Description

Die Erfindung betrifft ein Paneel zur Bekleidung von Wän­den oder Decken von Bauwerken, wobei die beiden parallelen Längsränder des Paneels derart profiliert sind, daß sie formschlüssig ineinander passen und der Aufnahme-Längsrand in seinem Inneren eine Hinterschneidung und der Einsteck-­Längsrand bzw. der in den Aufnahme-Längsrand passende Längs­rand des Nachbarpaneels einen diese Hinterschneidung er­fassenden Vorsprung hat, wobei ein Hohlraum zwischen den Längsrändern und der Oberfläche des Paneels vorzugsweise mit einem Isolierstoff ausgeschäumt ist.The invention relates to a panel for cladding walls or ceilings of buildings, the two parallel longitudinal edges of the panel being profiled in such a way that they fit into one another in a form-fitting manner and the receiving longitudinal edge has an undercut in its interior and the longitudinal insertion edge or in the Longitudinal receptacle edge matching the longitudinal edge of the neighboring panel has a projection which detects this undercut, a cavity between the longitudinal edges and the surface of the panel preferably being foamed with an insulating material.

Ein derartiges Paneel ist aus DE-GM 71 02 476 bekannt. Da­bei ist allerdings nur ein kleinerer Teil des Aufnahme-­Längsrandes nutenförmig zur Aufnahme eines entsprechenden Vorsprunges des Einsteck-Längsrandes ausgebildet. Die Oberseiten benachbarter Paneelen sollen unmittelbar mit­einander fluchten. Deshalb sind bei diesem vorbekannten Paneel im Querschnitt drei Punkte gegeneinander verspannt, deren einer unmittelbar unterhalb der Oberfläche an sich stumpf berührenden Teilen der Längsränder liegt, während ein zweiter Berührungspunkt nahe dem Eintritt in den nu­tenförmigen Innenraum des Aufnahmelängsrandes angeordnet ist und der dritte, für die Verankerung wichtigste Punkt hinter der Hinterschneidung liegt. Durch diese Verspan­nung an drei Querschnittspunkten ist eine Aufnahme von Wärmedehnungen der Paneele praktisch ausgeschlossen oder nur über deren Verformung möglich. Somit besteht vor allem bei großen Temperaturschwankungen die Gefahr, daß sich der Paneelenverbund verwirft oder daß sogar die Verbin­dung benachbarter Paneelen gelöst wird.Such a panel is known from DE-GM 71 02 476. However, only a small part of the longitudinal edge of the receptacle is groove-shaped for receiving a corresponding projection of the longitudinal insertion edge. The tops of adjacent panels should be flush with one another. Therefore, in this known panel, three points are braced against one another in cross-section, one of which is located directly below the surface of the longitudinal edges of butt-touching parts, while a second point of contact is arranged near the entrance to the groove-shaped interior of the longitudinal edge of the receptacle, and the third, for anchoring most important point lies behind the undercut. Due to this bracing at three cross-sectional points, absorption of thermal expansion of the panels is practically impossible or is only possible via their deformation. Thus, especially in the case of large temperature fluctuations, there is a risk that the panel assembly warps or that even the connection of adjacent panels is released.

Es besteht deshalb die Aufgabe, ein Paneel der eingangs erwähnten Art zu schaffen, mit welchem bei definierter Einstecktiefe der Längsränder benachbarter Paneele inein­ander auch größere Wärmedehnungen ohne Verformung der Paneele und ohne Lösung der Verbindung aufgefangen werden können.There is therefore the task of creating a panel of the type mentioned at the outset, with which, with a defined insertion depth of the longitudinal edges of adjacent panels, larger thermal expansions can be absorbed without deformation of the panels and without loosening the connection.

Die Lösung dieser Aufgabe besteht im wesentlichen darin, daß der die Hinterschneidung aufweisende Aufnahme-Längs­rand in Einsteckrichtung vor der Hinterschneidung zwei einander gegenüberliegende, etwa parallel zur Paneelober­fläche verlaufende Wandungen hat und in Gebrauchsstellung damit die Ober- und Unterseite des Längsrandes des Nach­barpaneels umgreift, daß der umgriffene Einsteck-Längs­rand des Nachbarpaneels gegenüber seiner Oberseite zu­rückspringt und daß in Gebrauchsstellung zwischen der Stirnseite des Einsteck-Längsrandes und dem Nutengrund des Aufnahme-Längsrandes sowie zwischen der in Einsteck­richtung vorderen Seite der Hinterschneidung und dem die­ser gegenüber zurückspringenden Bereich des Einsteck-­Längsrandes jeweils ein Spiel vorgesehen ist. Dieses Spiel an allen in Fortsetzung der Paneele rechtwinklig zu ihren Verbindungsrändern verlaufenden Abmessung er­laubt es, daß die beiden Längsränder sich in dieser Rich­tung beidseits verschieben und auch ineinander verschie­ben können, wenn sich die Paneele aufgrund größerer Er­wärmungen ausdehnen. Gleichzeitig ist aber dennoch ein ungewolltes Herausziehen eines Paneels aus dem anderen während der Montage oder ein ungenügend tiefes Einstek­ken dadurch verhindert, daß durch die Hinterschneidung und den dazu passenden Vorsprung Formschluß entgegen der Lösebewegung existiert. Der Monteur kann praktisch nach dem Zusammenfügen zweier Paneelen diese in fluchtender Position etwas auseinanderziehen, so daß der Vorsprung an der Rückseite der Hinterschneidung anschlagen kann. Damit wird auch die größtmögliche Spielfreiheit in Ein­steckrichtung, d.h. für Wärmedehnungen eingestellt.The solution to this problem consists essentially in the fact that the longitudinal undercut receiving the undercut has two mutually opposite walls approximately parallel to the panel surface in the insertion direction before the undercut and in the use position thus encompasses the top and bottom of the longitudinal edge of the adjacent panel so that the encompassed insertion longitudinal edge of the neighboring panel springs back relative to its upper side and that in the position of use between the end face of the insertion longitudinal edge and the groove bottom of the receiving longitudinal edge as well as between the front side of the undercut in the insertion direction and the area of the insertion longitudinal edge which recesses opposite this, a game in each case is provided. This play on all dimensions extending from the panels at right angles to their connecting edges allows the two longitudinal edges to shift in this direction on both sides and also to move into one another if the panels expand due to greater heating. At the same time, however, is a inadvertent pulling out of one panel from the other during assembly or an insufficiently deep insertion prevents the undercut and the matching projection from engaging in a form-locking manner against the release movement. After assembling two panels, the fitter can practically pull them apart somewhat in the aligned position so that the projection can strike the rear of the undercut. This also sets the greatest possible freedom of play in the direction of insertion, ie for thermal expansion.

Besonders zweckmäßig und für die Montage günstig ist es, wenn der Abstand der Außenseiten der den Aufnahme-Längs­rand bildenden Wandungen etwa der Gesamtdicke oder -stärke des Paneels entspricht. Entsprechend groß ist die Einstecköffnung dieses Längsrandes und entsprechend ein­fach die Montage.It is particularly expedient and favorable for assembly if the distance between the outer sides of the walls forming the longitudinal edge of the receptacle corresponds approximately to the total thickness or thickness of the panel. The insertion opening of this longitudinal edge is correspondingly large and the assembly is correspondingly simple.

Die Hinterschneidung kann als im Querschnitt etwa säge­zahnartiger Vorsprung mit in Einsteckrichtung schrägem Anstieg und an der Rückseite etwa rechtwinklig zur Nuten­wand verlaufende Anschlagfläche ausgebildet sein. Prak­tisch bildet nämlich der Einsteck-Längsrand eine Nut, deren eine Wandung die vorspringende Hinterschneidung auf­weist. Der dazu passende Vorsprung kann leicht hinter diese Hinterschneidung gebracht werden, indem das Paneel mit dem Einsteck-Längsrand zunächst etwas schräg zu dem Paneel mit dem Aufnahme-Rand gehalten wird, bis der Vor­sprung in den Bereich hinter der Hinterschneidung ge­langt ist. Durch Zurückkippen des schrägen Paneels in fluchtende Position zu dem anderen Paneel gelangt dann der Vorsprung direkt hinter die Hinterschneidung.The undercut can be designed as a sawtooth-like projection in cross section with an inclined rise in the insertion direction and on the rear side of the stop surface running approximately at right angles to the groove wall. Practically, the longitudinal insertion edge forms a groove, one wall of which has the projecting undercut. The matching projection can easily be placed behind this undercut by initially holding the panel with the longitudinal insertion edge at a slight angle to the panel with the receiving edge until the projection has reached the area behind the undercut. By tilting the inclined panel back into alignment with the other panel, the projection then comes directly behind the undercut.

Vorteilhaft und für Herstellung einfach sowie für eine feste Verbindung entgegen der Einsteckrichtung zweckmäßig ist es, wenn der in Gebrauchsstellung die Hin­terschneidung innerhalb des Aufnahme-Längsrandes hinter­greifende Vorsprung im Querschnitt etwa hakenförmig aus­gebildet ist und das Hakenende in Gebrauchsstellung an der rückseitigen Anschlagfläche der Hinterschneidung an­liegt, während die Außenseite des Hakens zu dem Nuten­grund des Aufnahme-Längsrandes das schon erwähnte Spiel aufweist.Advantageous and easy to manufacture and for a firm connection against the direction of insertion It is expedient if the projection engaging behind the undercut within the longitudinal receiving edge is approximately hook-shaped in cross-section and the hook end in the use position rests against the rear stop face of the undercut, while the outside of the hook already does so to the groove base of the longitudinal receiving edge has mentioned game.

Um die Montage zu erleichtern und dabei eventuelle Auf­biegungen der beiden Wandungen des Aufnahme-Längsrandes zu vermeiden, ist es zweckmäßig, wenn ein den Hakenrücken bildender Bereich des Einsteck-Längsrandes im Querschnitt schräg zur Stirnseite des Hakens hin in dem Sinne ver­läuft, daß sich der den Haken-Querschnitt aufweisende Längsrand zu seiner Stirnseite hin verjüngt. Diese Ver­jüngung in Verbindung mit der Hakenöffnung erlaubt es, durch etwas schräge Anordnung des Paneels mit dem Ein­steckrand den schmaleren Zwischenraum zwischen der Hin­terschneidung und der gegenüberliegenden Wandung des Aufnahme-Längsrandes mit dem Hakenteil zu überwinden, ohne daß dabei die beiden Wandungen auseinandergezwängt werden müßten. Ebenso kann auf diese Weise auch eine Demontage ohne Beschädigung der Längsränder erfolgen.In order to facilitate assembly and to avoid possible bending of the two walls of the longitudinal edge of the receptacle, it is expedient if an area of the longitudinal insertion edge forming the hook back runs obliquely in cross section towards the end face of the hook in the sense that the Longitudinal edge with hook cross-section tapers towards its end face. This taper in connection with the hook opening makes it possible to overcome the narrower space between the undercut and the opposite wall of the longitudinal receiving edge with the hook part by means of a somewhat oblique arrangement of the panel with the insertion edge, without the two walls having to be forced apart. It can also be disassembled without damaging the longitudinal edges.

Ausgestaltungen der Erfindung und insbesondere der Form der Längsränder sind Gegenstand der Ansprüche 6 bis 13. Dabei ist besonders vorteilhaft die Maßnahme des Anspru­ches 9, wonach nämlich die Dickenverminderung des Paneels an dem Einsteck-Längsrand breiter als ihr Eingriff in den Gegen-Längsrand ist, so daß in montiertem Zustand eine Kontrollfuge mit zwei parallelen Bereichen der ineinander­greifenden Längsrändern gebildet ist. Somit ist auf einen Blick eine Kontrolle möglich, ob die beiden Ränder rich­tig ineinandergesteckt sind und auf einfache Weise kann nachgemessen werden, ob dabei auch das Hakenstück an der Innenseite der Hinterschneidung anliegt und somit das ge­wünschte Spiel an den eigentlichen Stirnseiten vorhanden ist. Da die Verminderung der Dicke in diesem Randbereich relativ geringfügig ist, weil sie lediglich der Stärke der einen Wandung des Aufnahme-Längsrandes entspricht., ergibt sich praktisch keine Beeinträchtigung der Isolier­wirkung.Embodiments of the invention and in particular the shape of the longitudinal edges are the subject of claims 6 to 13. The measure of claim 9 is particularly advantageous, according to which the thickness reduction of the panel on the insertion longitudinal edge is wider than its engagement in the opposite longitudinal edge that a control joint is formed with two parallel areas of the interlocking longitudinal edges in the assembled state. This makes it possible to check at a glance whether the two edges are correctly inserted and can be easily be checked whether the hook piece also bears against the inside of the undercut and whether the desired play is present on the actual end faces. Since the reduction in thickness in this edge region is relatively slight, because it only corresponds to the thickness of one wall of the longitudinal edge of the receptacle, there is practically no impairment of the insulating effect.

Die Wahl der Abmessungen der Dicke der Längsränder, die die beiden Längsränder in Gebrauchsstellung einen Klemm-­oder Preßsitz miteinander haben läßt, ergibt eine gute Abdichtung an den Berührungsstellen der Längsränder.The choice of the dimensions of the thickness of the longitudinal edges, which allows the two longitudinal edges to have a clamp or press fit with one another in the position of use, results in a good seal at the contact points of the longitudinal edges.

Vor allem bei Kombination der vorbeschriebenen und in den Ansprüchen erwähnten Maßnahmen und Merkmalen ergibt sich ein Paneel, welches eine einfache Verbindung mit dem Nach­barpaneel erlaubt, dennoch auch große Wärmedehnungen zu­läßt ohne daß Elastizitätskräfte an den Paneelen wirksam werden und dabei den Herstellungsaufwand praktisch nicht verändert. Obwohl die Längsränder eine Relativverschie­bung der Paneele erlauben, sind sie praktisch formschlüs­sig verbunden, so daß eine definierte und festgelegte Einstecktiefe bei der Montage sichergestellt werden kann. Da der Aufnahme-Längsrand praktisch die gesamte Dicke der Paneele ausnutzen kann, ist die erfindungsgemäße Ausbil­dung der Paneele vor allem auch dann gut anwendbar, wenn die Paneele eine relativ geringe Gesamtdicke von bei­spielsweise zwischen 10 und 20 mm haben. Dies ist auch des­halb vorteilhaft, weil gerade dünnere Paneele unter Wärme­spannungen noch schneller zu Verwerfungen neigen würden, die bei der erfindungsgemäßen Ausgestaltung durch die vorgesehenen Verschiebespielräume aber vermieden werden.Especially when combining the measures and features described above and in the claims results in a panel that allows a simple connection to the neighboring panel, but also allows large thermal expansions without elastic forces acting on the panels and practically not changing the manufacturing effort. Although the longitudinal edges allow a relative displacement of the panels, they are practically positively connected, so that a defined and defined insertion depth can be ensured during assembly. Since the longitudinal edge of the receptacle can practically utilize the entire thickness of the panels, the design of the panels according to the invention is particularly well applicable even if the panels have a relatively small overall thickness of, for example, between 10 and 20 mm. This is also advantageous because, in particular, thinner panels would tend to warp even more quickly under thermal stresses, but which are avoided in the embodiment according to the invention by the provided freedom of movement.

  • Fig. 2 is a representation corresponding approximately to Fig.1, wherein a panel is inclined relative to the neighboring panel in order to be assembled or separated therefrom and to enable simple assembly or disassembly despite the positive engagement in the use position according to Fig.1.

Ein Paneel 1 dient zu Bekleidung von Wänden oder Decken von Bauwerken, wobei die beiden parallelen Längsränder 2 und 3 des Paneels 1 derart profiliert sind, daß sie gemäß Fig. 1 formschlüssig ineinanderpassen. Dabei hat der Aufnahme-Längsrand 2 in seinem Inneren eine Hinter­schneidung 4 und der Einsteck-Längsrand 3 bzw. der in den Aufnahme-Längsrand 2 passende Längsrand 3 des Nachbar­paneels einen diese Hinterschneidung 4 erfassenden Vor­sprung 5. Der Hohlraum zwischen den Längsrändern 2 und 3 und der Oberfläche 6 des Paneels 1 ist im Ausführungsbei­spiel mit einem Isolierwerkstoff 7 ausgeschäumt.A panel 1 is used to clad walls or ceilings of buildings, the two parallel longitudinal edges 2 and 3 of the panel 1 being profiled such that they fit into one another in a form-fitting manner according to FIG. 1. The receiving longitudinal edge 2 has an undercut 4 in its interior and the insertion longitudinal edge 3 or the longitudinal edge 3 of the neighboring panel that fits into the receiving longitudinal edge 2 has a projection 5 that detects this undercut 4. The cavity between the longitudinal edges 2 and 3 and the surface 6 of the panel 1 is foamed in the exemplary embodiment with an insulating material 7.

In beiden Figuren erkennt man, daß der die Hinterschnei­dung 4 aufweisende Aufnahme-Längsrand 2 in Einsteckrich­tung vor der Hinterschneidung 4 zwei einander gegenüber­liegende etwa parallel zur Paneeloberfläche 6 verlaufende Wandungen 8 und 9 hat und in Gebrauchsstellung gem. Fig.1 damit die Oberseite 10 und die Unterseite 11 des Ein­steck-Längsrandes 3 des Nachbarpaneels umgreift. Dabei springt der umgriffene Einsteck-Längsrand 3 gegenüber sei­ner Oberseite 6 zurück, so daß die Oberseite 10 dieses Längsrandes 3 gegen die Oberseite 6 des Paneels etwas zu­rückliegt. Vor allem wird in Fig. 1 deutlich, daß in Ge­brauchsstellung zwischen der Stirnseite 12 des Einsteck-­Längsrandes 3 und dem Nutengrund 13 des etwa nutenförmi­gen Aufnahme-Längsrandes 3 und ferner zwischen der in Ein­steckrichtung vorderen Seite oder Fläche 14 der Hinter­schneidung 4 und dem dieser gegenüber zurückspringenden Bereich 15 des Einsteck-Längsrandes 3 jeweils ein Spiel vorgesehen ist. Dabei entspricht der Abstand der Außen­seiten der den Aufnahme-Längsrand 2 bildenden Wandungen 8 und 9 im Ausführungsbeispiel der Gesamtdicke oder -stärke des Paneels 1, so daß insgesamt eine möglichst große Öff­nung an diesem Einsteck-Längsrand 2 vorhanden ist, wodurch diese Lösung auch für relativ dünne Paneele 1 zweckmäßig und vorteilhaft wird.In both figures it can be seen that the longitudinal undercut 4 having the undercut 4 in the insertion direction in front of the undercut 4 has two mutually opposite walls 8 and 9 which run approximately parallel to the panel surface 6 and according to the position of use. Fig.1 so that the top 10 and the bottom 11 of the insertion longitudinal edge 3 of the neighboring panel encompasses. Here the encompassed insertion longitudinal edge 3 jumps back relative to its upper side 6, so that the upper side 10 of this longitudinal edge 3 lies somewhat behind the upper side 6 of the panel. In particular, it is clear in Fig. 1 that in the position of use between the end face 12 of the insertion longitudinal edge 3 and the groove bottom 13 of the approximately groove-shaped receiving longitudinal edge 3 and also between the front side or surface 14 of the undercut 4 in the direction of insertion and this opposite recessed area 15 of the insertion longitudinal edge 3 a game is provided. The distance between the outer sides of the walls 8 and 9 forming the longitudinal longitudinal edge 2 in the exemplary embodiment corresponds to the total thickness or thickness of the panel 1, so that overall the largest possible opening is present on this longitudinal longitudinal edge 2, which also makes this solution relatively thin panels 1 is useful and advantageous.

Die Hinterschneidung 4 ist im Ausführungsbeispiel als im Querschnitt etwa sägezahnartiger Vorsprung mit in Ein­steckrichtung schrägem Anstieg an ihrer Vorderseite 14 und an der Rückseite etwa rechtwinklig zur Nutenwand 8 verlaufender Anschlagfläche 16 ausgebildet. Gegebenenfalls genügt dabei auch ein etwas stumpferer als ein rechter Winkel oder es könnte sogar ein spitzer Winkel dieser An­schlagfläche 16 zur Nutenwand 8 vorgesehen werden.The undercut 4 is formed in the exemplary embodiment as a sawtooth-like projection in cross section with an inclined rise in the insertion direction on its front side 14 and on the rear side approximately at right angles to the groove wall 8 stop surface 16. If necessary, a somewhat more obtuse angle than a right angle is sufficient, or an acute angle of this stop surface 16 to the groove wall 8 could even be provided.

Der in Gebrauchsstellung die Hinterschneidung 4 innerhalb des Aufnahme-Längsrandes 2 hintergreifende Vorsprung 5 ist etwa hakenförmig ausgebildet. Gemäß Fig. 1 liegt zweckmäßigerweise das Hakenende 17 in Gebrauchsstellung an der rückseitigen Anschlagfläche 16 der Hinterschnei­dung 4 an, während die Außenseite des Hakens als Stirn­seite 12 zu dem Nutengrund 13 des Aufnahme-Längsrandes 2 das schon erwähnte Spiel aufweist. Somit ergibt sich bei der Montage eine definierte Lage der beiden Paneele zuein­ander, wobei gleichzeitig im Inneren der an sich form­schlüssigen Verbindung genügend Bewegungsspielraum für Wärmedehnungen eingeplant ist. Es können also Wärmedeh­nungen ungehindert stattfinden, ohne daß dabei die Elasti­zitätskräfte der Paneele beansprucht würden, falls das Spiel entsprechend dem Ausdehnungskoeffizienten ausrei­chend groß gewählt ist. Somit werden auch Verwerfungen der Paneele bei starker Erwärmung aufgrund ihres gegen­seitigen Verbundes von vorneherein vermieden.The projection 5 engaging behind the undercut 4 within the longitudinal receiving edge 2 in the use position is approximately hook-shaped. According to FIG. 1, the hook end 17 in the position of use expediently bears against the rear abutment surface 16 of the undercut 4, while the outside of the hook as the end face 12 to the groove bottom 13 of the longitudinal receiving edge 2 has the aforementioned play. This results in a defined position of the two panels relative to one another, at the same time sufficient freedom of movement for thermal expansion is planned in the interior of the interlocking connection. Thermal expansion can therefore take place without hindrance without the elastic forces of the panels being stressed if the play is chosen to be sufficiently large in accordance with the coefficient of expansion. This also prevents warping of the panels from the outset in the event of excessive heating due to their mutual connection.

Ein den Hakenrücken bildender Bereich 18 des Einsteck-­Längsrandes 3 verläuft im Querschntt schräg zur Stirn­seite 12 des Hakens bzw. des Paneels 1 hin in dem Sinne, daß sich der Querschnitt des Einsteck-Längsrandes 3 zu seiner Stirnseite 12 hin verjüngt. Vor allem in Fig. 2 erkennt man die Besonderheit und Bedeutung dieser Maß­nahme, die ein Einführen des Längsrandes 3 in den Längs­rand 2 trotz der im Inneren des Längsrandes 2 befindli­chen Hinterschneidung 4 erlaubt. Dabei spielt auch die Verringerung der Dicke des Längsrandes 3 im Bereich seiner Oberseite 10 und die Länge der Wandung 8 eine ent­sprechende Rolle und es ist dafür gesorgt, daß die Länge einer gedachten senkrechten Linie auf die den Hakenrük­ken bildende Schräge 18 des Einsteck-Längsrandes 3 bis zur gegenüberliegenden etwas eingezogenen Oberseite 10 dieses Längsrandes 3 gleich oder kleiner als der Abstand der beiden Innenseiten der Wandungen 8 und 9 der den Auf­nahme-Längsrand 2 bildende Nut ist. Gemäß Fig. 2 braucht also nur die einzuführende Paneele etwas schräg zu der Nachbarpaneele gestellt zu werden, um die beiden Längs­ränder 2 und 3 ohne Kraftanstrengung und ohne Verformun­gen ineinander führen zu können. Ist der Vorsprung 5 in dem Bereich hinter der Hinterschneidung 4 angelangt, wird die schrägstehende Paneele in Flucht mit der anderen Paneele 1 gebracht, wonach die Situation gemäß Fig. 1 hergestellt ist. Gegebenenfalls kann noch eine leichte Zugkraft auf die beiden Paneelen entgegen ihrer Einsteck­richtung aufgebracht werden, um die Hakenfläche 17 an der Anschlagfläche 16 des Vorsprunges 4 zur Anlage zu bringen.A region 18 of the insertion longitudinal edge 3 forming the hook back runs obliquely in the cross-section towards the end face 12 of the hook or panel 1 in the sense that the cross section of the insertion longitudinal edge 3 tapers towards its end face 12. Above all in FIG. 2, one can see the peculiarity and importance of this measure, which allows the longitudinal edge 3 to be inserted into the longitudinal edge 2 despite the undercut 4 located in the interior of the longitudinal edge 2. The reduction in the thickness of the longitudinal edge 3 in the region of its top 10 and the length of the wall 8 also play a corresponding role and it is ensured that the length of an imaginary vertical line on the bevel 18 forming the hook back of the insertion longitudinal edge 3 to to the opposite, somewhat retracted upper side 10 of this longitudinal edge 3 is equal to or smaller than the distance between the two inner sides of the walls 8 and 9 of the groove forming the receiving longitudinal edge 2. According to FIG. 2, only the panels to be inserted need to be set somewhat obliquely to the neighboring panels in order to be able to guide the two longitudinal edges 2 and 3 into one another without exertion of force and without deformations. When the projection 5 has reached the area behind the undercut 4, the sloping panels are in alignment with the other Panels 1 brought, after which the situation according to FIG. 1 is established. If necessary, a slight tensile force can still be applied to the two panels against their insertion direction in order to bring the hook surface 17 against the stop surface 16 of the projection 4.

Der in Gebrauchsstellung umgriffene Einsteck-Längsrand 3 verjüngt sich auch an dem der Oberseite 6 benachbarten zurückspringenden Bereich 10 unmittelbar vor der Hinter­schneidung 4 bis in die Hakenöffnung hinein ebenfalls, wobei die Schräge dieser Verjüngung in Gebrauchsstellung parallel zu der Schräge an der Vorderseite 14 der Hinter­schneidung 4 verläuft. Praktisch ergibt sich somit für den Einsteck-Rand 3 zu seiner Stirnseite 12 hin auf beiden Seiten eine Abschrägung, durch welche der Querschnitt dieses Längsrandes 3 zur Stirnseite 12 hin verjüngt wird. Auch dadurch wird die Einsteckmontage gemäß Fig. 2 er­leichtert.The inserted longitudinal edge 3 encompassed in the use position also tapers in the recessed area 10 adjacent to the upper side 6 immediately before the undercut 4 into the hook opening, the bevel of this taper in the use position parallel to the bevel on the front side 14 of the undercut 4 runs. In practice, this results in a bevel on both sides for the insertion edge 3 toward its end face 12, through which the cross section of this longitudinal edge 3 is tapered toward the end face 12. This also facilitates the plug-in assembly according to FIG. 2.

In Fig. 1 erkennt man noch, daß der Rand der oberseitigen Wandung 8 des Aufnahme-Längsrandes 2 in Gebrauchsstellung zumindest bis zum Anfang 19 der an der gegenüberliegenden Seite des Einsteck-Längsrandes 3 befindlichen Schräge 18 reicht oder diesen Anfang 19 sogar überragt. Dadurch er­gibt sich auch in Querrichtung eine feste Verbindung der beiden Paneele 1, so daß ihre Oberflächen 6 sicher mit­einander fluchten.In Fig. 1 it can still be seen that the edge of the top wall 8 of the receiving longitudinal edge 2 in the position of use extends at least to the beginning 19 of the bevel 18 located on the opposite side of the insertion longitudinal edge 3 or even exceeds this beginning 19. This also results in a firm connection of the two panels 1 in the transverse direction, so that their surfaces 6 are securely aligned with one another.

Die Verminderung 10 der Dicke des Paneels 1 an dem Ein­steck-Längsrand 3 ist im Ausführungsbeispiel breiter als ihr Eingriff in den Gegen-Längsrand 2 in Gebrauchs­stellung, so daß in montiertem Zustand eine Kontrollfuge 20 mit zwei parallelen Bereichen der ineinandergreifenden Längsränder gebildet ist, nämlich dem Rand der Wandung 8 einerseits und der Abkröpfung 21, die die Dickenvermin­ derung 10 bewirkt. Nach der Montage kann die Breite der Nut 20 überprüft werden und wenn ihre Begrenzungen nicht parallel laufen, ist die Zusammenfügung der Längsränder noch nicht in Ordnung. Ferner könnte eine zu schmale Kon­trollfuge 20 darauf hindeuten, daß das Spiel zwischen den Stirnseiten 12 und 13 im Inneren der Steckverbindung nicht vorhanden oder zu gering vorgewählt ist.The reduction 10 in the thickness of the panel 1 on the insertion longitudinal edge 3 is wider in the exemplary embodiment than its engagement in the opposite longitudinal edge 2 in the use position, so that in the assembled state a control joint 20 is formed with two parallel areas of the interlocking longitudinal edges, namely the Edge of the wall 8 on the one hand and the offset 21, which the Dickenvermin change 10 causes. After assembly, the width of the groove 20 can be checked and if its boundaries are not parallel, the joining of the longitudinal edges is not yet in order. Furthermore, a control joint 20 which is too narrow could indicate that the play between the end faces 12 and 13 is not present in the interior of the plug connection or is selected too little.

Die Hinterschneidung 4 ist dabei im Ausführungsbeispiel in dem nutenförmigen Aufnahme-Längsrand 2 an der Nuten­wandung 8 angeordnet, die an der Oberfläche 6 des Paneels 1 vorgesehen ist bzw. sich an diese anschließt, während die gegenüberliegende Nutenwand 9 als verlänger­ter Schenkel des das Paneel 1 im wesentlichen bildenden Werkstoffes, beispielsweise eines Aluminiumbleches, aus­gebildet ist. Somit lassen sich auch diese Ränder 2 und 3 gut einstückig mit dem Paneel 1 fertigen, biegen und formen.The undercut 4 is arranged in the embodiment in the groove-shaped receiving longitudinal edge 2 on the groove wall 8, which is provided on the surface 6 of the panel 1 or adjoins this, while the opposite groove wall 9 as an extended leg of the panel 1 in essential forming material, for example an aluminum sheet, is formed. These edges 2 and 3 can thus also be manufactured, bent and shaped in one piece with the panel 1.

Dabei kann dann auch dafür gesorgt werden, daß die beiden Längsränder 2 und 3 in Gebrauchsstellung einen Klemm- und Preßsitz miteinander haben, so daß in diesem Bereich eine gute Abdichtung erzielt und somit auch Regen von der be­kleideten Wandung abgehalten werden kann. Die diesem Regen ausgesetzte Oberseite 6 und die dort befindliche flache Fuge 20 können somit bei vertikaler Anordnung solches Wasser ableiten, ohne daß es in das Innere der Längsrän­der gelangt. Selbst geringfügige Flüssigkeitsmengen im Inneren der Steckverbindung können nach unten ablaufen, weil sie an der Berührung zwischem dem Anfang 19 der Schräge 18 und der Wandung 9 wiederum an einem weiteren Vordringen zu der Rückseite der Paneele 1 und somit zu der Gebäudewand hin gehindert wird.It can then also be ensured that the two longitudinal edges 2 and 3 have a clamping and press fit with one another in the position of use, so that a good seal is achieved in this area and rain can also be prevented from the clad wall. The top 6 exposed to this rain and the flat joint 20 located there can thus drain off such water in a vertical arrangement without it reaching the interior of the longitudinal edges. Even small amounts of liquid inside the plug connection can drain downwards because they are prevented from making further contact with the beginning 19 of the slope 18 and the wall 9 from penetrating further to the rear of the panels 1 and thus to the building wall.

Die vorzugsweise aus Aluminiumblech gebildete Haut 22 des Paneels 1 ist in einem Stück zu dem Hakenquerschnitt ge­bogen und hat am Ende des schrägen Hakenrückens 18 vor der Montage zweckmäßigerweise einen etwas größeren Ab­stand zu der gegenüberliegenden Außenseite 10 des Ein­steck-Längsrandes 3 als nach der Montage, so daß dieser umgebogene Randbereich bei der Montage federartig zusam­mendrückbar ist. Dadurch wird der erwähnte Klemmsitz und die Abdichtwirkung durch die Montage von selbst erreicht. Der schräge Hakenrücken 18 hat dabei an seinem Anfang 19 noch eine Fortsetzung 23 parallel zur Oberfläche 6, die von der Nutenwandung 9 des Aufnahme-Längsrandes 2 des Nachbarpaneeles in Gebrauchsstellung im Ausführungsbei­spiel gemäß Fig. 1 überragt ist. Somit wird die erwähnte geringfügige Federkraft an diesem Anfang 19 besser ver­teilt.The skin 22 preferably formed from aluminum sheet Panel 1 is bent in one piece to the cross-section of the hook and at the end of the oblique hook back 18 before assembly, it is expedient to have a slightly greater distance from the opposite outer side 10 of the longitudinal insertion edge 3 than after assembly, so that this bent-over edge region is spring-like during assembly is compressible. As a result, the aforementioned press fit and the sealing effect is achieved by the assembly by itself. The oblique hook back 18 has at its beginning 19 a continuation 23 parallel to the surface 6, which is surmounted by the groove wall 9 of the receiving longitudinal edge 2 of the neighboring panel in the use position in the exemplary embodiment according to FIG. 1. Thus, the aforementioned slight spring force is better distributed at this beginning 19.
