Description

Hintergrund der ErfindungBackground of the invention

(a) Bereich der Erfindung(a) Field of the invention

Die Erfindung betrifft eine Betonschraube, die nicht nur einfach herzustellen und zu verwenden ist, sondern auch eine besonders stabile Verbindung ergibt.The invention relates to a concrete screw, which is not only easy to manufacture and use, but also gives a particularly stable connection.

(b) Beschreibung des derzeitigen Standes der Technik(b) Description of the current state of the art

Herkömmliche Betonschrauben sind mit einem einfachen Schraubengewinde versehen und deshalb weder optimal für das Ein und Ausdrehen, noch ist die Verbindung besonders stabil. Wegen ihrer Sprödigkeit brechen sie bei der Montage leicht, was nicht nur zu Unbequemlichkeiten führt, sondern auch gefährlich sein kann. Außerdem bleiben sie wegen ihrer Ungleichmäßigkeiten beim Einschrauben häufig nicht senkrecht.Conventional concrete screws are provided with a simple screw thread and therefore neither optimal for turning in and out, nor is the connection particularly stable. Because of their brittleness they break easily during assembly, which not only leads to inconvenience but can also be dangerous. Moreover, they are often not vertical due to their uneven screwing.

Aus obigen Gründen sind Verbesserungen bei den folgenden Punkten nötig:

  • 1. Leichtigkeit des Ein- und Ausschraubens
  • 2. Präzision der Einschraubrichtung
For the above reasons, improvements are needed in the following points:
  • 1. Ease of screwing in and out
  • 2. Precision of the screwing

6 Vergrößerte Darstellung eines Teils des Gewindes der weiteren bevorzugten Ausführung der Erfindung 6 Enlarged view of part of the thread of the further preferred embodiment of the invention

Detaillierte Beschreibung der bevorzugten AusführungDetailed description of the preferred embodiment

Aus 1 bis 3 ersieht man, dass die erste bevorzugte Ausführung einer erfindungsgemäßen Betonschraube einen Schaft (1) mit einem Schraubenkopf (10) am oberen und einer Spitze (11) am unteren Ende sowie eine erste Gewindespirale (12) hat, welche mit einem Winkel B zwischen 16° und 23° vom Schraubenkopf (10) bis zur Spitze (11) geht. Die dem Schraubenkopf (10) zugekehrte Seite der ersten Gewindespirale (12) steht dabei in einem ersten Gewindewinkel A, der zwischen 90° und 120° liegt zum Schaft (1). Der seitliche Abstand C zwischen den Windungen der ersten Gewindespirale (12) liegt zwischen 5 mm und 20 mm. Nahe der Spitze (11) hat die erste Gewindespirale (12) eine Anzahl Einkerbungen (121) mit einer Tiefe D, die gleich der Höhe E der ersten Gewindespirale (12) ist.Out 1 to 3 it can be seen that the first preferred embodiment of a concrete screw according to the invention a shaft ( 1 ) with a screw head ( 10 ) at the top and a top ( 11 ) at the lower end and a first thread spiral ( 12 ), which with an angle B between 16 ° and 23 ° from the screw head ( 10 ) to the top ( 11 ) goes. The screw head ( 10 ) facing side of the first thread spiral ( 12 ) stands in a first Thread angle A, which lies between 90 ° and 120 ° to the shaft ( 1 ). The lateral distance C between the turns of the first thread spiral ( 12 ) is between 5 mm and 20 mm. Near the top ( 11 ) has the first thread spiral ( 12 ) a number of notches ( 121 ) having a depth D equal to the height E of the first thread spiral ( 12 ).

Die oben erwähnte erste Gewindespirale (12) geht vom Schraubenkopf (10) mit einem Winkel B von 16° bis 23° bis zur Spitze (11). Die dem Schraubenkopf (10) zugewandte Seite der ersten Gewindespirale (12) bildet dabei einen zwischen 90° und 120° liegenden ersten Gewindewinkel A zum Schaft (1). Dies erleichtert das Ein- und Ausdrehen der Betonschraube. Von der Spitze (11) ausgehend sind jeweils nach 120° Einkerbungen (121) angebracht, die die Schärfe erhöhen und die Reibung verringern. Außerdem wird die Festigkeit der Verbindung erhöht. Eine weitere Verbesserung wird durch Tempern erzielt.The above-mentioned first thread spiral ( 12 ) goes from the screw head ( 10 ) with an angle B of 16 ° to 23 ° to the top ( 11 ). The screw head ( 10 ) facing side of the first thread spiral ( 12 ) forms a lying between 90 ° and 120 ° first thread angle A to the shaft ( 1 ). This facilitates the turning in and out of the concrete screw. From the top ( 11 ) are starting in each case after 120 ° notches ( 121 ), which increase the sharpness and reduce the friction. In addition, the strength of the connection is increased. Further improvement is achieved by tempering.

5 und 6 zeigen eine weitere bevorzugte Ausführung der Erfindung. Sie hat auf dem Schaft (1) zusätzlich eine zwischen Schraubenkopf (10) und Spitze (11) verlaufende zweite Gewindespirale (13). Die zweite Gewindespirale (13) hat ein niedrigeres Profil und zudem ist dieses symmetrisch mit einem Winkel F zwischen 40° und 47°. Sie dient sowohl zur Führung der Schraube als auch zur Stabilität. 5 and 6 show a further preferred embodiment of the invention. She has on the shaft ( 1 ) in addition one between screw head ( 10 ) and tip ( 11 ) extending second thread spiral ( 13 ). The second thread spiral ( 13 ) has a lower profile and moreover it is symmetrical with an angle F between 40 ° and 47 °. It serves both to guide the screw and for stability.

Aus der Gesamtheit der Zeichnungen erkennt man, dass die erfindungsgemäße Betonschraube im Vergleich zu herkömmlichen Lösungen die folgenden Vorteile bietet:

  • 1. Der erste Gewindewinkel von zwischen 90° und 120° sorgt für ein Kraft sparendes Ein- und Ausschrauben.
  • 2. Die Einkerbungen verbessern die Schneidkraft der Betonschraube und verringern die Reibung.
  • 3. Die Verarbeitung ist gegenüber herkömmlichen Betonschrauben leichter, wodurch die Wirtschaftlichkeit erhöht wird.
  • 4. Die erfindungsgemäße Betonschraube ist durch Tempern gehärtet und daher stabiler.
  • 5. Durch zusätzlichen Einsatz einer zweiten Gewindespirale (13) wird die Fúhrung der Betonschraube verbessert und es wird eine höhere Stabilität der Verbindung erreicht.
It can be seen from the totality of the drawings that the concrete screw according to the invention offers the following advantages compared to conventional solutions:
  • 1. The first thread angle of between 90 ° and 120 ° ensures a power-saving screwing in and out.
  • 2. The notches improve the cutting force of the concrete screw and reduce friction.
  • 3. The workmanship is lighter compared to conventional concrete screws, which increases the efficiency.
  • 4. The concrete screw according to the invention is cured by annealing and therefore more stable.
  • 5. By additional use of a second thread spiral ( 13 ) improves the guidance of the concrete screw and increases the stability of the connection.
