Description
Die Erfindung bezieht sich auf eine Befestigungseinrichtung zum Eindrehen in insbesondere einen weichen druckfesten Untergrund, wie Dämmmaterial, umfassend ein aus Kunststoff bestehendes Schraubelement mit einem zur Spitze hin sich verjüngenden Schaft sowie einem von der spitzenabgewandten Seite ausgehenden Sackloch, in dem unverdrehbar ein Gewindestift fixiert ist. The invention relates to a fastening device for screwing in particular a soft pressure-resistant substrate, such as insulating material, comprising a screw made of plastic screw with a tapering towards the tip shaft and an outgoing from the tip side blind hole in which a threaded pin is fixed non-rotatably.
Eine diesbezügliche auch als Isolierdübel zu bezeichnende Befestigungseinrichtung ist der
Um bei Befestigungen an isolierten Außenwänden oder bei Montagen im Kälte-, Klima- oder Kühlzellenaufbau zu vermeiden, dass schädliche Wärmebrücken entstehen, gelangen sogenannte Isolierdübel aus Kunststoff zum Einsatz, die in den weichen druckfesten Dämmstoff z. B. Styropor-Platten oder Hartschaumplatten eingedreht werden. Der Dübel weist eine Aushöhlung auf, in die sodann eine Schraube eingedreht wird, auf der z. B. eine Rohrschelle befestigt werden kann. Durch das Eindrehen der Schraube in den Dübel besteht die Gefahr, dass sich der Dübel mitdreht mit der Folge, dass sich dieser unerwünscht in den Untergrund eindreht. In order to avoid damaging thermal bridges when attaching to insulated exterior walls or installations in the refrigeration, air conditioning or cooling cell structure, so-called insulating plastic anchors are used, which are in the soft pressure-resistant insulating material z. B. Styrofoam plates or rigid foam plates are screwed. The dowel has a cavity, in which then a screw is screwed on the z. B. a pipe clamp can be attached. By screwing the screw into the dowel there is a risk that the dowel rotates with the result that this undesirably rotates into the ground.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Befestigungseinrichtung derart weiterzubilden, dass ein sicheres Fixieren des Gewindestifts in dem Sackloch des Schraubelementes möglich ist. The present invention has the object, a fastening device in such a way that a secure fixing of the threaded pin in the blind hole of the screw is possible.
Zur Lösung der Aufgabe sieht die Erfindung im Wesentlichen vor, dass der Gewindestift zumindest in seinem innerhalb des Schraubelements verlaufenen Bereich eine Verzahnung oder Verkeilung mit dem Klebstoff ermöglichende aufgeraute Oberfläche aufweist. In order to achieve the object, the invention essentially provides that the threaded pin has a roughened surface enabling the adhesive, at least in its region running inside the screw element.
Erfindungsgemäß ist vorgesehen, dass der innerhalb des Schraubelements verlaufende und insbesondere ein Holzgewinde aufweisende Abschnitt des Gewindestifts eine raue Oberfläche derart aufweist, dass eine Verzahnung mit dem Klebstoff möglich ist, so dass sichergestellt ist, dass die erforderliche Verbindung zwischen dem Schraubelement und dem Gewindestift in einem Umfang gegeben ist, dass eine Unverdrehbarkeit gewährleistet ist. According to the invention, the section of the threaded pin extending inside the screw element and in particular having a wood thread has a rough surface such that a toothing with the adhesive is possible so as to ensure that the required connection between the screw element and the threaded pin in one Scope is given that a Unverdrehbarkeit is guaranteed.
Hierzu ist insbesondere vorgesehen, dass die aufgeraute Oberfläche durch eine Beschichtung gebildet ist, bei der es sich insbesondere um eine Zinkschicht handelt, die durch Feuerverzinken aufgebracht ist. Somit weist der innerhalb des Schraubelementes wie Dübel verlaufende Abschnitt eine Oberflächenvergrößerung auf, die das erforderliche Verhaken des Klebstoffs mit dem Gewindestift ermöglicht, um die gewünschte Unverdrehbarkeit zu erzielen. Dabei ist insbesondere vorgesehen, dass die Dicke Schicht zwischen 15 µm und 150 µm liegt. For this purpose, it is provided in particular that the roughened surface is formed by a coating, which is in particular a zinc layer, which is applied by hot-dip galvanizing. Thus, the extending within the screw element such as dowels section has an increase in surface area, which allows the required entanglement of the adhesive with the threaded pin to achieve the desired Unverdrehbarkeit. It is particularly provided that the thickness layer is between 15 microns and 150 microns.
Vorteilhafterweise wird zum Verbinden des Gewindestifts mit dem Schraubelement ein Polyurethanklebstoff verwendet. Insbesondere sollte der Klebstoff ein oder mehrere Isocyanate enthalten. Bevorzugterweise enthält der Klebstoff 4,4‘-Methylendiphenyldiisocyanat. Advantageously, a polyurethane adhesive is used to connect the threaded pin with the screw. In particular, the adhesive should contain one or more isocyanates. Preferably, the adhesive contains 4,4'-methylene diphenyl diisocyanate.
Eigenerfinderisch wird vorgeschlagen, dass das innerhalb des Schraubelementes verlaufende Gewinde des Gewindestifts abschnittsweise widerhakenartig ausgebildet ist. Dabei ist insbesondere vorgesehen, dass das innerhalb des Schraubelements verlaufende Gewinde abschnittsweise weggedreht ist. It is self-inventively suggested that the thread of the threaded pin running within the screw element sections is formed barb-like. It is provided in particular that the thread running within the screw is partially turned away.
Ergänzend oder alternativ sieht die Erfindung vor, dass das innerhalb des Schraubelements verlaufende Gewinde zumindest abschnittsweise von zumindest einer in Längsrichtung des Gewindestifts verlaufende Vertiefung wie Nut unterbrochen ist. Additionally or alternatively, the invention provides that the thread running within the screw element is interrupted at least in sections by at least one recess extending in the longitudinal direction of the threaded pin, such as a groove.
Weitere Einzelheiten, Vorteile und Merkmale der Erfindung ergeben sich nicht nur aus den Ansprüchen, den diesen zu entnehmenden Merkmalen – für sich und/oder in Kombination –, sondern auch aus der nachfolgenden Beschreibung eines der Zeichnung zu entnehmenden bevorzugten Ausführungsbeispiels. Further details, advantages and features of the invention will become apparent not only from the claims, the features to be taken these features - alone and / or in combination - but also from the following description of a drawing to be taken preferred embodiment.

Als Klebstoff zum zusätzlichen Fixieren hat sich insbesondere ein Klebstoff auf Polyurethan-Basis bewährt. Vorzugsweise sollte der Klebstoff 4,4‘-Methylendiphenyldiisocyanat enthalten. As an adhesive for additional fixing in particular a polyurethane-based adhesive has been proven. Preferably, the adhesive should contain 4,4'-methylene diphenyl diisocyanate.
