Description

Die Erfindung betrifft eine Vorrichtung zur Befestigung von hinterlüfteten Fassaden an Gebäudewänden, mit einem an der Außenwand befestigbaren Tragprofil, einem verstellbaren Distanzhalter und einem Fassadenhalter, der in variablem Abstand zur Außenwand an dem Distanzhalter oder dem Tragprofil befestigbar ist.The invention relates to a device for fastening ventilated facades to building walls, with a support profile attachable to the outer wall, an adjustable spacer and a facade holder which can be attached at a variable distance from the outer wall to the spacer or the support profile.

Hinterlüftete Fassaden sind ein bekanntes Mittel zur Gestaltung oberhalb des Erdbereichs befindlicher Außenwände. Eine gattungsgemäße Vorrichtung ist nach der DE-A-26 39 552 bekanntgeworden. Bei dieser besteht jedoch der Nachteil, daß vom Fassadenhalter ausgehende Belastungen nicht zentrisch auf die Wandbefestigungselemente übertragen werden, so daß Momente entstehen, die eine höhere Dimensionierung der Tragprofile einschließlich der Schraubbolzenverbindungen erfordern als es bei zentrischer Krafteinleitung nötig wäre. Darüber hinaus ist bei der bekannten Vorrichtung erforderlich, während der Montage Distanzhalter und Fassadenhalter sofort miteinander und mit dem Tragprofil fest zu verbinden, so daß eventuell erforderliches Nachrichten erschwert wird. Die Herstellungs- und Montagekosten sind daher bei dieser Vorrichtung relativ hoch. Ferner ist die bekannte Vorrichtung aufgrund der geometrischen Ausbildung von Wandhalter und Distanzhalter nicht zur Aufnahme von großgewichtigen Fassadenplatten geeignet, da dann das Rastermaß der Fassadenunterkonstruktion so stark verkleinert werden muß, daß aus Kostengründen von einer Anwendung vielfach abgesehen wird.Ventilated facades are a well-known means of designing external walls located above the earth. A generic device has become known from DE-A-26 39 552. In this case, however, there is the disadvantage that loads originating from the facade holder are not transferred centrally to the wall fastening elements, so that moments arise which require a higher dimensioning of the support profiles, including the screw connections, than would be necessary with a central introduction of force. In addition, in the known device it is necessary to immediately connect the spacer and the facade holder to one another and to the support profile so that any necessary messages are made more difficult. The manufacturing and assembly costs are therefore relatively high in this device. Furthermore, the known device is not suitable for accommodating large-weight facade panels due to the geometric design of the wall bracket and spacer, since the grid dimension of the facade substructure must then be reduced so much that an application is often omitted for cost reasons.

Die Aufgabe der Erfindung besteht darin, eine Vorrichtung zur Befestigung von hinterlüfteten Fassaden an Gebäudewänden zu schaffen, die auch bei schweren Fassadenplatten nur wenig Wandbefestigungselemente benötigt, aus wenig einfach und preiswert herzustellenden Bauelementen großer Eigensteifigkeit besteht sowie, ohne enge Toleranzen einhalten zu müssen, leicht und schnell ohne besondere Sicherheitsmaßnahmen in einem beliebigen Rastermaß zu montieren ist, wobei eine feste Verbindung von Distanzhalter und Fassadenhalter erst nach Ausrichten der Vorrichtung erforderlich ist.The object of the invention is to provide a device for fastening rear-ventilated facades to building walls, which requires only a few wall fastening elements even with heavy facade panels, consists of components which are easy and inexpensive to manufacture and which have great inherent rigidity and, without having to adhere to narrow tolerances, easily and can be quickly installed in any grid dimension without special safety measures, whereby a fixed connection of the spacer and facade holder is only required after the device has been aligned.

  • b) der Distanzhalter ist als Profilkörper mit H-förmigem Querschnitt ausgebildet, dessen einer gabelförmiger Abschnitt in gleichem Abstand wie die Seitenstege der Halteschiene angeordnete Seitenstege aufweist und dessen anderer gabelförmiger Abschnitt derart ausgebildet ist, daß dessen Seitenstege zwischen die Seitenstege der Halteschiene schiebbar sind, an jedem Endabschnitt der Seitenstege des gabelförmigen Abschnitts auf den einander zugewandten Flächen eine parallel zur Längsachse des Distanzhalters angeordnete sickenförmige Verdickung ausgebildet ist und auf der Außenfläche der Seitenstege des gabelförmigen Abschnittes des Distanzhalters in gleichem Raster zueinander augeordnete zahnförmige Vorsprünge parallel zur Längsachse des Distanzhalters ausgebildet sind.
  • c) der Fassadenhalter ist als zwischen die Seitenstege der Halteschiene oder des gabelförmigen Abschnittes des Distanzhalters schiebbares Hohlprofil mit rechteckigem oder quadratischem Querschnitt ausgebildet und weist an der Fläche der mit der Halteschiene oder dem Distanzhalter in Wirkverbindung bringbaren Seitenwände, zahnförmige Vorsprünge in einem dem Raster der zahnförmigen Vorsprünge des Distanzhalters entsprechend ausgebildeten Raster auf.

  • b) the spacer is designed as a profile body with an H-shaped cross-section, one of which has a fork-shaped section at the same distance as the side bars of the holding rail and the other fork-shaped section is designed in such a way that its side bars can be pushed between the side bars of the holding rail Each end section of the side webs of the fork-shaped section has a bead-shaped thickening which is arranged parallel to the longitudinal axis of the spacer and on the outer surface of the side webs of the fork-shaped section of the spacer is arranged in the same grid, tooth-shaped projections arranged parallel to the longitudinal axis of the spacer.
  • c) the facade holder is designed as a hollow profile with a rectangular or square cross-section which can be pushed between the side webs of the holding rail or the fork-shaped section of the spacer and has tooth-shaped projections in a grid of tooth-shaped projections on the surface of the side walls which can be operatively connected to the holding rail or the spacer Projections of the spacer on the correspondingly designed grid.

The holding rail 11 has a U-shaped cross section with two side webs 13, 14 and a transverse web 12 and is arranged vertically on the building wall 1. The spacer 15 is designed as a profile element with an H-shaped cross section. Two fork-shaped sections 16, 17 are formed on a cross piece 18 by means of side pieces 19, 20, 21, 22. The distance between the side webs 19, 20 is less than the distance between the side webs 21, 22 from each other. The side webs 19, 20 are arranged such that they can be pushed between the side webs 13, 14 of the holding rail 11. In contrast, the side webs 21, 22 are at a distance from one another which corresponds to that of the side webs 13, 14 of the holding rail. The facade holder 23 is also designed as a hollow profile and has a square cross section. The external dimensions of the facade holder 23 are designed such that it can be pushed between the side webs 21, 22 of the spacer or the side webs 13, 14 of the holding rail. A holding arm 28 can be attached to the facade holder 23 in order to achieve a butt connection with a facade panel. The holding arm 28 consists of a profile body with an L-shaped cross section and has a reinforcing rib 31 which is arranged between the holding plate 29 and the flange 30 which can be brought into operative connection with the facade holder 23.

Wie in Fig.2a und 2b dargestellt, ermöglicht der erfindungsgemäße Fassadenhalter 23 die Ausbildung eines variablen Abstandes der Fassadenplatten von der Gebäudewand 1. Der gewünschte Abstand kann durch entsprechendes Ineinanderverschieben der Halteschiene 11, des Distanzhalters 15 und der Fassadenhalters 23 erzielt werden. An der Seitenstegen 13, 14 der Halteschiene 11 sind endabschnittsseitig an den einander zugewandten Flächen 13a, 14a parallel zur Halteschienenlängsachse 32 sickenförmige Verdickungen 33a, 33b ; 34a, 34b ausgebildet. Auf den Außenflächen 19a, 20a der Seitenstege 19, 20 des gabelförmigen Abschnittes 16 des Distanzhalters 15 sind in gleichem Raster zueinander angeordnete zahnförmige Vorsprünge 38 ausgebildet, die parallel zur Längsachse 35 des Distanzhalters 15 ausgebildet sind. Beim Einschieben des gabelförmigen Abschnittes 16 zwischen die Seitenstege 13, 14 der Halteschiene 11 werden die Seitenstege 13, 14 aufgrund ihrer elastischen Eigenschaften auseinandergedrückt, so daß die endabschnittsseitigen sikkenförmigen Verdickungen 33a, 34a über die zahnförmigen Vorsprünge 38 gleiten können. Wird der vorgesehene Abstand des Distanzhalters 15 von der Gebäudewand 1 erreicht, sind die sickenförmigen Verdickungen 33a, 34a und bei genügend weitem Hineinschieben der gabelförmigen Abschnittes 16 in die Halteschiene 11 auch die sickenförmigen Verdickungen 33b, 34b mit den zahnförmigen Vorsprüngen 38 in Wirkverbindung, wodurch der Distanzhalter 15 festgeklemmt wird. In dieser Stellung kann er mittels einer Niet- oder Schraubverbindung mit den Seitenstegen 13, 14 der Halteschiene 11 verbunden werden (Fig.3). Zur Erleichterung der Verbindung des Distanzhalters 15 mit der Halteschiene 11 sind auf den den sickenförmigen Verdickungen 33a, 33b, 34a, 34b der Halteschiene 11 abgewandten Flächen 13b, 14b der Seitenstege 13, 14 längsförmig ausgebildete sickenförmige Verdickungen 41 angeordnet, die als Bohrhilfen dienen. Durch diese Verdickungen 41 ist es nicht mehr erforderlich, vor Beginn des Bohrens Maßnahmen zur Zentrierung des Bohrers vorzunehmen Insbesondere bei geringer Einschubtiefe des gabelförmigen Abschnittes 16 in die Halteschiene 11 ist es auch möglich, an den Seitenstegen 13, 14 lediglich endabschnittsseitig angeordnete sickenförmige Verdickungen 33a, 34a vorzusehen.As shown in FIGS. 2a and 2b, the facade holder 23 according to the invention enables a variable spacing of the facade panels from the building wall 1. The desired distance can be achieved by correspondingly sliding the holding rail 11, the spacer 15 and the facade holder 23 into one another. On the side webs 13, 14 of the holding rail 11, bead-shaped thickenings 33a, 33b; on the mutually facing surfaces 13a, 14a parallel to the longitudinal axis 32 of the holding rail. 34a, 34b. On the outer surfaces 19a, 20a of the side webs 19, 20 of the fork-shaped section 16 of the spacer 15, tooth-shaped projections 38 are formed in the same grid, which are parallel to the longitudinal axis 35 of the spacer 15. When inserting the fork-shaped section 16 between the side webs 13, 14 of the holding rail 11, the side webs 13, 14 are pressed apart due to their elastic properties, so that the end section-side sikkeniform thickenings 33a, 34a can slide over the tooth-shaped projections 38. If the intended distance of the spacer 15 from the building wall 1 is reached, the bead-shaped thickenings 33a, 34a and, if the fork-shaped section 16 is pushed sufficiently far into the holding rail 11, also the bead-shaped thickenings 33b, 34b are operatively connected to the tooth-shaped projections 38, as a result of which Spacer 15 is clamped. In this position, it can be connected to the side webs 13, 14 of the holding rail 11 by means of a rivet or screw connection (FIG. 3). In order to facilitate the connection of the spacer 15 to the holding rail 11, longitudinally shaped beaded thickenings 41 are provided on the surfaces 13b, 14b of the side webs 13, 14 facing away from the bead-shaped thickenings 33a, 33b, 34a, 34b of the holding rail 11, which serve as drilling aids. Due to these thickenings 41, it is no longer necessary to take measures for centering the drill before the start of drilling. In particular when the fork-shaped section 16 is not deeply inserted into the holding rail 11, it is also possible to have bead-shaped thickenings 33a, which are arranged on the side webs 13, 14, 34a to be provided.

Als Ausgleich in Fugenbereichen der Gebäudewand 1 und wenn keine besonderen Auskragungen möglich sind, können jeweils zwei einander zugewandte Endabschnitte von Fassadenhaltern 23 mittels Schiebestücken 3 miteinander verbunden sein. Diese Schiebestücke 3 werden in die Fassadenhalter 23 derart eingeführt, daß die Fassadenhalter 23 zwar parallel zu ihrer Längsachse verschieblich, radial zu dieser aber fest gelagert sind. Hierzu ist in jedem Fassadenhalter 23 (Fig. 2a) eine Schiebeführung 260 ausgebildet. An den Endabschnitten 268, 269 der Innenfläche 27a der Seitenwand 27 sind zwei Gleitflächen 265, 266 angeordnet, zwischen denen eine Ausnehmung 267 ausgebildet ist. An den Endabschnitten 261, 262 der Innenfläche 26b sind im Abstand von den Seitenwänden 24, 25 parallel zu diesen an der Seitenwand 26 zwei Führungsstege 263, 264 ausgebildet. Die Wanddicke der Seitenwand 26 ist im Bereich zwischen den Führungsstegen 263, 264 geringer als im Bereich der Endabschnitte 261, 262 zwischen den Führungsstegen 263, 264 und den Seitenwänden 24, 25. Das Schiebestück 3 wird so in den Fassadenhalter 23 eingeführt, daß der Mittelsteg 3a an den Gleitflächen 265, 266 anliegt und die dem Mittelsteg 3a abgewandten Endabschnitte der Seitenstege 3b, 3c sich zwischen den Führungsstegen 263, 264 und den Seitenwänden 24, 25 befinden. Durch die besondere Ausbildung der Schiebestückführung 260 kann ein Schiebestück 3 nur in einer Stellung in einen Fassadenhaiter23 eingeschoben werden, wodurch fehlerhafte Montagen vermieden werden.As compensation in the joint areas of the building wall 1 and if no special projections are possible, two mutually facing end sections of facade holders 23 can be connected to one another by means of sliding pieces 3. These sliding pieces 3 are inserted into the facade holder 23 in such a way that the facade holder 23 is displaceable parallel to its longitudinal axis, but is mounted radially to it. For this purpose, a sliding guide 260 is formed in each facade holder 23 (FIG. 2a). At the end sections 268, 269 of the inner surface 27a of the side wall 27, two sliding surfaces 265, 266 are arranged, between which a recess 267 is formed. Two guide webs 263, 264 are formed on the end sections 261, 262 of the inner surface 26b at a distance from the side walls 24, 25 parallel to these on the side wall 26. The wall thickness of the side wall 26 is less in the area between the guide webs 263, 264 than in the area of the end sections 261, 262 between the guide webs 263, 264 and the side walls 24, 25. The sliding piece 3 is inserted into the facade holder 23 so that the central web 3a rests on the sliding surfaces 265, 266 and the end sections of the side webs 3b, 3c facing away from the central web 3a are located between the guide webs 263, 264 and the side walls 24, 25. Due to the special design of the sliding piece guide 260, a sliding piece 3 can be inserted into a facade holder 23 only in one position, as a result of which faulty assemblies are avoided.

In den Fig. 7a und 7b ist eine als Festpunkt ausgebildete Halteschiene 11a dargestellt. Bei dieser Halteschiene 11a ist in dem Quersteg 12a ein Flächenabschnitt 12b ausgebildet, der gegenüber der Ebene des Querstegs 12a den Seitenstegen 13, 14 abgewandt vorgewölbt ist. In dem Flächenabschnitt 12b ist ein Langloch 12c ausgebildet, durch das ein Schraubbolzen zur Wandbefestigung der Hafteschiene 11a gesteckt werden kann. Zwischen den Seitenstegen 13, 14 ist ein Fassadenhalter 23 angeordnet und mittels Nietverbindungen . 44a befestigt. In den Fassadenhalter 23 ist ein Schiebestück 3 eingeschoben, das einseitig ebenfalls mit den Nietverbindungen 44a befestigt ist. Auf den freien Endabschnitt des Schiebestücks 2 ist ein weiterer Fassadenhalter 23 lediglich aufgesteckt, der auch von einer nicht näher dargestellten Halteschiene 11 a an der Gebäudewand 1 gehalten ist. Die einander zugewandten Endabschnitte 23 befinden sich in einem geringen Abstand voneinander, so daß sich der obere Fassadenhalter 23 bei thermischer Beeinflussung in Richtung der Halteschienenlängsachse 32 verschieben kann. Durch das Schiebestück 3 wird somit bei der in den Fig. 7a und 7b dargestellten Ausführung ein Gleitlager ausgebildet, durch das über die Fassadenplatten übertragene thermische Belastungen ausgeglichen werden können.7a and 7b, a holding rail 11a designed as a fixed point is shown. In the case of this holding rail 11a, a surface section 12b is formed in the crosspiece 12a, which is arched away from the side crosspieces 13, 14 opposite the plane of the crosspiece 12a. An elongated hole 12c is formed in the surface section 12b, through which a screw bolt is inserted for fastening the adhesive rail 11a to the wall can. A facade holder 23 is arranged between the side webs 13, 14 and by means of riveted connections. 44a attached. A sliding piece 3 is inserted into the facade holder 23 and is also fastened on one side with the rivet connections 44a. On the free end section of the sliding piece 2, a further facade holder 23 is simply plugged on, which is also held on the building wall 1 by a holding rail 11 a, not shown. The mutually facing end sections 23 are located at a small distance from one another, so that the upper facade holder 23 can move in the direction of the longitudinal axis 32 of the holding rail when thermally influenced. The sliding piece 3 thus forms a plain bearing in the embodiment shown in FIGS. 7a and 7b, by means of which thermal loads transmitted via the facade panels can be compensated.

Wenn die Halteschiene 11a wie auch die Halteschiene 11 als Gleitpunkt verwendet werden soll, müssen in den Seitenstegen 13, 14 langiochartige Durchbrechungen 42 vorgesehen werden. Außerdem muß jede Nietverbindung 44a dann so ausgebildet sein, daß nach Nietverformung keine zwischen Halteschiene 11a und Fassadenhalter 23 wirkenden Zwängungskräfte vorhanden sind.If the holding rail 11a and the holding rail 11 are to be used as a sliding point, elongated holes 42 must be provided in the side webs 13, 14. In addition, each rivet connection 44a must then be designed such that there are no constraining forces acting between the holding rail 11a and the facade holder 23 after the rivet deformation.

In Fig. 7c ist eine Halteschiene 11 b dargestellt, die insbesondere für horizontale Verlegung geeignet ist, was beispielsweise im Bereich von Fensterbrüstungen, Balkonen u. dgl. erforderlich sein kann. Die Halteschiene 11 b weist ebenfalls einen U-förmigen Querschnitt auf und besteht aus einem Quersteg 12d und Seitenstegen 13, 14. In dem Quersteg 12b ist mindestens ein Langloch 12e ausgebildet, dessen Längsachse 7 schiefwinklig zur Längsachse der Halteschiene 11b angeordnet ist. Wenn die Halteschiene 11 b mehrere Langlöcher 12e aufweist, sind deren Längsachsen 7 jeweils entweder parallel zueinander oder aber symmetrisch zur Senkrechten zur Halteschienenlängsachse angeordnet. Durch diese schiefwinklige Anordnung der Langlöcher 12e wird die Montage durch Vereinfachung des Ausrichtens erleichtert. Es ist auch möglich, in dem Quersteg 12d einen gegenüber der Stegebene von den Seitenstegen 13, 14 abgewandt vorgewölbten Flächenabschnitt 12f auszubilden, in dem das Langloch 12e ausgebildet wird. In diesem Fall kann das Langloch 12e auch derart angeordnet sein, daß seine Längsachse 7 senkrecht zur Längsachse der Halteschiene 11 b ausgerichtet ist, wie als Einzelheit « Z » dargestellt ist. In den Seitenstegen 13, 14 vorgesehene Durchbrechungen dienen zur Verbindung der Halteschiene 11 b mit z.B. einem horizontal anzuordnenden Abschnitt eines Fassadenhalters 23. Die Durchbrechungen können kreisrund oder langlochförmig sein.In Fig. 7c, a holding rail 11 b is shown, which is particularly suitable for horizontal laying, which for example in the area of window parapets, balconies and. Like. May be necessary. The holding rail 11b likewise has a U-shaped cross section and consists of a transverse web 12d and side webs 13, 14. At least one elongated hole 12e is formed in the transverse web 12b, the longitudinal axis 7 of which is arranged at an oblique angle to the longitudinal axis of the holding rail 11b. If the holding rail 11b has a plurality of elongated holes 12e, their longitudinal axes 7 are each arranged either parallel to one another or symmetrically to the perpendicular to the longitudinal axis of the holding rail. This oblique arrangement of the elongated holes 1 2e facilitates assembly by simplifying alignment. It is also possible to form in the transverse web 12d a surface section 12f which bulges away from the side webs 13, 14 and in which the elongated hole 12e is formed. In this case, the elongated hole 12e can also be arranged in such a way that its longitudinal axis 7 is oriented perpendicular to the longitudinal axis of the holding rail 11b, as shown as detail "Z". Openings provided in the side webs 13, 14 serve to connect the holding rail 11b to, for example, a section of a facade holder 23 to be arranged horizontally. The openings can be circular or oblong.

Die Halteschiene 11 b ohne vorgewölbten Flächenabschnitt 12f kann auch im Deckenbereich oder an Brüstungsbändern u. dgl. verwendet werden. Hierzu erfolgt die Wandbefestigung der Halteschiene 11b dann nicht mittels Schraubbolzen, sondern vorzugsweise mittels Klebeankern.The holding rail 11 b without a bulged surface section 12f can also be used in the ceiling area or on parapet strips u. Like. Be used. For this purpose, the holding rail 11b is then fastened to the wall not by means of screw bolts, but preferably by means of adhesive anchors.

Wenn nur kleine Dübelkräfte übertragen werden können wie z.B. bei nur gering belastbaren Gebäudewänden, kann die Halteschiene 11 b mit seitlichen Flanschen 6 mit mittiger Durchbrechung 6a versehen sein, durch die zusätzliche Schraubbolzen in die Gebäudewand 1 eingebracht werden können.If only small dowel forces can be transmitted, e.g. in the case of building walls which can only withstand slight loads, the holding rail 11b can be provided with lateral flanges 6 with a central opening 6a through which additional screw bolts can be introduced into the building wall 1.

An jedem Endabschnitt 21a, 22a der Seitenstege 21, 22 des gabelförmigen Abschnitts 17 des Distanzhalters 15 sind auf den einander zugewandten Flächen jeweils parallel zur Längsachse 35 des Distanzhalters 15 sickenförmige Verdickungen 36, 37 ausgebildet. Auf den Seitenwänden 24, 25 des Fassadenhalters 23 sind parallel zu dessen Längsachse 39 zahnförmige Vorsprünge 40 vorgesehen, die den gleichen Querschnitt und das gleiche Raster wie die zahnförmigen Vorsprünge 38 aufweisen. Diese zahnförmigen Vorsprünge 40 sind mit den sickenförmigen Verdickungen 36, 37 an den Seitenstegen 21, 22 des gabelförmigen Abschnitts 17 des Distanzhalters 15 sowie den gegebenenfalls zusätzlich ausgebildeten sickenförmigen Verdickungen 36a, 37a in Wirkverbindung bringbar (Fig. 4). Hierzu wird der Fassadenhalter 23 zwischen die Seitenstege 21, 22 geschoben, wobei diese sich etwas spreizen, so daß die sickenförmigen Verdickungen 36, 37 über die zahnförmigen Vorsprünge 40 gleiten können. Wenn die gewählte Einschubtiefe des Fassadenhalters 23 in den gabelförmigen Abschnitt 17 des Distanzhalters 15 erreicht ist, wird der Fassadenhalter 23 durch Klemmwirkung der Seitenstege 21, 22 in der gewünschten Lage gehalten. Hiernach kann der Fassadenhalter 23 mittels einer Niet- oder Schraubverbindung mit dem gabelförmigen Abschnitt 17 des Distanzhalters 15 verbunden werden. Zur Erleichterung der Montage ist auf den äußeren Flächen der Seitenstege 21, 22 im Abstand von den endabschnittsseitigen sickenförmigen Verdickungen 36, 37 eine kreisringförmig ausgebildete sickenförmige Verdickung 41 als Bohrhilfe ausgebildet.At each end section 21a, 22a of the side webs 21, 22 of the fork-shaped section 17 of the spacer 15, bead-shaped thickenings 36, 37 are formed on the mutually facing surfaces parallel to the longitudinal axis 35 of the spacer 15. On the side walls 24, 25 of the facade holder 23, tooth-shaped projections 40 are provided parallel to the longitudinal axis 39 thereof, which have the same cross-section and the same grid as the tooth-shaped projections 38. These tooth-shaped projections 40 can be brought into operative connection with the bead-shaped thickenings 36, 37 on the side webs 21, 22 of the fork-shaped section 17 of the spacer 15 and the optionally additionally formed bead-shaped thickenings 36a, 37a (FIG. 4). For this purpose, the facade holder 23 is pushed between the side webs 21, 22, these spread slightly, so that the bead-shaped thickenings 36, 37 can slide over the tooth-shaped projections 40. When the selected insertion depth of the facade holder 23 in the fork-shaped section 17 of the spacer 15 is reached, the facade holder 23 is held in the desired position by the clamping action of the side webs 21, 22. The facade holder 23 can then be connected to the fork-shaped section 17 of the spacer 15 by means of a rivet or screw connection. In order to facilitate assembly, an annular beading thickening 41 is formed on the outer surfaces of the side webs 21, 22 at a distance from the bead-shaped thickenings 36, 37 on the end section side as a drilling aid.

Die Fassadenplatten können direkt auf der Fläche 26 des Fassadenhalters 23 befestigt oder aber unter Verwendung von an sich bekannten L-förmigen Haltearmen 28 gehaltert werden. Der in den Fig.6a und 6b dargestellte Haltearm 28 besteht aus einer Halteplatte 29 und einem rechtwinklig zu dieser angeordneten Flansch 30, auf dem sickenförmige Verdickungen 43 im Abstand voneinander ausgebildet sind. Diese sickenförmigen Verdickungen 43 sind mit zahnförmigen Vorsprüngen 40 an den Seitenwänden 24, 25 des Fassadenhalters 23 in Wirkverbindung bringbar. Die Verbindung eines jeden Haltearms 28 mit dem Fassadenhalter 23 erfolgt mittels Schraub- oder Nietverbindungen 44, wie es bereits nach der DE-A-2639552 bekannt ist. Wenn durch Winddruck od. dgl. an den Haltearmen Biegemomente auftreten, werden die Schraub- oder Nietverbindungen 44 durch die Anlage der sickenförmigen Verdickungen 43 an den zahnförmigen Vorsprüngen 40 entlastet, die im Querschnitt spitzwinklig, trapezförmig oder halbkreisförmig ausgebildet sein können. Zur Erhöhung der Steifigkeit des Haltearmes 28 ist eine Verstärkungsrippe 31 vorgesehen, die zwischen der Halteplatte 29 und dem Flansch 30 angeordnet ist.The facade panels can be attached directly to the surface 26 of the facade holder 23 or can be held using known L-shaped holding arms 28. The holding arm 28 shown in FIGS. 6 a and 6 b consists of a holding plate 29 and a flange 30 arranged at right angles thereto, on which bead-shaped thickenings 43 are formed at a distance from one another. These bead-shaped thickenings 43 can be brought into operative connection with tooth-shaped projections 40 on the side walls 24, 25 of the facade holder 23. Each holding arm 28 is connected to the facade holder 23 by means of screw or rivet connections 44, as is already known from DE-A-2639552. If bending moments occur on the holding arms due to wind pressure or the like, the screw or rivet connections 44 are caused by the contact of the bead-shaped thickenings 43 on the tooth shaped projections 40 relieved, which can be formed at an acute angle, trapezoidal or semicircular in cross section. To increase the rigidity of the holding arm 28, a reinforcing rib 31 is provided, which is arranged between the holding plate 29 and the flange 30.

In einer weiteren Ausbildung der Halteschiene 11 sind in den Seitenstegen 13, 14 zwei im Abstand voneinander angeordnete und zueinander and zur Halteschienenlängsachse 32 parallel ausgebildete schlitzartige Durchbrechungen 42 befindlich. Durch diese Durchbrechungen 42 können die Schrauben oder Nieten geführt werden, die zur Verbindung der Halteschiene 11 mit dem Distanzhalter 15 oder dem Fassadenhalter 23 dienen (Fig.7). Durch diese schlitzartigen Durchbrechungen 42 ist es möglich, montagebedingte Ungenauigkeiten beim Aufbau der Fassadenunterkonstruktion 10 auszugleichen.In a further embodiment of the holding rail 11, two slot-like openings 42 are arranged in the side webs 13, 14 at a distance from one another and parallel to one another and parallel to the longitudinal axis 32 of the holding rail. Through these openings 42, the screws or rivets can be guided, which serve to connect the holding rail 11 to the spacer 15 or the facade holder 23 (Fig.7). These slot-like openings 42 make it possible to compensate for assembly-related inaccuracies in the construction of the facade substructure 10.

Sofern nur ein geringer Abstand der Fassadenplatten von der Gebäudewand 1 gewünscht wird, ist es auch möglich, den Fassadenhalter 23 direkt mit der Halteschiene 11 zu verbinden (Fig. 5). Bei dieser Fassadenunterkonstruktion 10a greifen die sickenförmigen Verdickungen 33a, 34a und gegebenenfalls 33b, 34b in die Zwischenräume zwischen den zahnförmigen Vorsprüngen 40 auf den Seitenwänden 24, 25 des Fassadenhalters 23 ein und halten diesen in vorbestimmter ausgerichteter Lage. Hiernach kann die endgültige Verbindung des Fassadenhalters 23 mit der Halteschiene 11 durch Schraub- oder Nietverbindungen wie oben beschrieben erfolgen.If only a small distance of the facade panels from the building wall 1 is desired, it is also possible to connect the facade holder 23 directly to the holding rail 11 (FIG. 5). In this facade substructure 10a, the bead-shaped thickenings 33a, 34a and optionally 33b, 34b engage in the spaces between the tooth-shaped projections 40 on the side walls 24, 25 of the facade holder 23 and hold it in a predetermined, aligned position. Thereafter, the final connection of the facade holder 23 to the holding rail 11 can be made by screw or rivet connections as described above.

In Fig. 8 ist ein weiterer Fassadenhalter 23a dargestellt. An den durch die Seitenwände 24, 26 ; 25, 26 gebildeten Eckabschnitten sind aus plattenförmigen Segmenten 29a bestehende Stoßprofile 28a angeformt, wobei die Ebene der plattenförmigen Segmente 29a parallel zur Ebene der Seitenwände 26, 27 angeordnet ist. Die Stoßprofile 28a kragen gegenüber der Seitenwand 26 unter Ausbildung einer Ausnehmung 26a vor, in die ein Dichtungsprofil eingelegt werden kann.Another facade holder 23a is shown in FIG. At the through the side walls 24, 26; 25, 26 formed corner sections are formed from plate-shaped segments 29a butt profiles 28a, the plane of the plate-shaped segments 29a being arranged parallel to the plane of the side walls 26, 27. The butt profiles 28a protrude from the side wall 26 to form a recess 26a into which a sealing profile can be inserted.

Der Fassadenhalter 23b nach Fig. 8a stellt eine weitere Ausgestaltung des Fassadenhalters 23a dar. In dem durch die Seitenwände 24; 25, 26, 27 gebildeten Hohlprofil ist eine Schiebestückführung 260 ausgebildet, wie sie oben bereits zu Fig. 2a beschrieben wurde. Ein Schiebestück 3 ist in dem Fassadenhalter 23b eingeführt. An den Endabschnitten der Stoßprofile 28a sind ballige Distanznocken 60a, 60b ausgebildet, um eine Hinterlüftung der zu befestigenden Fassadenplatten zu ermöglichen. Die Seitenwände 24, 25 des Fassadenhalters 23a können ebenso wie die des Fassadenhalters 23 eine kleinere Wandstärke aufweisen als die Steitenwände 26, 27.The facade holder 23b according to FIG. 8a represents a further embodiment of the facade holder 23a. In the through the side walls 24; 25, 26, 27 formed hollow profile, a sliding piece guide 260 is formed, as has already been described above for Fig. 2a. A sliding piece 3 is inserted in the facade holder 23b. Crowned spacer cams 60a, 60b are formed on the end sections of the butt profiles 28a in order to allow the facade panels to be fastened to be ventilated. The side walls 24, 25 of the facade holder 23a, like those of the facade holder 23, can have a smaller wall thickness than the side walls 26, 27.

Durch die erfindungsgemäße Fässadenunterkonstruktion 10, 10a ist somit bei Verwendung nur weniger Bauelemente eine einfache Montage von Fassadenunterkonstruktionen möglich, wobei der Abstand der Fassadenplatten von der Gebäudewand 1 einfach und leicht fest--gelegt werden kann. Durch die Verwendung nur weniger Bauelemente wird ferner die Lagerhaltung erleichtert, so daß die erfindungsgemäße Fassadenunterkonstruktion eine äußerst preisgünstige und technisch vorteilhafte Lösung darstellt.With the facade substructure 10, 10a according to the invention, simple assembly of facade substructures is thus possible when using only a few structural elements, the distance of the facade panels from the building wall 1 being simple and easy to determine. The use of only a few components also makes storage easier, so that the facade substructure according to the invention represents an extremely inexpensive and technically advantageous solution.
