Abstract

Parallel running rails (2), are supported on tripods which are adjustable for height, on the appliance for skimming off or smoothing concrete work. The adjusting threaded spindle (4) can be set for length in a running socket (5), via a manually operated adjusting nut (6). It pref. has a bottom end elastic ring (7), permitting it to be drawn out of the socket with him. effort. The socket may be closed at the bottom by a cup-shaped extension sleeve (8). This provides direct, continuous unimpeded height setting, and movable parts are largely protected from dirt.

Description

Höhenverstelleinrichtung für Abziehbohle Height adjustment device for screed

Die Erfindung betrifft eine Höhenverstelleinrichtung für Abziehbohle zum Einebnen und Glätten von Betonschüttungen oder dgl. mit parallel angeordneten Laufschienen die sich auf Dreibeinständern abstützen, welche höhenverstellbar ausgeführt sind.The invention relates to a height adjustment device for a screed for leveling and smoothing concrete fillings or the like. With arranged in parallel Running rails that are supported on tripod stands, which are height-adjustable are.

Bei der Herstellung von ebenen Betonflächen werden Abziehbohlen verwendet, die quer zu den auf Dreibeinständern ruhenden Laufschienen aufgelegt werden und parallel zu ihnen gezogen werden, wodurch die frische Betonmasse eingeebnet und glattgezogen wird. Derartige Abziehbohlen können noch zusätzlich mit Rollen ausgerüstet selen um ein leichteres abziehen zu erreichen.Screed piles are used in the production of flat concrete surfaces, which are placed across the running rails resting on tripod stands and be pulled parallel to them, thereby leveling the fresh concrete mass and is smoothed. Such screeds can also be equipped with rollers selenium to make it easier to peel off.

Es sind Rüttelbohlen bekannt, deren Laufschienen auf Dreibeinständern aufgesetzt sind, welche durch Verdrehen des gesamten Ständers in der Höhe verstellt werden. Das wirkt sich in der Praxis sehr naohteilig aus, weil eine Verdrehung des Dreibeinständers durch Beton und Baustahlmatten bzw. Armierungsstäbe kaum möglich ist.Vibrating screeds are known whose rails are on tripod stands are attached, which can be adjusted in height by rotating the entire stand will. This has a very negative effect in practice, because a twisting of the Tripod stand through concrete and welded wire mesh or reinforcing bars is hardly possible is.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Höhenverstelleinrichtung für Abziehbohlen zu schaffen, welche eine direkte, stufenlose und ohne Behinderung durchzuführende Höhenverstellung erlaubt. Außerdem muß dem starken Schmutzanfall auf der Baustelle dadurch Rechnung getragen werden, daß die bewegten Teile weitgehendst gekapselt angeordnet sind um eine hohe Betriebssicherheit zu erreichen.The invention is therefore based on the object of a height adjustment device for screeds, which are direct, stepless and without hindrance height adjustment to be carried out allowed. In addition, the heavy dirt accumulation must be taken into account on the construction site that the moving parts largely are arranged encapsulated in order to achieve a high level of operational reliability.

Die gestellte Aufgabe wird erfindungsgemäß dadurch gelöst, daß eine Gewindespindel (4) in einer Laufbüchse (5) über eine handbetätigte Versteilmutter (6) in der Höhe verstellt werden kann und daß die Gewindespindel (4) an dem unteren Ende einen elastischen Ring (7) aufweist, welcher ein Herausziehen der Spindel (4) aus der Laufbüchse (5) nur mit erheblichem Kraftaufwand gestattet und daß'die Laufbüchse (5) durch eine topfartige Verlängerung (8) nach unten verschlossen ist.The object is achieved according to the invention in that a Threaded spindle (4) in a liner (5) via a hand-operated adjusting nut (6) can be adjusted in height and that the threaded spindle (4) on the lower End has an elastic ring (7), which allows the spindle (4) to be pulled out from the liner (5) allowed only with considerable effort and that'die liner (5) is closed at the bottom by a pot-like extension (8).

Nachfolgend wird ein Ausführungsbeispiel einer erfindungsgemäß ausgebildeten Höhenverstellung anhand der beiliegenden Zeichnungen näher erläutert. Figur 1 zeigt eine Gesambdarstellung der Abziehbohle mit Laufschiene und Höhenverstellung im praktischen Einsatz. Figur 2 zeigt eine Schnittdarstellung des Dreibeinständers mit Höhenverstellung.The following is an embodiment of one designed according to the invention Height adjustment explained in more detail with reference to the accompanying drawings. Figure 1 shows an overall representation of the screed with running rail and height adjustment in a practical way Mission. Figure 2 shows a sectional view of the tripod stand with height adjustment.

Figur 1 zeigt die Abziehbohle (1), welche zum Glätten der Betonfüllung (9) über die Laufschienen (2) gezogen wird. Die Laufschienen (2) sind in den Haltebügeln (10) über die Flügelschraube (11) eingespannt und stützen sich somit auf den Dreibeinständern (3) ab. Die Füsse (12) der Dreibeinständer (3) sind auf dem Deckenrundament aufgesetzt. Figur 2 zeigt in der Schnittdarstellung den Dreibeinständer t)) mit HöhenverstelLung, Durch Verdrehen der Verstellmutter (6) können die Laufschienen ohne Behinderung niveliert und ausgerichtet werden. Die Laufbüchse (5) dient nur zur Spindellagerung und hat selbst kein Gewinde. Die topfartige Verlängerung (8) mit dem Abschlußdeckel (13) schützen die Spindel vor Verschmutzung.Figure 1 shows the screed (1), which is used to smooth the concrete filling (9) is pulled over the rails (2). The running rails (2) are in the retaining brackets (10) clamped in via the wing screw (11) and are thus supported on the tripod stands (3) off. The feet (12) of the tripod stand (3) are placed on the base of the ceiling. Figure 2 shows a sectional view of the tripod stand t)) with height adjustment, By turning the adjusting nut (6), the rails can be moved without hindrance be leveled and aligned. The liner (5) is only used for spindle bearings and has no thread itself. The pot-like extension (8) with the cover (13) protect the spindle from contamination.

Damit beim Transport der Dreibeinständer (3) die Gewindespindel (4) nicht aus der Laufbüchse (5) herausgezogen werden kann, trägt die Gewindespindel (4) am unteren Ende einen elastischen Ring (7), welcher in seinen Abmessungen so gehalten ist, daß er bei der Montage bzwO Demontage nur mit größerem Kraftaufwand durch die Bohrung der Laufbüchse (5) gepresst werden kann.So that when the tripod stand (3) is transported, the threaded spindle (4) cannot be pulled out of the liner (5), the threaded spindle carries (4) at the lower end an elastic ring (7), which in its dimensions so is held that he only with greater effort during assembly or disassembly can be pressed through the bore of the liner (5).
