Abstract

An assembly is used to space facade panels and/or facade supports from a structural support member and the assembly is made up of a support member, a dowel and an expansion screw. The support member is resilient and is provided with stop shoulders so that it can be inserted into an opening in the facade panel or facade support with the shoulders bearing against the panel or support. A dowel is inserted through and is interengaged with the support member. The dowel is inserted into a borehole in the structural support member and the expansion screw secures the dowel within the borehole.

Description

Die Erfindung betrifft ein Verfahren zur Abstandsbefestigung von Fassadenplatten bzw Fassadenträgern an Bauwerksteilen mittels im Bauwerksteil verankerbarem Dübel und in einer Durchtrittsöffnung der Fassadenplatten bzw Fassadenträger festlegbarem Stützkörper. Ferner betrifft die Erfindung einen Stützkörper und einen Dübel zur Durchführung des Verfahrens. Zur Abstandsbefestigung von Fassadenplatten bzw Fassadenträgern ist aus der DE-OS 27 12 670 eine Befestigungsanordnung mit Dübel bekannt. In letzteren wird zum Verankerungszwecke eine Spreizschraube vorgetrieben. Der auf diese Weise im Bauwerksteil festgelegte Dübel wird vom hinteren Abschnitt der Spreizschraube überragt, wobei an diesem Abschnitt die Fassadenplatte festgelegt ist. Hierzu durchragt der besagte Abschnitt die Fassadenplatte, die ihrerseits über einen Stützkörper, der in einer Durchtrittsöffnung der Fassadenplatte sitzt, am Schraubenkopf fixiert ist.The invention relates to a method for fixing the spacing of facade panels or facade supports to structural parts by means of dowels which can be anchored in the structural part and to a supporting body which can be fixed in a passage opening of the facade panels or facade supports. The invention further relates to a support body and a dowel for carrying out the method. A fastening arrangement with dowels is known from DE-OS 27 12 670 for fastening spacing of facade panels or facade supports. In the latter, an expansion screw is driven for anchoring purposes. The dowel fixed in this way in the building part is surmounted by the rear section of the expansion screw, the facade panel being fixed to this section. For this purpose, said section projects through the facade panel, which in turn is fixed to the screw head via a support body which is seated in a passage opening of the facade panel.

Ein erheblicher Nachteil dieser Befestigungsanordnung besteht darin, dass der richtige Abstand der Fassadenplatten bzw Fassadenträger zum Bauwerksteil nicht einstellbar ist. Dieses Problem ergibt sich aus unterschiedlichen Verankerungsbedingungen des Dübels, wie Durchmesserverhältnis Dübel/Aufnahmebohrung und Festigkeit des Bauwerksteiles. Dadurch muss die Spreizschraube zur Erzielung einer ausreichenden Verankerung unterschiedlich tief in den Dübel eingedreht werden. Der Schraubenkopf, über den die Fassadenplatten bzw Fassadenträger in Abstand gehalten werden, kommt demzufolge ebenso in unterschiedliche Distanz zum Bauwerksteil zu liegen.A considerable disadvantage of this fastening arrangement is that the correct distance between the facade panels or facade supports and the structural part cannot be set. This problem arises from different anchoring conditions for the anchor, such as the diameter ratio of the anchor / locating hole and the strength of the structural part. As a result, the expansion screw must be screwed into the dowel at different depths in order to achieve sufficient anchoring. The screw head, via which the facade panels or facade supports are kept at a distance, therefore also comes to lie at different distances from the building part.

Ferner ist eine Befestigungsanordnung, die sich allerdings nur für die Abstandsbefestigung relativ dickwandiger Fassadenträger eignet, bekannt. Hier kommt ein Dübel zum Einsatz, der aus einem vorderen Verankerungsabschnitt und einem hinteren Halteabschnitt für die Fassadenträger besteht. Der Dübel ragt in eine Durchtrittsöffnung der Fassadenträger ein und weist zu deren Abstützung Ringschultern auf. Nach dem Einstellen des montagerichtigen Abstandes der Fassadenträger am Bauwerksteil, was durch mehr oder weniger tiefes Einführen des Verankerungsabschnittes in eine Aufnahmebohrung des Bauwerksteiles erfolgt, wird in den im wesentlichen rohrförmigen Dübel zu dessen Verankerung eine Spreizschraube eingedreht.Furthermore, a fastening arrangement is known, which, however, is only suitable for the spacing fastening of relatively thick-walled facade supports. A dowel is used here, which consists of a front anchoring section and a rear holding section for the facade beams. The dowel protrudes into a passage opening in the facade support and has ring shoulders to support it. After setting the correct spacing of the facade supports on the structural part, which is done by inserting the anchoring section more or less deeply into a receiving bore of the structural part, an expansion screw is screwed into the essentially tubular dowel to anchor it.

Der Nachteil dieser Anordnung besteht darin, dass hohe spezifische Belastungen entstehen. Damit werden die Kontaktzonen sowohl des Dübels als auch der Fassadenträger überbeansprucht - es kommt zum Ausfall des Befestigungspunktes. Ungeeignet ist aus denselben Gründen diese Befestigungsanordnung auch für aus dünnwandigem Hohlprofil bestehende Fassadenplatten bzw Fassadenträger.The disadvantage of this arrangement is that high specific loads arise. This overstresses the contact zones of both the dowel and the facade support - the fastening point fails. For the same reasons, this fastening arrangement is also unsuitable for facade panels or facade supports consisting of thin-walled hollow profiles.

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren zur variablen Abstandsbefestigung dünnwandiger Fassadenplatten bzw Fassadenträger zu schaffen.The invention has for its object to provide a method for variable spacing thin-walled facade panels or facade supports.

Erfindungsgemäss wird die Aufgabe dadurch gelöst, dass zuerst der Stützkörper in der Durchtrittsöffnung der Fassadenplatten bzw Fassadenträger festgelegt, danach der Dübel mit dem Stützkörper verbunden und anschliessend der Dübel im Bauwerksteil verankert wird.According to the invention, the object is achieved in that the support body is first fixed in the passage opening of the facade panels or facade support, then the dowel is connected to the support body and the anchor is then anchored in the structural part.

Das Einsetzen eines Stützkörpers in die Durchtrittsöffnungen der Fassadenplatten bzw Fassadenträger, in den der Halteabschnitt eines Dübels eingeführt wird, erlaubt ein Anpassen der Befestigungsanordnung an dünnwandige Fassadenplatten bzw Fassadenträger, indem lediglich für verschiedene Wanddicken bzw Profilnormen der Fassadenplatten bzw Fassadenträger entsprechend ausgelegte Stützelemente verwendet werden.The insertion of a support body into the through openings of the facade panels or facade supports, into which the holding section of a dowel is inserted, allows the fastening arrangement to be adapted to thin-walled facade panels or facade supports, by using appropriately designed support elements for different wall thicknesses or profile standards of the facade panels or facade supports.

Nachdem der Dübel mit dem Stützkörper verbunden worden ist, wird er auf herkömmliche Weise im Bauwerksteil verankert. Einfachheitshalber handelt es sich beispielsweise um einen im wesentlichen rohrförmigen Dübel mit Verankerungsabschnitt, der in einer Aufnahmebohrung des Bauwerksteiles durch Eindrehen einer Spreizschraube verankerbar ist. Vor dem Verankerungsvorgang wird der gewünschte Abstand der Fassadenplatten bzw Fassadenträger zum Bauwerksteil eingestellt.After the dowel has been connected to the support body, it is anchored in the structural part in a conventional manner. For the sake of simplicity, it is, for example, an essentially tubular dowel with anchoring section, which can be anchored in a receiving bore of the structural part by screwing in an expansion screw. Before the anchoring process, the desired distance of the facade panels or facade beams from the building part is set.

Zur Durchführung des Verfahrens wird ferner ein Stützkörper vorgeschlagen, der Stützseiten mit Anschlagschultern für die Fassadenplatten bzw Fassadenträger aufweist. Die Anschlagschultern stützen sich an der Oberfläche der Fassadenplatten bzw Fassadenträger im Bereich der beiden Austritte der Durchtrittsöffnung ab. Für runde Durchtrittsöffnungen ist der Stützkörper hohlzylindrisch ausgebildet und die Anschlagschultern weisen zweckmässig Ringform auf. Wird die Durchtrittsöffnung hingegen von einem Längsschlitz gebildet, wie dies vor allem bei Fassadenträgern aus Hohlprofil der Fall ist, so eignen sich im wesentlichen quaderförmige Stützkörper mit leistenförmigen Anschlagschultern.To carry out the method, a support body is also proposed, the support sides with stop shoulders for the Has facade panels or facade supports. The stop shoulders are supported on the surface of the facade panels or facade supports in the area of the two exits of the passage opening. For round through openings, the support body is hollow-cylindrical and the stop shoulders expediently have a ring shape. If, on the other hand, the passage opening is formed by a longitudinal slot, as is particularly the case with facade supports made of hollow sections, then essentially cuboid support bodies with strip-shaped stop shoulders are suitable.

Vorzugsweise sind die Anschlagschultern von den beiden Stirnflächen gebildet. Insbesondere bei Fassadenträgern aus Hohlprofil lässt sich so ein sicherer formschlüssiger Halt des Stützkörpers im Hohlraum erzielen, indem sich die Anschlagschultern an die einander gegenüberliegenden Stegflächen des Hohlprofils anlegen.The stop shoulders are preferably formed by the two end faces. In particular in the case of facade supports made of hollow profile, a secure, form-fitting hold of the support body in the cavity can be achieved by the abutment shoulders resting against the opposing web surfaces of the hollow profile.

Gilt es hingegen,-dünnwandige Fassadenplatten oder blechförmige Fassadenträger zu fassen, so sind die Anschlagschultern mit Vorteil von den zueinander weisenden Flanken einer Ringnut gebildet.If, on the other hand, thin-walled facade panels or sheet-like facade supports are to be gripped, the stop shoulders are advantageously formed by the mutually facing flanks of an annular groove.

Um das Einsetzen der zweckmässig aus Kunststoff bestehenden Stützkörper in die Durchtrittsöffnung zu erleichtern, sind diese radial elastisch ausgebildet, was beispielsweise durch eine Längsschlitzung bei einem im wesentlichen hohlzylindrischen Stützkörper erreicht wird.In order to facilitate the insertion of the support bodies, which are expediently made of plastic, into the passage opening, they are designed to be radially elastic, which is achieved, for example, by a longitudinal slit in an essentially hollow cylindrical support body.

Nach einem weiteren Vorschlag der Erfindung ist die Anschlagschulter der einen Stützseite an radial federnden Segmenten des Stützkörpers angeordnet. So wird das Einführen des Stützkörpers in die Durchtrittsöffnung der Fassadenplatten bzw Fassadenträger erleichtert. Beim Einführvorgang federn die Segmente zueinander, so dass die Anschlagschultern problemlos durch die Durchtrittsöffnung geschoben werden können.According to a further proposal of the invention, the stop shoulder of one support side is arranged on radially resilient segments of the support body. This makes it easier to insert the support body into the passage opening of the facade panels or facade supports. During the insertion process, the segments spring together so that the stop shoulders can be easily pushed through the passage opening.

Hat die in Schieberichtung zweite Anschlagschulter die Durchtrittsöffnung passiert, federn die Segmente wieder auseinander und es kommt zum Hintergreifen dieser an den federnden Segmenten angeordneten Anschlagschulter an der Innenseite der vorzugsweise aus Hohlprofil bestehenden Fassadenträger.Has the second stop shoulder in the sliding direction Passing through opening, the segments spring apart again and there is an engagement behind this stop shoulder arranged on the resilient segments on the inside of the facade support, which preferably consists of a hollow profile.

Ein weiterer Vorteil für die Montage der Stützkörper wird erreicht, wenn zur Führung und zur Erzielung eines sicheren Haltes der Fassadenplatten bzw Fassadenträger Anschläge vorgesehen sind. Bei Fassadenträgern aus Hohlprofil schaffen solche Anschläge, die nach dem Einführen des Stützkörpers in die Durchtrittsöffnung einragen, eine Verschiebesicherung. Der Stützkörper hält so, unabhängig von der Einsatzlage des jeweiligen Befestigungspunktes, seine funktionsrichtige Position zur Durchtrittsöffnung bei.A further advantage for the assembly of the support bodies is achieved if stops are provided for guiding and achieving a secure hold of the facade panels or facade supports. In the case of facade supports made of hollow profiles, such stops, which protrude into the passage opening after the support body has been introduced, provide a security against displacement. The support body thus maintains its functionally correct position for the passage opening, regardless of the position of the respective attachment point.

Zur Erzielung einer guten Verbindung zwischen dem Stützkörper und dem Dübel ist eine Rasteinrichtung vorgesehen. Einfachheitshalber kann die Rasteinrichtung dübelseitig als umlaufender scharfkantiger Flansch gestaltet sein. Zu dessen Verrastung mit dem Stützkörper weist dieser eine formlich korrespondierende Rastnut auf. Eine kraftaufnahmefähigere Verrastung wird jedoch durch zwei am Halsabschnitt zueinander im Abstand angeordnete Ringschultern erreicht, deren zumindest eine sich gegen den Stützkörper anlegt.In order to achieve a good connection between the support body and the dowel, a locking device is provided. For the sake of simplicity, the locking device can be designed on the dowel side as a peripheral sharp-edged flange. To lock it with the support body, this has a formally corresponding locking groove. A more force-capable latching is achieved, however, by two annular shoulders which are arranged at a distance from one another on the neck section, at least one of which rests against the support body.

Um einen Schutz des Kopfes der Spreizschraube, insbesondere vor Korrosion, zu erreichen, wird auf den Stützkörper nach Abschluss des Befestigungsvorganges zweckmässig eine beispielsweise deckelförmige Abdeckkappe aufgesetzt. Diese kann mit Vorteil aus Kunststoff bestehen.In order to protect the head of the expansion screw, in particular against corrosion, a cover cap, for example a lid, is expediently placed on the support body after the fastening process has been completed. This can advantageously consist of plastic.

Die Erfindung wird nachstehend anhand einer Zeichnung, die Ausführungsbeispiele wiedergibt, näher erläutert. Es zeigen:

Die Figur 1 zeigt einen Fassadenträger 1, der im Abstand zu einem Bauwerksteil.2 befestigt ist. Der Fassadenträger 1 dient der Abstützung bzw Halterung einer Fassadenplatte 3, die beispielsweise durch Kleben, Schrauben oder Nieten (nicht gezeigt) mit dem Fassadenträger 1 verbunden wird.FIG. 1 shows a facade support 1, which is fastened at a distance from a structural part 2. The facade support 1 serves to support or hold a facade panel 3, which is connected to the facade support 1, for example by gluing, screwing or riveting (not shown).

Dem Befestigen des Fassadenträgers 1 dient eine Befestigungsanordnung, bestehend aus einem insgesamt mit 4 bezeichneten Stützkörper und einem insgesamt mit 5 bezeichneten Dübel, der mittels einer Spreizschraube 6 im Bauwerksteil 2 verankerbar ist.A fastening arrangement is used to fasten the facade support 1, consisting of a support body denoted overall by 4 and a dowel denoted overall by 5, which can be anchored in the building part 2 by means of an expansion screw 6.

Der Montagevorgang ist folgender: Vorerst wird in eine Durchtrittsöffnung 7 des Fassadenträgers 1 der Stützkörper 4 eingesetzt. Selbstverständlich sind im Fassadenträger 1 mehrere solcher Durchtrittsöffnungen 7 vorgesehen, in die ebenso ein Stützkörper 4 eingeführt wird. Der Stützkörper 4 weist eine Bohrung 8 auf, durch die hindurch alsdann der Dübel 5 eingeschoben wird. Dieser verrastet dabei über Ringschultern 9, 11 gegenüber dem Stützkörper 4 und wird so auch gegenüber dem Fassadenträger 1 festgelegt. Um das Durchtreten der Ringschulter 11 durch die Bohrung 8 und die Durchtrittsöffnung 7 zu erleichtern, weist der hintere Endabschnitt des Dübels 5 über den Umfang verteilt Schlitze 12 auf, wodurch der besagte Endabschnitt mit den Ringschultern 9, 11 segmentweise radial einfederbar ist. Der mit Stützkörpern 4 und Dübeln 5 bestückte Fassadenträger 1 wird alsdann in die richtige Abstandslage zum Bauwerksteil 2 gebracht, wobei der vordere Abschnitt der Dübel 5 mehr oder weniger tief in vorgefertigte Aufnahmebohrungen 13 des Bauwerksteiles 2 zu liegen kommt. Durch anschliessendes Eindrehen der Spreizschraube 6 in den Dübel 5 wird dieser in an sich bekannter Weise im Bauwerksteil 2 verankert.The assembly process is as follows: for the time being, the support body 4 is inserted into a passage opening 7 of the facade support 1. Of course, several such openings 7 are provided in the facade support 1, into which a support body 4 is also inserted. The support body 4 has a bore 8 through which the dowel 5 is then inserted. This locks over annular shoulders 9, 11 with respect to the support body 4 and is thus also fixed with respect to the facade support 1. In order for the annular shoulder 11 to pass through the bore 8 and the passage opening 7 To facilitate, the rear end portion of the dowel 5 has slots 12 distributed over the circumference, whereby the said end portion with the annular shoulders 9, 11 can be radially deflected in segments. The facade support 1 equipped with supporting bodies 4 and dowels 5 is then brought into the correct spacing position from the building part 2, the front section of the dowels 5 coming to a greater or lesser depth in prefabricated receiving bores 13 of the building part 2. By subsequently screwing the expansion screw 6 into the dowel 5, it is anchored in the building part 2 in a manner known per se.

Bei dem in Fig. 1 gezeigten Einsatzfall ist der Stützkörper 4, wie im besonderen der Fig. la entnommen werden kann, im wesentlichen hohlkegelig ausgebildet. Die Kegelfläche 14 ist auf den lichten Querschnitt der Durchtrittsöffnung 7 abgestimmt. Durch über den Umfang verteilte Schlitze 15 wird der Stützkörper 4 in Segmente 16 unterteilt, die über Stege 17 zusammengefügt bleiben. Dank der Schlitze 15 ist der Stützkörper 4 für dessen Einführvorgang radial federbar. Durch Stirnflächen gebildete Anschlagschultern 18, 19 legt sich der Stützkörper 4 an den Innenflächen des Fassadenträgers 1 in und entgegen der Einschieberichtüng fest. Ein von der Anschlagschulter 18 entgegen der Einführrichtung abragender ringförmiger Anschlag 21 greift in die Durchtrittsöffnung 7 ein und schafft seitlichen Halt.In the case of use shown in FIG. 1, the support body 4, as can be seen in particular from FIG. 1 a, is essentially of a hollow cone. The conical surface 14 is matched to the clear cross section of the passage opening 7. By means of slots 15 distributed over the circumference, the support body 4 is divided into segments 16 which remain joined together via webs 17. Thanks to the slots 15, the support body 4 is radially resilient for its insertion process. Stop shoulders 18, 19 formed by end faces fix the support body 4 on the inner surfaces of the facade support 1 in and against the insertion direction. An annular stop 21 protruding from the stop shoulder 18 against the direction of insertion engages in the passage opening 7 and creates lateral support.

Vielfach ist eine seitliche Verschiebbarkeit des Befestigungspunktes gefordert. Um dieser Anforderung zu entsprechen, werden auch Fassadenträger 1 aus Hohlprofil verwendet, die anstelle von runden schlitzförmige Durchtrittsöffnungen 7 aufweisen. Für diesen Fall ist, wie in Fig. lb gezeigt, der im wesentlichen quaderförmige Stützkörper 22 vorgesehen. Dieser besteht wiederum aus Segmenten 23, die über einen Steg 24 miteinander verbunden sind. Eine von beiden Segmenten 23 gebildete Bohrung 25 ermöglicht das Einfahren des Dübels 5. Anschlagschultern 26, 27 stützen sich an der Innenfläche des Fassadenträgers 1 ab. Seitlicher Halt wird durch einen ringförmigen Anschlag 28 erzielt, der in die längsgerichtete Durchtrittsöffnung 7 einragt.Lateral displacement of the attachment point is often required. To meet this requirement, facade supports 1 made of hollow profiles are also used, which have instead of round, slot-shaped through openings 7. In this case, as shown in FIG. 1b, the essentially cuboid support body 22 is provided. This in turn consists of segments 23 which are connected to one another via a web 24. A bore 25 formed by both segments 23 enables the dowel 5 to be retracted. Stop shoulders 26, 27 are supported on the inside area of the facade support 1. Lateral hold is achieved by an annular stop 28 which projects into the longitudinal passage opening 7.

Die in Fig. 2 gezeigte Abstandsbefestigung einer dünnwandigen Fassadenplatte 31 erfolgt wiederum mittels eines insgesamt mit 32 bezeichneten Stützkörpers und eines Dübels 5 analog der Fig. 1.The spacing fastening of a thin-walled facade panel 31 shown in FIG. 2 is again carried out by means of a support body designated overall by 32 and a dowel 5 analogous to FIG. 1.

Der in Fig. 2a verdeutlichte Stützkörper 32 setzt sich wiederum aus einzelnen Segmenten 33, die miteinander federnd verbunden sind, zusammen. Durch die Flanken einer umlaufenden Ringnut 34 sind Anschlagschultern 35, 36 gebildet, an denen sich die Ober- und Unterseite des Fassadenträgers 31 im Bereich einer runden Durchtrittsöffnung 37 abstützen. Eine Bohrung 38 im Stützkörper 32 nimmt den Dübel 5 auf. Letzterer rastet im Stützkörper 32 verschiebesicher ein, wozu die federnd gelagerten Ringschultern 9, 11 dienen. Zum Festlegen des Dübels 5 im Bauwerksteil 2 ist wiederum eine Spreizschraube 6 vorgesehen.The support body 32 illustrated in FIG. 2a is in turn composed of individual segments 33 which are connected to one another in a resilient manner. Stop shoulders 35, 36 are formed by the flanks of a circumferential annular groove 34, on which the top and bottom of the facade support 31 are supported in the region of a round passage opening 37. A bore 38 in the support body 32 receives the dowel 5. The latter snaps into the support body 32 so that it cannot move, for which purpose the spring-mounted annular shoulders 9, 11 serve. An expansion screw 6 is again provided for fixing the dowel 5 in the structural part 2.
