Description

Verfahren zum Ausfüllen von Rissen in Betondecken und Belagbeton Wenn an der Oberfläche sichtbare Risse in Betonschichten ausgefüllt werden sollen, um die unschön: aussehenden Risse nicht augenfällig zu machen oder um *zu verhindern:, daß Flüssigkeiten in das Gefüge des Betons eindringen, die ihn zerstören könnten, so kann dies entweder dadurch geschehen, daß, Betonmörtel, also ein Gemisch von Zement, Zuschlagstoffen und Wasser mittels der bekannten Rüttelmaschinen in den Riß. eingerüttelt wird, oder .es wird das sog. Einschlemmverfahren verwendet, d. h. es werden in den Riß Zement und Zuschlagstoffe trocken eingebracht und Wasser bzw. Zementmilch nachgefüllt. Diese beiden bekannten Verfahren lassen sich aber nur dann durchführen, wenn die Risse nicht zu fein, d. h. stärker als etwa 2 MM, sind. Sind die Risse weniger als 2 mm breit, so läßt sich der Beton nicht mehr einrütteln, weil er schon am. Rande des Risses hängenbleibt. Auch das Einschlemmverfahren versagt, weil die Zuschlagstoffe sich ebenfalls an den rauben Flächen der beiderseitigen R ssewände stauen und den von oben nachdringenden Massen den Weg nach unten versperren.Procedure for filling cracks in concrete ceilings and facing concrete If Cracks visible on the surface in concrete layers are to be filled the ugly: looking cracks not visible or to prevent * :, that liquids penetrate into the structure of the concrete, which could destroy it, so this can be done either by the fact that, concrete mortar, so a mixture of Cement, aggregates and water using the well-known vibrating machines in the Crack. is shaken in, or. the so-called entrapment method is used, i. H. cement and aggregates are brought into the crack dry and water or cement milk refilled. However, these two known methods can be used Carry out only if the cracks are not too fine, i.e. H. stronger than about 2 MM, are. If the cracks are less than 2 mm wide, the concrete can no longer be vibrated, because it gets stuck on the edge of the crack. The entrapment process also fails, because the aggregates are also on the rough surfaces of the mutual Damming back walls and blocking the way down for the masses penetrating from above.

Die vorliegende Erfindung ermöglicht es, auch feine, ja allerfeinste Risse vollkommen dicht auszufüllen. Sie ist dadurch gekennzeichnet, daß in den Riß zunächst eihe trockene Mischung aus Feinsand und Zement mittels eines schmalspurigen Rüttelgerätes eingebracht und erst dann das nötige Bindewasser zugesetzt wird. Die auf den Riß, aufgebrachte trockene Mischung aus Feinsand und Zement gleitet beim. Rütteln - des auf Schlittenkufen oder Rädern laufenden schmalspurigen Rüttelgeräts mit hoher Schwingungszahl, das am Riß entlanggeführt wird, in den Riß hinein und wird bei jeder etwaigen Stauung an den Rißwandungen sofort wieder frei gerüttelt, so daß die Mischung bis auf den Grund,des Risses gelangt. Nachdem auf diese. Weise der Riß zugefüllt ist, wird so viel Wasser zugefügt, wie die aufgefüllte Mischung zum Abbinden benötigt. Das Wasser dringt in die Hohlräume der Mischung eiri und bildet einen Betonmörtel, der in kurzer Zeit abbindet. Nach dem Abbinden des Mörtels werden die Rißwandungen durch einen Luftstrom ausgetrocknet. An Stelle des Aufschüttens eines Walles über dem Riß kann die Trockenmischung auch aus einem am Rüttelgerät angebrachten Behälter ständig zugeführt werden.The present invention makes it possible to produce even the finest, even the finest To fill cracks completely tight. It is characterized in that in the crack First, a dry mixture of fine sand and cement using a narrow-gauge Shaking device is introduced and only then is the necessary binding water added. the on the crack, applied dry mixture of fine sand and cement slides when. Vibrating - the narrow-gauge vibrating device running on sled runners or wheels with a high number of vibrations, which is guided along the crack, into the crack and is immediately shaken free again in the event of any congestion on the crack walls, so that the mixture gets to the bottom of the crack. After on this. way the crack is filled, as much water is added as the filled mixture needed for setting. The water penetrates into the cavities of the mixture eiri and forms a concrete mortar that sets in a short time. After setting of the mortar, the crack walls are dried out by a stream of air. Instead of of building a wall over the crack, the dry mix can also consist of a containers attached to the vibrator are constantly fed.
