Abstract

The facade comprises a support structure (1), horizontal or vertical profiled sections (2), facade plates (3) and plate holders (4). The plate holders are mounted central relative to the vertical gaps (10,11) between the facade plates and are designed to engage by one or more tongues (7-9) into the vertical gaps. The centre axes of the tongues are set in the same vertical plane seen from the front of the facade. One or more tongues can engage in one or more swages (15,16) of vertical gap sections (17,18) which fit in the gaps.

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 Preamble of claim 1.

Aus der DE-A-34 01 271 und aus Herstellerprospekten ist eine Fassadenkonstruktion bekannt deren Platten mittels schmaler Plattenhalter an horizontalen oder vertikalen Tragprofilen befestigt werden. Dabei umgreift ein H-förmiges Teil des Plattenhalters den Kopffalz der jeweils unteren Platte und den Fußfalz der jeweils oberen Platte. Die Plattenhalter sind in der Regel bei den vorzugsweise im Querformat ausgeführten Fassadenplatten am Kopf- bzw. Fußfalz paarweise angeordnet und von den Ecken der Fassadenplatten her etwas eingerückt, so daß die Fassadenplatten an 4 Punkten befestigt sind. Da die H-förmigen Teile der Plattenhalter nach oben und unten wirksam sind, ergibt sich in der Fläche ein Bedarf von zwei Plattenhaltem pro Fassadenplatte. Der Nachteil dieser Konstruktion liegt in dem hohen Bedarf von zwei Plattenhaltern pro Fassadenplatte, wodurch sich sowohl die Materialals auch die Lohnkosten der fix und fertig montierten Fassadenkonstruktion erhöhen. Außerdem ist insbesondere der hohe Kopffalz einer erheblichen Bruchgefahr ausgesetzt, wenn ein starker Stoß von vorne auf die Fassadenplatte ausgeführt wird, da sich dabei durch leichtes Kippen der Fassadenplatte der Kopffalz mit seiner oberen hinteren Kante am Plattenhalter abstützt, so daß die Abstützkraft mit einem langen Hebelarm am Kopffalz wirksam wird.From DE-A-34 01 271 and from manufacturer's brochures is one Facade construction known whose slabs by means of narrow slab holders horizontal or vertical support profiles. It embraces H-shaped part of the plate holder the top fold of each lower plate and the rebate of the top plate. The plate holders are usually included the facade panels, preferably in landscape format, on the head or foot rebate arranged in pairs and from the corners of the facade panels here indented so that the facade panels are attached at 4 points. Since the H-shaped parts of the plate holders are effective upwards and downwards, there is a need for two plate holders per area Facade panel. The disadvantage of this construction is the high demand of two plate holders per facade plate, which means that both the material and also the labor costs of the fully assembled facade construction increase. In addition, the high head fold is particularly significant Risk of breakage if a strong impact hits the front Facade slab is executed, as this can be done by slightly tilting the Facade panel of the top rebate with its upper rear edge on the panel holder supports, so that the support force with a long lever arm on the top fold takes effect.

Weiter ist aus der DE-A-36 27 584 und aus Herstellerprospekten ein Fugenprofil für die vertikalen Fugen von Fassadenkonstruktionen bekannt, welches die Relativbewegung der Fassadenplatten in horizontaler Richtung in der Fassadenebene und das Klappern der Fassadenplatten bei Wind verhindern soll. Das Fugenprofil besteht aus einer Mittelsicke in der Breite der zwischen der Fassadenplatten angeordneten Vertikalfuge und zwei federnden Doppelschenkeln, die beiderseits der Mittelsicke angeordnet sind. Das Fugenprofil wird in langen Stangen montiert und sichert somit ein sauberes Fluchten der vertikalen Fugen. Der Nachteil dieser Konstruktion liegt darin, daß das beschriebene Fugenprofil wegen der erforderlichen Federwirkung aus sehr dünnem Material ausgeführt sein muß und deshalb bei der Montage leicht wegknickt bzw. bei der erforderlichen Sorgfalt einen hohen Montagezeitaufwand verursacht. Außerdem ist es aufgrund der erforderlichen 7-fachen Abkantung teuer in der Herstellung. Aus beiden Gründen erhöhen sich die Herstellkosten der fix und fertig montierten Fassadenkonstruktion. Ein weiterer Nachteil dieses Fugenprofils liegt darin, daß es die Vertikalfuge nur mangelhaft gegen Schlagregen abdichtet, da sich die Schenkel der Mittelsicke in gerader Linie bis zum Abstützpunkt am Tragprofil fortsetzen und deshalb durch herstellungsbedingte Toleranzen schmale Spalte verbleiben können, durch welche Wasser eingetrieben werden kann, welches bis zum Tragprofil und über dieses bis zur Wärmedämmung gelangt und diese durchfeuchtet.Next is from DE-A-36 27 584 and from manufacturer's brochures Joint profile known for the vertical joints of facade structures, which shows the relative movement of the facade panels in the horizontal direction the facade level and the clatter of the facade panels in the wind should prevent. The joint profile consists of a central bead in the width of the vertical joint arranged between the facade panels and two resilient Double legs, which are arranged on both sides of the center bead. The Joint profile is mounted in long rods and thus ensures a clean one Alignment of the vertical joints. The disadvantage of this construction is that the joint profile described because of the required spring action must be made of very thin material and therefore easy to assemble folds away or a high level with the necessary care Assembly time expenditure caused. It is also required due to 7-fold folding is expensive to manufacture. Increase for both reasons the manufacturing costs of the fully assembled facade construction. On Another disadvantage of this joint profile is that it is only the vertical joint insufficiently seals against driving rain, because the legs of the center bead Continue in a straight line to the support point on the support profile and therefore narrow gaps can remain due to manufacturing tolerances, through which water can be driven, which up to the support profile and through this to the insulation and moistened it.

Aus der DE-A-39 34 686 ist eine Befestigungsvorrichtung für Fassadenplatten bekannt, bei der die Halteprofile vertikal verlaufende Kastenprofile sind. Die Kastenprofile einer Fassadenplatte weisen jeweils einen Abstand voneinander auf, der geringer als die Breite der Fassadenplatten ist und deren Abstand zu dem Halteprofil der benachbarten Fassadenplatte durch ein Fugenprofil ausgefüllt ist, das in seinem mittleren Abschnitt mit vorspringenden seitlichen Anschlägen für die Fassadenplatten in die vertikale Fuge ragt.DE-A-39 34 686 is a fastening device for facade panels known in which the holding profiles are vertically extending box profiles. The Box profiles of a facade panel are spaced from each other on, which is smaller than the width of the facade panels and their distance to the holding profile of the neighboring facade panel with a joint profile is filled in that in its central section with projecting lateral Stops for the facade panels protrude into the vertical joint.

Aufgabe der Erfindung ist es deshalb, eine Fassadenkonstruktion zu beschreiben, bei welcher der Materialaufwand in Verbindung mit den Plattenhaltern verringert und die erforderliche Montagezeit verkürzt und die Schlagregensicherheit erhöht wird.The object of the invention is therefore to a facade construction describe in which the cost of materials in connection with the Reduced plate holders and shortened the required assembly time and the Driving rain safety is increased.

Die Lösung der gestellten Aufgabe erfolgt erfindungsgemäß durch das Kennzeichen des Anspruchs 1. Der Vorteil dieser Ausführungsform liegt darin, daß durch einen einzigen Plattenhalter jeweils zwei obere und zwei untere Fassadenplatten in ihren Eckbereichen an den Tragprofilen der Unterkonstruktion befestigt werden. In jedem Fugenkreuz der Fassade ist also ein Plattenhalter angeordnet; der Bedarf beträgt also in der Fläche der Fassade nur einen Plattenhalter pro Fassadenplatte, während bei den Fassadenkonstruktionen nach dem Stand der Technik zwei Plattenhalter pro Fassadenplatte erforderlich sind. Dadurch werden Materialkosten eingespart und die Montagezeiten verkürzt. Ein weiterer Vorteil dieser Ausführungsform liegt darin, daß die Fassadenplatten durch Zungen oder Laschen, welche an den Plattenhaltern genau übereinander fluchtend angebracht oder ausgeklinkt sind auf einem exakten Fugenabstand gehalten werden und daß dadurch die Vertikalfugen der jeweils oben angeordneten Plattenpaare mit den Vertikalfugen der jeweils unten angeordneten Plattenpaare genau fluchten. Dabei entspricht die Breite der Zungen oder Laschen mit dem erforderlichen relativ geringen Spiel der lichten Breite der vertikalen Fugen zwischen den Fassadenplatten. Anstelle der Zungen oder Laschen können auch doppelte Zungen oder Laschen ausgeklinkt sein, deren Gesamtmaß von Außenkante zu Außenkante der Breite einer einzelnen Zunge entspricht. Bei der Montage der Fassadenkonstruktion wird dabei jeweils die untere Zunge oder das untere Zungenpaar des Plattenhalters von oben in die Vertikalfuge des unteren Plattenpaares eingeführt, wodurch der Plattenhalter vor seiner endgültigen Befestigung am Tragprofil genau auf die Fugenmitte zentriert wird. Da auch die obere Zunge des Plattenhalters mittig über der unteren Zunge angeordnet ist, ergibt sich bei der Montage des oberen Plattenpaares zwangsläufig ein Fluchten der Vertikalfuge des oberen Plattenpaares mit der des unteren.According to the invention, the object is achieved by Characteristic of claim 1. The advantage of this embodiment is that that by a single plate holder two upper and two lower Facade panels in their corner areas on the support profiles of Substructure to be attached. So there is in each crosshairs of the facade a plate holder arranged; so the need is in the area of Facade only one Panel holder per facade panel, while the facade construction according to the state of the Technique two plate holders per facade plate are required. This will Material costs saved and assembly times shortened. Another advantage of this Embodiment is that the facade panels by tongues or tabs, which on the plate holders are flush aligned or notched on one exact joint spacing and that the vertical joints of the top arranged plate pairs with the vertical joints of the plate pairs arranged below exactly cursed. The width of the tongues or tabs corresponds to that required relatively little play of the clear width of the vertical joints between the facade panels. Instead of the tongues or tabs, double tongues or tabs can also be released be, the total dimension of the outer edge to outer edge of the width of a single tongue equivalent. When installing the facade construction, the lower tongue is used or the lower pair of tongues of the plate holder from above into the vertical joint of the lower one Plate pair introduced, whereby the plate holder before its final attachment to Support profile is centered exactly on the center of the joint. Since also the upper tongue of the record holder is arranged centrally over the lower tongue, results from the assembly of the upper Plate pair inevitably an alignment of the vertical joint of the upper plate pair with that of the lower.

Bei einer anderen besonders vorteilhaften Ausführungsform nach Anspruch 3 und 4 ist zwischen den Vertikalfugen des oberen und des unteren Plattenpaares ein Fugenprofil mit einer Sicke angeordnet, welches die vertikalen hinteren Kanten der beidseitig angeordneten Fassadenplatten umgreift und welches sich mittels beidseitiger einfacher federnder Schenkel am Plattenhalter bzw. an dem Tragprofil abstützt. Die an dem Plattenhalter angebrachten Zungen greifen dabei nicht direkt in die Vertikalfugen zwischen den jeweiligen Plattenpaaren ein sondern nur in die von hinten offenen Sicken der in den Vertikalfugen angeordneten Fugenprofile. Die Vorteile dieser Ausführungsform liegen darin, daß das Fugenprofil, welches vorzugsweise aus sehr dünnem Blech oder aus Kunststoff gefertigt ist, die Fassadenplatten zwar auf genauem Abstand hält, trotzdem aber im elastischen und plastischen Bereich so weit verformbar ist, daß es weder bei der Montage noch bei nachträglichen Relativbewegungen der Fassade durch Windlasten oder Gebäudesetzungen zu Zwangskräften und dadurch zur Beschädigung oder zum Bruch von Fassadenplatten kommen kann. Außerdem stützt sich das Fugenprofil mit den Enden seiner beiden nach außen gespreizten Schenkel in seinem unteren Bereich federnd an dem Plattenhalter und in seinem oberen Bereich federnd am Tragprofil ab und drückt dadurch die beidseitigen Fassadenplatten, deren vertikale rückseitige Kanten es umgreift, soweit elastisch zur Vorderseite der Fassade, bis das Spiel zwischen dem Kopf- bzw. dem Fußfalz der Fassadenplatten einerseits und dem Plattenhalter andrerseits ausgeglichen ist. Der Vorteil dieser Ausführungsform liegt einerseits darin, daß das Fugenprofil mit seinen einspringenden Kanten die hinteren vertikalen Kanten der Fassadenplatten eng umgreift und dadurch eine besonders wirksame Abdichtung gegen das Eindringen von Schlagregen bildet. Außerdem ist dieses Fugenprofil gegenüber dem Fugenprofil nach dem Stand der Technik wesentlich billiger, da es statt mit einer Sicke und 6 Abkantungen nur mit einer Sicke und 2 Abkantungen versehen ist. Ein weiterer Vorteil liegt darin begründet, daß es gleichzeitig mit den Fassadenplatten in kurzen Stücken montiert werden kann und die umständliche Handhabung der langen Fugenprofile nach dem Stand der Technik entfällt, wodurch Montagezeit eingespart wird.In another particularly advantageous embodiment according to claims 3 and 4 a joint profile with a between the vertical joints of the upper and the lower pair of plates Bead arranged, which arranged the vertical rear edges of the two sides Grips facade panels and which is by means of simple resilient legs on both sides Plate holder or supported on the support profile. The tongues attached to the plate holder do not intervene directly in the vertical joints between the respective plate pairs but only in the beads that are open from behind and arranged in the vertical joints Joint profiles. The advantages of this embodiment are that the joint profile, which is preferably made of very thin sheet metal or plastic, the facade panels holds at a precise distance, but still so far in the elastic and plastic range is deformable that it is neither in the assembly nor in subsequent relative movements of the Facade due to wind loads or building settlements to force and thereby to Damage or breakage of facade panels can occur. This is also supported Joint profile with the ends of its two outward spread legs in its lower Resilient area on the plate holder and in its upper area resilient on the support profile and thereby presses the double-sided facade panels, the vertical rear edges of which grips as far as elastic to the front of the facade until the play between the head or the rebate of the facade panels on the one hand and the panel holder on the other hand is balanced. The advantage of this embodiment is on the one hand that the joint profile with its protruding edges tightly embraces the rear vertical edges of the facade panels and thereby forming a particularly effective seal against the ingress of driving rain. In addition, this joint profile compared to the joint profile according to the prior art Much cheaper, since instead of one bead and 6 folds, there is only one bead and 2 Bends is provided. Another advantage lies in the fact that it works with the facade panels can be assembled in short pieces and the cumbersome Handling of the long joint profiles according to the prior art is eliminated, which means Assembly time is saved.

Eine andere vorteilhafte Ausführungsform der erfindungsgemäßen Fassadenkonstruktion nach Anspruch 5 besteht darin, daß die den Kopffalz der unteren beiden Fassadenplatten und/oder die den Fußfalz der oberen beiden Fassadenplatten umgreifenden U-förmigen Teil des Plattenhalters im Mittelteil derselben ausgeklinkt sind. Der daraus resultierende Vorteil besteht darin, daß die Kopf- bzw. Fußfalze der Fassadenplatten nicht am äußersten Ende auf Biegung belastet werden, da dort die Bruchgefahr am höchsten ist. Durch die Ausklinkung des Plattenhalters verlagert sich der jeweilige Lastenangriffspunkt der Plattenhalter vom Falzende weg in Richtung zur Falzmitte, wo die sogen. mittragende Breite des Falzes wesentlich größer ist. Versuche haben ergeben, daß bei Stoßbelastung der Fassadenplatten von der Fassadenvorderseite her die Falzbruchfestigkeit durch die beschriebene Verlagerung des Lastangriffspunktes bis auf das zweieinhalbfache zunimmt.Another advantageous embodiment of the facade construction according to the invention Claim 5 is that the top fold of the lower two facade panels and / or the U-shaped part of the footprint of the upper two facade panels Plate holder are released in the middle part of the same. The resulting benefit is there in that the head or foot folds of the facade panels do not bend at the extreme end be loaded because the risk of breakage is highest there. By notching the The respective load application point of the plate holder moves from the fold end to the plate holder away towards the center of the fold, where the so-called load-bearing width of the fold much larger is. Tests have shown that when the facade panels are subjected to shock loads from the Front of the facade the resistance to rebate by the described displacement of the Load application point increases up to two and a half times.

In weiterer Ausgestaltung der erfindungsgemäßen Fassadenkonstruktion nach Anspruch 6 sind die hinteren, den Kopffalz bzw. Fußfalz umgreifenden Schenkel des Plattenhalters an ihren Enden mit Verstärkungen versehen, welche zur Rückseite der Fassadenplatte hin ausgerichtet sind. Der Vorteil, der sich daraus ergibt, ist darin begründet, daß bei Einwirkung einer Stoßlast auf die Vorderseite der Fassadenplatte, der Lastangriffspunkt vom Kopf des jeweiligen Falzes zu seinem Fuß oder sogar bis zum eigentlichen Plattenkörper selbst verlagert wird. Das Ergebnis ist, daß die von der Fassadenplatte schadensfrei aufnehmbare Stoßlast gegenüber der Stoßlast, die von einer, mit einem konventionellen Halter befestigten Fassadenplatte aufgenommen werden kann, auf das Mehrfache ansteigt. Bei der Befestigung einer gleichartigen Fassadenplatte mit Plattenhaltern nach dem Stand der Technik macht die Fassadenplatte bei einer Stoßbelastung von vorne im Bereich des Spiels zwischen Plattenhalter und Kopffalz eine leichte Kippbewegung nach hinten und stützt sich dadurch mit der oberen Hinterkante des Kopffalzes am Plattenhalter ab. Das auf den Kopffalzfuß einwirkende Biegemoment hat deshalb wegen des langen Hebelarmes seine maximal mögliche Größe. Dagegen ist der Hebelarm des hinteren Schenkels des Plattenhalters an dieser Stelle sehr kurz, wodurch die elastische Verformbarkeit sehr gering ist. Beim erfindungsgemäßen Plattenhalter wird durch die Verlagerung des Lastangriffspunktes an das untere Ende des Schenkels des Plattenhalters nicht nur die Länge des wirksamen Hebelarmes des Kopffalzes erheblich verkürzt bzw. entfällt ganz; vielmehr wird gleichzeitig der wirksame Hebelarm des hinteren Schenkels des Plattenhalters erheblich verlängert, wodurch es in der Lage ist, die auf die Fassadenplatte aufgebrachten Stoßlasten wesentlich elastischer auf den Plattenhalter und damit auf die Unterkonstruktion abzutragen, als dies bei dem Plattenhaler nach dem Stand der Technik möglich istIn a further embodiment of the facade construction according to claim 6 are the rear, around the top fold or foot fold of the plate holder on their Provide ends with reinforcements, which are oriented towards the back of the facade panel are. The advantage that results from this is that, when exposed to a Impact load on the front of the facade panel, the load application point from the head of the relocated the respective fold to its foot or even to the actual panel body itself becomes. The result is that the impact load can be absorbed by the facade panel without damage against the impact load, which is fixed by a conventional holder Facade slab can be recorded, increases to multiple. When fixing a similar facade panel with panel holders according to the prior art makes the Facade panel with a shock load from the front in the area of play between the panel holder and top fold a slight tilting movement backwards and thereby supports itself with the upper one From the rear edge of the top fold on the plate holder. The one acting on the top rebate Bending moment therefore has its maximum possible size due to the long lever arm. In contrast, the lever arm of the rear leg of the plate holder is very short at this point, whereby the elastic deformability is very low. In the plate holder according to the invention is by moving the load application point to the lower end of the leg of the Plate holder not only the length of the effective lever arm of the top fold considerably shortened or omitted entirely; rather, at the same time, the effective lever arm of the rear Leg of the plate holder is significantly extended, which makes it able to move on the Facade panel applied impact loads much more elastic on the panel holder and thus to remove on the substructure, as this with the plate holder according to the state of the Technology is possible

Bei einer weiteren Ausführungsvariante der Fassadenkonstruktion wird auf die rückseitigen Schenkel des H-förmigen Teils des Plattenhalters verzichtet. Die Fassadenplatten werden dann lediglich durch die federnden Fugenprofile nach vorne gedrückt und stützen sich im Falle einer Stoßlast von vorne an der Vorderseite der Plattenhalter bzw. an der unteren Vorderkante der Tragprofile ab.In a further embodiment variant of the facade construction is on the back Leg of the H-shaped part of the plate holder waived.
