Description

TECHMISCHE BESCHREIBUNG ZUR KUMU-SPEZIALVERSCHRAUBUNS 1. Wirkungsweise Nach Einführung des Dübels (lGild 2) in die Aufnahmebohrung (Bild 3) wird die Schlagschraube (Bild l) bis zum Einrasten manuell eingedrückt. Durch leichte Hammerschläge wird dann die Schlagschraube weiter bis zum satten Anliegen des Schraubenkopfes auf dem Befestigungsmedium eingeschlagen. Ein Festziehen durch Drehbewegung mit Schraubenzieher nach herkömmlicher Art ist nicht erforderlich. Da die Schraubenform ab b/4 leicht konisch verläuft und die Schraubenspitze eine Rundkuppe, der Innenkörper des Dübeis jedoch ab b/4 einen spitzen, parabelförmigen Auslauf aufweist, werden 3 radial verlaufende Spannungsfelder aufgebaut, von denen sich die zwei unteren mit der Einschlagtiefe der Schraube vergrößern. Diese Spannungsfelder verkeilen Schraube-DUbel -Mauerwerk zu einer festen lösbaren Verbindung. Die Flankenform ist so gestaltet, daß ein leichtes Einführen der Schlaube ermöglicht wird (60°, siehe Einzelheit). Die Steigung "e" ist bei Dübel und Schraube gleich. Die Belastungskräfte werden nach dem Einrasten in den Planflächen der Flanken aufgenommen. Das Lösen der Verbindung ist nur durch Linksdrehung der Schlagschraube möglich. TECHMICAL DESCRIPTION OF THE KUMU SPECIAL SCREW 1. Mode of operation After inserting the dowel (Fig. 2) into the mounting hole (Fig. 3), the hammer screw is (Fig. L) pressed in manually until it clicks into place. With light hammer blows then continue with the hammer screw until the screw head is fully seated on the Fixing medium hammered in. Tightening with a twisting motion with a screwdriver conventional type is not required. Since the screw shape is slightly from b / 4 runs conically and the screw tip has a rounded tip, the inner body of the dowel but from b / 4 has a pointed, parabolic outlet, 3 are radial Tension fields built up, of which the two lower ones differ with the impact depth of the screw. These areas of tension wedge screw-DUbel masonry to a permanent detachable connection. The flank shape is designed so that a slight Insertion of the loop is made possible (60 °, see detail). The slope "e" is the same for dowel and screw. The loading forces are after locking recorded in the plane surfaces of the flanks. Loosening the connection is just through The hammer screw can be turned to the left.

2. Anwendungsgebiet Schraublose und rationelle Montage von Platten, Fliesen, Blendrahmen, Fensterrahmen, Unterkonstruktion, Verkleidung, Fassadenplatten, Decken, Lattengerippe, Regale, Schränke, Abdeckungen, Bade- und WC- Artikel, Sanitär-, Heizungs- und Elektroinstallationsteilen, Armaturen usw.2. Area of application Screwless and efficient assembly of panels, Tiles, frames, window frames, substructures, cladding, facade panels, Blankets, slatted frames, shelves, cupboards, covers, bath and toilet articles, sanitary, Heating and electrical installation parts, fittings, etc.

3. Ausführung Die Schlaeschraube (Bild 1) wird bei gleichbleibender DUbellänge (Bild 2) in verschiedenen Längen (je nach Dicke des Befestigungsmediums) ausgeführt. Die Verschraubungen werden in verschiedenen Durchmessergrößen hergestellt. Der Kopf der Schlagschraube kann je nach Verwendungszweck als Zylinder-oder Senkkopf ausgeführt werden (siehe Bild l).3. Execution The hose screw (picture 1) is constant DUbell length (Fig. 2) in different lengths (depending on the thickness of the fastening medium) executed. The screw connections are manufactured in different diameter sizes. The head of the hammer screw can be either a cylinder head or a countersunk head, depending on the intended use are carried out (see Fig. 1).

4, Werkstoff Der Dübel (Bild 2) wird aus Nylon hergestellt. Die Schlagschraube (Bild 1) wird aus einem Kunststoff hergestellt, der härter als der Dübel, aber trotzdem noch elastisch ist,4, Material The dowel (Fig. 2) is made of nylon. The impact screw (Photo 1) is made from a plastic that is harder than the dowel, but still is still elastic,
