Abstract

The invention relates to a screed for striking off and/or smoothing fresh-concrete surfaces, having a striking-off tool (2) which can be set in vibratory or smoothing motion via a vibratory motor (7) and which can be held, such that it can move, on a drawing or actuating element (8) which is designed preferably in a handle-like manner. The striking-off tool (2) has an edge projection (4) which is essentially perpendicular to the striking-off surface and extends over the effective striking-off width.

Description

Die Erfindung bezieht sich auf eine Patsche zum Abziehen bzw. Glätten von Frischbetonoberflächen in einer Ausbildung nach dem Oberbegriff des Anspruchs 1.The invention relates to a patch for removing or smoothing fresh concrete surfaces in an embodiment according to the preamble of claim 1.

Bekannte Patschen der vorgenannten Art haben als Abziehwerkzeug plattenförmige Ziehklingen, die über den Rüttelmotor in Rüttelbewegung versetzt werden sollen. Damit kann zwar gegenüber einem manuell durchzuführenden Abziehen einer Frischbetonoberfläche ein durchaus befriedigendes Arbeitsergebnis mit vermindertem Zeitaufwand erzielt werden, jedoch erfordert dies aufgrund eines auch bei besonderer Sorgfalt unvermeidbaren Eingrabens der Ziehklinge in die Frischbetonoberfläche insbesondere in deren Seitenbereichen Korrekturarbeiten.Known slugs of the aforementioned type have plate-shaped scraper blades which are intended to be set in motion by the vibrating motor. Compared to a manual removal of a fresh concrete surface, a completely satisfactory work result can be achieved with reduced expenditure of time, but this requires correction work, particularly in the side areas thereof, because digging of the scraper blade into the fresh concrete surface is unavoidable, even with special care.

Es ist Aufgabe der vorliegenden Erfindung, eine Patsche der eingangs gennanten Art zur Verfügung zu stellen, mit der ebenfalls mit gegenüber manuellem Abziehen vermindertem Zeitaufwand ein hinsichtlich notwendiger Korrekturarbeiten verbessertes Arbeitsergebnis zu erzielen ist.It is an object of the present invention to provide a slipper of the type mentioned at the outset, with which an improved result in terms of necessary correction work can also be achieved with less time expenditure than manual removal.

Zur Lösung dieser Aufgabe zeichnet sich die Patsche der eingangs gennanten Art durch die im kennzeichnenden Teil des Anspruchs 1 angegebenen Merkmale aus. Hinsichtlich vorteilhafter Ausgestaltungen der Patsche wird auf die Ansprüche 2 bis 5 verwiesen. Durch den sich rückwärtig an vorzugsweise eine Ziehplatte sich anschließenden vertikalen und mithin hochstehenden Randansatz ist nicht nur gleichmäßig und ohne die Gefahr des Eingrabens einer Frischbetonoberfläche abzuziehen, sondern der Frischbeton zudem auch noch gleichzeitig während des Abziehvorganges zu verdichten. Das Verdichtungsmaß ist dabei auch während einer Abziehbewegung durch Winkellageveränderungen des Abziehwerkzeugs im Bereich gewisser Grenzen zu variieren.To solve this problem, the patch of the type mentioned is characterized by the in the characterizing part of the claim 1 specified characteristics. With regard to advantageous embodiments of the bump, reference is made to claims 2 to 5. Due to the vertical and consequently upstanding edge attachment, which preferably adjoins a drawing plate at the rear, not only is it possible to pull off smoothly and without the risk of digging in a fresh concrete surface, but also to compact the fresh concrete at the same time during the pulling process. The degree of compaction must also be varied within a range of certain limits during a pull-off movement by changing the angular position of the pull-off tool.

Die Patsche nach der Erfindung ist ein außerordentlich kostengünstig herzustellendes und in einfache Weise zu handhabendes Werkzeug, mit dem außerordentlich schnell auch großflächige Frischbetonflächen sauber und exakt abgezogen werden können. Aufgrund der Anordnung des Motors an dem Randansatz sind die Rüttelbewegungen nicht nur sicher und exakt zu übertragen, sondern darüber hinaus auch in einer Querrichtung, was sich nicht nur auf das Glätt- sondern auch auf das Verdichtungsergebnis postiviv auswirkt.The patch according to the invention is an extremely inexpensive to produce and easy to use tool with which even large-area fresh concrete surfaces can be removed extremely cleanly and precisely. Due to the arrangement of the motor on the edge approach, the shaking movements are not only safe and precise to transmit, but also in a transverse direction, which has a positive effect not only on the smoothing but also on the compression result.

Zur weiteren Erläuterung wird auf die Zeichnung verwiesen, in der ein Ausführungsbeispiel einer Patsche nach der Erfindung in schematischer perspektiver Darstellung gezeigt ist.For further explanation, reference is made to the drawing, in which an exemplary embodiment of a cleat according to the invention is shown in a schematic perspective illustration.

Die allgemein mit 1 bezifferte Patsche zum Abziehen hat ein allgemein mit 2 beziffertes Abziehwerkzeug an dessen plattenförmigen Grundkörper sich rückwärtig der vertikal stehende und sich über die Arbeitsbreite erstreckende Randansatz 4 angeschlossen ist. Das Abziehwerkzeug mit Abziehplatten- bzw. grundkörper 3 und Randansatz 4 ist relativ einfach durch Abwinklung bzw. Abkröpfung oder aber auch durch Anschweißung des entsprechenden Randansatzes 4 zu erstellen. In dem veranschaulichten Ausführungsbeispiel ist der Randansatz 4 zudem noch an dem plattenförmigen Abziehgrundkörper 3 über Stege 5 abgestützt. Der Randansatz 4 hat einen zentralen, geradlinig verlaufenden Mittelbereich, an dem über eine Befestigungsplatte 6 der Rüttelmotor 7 abgestützt ist. An der Platte 6 greift schwenkbeweglich das Halte- bzw. Ziehelement in Gestalt eines Stieles 8 an. An dem Stiel 8 ist ein Bedienelement 9 des Rüttelmotors 7 vorgesehen.The generally designated 1 patch for pulling off has a removal tool, generally numbered 2, to the rear of which the vertically standing edge extension 4, which extends over the working width, is connected to the plate-shaped base body. The removal tool with the removal plate or base body 3 and the edge extension 4 can be produced relatively easily by angling or angling or else by welding the corresponding edge extension 4. In the illustrated embodiment, the edge approach 4 is also supported on the plate-shaped pull-off base 3 via webs 5. The edge extension 4 has a central, straight central region, on which the vibrating motor 7 is supported via a mounting plate 6. Grips on plate 6 the holding or pulling element can be pivoted in the form of a stem 8. An operating element 9 of the vibrating motor 7 is provided on the stem 8.
