Description

Die Erfindung betrifft einen Schlagknebel für eine Baugerüststütze, gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a striking gag for a scaffold support, according to the preamble of claim 1.

Ein derartiger Schlaghebel ist aus der GB-A-746083 bekannt.Such a striking lever is known from GB-A-746083.

Derartige Schlagknebel dienen dazu, eine unter Last stehende Baugerüststütze schnell abzusenken, wenn die Betonschalung, die durch diese Stütze gehalten wird, entfernt werden soll. Die Einstellmutter weist dazu radial vorspringende Flansche auf, so daß der erforderliche Hammerschlag angebracht werden kann. Dabei werden insbesondere auf die Einstellmutter große Kräfte übertragen, die langfristig zu einer Deformation oder auch Zerstörung der Einstellmutter führen. Der Griffbügel dient vorwiegend zum Verstellen der Einstellmutter bei geringer Stützenbelastung, also zum Einrichten der zum weiteren Lösen. Dazu wird er aus seiner im Ruhezustand parallel zur Stützenlängsachse befindlichen Lage verschwenkt und bildet somit einen die Bedienung erleichtenden Hebel.Knock gags of this type are used to quickly lower a scaffold support that is under load when the concrete formwork that is held by this support is to be removed. For this purpose, the adjusting nut has radially projecting flanges, so that the required hammer blow can be attached. Large forces are transmitted in particular to the adjusting nut, which in the long term lead to deformation or even destruction of the adjusting nut. The handle bar is mainly used to adjust the adjusting nut at low Support load, i.e. to set up for further loosening. For this purpose, it is swiveled out of its position parallel to the longitudinal axis of the support in the idle state and thus forms a lever that simplifies operation.

Der Erfindung liegt die Aufgabe zugrunde, einen einfachen und effektiven Schlaghebel zu schaffen, der preiswert herstellbar und einfach zu bedienen ist und der die bei einer Längsverstellung einer Baugerüststütze aufzubringenden Kräfte unbeschadet aufnehmen kann.The invention has for its object to provide a simple and effective impact lever that is inexpensive to manufacture and easy to use and that can absorb the forces to be applied in a longitudinal adjustment of a scaffold support without damage.

Diese Aufgabe wird durch einen erfindungsgemäßen Schlagknebel mit den Merkmalen des Anspruchs 1 gelöst. Vorteilhafte Ausgestaltungen sind Gegenstand der Unteransprüche.This object is achieved by a striking gag according to the invention with the features of claim 1. Advantageous refinements are the subject of the dependent claims.

Beim erfindungsgemäßen Schlagknebel ist der Griffbügel in einer horizontalen Lage senkrecht zur Stützenlängsachse fixierbar. Damit kann der zum Lösen der Mutter erforderliche Schlag auf den Griffbügel präzise unter einem genau definierten Winkel angebracht werden, so daß durch die im Vergleich zu herkömmmlichen Schlagknebeln günstigere Momentaufbringung die Deformationsarbeit an der Einstellmutter verringert wird.In the striking gag according to the invention, the handle bar can be fixed in a horizontal position perpendicular to the longitudinal axis of the support. Thus, the blow required to loosen the nut on the handle can be applied precisely at a precisely defined angle, so that the deformation work on the adjusting nut is reduced by the more favorable torque application compared to conventional knobs.

Bei einer bevorzugten Ausführungsform der Erfindung weist die Einstellmutter wenigstens einen radial vorspringenden Flansch mit einer im wesentlichen kreisförmigen Öffnung auf, wobei in der Öffnung wenigstens eine laterale Ausnehmung vorgesehen ist, in die der durch die Öffnung geführte Griffbügel einrastbar ist. Die laterale Ausnehmung bzw. die lateralen Ausnehmungen definieren eine stabile Lage des Griffbügels senkrecht zur Stützenlängsachse.In a preferred embodiment of the invention, the adjusting nut has at least one radially projecting flange with an essentially circular opening, at least one lateral recess being provided in the opening, into which the handle bar guided through the opening can be latched. The lateral recess or the lateral recesses define a stable position of the handle bar perpendicular to the longitudinal axis of the support.

Um die Einrastbarkeit des Griffbügels in die Öffnung zu gewährleisten, ist es vorteilhaft, wenn der Griffbügel ein in die Öffnung des Flansches einlegbares Zwischenstück aufweist, dessen Querschnitt in axialer Richtung kontinuierlich von einem elliptischen Querschnitt in einen kreisförmigen Querschnitt übergeht, wobei der Radius des kreisförmigen Querschnittes kleiner als die erste Halbachse und größer als die zweite Halbachse des elliptischen Querschnitts ist.In order to ensure that the handlebar can be snapped into the opening, it is advantageous if the handlebar has an intermediate piece which can be inserted into the opening of the flange, the cross section of which continuously changes in the axial direction from an elliptical cross section to a circular cross section, the radius of the circular cross section is smaller than the first semiaxis and larger than the second semiaxis of the elliptical cross section.

Weiter vorteilhaft weist der Griffbügel einen Hebel auf, wobei die Längsachse des Hebels im wesentlichen senkrecht zur Achse des Zwischenstückes liegt.The handle bracket further advantageously has a lever, the longitudinal axis of the lever being essentially perpendicular to the axis of the intermediate piece.

Der Hebel des Griffbügels kann sich über ein rechtwinklig gekrümmtes Anschlußstück an das Zwischenstück anschließen.The lever of the handle can connect to the adapter via a right-angled connector.

Das Herausgleiten des Griffbügels aus der Öffnung der Einstellmutter wird verhindert, wenn dem Zwischenstück ein Führungsabschnitt vorgelagert ist. Besonders vorteilhaft dabei ist, wenn der Führungsabschnitt mit einem Kragen versehen ist. Damit ist der Griffbügel unverlierbar an der Einstellmutter angebracht.The handlebar is prevented from sliding out of the opening of the adjusting nut if the intermediate piece is preceded by a guide section. It is particularly advantageous if the guide section is provided with a collar. The handle is therefore captively attached to the adjusting nut.

Nach einer weiteren Ausführungsform der Erfindung ist an der Einstellmutter ein zweigeteilter Flansch vorgesehen, dessen Flanschabschnitte je ein Langloch aufweisen. Dazu sind am Griffbügel zwei Achsstifte angebracht, die in je eines der Langlöcher eingreifen, wobei das Kopfstück des Griffbügels in eine zwischen den Flanschabschnitten in der Einstellmutter ausgebildete Ausnehmung einrastbar ist.According to a further embodiment of the invention, a two-part flange is provided on the adjusting nut, the flange sections of which each have an elongated hole. For this purpose, two axle pins are attached to the handle bracket, each of which engages in one of the elongated holes, the head piece of the handle bracket being able to be latched into a recess formed between the flange sections in the adjusting nut.

Für alle Ausführungsformen ist es vorteilhaft, den Hebel des Griffbügels flach auszubilden. Damit wird die Belastbarkeit in Beanspruchungsrichtung vergrößert.For all embodiments, it is advantageous to design the lever of the handle bar flat. This increases the resilience in the direction of stress.

Die Schlagunempfindlichkeit der Einstellmutter wird erhöht, wenn für sie ein steilgängiges oder mehrgängiges Gewinde verwendet wird.The impact resistance of the adjusting nut is increased if a steep or multi-start thread is used for it.

Die Vorteile des Schlagknebels gemäß der vorliegenden Erfindung erfordern keinen zusätzlichen Fertigungsaufwand oder Materialeinsatz gegenüber den bekannten Lösungen.The advantages of the toggle according to the present invention do not require any additional manufacturing outlay or use of materials compared to the known solutions.

Im folgenden soll die Erfindung lediglich beispielhaft anhand der beiliegenden Zeichnungen näher erläutert werden. Es zeigt:

In the following, the invention will be explained in more detail by way of example only with reference to the accompanying drawings. It shows:
  • 1 is a plan view of a percussion gag according to the present invention,
  • 2 shows a detailed illustration of the handle,

Der in Fig. 1 dargestellte Schlagknebel besteht aus einer Einstellmutter 2, die mit einem steilgängigen oder mehrgängigen Innengewinde 23 versehen ist und drei Flansche 3, 21, 22 aufweist, welche in winkelmäßig gleichen Abständen an ihrem Außenumfang angeordnet sind. Einer der Flansche 3 ist mit einer Öffnung 30 versehen, durch die ein Griffbügel 1 geführt ist. In der in Fig. 1 dargestellten Stellung ist der Griffbügel 1 in seiner horizontalen Lage fixiert, das heißt also bei Anbringen des Schlagknebels an einer Baugerüststütze in einer Lage senkrecht zur Stützenlängsachse. Dabei liegt der sich an ein Zwischenstück 12 anschließende Bereich eines gekrümmten Anschlußstückes 11 in der Öffnung 30. Das Einführen des Griffbügels 1 in die Öffnung 30 wird durch einen dem Zwischenstück 12 vorgelagerten Führungsabschnitt 13 erleichtert. An das gekrümmte Anschlußstück 11 schließt sich ein Hebel 10 an, der von der Einstellmutter 2 wegweist.1 consists of an adjusting nut 2, which is provided with a steep or multi-start internal thread 23 and has three flanges 3, 21, 22, which are arranged at equal angular intervals on their outer circumference. One of the flanges 3 is provided with an opening 30 through which a handle 1 is guided. In the position shown in FIG. 1, the handle bar 1 is fixed in its horizontal position, that is to say when the striker is attached to a scaffold support in a position perpendicular to the longitudinal axis of the support. The region of a curved connecting piece 11 adjoining an intermediate piece 12 lies in the opening 30. The introduction of the handle 1 into the opening 30 is facilitated by a guide section 13 upstream of the intermediate piece 12. A lever 10, which points away from the adjusting nut 2, adjoins the curved connecting piece 11.

In Fig. 2 ist der Griffbügel 1 detailliert dargestellt. Teilabbildung (a) zeigt eine Seitenansicht (in bezug auf die Ruhestellung des Griffbügels parallel zur Stützenlängsachse) bzw. eine Draufsicht (in bezug auf die horizontale Lage senkrecht zur Stützenlängsachse) des Griffbügels 1. Ein rechtwinklig gekrümmtes Anschlußstück 11 verbindet einen Hebel 10 und ein Zwischenstück 12 bei einem Führungsabschnitt 13. An den dem gekrümmten Anschlußstück 11 zugewandten Ende hat das Zwischenstück 12 einen elliptischen Querschnitt, an dem dem Führungsabschnitt 13 zugewandten Ende einen kreisförmigen. Das Zwischenstück 12 ist so ausgebildet, daß der Übergang zwischen diesen verschiedenen Querschnitten kontinuierlich ist. Das gekrümmte Anschlußstück 11 und auch der Hebel 10 weisen denselben elliptischen Querschnitt auf wie das entsprechende Ende des Zwischenstückes 12. In dieser Darstellung des Griffbügels 1 verjüngt sich das Zwischenstück in Richtung auf den Führungsabschnitt 13 hin. Teilabbildung (b) zeigt eine Ansicht des Griffbügels von unten. Wegen des elliptischen Querschnittes des Hebels 10 und des Anschlußstückes 11 erweitert sich das Zwischenstück 12 in dieser Darstellung auf den Führungsabschnitt 13 hin. Durch die besondere Wahl der Querschnittsflächen ändern sich der wirksame Querschnitt des Zwischenstückes und seine Außenkontur vom Anschlußstück 11 in Richtung seiner Längsachse auf den Führungsabschnitt 13 hin. Durch diese besondere Ausbildung des Zwischenstückes wird durch den Übergang von einer Querschnittsform zu einer anderen ein definierter Übergang zwischen zwei verschiedenen stabilen Lagen des Griffbügels möglich. Da auch der Hebel 10 einen elliptischen Querschnitt aufweist, also flach ausgebildet ist, kann er große Kräfte, wie sie bei dem erforderlichen Hammerschlag auftreten, aufnehmen, ohne daß dabei Deformationen auftreten. Die Beanspruchungsrichtung liegt dabei in Richtung der großen Halbachse der Ellipse. Teilabbildung (c) zeigt eine Draufsicht auf das Zwischenstück 12 von der Linie A-A aus Teilabbildung (a) aus gesehen. Der Radius 131 des kreisförmigen Querschnittes 130 ist dabei größer als die Länge der kleinen Halbachse 112 des elliptischen Querschnittes 110, jedoch kleiner als die Länge der großen Halbachse 111 des elliptischen Querschnittes.2, the handle 1 is shown in detail. Partial illustration (a) shows a side view (with respect to the rest position of the handlebar parallel to the longitudinal axis of the support) or a top view (with respect to the horizontal position perpendicular to the longitudinal axis of the support) of the handlebar 1. A right-angled connector 11 connects a lever 10 and an intermediate piece 12 at a guide section 13. At the end facing the curved connecting piece 11, the intermediate piece 12 has an elliptical cross section, at which the guide section 13 facing end a circular. The intermediate piece 12 is designed so that the transition between these different cross sections is continuous. The curved connecting piece 11 and also the lever 10 have the same elliptical cross section as the corresponding end of the intermediate piece 12. In this illustration of the handle 1, the intermediate piece tapers in the direction of the guide section 13. Partial illustration (b) shows a view of the handle from below. Because of the elliptical cross section of the lever 10 and the connecting piece 11, the intermediate piece 12 extends in this illustration to the guide section 13. Due to the special selection of the cross-sectional areas, the effective cross-section of the intermediate piece and its outer contour change from the connecting piece 11 in the direction of its longitudinal axis towards the guide section 13. This special design of the intermediate piece makes a defined transition between two different stable positions of the handlebar possible by the transition from one cross-sectional shape to another. Since the lever 10 also has an elliptical cross section, that is to say is of flat design, it can absorb large forces, such as those which occur with the required hammer blow, without any deformation occurring. The direction of stress lies in the direction of the large semi-axis of the ellipse. Partial illustration (c) shows a top view of the intermediate piece 12 as seen from the line AA from partial illustration (a). The radius 131 of the circular cross section 130 is larger than the length of the small semiaxis 112 of the elliptical cross section 110, but smaller than the length of the large semiaxis 111 of the elliptical cross section.

Fig. 3 zeigt eine bevorzugte Ausführungsform des Griffbügels 1, bei der dem Führungsabschnitt 13 ein Kragen 14 vorgelagert ist, der den Griffbügel unverlierbar in der Öffnung der Einstellschraube hält, wenn er einmal angebracht ist. Ansonsten entspricht diese Ausführungsform des Griffbügels derjenigen der Fig. 2.Fig. 3 shows a preferred embodiment of the handle 1, in which a collar 14 is in front of the guide portion 13, which holds the handle captively in the opening of the adjusting screw, once it is attached. Otherwise, this embodiment of the handle bracket corresponds to that of FIG. 2.

Fig. 4 zeigt eine Schnittansicht der Einstellmutter, wie sie im Zusammenhang mit der Erfindung verwendet wird. In einem der Flansche 3 ist eine Öffnung 30 vorgesehen, die im wesentlichen kreisförmig ist und in lateraler Richtung mit zwei Ausnehmungen 31, 32 versehen ist. Die Abmessungen dieser Öffnung 30 sind so gewählt, daß die Ausnehmungen 31, 32 eine Längserstreckung definieren, die derjenigen der großen Halbachse des elliptischen Querschnittes des Führungsstückes 12 bzw. des Anschlußstückes 11 entsprechen. Wenn der in die Öffnung 30 eingesetzte Griffbügel in die horizontale Richtung verschwenkt wird, gleitet das Zwischenstück 12 durch die Öffnung, bis das Anschlußstück 11 abgestützt in die Ausnehmungen 31, 32 zu liegen kommt. Auf diese Weise wird der Griffbügel 1 in der Einstellmutter 2 fixiert.Fig. 4 shows a sectional view of the adjusting nut as used in connection with the invention. An opening 30 is provided in one of the flanges 3, which is essentially circular and is provided with two recesses 31, 32 in the lateral direction. The dimensions of this opening 30 are chosen so that the recesses 31, 32 define a longitudinal extent which corresponds to that of the large semiaxis of the elliptical cross section of the guide piece 12 or of the connecting piece 11. When the handle inserted into the opening 30 is pivoted in the horizontal direction, the intermediate piece 12 slides through the opening until the connecting piece 11 comes to rest supported in the recesses 31, 32. In this way, the handle 1 is fixed in the adjusting nut 2.

Fig. 5 zeigt eine weitere Ausbildung der Öffnung 30, bei der einander gegenüberliegende Kerben 37, 38 vorgesehen sind, die die stabile horizontale Lage des Griffbügels definieren sollen. Die Ausgestaltung der Öffnung 30 nach Fig. 5a ist zweckmäßig, wenn als Material für den Griffbügel Flachstahl verwendet wird. Die Ausnehmungen 37', 38' sind entsprechend dem Querschnitt des Flachstahles ausgestaltet, liegen einander also wieder gegenüber und definieren zusammen mit dem zwischen ihnen liegenden Bereich der Öffnung 30 einen rechteckigen, wirksamen Querschnitt. In Fig. 6 ist bei einer dritten Ausgestaltung der Öffnung 30 nur eine Ausnehmung 39 vorgesehen, die ebenfalls den Griffbügel halten soll. Die Querschnittsgestaltung des Zwischenstückes 12 bzw. des Anschlußstückes 11 des Griffbügels muß jeweils entsprechend gewählt werden, so daß gewährleistet ist, daß das Anschlußstück 11 wenigstens teilweise paßgenau in die Ausnehmungen zu liegen kommt, wenn der Griffbügel die gewünschte horizontale Lage erreicht hat.Fig. 5 shows a further embodiment of the opening 30, in which opposing notches 37, 38 are provided which are intended to define the stable horizontal position of the handle. 5a is expedient if flat steel is used as the material for the handle bar. The recesses 37 ', 38' are designed in accordance with the cross section of the flat steel, that is to say they face each other again and, together with the region of the opening 30 between them, define a rectangular, effective cross section. 6 is in a third embodiment only a recess 39 is provided in the opening 30, which should also hold the handle. The cross-sectional design of the intermediate piece 12 or the connecting piece 11 of the handle must be selected accordingly, so that it is ensured that the connector 11 comes to lie at least partially in the recesses when the handle has reached the desired horizontal position.
