Vorri chtung zur Befesti güng von Konsolen, Profilen und dergleichenDevice for fastening consoles, profiles and the like
Die Erfindung betrifft eine Vorrichtung gemäß der Gattung des Hauptanspruchs. The invention relates to a device according to the preamble of the main claim.
Für Montagen von abgehängten Decken, Rohren und dergleichen wird in der Regel eine aus Konsolen und/oder Profilen bestehende Unterkonstruktion verwendet. Konstruktionsbedingt oder aus Preisgrlinden bestehen diese Konsolen und Profile aus verzinktem bzw. feuerverzinktem Stahl, während die Befestigungsanker und die Unterlegscheiben aus Korrosionsschutzgründen aus rostfreiem Edelstahl hergestellt sind. Dadurch entsteht bei Montagen in feuchter Atmosphäre Kontaktkorrosiofl zwischen den beiden Materialien, die zu einer Zerstörung der Unterkonstruktia/i führt.For the installation of suspended ceilings, pipes and the like, a substructure consisting of brackets and/or profiles is generally used. Due to the design or for price reasons, these brackets and profiles are made of galvanized or hot-dip galvanized steel, while the fastening anchors and washers are made of stainless steel for corrosion protection reasons. This results in contact corrosion between the two materials when installed in a humid atmosphere, which leads to the destruction of the substructure.
Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zur Befestigung von Konsolen, Profilen und dergleichen zu schaffen, mit der eine Kontaktkorrosion verhindert wird.The invention is based on the object of creating a device for fastening brackets, profiles and the like, with which contact corrosion is prevented.
Die Lösung dieser Aufgabe wird bei einer Vorrichtung der eingangs genannten Gattung durch die im Hauptanspruch angegebenen Merkmale erreicht. Durch die Ummantelung der Berührungsflächen des Befestigungsankers und der Unterlegscheibe mit einem Kunststoff wird eine Stahl-auf-Stahl-Berührung vermieden, so daß keine Kontaktkorrosion entstehen kann.The solution to this problem is achieved in a device of the type mentioned at the beginning by the features specified in the main claim. By coating the contact surfaces of the fastening anchor and the washer with a plastic, steel-on-steel contact is avoided, so that no contact corrosion can occur.
In einer weiteren Ausführung der Erfindung ist auch die Außenkante der Unterlegscheibe.mit einem die Oberseite der Unterlegscheibe überragenden Kunststoffkragen abgedeckt, so daß auch angrenzende Berührungsflächen, die beispielsweise bei Tropfenbildung überbrückt werden könnten, gegen Kontaktkorrosion geschützt sind.In a further embodiment of the invention, the outer edge of the washer is also covered with a plastic collar that protrudes over the top of the washer, so that adjacent contact surfaces, which could be bridged, for example, in the event of droplet formation, are also protected against contact corrosion.

Die Erfindung wird nachfolgend anhand eines in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert.The invention is explained in more detail below using an embodiment shown in the drawing.
In ein Betonteil 1 ist eine Hinterschnitt-Bohrung 2 eingebracht, in die der aus einem Stehbolzen 3 und einer Spreizhülse 4 bestehende Befestigungsanker 5 eingesetzt und verspreizt wird. Nach dem Aufsetzen des mit Durchgangslöchern 6 versehenen Profils 7 über dem Befestigungspunkt wird das Profil 7 mit der mit einer Kunststoffumnprtelung 8 versehenen Unterlegscheibe ? und Hülsenmutter 10 befestigt.An undercut hole 2 is made in a concrete part 1, into which the fastening anchor 5 consisting of a stud bolt 3 and an expansion sleeve 4 is inserted and expanded. After placing the profile 7 provided with through holes 6 over the fastening point, the profile 7 is fastened with the washer ? provided with a plastic coating 8 and sleeve nut 10.
Zu diesem Zweck ist die Hülsenmutter mit einem Innengewinde 11 versehen, das auf das Außengewinde 12 des Stehbolzens 3 aufschraubbar ist. Ferner weist die Hülsenmutter einen Innensechskant 13 für das Einsetzen eines entsprechenden Werkzeuges auf.For this purpose, the sleeve nut is provided with an internal thread 11 that can be screwed onto the external thread 12 of the stud bolt 3. The sleeve nut also has a hexagon socket 13 for inserting a corresponding tool.
Die Kunststoffummantelung 8 kann in der Form ausgeführt sein, daß die Ummantelung unmittelbar auf der Hülsenmutter und Unterlegscheibe durch Aufspritzen angebracht ist. Ebenso ist es jedoch möglich, die Ummantelung durch ein gespritztes Kunststoffteil zu erreichen, in das die Unterlegscheibe 9 und gegebenenfalls auch die HUlsenmutter 10 eingepreßt sind. Durch den zwischen Profil 7 und HUlsenmutter 10 bzw. Unterlegscheibe 9 angeordneten Kunststoff wird die Kontaktkonosion zwischen Profi? und Befestigungsanker verhindert. Durch den die Oberseite der Unterlegscheibe überragenden Kunststoffkragen 14 ist auch die Außenkante der Unterlegscheibe 9 insbesondere bei Tröpfchenbildung gegen Kontaktkorrosion geschützt.The plastic coating 8 can be designed in such a way that the coating is applied directly to the sleeve nut and washer by injection molding. However, it is also possible to achieve the coating by means of an injection molded plastic part into which the washer 9 and possibly also the sleeve nut 10 are pressed. The plastic arranged between the profile 7 and the sleeve nut 10 or washer 9 prevents contact corrosion between the profile and the fastening anchor. The plastic collar 14 protruding over the top of the washer also protects the outer edge of the washer 9 against contact corrosion, particularly in the event of droplet formation.
