Description

Die Erfindung betrifft ein Membran-Wandelement für die Errichtung einer Zelt- oder Hallenkonstruktion, mit zumindest zwei Wandmembranen und Einspannelementen, wobei die zumindest zwei Wandmembranen an gegenüberliegenden Endabschnitten mittels der Einspannelemente spannbar und durch zumindest ein starres Abstandselement so voneinander beabstandbar sind, daß sich zwischen den zumindest zwei Wandmembranen ein Hohlraum ausbildet.The invention relates to a membrane wall element for the construction of a tent or hall construction, with at least two wall membranes and clamping elements, wherein the at least two wall membranes are clamped at opposite end portions by means of the clamping elements and spaced apart by at least one rigid spacer so that between the at least two wall membranes forms a cavity.

Humanitäre Hilfsorganisationen und militärische Verbände nehmen oft an diversen Missionen teil, bei denen es notwendig ist, Personen in kurzfristig zu errichtenden Unterkünften unterzubringen. In diesem Zusammenhang werden üblicherweise auf Zelten basierende Lösungen angewendet, aber auch Containerlösungen wurden ausprobiert. Vom wirtschaftlichen und transportmäßigen Standpunkt aus gesehen, erweist sich die Zeltvariante als die günstigste Lösung, diese bereitet aber hinsichtlich der thermischen Eigenschaften Probleme, weshalb von verschiedenen Seiten eine Verbesserung dieser Eigenschaften angestrebt wird. Dies sowohl um thermische Signale zu reduzieren als auch Energie unter kalten und warmen klimatischen Verhältnissen einzusparen.Humanitarian aid organizations and military organizations often participate in various missions where it is necessary to accommodate people in short-term accommodation. In this context, solutions based on tents are usually used, but also container solutions have been tried. From the economic and transport point of view, the tent variant proves to be the cheapest solution, but this is in terms of thermal properties problems, which is why from different sides, an improvement of these properties is sought. This both to reduce thermal signals and save energy in cold and warm climates.

Aus anderen Anwendungen ist es bereits bekannt, Luft als Isolationsmedium einzusetzen, während dies für konventionelle Zelt- oder Hallenkonstruktionen bisher noch nicht geschah.From other applications, it is already known to use air as an insulating medium, while this was not yet done for conventional tent or hall constructions.

Zwar sind mehr oder weniger permanente Hallenkonstruktionen aus Zeltleinwand bekannt, bei denen die Hallen u.a. durch Luft aufrecht erhalten werden, die sich im Überdruck zwischen den Stoffbahnen befindet. Eine solche Lösung würde sich jedoch nicht für die oben erwähnten Zelt- oder Hallenkonstruktionen eignen, da sie unter anderem viel Zusatzausrüstung verlangt, die noch dazu in einer sicheren und stabilen Art und Weise betrieben werden müßte.Although more or less permanent hall constructions of tent canvas are known in which the halls are maintained, inter alia, by air, which is located in the overpressure between the panels. However, such a solution would not be suitable for the above-mentioned tent or hall constructions, as it requires, inter alia, a lot of additional equipment, which would also have to be operated in a safe and stable manner.

Aus der EP 1 273 743 A geht ein Zelt mit einer pneumatischen Wandkonstruktion hervor, die eine zweischichtige, aus drei flexiblen Zeltbahnen gebildete Wandstruktur aufweist. Die innere Schicht, die von der inneren und der mittleren Zeltbahn begrenzt sind, ist aufblasbar und bildet die Haupttragstruktur der Wandkonstruktion, während die äußere Schicht, die von der mittleren und der äußeren Zeltbahn begrenzt ist, einen Konvektionsraum darstellt, der von der Umgebungsluft in aufsteigender Richtung durchströmbar ist. Zwischen der mittleren und der äußeren Zeltbahn sind weiters aufblasbare Stützschläuche als zusätzliche Tragestruktur und als Abstandshalter vorhanden. Ein derartiges Zelt erfordert jedoch aufgrund der ständigen Druckbeaufschlagung einen relativ hohen Aufwand und kann ohne Stromversorgung durch einen Netzanschluß oder einen Generator nicht betrieben werden.From the EP 1 273 743 A A tent with a pneumatic wall construction emerges, which has a two-layered wall structure made up of three flexible tarpaulins. The inner layer bounded by the inner and the middle tarpaulin is inflatable and forms the main supporting structure of the wall structure, while the outer layer delimited by the middle and outer tarpaulin constitutes a convection space rising from the ambient air Direction can be flowed through. Between the middle and the outer tarpaulin further inflatable support tubes are available as an additional support structure and as a spacer. However, such a tent requires due to the constant pressurization a relatively high cost and can not be operated without power supply through a power supply or a generator.

In der EP 0 596 807 A ist ein Wandelement für ein Zelt angegeben, das durch einen Rahmen und eine darauf gespannte zweiflächige Membran gebildet ist. Der Rahmen ist durch eine Spannkonstruktion zwischen einem Montage- und einem Spannungszustand bewegbar und wird von der Membran umhüllt. Im Spannungszustand des Rahmens spannt dieser die zweiflächige Membran, wobei zwei einander gegenüberliegende Rahmenteile aus Vierkanthohlprofilen bestehen, welche zugleich als Abstandshalter zwischen den Membranflächen dienen. Jedes wandelement enthält jeweils einen vollständigen Rahmen und die Membranen sind außen um die Rahmenteile geführt. Benachbarte Wandelemente stoßen mit den außen um die Rahmen verlaufenden Membranen aneinander.In the EP 0 596 807 A is a wall element for a tent indicated, which is formed by a frame and a stretched two-sided membrane. The frame is movable by a clamping structure between a mounting and a tension state and is enveloped by the membrane. In the state of tension of the frame of this biases the dihedral membrane, with two opposing frame members made of square hollow sections, which also serve as spacers between the membrane surfaces. Each wall element contains in each case a complete frame and the membranes are guided outside around the frame parts. Adjacent wall elements abut each other with the membranes extending around the outside of the frames.

Bei der aus Wandelementen zusammengesetzten Gartenbeet-Abdeckung der FR 1 548 635 A bestehen die einzelnen Wandelemente aus starren Rahmen, welche von einem Folienschlauch umhüllt sind. Das Spannen des Folienschlauches wird ohne Spannelemente erreicht, indem der entsprechend groß dimensionierte Rahmen in diesen eingeschoben wird.When assembled from wall elements garden bed cover the FR 1 548 635 A the individual wall elements consist of rigid frames, which are enveloped by a film tube. The tensioning of the film tube is achieved without clamping elements by the correspondingly large-sized frame is inserted into this.

Die in der DE 33 20 212 A angegebene Folienbefestigung ermöglicht durch das Vorsehen eines Hohlprofilelements das Einspannen von zwei benachbarten Wandelementen durch ein Hohlprofilelement und somit eine Übergangsdichtung zwischen den-beiden, die Beabstandung der Foliendoppelwand geschieht durch eine in das Hohlprofilelement eingeschobene Profilleiste.The in the DE 33 20 212 A specified film attachment allows by providing a hollow profile element the clamping of two adjacent wall elements by a hollow profile element and thus a transitional seal between the two, the spacing of the film double wall is done by an inserted into the hollow profile element profile strip.

Dieses Prinzip wird ebenso für die Spannschienenkonstruktion der DE 33 10 895 A und für die Wandelemente gemäß EP 0 021 834 A angewandt.This principle is also true for the tensioning rail construction of the DE 33 10 895 A and for the wall elements according to EP 0 021 834 A applied.

Aufgabe der Erfindung ist es, ein Wandelement der eingangs genannten Art zu schaffen, welches trotz einfacher Konstruktion und ohne Druckluftbeaufschlagung sehr gute thermische Eigenschaften aufweist. Weitere Aufgabe der Erfindung ist es, ein Wandelement anzugeben, das bei hoher Wärmedämmung auch Dichtheit gegen Gase und Flüssigkeiten aufweist.The object of the invention is to provide a wall element of the type mentioned, which has very good thermal properties despite simple design and without compressed air. Another object of the invention is to provide a wall element, which also has tightness against gases and liquids with high thermal insulation.

Erfindungsgemäß wird dies dadurch gelöst, daß das zumindest eine starre Abstandselement von den Einspannelementen separiert angeordnet und an gegenüberliegenden Innenseiten der zumindest zwei Wandmembranen gelenkig mit diesen verbunden ist, sodaß sich das Abstandselement im gespannten Zustand der zumindest zwei Wandmembranen durch die auf diese ausgeübte Spannung so einstellt, daß die zumindest zwei Wandmembranen voneinander beabstandet gehalten sind.According to the invention, this is achieved in that the at least one rigid spacer element is arranged separated from the clamping elements and hingedly connected to opposite inner sides of the at least two wall membranes, so that adjusts the spacer element in the tensioned state of at least two wall membranes by the voltage applied to this in that the at least two wall membranes are kept at a distance from each other.

Bedingt durch die auf die Wandmembranen ausgeübte Spannung stellt sich das zumindest eine Abstandselement so ein, daß es die Wandmembranen beabstandet hält, wodurch ein thermisch Isolierender Luftpolster gebildet wird.Due to the tension exerted on the wall membranes, the at least one spacer element adjusts to keep the wall membranes spaced, thereby forming a thermally insulating air cushion.

Die zumindest zwei Wandmembranen können dabei aus Zeltleinwand aber auch aus jedem anderen geeigneten Material gebildet sein.The at least two wall membranes can be formed of tent canvas but also of any other suitable material.

Eine stabile Einspannung der Wandmembranen kann dadurch erreicht werden, daß die zumindest zwei Wandmembranen an zwei gegenüberliegenden Endabschnitten in Einspannelementen festgelegt sind, die in bevorzugter Weise durch Profilstäbe --gebildet sind, welche eine hohe Steifigkeit bei niedrigem Gewicht aufweisen und zugleich geeignete Nuten für eine Einspannung der Wandmembranen aufweisen können.A stable clamping of the wall membranes can be achieved in that the at least two wall membranes are fixed at two opposite end portions in clamping elements, which are formed in a preferred manner by profiled bars - which have a high rigidity at low weight and at the same time suitable grooves for a clamping may have the wall membranes.

Um die zumindest zwei Wandmembranen möglichst gleichmäßig gemeinsam einspannen zu können, hat es sich als vorteilhaft herausgestellt, wenn die zumindest zwei Wandmembranen an gegenüberliegenden Endabschnitten jeweils zusammengefügt sind.In order to clamp the at least two wall membranes as evenly as possible together, it has been found to be advantageous if the at least two wall membranes are joined together at opposite end portions.

Dabei kann eine bekannte, zuverlässige Einspannhilfe verwendet werden, indem an den zusammengefügten Endabschnitten der Wandmembranen randseitig eine Kederschnur vorgesehen ist, über welche die Einspannung der Wandmembranen vorgenommen werden kann.In this case, a known, reliable gripping aid can be used by a beading cord is provided on the joined end portions of the wall membranes edge, on which the clamping of the wall membranes can be made.

Entsprechend können die Profilstäbe hinterschnittene Längskanäle aufweisen, in welche die Kederschnüre der zusammengefügten Wandmembranen einziehbar sind. Damit können die Wandmembranen entlang ihren zur Einspannung vorgesehenen Endabschnitten in den Profilstäben beim Einspannvorgang gegen ein Herausgleiten gesichert werden.Accordingly, the profile bars may have undercut longitudinal channels, in which the Kederschnüre the assembled wall membranes are retractable. Thus, the wall membranes can be secured along their intended for clamping end portions in the profile bars during clamping against slipping out.

Um ein arbeitsaufwendiges Einziehen der Kederschnüre zu vermeiden, können die Profilstäbe gemäß einer weiteren Ausführungsform der Erfindung Deckschienen und Längskanäle, in die die Kederschnüre der zusammengefügten Wandmembranen einlegbar sind, aufweisen, und die Längskanäle können mittels der Deckschienen so verschließbar sein, daß die Kederschnüre in den Profilstäben fixiert sind.In order to avoid a laborious pulling the Kederschnüre, the profile bars according to another embodiment of the invention, cover rails and longitudinal channels into which the Kederschnüre the assembled wall membranes can be inserted, and the longitudinal channels can be closed by means of the cover rails so that the Kederschnüre in the Profile bars are fixed.

Als eines der möglichen Spannmittel zum Spannen der Wandmembranen kann zwischen den Profilstäben eine Spannvorrichtung mit Spannstäben vorgesehen sein, über welche die in den Profilstäben festgelegten Wandmembranen auseinanderspannbar sind. Die von der Spannvorrichtung auf die Spannstäbe ausgeübten Kräfte bewegen -die Profilstäbe derartig, daß die -in den Profilstäben eingespannterrWandmembranen in eine-gespannte Stellung gebracht werdenAs one of the possible clamping means for tensioning the wall membranes may be provided between the profile bars, a tensioning device with tension rods, over which the fixed in the profile bars wall membranes are spread apart. The forces exerted by the tensioning device on the tension rods move the profile rods in such a way that the wall diaphragms clamped in the profile rods are brought into a tensioned position

Eine mögliche Weiterbildung der Erfindung kann darin bestehen, daß die . Spannvorrichtung über eine Kniehebelvorrichtung betätigbar ist, deren Antriebsspindel zur Betätigung zweier Kniehebel quer zur Längsachse der Spannstäbe orientiert Ist. Durch Drehbewegen der Antriebsspindel mittels eines dafür geeigneten Werkzeugs kann eine Spannbewegung der Spannstäbe bewirkt werden, die das Aufspannen der-Wandmembranen und das dadurch hervorgerufene Distanzieren derselben aufgrund des in die Abstandsstellung gebrachten Abstandselements zur Folge hat.A possible development of the invention may consist in that the. Clamping device can be actuated by a toggle device whose drive spindle is oriented transversely to the longitudinal axis of the tension rods for actuating two toggle levers. By rotating the drive spindle by means of a tool suitable for this purpose, a tensioning movement of the tensioning rods can be effected which results in the clamping of the wall diaphragms and the distancing caused thereby due to the spacing element brought into the spacing position.

Eine weitere Ausführungsform der Erfindung kann darin bestehen, daß die Spannstäbe ein Hohlprofil aufweisen; mit dem sie an einem Ende auf Profileriden der Kniehebelvorrichtung aufschiebbar sind, sodaß die Spannstäbe über durch die Kniehebel betätigte Verschiebeelemente bewegbar sind, und daß an das andere Ende der Spannstäbe ein Flanschstück zur Fixierung an den Profilstäben angebracht ist. Auf diese Weise lassen sich über die Kniehebelvorrichtung relativ hohe Kräfte zum Aufspannen der Wandmembranen aufbringen, sodaß auch größere erfindungsgemäße Membran-Wandelemente in den gespannten Zustand übergeführt und in diesem gehalten werden können.A further embodiment of the invention may consist in that the tension rods have a hollow profile; with which they are pushed at one end on Profileriden the toggle device, so that the clamping rods are moved by actuated by the toggle lever displacement elements, and that is attached to the other end of the clamping rods a flange piece for fixing to the profile bars. In this way, relatively high forces can be applied via the knee lever device for clamping the wall membranes, so that larger membrane wall elements according to the invention can also be transferred into the tensioned state and held therein.

Eine gleichmäßige Beabstandung der Wandmembranen läßt sich dadurch erreichen, daß die Längsseiten des zumindest einen starren Abstandselements zwischen den zumindest zwei Wandmembranen parallel zu den einander gegenüberliegenden Zusammenfügungslinien der Wandmembranen verlaufen.A uniform spacing of the wall membranes can be achieved in that the longitudinal sides of the at least one rigid spacer element between the at least two wall membranes extend parallel to the mutually opposite joining lines of the wall membranes.

Eine mögliche Variante der Erfindung kann darin bestehen, daß das zumindest eine starre Abstandselement ein starres Zwischenstück aufweist, an dessen Längsseiten flexible Streifen angeformt sind, die mit den gegenüberliegenden Innenseiten der zumindest zwei Wandmembranen- verbunden -sind, sodaß- die Längsseiten des zumindest einen starren Zwischenstücks-gelenkig -mit --den--Wandmembranen verbunden sind, wobei die Anlenkungsstellen an den Wandmembranen jeweils gleich weit von den Rändern der Endabschnitte der Wandmembranen beabstandet sind, und wobei das starre Zwischenstück und die zu den Endabschnitten verlaufenden Membranteile im gespannten Zustand - im Querschnitt gesehen - ein gleichschenkeliges Dreieck ausbilden.A possible variant of the invention may consist in that the at least one rigid spacer element has a rigid intermediate piece, on the longitudinal sides of flexible strips are formed, which are connected to the opposite inner sides of the at least two Wandmembranen-sinds, so that the longitudinal sides of the at least one rigid Intermediate articulated -mit-den - wall - membranes are connected, wherein the articulation points on the wall membranes each equidistant from the edges of the end portions of the wall membranes, and wherein the rigid intermediate piece and extending to the end portions membrane parts in the tensioned state - im Seen cross-section - form an isosceles triangle.

Werden solche Zwischenstücke an gegenüberliegenden Endbereichen zwischen zwei Wandmembranen angebracht, so ermöglichen sie im ungespannten Zustand der Wandmembranen ein Lagern derselben ohne Zwischenabstand. Sobald die Wandmembranen in den gespannten Zustand übergeführt werden, stellen sich die starren Zwischenstücke aufgrund der auf sie wirkenden Kräfte quer zu den Wandmembranen ein und stellen somit eine Beabstandung derselben und die Ausbildung eines Lufthohlraumes zwischen diesen sicher.If such intermediate pieces are attached to opposite end regions between two wall membranes, then they permit the same in the untensioned state of the wall membranes without spacing therebetween. As soon as the wall membranes are brought into the tensioned state, the rigid intermediate pieces, due to the forces acting on them, set transversely to the wall membranes and thus ensure a spacing thereof and the formation of an air cavity between them.

Daher kann weiters vorgesehen sein, daß das zumindest eine starre Zwischen stück eine vorbestimmbare Steifigkeit aufweist, um die Trennung der voneinander beabstandeten Wandmembranen zu erzielen, wenn die Wandmembranen eingespannt sind.Therefore, it may further be provided that the at least one rigid intermediate piece has a predeterminable stiffness in order to achieve the separation of the spaced-apart wall membranes when the wall membranes are clamped.

Das starre Zwischenstück wird zweckmäßig in Stabform ausgeführt sein, es kann aber jede andere einen Abstand erzielende Ausführungsform im Rahmen der Erfindung gewählt werden.The rigid intermediate piece will be carried out expediently in rod form, but it may be any other distance-achieving embodiment can be selected within the scope of the invention.

Um die auf die einander gegenüberliegenden Membranen wirkenden Zugkräfte dazu zu benutzen, das starre Zwischenstück quer zu diesen auszurichten, sobald eine Zugspannung auf diese ausgeübt wird, werden die flexiblen Streifen so angebracht, daß sie sich in entgegengesetzten Richtungen von den Längsseiten des starren Zwischenstücks wegerstrecken.To the acting on the opposite membranes tensile forces to do so to use to align the rigid spacer transversely thereto when a tensile stress is applied thereto, the flexible strips are mounted so that they extend in opposite directions from the longitudinal sides of the rigid intermediate piece.

Grundsätzlieh können im Rahmen der Erfindung zwei oder mehrere Wandmembranen kombiniert werden, eine konstruktiv einfache Ausführungsform der Erfindung besteht darin, daß zwei Wandmembranen ausgebildet sind, die im gespannten Zustand durch zwei Abstandselemente voneinander beabstandet gehalten werden.In principle, two or more wall membranes can be combined in the context of the invention, a structurally simple embodiment of the invention is that two wall membranes are formed, which are held spaced apart by two spacer elements in the tensioned state.

Eine Abdichtung der erfindungsgemäßen Wandelemente läßt sich erzielen, indem die Wandmembranen in abgedichteter Form in den Teilen, die sich entlang sämtlicher Membranendbereiche erstrecken, miteinander verbunden sind, und Lüftungsvorrichtungen vorhanden sind, damit Luft in die Hohlräume eindringen kann, wenn das Wandelement aufgespannt wird.Sealing of the wall elements according to the invention can be achieved by connecting the wall membranes in sealed form in the parts that extend along all the membrane end regions, and with ventilation devices to allow air to enter the cavities when the wall element is clamped.

Ein erfindungsgemäßes Wandelement mit drei Wandmenbranen kann dadurch ausgebildet werden, daß eine Innenwandmembran und eine Außenwandmembran vorgesehen sind, zwischen denen eine Zwischenwandmembran verläuft, wobei die Innenwandmembran, die Zwischenwandmembran und die Außenwandmembran im eingespannten Zustand durch zumindest zwei starre Abstandselemente so voneinander beabstandet sind, daß sich zwischen diesen Hohlräume ausbilden.An inventive wall element with three Wandmenbranen can be formed in that an inner wall membrane and an outer wall membrane are provided, between which an intermediate wall membrane, wherein the inner wall membrane, the partition wall membrane and the outer wall membrane in the clamped state by at least two rigid spacers are spaced from each other so that form between these cavities.

Die Beabstandung eines solchen Wandelements mit drei Wandmembranen ist aufwendiger als jene bei einem aus zwei Membranen gebildeten Wandelement. Eine mögliche Ausführungsform kann darin bestehen, daß die starren Abstandselemente starre Zwischenstücke aufweisen, an deren Längsseiten flexible Streifen angeformt sind, die mit den gegenüberliegenden Innenseiten der Innenwandmembran und der Zwischenwandmembran sowie der Zwischenwandmembran und der Außenwandmembran verbunden sind, sodaß die Längsseiten der starren Zwischenstücke gelenkig mit den Wandmembranen verbunden sind, wobei die Anlenkungsstellen an den Wandmembranen so gewählt sind, daß die zu den Endabschnitten verlaufenden Membranteile der Innen- und der Außenwandmembran und die starren Zwischenstücke im gespannten Zustand - im Querschnitt-gesehen - ein gleichsehenkeliges Dreieck ausbilden, während die Zwischenwandmembran entlang der Höhenlinie des gleichschenkeligen Dreiecks durchgehend eben verläuft. Somit stellen sich die zwischen den Wandmembranen angeordneten Zwischenstücke beim Spannen des Dreiwandmembran-Wandelements so ein, daß alle drei Wandmembranen gleichmäßig voneinander beabstandet sind, sodaß sich zwei voneinander getrennte, benachbarte Lufthohlräume ausbilden, die eine noch höhere Wärmedämmung als das Zweiwandmembran-Wandelement ermöglichen.The spacing of such a wall element with three wall membranes is more complicated than that in a wall element formed from two membranes. A possible embodiment may consist in that the rigid spacer elements have rigid intermediate pieces, on the longitudinal sides of flexible strips are formed, which are connected to the opposite inner sides of the inner wall membrane and the diaphragm diaphragm and the diaphragm diaphragm and the Outside wall membrane are connected so that the longitudinal sides of the rigid intermediate pieces are pivotally connected to the wall membranes, wherein the Anlenkungsstellen are selected on the wall membranes so that the extending to the end portions membrane parts of the inner and the outer wall membrane and the rigid intermediate pieces in the tensioned state - in cross section -see - form a gleicheschlkeliges triangle, while the diaphragm wall along the contour line of the isosceles triangle is consistently flat. Thus, when the three-wall membrane wall member is tensioned, the intermediate pieces arranged between the wall membranes adjust so that all three wall membranes are evenly spaced so as to form two separate, adjacent air cavities enabling even greater thermal insulation than the two-wall membrane wall element.

Für den militärischen Einsatz können die Wandmembranen aus einem Material hergestellt sein, das gegen Kampfgase o.ä. dicht ist.For military use, the wall membranes can be made of a material that can be used against combat gases or the like. is tight.

Weiters kann vorgesehen sein, daß die Zwischenwandmembran mit Aluminium oder einem anderen geeigneten Material beschichtet ist, um eine Wärmereflexion und/oder eventuell auch eine Abschirmung gegen elektromagnetische Strahlung zu erreichen. Die übrigen Wandmembranen können ebenfalls mit einer derartigen Beschichtung versehen sein.Furthermore, it can be provided that the partition wall membrane is coated with aluminum or other suitable material in order to achieve a heat reflection and / or possibly also a shield against electromagnetic radiation. The remaining wall membranes may also be provided with such a coating.

Die Wandmembranen können ferner so ausgeprägt sein, daß eine Lichtdurchlässigkeit unterbunden wird.The wall membranes may also be so pronounced that a light transmission is prevented.

Um eine einfache Beseitigung von Verunreinigungen zu ermöglichen, kann die Innenwandmembran aus einem leicht zu reinigenden Material hergestellt sein.To allow easy removal of contaminants, the inner wall membrane may be made of an easy-to-clean material.

Das zwischen den zumindest zwei Wandmemembranen angeordnete starre Abstandselement kann beim Transport hinderlich sein, weshalb das zumindest eine starre Abstandselement entlang seiner Länge einmal oder mehrere Male geteilt sein kann, sodaß ein Zusammenlegen des Wandelements ermöglicht wird.The arranged between the at least two wall membranes rigid spacer may be a hindrance during transport, which is why the at least one rigid spacer can be divided along its length once or several times, so that a collapsing of the wall element is made possible.

Weiters betrifft die Erfindung eine Zelt- oder Hallenkonstruktion unter Verwendung zumindest eines Wandelements mit zumindest einem starren Abstandselement.Furthermore, the invention relates to a tent or hall construction using at least one wall element with at least one rigid spacer element.

Aufgabe ist es dabei, eine Zelt- oder Hallenkonstruktion zu schaffen, welche mit einfachen Mitteln auf und abgebaut werden kann, und die sehr gute thermische und Dichtungs-Eigenschaften aufweist.Task is to create a tent or hall construction, which can be opened and taken down with simple means, and has very good thermal and sealing properties.

Erfindungsgemäß wird dies dadurch erreicht, daß das zumindest eine-starre Abstandselement von den Einspannelementen separiert angeordnet und an gegenüberliegenden Innenseiten der zumindest zwei Wandmembranen gelenkig mit diesen verbunden ist, sodaß sich das Abstandselement im gespannten Zustand der zumindest zwei Wandmembranen durch die auf diese ausgeübte Spannung so einstellt, daß die zumindest zwei Wandmembranen voneinander beabstandet gehalten sind, und daß das zumindest eine Wandelement einen tunnelförmigen -und-einem-die-Seitenwände-.. verbindenden Dachwandteil ausbildet.According to the invention this is achieved in that the at least one rigid spacer element is arranged separated from the clamping elements and hingedly connected to opposite inner sides of the at least two wall membranes, so that the spacer element in the tensioned state of the at least two wall membranes by the voltage applied thereto adjusts that the at least two wall membranes are kept spaced from each other, and that the at least one wall element forms a tunnel-shaped -and-one-the-Seitenwände- .. connecting roof wall part.

Auf diese Weise ist der gesamte Zelt oder Hallenquerschnitt mittels zumindest zweier durchgehend verlaufender Wandmembran-Bahnen aufgebaut, welche eine hohe Wärmedämmung und einen hohen Wärmeübergangswiderstand ermöglichen. Je nach Größe der aufzubauenden Zelt- oder Hallenkonstruktion kann eine beliebige Anzahl an solchen tunnelförmigen Querschnitten aneinandergereiht werden.In this way, the entire tent or hall cross-section is constructed by means of at least two continuous wall membrane webs, which allow a high thermal insulation and a high heat transfer resistance. Depending on the size of the tent or hall structure to be constructed, any number of such tunnel-shaped cross sections can be strung together.

Gemäß einer weiteren Ausführungsform der Erfindung können die Profilstäbe zum Einspannen der Wandmembranen entsprechend dem gewählten Tunnelquerschnitt entlang einer mehrfach geknickten Linie beginnend an einem ersten Fußpunkt und an einem von diesem beabstandeten zweiten Fußpunkt endend verlaufen, und entlang des Verlaufs der Profilstäbe können zwei Wandmembranen mit Abstandselementen eingespannt sein, sodaß zwischen den zwei Wandmembranen der Hohlraum ausgebildet ist.According to a further embodiment of the invention, the profile bars for clamping the wall membranes corresponding to the selected tunnel cross-section along a multi-kinked line beginning at a first base point and at a distance from this second foot point ending, and Along the course of the profile bars, two wall membranes can be clamped with spacer elements, so that the cavity is formed between the two wall membranes.

-Eine andere Weiterbildung der Erfindung kann darin bestehen, daß an den Knickstellen des Tunnelquerschnitts die innenseitig gelegen der zwei Wandmembranen durch Ausnehmen eines linsenartigen Ausschnitts in ihrer Längenausdehnung verkürzt ist, und daß ein Klettverschluß vorgesehen ist, durch den die Ausschnittränder verbindbar sind oder miteinander verschweißt sind. Dadurch wird ein Ausbauchen der zumindest zwei Wandmembranen an den Stellen, an denen sich einen Richtungsänderung im Verlauf der zumindest ; zwei Wandmembranen ergibt, verhindert.Another development of the invention may be that at the kinks of the tunnel cross-section, the inside of the two wall membranes is shortened by removing a lens-like cutout in their length, and that a hook and loop fastener is provided by the cutout edges are connected or welded together , This results in a bulging of the at least two wall membranes at the locations at which a change in direction in the course of at least; two wall membranes results prevented.

Es kann aber auch vorgesehen sein, daß die innenseitige Wandmembran zwei oder mehrere Male unterteilt ist, um ein leichteres Einziehen in ein Kederprofil zu gestatten.But it can also be provided that the inside wall membrane is divided two or more times to allow easier insertion into a Kederprofil.

Eine weitere Ausführungsform der Erfindung kann darin bestehen, daß entlang der Seitenwandteile eine weitere Außenwandmembran zwischen den Profilen gespannt ist, die einen Hinterlüftungszwischenraum zwischen der weiteren Außenwandmembran und den zwei Wandmembranen ausbildet. Im Gegensatz zu dem Lufthohlraum, der zwischen den zwei Wandmembranen des erfindungsgemäßen Wandelements vorhanden ist und der Wärmedämmung dient, ist der solcherart gebildete Hinterlüftungszwischenraum für den Durchzug von Luft gedacht, um die von außen durch die Außenwandmembran eindringende Strahlungswärme abführen zu können.A further embodiment of the invention may be that along the side wall portions, a further outer wall membrane is stretched between the profiles, forming a rear ventilation gap between the further outer wall membrane and the two wall membranes. In contrast to the air cavity, which is present between the two wall membranes of the wall element according to the invention and the thermal insulation is used, the thus formed rear ventilation space for the passage of air is intended to remove the penetrating from outside through the outer wall membrane radiant heat can.

Schließlich kann eine weitere Variante der Erfindung darin bestehen, daß zum Dachwandteil beabstandet eine Dachaußenwandmembran gespannt ist, die einen hinterlüfteten Kaltdach-Zwischenraum zwischen dem Dachwandteil und der Dachaußenwandmembran ausbildet. Der Kaltdach-Zwischenraum ist ebenso dazu gedacht, Strahlungswärme durch Konvektionsbewegung der im Kaltdach-Zwischenraum vorhandenen Luft abzuführen und ein Erwärmen des Zeit- oder Halleninneren zu vermeiden.Finally, a further variant of the invention may consist in that the roof wall part spaced a Dachaußenwandmembran is stretched, which is a ventilated cold roof space between the roof wall part and the Roof outer wall membrane forms. The cold roof space is also intended to dissipate radiant heat by convective movement of existing in the cold roof space air and to avoid heating the time or hall interior.

Fig. 1 zeigt ein Membran-Wandelement für die Errichtung einer Zelt- oder Hallenkonstruktion mit zwei Wandmembranen 1A, 1B, die an ihren zwei gegenüberliegenden Endbereichen in Einspannelementen 5 festgelegt sind. Fig. 1 shows a membrane wall element for the construction of a tent or hall construction with two wall membranes 1A, 1B, which are fixed at its two opposite end portions in clamping elements 5.

Die zwei Wandmembranen 1A, 1B sind an ihren gegenüberliegenden Endabschnitten 40 jeweils zusammengefügt und können z.B. aus Zeltleinwand oder einem anderen geeigneten Stoff, z.B. einem Kunststoff gebildet sein. Im eingespannten Zustand sind die zwei Wandmembranen 1A, 1B erfindungsgemäß durch zwei starre bzw. wenig elastische Abstandselemente 2 so voneinander beabstandet, daß sich zwischen diesen ein Hohlraum 6 ausbildet.The two wall membranes 1A, 1B are joined together at their opposite end portions 40 and may be formed, for example, of canvas or other suitable material, eg a plastic. In the clamped state, the two wall membranes 1A, 1B according to the invention by two rigid or less elastic spacer elements 2 are spaced from each other so that a cavity 6 is formed between them.

In Fig.4 ist eine vergrößerte Ansicht des Abstandselements 2 gezeigt, das ein starres, stabförmiges Zwischenstück 3 aufweist, an dessen Längsseiten flexible Streifen 4 angeformt sind, die innerhalb des Wandelements in Fig.1 mit den gegenüberliegenden Innenseiten der zwei Wandmembranen 1A, 1B verbunden sind, sodaß die Längsseiten des starren Zwischenstücks 3 gelenkig mit den Wandmembranen 1A, 1 B verbunden sind.In Figure 4 an enlarged view of the spacer 2 is shown, which has a rigid, rod-shaped intermediate piece 3, on the longitudinal sides of flexible strips 4 are formed, which within the wall element in Fig.1 are connected to the opposite inner sides of the two wall membranes 1A, 1B, so that the longitudinal sides of the rigid intermediate piece 3 are hingedly connected to the wall membranes 1A, 1B.

Die flexiblen Streifen können beispielsweise aus demselben Material wie die Wandmembranen 1A, 1 B oder einem anderen geeigneten Material gebildet sein.For example, the flexible strips may be formed of the same material as the wall membranes 1A, 1B or other suitable material.

In der in Fig.1 gezeigten Ausführungsform sind die Anlenkungsstellen an den Wandmembranen 1A, 1 B jeweils gleich weit von den Rändern der Endabschnitte der Wandmembranen 1A, 1 B beabstandet, wodurch das starre Zwischenstück 3 und die zu den Endabschnitten verlaufenden Membranteile im gespannten Zustand - im Querschnitt gesehen - ein gleichschenkeliges Dreieck ausbilden. Im Rahmen der Erfindung ist auch eine andere Art der Anordnung der Abstandselemente 2 möglich, welche im gespannten Zustand eine Beabstandung der Wandmembranen 1A, 1 B ergibt.In the in Fig.1 In the embodiment shown, the articulation points on the wall membranes 1A, 1B are equidistant from the edges of the end sections of the wall membranes 1A, 1B, whereby the rigid intermediate piece 3 and the membrane sections extending to the end sections in the tensioned state - seen in cross section - an isosceles Training triangle. In the context of the invention, a different type of arrangement of the spacer elements 2 is possible, which in the tensioned state results in a spacing of the wall membranes 1A, 1B.

Weiters können bei großen Abständen zwischen den Einspannelementen 5 auch mehrere über die Wandelementbreite verteilte Abstandselemente 2 ausgebildet sein, die durchgehend oder unterbrochen ausgebildet sein können, um die konstante Beabstandung zwischen den Wandmembranen 1A, 1B über die gesamte Wandelementbreite aufrechterhalten zu können.Furthermore, at large distances between the clamping elements 5, a plurality of distributed over the wall element width spacer elements 2 may be formed, which may be continuous or interrupted, in order to maintain the constant spacing between the wall membranes 1A, 1B over the entire wall element width.

Das erfindungsgemäße Wandelement ist in Fig.1 im eingespannten Zustand zwischen den beiden Einspannelementen 5 und in Fig.2 im nicht gespannten Zustand gezeigt. Wenn auf die Einspannelemente 5 in Richtung der Pfeile P Kraft ausgeübt wird, wird das erfindungsgemäße Wandelement gestreckt oder gespannt, indem die Streck-Kräfte auf die Wandmembranen 1A und 1B übertragen werden, welche aufgrund der Verbindung der Wandmembranen 1A, 1B mit den starren Zwischenstücken 3 so wirken, daß sich diese quer zu den Wandmembranen 1A und 1 B stellen und zu einer Trennung der Wandmembranen 1A, 1B führen. Damit entsteht ein mit Luft gefüllter, abgeschlossener Hohlraum 6 zwischen den Wandmembranen 1A und 1B, sofern diese entlang ihrer gesamten Berandung entsprechend dichtend miteinander verbunden sind. Dieser Hohlraum 6 bewirkt die gewünschte Isolationsschicht.The wall element according to the invention is in Fig.1 in the clamped state between the two clamping elements 5 and in Fig.2 shown in the untensioned state. When force is exerted on the clamping elements 5 in the direction of the arrows P, the wall element according to the invention is stretched or tensioned, by transferring the stretching forces to the wall membranes 1A and 1B, which, due to the connection of the wall membranes 1A, 1B with the rigid spacers 3, act to face the wall membranes 1A and 1B and to separate the wall membranes 1A , 1B lead. This creates an air-filled, closed cavity 6 between the wall membranes 1A and 1B, provided that they are connected together sealingly along their entire boundary. This cavity 6 causes the desired insulation layer.

In Fig. 3 ist eine weitere Ausführungsform des erfindungsgemäßen Wandelements gezeigt, bei der insgesamt drei Wandmembranen, eine Innenwandmembran 1A, eine Außenwandmembran 1B und eine Zwischenwandmembran 1C mit Hohlräumen 6 aufgespannt sind, woraus sich eine noch bessere Wärmeisolation ergibt.In Fig. 3 shows a further embodiment of the wall element according to the invention, in which a total of three wall membranes, an inner wall membrane 1A, an outer wall membrane 1B and an intermediate wall membrane 1C are clamped with cavities 6, resulting in an even better thermal insulation.

An den Längsseiten der starren Zwischenstücke 3 sind dabei jeweils flexible Streifen 4 angeformt, die mit den gegenüberliegenden Innenseiten der Innenwandmembran und der Zwischenwandmembran 1A, 1C sowie mit der Zwischenwandmembran und der Außenwandmembran 1C, 1B verbunden sind, sodaß die Längsseiten der insgesamt vier starren Zwischenstücke 3 gelenkig mit den Wandmembranen 1A, 1B, 1C verbunden sind, wobei die Anlenkungsstellen an den Wandmembranen 1A, 1B, 1C so gewählt sind, daß die zu den Endabschnitten verlaufenden Membranteile der Innen- und der Außenwandmembran 1A, 1B und die starren Zwischenstücke 3 im gespannten Zustand - im Querschnitt gesehen - ein gleichschenkeliges Dreieck ausbilden, während die Zwischenwandmembran 1C entlang der Höhenlinie des gleichschenkeligen Dreiecks durchgehend eben verläuft.In each case, flexible strips 4 are integrally formed on the longitudinal sides of the rigid intermediate pieces 3, which are connected to the opposite inner sides of the inner wall membrane and the partition wall membrane 1A, 1C and to the partition wall membrane and the outer wall membrane 1C, 1B, so that the longitudinal sides of the four rigid intermediate pieces 3 are hingedly connected to the wall membranes 1A, 1B, 1C, wherein the articulation points on the wall membranes 1A, 1B, 1C are selected so that the extending to the end portions membrane parts of the inner and outer wall membrane 1A, 1B and the rigid intermediate pieces 3 in the tensioned Condition - seen in cross-section - form an isosceles triangle, while the partition wall membrane 1C along the contour line of the isosceles triangle is continuously flat.

Die vorzugsweise stabförmigen Zwischenstücke 3 sind aus einem geeigneten steifen oder halbsteifen Material gebildet, das dafür sorgt, daß der gewünschte Abstand zwischen den Wandmembranen 1A, 1B, 1C entsteht und aufrecht erhalten wird, wenn das erfindungsgemäße Wandelement aufgespannt bzw. gespannt gehalten wird. Eine Einschränkung hinsichtlich Form oder Material der Zwischenstücke 3 besteht nicht, solange sie ihre Funktion im Rahmen der Erfindung erfüllen.The preferably rod-shaped intermediate pieces 3 are formed from a suitable rigid or semi-rigid material, which ensures that the desired distance between the wall membranes 1A, 1B, 1C is formed and maintained when the wall element according to the invention held clamped or stretched becomes. A limitation in terms of shape or material of the spacers 3 does not exist, as long as they fulfill their function within the scope of the invention.

Die angewandten Membranwand- oder Leinwandtypen sind vom Prinzip der Erfindung unabhängig. Notwendig ist lediglich, daß sie sich verbinden lassen, beispielsweise durch Kleben, Schweißen oder ähnliche Techniken. Ein Beispiel für eine Membranwand, die sich für die Erfindung eignet, ist eine Ausführungsform, bei der die Außenwandmembran 1B durch Polyurethan gebildet ist, das z.B. gegen Kampfgase oder Ähnliches abdichtet und bei der die Innenwandmembran 1A aus einem leicht zu reinigenden Material besteht, wohingegen die Zwischenwandmembran 1C zwecks Wärmereflexion aluminiumbeschichtet ist.The applied membrane wall or canvas types are independent of the principle of the invention. It is only necessary that they can be connected, for example by gluing, welding or similar techniques. An example of a membrane wall suitable for the invention is an embodiment in which the outer wall membrane 1B is formed by polyurethane, e.g. seals against war gases or the like, and wherein the inner wall membrane 1A is made of an easy-to-clean material, whereas the partition wall membrane 1C is aluminum-coated for heat reflection.

Es kann auch eine geeignete Beschichtung angewendet werden, die in adäquater Form ausreichend gegen elektromagnetische Strahlung schützt, sodaß die mit dem erfindungsgemäßen Wandelement gebildete Zelt- oder Hallenkonstruktion wie ein Farraday'scher Käfig wirkt.It is also possible to use a suitable coating which adequately protects against electromagnetic radiation adequately, so that the tent or hall construction formed with the wall element according to the invention acts like a Farraday cage.

Die Wandmembranen können vollständig abgedichtet entlang aller Kanten zusammengefügt sein, in diesem Fall müssen jedoch geeignete Ventilationsvorrichtungen angebracht werden, damit Luft eindringen und den Hohlraum oder die Hohlräume füllen kann, wenn das erfindungsgemäße Wandelement aufgespannt wird.The wall membranes may be completely sealed together along all edges, but in this case suitable ventilation means must be provided to allow air to penetrate and fill the cavity or cavities when the wall element of the invention is deployed.

Obwohl nur Wandelemente gezeigt werden, die jeweils zwei und drei Wandmembranen umfassen, können natürlich mehrere Membranschichten mit den dazugehörigen Abstandselementen verwendet werden, ohne den Rahmen der Erfindung zu verlassen. Es können auch mehr als zwei Abstandselemente zwischen den Wandmembranen angebracht werden, falls dies erwünscht oder aus Stabilitätsgründen für notwendig erachtet wird.Although only wall elements are shown, each comprising two and three wall membranes, it should be understood that a plurality of membrane layers with associated spacers may be used without departing from the scope of the invention. Also, more than two spacers may be mounted between the wall membranes, if desired or deemed necessary for reasons of stability.

Erfindungsgemäß konstruierte Hallen- oder Zeltkonstruktionen können auch beheizt oder eventuell mit einer Kühlanlage ausgestattet zur Anwendung kommen.Indoor or tent constructions constructed according to the invention can also be heated or possibly equipped with a cooling system.

Um eine gleichmäßige Einspannung der Wandmembranen zu gewährleisten sind in der Ausführungsform gemäß Fig.7 und 11 die Einspannelemente durch Profilstäbe 55, z.B. aus Aluminium gebildet und es ist an den zusammengefügten Endabschnitten 40 randseitig eine Kederschnur 36 vorgesehen. Die Einspannung kann aber im Rahmen der Erfindung auch ohne eine solche Kederschnur vorgenommen werden.In order to ensure a uniform clamping of the wall membranes are in the embodiment according to Figure 7 and 11 the clamping elements formed by profiled bars 55, for example made of aluminum and it is at the joined end portions 40 edge Kederschnur 36 is provided. However, the clamping can be made within the scope of the invention without such Kederschnur.

Zusätzlich zu der aus den Wandmembranen 1A, 1B gebildeten erfindungsgemäßen Doppelmembran ist eine herkömmliche Wandmembran 79 von den Profilstäben 55 zur Ausbildung eines erfindungsgemäßen Wandelements eingespannt.In addition to the double membrane of the invention formed from the wall membranes 1A, 1B, a conventional wall membrane 79 is clamped by the profiled bars 55 to form a wall element according to the invention.

Die Profilstäbe 55 weisen hinterschnittene Längskanäle 30 auf, in welche die Kederschnüre 36, 48 der zusammengefügten Wandmembranen 1A, 1B sowie der Wandmembran 79 eingezogen sind (Fig.7).The profile bars 55 have undercut longitudinal channels 30, in which the Kederschnüre 36, 48 of the assembled wall membranes 1A, 1B and the wall membrane 79 are retracted ( Figure 7 ).

Zwischen den Profilstäben 55 ist eine Spannvorrichtung 15, die in Fig.5 und 6 im Detail dargestellt ist, mit Spannstäben 25, 26 vorgesehen, über welche die in den Profilstäben 55 festgelegten Wandmembranen 1A, 1B sowie 79 auseinandergespannt sind.Between the profile bars 55 is a clamping device 15, which in Fig.5 and 6 is shown in detail, provided with tension rods 25, 26, over which the fixed in the profile rods 55 wall membranes 1A, 1B and 79 are spread apart.

Die Spannvorrichtung 15 ist über eine Kniehebelvorrichtung 75 betätigbar, deren Antriebsspindel 16 zur Betätigung durch Gelenke 9, 10, 11 gelagerte Kniehebel 17,18 quer zur Längsachse der Spannstäbe 25, 26 orientiert ist. Über ein Betätigungselement 12 kann die Antriebsspindel 16 gedreht und damit eine Bewegung von Verschiebungselementen 38, 39 bewirkt werden. Die Spannstäbe 25, 26 weisen ein Hohlprofil auf, mit dem sie an einem Ende auf Führungen 13 der Kniehebelvorrichtung 75 aufgeschoben sind und können zum Spannen der Wandmembranen durch die von den Kniehebeln 17, 18 betätigten Verschiebeelemente 38, 39 entsprechend auseinander bewegt werden.The tensioning device 15 can be actuated via a toggle lever device 75, the drive spindle 16 of which is oriented transversely to the longitudinal axis of the tensioning rods 25, 26 for actuation by knuckles 9, 10, 11 mounted toggle levers 17,18. Via an actuating element 12, the drive spindle 16 is rotated and thus a movement of displacement elements 38, 39 causes. The tension rods 25, 26 have a hollow profile, with which they are pushed at one end on guides 13 of the toggle device 75 and can be used to tighten the Wall diaphragms are moved apart by the actuated by the toggle levers 17, 18 sliding elements 38, 39.

An das andere Ende der Spannstäbe 25, 26 ist jeweils ein Flanschstück 29 zur Fixierung an den Profilstäben 55 angebracht. In der Ausführungsform der Fig. 7 sind zu diesem Zweck Schrauben 49 mit ihren Köpfen in hinterschnittenen Schlitzen des Profilstabes 55 gehalten und das jeweilige Flanschstück 29 mittels Muttern gegen den Profilstab 55 verschraubt.At the other end of the clamping rods 25, 26 each have a flange 29 is attached to the profile bars 55 for fixing. In the embodiment of the Fig. 7 For this purpose, screws 49 are held with their heads in undercut slots of the profile bar 55 and the respective flange 29 is screwed by nuts against the profile bar 55.

Im gespannten Zustand verlaufen die Längsseiten des starren Zwischenstücks 3 zwischen den zwei Wandmembranen 1A, 1B parallel zu den einander gegenüberliegenden Zusammenfügungslinien 90 der Wandmembranen 1A, 1B (Fig.11).In the tensioned state, the longitudinal sides of the rigid intermediate piece 3 between the two wall membranes 1A, 1B extend parallel to the mutually opposite joining lines 90 of the wall membranes 1A, 1B (FIG. Figure 11 ).

Bei sehr langen Profilstäben 55 kann das Einziehen der Kederschnur 36 sehr mühsam sein, weshalb in der Ausführungsform gemäß Fig. 8 die Profilstäbe 55' Längskanäle 31 aufweisen, in die die Kederschnüre 36 der zusammengefügten Wandmembranen 1A, 1B eingelegt und danach die Längskanäle 31 mittels entsprechend geformten Deckschienen 56 so verschlossen werden, daß die Kederschnüre 36 in den Profilstäben 55' fixiert sind. Die Deckschienen werden dabei mit Schrauben 57 fixiert, die in den Profilstäben 55' eingesetzten Muttern 58 eingeschraubt sind.For very long profile bars 55, the retraction of Kederschnur 36 can be very tedious, which is why in the embodiment according to Fig. 8 the profile bars 55 'longitudinal channels 31, in which the Kederschnüre 36 of the assembled wall membranes 1A, 1B inserted and then the longitudinal channels 31 are closed by means of correspondingly shaped cover rails 56 so that the Kederschnüre 36 are fixed in the profile bars 55'. The cover rails are fixed with screws 57, which are screwed into the profiled bars 55 'inserted nuts 58.

Im Ausführungsbeispiel gemäß Fig. 10 ist das zumindest eine starre Abstandselement 2 entlang seiner Länge einmal oder mehrere Male geteilt, sodaß ein Zusammenlegen des Wandelements ermöglicht wird. Dies kann auch für Wandelemente mit drei oder mehreren parallelen Wandmembranen vorgesehen sein.In the embodiment according to Fig. 10 the at least one rigid spacer element 2 is divided once or several times along its length so that the wall element can be folded together. This may also be provided for wall elements with three or more parallel wall membranes.

Fig.9 zeigt eine Ausführungsform einer Zelt- oder Hallenkonstruktion, die unter Verwendung eines erfindungsgemäßen Wandelements aufgebaut ist, wobei erfindungsgemäß das Wandelement einen tunnelförmigen Querschnitt mit zwei Seitenwandteilen 80, 81 und einem die Seitenwände verbindenden Dachwandteil 90 ausbildet. Die Form des Querschnitts kann entsprechend den Anforderungen abgeändert werden, durch Aneinanderreihung mehrerer Wandelemente des in Fig.9 gezeigten Typs zu einer Zelt- oder Wandkonstruktion ist eine beliebige Längserstreckung derselben möglich. An den Enden können ebenfalls erfindungsgemäße Wandelemente angebracht werden. Figure 9 shows an embodiment of a tent or hall construction under Use of a wall element according to the invention is constructed, according to the invention, the wall element forms a tunnel-shaped cross-section with two side wall parts 80, 81 and a side wall connecting the wall panels 90.

Entlang des Verlaufs der Profilstäbe 55 sind die zwei Wandmembranen 1A, 1B mit Abstandselementen 2 (in Fig.9 nicht gezeigt) eingespannt, sodaß zwischen den zwei Wandmembranen 1A, 1B der Hohlraum 6 (in Fig. 9 nicht gezeigt) ausgebildet ist. Das gesamte Tunnelprofil ist somit mit der Doppelmembran 1A, 1B ausgekleidet.The profile bars 55 (in Figure 9 not shown) for clamping the wall membranes 1A, 1B corresponding to the selected tunnel cross-section extend along a multiply kinked line starting at a first base 101 and at a second foot 102 spaced therefrom. Along the course of the profile bars 55, the two wall membranes 1A, 1B with spacers 2 (in Figure 9 not shown), so that between the two wall membranes 1A, 1B of the cavity 6 (in Fig. 9 not shown) is formed. The entire tunnel profile is thus lined with the double membrane 1A, 1B.

An den Knickstellen des Tunnelquerschnitts sind die innenseitig gelegenen der zwei Wandmembranen 1A, 1B durch Ausnehmen eines nicht dargestellten linsenartigen Ausschnitts in ihrer Längenausdehnung verkürzt und die Ausschnittränder können durch einen Klettverschluß 130 verbunden werden oder miteinander verschweißt sein. Weiters kann die innenseitige Wandmembran z.B. zwei oder mehrfach unterteilt sein, z.B. in zwei Seitenwandteile und einen Deckwandteil, um das Einziehen in das Kederprofil zu erleichtern.At the kinks of the tunnel cross section, the inside of the two wall membranes 1A, 1B are shortened in length by removing a lenticular cutout, not shown, and the cutout edges can be connected by a hook and loop fastener 130 or welded together. Furthermore, the inside wall membrane can e.g. divided two or more times, e.g. in two side wall parts and a top wall part to facilitate insertion into the piping profile.
