Description

Die Erfindung bezieht sich auf eine vorgehängte, vorzugsweise auf einer Aluminium-Unterkonstruktion montierte Fassadenkonstruktion nach dem Oberbegriff des Anspruchs 1.The invention relates to a curtain, preferably one Aluminum substructure assembled facade construction according to the generic term of claim 1.

Aus der DE-A-34 01 271 ist eine Fassade bekannt deren Fassadenplatten aus einem vorderen und hinteren Plattenteil bestehen, die durch Stege miteinander verbunden sind. Außerdem sind die Platten an der hinteren Seite mit einem Kopf- und einem Fußfalz versehen, die in dem an der Wand montierten Zustand untereinander angeordnet sind und zum Zwecke der Befestigung von dem H-förmigen Teil ein oder mehrerer Plattenhalter umgriffen werden. Desweiteren sind die Fassadenplatten an der vorderseitigen Unterkante mit einem Tropffalz versehen, der im montierten Zustand den Kopffalz der darunter angeordneten Platte so übergreift, daß die Vorderflächen der oberen und der unteren Fassadenplatten in einer Ebene liegen. Dabei werden der Kopffalz der unteren Fassadenplatten und die Plattenhalter von den Tropffalz der oberen Fassadenplatte so überdeckt, daß diese nur teilweise sichtbar sind.From DE-A-34 01 271 a facade is known whose facade panels consist of a front and rear plate part, which by webs are interconnected. In addition, the plates are on the rear Side with a head and foot fold, the one on the wall assembled state are arranged one below the other and for the purpose of Attachment encompassed by the H-shaped part of one or more plate holders become. Furthermore, the facade panels are on the front Provide the lower edge with a drip fold, which in the assembled state Top fold of the plate arranged below engages so that the front surfaces the upper and lower facade panels lie in one plane. The top rebate of the lower facade panels and the panel holders covered by the drip fold of the upper facade panel so that it are only partially visible.

Die Nachteile dieser Konstruktion liegen darin, daß die Wasserführung von der Rückseite zur Vorderseite der Fassade mangelhaft ist. Da die Rückseite der Fußfalze der oberen Platten und die Rückseite der Kopffalze der unteren Platten in einer Ebene liegen, wird das an der Rückseite der oberen Fassadenplatten ablaufende Kondensat oder vom Wind durch die offenen Horizontalfugen eingetriebenes Fassadenwasser nicht zwangsläufig und restlos zur Vorderseite der Fassade abgeleitet sondern läuft zu einem großen Teil auf der Rückseite der jeweils darunter angeordneten Fassadenplatten weiter. In regen- und windreichen Regionen kann es dadurch zu einer übergroßen Wasserbelastung an der Rückseite der Fassade kommen, so daß die Gefahren der kapillaren Übertragung von Wasser auf die Tragprofile und von dort auf die Wärmedämmung und zur Durchfeuchtung derselben kommen kann.The disadvantages of this construction are that the water flow from the back to the front of the facade is poor. Because the back the rebate of the top panels and the back of the top rebate of the bottom panels Plates lying in one plane will be at the back of the top Condensate draining off facade panels or from the wind through the open Horizontal joints of facade water not necessarily and completely derived to the front of the facade but runs to a large one Part on the back of the facade panels arranged below further. In rainy and windy regions, this can result in one oversized water pollution coming at the back of the facade, so that the dangers of capillary transfer of water to the support profiles and from there to the thermal insulation and to moisten it can come.

Ein weiterer Nachteil liegt darin begründet, daß diese bekannten Fassadenplatten nur so montiert werden können, daß die Vorderseiten der jeweils oberen und unteren Fassadenplatten in einer Ebene liegen. Eine schindelartige Überdeckung der oberen über die unteren Fassadenplatten ist aus architektonisch-ästhetischen Gründen nicht möglich, da die Platten dafür zu dick sind.Another disadvantage lies in the fact that these known facade panels can only be mounted so that the front of each upper and lower facade panels lie in one plane. A shingle-like Coverage of the upper and lower facade panels is off Architectural-aesthetic reasons not possible because the panels are too are fat.

Nachteilig ist an dieser Fassadenkonstruktion auch. daß die Plattenhalter durch den Tropffalz nur teilweise verdeckt werden und deshalb sichtbar sind, was besonders bei hellen Platten auffällig und unerwünscht ist.Another disadvantage of this facade construction. that the plate holder only partially covered by the drip fold and therefore visible are what is particularly noticeable and undesirable in light panels.

In der Baupraxis sind auch Fassadenkonstruktionen allgemein gebräuchlich, bei welchen sich dünne Fassadenplatten in Zweifach- oder Dreifachdeckung schindelförmig überlappen, wobei der untere Rand der jeweils oberen Platten durch einen gekröpften Halter aus Draht umgriffen wird. Die Nachteile dieser Konstruktion liegen darin, daß bei der Dreifachdeckung praktisch kein Belüftungsspalt zwischen den Fassadenplatten angeordnet ist und wegen der flächigen Auflage der einzelnen Gebinde aufeinander auch keine sichere Wasserführung von der Rückseite zur Vorderseite der Fassade gewährleistet ist. Durch den direkten Kontakt zwischen Fassadenplatte und Traglatte kann bei der Dreifachdeckung das rückseitig ablaufende Wasser oder Kondensat sogar auf die Traglatte und über diese in die Wärmedämmung abgeleitet werden. Die Folgen der mangelnden Belüftung und Wasserführung sind die Durchfeuchtung der Unterkonstruktion und der Wärmedämmung und dadurch verursachte Bauschäden.In construction practice, facade constructions are also common, where there are thin facade panels in double or triple covering Overlap like a shingle, with the lower edge of each of the top plates is gripped by a cranked wire holder. The disadvantages this construction is that practical with triple coverage no ventilation gap is arranged between the facade panels and because the flat support of the individual containers on each other also none ensures safe water flow from the back to the front of the facade is. Due to the direct contact between the facade panel and With the triple cover, the water draining from the back can be a truss or condensate even on the support batten and via this into the thermal insulation be derived. The consequences of the lack of ventilation and water flow are the moistening of the substructure and the thermal insulation and construction damage caused thereby.

Weitere Nachteile dieser Schindelfassaden in Zweifach- oder Dreifachdeckung liegen darin, daß die Fassadenplatten relativ dünn und deshalb schlagempfindlich sind und daß der obere Plattenrand durch die Klemmwirkung der Plattenhalter zusätzlich auf Bruch beansprucht wird.Further disadvantages of these shingle facades in double or triple cover lie in the fact that the facade panels are relatively thin and therefore sensitive to impact are and that the upper edge of the plate by the clamping action of Plate holder is additionally subjected to breakage.

Ein wesentlicher Nachteil ist auch darin begründet, daß die den unteren Plattenrand umgreifenden Plattenhalter weder ganz noch teilweise verdeckt ausgeführt werden können und somit das Erscheinungsbild der Fassade erheblich beeinträchtigen. A major disadvantage is also due to the fact that the lower Plate holder encompassing the edge of the plate neither completely nor partially can be executed and thus the appearance of the facade significantly affect.

Sehr schwierig ist bei diesen Fassaden auch das Auswechseln einzelner beschädigter Platten. Die neu zu montierende Fassadenplatte muß dabei nicht nur von unter in den engen Spalt eingeschoben werden. Dabei erfordert aber der Plattenhalter, in welcher die Fassadenplatte mit ihrem unteren Rand eingehoben werden muß, beim Einschieben eine wesentlich geringere Neigung der Platte, so daß der untere Rand der darüber angeordneten Fassadenplatten unter Vorspannung von der Fassade abgehoben werden muß, um den an sich parallelen Spalt soweit konisch zu erweitern, daß die neue Platte eingeschoben werden kann. Da Schindelfassaden zur Vermeidung von Klappergeräuschen bei Wind mit vorgespannten Haltern montiert werden, ist das Auswechseln von einzelnen Platten oft sehr schwierig und häufig auch mit dem Bruch der neuen Fassadenplatten durch die zusätzliche Beanspruchung beim Einschieben verbunden.With these facades it is also very difficult to replace individual ones damaged plates. The newly installed facade panel must be not just be pushed into the narrow gap from below. Requires but the plate holder, in which the facade plate with its lower Edge must be lifted when inserting a much smaller Tilt the plate so that the lower edge of the one above it Façade panels are lifted off the facade under pre-tension must, in order to expand the parallel gap so far conically that the new plate can be inserted. Because shingle facades to avoid of rattling noises in the wind with pre-tensioned brackets, the exchange of individual plates is often very difficult and often with the breakage of the new facade panels due to the additional Stress associated with insertion.

Aufgabe der Erfindung ist es deshalb, eine Fassadenkonstruktion zu beschreiben, bei welcher dicke Fassadenplatten mit schindelartiger Überlappung verdeckt werden, gleichzeitig aber die oben beschriebenen Nachteile der mangelhaften Wasserführung und Durchlüftung zu vermeiden, die Plattenhalter unsichtbar anzuordnen und die Möglichkeit des Auswechselns einzelner beschädigter Fassadenplatten zu erleichtern.The object of the invention is therefore to describe a facade construction, in which thick facade panels with shingle-like overlap are concealed, but at the same time the disadvantages described above to avoid the poor water supply and ventilation, the plate holder arrange invisible and the possibility of replacement to facilitate individual damaged facade panels.

Die Lösung der gestellten Aufgabe erfolgt erfindungsgemäß durch die Kennzeichen des Anspruchs 1. Der Vorteil dieser Ausführungsform liegt darin. daß relativ dicke Fassadenplatten, vorzugsweise Fassadenplatten mit horizontalen oder vertikalen Löchern, mit einem Tropffalz und Fußfalz am unteren Rand und einem Kopffalz am oberen Rand schindelartig überdeckend so montiert werden können, daß im fertigen Zustand der optische Eindruck entsteht, es handle sich um relativ dünne Fassadenplatten, die in 2-facher oder 3-facher Überdeckung verlegt sind. Dieser Eindruck entsteht dadurch. daß von der Außenseite der Fassade her gesehen nur die Stärke des Tropffalzes und die Tiefe des Lüftungsschlitzes sichtbar ist (Fig. 1). Ein weiterer Vorteil dieser Ausführungsform liegt darin, daß das an der Rückseite der oberen Fassadenplatte ablaufende Kondensat oder vom Wind eingetriebenes Fassadenwasser vollständig auf die Vorderseite des Kopffalzes der unteren Platte und damit zur Fassadenvorderseite abgeleitet wird. Dadurch wird gewährleistet, daß sowohl die Unterkonstruktion als auch die Wärmedämmung und die Gebäudewand trocken bleiben und keine Bauschäden entstehen. Außerdem ergibt sich durch die Anordnung eines Lüftungsspaltes zwischen der Rückseite des Tropffalzes und der Vorderseite des Kopffalzes die aus bauphysikalischen Gründen erforderliche Möglichkeit die gesamte Fassadenfläche zu be- und entlüften um Feuchtigkeit aus dem Gebäudeinneren abzuführen. Auch dies ist zur Vermeidung von Bauschäden erforderlich. Durch die Ausbildung der Plattenhalter nach Anspruch 2 mit einem U-förmigen Teil, welcher den Fußfalz der oberen Fassadenplatte von unten her umgreift, wird die Tiefe des Lüftungsspaltes und die Höhenlage der oberen Fassadenplatte und somit das Haß der Höhenüberdeckung definiert.According to the invention, the object is achieved by the indicators of claim 1. The advantage of this embodiment is that. that relatively thick facade panels, preferably facade panels with horizontal or vertical holes, with a drip fold and foot fold at the bottom Edge and a top fold at the upper edge covering like a shingle can be assembled that in the finished state the visual impression arises, it is a question of relatively thin facade panels, which are divided into two or triple cover is installed. This creates this impression. that seen from the outside of the facade only the strength of the drip fold and the depth of the ventilation slot is visible (Fig. 1). Another Advantage of this embodiment is that it is on the back condensate draining from the top facade panel or wind-driven condensate Facade water completely on the front of the top rebate of the bottom Plate and thus to the front of the facade is derived. This will ensures that both the substructure and the thermal insulation and the building wall remains dry and there is no damage to the building. In addition, the arrangement of a ventilation gap between the back of the drip fold and the front of the head fold possibility of building physics required the entire facade area to ventilate to remove moisture from inside the building. This is also necessary to avoid structural damage. Through the Forming the plate holder according to claim 2 with a U-shaped part, which encompasses the rebate of the upper facade panel from below, the depth of the ventilation gap and the height of the upper facade panel and thus defines the hatred of height coverage.

Durch die Ausbildung der Plattenhalter nach Anspruch 2 (Fig. Z) ist es möglich, das Maß der vertikalen Überdeckung des Tropffalzes der oberen Fassadenplatte über den oberen Randbereich der unteren Fassadenplatte und die Tiefe des horizontalen Lüftungsspaltes zu variieren. Dazu muß lediglich das nach oben offene U-förmige Teil des Plattenhalters gegenüber dem nach unter offenen U-förmigen Teil stärker oder weniger stark nach unten versetzt angeordnet werden. Der Vorteil, der sich daraus ergibt, ist eine Vergrößerung oder Verkleinerung der Spalthöhe des horizontalen Teils des Lüftungsspaltes. Außerdem ist es möglich, die Tiefe des vertikalen Lüftungsspaltes zwischen der Rückseite des Tropffalzes und der Vorderfläche des Kopffalzes dadurch zu variieren, daß der horizontale Versatz der beiden U-förmigen Teile des Plattenhalters variiert wird. Das beinhaltet den Vorteil, sowohl den vorderen Teil des Luftspaltes zwischen Fußfalz und Plattenvorderfläche als auch den hinteren Teil des Luftspaltes zwischen der Rückseite der oberen Fassadenplatte und der Vorderseite des Kopffalzes der unteren Fassadenplatte in ihrer Tiefe variieren und den bauphysikalischen Erfordernissen anpassen zu können. Da die Plattenhalter von der Fassadenvorderseite her gesehen nur eine geringe Breite haben, ist der zwischen den Plattenhaltern angeordnete Lüftungsquerschnitt in erster Linie von der Tiefe des vorderen und hinteren Lüftungsspaltes und von der Höhe des horizontalen Teiles des mittleren Lüftungsspaltes abhängig. Da die beiden U-förmigen Teile des Plattenhalters sowohl den Fußfalz der oberen als auch den Kopffalz der unteren Fassadenplatte mit Spiel umgreifen, werden keinerlei Zwängungen auf die Falze ausgeübt. Dies hat den Vorteil, daß die Bruchgefahr für die Falze bei zusätzlicher Stoßbeanspruchung von vorne gering ist. Ein weiterer wesentlicher Vorteil der erfindungsgemäßen Fassadenkonstruktion ist die einfache Austauschbarkeit einzelner beschädigter Fassadenplatten. Die auszutauschende Fassadenplatte muß dabei lediglich von unten her mit dem Kopffalz in das diesen von oben her übergreifende U-förmige Teil des Plattenhalters eingeschoben werden, ohne daß dabei die oberen Platten oder die Plattenhalter berührt oder gar angehoben und gelockert werden müßten. Es muß lediglich an den Stellen, in welchen die U-förmigen Teile des Halters den Kopffalz der einzusetzenden Platte übergreifen, die Höhe des Kopffalzes um einige Millimeter soweit reduziert werden, daß diese Fassadenplatte um einige Millimeter höher so weit angehoben werden kann, daß ihr Fußfalz über den niederen vorderen Flansch des nach oben offenen U-förmigen Teiles des Plattenhalters eingehoben werden kann. Gegen unbefugtes Wiederausheben der ausgetauschten Fassadenplatte wird diese dadurch gesichert, daß das den Kopffalz von oben her umgreifende U-förmige Teil des Plattenhalters mit einer zunächst plastischen und dann aushärtenden Masse gefüllt wird. Ein weiterer Vorteil der erfindungsgemäßen Passadenkonstruktion gegenüber dem Stand der Technik ist die Tatsache, daß die Plattenhalter vollständig unsichtbar angeordnet sind und weder aus dem horizontalen Blickwinkel noch bei schrägem Blick nach oben sichtbar sind.By forming the plate holder according to claim 2 (Fig. Z) it is possible the degree of vertical coverage of the drip fold of the upper one Facade panel over the upper edge area of the lower facade panel and to vary the depth of the horizontal ventilation gap. To do this only opposite the upwardly open U-shaped part of the plate holder more or less after the open U-shaped part staggered below. The advantage that results from this is an increase or decrease in the gap height of the horizontal part of the ventilation gap. It is also possible to change the depth of the vertical Ventilation gap between the back of the drip fold and the front surface to vary the top fold in that the horizontal offset of the two U-shaped parts of the plate holder is varied. This contains the advantage of both the front part of the air gap between the foot fold and Plate front surface as well as the rear part of the air gap between the Back of the upper facade panel and the front of the top fold of the lower facade panel vary in depth and the building physics To be able to adapt to requirements. Since the plate holder from the front of the facade seen only a small width, is that between the ventilation cross section arranged primarily from the Depth of the front and rear ventilation gap and the height of the depending on the horizontal part of the middle ventilation gap. Since the two U-shaped parts of the plate holder both the rebate of the top as well grasp the top rebate of the lower facade panel with play, none at all Squeezes exerted on the folds. This has the advantage that the risk of breakage low for the folds with additional impact loads from the front is. Another significant advantage of the facade construction according to the invention is the simple interchangeability of individual damaged facade panels. The facade panel to be replaced only has to be from below forth with the top fold into the U-shaped overlapping it from above Part of the plate holder can be inserted without the upper Plates or the plate holder touched or even raised and loosened should be. It only needs to be in the places where the U-shaped Parts of the holder overlap the top fold of the plate to be inserted Height of the top fold can be reduced by a few millimeters so that this Facade panel can be raised a few millimeters higher as far that her foot fold over the lower front flange of the open top U-shaped part of the plate holder can be lifted. Against unauthorized persons This will remove the replaced facade panel ensured that the top fold encompassing the U-shaped from above Part of the plate holder with an initially plastic and then hardening Mass is filled. Another advantage of the facade construction according to the invention compared to the prior art is the fact that the plate holders are arranged completely invisible and neither from the horizontal viewing angles are still visible when looking up at an angle.

Bei einer anderen Ausführungsart der erfindungsgemäßen Fassadenkosntruktion (Fig. 2) ist der horizontale Versatz des den Fußfalz der oberen Fassadenplatte umgreifenden U-förmigen Teiles des Plattenhalters vor dem den Kopffalz der unteren Fassade umgreifenden U-förmigen Teil wesentlich größer, als dies in Fig. 1 dargestellt ist. Dies ist dadurch möglich, daß zwischen beiden U-förmigen Teilen ein Abstandssteg angeordnet ist. Der Vorteil dieser Konstruktion liegt darin, daß die Fassadenplatten mit einem wesentlich stärkeren und damit bruchsichereren Tropffalz als in Fig. 1 dargestellt ausgestattet sein können, gleichwohl aber die gleiche Tiefe des zwischen Tropffalz der oberen Platte und Vorderfläche der unteren Platte angeordnete Lüftungsspalt beibehalten werden kann. Ein weiterer Vorteil besteht darin, daß auch die Tiefe dieses Lüftungsspaltes zusätzlich vergrößert werden kann. Durch den besonders breiten vertikalen Lüftungsspalt vor dem Kopffalz der unteren Fassadenplatte ist auch eine besonders sichere Wasserführung von der Rückseite der oberen zur Vorderseite der unteren Platte gewährleistet.In another embodiment of the facade construction according to the invention (Fig. 2) is the horizontal offset of the foot fold of the top Facade panel encompassing the U-shaped part of the panel holder in front of the the U-shaped part encompassing the top fold of the lower facade larger than that shown in Fig. 1. This is possible because a spacer is arranged between the two U-shaped parts. The The advantage of this design is that the facade panels with one much stronger and therefore shatterproof drip fold than in Fig. 1 can be equipped, but still the same depth of the between the drip fold of the upper plate and the front surface of the lower plate arranged ventilation gap can be maintained. Another advantage is that the depth of this ventilation gap is also increased can be. Due to the particularly wide vertical ventilation gap in front of the top rebate of the lower facade panel is also a particularly secure one Water flow from the back of the upper to the front of the lower Plate guaranteed.

Bei weiteren Ausführungsvarianten (Fig. 3a und 3b) sind die Fassadenplatten ohne Kopffalz ausgeführt. Dies ist zwar mit dem Nachteil einer schlechteren Wasserführung von der Rückseite zur Vorderseite hin verbunden, hat aber den Vorteil, daß die Herstellung insbesondere keramischer Fassadenplatten ohne Kopffalz etwas einfacher ist. Insbesondere kann aber die Fassadenplatte am oberen Rand zum Zwecke der vertikalen Maßanpassung bei der Montage beliebig zugeschnitten werden, ohne daß sich ihre Gesamtstärke ändert, so daß das die unteren Fassadenplatten von ober her übergreifende U-förmige Teil des Plattenhalters immer die der Plattenstärke angepaßte. genau richtige lichte Tiefe aufweist. Diese Variante ohne Kopffalz ist insbesondere für regen- und windarme Klimagebiete geeignet. Bei am oberen Rand angeschnittenen Fassadenplatten kann das rückseitig ablaufende Kondensat oder Wasser zum seitlichen Plattenende in die Vertikalfuge abgeleitet werden.In other design variants (Fig. 3a and 3b) are the facade panels executed without top fold. While this has the disadvantage of being worse Water supply connected from the back to the front but the advantage that the production of ceramic facade panels in particular is a bit easier without a top fold. In particular, however, the facade panel at the top for the purpose of vertical adjustment at the Assembly can be cut as desired without losing their overall strength changes, so that the lower facade panels from above U-shaped part of the plate holder always that adapted to the plate thickness. has just the right clear depth. This variant is without top fold Particularly suitable for low-rain and windless climates. At the top Facade panels cut on the edge can be the condensate draining from the rear or water is drained into the vertical joint to the side of the board become.

Bei einer anderen vorteilhaften Ausführungsform (Fig. 4a) der erfindungsgemäßen Fassadenkonstruktion wird der Kopffalz oder der obere Rand der unteren Fassadenplatte nicht durch ein U-förmiges nach unten offenes Teil des Plattenhalters umgriffen, sondern lediglich durch einen einzelnen Plansch hintergriffen. Durch diesen Flansch wird die Fassadenplatte nach hinten abgestützt, so daß der zur Durchlüftung erforderliche Spalt zwischen der Rückseite des Kopffalzes bzw. der Fassadenplatten und der Vorderkante des horizontalen Profiles offen gehalten wird. Die horizontale Bewegung des oberen Randes der Platten zur Fassadenvorderseite hin kann durch geeignete Abstandshalter zwischen den Fassadenplatten verhindert werden. Der Vorteil dieser Variante besteht darin, daß die Plattenhalter eine noch etwas einfachere Form besitzen. In another advantageous embodiment (FIG. 4a) of the invention Facade construction is the top rebate or the top of the lower facade panel not by a U-shaped part open at the bottom of the plate holder, but only by a single one Dodging behind. With this flange, the facade panel becomes supported at the rear, so that the gap required for ventilation between the back of the top rebate or the facade panels and the front edge the horizontal profile is kept open. The horizontal Movement of the upper edge of the panels towards the front of the facade can prevented by suitable spacers between the facade panels become. The advantage of this variant is that the plate holder have an even simpler shape.

Bei einer weitern Ausführungsvariante (Fig. 5a, 5b oder 5c) stützt sich der Kopffalz bzw. die hinter Oberkante der unteren Fassadenplatte direkt und ohne Abstand an einem horizontalen oder vertikalen Profil der Unterkonstruktion ab. Dabei wird der Kopffalz oder der obere Plattenrand der unteren Platte gegen Kippen zur Fassadenvorderseite hin durch eine Flansch des Plattenhalters gesichert, der von oben her vor die Oberkante der unteren Fassadenplatte oder deren Kopffalz greift. Der Vorteil dieser Konstruktion ohne Luftspalt zwischen dem Kopffalz oder Kopf der Fassadenplatte und der Unterkonstruktion liegt in der besonders einfachen Ausführungsform der Plattenhalter und in der geringeren Bautiefe der gesamten Fassadenkonstruktion.In a further embodiment variant (Fig. 5a, 5b or 5c) is supported the top rebate or the rear edge of the lower facade panel directly and without space on a horizontal or vertical profile of the substructure from. The top fold or the top edge of the plate becomes the bottom Panel against tipping to the front of the facade through a flange of the plate holder, which from above in front of the upper edge of the lower Facade panel or its top rebate engages. The advantage of this construction without an air gap between the head rebate or head of the facade panel and the substructure lies in the particularly simple embodiment the plate holder and in the shallower depth of the entire facade construction.

Bei einer anderen Art der erfindungsgemäßen Fassadenkonstruktion nach dem Kennzeichen des Anspruchs 7 greift ein nach oben gerichteter Flansch des Plattenhalters in die Nut zwischen Tropffalz und Fußfalz der Fassadenplatte ein (Fig. 6), welche zum Zweck der horizontalen Fixierung des Plattenfußes entsprechend schmal ausgeführt ist. In dieser Ausführungsart kann der hintere Flansch des U-förmigen nach oben offenen Teiles des Plattenhalters nach den Ansprüchen 2 bis 6 entfallen. Alle anderen Details der Fassadenkonstruktion nach den Ansprüchen 3 bis 6 können auch mit der eben beschriebenen Ausführungsart nach Anspruch 7 kombiniert werden. Der Vorteil dieser Ausführungsart besteht darin, daß die schmale Nut zwischen Tropffalz und Fußfalz auch in besonders einfacher Weise gesägt oder gefräst werden kann.In another type of facade construction according to the invention the characteristic of claim 7 engages an upward flange the plate holder into the groove between the drip rebate and the foot rebate of the facade panel a (Fig. 6), which for the purpose of horizontal fixation of the plate foot is designed accordingly narrow. In this embodiment can the rear flange of the U-shaped part open to the top Plate holder according to claims 2 to 6 omitted. All other details the facade construction according to claims 3 to 6 can also with the embodiment just described can be combined according to claim 7. The advantage of this embodiment is that the narrow groove sawn in a particularly simple manner between drip fold and foot fold or can be milled.

Die Fig. 1 zeigt eine vertikale Unterkonstruktion 1 mit einem horizontalen Profil 2 und eine Fassadenplatte 3 mit einem Kopffalz 4 am oberen Plattenrand 5 und mit einem Tropffalz 6 und einem Fußfalz 7 am unteren Plattenrand 8, welche mittels eines Plattenhalters 9 an dem horizontalen Profil 2 befestigt ist. Dabei übergreift der Tropffalz 6 der oberen Fassadenplatte 10 die Vorderfläche 11 des oberen Plattenrandes 5 der unteren Fassadenplatte 12 so, daß die Vorderfläche 13 der oberen Fassadenplatte 10 im Bereich des Tropffalzes 6 um das Maß der Tropffalzstärke plus der Tiefe des vorderen Lüftungsspaltes 14 vor der Vorderlfäche 11 des oberen Plattenrandes 5 der unteren Fassadenplatte 12 angeordnet ist. Das nach oben offene U-förmige Teil 15 des Plattenhalters 9 umgreift den Fußfalz 4 der oberen Fassadenplatte 10 von unten her und das nach unten offene U-förmige Teil 17 umgreift den Kopffalz 4 der unteren Fassadenplatte 12 von oben her. Der Verbindungssteg 21 des nach oben offenen U-förmigen Teiles 15 ist gegenüber dem Verbindungssteg 22 des nach unten offenen U-förmigen Teiles 17 des Plattenhalters 9 sowohl in der Höhe als auch in der Tiefe der Fassade versetzt angeordnet. Dabei ist in Fig 1 der vordere Schenkel 26 des U-förmigen Teiles 17 identisch mit dem hinteren Schenkel 26 des U-förmigen Teiles 15. Kondensat oder eingedrungenes Fassadenwasser, welches an der Rückseite 18 der oberen Fassadenplatte 10 abläuft, wird in dem vertikalen hinteren Lüftungsspalt 19 vor dem Kopffalz 4 der unteren Fassadenplatte 12 abgeleitet und fließt somit zwangsläufig durch den horizontalen Lüftungsspalt 20 und den vorderen vertikalen Lüftungsspalt 14 zur Vorderfläche 11 der unteren Fassadenplatte 12 ab. Dadurch ist gewährleistet, daß sowohl das horizontale Profil 2. die Unterkonstruktion 1 als auch die zwischen dieser angeordnete Wärmedämmung 23 trocken bleibt. Die Be- und Entlüftung des hinter den Fassadenplatten angeordneten Luftraumes erfolgt durch die offenen Lüftungsspalte 14, 20 und 19 zwischen den (in Zeichnungsebene hintereinander) angeordeten Plattenhaltern 9. Ein weiterer Lüftungsspalt 24 zwischen der Rückseite der Fassadenplatte 12 und der Vorderkante 25 des horizontalen Profils 2 dient auch zur kapillaren Trennung der Rückseite der Fassadenplatte 12 von dem horizontalen Profil 2.Fig. 1 shows a vertical substructure 1 with a horizontal Profile 2 and a facade panel 3 with a top rebate 4 at the top of the panel 5 and with a drip fold 6 and a foot fold 7 at the lower edge of the plate 8, which by means of a plate holder 9 on the horizontal profile 2nd is attached. The overlap 6 overlaps the upper facade panel 10 the front surface 11 of the upper panel edge 5 of the lower facade panel 12 so that the front surface 13 of the upper facade panel 10 in the area of the drip fold 6 by the measure of the drip fold thickness plus the depth of the front one Ventilation gap 14 in front of the front surface 11 of the upper plate edge 5 the lower facade panel 12 is arranged. The open U-shaped Part 15 of the plate holder 9 engages around the foot rebate 4 of the upper facade plate 10 from below and the U-shaped part 17, which is open at the bottom grips the top rebate 4 of the lower facade panel 12 from above. The Connecting web 21 of the upwardly open U-shaped part 15 is opposite the connecting web 22 of the downwardly open U-shaped part 17th of the plate holder 9 both in the height and in the depth of the facade staggered. 1 is the front leg 26 of the U-shaped one Part 17 identical to the rear leg 26 of the U-shaped Part 15. Condensate or penetrated facade water, which at the Back 18 of the upper facade panel 10 expires in the vertical rear ventilation gap 19 in front of the top rebate 4 of the lower facade panel 12 derived and thus inevitably flows through the horizontal ventilation gap 20 and the front vertical ventilation gap 14 to the front surface 11 the lower facade panel 12. This ensures that both the horizontal profile 2. the substructure 1 and between this arranged thermal insulation 23 remains dry. The ventilation of the air space arranged behind the facade panels takes place through the open ventilation gaps 14, 20 and 19 between the (in the drawing level one behind the other) arranged plate holders 9. Another ventilation gap 24 between the back of the facade panel 12 and the front edge 25 of the horizontal profile 2 also serves for capillary separation of the back of the Facade panel 12 from the horizontal profile 2.

Fig. 2 zeigt eine andere Ausführungsform, bei welcher das den Fußfalz 27 der oberen Fassadenplatte 28 umgreifende U-förmige Teil 29 weiter zur Fassadenvorderseite versetzt ist. Zwischen dem U-förmige Teil 29 und dem den Kopffalz 30 der untere Fassadenplatte 31 umgreifende U-förmigen Teil 32 ist ein Abstandssteg 33 angeordnet. Dadurch ist die Anordnung eines besonders dicken und dadurch bruchsicheren Tropffalzes 34 an der oberen Fassadenplatte 28 möglich. Auch der Lüftungsspalt 35 ist dadurch in Fig. 2 tiefer als in Fig. 1.2 shows another embodiment in which the foot fold 27 the upper facade panel 28 encompassing U-shaped part 29 further to Front of the facade is offset. Between the U-shaped part 29 and the the top fold 30 of the lower facade panel 31 embracing U-shaped part 32, a spacer web 33 is arranged. This makes the arrangement one particularly thick and therefore unbreakable drip fold 34 on the upper Facade panel 28 possible. As a result, the ventilation gap 35 is also shown in FIG. 2 deeper than in FIG. 1.

Fig. 3a zeigt eine Ausführungsform mit Fassadenplatten 41 ohne Kopffalz. Dabei ist das nach oben offenen U-förmige Teil 37 des Plattenhalters 38 gegenüber dem nach unten offenen U-förmigen Teil 39, welches den oberen Rand 40 umgreift, in Richtung der Tiefe der Fassadenkonstruktion versetzt angeordnet.Fig. 3a shows an embodiment with facade panels 41 without top fold.
