Description

Die Erfindung betrifft eine Baukonstruktion, insbesondere eine über­dachte Halle, mit einem fachwerkartigen räumlichen Gerüst sowie wenigstens einer daran festliegenden flexiblen Haut als Begrenzung einer durch ein Strömungsmedium beaufschlagten Kammer.The invention relates to a building construction, in particular a covered hall, with a framework-like spatial framework and at least one flexible skin attached to it as a boundary of a chamber acted upon by a flow medium.

Eine derartige Baukonstruktion ist aus der DE-AS 2 228 389 in Form eines mit Ein- und Auslässen für das -- gasförmige - Strömungsmedium versehenen Kissens für vom Atmosphärendruck abweichendem Innendruck gehaltene Befüllung aus Blasmedium bekannt, welches an Gerüstseilen und -rahmen festliegt. Mehrere derartige Kissen bilden eine gemeinsame Überdachung. Aufgabe der Vorerfindung war es, die Nachteile von Tragkonstruktionen aus durchgehenden Stäben für einzelne, beispielsweise an der Oberfläche der Tragkonstruktion festliegende Häute bzw. für von einem starren Innengerüst ausgesteifte Pneuelemente zu beseitigen.Such a construction is known from DE-AS 2 228 389 in the form of a cushion provided with inlets and outlets for the - gaseous - flow medium for filling of the blown medium which is kept at internal pressure deviating from atmospheric pressure and which is fixed to scaffolding cables and frames. Several such pillows form a common roof. The object of the present invention was to eliminate the disadvantages of supporting structures made of continuous bars for individual skins, for example those fixed to the surface of the supporting structure, or for connecting elements stiffened by a rigid inner frame.

Bei Baukonstruktionen mit mehreren aneinandergesetzten Kissen haben sich zum einen die aufwendigen Montagearbeiten als nachteilig erwiesen, mehr jedoch die Mängel an den erforderlichen Dichtungszonen. Außerdem entsprach das Kissendach nach DE-AS 2 228 389 oder DE-AS 2 052 864 nicht den Anforderungen an Lichtanfall im Bauwerksinneren.In the case of building constructions with several cushions placed against one another, the complex assembly work has proven to be disadvantageous, but more the defects in the required sealing zones. In addition, the cushion roof according to DE-AS 2 228 389 or DE-AS 2 052 864 did not meet the requirements for light incidence inside the building.

Angesichts dieser Gegebenheiten hat sich der Erfinder das Ziel gesetzt, eine Baukonstruktion der eingangs erwähnten Art zu schaffen, welche die beim Stand der Technik erkannten Mängel beseitigt und ins­besondere für die Überdachung von Schwimmbädern, Bepflanzungsebenen und dgl. bei günstigen Lichtverhältnissen im Innenraum geeignet sein soll.In view of these circumstances, the inventor has set himself the goal of creating a building construction of the type mentioned at the outset which eliminates the shortcomings recognized in the prior art and is intended in particular to be suitable for roofing swimming pools, planting levels and the like in favorable light conditions in the interior.

Zur Lösung dieser Aufgabe führt, daß zwischen benachbart verlaufenden Bindern des Gerüstes zwei Folienbahnen aus bevorzugt transluzentem Kunststoff übereinander festgelegt sind, die zwischen den beiden Bindern eine streifenartig gestreckte sowie luftdichte Kammer bilden.To achieve this object, two film webs of preferably translucent plastic are defined one above the other between adjacent binders of the framework, which form a strip-like, airtight chamber between the two binders.

Nach einem weiteren und besonderen Merkmal der Erfindung verläuft zudem zwischen beiden Folienbahnen eine Mittelfolie, die zwei luftbeaufschlagbare Kammern voneinander trennt. Dank des Überdruckes in den Kammern sind - wie auch der Stand der Technik lehrt -- die Folienbahnen gespannt und damit flattersicher. Erfindungsgemäß auf der Außenfolie auflastende Querseile schützen die bevorzugt als langgestreckte sphärische Dreiecke oder rechteckige Kissenbahnen vorgesehenen Luftkammern vor allem gegen Sogkräfte.According to a further and special feature of the invention, a middle film also runs between the two film webs and separates two chambers that can be acted upon by air. Thanks to the overpressure in the chambers - as the state of the art teaches - the film webs are stretched and thus flutter-proof. According to the invention, transverse ropes which load the outer film protect the air chambers, which are preferably provided as elongated spherical triangles or rectangular cushion paths, above all against suction forces.

Als günstig haben sich Konstruktionen erwiesen, deren Außenkammer mit stehender Luft und deren Innenkammer mit dem ziehenden Strömungsmedium gefüllt sind - letzteres zirkuliert zwischen Ein- und Auslaß und kann auch vorgewärmt werden. Damit ist jeglicher Kondensationsvorgang in der Innenkammer unterbunden, ein möglicherweise in der Außenkammer entstehendes Kondensat einer Menge von etwa 15 g je Kubikmeter ist vernachlässigbar.Constructions have proven to be inexpensive, the outer chamber of which is filled with standing air and the inner chamber of which is drawn by the pulling flow medium - the latter circulates between the inlet and outlet and can also be preheated. This prevents any condensation process in the inner chamber; any condensate that may be generated in the outer chamber of around 15 g per cubic meter is negligible.

Die Ein- und Auslässe können sowohl in Längsrichtung der Bänder als auch quer dazu zueinander in Abstand angeordnet sein, bestimmend hierfür ist die optimale Länge der Strömungsbahn im Kisseninneren.The inlets and outlets can be arranged at a distance both in the longitudinal direction of the bands and transversely to one another, which is determined by the optimal length of the flow path inside the cushion.

Auch hat es sich als günstig erwiesen an der innenraumseitigen Oberfläche der Kissenkonstruktion eine Schicht aus erwärmter Luft zu erzeugen, beispielsweise durch nahe der Innenfolie angebrachte Blasdüsen.It has also proven to be advantageous to generate a layer of heated air on the interior surface of the pillow construction, for example by means of blowing nozzles attached near the inner film.

Die Binder liegen im Rahmen einer Ausführung der Erfindung einends bodenwärts beispielsweise auf Pfetten fest und verlaufen zu einem in Abstand zum Boden angeordneten Verbindungselement hin, mit dem sie andernends verbunden sind; die bevorzugte Form der Baukonstruktion ist kalotten- oder halbkugelartig. Die Binder sind am Boden kreisartig festgelegt und zu einem zentrischen Dachring unter Bildung eines kalottenartigen Gerüstes gekrümmt. Diese Binder sind die Hauptträger oder Sparren des Gebäudegestells und vorteilhafterweise durch Querstäbe miteinander verbunden. Etwa an den Eckpunkten der von den Bindern und den Querstäben begrenzten Felder können zur besseren Aussteifung Diagonalverspannungen angreifen.In the context of an embodiment of the invention, the trusses are fixed on the floor at one end, for example on purlins, and run to a connecting element which is arranged at a distance from the floor and to which they are connected at the other end; the preferred form of construction is dome-shaped or hemispherical. The trusses are fixed in a circle at the bottom and curved into a central roof ring to form a dome-like structure. These trusses are the main girders or rafters of the building frame and are advantageously connected to one another by cross bars. For example, at the corner points of the fields delimited by the trusses and the cross bars, diagonal braces can attack for better stiffening.

Zur Vereinfachung des Aufbaus und zur besseren Abdichtung ist jede Folienbahn erfindungsgemäß mit ihren beiden Längsrändern -- aber gegebenenfalls auch an den Schmalseiten -- lösbar an Anschlußprofilen der Binder luftdicht festgelegt.To simplify the construction and for better sealing, each film web according to the invention with its two longitudinal edges - but possibly also on the narrow sides - is releasably fixed airtight on the connecting profiles of the binder.

Hierzu hat es sich als günstig erwiesen, auf dem Binder ein darauf in Längsrichtung -- oder quer dazu -- verlaufendes Rinnenprofil festzulegen, an dessen Längskanten jeweils ein -- stranggepreßtes -- Anschlußprofil angebracht sein kann. Dieses kann aber bei bestimmten Ausführungen auch unmittelbar dem Binder aufliegen.For this purpose, it has proven to be advantageous to fix a gutter profile running thereon in the longitudinal direction - or transversely thereto - to the longitudinal edges of which a - extruded - connecting profile can be attached. In certain versions, however, this can also rest directly on the binder.

Das Rinnenprofil oder ein entsprechend geformtes Anschlußprofil leitet zwischen jeweils zwei der gestreckten Kammern das Regenwasser ab, die Anschlußprofile erlauben zudem den luftdichten Anschluß der Folien -- und deren Austausch -- in bestechend einfacher Weise.The gutter profile or a correspondingly shaped connection profile drains the rainwater between two of the stretched chambers, the connection profiles also allow the airtight connection of the foils - and their replacement - in an impressively simple manner.

Vorteilhafterweise ist ein weiteres Anschlußprofil in einem Abstand zur Oberkante des ersten Anschlußprofils zur Bestimmung des Abstandes der Folien voneinander am Binder festgelegt. Dieses Anschlußprofil weist wenigstens eine nach oben offene hinterschnittene Nut sowie ein gewinkelt anschließendes, nach oben weisendes Rinnenprofilstück zur Aufnahme und Ableitung von möglichem Kondensat am Kammerrand auf.A further connection profile is advantageously fixed to the binder at a distance from the upper edge of the first connection profile for determining the distance between the foils. This connection profile has at least one undercut groove which is open at the top and an angled, upwardly facing channel profile piece for receiving and draining off possible condensate at the edge of the chamber.

Eine günstige weitere Ausführung des Anschlußprofils ist mit wenigstens zwei in Abstand zueinander verlaufenden hinterschnittenen Nuten versehen, bevorzugt als Winkelstück mit jeweils einem Schenkel zugeordneter Nut ausgebildet. Dieses Anschlußprofil ist am Binder lösbar angeordnet, wohingegen das andere Anschlußprofil - wie gesagt -- vom Regenwasserablauf abragt.A favorable further embodiment of the connection profile is provided with at least two undercut grooves running at a distance from one another, preferably in the form of an angle piece with a groove assigned to each leg. This connection profile is detachably arranged on the truss, whereas the other connection profile - as mentioned - protrudes from the rainwater drain.

Zur Handhabungserleichterung ist in den hinterschnittenen Nuten der/des Anschlußprofile/s jeweils ein Klemmorgan vorgesehen, das den eingelegten Folienrand in der hinterschnittenen Nut luftdicht festlegt. Das Klemmorgan kann auch als Kederwulst in der Folienbahn verlaufen.To facilitate handling, a clamping member is provided in the undercut grooves of the connection profile (s), which fixes the inserted film edge in the undercut groove in an airtight manner. The clamping element can also run as a welt bead in the film web.

Die Bestückung der Binder mit den Anschlußprofilen ermöglicht einen schnellen und luftdichten Einbau der Folienbahn; bei zunehmendem Innendruck legt sich letztere immer dichter an die Nutwände an.Equipping the trusses with the connection profiles enables a quick and airtight installation of the film web; with increasing internal pressure, the latter presses closer to the groove walls.

Im Rahmen der Erfindung ragen vom Binder Befestigungsschrauben auf, an denen die auf der äußeren Folie teilweise aufliegenden Querseile ange­bracht, vorteilhafterweise an einer Flügellasche der Be­festigungsschraube angelenkt, sind.In the context of the invention, fastening screws protrude from the binder, on which the transverse cables partially resting on the outer film are attached, advantageously articulated on a wing flap of the fastening screw.

Die Einspannung der Folie in der beschriebenen Art verhindert weitest­gehend das Entstehen von Kondensationserscheinungen im Kammerinnen­raum.The clamping of the film in the manner described largely prevents the appearance of condensation in the chamber interior.

Der Werkstoff für die Folien ist ein modifiziertes Ethylen-Tetrafluorethylen-Copolymer; diese flammwidrige Folie ist hochtransparent und witterungsbeständig. Die Lichtdurchlässigkeit im Bereich des sichtbaren Lichtes beträgt beispielsweise bei einer 100-µm-Folie 94 % bis 97 % (Gesamtlicht), die Transmission im ultravioletten Bereich (320 bis 380 nm) 83 % bis 88 %.The material for the films is a modified ethylene-tetrafluoroethylene copolymer; this flame-retardant film is highly transparent and weatherproof. The light transmittance in the range of visible light is, for example, 94% to 97% (total light) in the case of a 100 μm film, the transmission in the ultraviolet range (320 to 380 nm) is 83% to 88%.

Diese Folie ist sehr gut UV-durchlässig im Spektralbereich der Sonnen­einstrahlung. Dies erlaubt nicht nur einen optimalen Pflanzenwuchs unterhalb der Überdachung, sondern auch ein Bräunen menschlicher Haut entsprechend den Bedingungen in freier Natur.This film is very UV-transparent in the spectral range of solar radiation. This not only allows optimal plant growth below the roof, but also tans human skin according to the conditions in the wild.

Außerdem ist die Folie mit einem hohen Absorptionsgrad im Infrarot-­Bereich (Wärmerückhaltevermögen) ausgestattet. Sie nimmt kein Wasser auf, ist lösemittel- und chemikalienbeständig sowie schmutzabweisend.The film is also equipped with a high degree of absorption in the infrared range (heat retention).

Ein in der Zeichnung nicht dargestelltes Schwimmbecken, eine Pflanzen­landschaft od.dgl. wird von einer Dachkuppel 10 eines Bodendurch­messers d von - im gewählten Ausführungsbeispiel -- 40 m überspannt. Diese ruht auf einer bei 12 angedeuteten Bodenplatte mit umlaufender Drainage 13 und aufliegendem Belüftungssystem 11.A swimming pool, a plant landscape or the like, not shown in the drawing. is spanned by a roof dome 10 with a floor diameter d of - in the selected exemplary embodiment - 40 m. This rests on a base plate indicated at 12 with all-round drainage 13 and ventilation system 11 resting thereon.

Die Dachkuppel 10 weist zwanzig -- eine Kalotte bestimmende -- radial gestellte Bogenbinder 14 eines Bogenmaßes b von etwa 25 m sowie eines Bodenabstandes a zueinander von etwas mehr als 6 m auf.The roof dome 10 has twenty radially positioned arch binders 14 that determine a spherical cap and have a radian measure b of approximately 25 m and a ground clearance a of slightly more than 6 m.

Diese Bogenbinder 14 ruhen mit ihrem unteren Ende auf der Bodenplatte 12 und sind andernends an einen zentrischen Dachring 16 angeschlossen, dessen Durchmesser e hier 2,25 m und dessen obere Höhe h über der Bodenplatte 15 m messen. Jeweils zwei benachbarte Bogenbinder 14 bilden ein in der gekrümmten Ebene der Kalotte gebogenes, sich nach oben verjüngendes Schalenfeld 20 in Form eines gestreckten sphärischen Dreiecks, in dem vier -- beidends an den beiden Bogenbindern 14 festliegende -- Querstäbe 18 verlaufen.These bow ties 14 rest with their lower end on the base plate 12 and are connected at the other end to a central roof ring 16, the diameter e of which here measures 2.25 m and the upper height h above the base plate 15 m. In each case two adjacent arch binders 14 form a shell field 20 which is curved in the curved plane of the calotte and tapers upwards in the form of an elongated spherical triangle in which four transverse rods 18 run, which are fixed on both arch binders 14.

Der Bodenabstand i₁ eines unteren aus Querstäben 18 bestehenden Ringes 19d beträgt beispielsweise 4,7 m, der Bodenabstand i₂ des nächst­höheren Ringes 19m etwa 8,7 m. Über letzterem befindet sie in einem Abstand q von 3 m ein weiterer Ring 19n. Die in Fig. 1, 2 erkennbaren vier Ringe 19, 19n, 19m, 19t begrenzen mit den sie querenden Bogen­bindern 14 -- innerhalb zweier Bogenbinder 14 vier -- sich nach oben hin verjüngende Felder 17, deren jedes von zwei sich kreuzenden Diagonalseilen 15 durchspannt ist; letztere sind an den Durchdrin­gungsstellen Bogenbinder 14/Querstab 18 festgelegt.The ground clearance i₁ of a lower crossbar 18 existing ring 19 d is for example 4.7 m, the ground clearance i₂ of the next higher ring 19 m is about 8.7 m. Another ring 19 n is located above the latter at a distance q of 3 m. The four rings 19, 19 n , 19 m , 19 t which can be seen in FIGS. 1, 2, with the arch binders 14 crossing them - within two arch binders 14 four - tapering fields 17, each of which intersect two Diagonal ropes 15 is spanned; the latter are fixed at the penetration points of the bow tie 14 / crossbar 18.

Jedes der Schalenfelder 20 ist mittels dreier Folien 22, 23, 24 aus transluzentem Werkstoff ausgefacht; diese Folien 22, 23, 24 sind zwischen ihrem Binderpaar 14 über dessen gesamte Bogenlänge b eingespannt.Each of the shell fields 20 is fanned out by means of three foils 22, 23, 24 made of translucent material; these foils 22, 23, 24 are clamped between their pair of binders 14 over their entire arc length b.

Die drei übereinander angeordneten Folien 22, 23, 24 begrenzen zwei Luftkammern 25, 26, denen bodenseitig Luft zugeführt wird. Letztere wird mittels einer Niederdruckpneumatik gepumpt, spannt die Folien 22 bis 24 und erzeugt so eine einheitliche großflächige und flattersichere Ausfachung in Form eines Kissens 27 zwischen den Bogenbinderpaaren 14. Auf die Außenfolie 22 sind verstärkende Querseile 28 gelegt und beidends im Bereich der Bogenbinder 14 befestigt.The three foils 22, 23, 24 arranged one above the other delimit two air chambers 25, 26, to which air is supplied at the bottom. The latter is pumped by means of low-pressure pneumatics, tensioning the foils 22 to 24 and thus produces a uniform, large-area and flutter-proof infill in the form of a cushion 27 between the pairs of bow ties 14. Reinforcing cross cables 28 are placed on the outer film 22 and fastened on both ends in the area of the bow ties 14.

Auf jedem der Bogenbinder 14 liegt gemäß Fig. 5, 6 der Sockelabschnitt 30 eines Metallprofiles als Regenablaufrinne 31 auf, welche durch Befestigungsschrauben 34 gehalten ist. Letztere durchsetzen jeweils einen Rohrstumpf 35 mit Flügellaschen 36.5, 6, the base section 30 of a metal profile rests as a rain gutter 31, which is held by fastening screws 34. The latter each pass through a pipe stub 35 with wing flaps 36.

An jeder dieser Flügellasche 36 ist mittels eines Bolzens 38 eine Seilöse 29 des Querseiles 28 angelenkt. Spanneinrichtungen der Querseile 28 sowie der Diagonalseile 15 sind in der Zeichnung aus Gründen der Übersichtlichkeit nicht wiedergegeben.On each of these wing flaps 36, a cable eyelet 29 of the cross cable 28 is articulated by means of a bolt 38. Tensioning devices for the cross cables 28 and the diagonal cables 15 are not shown in the drawing for reasons of clarity.

Die geneigten Seitenschenkel 32 der Regenabflußrinne 31 tragen end­wärts jeweils ein aus einer Aluminiumlegierung stranggepreßtes An­schlußprofil 40, das querschnittlich aus einer L-förmigen Kondensat­fangrinne 41 und einem anschließenden Klemmprofil 42 besteht; letzteres nimmt in einer hinterschnittenen Nut 43 den Bereich eines Längsrandes 21 der Außenfolie 22 sowie einen Klemmstreifen 44 auf. Der Klemmstreifen 44 gewährleistet die Festlegung der gespannten Außenfolie 22 im Klemmprofil 42 des Anschlußprofiles 40. Der horizontale Abstand s zwischen zwei Außenfolien 22 in Fig. 6 beträgt etwa 200 mm.The inclined side legs 32 of the rain drainage channel 31 each end end carry an extruded profile 40 made of an aluminum alloy, the cross-section of which consists of an L-shaped condensate drain channel 41 and a subsequent clamping profile 42; the latter accommodates the area of a longitudinal edge 21 of the outer film 22 and a clamping strip 44 in an undercut groove 43. The clamping strip 44 ensures the fixing of the tensioned outer film 22 in the clamping profile 42 of the connecting profile 40. The horizontal distance s between two outer films 22 in FIG. 6 is approximately 200 mm.

Mit 46 ist eine Dämmatte bezeichnet, die sich an der Außenfläche des Seitenschenkels 32 von der Kondensatfangrinne 41 bis zu einem weiteren Anschlußprofil 48 erstreckt, welches winkelförmig gestaltet und an einer Kante des Bogenbinders 14 festgelegt sowie durch Schrauben 47 gesichert ist. Dieses Anschlußprofil 48 ist -- in seiner in Fig. 6 linken Ausführung -- mit zwei hinterschnittenen Nuten 49, 50 zum An­schluß der Mittel- und der Innenfolie 23, 24 sowie zur Aufnahme je­weils eines Klemmstreifens 44 ausgestattet.With 46 an insulation mat is designated, which extends on the outer surface of the side leg 32 from the condensate trap 41 to a further connection profile 48, which is angularly shaped and on an edge of the bow tie 14 is fixed and secured by screws 47. This connecting profile 48 is - in its left-hand embodiment in FIG. 6 - equipped with two undercut grooves 49, 50 for connecting the central and inner foils 23, 24 and for receiving a clamping strip 44 in each case.

Bei der anderen Ausführungsform der Fig. 6 (rechts) ist die Innen­folie 24 mit einem Kederrand 52 versehen, der in einer Kedernut 51 des Anschlußprofils 48 verläuft - dessen Höhe k₁ mißt etwa 70 mm und sein Abstand k₂ von der Oberkante des anderen Anschlußprofiles 40 etwa 80 mm.In the other embodiment of FIG. 6 (right), the inner film 24 is provided with a welt edge 52 which runs in a welt groove 51 of the connecting profile 48 - whose height k 1 measures approximately 70 mm and its distance k 2 from the upper edge of the other connecting profile 40 approximately 80 mm.

Die Außen- und die Innenfolie 22, 24 sind jeweils von etwa 190 µm Dicke, während die Mittelfolie 23 eine Dicke von etwa 100 µm aufweist. Die Mittelwerte der physikalischen Eigenschaften der verwendeten Folie für eine Foliendicke zwischen 90 und 150 µm sind der folgenden Tabelle zu entnehmen: Eigenschaft Einheit Wert Dichte g/cm³ 1,75+0,05 Reißfestigkeit längs N/mm² 40 - 50 quer 40 - 50 Reißdehnung längs % 300 - 400 Streckspannung längs N/mm² 20 - 30 quer 20 - 30 Dehnung a.d.

The average values of the physical properties of the film used for a film thickness between 90 and 150 µm can be found in the following table: property unit value density g / cm³ 1.75 + 0.05 Tensile strength along N / mm² 40-50 across 40-50 Elongation at break along % 300-400 Yield stress along N / mm² 20-30 across 20-30 Elongation to yield strength along % 15-20 across 15-20 Cold break temperature along ° C - 180 across - 180 Tear resistance with trapezoidal cut along N / mm 400-500 across 400-500

Fig. 7 zeigt eine Ausführung eines Kissens 27a, dessen äußere oder obere Luftkammer 25 eine stehende Luftfüllung mit Überdruck enthält, wohingegen die innere oder untere Luftkammer 26 von der Gebäudeinnenluft oder von Strömungsmittel aus einem Lufterwärmungssystem gemäß Pfeil x durchströmt wird. Das alternative Lufterwärmungssytem ist bei 54, die Ein- und Auslaßventile sind bei 56,58 angedeutet. Der Luftdruck in der unteren Luftkammer 26 von bevorzugt 2O mm WS kann durch das/die Auslaßventil/e 58 gesteuert werden.Fig. 7 shows an embodiment of a pillow 27 a , the outer or upper air chamber 25 contains a standing air filling with overpressure, whereas the inner or lower air chamber 26 is flowed through by the interior of the building or by fluid from an air heating system according to arrow x. The alternative air heating system is indicated at 54, the intake and exhaust valves at 56.58. The air pressure in the lower air chamber 26, preferably 20 mm WS, can be controlled by the exhaust valve (s) 58.

Ebenfalls verdeutlichen Fig. 8, 9 Kissenkonstruktionen 27b und 27c mit fließender Luft x in der unteren Luftkammer 26. Hier ist aber die obere Luftkammer 25 -- im Gegensatz zur vorstehend beschriebenen Ausführung 27a -- gemäß Fig. 8 durch ein Ventil 60 in der Mittelfolie 23 an die untere Luftkammer 26 angeschlossen, so daß ein Zweigstrom y des Strömungsmittels die obere Luftkammer 25 mit gesteuerter Luft befüllen kann. Mit 62 ist ein normalerweise geschlossenes oberes Anschlußventil in der Außenfolie 22 bezeichnet.8, 9 also illustrate pillow constructions 27 b and 27 c with flowing air x in the lower air chamber 26. Here, in contrast to the embodiment 27 a described above, the upper air chamber 25 is shown in FIG. 8 by a valve 60 in the middle film 23 connected to the lower air chamber 26 so that a branch flow y of the fluid can fill the upper air chamber 25 with controlled air. 62 with a normally closed upper connection valve in the outer film 22 is designated.

Zusätzlich zur ziehenden Luft x oder stattdessen kann an der bodenwärts gerichteten Oberfläche 24a der Innenfolie 24 ein bei 54a angewärmter Oberflächenluftstrom z -- aus Blasdüsen 55 kommend -- entlanggeführt werden.In addition to the drawing air x or instead, a surface air flow z heated from 54 a - coming from blowing nozzles 55 - can be guided along the bottom-facing surface 24 a of the inner film 24.

Fig. 9 gibt an der Stelle des beschriebenen Ventils 60 einen Membranendurchbruch 64 wieder. Außerdem ist an dem hier gezeigten Binder 14, der entsprechend Fig. 10 -- nicht bei einem Kalottendach -- parallel zu einem weiteren Binder 14 ein gestrecktes rechteckiges Kissenfeld begrenzt, rechts ein auf der linken Binderseite nur angedeutetes Paar von Anschlußprofilen 66,68 zu erkennen, dessen oberen Anschlußprofil 66 beidseits einer Knicklinie 67 hinterschnit­ tene Nuten 43,49 aufweist. Das untere Anschlußprofil 68 sitzt unter Zwischenschaltung von Dichtungsstreifen 69 auf dem Binder 14 auf und hält in seiner abwärts gerichteten Nut 51 die Innenfolie 24.9 shows a membrane opening 64 at the location of the valve 60 described. In addition, on the binder 14 shown here, which according to FIG. 10 - not with a calotte roof - has an elongated rectangular cushion field parallel to a further binder 14, on the right a pair of connecting profiles 66, 68, only indicated on the left side of the binder, can be seen , whose upper connection profile 66 undercuts on both sides of a crease line 67 has grooves 43,49. The lower connection profile 68 is seated on the binder 14 with the interposition of sealing strips 69 and holds the inner film 24 in its downward groove 51.

Die Fig. 1O zeigt zudem, daß die Anschlußprofile 68 -- aber auch 4O,48,66 -- auch an den Stirnenden der Kissenfelder angebracht sind, denen auch die Einlaßventile 56 und die Auslaßventile 58 zugeordnet sind; diese Ventile 56,58 bzw. 60,62 können entweder beidseits eines Querschnitts nach Fig. 5,7,8 oder auch an den Stirnenden langer Kissenfelder nach Fig. 3,10 vorgesehen werden.1O also shows that the connecting profiles 68 - but also 40, 48, 66 - are also attached to the ends of the pillow fields, to which the inlet valves 56 and the outlet valves 58 are also assigned; these valves 56, 58 and 60, 62 can either be provided on both sides of a cross section according to FIGS. 5, 7, 8 or also at the ends of long pillow fields according to FIGS. 3, 10.
