Description

Die Erfindung betrifft eine Grabenverbauvorrichtung, bestehend aus mittels Spreizen auf parallelen Abstand gehaltenen Verbaustützen und in diesen mittels Führungsrollen geführten Verbauplatten.The invention relates to a trench shoring device, consisting of shoring supports kept at a parallel distance by means of spreading and shoring plates guided therein by means of guide rollers.

Aus der DE-23 23 321 B2 ist eine solche Verbauvorrichtung bekannt. Hierbei sind an den Stirnseiten der Verbauplatten mit Abstand übereinander angeordnete Führungsköpfe mit Führungsrollen vorgesehen, von denen einige auf Achsen senkrecht zur Verbauplattenebene und andere auf Achsen gelagert sind, die in einer Ebene zwischen den Seitenflächen der Verbauplatte und senkrecht zur Führungsstütze stehen und soweit versetzt angeordnet sind, daß sie jeweils nur auf dem zum Grabeninnern weisenden Schenkel des Profiles der Führungsstütze laufen.Such a shoring device is known from DE-23 23 321 B2. Here, on the end faces of the sheeting panels, spaced-apart guide heads with guide rollers are provided, some of which are mounted on axes perpendicular to the sheeting panel plane and others on axles which are in a plane between the side surfaces of the sheeting panel and perpendicular to the guide support and are arranged so far offset that they run only on the leg of the profile of the guide support pointing towards the inside of the trench.

Mit dieser Konstruktion sollte erreicht werden, daß die Verbauplatten ohne große Reibung in den Führungsstützen bewegt werden konnten. Es zeigte sich jedoch, daß diese Konstruktion im rauhen Baubetrieb nicht stark genug war und eine Führung mit quer zur Verbauplattenebene ausgebildeten starren Flanschen weiterhin erforderlich war. Dies war umso mehr geboten, als die Führungsrollen notwendigerweise mit sehr großem Spiel laufen mußten, und daher die Verbindungsstelle von Führungsstütze und Verbauplatte instabil war. Dies galt besonders für kompakte Böden, die nicht ohne weiteres gegen die Verbauvorrichtung drückten.This construction was intended to ensure that the shoring plates could be moved in the guide supports without great friction. However, it was found that this construction was not strong enough in rough construction and that a guide with rigid flanges formed transversely to the shoring plane level was still required. This was all the more necessary since the guide rollers necessarily had to run with a great deal of play, and therefore the connection point between the guide support and the shoring plate was unstable. This was especially true for compact floors that did not easily press against the shoring device.

Aus der GB- 2 172 029 A ist eine Grabenverbauvorrichtung bekannt, bei der an den Stirnwänden der Verbauplatten ebenfalls Führungsrollen vorgesehen sind. Diese laufen jedoch ausschließlich auf Achsen senkrecht zur Verbauplattenebene, während die Verbauplatten gegen den Druck der Grabenwand formschlüssig mittels starrer Elemente in den Führungsstützen geführt sind.From GB-2 172 029 A a trench shoring device is known in which guide rollers are also provided on the end walls of the shoring panels. However, these run exclusively on axes perpendicular to the facing plate level, while the facing plates are guided in a form-fitting manner against the pressure of the trench wall by means of rigid elements in the guide supports.

Der Erfindung liegt die Aufgabe zugrunde, eine Verbauvorrichtung zu schaffen, bei der die in bekannter Weise mittels Führungsrollen reibungsarme Rollenanordnung gegenüber dem Stand der Technik so verbessert sein soll, daß eine stabile Verbindung von Verbauplatte und Führungsstütze ausschließlich mit Führungsrollen und ihren Führungselementen erzielt werden soll.The invention has for its object to provide a shoring device in which the low-friction roller arrangement in a known manner by means of guide rollers is to be improved over the prior art in such a way that a stable connection of the shoring plate and guide support is to be achieved only with guide rollers and their guide elements.

Die Lösung der gestellten Aufgabe besteht erfindungsgemäß in den kennzeichnenden Merkmalen des Anspruches 1.According to the invention, this object is achieved in the characterizing features of claim 1.

Eine alternative Lösung stellt die kinematische Umkehrung entsprechend den kennzeichnenden Merkmalen des Anspruches 2 dar.An alternative solution is the kinematic reversal in accordance with the characterizing features of claim 2.

In den Unteransprüchen sind vorteilhafte Ausgestaltungen der beiden Lösungsvorschläge gegeben.Advantageous refinements of the two proposed solutions are given in the subclaims.

Die Fig.1 bis 3 zeigen eine Verbauplatte 1 einer Grabenverbauvorrichtung. Eine solche Grabenverbauvorrichtung besteht im allgemeinen aus zwei parallelen Reihen von Verbauplatten und diese haltenden Führungsstützen sowie zwischen den Verbauplatten oder Führungsstützen eingesetzten Spreizen, die die beiden Reihen auf Abstand halten und gegen die anstehenden Grabenwände abstützen.1 to 3 show a shoring plate 1 of a trench shoring device. Such a trench shoring device generally consists of two parallel rows of shoring plates and guide supports holding them and spreaders inserted between the shoring plates or guide supports which keep the two rows at a distance and support them against the trench walls.

Eine Verbauplatte 1 besteht im allgemeinen aus einem Hohlkörper, der aus Blechplatten und ggf. Profilstahlteilen gebildet ist. Sie istim einzelnen nicht Gegenstand der Erfindung.A shoring plate 1 generally consists of a hollow body which is formed from sheet metal plates and, if appropriate, section steel parts. In particular, it is not the subject of the invention.

An ihrer schmalen Stirnseite 2 weist die Verbauplatte eine Anzahl übereinander angeordneter vorstehender Zapfen 3 auf, auf denen Führungsrollen 4 und 5 laufen.On its narrow end face 2, the shoring plate has a number of projecting pins 3 arranged one above the other, on which guide rollers 4 and 5 run.

Wie Fig.3 zeigt, sind übereinander angeordnete Zapfen 3 jeweils um ein geringes Maß zueinander soweit quer versetzt angeordnet, daß zwei Verbindungslinien 6 und 7 jeweils durch die Führungsrollen 4 bzw. 5 gehen, die ihrerseits abwechselnd übereinander sitzen.As FIG. 3 shows, pins 3 arranged one above the other are each offset by a small amount to such an extent that two connecting lines 6 and 7 each pass through the guide rollers 4 and 5, which in turn sit alternately one above the other.

Fig. 4 zeigt einen vergrößerten Querschnitt durch eine Verbindungsanordnung zwischen einer Führungsstütze 8 und einem Teil der Verbauplatte 1 nach den Fig.1 bis 3.4 shows an enlarged cross section through a connection arrangement between a guide support 8 and part of the shoring plate 1 according to FIGS. 1 to 3.

Die Führungsstütze 8 besteht aus einem Stahlprofil, bei dem zwei mit ihren Stegen gegeneinander gerichtete U-Profile 9 durch ein hierzu senkrecht stehendes U-Profil 11 auf Abstand gehalten sind, dessen U-Schenkel jeweils die Stege der U-Profile 9 bilden und dessen Steg eine Verlängerung der der Grabenwand zugekehrten U-Schenkel 10 der U-Profile 9 bilden.The guide support 8 consists of a steel profile, in which two U-profiles 9, which are directed towards one another with their webs, are kept at a distance by a U-profile 11 which is perpendicular thereto, the U-legs of which each form the webs of the U-profiles 9 and the web an extension of the U-legs 10 of the U-profiles 9 facing the trench wall.

Das U-Profil 11 dient zur Aufnahme einer nicht dargestellten Spreize, die sich an einer ebenfalls nicht dargestellten weiteren Führungstsütze quer zur Grabenlängsrichtung abstützt.The U-profile 11 serves to accommodate a strut, not shown, which is supported on a further guide support, also not shown, transversely to the longitudinal direction of the trench.

Die seitlichen U-Profile 9 haben auf den Innenseiten ihrer U-Schenkel 10 parallele Führungsleisten 12, die z.B. aus aufgeschweißten Rundprofilstäben bestehen können.The lateral U-profiles 9 have on the inner sides of their U-legs 10 parallel guide strips 12 which e.g. can consist of welded round profile bars.

Wie Fig.4 zeigt, sind die Führungsrollen 4 und 5 als Profilrollen ausgebildet und weisen eine im Querschnitt etwa halbkreisförmige Führungsnut 13 auf, die dem Profil der Führungsleisten 12 entspricht. Zweckmäßig sitzen auf jedem Zapfen 3 mindestens zwei Führungsrollen 4,5 und stehen abwechselnd mit den gegenüberstehenden Führungsleisten 12 in formschlüssigem Eingriff. Dabei laufen die Führungsrollen 4 auf den Führungsleisten 12 des einen und die Führungsrollen 5 auf den Führungsleisten 12 des anderen U-Schenkels 10 des U-Profiles 9. Zweckmäßig ist die aus den Zapfen 3 und den Führungsrollen 4 bzw.5 gebildete Anordnung in Richtung der Zapfenachse länger als in Querrichtung und in Querrichtung nicht größer als die Stärke der Verbauplatte 1. Auf diese Weise wird ein unerwünschtes und unberechenbare Kräfte bewirkendes Spiel zwischen Verbauplatte 1 und Führungsstützze 8 vermieden. Die durch die mehreren Führungsrollen bedingte relativ lange Anlagefläche bewirkt eine besondere Stabilität dieser Verbindung.As FIG. 4 shows, the guide rollers 4 and 5 are designed as profile rollers and have an approximately semicircular guide groove 13 in cross section, which corresponds to the profile of the guide strips 12. At least two guide rollers 4, 5 are expediently seated on each pin 3 and are in alternating positive engagement with the opposite guide strips 12. The guide rollers 4 run on the guide rails 12 of one and the guide rollers 5 on the guide rails 12 of the other U-leg 10 of the U-profile 9. The arrangement formed from the pins 3 and the guide rollers 4 and 5 is expedient in the direction of Pin axis longer than in the transverse direction and in the transverse direction not greater than the thickness of the shoring plate 1. In this way, an undesirable and unpredictable force-causing play between shoring plate 1 and guide support 8 is avoided. The relatively long contact surface caused by the several guide rollers brings about a special stability of this connection.

Statt profilierter Führungsrollen 4 und 5 können auch zylindrische Führungsrollen vorgesehen sein. In diesem Fall greifen die Führungsleisten in den Zwischenraum zwischen zwei hintereinander laufenden Führungsrollen 4 bzw. 5 ein, die ihrerseits unmittelbar auf dem zugeordneten U-Schenkel 10 laufen. (nicht dargestellt).Instead of profiled guide rollers 4 and 5, cylindrical guide rollers can also be provided. In this case, the guide strips engage in the intermediate space between two guide rollers 4 and 5 running one behind the other, which in turn run directly on the assigned U-leg 10. (not shown).

Fig.5 zeigt die kinematische Umkehrung der Verbindungsanordnung nach Fig.4.5 shows the kinematic reversal of the connection arrangement according to Fig. 4.

In diesem Falle haben die Verbauplatten 1 einen Führungskopf 14 in der Form eines U-Profiles, dessen Steg die Stirnseite 2 der Verbauplatte 1 bildet.In this case, the shoring plates 1 have a guide head 14 in the form of a U-profile, the web of which forms the end face 2 of the shoring plate 1.

Die U-Schenkel 22 dieses Führungskopfes 14 weisen auf ihren Innenseiten parallele Führungsleisten 15 auf. Die Führungsstütze 18 weist ein U-Profil 16 zur Aufnahme des nur schematisch dargestellten Stützschuhes 17 einer Spreize 19 auf.The U-legs 22 of this guide head 14 have parallel guide strips 15 on their inner sides. The guide support 18 has a U-profile 16 for receiving the support shoe 17 of a strut 19, which is only shown schematically.

Der Steg 20 dieses U-Profiles ist beiderseits über seine U-Schenkel 16 verlängert. Diese Verlängerung 21 bildet einen Schutzschild gegen eine Verschmutzung der auf den U-Schenkeln 16 sitzenden Bolzen 23 mit den darauf sitzenden Führungsrollen 24,25. Diese Führungsrollen 24,25 sind, wie im Falle der Fig.4 ebenfalls in zwei nebeneinander angeordneten parallelen Reihen so angeordnet, daß sie, wenn der Führungskopf 14 der zugehörigen Verbauplatte 1 formschlüssig mit den Führungsrollen 24,25 der Führungsstütze in Eingriff steht, abwechselnd am einen oder anderen U-Schenkel 22 des Führungskopfes 14 anliegen. Für die Längen- und Quererstreckung der Verbindungsanordnung aus Bolzen und Führungsrollen gilt hier das gleiche wie bei der voraus beschriebenen Ausführungsform der Fig.4.The web 20 of this U-profile is extended on both sides via its U-legs 16. This extension 21 forms a protective shield against contamination of the bolts 23 seated on the U-legs 16 with the guide rollers 24, 25 seated thereon. These guide rollers 24, 25 are, as in the case of FIG. 4, also arranged in two parallel rows arranged next to one another in such a way that when the guide head 14 of the associated lining plate 1 is in positive engagement with the guide rollers 24, 25 of the guide support, they alternate on one or another U-leg 22 of the guide head 14 abut. The same applies here as for the previously described embodiment of FIG. 4 for the longitudinal and transverse extension of the connection arrangement comprising bolts and guide rollers.

Wie beim vorgenannten Ausführungsbeispiel können die Führungsrollen profiliert oder zylindrisch ausgebildet sein.As in the aforementioned embodiment, the guide rollers can be profiled or cylindrical.
