Rüttel- Vorsatzwerkzeug für elektrische Bohrhämmer und Meißel hammer mit pneumatischem Schlagwerk zum Verdichten von Beton.Vibrating attachment tool for electric hammer drills and chisel hammers with pneumatic impact mechanism for compacting concrete.

Beim Betongießen in Formschalungen werden zur .mögl i chst blasenfreien Verdichtung des Betons elektrische Vibrationsverdichter (Rüttelflasche) eingesetzt. Eine einfachere Methode ist bei kleineren Flächen das Klopfen mit dem Hammer auf die Schalung. Die Schiagfrequenz ist hierbei nichtsehr hoch, sodaß der gewünschte Rütteleffekt nur sehr mühsam und unvollkommen erreicht wird.When pouring concrete into formwork, electric vibration compactors (vibrator bottles) are used to compact the concrete as bubble-free as possible. A simpler method for smaller areas is to tap the formwork with a hammer. The impact frequency is not very high, so the desired vibration effect is only achieved with great effort and incompletely.

Der Erfindung liegt die Aufgabe zugrunde, eine Rüttelvorrichtung zu schaffen, die mit hoher Schlagfolge kräfteschonend auf das Schalungsmaterial einwirkt, um eine gute Verdichtung des Betons zu gewährleisten, besonders bei Sichtbeton.The invention is based on the object of creating a vibrating device that acts on the formwork material with a high impact rate in a force-saving manner in order to ensure good compaction of the concrete, especially in the case of exposed concrete.

Die Lösung dieser Aufgabe ist ein Vorsatzwerkzeug für Bohrhämmer oder Meißel hammer, das es möglich macht, die hochfrequente Schlagenergie aus dem Schlagwerk der Maschine auf das Schalungsmaterial zu übertragen. Das Vorsatzwerkzeug ist mit dem Schaft am hinteren Ende in den Werkzeughalter der Maschine einsetzbar. Das vordere Ende ist kegelförmig verstärkt und besitzt eine konvex geformte Schiagf1äche.The solution to this problem is an attachment tool for rotary hammers or chisel hammers, which makes it possible to transfer the high-frequency impact energy from the machine's impact mechanism to the formwork material. The attachment tool can be inserted into the machine's tool holder with the shaft at the rear end. The front end is conically reinforced and has a convex impact surface.

Mit der Erfindung ist eine gute Zeit und Kraft sparende Betonverdichtung möglich, insbesondere bei Sichtbeton an Brüstungen, Säulen, Stürzen usw..The invention enables good, time- and effort-saving concrete compaction, especially for exposed concrete on parapets, columns, lintels, etc.
