Description

Die Erfindung betrifft ein Befestigungselement mit den Merkmalen des Oberbegriffs des Anspruchs 1, eine Anordnung nach Anspruch 8 sowie ein Verfahren zum Befestigen einer Dämmstoffplatte an einem Untergrund mit den Merkmalen des Oberbegriffs des Anspruchs 9.The invention relates to a fastener with the features of the preamble of claim 1, an arrangement according to claim 8 and a method for fixing an insulation board to a substrate having the features of the preamble of claim 9.

Befestigungselemente für die Befestigung von Dämmstoffplatten sind allgemein bekannt und werden häufig auch als Dämmstoffdübel bezeichnet. Sie weisen typischerweise eine Dübelhülse, ein Spreizelement zum Verspreizen dieser Dübelhülse und einen Halteteller auf. Der Halteteller kann einstückig mit der Dübelhülse sein, aus der Druckschrift EP 0 644 301 B1 ist es jedoch beispielsweise auch bekannt, das Spreizelement einstückig bzw. fest verbunden mit dem Halteteller vorzusehen. Als Spreizelemente kommen insbesondere Schrauben, Nägel oder Schraubnägel aus Kunststoff oder Metall in Frage. Zum Verankern derartiger Befestigungselemente wird typischerweise ein Bohrloch durch die Dämmstoffplatte hindurch bis in den Untergrund erstellt. Anschließend wird das Befestigungselement in dieses Bohrloch eingeführt und die Dübelhülse durch Eintreiben des Spreizelements verspreizt. Gleichzeitig wird die Dämmstoffplatte etwas an den Untergrund herangezogen, teilweise wölbt sich die Dämmstoffplatte im Bereich des Haltetellers hierdurch etwas ein. Im Anschluss an die Befestigung der Dämmstoffplatten werden diese üblicherweise überputzt. Insbesondere bei Dünnputzen besteht das Problem, im Bereich der Befestigungselemente eine ebene Oberfläche zu erzielen. Weiterhin besteht bei manchen Befestigungselementen die Problematik der Bildung von sog. "Kältebrücken", d.h. die Befestigungselemente wirken unerwünscht als Übertragungselemente für Wärmeenergie.Fasteners for the attachment of insulation boards are well known and are often referred to as insulation dowels. They typically have a dowel sleeve, a spreading element for spreading this dowel sleeve and a retaining plate. The retaining plate may be integral with the dowel sleeve, from the document EP 0 644 301 B1 However, it is also known, for example, to provide the expansion element in one piece or fixedly connected to the retaining plate. As spreading especially screws, nails or screw nails made of plastic or metal come into question. For anchoring such fasteners, a borehole is typically created through the insulation board into the ground. Subsequently, the fastener is inserted into this hole and the dowel sleeve by driving the expansion expands. At the same time the insulation board is something used on the ground, in part, the insulation plate bulges in the region of the holding plate thereby something. Following the attachment of the insulating panels they are usually plastered over. Especially with thin plaster, there is the problem of achieving a flat surface in the area of the fastening elements. Furthermore, in some fasteners the problem of the formation of so-called. "Cold bridges", ie the fasteners act undesirable as transmission elements for heat energy.

Es ist daher seit Langem bekannt, derartige Befestigungselemente versenkt zu befestigen. Beispielsweise wird in der EP 0 086 452 B1 vorgeschlagen, die Dämmstoffplatte im Bereich des Haltetellers einige Millimeter auszufräsen, den Dübel dann wie oben beschrieben zu setzen und anschließend eine Dämmstoffrondelle in die ausgefräste Einsenkung über den Halteteller zu setzen. Die Dämmstoffrondelle schließt mit der Dämmstoffplatte ab, so dass diese einerseits gut überputzt werden kann und andererseits Kältebrücken vermieden werden.It has therefore long been known to fasten such fasteners sunk. For example, in the EP 0 086 452 B1 suggested that Cut out the insulation board in the area of the retaining plate a few millimeters, then place the anchor as described above and then place an insulating material disc in the milled recess above the retaining plate. The Dämmstofondondelle concludes with the insulation board, so that on the one hand, this can be well overpainted and on the other hand, cold bridges are avoided.

Zur Vermeidung des Ausfräsens schlägt die Druckschrift EP 1 318 250 A2 vor, die Dämmstoffplatte ringförmig einzuschneiden und den Halteteller gezielt in die Dämmstoffplatte eindringen zu lassen. Auch hier wird im Anschluss eine Dämmstoffrondelle aufgesetzt. Das ringförmige Einscheiden erfolgt mit Schneidvorrichtungen, die am Befestigungselement oder einem Sonderwerkzeug angebracht sind. Der Setzvorgang erfolgt unabhängig von der jeweils vorgeschlagenen Variante stets mit einem Spezialwerkzeug, das über einen Anschlag die Eindringtiefe des Befestigungselements in die Dämmstoffplatte vorbestimmt.To avoid the milling out beats the publication EP 1 318 250 A2 prior to cutting the insulation plate annular and let the retaining plate penetrate targeted in the insulation board. Again, a Dämmstofondondelle is attached afterwards. The annular separation takes place with cutting devices which are attached to the fastening element or a special tool. The setting process always takes place independently of the variant proposed in each case with a special tool that predetermines the penetration depth of the fastening element into the insulating panel via a stop.

Der Erfindung liegt die Aufgabe zugrunde, ein vereinfachtes Setzverfahren, ein verbessertes Befestigungselement sowie eine Anordnung mit diesem Befestigungselement vorzuschlagen.The invention has for its object to provide a simplified setting method, an improved fastener and an arrangement with this fastener.

Diese Aufgabe wird erfindungsgemäß durch das Befestigungselement nach Anspruch 1 eine Anordnung nach Anspruch 8 sowie das Verfahren nach Anspruch 9 gelöst. Überraschend hat sich gezeigt, dass es zum vertieften Setzen des Befestigungselements in einer Dämmstoffplatte genügt, wenn der Halteteller beim Verankern gedreht wird und die Kräfte auf die Dämmstoffplatte derart erhöht werden, dass der Halteteller in die Dämmstoffplatte einbricht. Dabei dringt der Halteteller in die Dämmstoffplatte ein. Durch das Drehen des Haltetellers entsteht eine Bruchkante, die zwar nicht einer idealen Zylindermantelfläche entspricht, sondern sich in Einbringrichtung leicht konisch aufweitet. Insbesondere die äußere Einbruchkante entspricht jedoch weitgehend einer Kreisform und dass sich die entstandene Einsenkung in der Dämmstoffplatte sehr gut mit einer Dämmstoffrondelle verschließen lässt. Dies ist insbesondere deshalb überraschend, weil sich herausgestellt hat, dass das vorgeschlagene Verfahren für unterschiedlichste Dämmstoffplatten, d.h. sowohl für faserige als auch durch Poren gekennzeichnete Materialien, geeignet ist. Das vorgeschlagene Verfahren benötigt somit weder am Befestigungselement noch an einem gesonderten Werkzeug Schneidvorrichtungen.This object is achieved by the fastener according to claim 1 an arrangement according to claim 8 and the method according to claim 9. Surprisingly, it has been shown that it is sufficient for recessed setting of the fastener in an insulating panel when the retaining plate is rotated during anchoring and the forces are increased on the insulation board so that the retaining plate breaks into the insulation board. The retaining plate penetrates the insulation board. By turning the holding plate creates a broken edge, which does not correspond to an ideal cylinder jacket surface, but slightly widened conically in the insertion direction. In particular, the outer break-in edge, however, largely corresponds to a circular shape and that the resulting depression in the insulation board can be very well sealed with a Dämmstoffrondelle. This is surprising in particular because it has been found that the proposed method is suitable for a wide variety of insulating panels, ie both fibrous and pore-marked materials. The proposed method thus requires neither the fastener nor a separate tool cutting devices.

Um die Verwendung jeglicher Spezialwerkzeuge zu vermeiden, ist es außerdem wichtig, dass die Eindringtiefe ohne die bekannten Anschläge an Spezialwerkzeugen vorbestimmbar ist. Die Erfindung schlägt daher vor, dass das Befestigungselement selbst ein Anschlagselement derart aufweist, dass der Halteteller beim Verankern mit definierter Eindringtiefe in die Dämmstoffplatte eindringt.In order to avoid the use of any special tools, it is also important that the penetration depth can be predetermined without the known stops on special tools. The invention therefore proposes that the fastening element itself has a stop element in such a way that the retaining plate penetrates into the insulation plate during anchoring with a defined penetration depth.

Das Anschlagselement zur Vorbestimmung der Eindringtiefe ist am Halteteller angeordnet. Vorzugsweise ist der Halteteller drehfest mit dem Spreizelement verbunden und wird mit diesem gegenüber der Dübelhülse beim Verspreizen gedreht. In einer bevorzugten Ausgestaltung ist der Halteteller außerdem nicht axial verschiebbar mit dem Spreizelement. Dies ermöglicht einen einfachen Aufbau. Das Anschlagselement zur Vorbestimmung der Eindringtiefe kann am Halteteller beispielsweise als zylindrischer Ring, der in Richtung der Dübelhülse weist, angeordnet werden. Das Befestigungselement wird im vormontierten Zustand, d.h. mit vormontiertem Spreizelement in der Dübelhülse, in das Bohrloch eingeschoben, bis das Anschlagselement auf der Außenseite der Dämmstoffplatte aufsitzt. In diesem Zustand ist die Dübelhülse noch nicht vom Spreizelement verspreizt. Das Spreizelement ist jedoch leicht eingedreht oder wird mittels einer Rasteinrichtung verliersicher in definierter Position zur Dübelhülse gehalten Durch Drehen des Haltetellers bzw. des Spreizelements wird dieses in die Dübelhülse eingezogen. Dies hat zum Einen den Effekt, dass die Dübelhülse verspreizt wird und somit Halt im Untergrund findet. Zum Anderen wird der Halteteller in Richtung der Dämmstoffplatte bewegt. Hierbei dringt zunächst das Anschlagselement in die Dämmstoffplatte ein. Sobald der Halteteller mit seinem äußeren Rand auf der Dämmstoffplatte zur Anlage kommt, erhöhen sich die Zugkräfte innerhalb des Befestigungselements. Bei entsprechend starkem Drehmoment am Spreizelement bricht der Halteteller die Dämmstoffplatte ein. Wie bei den bekannten Befestigungselementen wird der Eintreibweg des Spreizelements in die Dübelhülse dadurch begrenzt, dass eine Schulter am Spreizelement oder dgl. auf einer korrespondierenden Anschlagsfläche der Dübelhülse aufsitzt. Dies führt zu einer definierten Eindringtiefe, so dass kein Spezialwerkzeug notwendig ist.The stop element for predetermining the penetration depth is arranged on the retaining plate. Preferably, the retaining plate is rotatably connected to the expansion element and is rotated with this relative to the dowel sleeve during spreading. In a preferred embodiment, the retaining plate is also not axially displaceable with the expansion element. This allows a simple structure. The stop element for predetermining the penetration depth can be arranged on the holding plate, for example, as a cylindrical ring facing in the direction of the dowel sleeve. The fastener is in the preassembled state, i. with preassembled expansion element in the dowel sleeve, inserted into the hole until the stop element is seated on the outside of the insulation board. In this state, the dowel sleeve is not yet gespreizt from the expansion element. However, the spreader is easily screwed or captively held by means of a locking device in a defined position to the dowel sleeve By turning the retaining plate or the spreader this is fed into the dowel sleeve. This has the effect on the one hand that the dowel sleeve is spread and thus finds support in the ground. On the other hand, the holding plate is moved in the direction of the insulating board. This first penetrates the stop element in the insulation board. As soon as the retaining plate comes to rest with its outer edge on the insulating board, the tensile forces increase within the fastening element. With a correspondingly strong torque on the expansion element of the retaining plate breaks the insulation board. As in the known fasteners Eintreibweg of the expansion element in the dowel sleeve is limited by the fact that a shoulder on the expansion element or the like. Seated on a corresponding stop surface of the dowel sleeve. This leads to a defined penetration depth, so that no special tool is necessary.

Zur Bildung des erfindungsgemäßen Anschlagselements gibt es viele Alternativen. So muss das Anschlagselement weder zwingend am Haltering angeordnet noch in Form eines Ringes ausgebildet sein. Statt eines Ringes könnten auch beispielsweise einzelne säulenförmige Elemente am Halteteller angeordnet sein. Auch wäre es möglich, flächen- oder stiftartige Elemente radial abstehend am Spreizelement anzuordnen, welche beim Einschrauben des Spreizelements entweder in die Dämmstoffplatte eindringen oder in Richtung des Haltetellers umgebogen, umgeklappt oder abgebrochen werden.There are many alternatives for forming the stop element according to the invention. Thus, the stop element must not necessarily be arranged on the retaining ring or formed in the form of a ring. Instead of a ring, for example, individual columnar elements may be arranged on the retaining plate. It would also be possible to arrange surface-or pin-like elements radially projecting on the expansion element, which either penetrate when screwing in the expansion element in the insulation board or bent over in the direction of the retaining plate, folded or broken.

Ebenso gibt es für die Gestaltung des Haltetellers große Spielräume. Zum Einen muss er keine geschlossene Oberfläche aufweisen; sondern kann mehrfach durchbrochen sein. Zum Anderen ist ein äußerer Umfang zwar vorzugsweise kreisförmig, auch dies ist jedoch nicht zwingend der Fall.Likewise, there are great leeway for the design of the holding plate. For one thing, it does not have to have a closed surface; but can be broken several times. On the other hand, an outer circumference is preferably circular, but this is not necessarily the case.

In einer nicht-erfindungsgemäßen Ausführungsform könnte alternativ zu einem gesonderten Anschlagselement der Halteteller selbst als solches verwendet werden, indem er axial verschiebbar gegenüber dem Spreizelement angeordnet wird.In a non-inventive embodiment, as an alternative to a separate stop element, the holding plate itself could be used as such by being arranged to be axially displaceable relative to the spreading element.

Insbesondere bei Untergründen, die an manchen Stellen ungeeignet für eine Verankerung sind, kann es vorkommen, dass die Dübelhülse beim Verspreizen keinen ausreichenden Halt findet. In diesem Fall wird sie eventuell etwas aus dem Bohrloch gezogen, was dazu führt, dass die Eindringtiefe des Haltetellers in die Dämmstoffplatte nicht zum Einsetzen einer Dämmstoffrondelle ausreicht. Um einen in dieser Hinsicht korrekt ausgeführten Verankerungsvorgang zu visualisieren, schlägt die Erfindung vor, dass das Befestigungselement ein Kontrollelement derart aufweist, dass das Erreichen der definierten Eindringtiefe in den Dämmstoff ersichtlich wird. Vorzugsweise ist das Kontrollelement als Vorsprung am Halteteller ausgeführt, der in die der Einbringrichtung des Befestigungselements entgegengesetzte Richtung weist. Schließt dieser Vorsprung mit der Außenseite der Dämmstoffplatte ab, so signalisiert dies, dass die Mindesteindringtiefe erreicht ist. Sofern das Kontrollelement flächig am Umfang des Haltetellers im Sinne eines Teilstücks einer Zylindermantelfläche angeordnet ist, kann ohne Weiteres eine Dämmstoffrondelle eingesetzt werden. Es ist jedoch auch möglich, das Kontrollelement derart zu gestalten, dass es per Hand oder mit einem Handwerkszeug entfernbar ist, so dass keine Störgeometrien beim Einsetzen der Dämmstoffrondelle vorliegen.Especially with substrates that are unsuitable for anchoring in some places, it may happen that the dowel sleeve does not find sufficient support during spreading. In this case, it may be pulled slightly out of the borehole, with the result that the penetration depth of the retaining plate in the insulation board is not sufficient for inserting a Dämmstoffrondelle. In order to visualize a correctly executed in this respect anchoring process, the invention proposes that the fastener has a control element such that the achievement of the defined penetration depth is visible in the insulation. Preferably, the control element is designed as a projection on the holding plate, which points in the opposite direction of insertion of the fastener. If this projection closes with the outside of the insulation board, this signals that the minimum penetration depth has been reached. If the control element is arranged flat on the circumference of the retaining plate in the sense of a portion of a cylindrical surface, a Dämmstoffrondelle can be used without further notice. However, it is also possible to design the control element in such a way that it can be removed by hand or with a hand tool, so that no interfering geometries are present when the insulating material frond is inserted.

Die Erfindung wird nachfolgend anhand eines Ausführungsbeispiels erläutert. Es zeigt:

  • Figur 1 das Ausführungsbeispiel in zwei perspektivischen Schnittdarstellungen.
The invention will be explained below with reference to an embodiment. It shows:
  • FIG. 1 the embodiment in two perspective sectional views.

Das in Figur 1 dargestellte Befestigungselement 1 ist in der oberen Figurenhälfte im Zustand vor der Verspreizung und in der unteren Figurenhälfte im Zustand nach der Verspreizung dargestellt. Es dient der Befestigung einer Dämmstoffplatte 2 an einem Untergrund 3. Im Wesentlichen besteht es aus einer Dübelhülse 4, in welche zur Verankerung ein Spreizelement 5 eingeschraubt wird. An dem der Dübelhülse 4 entgegengesetzten Ende ist ein Halteteller 6 mit dem Spreizelement 5 verbunden. Grundsätzlich könnten Spreizelement 5 und Halteteller 6 einstückig sein, im vorliegenden Fall ist das Spreizelement 5 als Metallschraube mit einem Sechskantkopf 7 ausgebildet, welches eine Torx-Aufnahme 8 aufweist. Zur drehsicheren Verbindung mit dem Halteteller 6 könnte das Spreizelement 5 vom Halteteller 6 umspritzt sein. Im vorliegenden Ausführungsbeispiel ist das Spreizelement 5 in den Halteteller 6 eingesteckt, eine Sechskanteinsenkung 9, in welcher der Sechskantkopf 7 einliegt, sorgt für die Drehmomentübertragung zwischen Spreizelement 5 und Halteteller 6. Eine Sperrklinke 10 am Rand der Sechskanteinsenkung 9 bewirkt, dass das Spreizelement 5 axial im Halteteller 6 gehalten wird. Weiterhin weist der Halteteller 6 Versteifungssicken 11 auf, welche sich radial nach außen erstrecken. Der äußere Umfang 12 des Haltetellers 6 weist einen Wulst 13 mit einer im Querschnitt rechtwinkligen, in Richtung des Untergrunds 3 gewandten Außenkante 14 auf. Ebenfalls in Richtung des Untergrundes 3 erstreckt sich vom Halteteller 6 aus ein als zylindrischer Ring 15 ausgebildetes Anschlagselement. Das ringförmige Anschlagselement 15 hat in etwa den halben Durchmesser des Haltetellers 6. Es könnte aber genauso kleiner oder auch größer im Durchmesser gewählt werden. Auch bräuchte es keine vollständige Zylinderfläche aufweisen, sondern diese lediglich segmentartig andeuten. Ebenfalls in Richtung des Untergrundes 3 erstreckt sich vom Halteteller 6 aus eine das Spreizelement 5 umfassende Verlängerung 16. Diese Verlängerung 16 greift teleskopartig in eine die Dübelhülse 4 einstückig verlängernde hülsenförmige Aufnahme 17 ein. Im in der oberen Figurenhälfte dargestellten Lieferzustand des Befestigungselements 1 wird das Spreizelement 5 in der Dübelhülse 4 über eine Rastverbindung 18 zwischen der Verlängerung 16 und der Aufnahme 17 gehalten.This in FIG. 1 illustrated fastener 1 is shown in the upper half of the figure in the state before the spread and in the lower half of the figure in the state after the spread. It is used to attach an insulating plate 2 to a substrate 3. It essentially consists of a dowel sleeve 4, in which an expansion element 5 is screwed for anchoring. At the dowel sleeve 4 opposite end of a retaining plate 6 is connected to the expansion element 5. In principle, expansion element 5 and retaining plate 6 could be integral, in the present case, the expansion element 5 is formed as a metal screw with a hexagonal head 7, which has a Torx receptacle 8. For rotationally secure connection with the retaining plate 6, the expansion element 5 could be encapsulated by the retaining plate 6. In the present embodiment, the expansion element 5 is inserted into the retaining plate 6, a hexagonal recess 9, in which the hexagonal head 7 rests, ensures the torque transmission between the expansion element 5 and retaining plate 6. A pawl 10 at the edge of the hex recess 9 causes the expansion element 5 axially is held in the holding plate 6. Furthermore, the retaining plate 6 stiffening beads 11, which extend radially outward. The outer circumference 12 of the retaining plate 6 has a bead 13 with a cross-sectionally rectangular, in the direction of the substrate 3 facing outer edge 14. Also in the direction of the substrate 3 extends from the holding plate 6 from a designed as a cylindrical ring 15 stop element. The annular stop element 15 has approximately half the diameter of the retaining plate 6. It could be just as small or larger in diameter. Also, it would not have to have a complete cylindrical surface, but only indicate this segment-like. Also extending in the direction of the substrate 3 from the retaining plate 6 from an expansion element 5 comprehensive extension 16. This extension 16 telescopically engages in a dowel sleeve 4 integrally extending sleeve-shaped receptacle 17 a. In the delivery state of the fastening element 1 shown in the upper half of the figure, the expansion element 5 is held in the dowel sleeve 4 via a latching connection 18 between the extension 16 and the receptacle 17.

Zur Erstellung der Befestigung der Dämmstoffplatte 2 auf dem Untergrund 3 wird zunächst die Dämmstoffplatte 2 auf den Untergrund 3 aufgesetzt. Sie kann hierzu ggf. auf dem Untergrund 3 verklebt werden. Anschließend wird ein Bohrloch 19 durch die Dämmstoffplatte 2 hindurch bis in den Untergrund 3 erstellt. In dieses Bohrloch 19 hinein wird das Befestigungselement 1 wie in der oberen Figurenhälfte dargestellt eingesteckt, bis das Anschlagselement 15 auf der Dämmstoffplatte 2 aufsitzt. Hierdurch ist die Dübelhülse 4 bis in den Bereich des Untergrunds 3 in das Bohrloch 19 eingeschoben. Im Weiteren wird das Spreizelement 5 mit Hilfe eines Schraubwerkzeugs soweit in die Dübelhülse 4 eingetrieben, bis der in der unteren Figurenhälfte dargestellte Verankerungszustand erreicht ist. Das Schraubwerkzeug setzt hierzu vorzugsweise an der Torx-Aufnahme 8 an, je nach Stabilität des Befestigungselements 1 kann es jedoch auch an der Seckskanteinsenkung 9 ansetzen. Während des Einschraubens des Spreizelements 5 in die Dübelhülse 4 dringt zunächst das Anschlagselement 15 in die Dämmstoffplatte 2 ein. Im Weiteren setzt dann der Wulst 13 und schließlich vollflächig der gesamte Halteteller 6 auf der Dämmstoffplatte 2 auf. Durch die bereits teilweise Verspreizung der Dübelhülse 4 findet diese im Untergrund 3 bereits einen gewissen Halt. Wird das Spreizelement 5 wie vorgesehen weiter in die Dübelhülse 4 eingetrieben, so bricht die Dämmstoffplatte 2 entlang des äußeren Umfangs 12 ein. Es entsteht der in der unteren Figurenhälfte dargestellte Einbruchkegel 20. Das Eintreiben des Spreizelements 5 in die Dübelhülse 4 wird so weit fortgesetzt, bis die Verlängerung 16 des Haltetellers 6 auf einer Anschlagsfläche 21 in der Aufnahme 17 der Dübelhülse 4 aufsitzt. Ein Kontrollelement 22 zeigt dem Benutzer an, dass das Befestigungselement 1 korrekt gesetzt wurde. Es ist hierzu als Vorsprung am äußeren Umfang 12 des Haltetellers 6 angeordnet und weist vom Spreizelement 5 weg. In dem in der unteren Figurenhälfte dargestellten korrekten Verankerungszustand schließt das Kontrollelement 22 mit der Außenfläche 23 der Dämmstoffplatte 2 ab. Aufgrund seiner flachen, zylinderteilsegmentförmigen Gestaltung, nimmt es nur einen geringen Raum innerhalb des Einbruchkegels 20 ein. Hierdurch kann leicht eine nicht dargestellte beispielsweise zylindrische Dämmstoffrondelle in den Einbruchkegel 20 eingesetzt werden. Die Dämmstoffrondelle kann dabei ein leichtes Übermaß gegenüber dem äußeren Umfang 12 des Haltetellers 6 aufweisen. Hierdurch wird ein leichtes Verklemmen innerhalb des Einbruchkegels 20 erreicht. In diesem Zustand ist das Befestigungselement 1 nicht mehr sichtbar und die Außenfläche 23 der Dämmstoffplatte 2 kann problemlos überputzt werden. Für die Erstellung der Befestigung ist kein Spezialwerkzeug, sondern nur ein üblicher Bohrer und ein übliches Schraubwerkzeug, beispielsweise in Form eines Akkuschraubers, notwendig.To create the attachment of the insulation board 2 on the substrate 3, the insulation board 2 is first placed on the substrate 3. If necessary, it can be glued to the substrate 3. Subsequently, a borehole 19 is created through the insulation board 2 and into the substrate 3. In this hole 19 into the fastener 1 is inserted as shown in the upper half of the figure, until the stop element 15 is seated on the insulation board 2. As a result, the dowel sleeve 4 is pushed into the area of the substrate 3 in the borehole 19. Furthermore, the expansion element 5 is driven into the dowel sleeve 4 with the aid of a screwing tool until the anchoring state shown in the lower half of the figure is reached. For this purpose, the screwing tool preferably engages the Torx receiver 8, but depending on the stability of the fastening element 1, it can also start at the hexagonal recess 9. During screwing of the expansion element 5 in the dowel sleeve 4, the stop element 15 first penetrates into the insulation board 2 a. In addition, then sets the bead 13 and finally the entire surface of the entire holding plate 6 on the insulation board 2. Due to the already partial spreading of the anchor sleeve 4, this already has a certain hold in the background 3. If the expansion element 5 is driven further into the dowel sleeve 4 as intended, the insulation board 2 breaks along the outer circumference 12. The result is the burglary cone 20 shown in the lower half of the figure. The driving of the expansion element 5 in the dowel sleeve 4 is continued until the extension 16 of the retaining plate 6 is seated on a stop surface 21 in the receptacle 17 of the dowel sleeve 4. A control element 22 indicates to the user that the fastener 1 has been set correctly. It is arranged for this purpose as a projection on the outer circumference 12 of the retaining plate 6 and points away from the expansion element 5. In the correct anchoring state shown in the lower half of the figure concludes the control element 22 with the outer surface 23 of the insulation board 2 from. Due to its flat, cylinder-segment-shaped design, it occupies only a small space within the break-in cone 20. As a result, an unillustrated, for example, cylindrical Dämmstoffrondelle can be easily inserted into the burglary cone 20. The Dämmstofondondelle may have a slight oversize relative to the outer periphery 12 of the retaining plate 6. As a result, a slight jamming within the break-in cone 20 is achieved. In this state, the fastener 1 is no longer visible and the outer surface 23 of the insulation board 2 can be easily plastered. For the preparation of the attachment is not a special tool, but only a conventional drill and a conventional screwing, for example in the form of a cordless screwdriver necessary.
