is mutual support, with the result that the kink stability of this multi-hose system increases. It is therefore also conceivable that exchange means having the same effect will not be limited to the use of two hoses, but that, if necessary, several hoses in such a belt pocket arrangement are to be regarded as means having an equivalent effect.

Eine weitere besondere Ausgestaltung dieser technischen Lehre ist darin zu sehen, daß ein Austausch des gasförmigen Mediums in den Hohlräumen der Druckschläuche durch einen schnell ausreagierenden Kunststoffschaum vorgesehen ist. Dies kann nach dem Befüllen der Hohlräume mit dem gasförmigen Medium durch ein Nachfüllen des Schaumes und ein Verdrängen des gasförmigen Mediums realisiert werden.
Auch ist als weitere Alternative eine Kombination von Doppelkammerelementen, die mit gasförmigem Medium gefüllt sind, mit solchen, die mit Kunststoffschaum gefüllt sind, möglich und dies auch noch mit unterschiedlichen Dimensionierungen. Damit kann die so erfolgte Ausführung der Tragegerüstanordnung bereichsweise den jeweiligen Erfordernissen der Statik im jeweiligen Bereich der Gesamtkonstruktion angepaßt werden.
Bei der Erstellung dieser temporären Schutzüberdachung wird in vorbekannter Weise auf einem am Bauwerk errichteten Gerüst an seiner oberen Begrenzung oder an einem herzustellenden Grundrahmen aus Gerüstrohren mittels herkömmlicher Befestigungselemente sowie mittels Spanngurte und den in der Überdachungsplane befindlichen Ösen diese Überdachungsplane mit ihren Doppelkammertragelementen beidseitig und das Bauwerk überspannend befestigt. Danach werden die Druckschläuche in diesem flexiblen Traggerüst mit Druckluft befüllt, wodurch sich die Überdachung aufwölbt und ein Schutzdach ausbildet, gegebenenfalls wird ein Austausch des gasförmigen Mediums durch schnell reagierenden Kunststoffschaum vorgenommen.
Die vorteilhaften Wirkungen dieser Erfindung bestehen insbesondere darin, daß diese technische Lehre an keine Rastermaße gebunden ist. Infolge der Anordnung zweier Schläuche in einem nahezu gemeinsamen Raum, hier zwischen den beiden Gurttaschen, ergibt sich in diesem Gesamtsystem ein Druckausgleich, wegen Druck und Gegendruck, wodurch sich die Stabilität dieses Gesamtsystems erhöht, insbesondere die Knickstabilität eines luftgefüllten Schlauches bei Biegung. Auf die gleiche Ursache ist die positive Wirkung zurückzuführen, daß bei Erhöhung der Spannweite der temporären Überdachung der Innen- bzw. Betriebsdruck nicht erhöht zu werden braucht. Desweiteren erhöht sich die Einsatz-/Betriebsicherheit, da bei Druckausfall in einem der beiden und somit zusammenwirkenden Schläuche der andere nichtdefekte Schlauch die Funktion, wenn auch etwas eingeschränkt, doch aber weiterhin aufrecht erhält. Auch wären damit in der Sanierung von Spezialbauten (Großtanks, Kläranlagen, Kühltürme usw.) längerfristig haltende Schutzdächer mit größereren Spannweiten möglich, da jede geometrische Form der Überdachungen konfektioniert werden kann. Die Doppelkammertragelemente übernehmen bei dieser Alternative die Funktion einer sogenannten "Verlorenen Schalung" und können später in die tragende Dachkonstruktion mit einbezogen werden.
Eine weitere Alternative zur Lösung der vorgenannten Aufgabe der Erfindung besteht darin, daß statt Planen, textile Flächengebilde mit netzartiger Struktur zwischen die mittels Überdruck aufgeblasenen Doppelkammertragelemente eingenäht, verschweißt oder anderweitig befestigt werden. Die netzartigen textilen Flächengebilde werden mit einem schnell ausreagierenden leichten und recycelbaren Kunststoffschaum besprüht. Nach dem Abbinden des Kunststoffschaumes entsteht ein leichtes, wärmedämmendes Dachgebildefür eine mittelfristige temporäre Überdachung, welche nach Ablauf der Überdachungsfunktion wieder geshreddert und/oder eingeschmolzen werden kann. Im technologischen Ablauf für Spezialbauten könnte dieses Kunststoffschaumgebilde als Künftige Isolierung für den Baukörper mit einbezogen werden.
Another special embodiment of this technical teaching is to be seen in the fact that an exchange of the gaseous medium in the cavities of the pressure hoses by a rapidly reacting plastic foam is provided. After the cavities have been filled with the gaseous medium, this can be achieved by refilling the foam and displacing the gaseous medium.
As a further alternative, a combination of double-chamber elements which are filled with gaseous medium and those which are filled with plastic foam is also possible, and this also with different dimensions. In this way, the execution of the supporting scaffold arrangement can be adapted in some areas to the respective structural requirements in the respective area of the overall construction.
When creating this temporary protective roofing, this roofing tarpaulin with its double-chamber supporting elements on both sides and spanning the building is made in a known manner on a scaffold erected on the structure at its upper limit or on a base frame to be produced from scaffolding tubes by means of conventional fastening elements and by means of tension belts and the eyelets located in the roofing tarpaulin attached. The pressure hoses in this flexible supporting frame are then filled with compressed air, causing the roof to bulge and a protective roof to be formed; if necessary, the gaseous medium is replaced by rapidly reacting plastic foam.
The advantageous effects of this invention are, in particular, that this technical teaching is not tied to any grid dimensions. As a result of the arrangement of two hoses in an almost common space, here between the two belt pockets, there is pressure compensation in this overall system due to pressure and back pressure, which increases the stability of this overall system, in particular the kink stability of an air-filled hose when it bends. The positive effect can be attributed to the same cause, that when the span of the temporary roofing is increased, the internal or operating pressure need not be increased. Furthermore, operational and operational safety is increased, because if there is a pressure loss in one of the two and thus interacting hoses, the other non-defective hose will continue to function, albeit somewhat restrictedly. This would also make long-term protective roofs with larger spans possible in the renovation of special buildings (large tanks, sewage treatment plants, cooling towers, etc.), since any geometric shape of the roofs can be assembled. With this alternative, the double-chamber support elements take on the function of a so-called "lost formwork" and can later be incorporated into the load-bearing roof structure.
Another alternative to achieving the aforementioned object of the invention is that, instead of tarpaulins, textile fabrics with a net-like structure are sewn, welded or otherwise fastened between the double-chamber support elements which are inflated by overpressure. The mesh-like textile fabrics are sprayed with a rapidly reacting, light and recyclable plastic foam. After the plastic foam has set, a light, heat-insulating roof structure is created for a medium-term temporary roofing, which can be shredded and / or melted again after the roofing function has expired. In the technological process for special buildings, this plastic foam structure could be included as future insulation for the building structure.

An einem Ausführungsbeispiel wird die Erfindung im folgendem näher erläutert.The invention will be explained in more detail below using an exemplary embodiment explained.

An der Oberkante eines Gerüstes 1, welches das Bauwerk umgibt, ist mittels Spanngurte 3 und weiterer üblicher und geeigneter Spannelemente vermittels der Ösen 4 einer Überdachungsplane 5 diese beidseitig und das Bauwerk übergreifend befestigt. Auf dieser Überdachungsplane 5 sind mit Überdruck gegenüber dem athmosphärischen Druck ausgestattete Doppelkammertragelemente 6, 6', zweifach mit ellipsenförmigem Querschnitt, der durch jeweils einen auf der Innenseite und einen auf der Außenseite der Überdachungsplane 5 in die Doppelkammertragelemente 6 eingefügten Druckschlauch 7 erzeugt ist, angeordnet. Die Druckschläuche besitzen in vorbekannter Art und Weise Füll-, Ablaß- sowie Sicherheitsventile. Die Doppelkammertragelemente 6 erstrecken sich bogenüberspannend von der einen Seite des zu überdachenden Bauwerkes von deren Befestigungselemente 2, 3, 4 hin zur anderen Seite des Bauwerkes bis zu deren Befestigungselemente 2, 3, 4. Gleiche Doppelkammertragelemente 6' sind auch auf der Überdachungsplane 5 jeweils zwischen den Bögen 6 parallel zur Befestigung 2, 3, 4 in einem Abstand A voneinander angeordnet. Die Doppelkammertragelement-Anordnungen 6 und 6' sind in ihrer ellipsenförmigen Gestalt dadurch gebildet, daß paarweise, somit auf jeder Seite der Überdachungsplane 5, eine Gurttasche 8 auf der Planenoberfläche 5, innen und am gleichen Ort gegenüberliegend außen, angebracht ist, in der jeweils ein Druckschlauch 7, nicht dauerhaft befestigt, eingelegt ist. Der Druckschlauch 7 besitzt einen Umfang, der etwa der Erstreckung aus dem Bogen B" plus Strecke B, entspricht. Die Gurttasche 8 ist aus einem Band gebildet, welches an seinen beiden Seiten 8' fest und dauerhaft mit der Überdachungsplane 5 durch Nähen verbunden ist wobei der Mittelbereich 8" (Bogen) der Gurttasche 8 eine größere Ausdehnung besitzt, als der innere Abstand B zwischen den beiden Befestigungsstreifen 8' der Gurttasche 8 auf der Überdachungsplane 5 aufweist, wodurch sich zwei Hohlräume 9 beidseits der Überdachungsplane 5 in bogenförmiger Ausdehnung 8" bilden und, paarweise gesehen, damit eine ellipsenförmige Aufwölbung beider Gurttaschen 8 beidseits der Überdachungsplane 5 und damit des hierdurch gebildeten Doppelkammertragelementes 6 bei Druckbeaufschlagung der in die Gurttaschen 8 eingefügten Druckschläuche 7 gegeben ist. Als weitere vorteilhafte Ausgestaltung kann den Gurttaschen 8 in ihrem Innern auf der Fläche der Überdachungsplane 5 jeweils eine Beilage 10 zur weiteren Stabilisierung der erfindungsgemäßen Doppelkammertragelemente 6 und 6' beigeordnet sein.
Verfahrensgemäß wird zur Erstellung dieser temporären Schutzüberdachung auf einem in vorbekannter Art und Weise am Bauwerk errichteten Gerüst 1 an seiner oberen Begrenzung mittels herkömmlicher Befestigungselemente sowie mittels Spanngurte 3 und den in der Überdachungsplane 5 befindlichen Ösen 4 diese Überdachungsplane 5 mit ihren Doppelkammertragelementen 6, 6' beidseitig am Gerüst sowie das Bauwerk überspannend befestigt und danach die Druckschläuche 7 im Traggerüst, bestehend aus den Doppelkammertragelementen 6, 6' mit späteren ellipsenförmigem Querschnitt, mit Druckluft befüllt, wodurch sich die Überdachung aufwölbt und ein Schutzdach ausbildet.
Vorteilhafterweise kann die Überdachungsplane 5 aus lichtdurchlässigem Material bestehen, wodurch die bisherigen zusätzlichen Ausleuchtmaßnahmen entfallen können. Am einfachsten sollten die Doppelkammertragelemente linear und parallel angeordnet sein, jedoch sind auch andere Anordnungen denkbar, so z.B. eine kreuzförmige Anordnung auf der Überdachungsplane. Hierbei müßten dann die einzelnen Schläuche mit Verteilerstücken verbunden sein, welche beispielsweise in die Plane eingebunden sein könnten. Sollte der Fall eintreten, daß Planen zu verknüpfen sind, wobei ja dann auch die Schläuche zu verknüpfen sind, müssen die Schläuche überstehend angeordnet sein und ein stabiles Metallgestell müßte dann die Stabilität für die Verbindung erstellen. Dabei könnten zwei Stäbe über und zwei Stäbe unter der Plane als Führungslinie angeordnet sein. Mit dieser erfindungsgemäßen Lehre kann in kürzester Frist ein Schutzdach mit flexibler Spannweite kostengünstig errichtet werden, welches auch keine besonderen Anforderungen an die Aufstellfläche erforderlich macht. Durch die beschriebene Anordnung der Schläuche wird eine hohe Stabilität des textilen Bauwerkes erreicht, da ein Abknicken der Schläuche nicht mehr gegeben ist. Durch den Einsatz von Doppelkammertragelementen verschiedener Größen, damit von Schläuchen mit unterschiedlichen Durchmessern ist die v.g. Flexibilität in der Spannweite möglich. Planungsphasen können schneller, insbesondere aber kann der Bauablauf wesentlich effektiver und ganzjährig erfolgen. Beim Einsatz dieser flexiblen Überdachung im Bauhaupt- und - nebengewerbe, im Korrosionsschutz und in der Betonsanierung kann auf Grund der Wetterunabhängigkeit der Arbeitszeitausfall wesentlich minimiert werden. Ebenso ist davon auszugehen, daß sich die Anzahl der wetterbedingten Kündigungen für gewerbliche Arbeitnehmer reduzieren läßt. Weiterhin ist die vorgeschlagene technische Lösung in ihrem Äquivalenzbereich gut ausgestalltbar sowie auch für andere Anwendungsbereiche nutzbar, so z.B. als Abdeckungen für Baugruben, Zelte für Materiallagerungen, für.den Katastrophenschutz oder für Veranstaltungen jeglicher Art.
On the upper edge of a scaffold 1, which surrounds the building, is attached by means of lashing straps 3 and other usual and suitable tensioning elements by means of the eyelets 4 of a roof tarpaulin 5 on both sides and across the building. On this roof tarpaulin 5, double-chamber support elements 6, 6 'equipped with overpressure compared to the atmospheric pressure are arranged, twice with an elliptical cross-section, which is generated by a pressure hose 7 inserted into the double-chamber support elements 6 on the inside and one on the outside of the roof tarpaulin 5. The pressure hoses have filling, drainage and safety valves in a known manner. The double-chamber support elements 6 extend across the arch from one side of the building to be roofed from their fastening elements 2, 3, 4 to the other side of the building to their fastening elements 2, 3, 4. The same double-chamber support elements 6 'are also on the roofing tarpaulin 5 between each the arches 6 parallel to the attachment 2, 3, 4 at a distance A from each other. The double-chamber support element arrangements 6 and 6 'are formed in their elliptical shape by pairs, thus on each side of the roof tarpaulin 5, a belt pocket 8 is attached to the tarpaulin surface 5, inside and at the same location opposite, in each of which Pressure hose 7, not permanently attached, is inserted. The pressure hose 7 has a circumference which corresponds approximately to the extension from the arch B ″ plus the distance B. The belt pocket 8 is formed from a band which is firmly and permanently connected to the roof tarpaulin 5 by sewing on both sides 8 ′ the central region 8 "(arch) of the belt pocket 8 has a greater extent than the inner distance B between the two fastening strips 8 'of the belt pocket 8 on the roofing tarpaulin 5, as a result of which two cavities 9 are formed on both sides of the roofing tarpaulin 5 in an arcuate dimension 8" and, seen in pairs, so that there is an elliptical bulge of both belt pockets 8 on both sides of the roof tarpaulin 5 and thus the double chamber support element 6 formed thereby when pressure is applied to the pressure hoses 7 inserted into the belt pockets 8. As a further advantageous embodiment, the belt pockets 8 can be arranged on the surface inside the roof tarpaulin 5 each has a supplement 10 for further stabilization of the double-chamber support elements 6 and 6 'according to the invention.
According to the method, to create this temporary protective roof on a scaffold 1 constructed in a known manner on the building at its upper limit by means of conventional fastening elements and by means of tension belts 3 and the eyelets 4 located in the roof tarpaulin 5, this roof tarpaulin 5 with its double-chamber support elements 6, 6 'on both sides attached to the scaffolding and the structure, and then the pressure hoses 7 in the support frame, consisting of the double-chamber support elements 6, 6 'with later elliptical cross section, are filled with compressed air, causing the roof to bulge and a protective roof to be formed.
Advantageously, the covering tarpaulin 5 can be made of translucent material, so that the previous additional lighting measures can be dispensed with. The simplest way should be to arrange the double-chamber support elements linearly and in parallel, but other arrangements are also conceivable, for example a cross-shaped arrangement on the roofing tarpaulin. The individual hoses would then have to be connected to distributor pieces, which could be integrated into the tarpaulin, for example. If the case arises that tarpaulins have to be connected, and then the hoses have to be connected as well, the hoses must be arranged so that they protrude and a stable metal frame would then have to create the stability for the connection. Two bars above and two bars below the tarpaulin could be arranged as a guideline. With this teaching according to the invention, a canopy with a flexible span can be erected cost-effectively in the shortest possible time, which also does not make any special demands on the installation area necessary. Due to the arrangement of the hoses described, a high stability of the textile structure is achieved since the hoses are no longer kinked. The use of double-chamber support elements of different sizes, and thus of hoses with different diameters, enables the above-mentioned flexibility in the span. Planning phases can be faster, but in particular the construction process can be carried out much more effectively and all year round. When using this flexible roofing in the main and secondary construction, corrosion protection and concrete renovation, the loss of working hours can be significantly minimized due to the weather independence. It can also be assumed that the number of weather-related layoffs for commercial workers can be reduced. Furthermore, the proposed technical solution in its equivalence area can be easily equipped and also used for other areas of application, for example as covers for construction pits, tents for material storage, for civil protection or for events of any kind.
