Abstract

A panel (2) used to support the sides of a trench. It has a cutting profile (1) formed along its lower edge. A matching cap (5), which is V-shaped is attached to this cutting edge. There are several pipes (9) or stubs, attached to the underside of the cap, and projecting downwards. They project a considerable length, and can be at least one third of the length of the panel height. USE/ADVANTAGE - Trench or excavation support panel is self-supporting for short periods when props removed.

Description

Die Erfindung betrifft eine Vorrichtung zum Halten von vorzugsweise stützenlosen Grabenverbauplatten.The invention relates to a device for holding preferably pillarless trench sheeting.

Beim Einsetzen relativ langer Rohrleitungen in durch Grabenver­ bauplatten gesicherte Gräben kommt es immer wieder vor, daß die die einander gegenüberstehenden Grabenverbauplatten auf Abstand haltenden Steifen den Einbau der Rohrleitungen behindern. Ein zeitweiliges Entfernen der Steifen kann die Statik der Verbauvorrichtung beeinträchtigen.When installing relatively long pipes in through trench ver Trenches secured with building boards, it happens again and again that the the trench sheeting plates facing each other at a distance stiffening stiffeners prevent the installation of the pipes. A Temporary removal of the stiffeners can reduce the static Affect shoring device.

Auch kann es vorkommen, daß beim Einsetzen von Grabenverbau­ platten in lose Böden eine geringe Standfestigkeit besteht und besondere Maßnahmen erforderlich sind, um ein sicheres Einbrin­ gen der Grabenverbauplatten zu gewährleisten. Dies gilt insbesondere für stützenlose, sogenannte Schachtplatten, deren Ränder nicht in Gleitschienen geführt sind.It can also happen that when digging trenches in loose soils there is little stability and special measures are required to ensure a safe introduction to ensure the trench sheeting panels. this applies especially for pillarless, so-called manhole panels, the Edges are not guided in slide rails.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zu schaffen, die es gestattet, eine Grabenverbauplatte auch dann zuverlässig im Erdboden zu halten, wenn sie nicht in Gleit­ schienen geführt und gestützt ist und sie auch standfest zu halten, wenn die Steifen kurzfristig entfernt sind.The invention has for its object a device create that allows a trench sheeting panel even then to hold reliably in the ground when not in glide seemed to be guided and supported and also stable hold when the stiffeners are removed for a short time.

Die Lösung der gestellten Aufgabe besteht in den kennzeichnen­ den Merkmalen des Anspruches 1. The solution to the task is to label the features of claim 1.  

In der DE-PS 22 30 395 ist zwar bereits offenbart, an einer Grabenverbauplatte nach unten vorstehende Rohrspitzen vorzuse­ hen, doch dienten diese nicht einer Verbesserung der Standfe­ stigkeit sondern, da sie relativ kurz waren, dem Absaugen von Grundwasser oder dem Einbringen einer thixotropen Flüssigkeit, wie dies in der Druckschrift auch angegeben ist. Auch offenbart diese Patentschrift keine Schneide am unteren Ende der Verbauplatte.DE-PS 22 30 395 has already been disclosed on one Trench sheeting plate protruding downward pipe tips hen, but these were not used to improve the stand but, since they were relatively short, the suction of Groundwater or the introduction of a thixotropic liquid, as indicated in the publication. Also revealed this patent does not have a cutting edge at the lower end of the Sheeting plate.

Die erfindungsgemäße Vorrichtung bietet mit den Rohren oder Rammdielen einen ausgezeichneten Hebelarm um die Grabenverbau­ platte im Erdboden sicher zu halten und trägt dazu bei, im Falle sehr langer, in den Graben einzubringender Rohre einen besonderen baulichen Aufwand zu vermeiden.The device according to the invention offers with the tubes or Rammdielen an excellent lever arm around the trench shoring to hold the plate securely in the ground and helps in In the case of very long pipes to be inserted into the trench, one to avoid special structural effort.

In den Unteransprüchen sind vorteilhafte Weiterbildungen der Erfindung angegeben.Advantageous further developments of the Invention specified.

Nachstehend ist die Erfindung anhand der Zeichnung beispiels­ weise näher erläutert. Es zeigtThe invention based on the drawing is an example explained in more detail. It shows

Fig. 1 einen lotrechten Längsschnitt durch eine mit einer Schneide verbundene Vorrichtung nach der Erfindung und Fig. 1 is a vertical longitudinal section through a device connected to a cutting edge according to the invention and

Fig. 2 eine Seitenansicht zu Fig. 1. FIG. 2 shows a side view of FIG. 1.

Die Zeichnung zeigt eine Schneide 1 einer Grabenverbauplatte 2. Diese Schneide hat eine - im Betrieb dem Grabenrand zugewandte lotrechte Außenwand 3 und eine hierzu im Winkel β von etwa 15-30° stehende Innenwand 4. Sie ist mit der darüber befindli­ chen Grabenverbauplatte 2 in der Regel fest verbunden.The drawing shows a cutting edge 1 of a trench sheeting panel 2 . This cutting edge has a vertical outer wall 3 which faces the edge of the trench during operation and an inner wall 4 which is at an angle β of approximately 15-30 °. It is generally firmly connected to the trench sheeting plate 2 above.

Auf diese Schneide 1 ist lösbar eine Kappe 5 aufgesteckt, deren Querschnitt demjenigen der Schneide 1 angepaßt ist und aus V-förmig zueinander stehenden Blechen gebildet ist. Die auf der Außenwand 3 der Schneide 1 liegende Vorderwand 6 der Kappe 5 steht ebenfalls im Winkel β zur auf der Innenwand 4 der Schneide 1 liegenden Rückwand 7 der Kappe 5.A cap 5 is detachably fitted onto this cutting edge 1 , the cross section of which is adapted to that of the cutting edge 1 and is formed from sheets which are in a V-shape with respect to one another. The front wall 6 of the cap 5 lying on the outer wall 3 of the cutting edge 1 is also at an angle β to the rear wall 7 of the cap 5 lying on the inner wall 4 of the cutting edge 1 .

Entlang dein Scheitel 8 der Kappe 5 sind mit Abstand hierzu rechtwinklig relativ lange Rohre oder Rammdielen 9 angebracht, deren Länge mindestens etwa einem Drittel der Höhe der Grabenverbauplatte 2 gleichkommt. Diese Rohre oder Rammdielen haben angespitzte Enden 10.Along your apex 8 of the cap 5 , relatively long pipes or ramming boards 9 are attached at a distance from it, the length of which is equal to at least about a third of the height of the trench sheeting panel 2 . These pipes or ramming boards have tapered ends 10 .

Die Kappe 5 ist mittels Haltebolzen 11 an der Schneide 1 lösbar befestigt. Die Haltebolzen ragen durch geeignete Bohrungen 12, 13 in der Schneide 1 bzw. der Kappe 5.The cap 5 is detachably attached to the cutting edge 1 by means of retaining bolts 11 . The retaining bolts protrude through suitable bores 12 , 13 in the cutting edge 1 or the cap 5 .

Wird die mit dieser Vorrichtung versehene Grabenverbauplatte 2 in den Erdboden gedrückt, so erhält sie mit den angesetzten "Stelzen" eine bedeutende Standfestigkeit. Da der Querschnitt der Rohre oder Rammdielen relativ gering ist, genügen bereits kleinere Eindrückvorrichtungen (Bagger oder dgl.) um die Grabenverbauplatte an Ort und Stelle einzusetzen, bevor die Grabenverbauplatte endgültig fixiert wird.If the trench sheeting plate 2 provided with this device is pressed into the ground, it receives a significant stability with the attached "stilts". Since the cross-section of the pipes or ramming planks is relatively small, small push-in devices (excavators or the like) are sufficient to insert the trench sheeting panel in place before the trench sheeting panel is finally fixed.

Gleiches gilt auch für den Rückbau. Die Grabenverbauplatten können relativ lange als Sicherung stehen bleiben und benötigen nur geringe Kräfte um wieder aus dem Boden gezogen zu werden. Trotzdem ist es möglich, sie während des Rückbaues frei von Steifen zu halten, wodurch der Rückbau wesentlich erleichtert wird.The same applies to dismantling. The trench sheeting panels can remain and need a relatively long time as a backup only slight forces to be pulled out of the ground again. Nevertheless, it is possible to keep them free during dismantling To keep stiff, which makes dismantling much easier becomes.

Gemäß einer abgewandelten Ausführung kann die Kappe 5 auch die Schneide 1 ganz ersetzen und unmittelbar mit dem unteren Ende der Grabenverbauplatte 2 fest oder lösbar verbunden sein.According to a modified embodiment, the cap 5 can also completely replace the cutting edge 1 and can be directly or permanently connected to the lower end of the trench shoring plate 2 .
