Abstract
Description
In der Befestigungstechnik (hier Dübelfixationen) werden, von einigen Sonderheiten abgesehen, zwei Komponenten be nötigt: Dübel (= Medium zur nivellierenden/harmonisierenden Verbindung zweier verschiedener Materialien: Mineral/Metall) und die Schraube.In fastening technology (here anchor fixations), apart from a few specials, two components required: dowels (= medium for leveling / harmonizing Connection of two different materials: mineral / metal) and the screw.
Notwendig ist also eine umfassende und aufwendige Bevor ratung (Lagerhaltung) der stets passenden Teile (passende Dübel und Schrauben), von nur geringen Toleranzen abgese hen. Dies verursacht Material- und Zeitkosten.So a comprehensive and complex before is necessary Advice (warehousing) of the always fitting parts (fitting Dowels and screws), read from only small tolerances hen. This causes material and time costs.
Der im Schutzanspruch angegebenen Erfindung liegt das Problem zugrunde, eine beide Komponenten (und Aspekte) includierende Integrallösung entwickelt zu haben ("ready-to-use-solution"): Der "passende" Dübel ist stets und verfügbar, da im Aggregat (Schraube) schon integriert; dies spart Zeit (kein langes Suchen) und Geld (nur ein statt zweier Teile)The invention specified in the protection claim is Underlying problem, one of both components (and aspects) to have developed the inclusive integral solution ("ready-to-use-solution"): The "suitable" dowel is always and available because it is already integrated in the unit (screw); this saves time (no long searches) and money (only one instead of two parts)
Im Gegensatz zum "konventionellen" Dübeln können - konstruktionshalber - kleiner dimensionierte Bohrungen gewählt werden.In contrast to "conventional" dowels - for design reasons - smaller holes to get voted.
Merkantiler Vorteil: Schrauben der laufenden Produktion lassen sich technisch einfach und kostengünstig umrüsten. Die Dübelschraube besitzt vs. Dübel+Schraube geringere Dimensionen und deckt mehrere Bereiche ab (gutes bis sehr gutes Haltevermögen in Gasbeton, Ziegel, Beton).Mercantile advantage: screws in ongoing production can be converted easily and inexpensively. The dowel screw has vs. Dowel + screw less Dimensions and covers several areas (good to very good retention in gas concrete, brick, concrete).
Das Kunststoffinterponat kann aus Nylon, Teflon oder gar aus (dünnem, weichem) Drahtseil gefertigt sein (Abwägung der Gestehungskosten). - Das Inlay kann noch in sich struk turiert sein, was die Haftung verbessert (nicht stringent). The plastic interposition can be made of nylon, teflon or even be made from (thin, soft) wire rope (balancing the production costs). - The inlay can still structure itself be turiert, which improves the liability (not stringent).

Fig. III) shows the unit ( "anchor bolt") "in use" plastic Inter ponat (5) "turn up" / "surfaced" and spliced ( "secondary anchor effect") and hole wall in intimate connection / adhesion with the drilling (8) ; the thick arrows mark the directions of movement of the K.interponat ( 5 ).

Fig. IV) shows (from cranial) ("above") - the screw head has been removed - the direction of rotation (of the turns) of the K.interponat ( 5 ); free end (= contact point) ( 7 ) of the K.interponat ( 5 ); Borehole wall ( 8 ); Round arrow mark: direction of rotation of the unit ( 1 ).
Claims (1)
Im Bereich der Schraubenspitze (1a) ist das Kunsstoffinterponat nur locker adaptiert und findet hier mit seinem freien Ende (7) Kontakt zur Bohrloch wand (8) (Starterfunktion).
Nachdem das Schraubaggregat mit einer leichten Linksdrehung (entgegen dem Uhrzeigersinn) bis zur Kontaktzone eingeführt ist, wird durch das eigent liche "Eindrehen" des Aggregats das Kunsstoffinterponat - von seinem apika len (Spitze) her-"aufgedreht"; es läuft ein sukzessiver "Aufdreh"-/Aufstauch" vorgang ab, der sich zum Schraubenkopf (2) hin fortsetzt; gleichzeitig wird durch einen sich mit jeder Umdrehung verstärkenden "Spleißeffekt" die Ver bindung Aggregat/Bohrloch(wand) intensiviert ("sek. Dübeleffekt"). ("Sekundärer Dübeleffekt" also durch "drehinduzierte Augmentation"). Das Kunststoffinterponat ist an die jeweilige Schraubengröße, d. h. der korrelierenden Nuttiefe adaptiert. - Die Spleissavidität wird massgebend von dem verwendeten Material des Interponats bestimmt (Materialkonstante).It is a fastening unit (screw) provided with a plastic fit inlay / onlay ( 5 ) which is adapted to the groove and adapted to the course of the thread in a circular manner. The plastic interposition ( 5 ) following the thread ( 4 ) is firmly connected (welded) in the transition area between the shaft ( 3 ) / thread ( 4 ) with the screwing unit ( 1 ): fixation (contact) zone ( 6 ); thereby preventing the ineffective ("dead") rotation of the plastic interposition ( 5 ); furthermore, the fixation zone somewhat protruding from the screw shaft prevents the eventual. "Wandering out" of the plastic exhibit; she also owns vs. Borehole wall a certain stabilizing effect.
In the area of the screw tip ( 1 a) the plastic interposition is only loosely adapted and with its free end ( 7 ) there is contact with the borehole wall ( 8 ) (starter function).
After the screwing unit is inserted with a slight left turn (counterclockwise) to the contact zone, the actual "screwing in" of the unit causes the plastic interponate - from its apical len (tip) - "turned up"; there is a successive "unscrew" / upsetting process that continues towards the screw head ( 2 ); at the same time, the connection between the unit and the borehole (wall) is intensified by a "splicing effect" that increases with each revolution (" sec. Dowel effect "). (" Secondary dowel effect "by" rotation-induced augmentation "). The plastic interposition is adapted to the respective screw size, that is, the correlating groove depth.
