Abstract
Eine Betonschraube mit einem Schaft (1), der: – am oberen Ende einen Schraubenkopf (10) und am unteren eine Spitze (11) hat; – eine erste Gewindespirale (12) auf dem Schaft hat, die sich vom Schraubenkopf (10) zur Spitze (11) erstreckt; und bei dem: – die dem Schraubenkopf (10) zugekehrte Seite der ersten Gewindespirale (12) in einem ersten Gewindewinkel A, der zwischen 90° und 120° liegt zum Schaft (1) steht; – die erste ne Anzahl Einkerbungen (121) hat.A concrete screw with a shaft (1) which: - has a screw head (10) at the upper end and a tip (11) at the lower end; - Has a first spiral thread (12) on the shaft, which extends from the screw head (10) to the tip (11); and in which: - the side of the first thread spiral (12) facing the screw head (10) is at a first thread angle A, which lies between 90 ° and 120 ° to the shaft (1); - Has the first ne number of notches (121).
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
- 1. Ease of screwing in and out
- 2. Precision of the screwing
Kurze Beschreibung der ZeichnungenBrief description of the drawings
Detaillierte Beschreibung der bevorzugten AusführungDetailed description of the preferred embodiment
Aus
Die oben erwähnte erste Gewindespirale (
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.
- 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.
