Description

Die Erfindung betrifft ein Halteelement für die Befestigung von Dämmstoffplatten gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a holding element for fastening insulation panels according to the preamble of claim 1.

Zur Befestigung von Dämmstoffplatten oder dgl. an einem Mauerwerk oder an einer Unterkonstruktion ist ein Halteelement bekannt, das einen Halteteller mit einem daran angeformten hohlen Schaft aufweist. Durch den Schaft wird ein Nagel eingeschoben und soweit in den Untergrund eingetrieben, bis der Halteteller an der Oberseite der Dämmstoffplatte zur Anlage kommt. Über den an einer Anschlagfläche im hohlen Schaft aufsitzenden Nagelkopf ist das Halteelement am Mauerwerk befestigt. Durch die zweiteilige Ausführung des bekannten Halteelementes sind zwei Arbeitsgänge zu dessen Verankerung erforderlich. Zunächst wird der Halteteller mit dem angeformten Schaft in die Dämmstoffplatte eingedrückt und anschließend der Nagel durch den Schaft hindurch in den Untergrund eingetrieben. Des weiteren muß das Ende des hohlen Schaftes erheblich verstärkt werden, um die vom Nagelkopf ausgehenden Verspannkräfte aufnehmen zu können. Schließlich ist weder der Nagelkopf noch der Nagelschaft gegen Korrosion geschützt.For fastening insulation boards or the like. To a masonry or to a substructure, a holding element is known which has a holding plate with a hollow shaft formed thereon. A nail is inserted through the shaft and driven into the subsurface until the holding plate comes into contact with the top of the insulation board. The holding element is attached to the masonry by means of the nail head seated on a stop surface in the hollow shaft. Due to the two-part design of the known holding element, two operations are required to anchor it. First, the holding plate with the molded shaft is pressed into the insulation board and then the nail is driven through the shaft into the ground. Furthermore, the end of the hollow shaft has to be strengthened considerably in order to be able to absorb the clamping forces emanating from the nail head. After all, neither the nail head nor the nail shaft is protected against corrosion.

Aus der EP-B1-074 469 ist ein Halteelement für die Befestigung von Dämmstoffplatten bekannt, bei dem der an den Halteteller angeformte Schaft an seinem dem Halteteller gegenüberliegenden Ende als Spreizdübel ausgebildet ist. Zum Festsetzen des Halteelementes in einem Untergrund wird in den Schaft und den sich daran anschließenden Spreizdübel ein der Länge des Schaftes entsprechender Nagel eingetrieben. Der Nagelkopf stützt sich zur Verspannung des Halteelementes an einer durch eine Vertiefung im Halteteller gebildeten Auflagefläche ab. Zum Schutz gegen Korrosion ist über den Nagelkopf eine Kunststoffkappe gestülpt, die den Innenraum des Schaftes nach der Montage des Halteelementes abdichtet. Auch bei diesem zweiteiligen Halteelement sind zwei Arbeitsgänge für die Montage erforderlich. Ferner kann es bei dem bekannten Halteelement zu einer vorzeitigen Spreizung kommen, die eine ausreichende Verspannung der Dämmstoffplatte über den Halteteller verhindert. In einem zu groß gebohrten Bohrloch wiederum kann aufgrund des hohen Eintreibwiderstandes des Nagels in den Spreizdübel ein zu starker Zug auf den Halteteller entstehen, der zu einem Aufbiegen des Haltetellers oder zu einem zu starken Eindrücken in die Dämmstoffplatte führen kann.From EP-B1-074 469 a holding element for fastening insulation boards is known, in which the shaft formed on the holding plate is designed as an expansion plug at its end opposite the holding plate. To fix the holding element in a subsurface, a nail corresponding to the length of the shaft is driven into the shaft and the adjoining expansion dowel. The nail head is supported for bracing the holding element on a support surface formed by a recess in the holding plate. To protect against corrosion is over the nail head put a plastic cap, which seals the interior of the shaft after the mounting of the holding element. This two-part holding element also requires two operations for assembly. Furthermore, the known holding element can lead to premature spreading, which prevents sufficient tensioning of the insulation board over the holding plate. In a borehole that is drilled too large, the high resistance to driving the nail into the expansion dowel can result in excessive pulling on the holding plate, which can lead to the holding plate being bent open or being pressed too hard into the insulation board.

Der Erfindung liegt die Aufgabe zugrunde, ein Halteelement für die Befestigung von Dämmstoffplatten zu schaffen, das eine schnelle und sichere Montage ermöglicht.The invention has for its object to provide a holding element for fastening insulation boards, which enables quick and safe installation.

Die Lösung dieser Aufgabe wird durch die im Anspruch 1 angegebenen Merkmale erreicht. Durch den mit seinem hinteren Ende in dem hohen Schaft des Halteelementes axial fixierten und im Halteteller eingebetteten Nagel ergibt sich für die Montage ein einstückiges Befestigungselement, das durch Hammerschläge auf das Zentrum des Haltetellers in einem Arbeitsgang durch die Dämmstoffplatte hindurch in ein Bohrloch des Verankerungsgrundes eingetrieben werden kann. Mit seinem die vordere Stirnseite des hohen Schaftes überstehenden Verankerungsbereich des Nagels ist dieser in jeder Position im Bohrloch festsetzbar. Damit kann die Verspannung der Dämmstoffplatte unabhängig von der Verankerung des Halteelementes im Bohrloch des Ankergrundes bestimmt werden. Damit ist das erfindungsgemäße Halteelement für die Befestigung sowohl von weichen als auch von harten Dämmstoffplatten geeignet.This object is achieved by the features specified in claim 1. The axially fixed nail with its rear end in the high shaft of the holding element and embedded in the holding plate results in a one-piece fastening element for assembly, which is driven into the borehole of the anchoring base by hammer blows on the center of the holding plate in one operation through the insulating plate can. With its anchoring area of the nail projecting from the front end of the high shaft, it can be fixed in any position in the borehole. The tension of the insulation board can thus be determined independently of the anchoring of the holding element in the borehole of the anchor base. The holding element according to the invention is thus suitable for fastening both soft and hard insulation boards.

Der bis zum Verankerungsbereich des Nagels reichende hohle Schaft weist an seinem vorderen Ende einen Bereich mit reduzierter Wandstärke auf. Dadurch entsteht eine Knautschzone, die beim Eintreiben des Halteelementes an der Bohrlochmündung aufsitzt und damit eine Abdichtung als Korrosionsschutz für den Nagel bildet.The hollow shaft, which extends to the anchoring area of the nail, has an area with reduced wall thickness at its front end. This creates a crumple zone, which sits when the holding element is driven in at the mouth of the borehole and thus forms a seal as corrosion protection for the nail.

Die Herstellung des Halteelementes kann in der Weise erfolgen, daß der Nagel mit dem Halteteller und dem Schaft umspritzt wird. Es ist allerdings auch möglich, den Nagel und das Kunststoffteil getrennt herzustellen. In diesem Fall wird der Nagel mit einem Nagelkopf ausgebildet, der zwischen einer durch eine Erweiterung des hohen Schaftes im Bereich des Haltetellers gebildeten Auflagefläche und einem in diese Erweiterung einclipsbaren Abdeckteil zur axialen Fixierung verklemmt wird. In diesem Fall ist es zweckmäßig, das einclipsbare Abdeckteil aus einem schlagfesten Kunststoff herzustellen.The holding element can be produced in such a way that the nail is extrusion-coated with the holding plate and the shaft. However, it is also possible to manufacture the nail and the plastic part separately. In this case, the nail is formed with a nail head which is clamped between a support surface formed by an extension of the high shaft in the region of the holding plate and a cover part which can be clipped into this extension for axial fixation. In this case it is expedient to produce the clip-on cover part from an impact-resistant plastic.

Ferner ist es zweckmäßig, daß der Innendurchmesser des hohen Schaftes etwas größer als der Durchmesser des Nagelschaftes ist. Durch den Spalt zwischen der Außenfläche des Nagels und der Wandung des hohen Schaftes lassen sich Temperaturdehnungen zwischen dem Verankerungsgrund und der Außenschale ausgleichen.It is also appropriate that the inner diameter of the high shaft is slightly larger than the diameter of the nail shaft. Due to the gap between the outer surface of the nail and the wall of the high shaft, temperature expansion between the anchoring base and the outer shell can be compensated.

Der Verankerungsbereich des Nagels wird durch eine U-förmige Längskerbe gebildet. Die dadurch entstehenden, radial aufgeweiteten Spreizschenkel werden beim Einschlagen des Nagels in das Bohrloch verformt bzw. nach innen gedrückt, so daß ein Reibschluß mit der Bohrlochwandung entsteht. Dieser Reibschluß kann noch zusätzlich mit an der Außenkontur des Verankerungsbereiches angeordneten Längsrippen erhöht werden.The anchorage area of the nail is formed by a U-shaped longitudinal notch. The resulting radially widened expansion legs are deformed when the nail is driven into the borehole or pressed inwards, so that a frictional connection with the borehole wall is created. This frictional engagement can additionally be increased with longitudinal ribs arranged on the outer contour of the anchoring area.

Die Erfindung wird nachfolgend anhand eines in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert.The invention is explained in more detail below with reference to an embodiment shown in the drawing.

Das Halteelement gemäß den Figuren 1 bis 4 weist einen Halteteller 1 auf, an den ein hohler Schaft 2 angeformt ist. Der vordere Bereich 3 des Schaftes 2 weist zur Bildung einer Knautschzone eine reduzierte Wandstärke auf. In dem Schaft 2 ist ein Nagel 4 eingebettet, der mit seinem Verankerungsbereich 5 die vordere Stirnseite des Schaftes 2 überragt. Dem Verankerungsbereich 5 gegenüberliegend ist der Nagel 4 mit einem Nagelkopf 6 ausgestattet, der zwischen der Auflagefläche 7 der Erweiterung 8 und einem Abdeckteil 9 zur axialen Fixierung eingeklemmt ist. Zur Halterung des Abdeckteiles 9 ist die Wandung der Erweiterung 8 mit einer Rastnut 10 versehen. Um eine höhere Flexibilität zur Aufnahme von Wärmedehnungen zu erreichen, ist der Innendurchmesser des hohen Schaftes 2 etwas größer als der Durchmesser des Nagelschaftes 4.The holding element according to FIGS. 1 to 4 has a holding plate 1, on which a hollow shaft 2 is molded. The front region 3 of the shaft 2 has a reduced wall thickness to form a crumple zone. A nail 4 is embedded in the shaft 2, and its anchoring region 5 projects beyond the front end face of the shaft 2. Opposite the anchoring area 5, the nail 4 is equipped with a nail head 6, which is clamped between the support surface 7 of the extension 8 and a cover part 9 for axial fixation. To hold the cover part 9, the wall of the extension 8 is provided with a locking groove 10. To one To achieve greater flexibility for absorbing thermal expansion, the inner diameter of the high shaft 2 is slightly larger than the diameter of the nail shaft 4.

Der Verankerungsbereich 5 des Nagels 4 wird durch eine U-förmige Längsnut 11 gebildet, die durch eine Aufkerbung hergestellt wird. Dadurch ergibt sich durch die Bildung der beiden Spreizschenkel 12 eine Art Spannhülse mit einem erweiterten Durchmesser, die beim Eintreiben in ein Bohrloch zusammengedrücktwird und damit einen Reibschluß bildet. Zur Verstärkung des Reibschlusses sind an der Außenkontur des Verankerungsbereiches 5 radial überstehende Längsrippen 13 angeordnet (siehe Figur 2).The anchoring area 5 of the nail 4 is formed by a U-shaped longitudinal groove 11, which is produced by a notch. This results from the formation of the two expansion legs 12 a kind of clamping sleeve with an enlarged diameter, which is compressed when driven into a borehole and thus forms a frictional connection. To reinforce the frictional engagement, radially projecting longitudinal ribs 13 are arranged on the outer contour of the anchoring region 5 (see FIG. 2).

In Figur 3 ist das Halteelement soweit im Bohrloch 14 des Verankerungsgrundes 15 eingetrieben, daß der Verankerungsbereich 5 bereits die volle Verankerungswirkung aufweist. Durch weiteres Eintreiben des Halteelementes erfolgt nunmehr die Verspannung der Dämmstoffplatte 16 mit dem Halteteller 1 (siehe Figur 4). Beim Eintreiben des Halteelementes wird der in seiner Wandstärke reduzierte Abschnitt 3 des Schaftes 2 an der Bohrlochmündung gestaucht, so daß sich ein Wulst 17 ausbildet. Dieser mit dem weiteren Eintreiben des Halteelementes sich vergrößernde Wulst 17 bildet eine Abdichtung an der Bohrlochmündung, die ein Eindringen von Feuchtigkeit in das Bohrloch verhindert und damit den metallischen Nagel vor Korrosion schützt.In Figure 3, the holding element is driven so far in the borehole 14 of the anchoring base 15 that the anchoring area 5 already has the full anchoring effect. By further driving in the holding element, the insulation plate 16 is now braced with the holding plate 1 (see FIG. 4). When the holding element is driven in, the section 3 of the shaft 2 which is reduced in wall thickness is compressed at the mouth of the borehole, so that a bead 17 is formed. This bead 17, which increases as the holding element is driven in, forms a seal at the mouth of the borehole, which prevents moisture from penetrating into the borehole and thus protects the metallic nail from corrosion.
