Die Erfindung betrifft einen Metalldübel mit einem Innenge winde zum Eindrehen einer Schraube, die eine Spreizfunktion und/oder eine Knickfunktion bewirkt. Derartige Metalldübel sind in den verschiedensten Ausführungsformen bekanntgeworden. So sind beispielsweise Spreizdübel aus Messing bekannt, bei denen die mit Innengewinde versehene Schafthülse mit Längs schlitzen versehen ist, derart, daß beim Eindrehen der Schraube eine Spreizwirkung zustandekommt, durch die der Dübel sicher und dauerhaft in einem Bohrloch festgelegt werden kann.The invention relates to a metal dowel with a Innenge winch to screw in a screw that has a spreading function and / or causes a kink function. Such metal dowels have become known in various embodiments. For example, brass expansion anchors are known for which the shaft sleeve with internal thread provided with longitudinal slits is provided, such that when screwing in the screw a spreading effect occurs through which the dowel is secure and can be permanently set in a borehole.
Bei anderen bekannten Metalldübeln ist das Innengewinde in einer Hülse am Dübelfuß angeordnet, wodurch beim Eindrehen einer Schraube eine axiale Stauchung des an den Dübelfuß ansetzenden Schaftes bewirkt wird, der im Dübelloch auf spreizt oder in einem Hohlblockstein oder hinter einer Wand platte ausknickt und sich gegebenenfalls verknotet.In other known metal dowels, the internal thread is in a sleeve is arranged on the dowel foot, so when screwing in a screw an axial compression of the dowel foot attaching shaft is caused in the dowel hole spreads or in a hollow block or behind a wall plate bends and knotted if necessary.
Bekannt sich auch Metalldübel, bei denen an eine massive Ge windehülse am Dübelfuß mehrere aus Blech bestehende halb zylindrische Schafthälften integral angeformt sind, die bei axialer Verspannung nach außen aufspreizen oder ausknicken. Ein Beispiel eines solchen Metallblechdübels zeigt die GB 2 191 838 A.Also known is metal dowels, in which a massive Ge wind sleeve on the dowel foot several half made of sheet metal cylindrical shaft halves are integrally formed, which at Spread out or buckle the axial bracing outwards. An example of such a sheet metal dowel shows the GB 2 191 838 A.
Die nachveröffentlichte ältere Anmeldung DE 196 30 782 A1 zeigt einen derartigen Metalldübel, bei dem der Schaft aus zwei halbzylinderförmig ausgebildeten Schaftschalen besteht, die diametral gegenüberliegend am Rand der Gewindehülse ein stückig angeformt und an den freien Schaftenden zusammen geführt sind. Die Schaftschalen weisen vom Schafthals radial nach außen abgewinkelte Lappen zur Anlage des Dübels am Rand eines Dübelloches auf. Die Schaftschalen weisen mehrere nach außen aufspreizbare Stege auf, die schraubenförmig ge wendelt sind.The later published older application DE 196 30 782 A1 shows such a metal dowel, in which the shaft consists of two semi-cylindrical shaft shells, which diametrically opposite at the edge of the threaded sleeve integrally formed and together at the free shaft ends are led. The shaft cups point radially from the shaft neck outward-angled rag to attach the dowel to Edge of a dowel hole. The shaft shells have several outwardly expandable webs that are helical are spiraling.
Die US-A-2 396 501 zeigt einen Metalldübel mit einer Gewinde hülse, an der zwei oder drei Schaftschalen ansetzen, die bei axialer Verspannung hinter der Wand ausknicken und so eine Abstützung und Festlegung bewirken sollen.US-A-2 396 501 shows a metal dowel with a thread sleeve, attach to the two or three shaft shells, the at Buckle axial tension behind the wall and create one Support and determination should effect.
Ein weiterer Metalldübel dieser Gattung ist in der US-A- 2 538 601 beschrieben. Hier sind an eine Gewindehülse zwei Schaftstege angeformt, die diametral gegenüberliegend in das in einer Wand eingebohrte Loch eingesetzt und durch Eindrehen einer Schraube hinter der Wand nach außen ausgeknickt werden. Um das Ausknicken an einer vorbestimmten Stelle im Mittelab schnitt der Schaftstege zu gewährleisten, sind an dieser Stelle in den Schaftstegen Schwächungsstellen in Gestalt von Einprä gungen vorgesehen.Another metal dowel of this type is in the US-A- 2 538 601. Here are two on a threaded sleeve Shaped webs that are diametrically opposite in the hole drilled in a wall and screwed in be screwed outwards behind a wall. About the buckling at a predetermined location in the middle To ensure the cut of the shaft webs are at this point weakening points in the form of impressions in the shaft webs provisions provided.
Bei dem in der US-A-3 381 566 beschriebenen Metalldübel sind an eine Gewindehülse zwei, drei, vier oder fünf Stege ange formt, die durch schraubenlinienförmige Schlitze getrennt sind und im Ursprungszustand einen nur durch die Schlitze unterbrochenen Schaft bilden. Bei axialer Verspannung ver knoten sich die schraubenlinienförmig verlaufenden Schaftstege hinter der Wand.The metal dowel described in US-A-3,381,566 attached to a threaded sleeve two, three, four or five webs forms that are separated by helical slots are and in the original state only through the slots form an interrupted shaft. With axial bracing ver knot the helical shaft webs behind the wall.
Die Erfindung bezieht sich auf derartige Metallblechdübel mit massivem Gewindefuß mit Innengewinde, die universell einsetz bar sind und je nach Beschaffenheit des Werkstoffs, in den sie eingesetzt sind, und je nach Beschaffenheit des Bohrloches als Spreizdübel oder als Knickdübel wirksam sind. The invention relates to such sheet metal dowels solid threaded foot with internal thread that can be used universally bar and depending on the nature of the material in which they are used, and depending on the nature of the borehole are effective as expansion dowels or as kink dowels.
Bei allen diesen bekannten Metalldübeln war das Innengewinde im Dübelfuß auf einen bestimmten Schraubendurchmesser und ein bestimmtes Schraubgewinde, meist ein metrisches Gewinde, abge stimmt. Es mußten daher Dübel nicht nur für unterschiedliche Schraubendurchmesser, sondern darüberhinaus auch für unter schiedliche Schraubgewindeformen zur Verfügung gehalten werden.The internal thread of all these known metal dowels was in the dowel foot to a certain screw diameter and a certain screw threads, usually a metric thread, abge Right. Therefore dowels had to be used not only for different ones Screw diameter, but also for under different screw thread forms are available.
Der Erfindung liegt daher die Aufgabe zugrunde, einen Metall dübel zu schaffen, der universell verwendbar ist.The invention is therefore based on the object of a metal to create dowels that can be used universally.
Gelöst wird die gestellte Aufgabe durch die Gesamtheit der im Patentanspruch 1 angegebenen Merkmale. Die zwei ineinandergrei fenden Gewindegänge sind vorzugsweise zylindrisch ausgebildet und weisen den gleichen Gewindedurchmesser auf.The task is solved by the totality of the Claim 1 specified features. The two intertwined fenden threads are preferably cylindrical and have the same thread diameter.
Die DD-PS 145 654 zeigt zwar die Überlagerung eines Innenge windes mit großer Steigung durch ein Innengewinde mit kleiner Steigung, wobei das Gewinde großer Steigung ein Trapezgewinde ist und das Gewinde mit kleiner Steigung ein metrisches Ge winde. Diese einander überlagernden Gewinde sind aber in einer Verbindungsmuffe eingearbeitet, die zur axialen Verbindung von Stäben mit unterschiedlichen Gewindearten dient. Ein Stab mit einer ersten Gewindeart wird von der einen Seite in die Muffe eingeschraubt und ein Stab mit einer zweiten Gewindeart wird in das andere Ende der Muffe eingeschraubt. Demgegenüber handelt es sich beim Erfindungsgegenstand um einen speziell ausgebil deten Metalldübel, bei dem die eine axiale Verspannung des Schaftes ermöglichende Gewindehülse dazu bestimmt ist, ent weder eine Schraube mit dem einen Gewinde oder eine Schraube mit einem anderen Gewinde aufzunehmen, wobei die Schrauben von einer Seite her in die Gewindehülse einschraubbar sind.The DD-PS 145 654 shows the superimposition of an internal ge winds with a large pitch due to an internal thread with a small one Pitch, the thread of large pitch a trapezoidal thread and the thread with a small pitch is a metric Ge wind. These overlapping threads are in one Connection sleeve incorporated for the axial connection of Bars with different thread types. A staff with A first type of thread is in the sleeve from one side screwed in and a rod with a second thread type is in screwed in the other end of the sleeve. Acting against it the subject matter of the invention is specially trained Deten metal dowels, in which the axial bracing of the Shank enabling threaded sleeve is intended to ent neither a screw with one thread or a screw with a different thread, taking the screws can be screwed into the threaded sleeve from one side.
Es hat sich gezeigt, daß bei entsprechendem Wanddurchmesser der Gewindehülse und geeigneter Materialwahl eine axiale Ver spannung über wenigstens zwei unterschiedliche Gewindegänge erfolgen kann, beispielsweise und vorzugsweise über ein metrisch ausgebildetes Gewinde und über ein Spanplattenge winde. Für derartige Gewinde sind die meisten bisher bekannten Metalldübel bestimmt, die disher bei jedem Gewindedurchmesser in unterschiedlicher Ausbildung für Maschinenschrauben und Spanplattenschrauben gefertigt wurden.It has been shown that with a corresponding wall diameter the threaded sleeve and a suitable choice of material an axial Ver tension over at least two different threads can take place, for example and preferably via a metric thread and a particle board wind. Most of the hitherto known are for such threads Metal dowels determined that disher with any thread diameter in different training for machine screws and Chipboard screws were made.
Die Erfindung ist jedoch nicht beschränkt auf die Ausbildung dieser beiden Gewinetypen, sondern kann beispielsweise auch Anwendung finden für Whitworth-Gewinde (Zollgewinde), kombi niert mit einem TWIN-FAST-Gewinde.However, the invention is not limited to training of these two types of wins, but can also, for example Find application for Whitworth threads (inch thread), comb with a TWIN-FAST thread.
Dabei können auch unterschiedliche Zahnformen, unterschied liche Steigungen und unterschiedliche Gewindeflanken Verwen dung finden, beispielsweise Trapezgewinde, Sägengewinde, Rund gewinde oder andere bekannte Gewinde.Different tooth shapes can also be different Use gradients and different thread flanks Find, for example, trapezoidal thread, saw thread, round thread or other known thread.
Es können sogar zwei Gewinde mit unterschiedlichem Durchmes ser in die Gewindehülse eingeschnitten werden, indem man bei spielsweise ein zweites Gewinde mit kleinerem Durchmesser und kleinerer Steigerung in die Gewindezähne eines äußeren Gewin des einschneidet.There can even be two threads with different diameters water can be cut into the threaded sleeve by using for example a second thread with a smaller diameter and small increase in the thread teeth of an external thread the cuts.
Sämtliche denkbaren Kombination en von Gewindeformen und Arten sollen für die Erfindung vorbehalten bleiben. Bedingung ist lediglich, daß die beiden übereinanderliegenden Gewinde je weils für sich allein die erforderliche Längsverspannung über die Preßflanken gewährleisten. Um die erforderliche Längsver spannung zu gewährleisten, ist es zweckmäßig, die Gewindehülse massiv und aus einem entsprechend widerstandsfähigen Material auszubilden.All conceivable combinations of thread shapes and types should be reserved for the invention. condition is only that the two superimposed threads each because alone the required longitudinal tension over ensure the press flanks. To the required longitudinal ver To ensure tension, it is advisable to use the threaded sleeve solid and made of a correspondingly resistant material to train.
