Definitions

  • the invention relates to a shoring device for supporting the walls of a trench with a stepped cross-section, consisting of upper and lower pairs of large-area shoring panels, the lateral edges of which are slidably guided on supports which are arranged in pairs opposite one another at intervals along the trench and at a distance by means of cross struts are held and which have guide slots on both sides for receiving the edges of the shoring panels, the side of the trench wall facing the trench wall is formed by a guide flange of the support and the trench interior side of which is formed by a guide plane, the edges of the upper shoring panels and the guide slots of the supports being such are formed so that the edges of a cohesion of shoring plates and supports in the trench longitudinal direction are positively guided in the guide slots.

Description

Die Erfindung geht aus von einer Verbauvorrichtung zum Abstützen der Wände eines Grabens mit gestuftem Querschnitt, bestehend aus oberen und unteren Paaren großflächiger Verbauplatten, deren seitliche Ränder verschiebbar an Stützen geführt sind, die in Abständen längs des Grabens paarweise einander gegenüberstehend angeordnet und mittels Querstreben auf Abstand gehalten sind und die an beiden Seiten zur Aufnahme der Ränder der Verbauplatten Führungsschlitze aufweisen, deren der Grabenwand zugewandten Seite von einem Führungsflansch der Stütze und deren dem Grabeninneren zugewandten Seite von einer Führungsebene gebildet wird, wobei die Ränder der oberen Verbauplatten und die Führungsschlitze der Stützen derart ausgebildet sind, daß die Ränder einen Zusammenhalt von Verbauplatten und Stützen in Grabenlängsrichtung bewirkend formschlüssig in den Führungsschlitzen geführt sind. Die Führungsebene kann beispielsweise von einem zweiten Führungsflansch oder einer Reihe übereinander angeordneter, um horizontale Achsen drehbar gelagerter Rollen gebildet werden.The invention relates to a shoring device for supporting the walls of a trench with a stepped cross-section, consisting of upper and lower pairs of large-area shoring panels, the lateral edges of which are slidably guided on supports which are arranged in pairs opposite one another at intervals along the trench and at a distance by means of cross struts are held and which have guide slots on both sides for receiving the edges of the shoring panels, the side of the trench wall facing the trench wall is formed by a guide flange of the support and the trench interior side of which is formed by a guide plane, the edges of the upper shoring panels and the guide slots of the supports being such are formed so that the edges of a cohesion of shoring plates and supports in the trench longitudinal direction are positively guided in the guide slots. The guide plane can be formed, for example, by a second guide flange or a row of rollers arranged one above the other and rotatably mounted about horizontal axes.

Verbauvorrichtungen dieser Art sind bekannt aus der DE-OS 30 31 099.Shoring devices of this type are known from DE-OS 30 31 099.

Die bekannten Verbauvorrichtungen zum Abstützen der Wände eines Grabens mit gestuftem Querschnitt haben den Nachteil, daß die Stützen an beiden Seiten zwei zueinander parallele Führungsschlitze aufweisen müssen, nämlich einen Führungsschlitz für die unteren, inneren Platten und einen zweiten Führungsschlitz für die oberen, äußeren Platten. Die Herstellung dieser Stützen mit je zwei zueinander parallelen Führungsschlitzen an beiden Seiten ist aufwendig. Die Stützen werden durch die beiden Führungsschlitze unnötig schwer.The known shoring devices for supporting the walls of a trench with a stepped cross-section have the disadvantage that the supports must have two mutually parallel guide slots on both sides, namely a guide slot for the lower, inner plates and a second guide slot for the upper, outer plates. The production of these supports, each with two mutually parallel guide slots on both sides, is complex. The two guide slots make the supports unnecessarily heavy.

Aus der GB-A-2 018 857 ist eine Verbauvorrichtung bekannt, die als Ganzes in einen Graben einsetzbar ist und zwei über Spreizen miteinander verbundene Führungsrahmen für mehrere Verbautafeln aufweist. Ein Führungsrahmen setzt sich aus mehreren vertikalen Führungsschienen und diese Führungsschienen zu einem Rahmen verbindende horizontale Träger zusammen. Die Führungsschienen haben an den einander zugewandten Seiten U-förmige Führungsschlitze, in denen vertikal verschiebbar zwei Verbautafeln geführt sind. Jede Verbautafel ist aus einem derart kammartig gefalteten Blech gebildet, daß sie mit zahlreichen vorstehenden lotrechten Rippen versehen ist. Die Rippen der äußeren Verbautafel sind nach innen gerichtet, während die dazu versetzten Rippen der inneren Verbautafel nach außen gerichtet sind. Diese Rippen geben den Verbautafeln die erforderliche Festigkeit und dienen als Abstandhalter und Gleitleisten gegenüber der zugeordneten anderen Verbautafel eines Tafelpaares.From GB-A-2 018 857 a shoring device is known which can be inserted as a whole into a trench and has two guide frames for several shoring panels which are connected to one another by means of spreaders. A guide frame is composed of a plurality of vertical guide rails and horizontal supports connecting these guide rails to form a frame. The guide rails have U-shaped guide slots on the mutually facing sides, in which two shoring panels are guided so as to be vertically displaceable. Each shoring panel is formed from sheet metal folded in such a comb-like manner that it is provided with numerous protruding vertical ribs. The ribs of the outer shoring panel are directed inwards, while the ribs of the inner shoring panel offset to it are directed outwards. These ribs give the sheeting panels the required strength and serve as spacers and sliding strips compared to the associated other sheeting panels of a pair of panels.

Diese Verbautafeln befinden sich in Gebrauchsstellung im wesentlichen in gleicher Höhe, so daß die geschlossenen Wandflächen der Verbautafeln die vertikalen Rippen einschließen. Diese bekannte Verbauvorrichtung ist von anderer Art als die eingangs beschriebene Verbauvorrichtung, die nicht als Ganzes in einen Graben eingesetzt wird, sondern nacheinander jeweils ein Stützenpaar und mindestens ein Verbauplattenpaar.These shoring panels are at substantially the same height in the use position, so that the closed wall surfaces of the shoring panels enclose the vertical ribs. This known shoring device is of a different type than the shoring device described at the outset, which is not inserted as a whole into a trench, but rather one pair of supports and at least one pair of shoring plates in succession.

Aufgabe der vorliegenden Erfindung ist es, eine Verbauvorrichtung der eingangs genannten Art derart weiterzubilden, daß die Stützen einfacher gestaltet und weniger aufwendig sind als bei den bekannten Verbauvorrichtunge.The object of the present invention is to develop a shoring device of the type mentioned at the outset in such a way that the supports are of simpler design and are less complex than in the known shoring devices.

Diese Aufgabe wird gelöst durch die Merkmale des Patentanspruches 1.This object is achieved by the features of patent claim 1.

Bei der erfindungsgemäßen Verbauvorrichtung haben die Stützen an jeder Seite nur noch einen Führungsschlitz und nur eine Führungsebene, auf welcher sich die Ränder der oberen, äußeren Verbauplatten und der inneren, unteren Verbauplatten abstützen.In the shoring device according to the invention, the supports have only one guide slot on each side and only one guide plane on which the edges of the upper, outer shoring panels and the inner, lower shoring panels are supported.

Vorteilhafterweise wird die Führungsebene von zwei Reihen an den Stützen um waagerechte Achsen drehbar gelagerter Rollen gebildet. Diese Rollen für die oberen, äußeren Verbauplatten und für die unteren, inneren Verbauplatten können auf gemeinsamen Achsen gelagert sein. Die erfindungsgemäße Verbauvorrichtung hat den Vorteil, daß sie nicht nur für den Verbau eines Grabens mit gestuftem Querschnitt geeignet ist, sondern auch für den Verbau eines Grabens mit Rechteckquerschnitt. In diesem Falle werden in die Stützen zwei mit vorspringenden Rändern versehene Verbauplatten übereinander eingeführt. Ein derartiger Verbau hat den Vorteil, daß der Arbeitsraum im Bereich der Grabensohle größer ist als bei einem abgestuftem Verbau.The guide plane is advantageously formed by two rows of rollers rotatably mounted on the supports about horizontal axes. These rollers for the upper, outer shoring panels and for the lower, inner shoring panels can be mounted on common axes. The shoring device according to the invention has the advantage that it is not only suitable for shoring a trench with a stepped cross section, but also for shoring a trench with a rectangular cross section. In this case, two shoring plates with projecting edges are inserted one above the other in the supports. Such a shoring has the advantage that the working space in the area of the trench bottom is larger than with a stepped shoring.

Sofern man aber die unteren Verbauplatten unabhängig von den oberen Verhauplatten in den Graben einsetzen möchte oder aus dem Graben herausziehen möchte, ist ein abgestufter Verbau notwendig.However, if you want to insert the lower shoring panels into the trench independently of the upper covering panels or if you want to pull them out of the trench, a graded shoring is necessary.

Weitere Merkmale ergeben sich aus den Patentansprüchen. In der folgenden Beschreibung wird die Erfindung unter Bezugnahme auf die in den Zeichnungen dargestellten Ausführungsbeispiele näher erläutert. Es zeigen:

  • Fig. 1 eine Draufsicht auf ein Stützenpaar mit in die Stützen eingeführten Verbauplatte,
  • Fig. 2 eine Stirnansicht eines in einen Graben eingesetzten Stützenpaares,
  • Fig. 3 eine Draufsicht auf eine Stütze mit in die Führungsschlitze eingeführten Verbauplatten,
  • Fig. 4 eine Draufsicht auf eine weitere Ausführungsform einer Stütze mit in die Führungsschlitze eingeführten Verbauplatten.
Further features emerge from the patent claims. The invention is explained in more detail in the following description with reference to the exemplary embodiments illustrated in the drawings. Show it:
  • 1 is a plan view of a pair of supports with a shoring plate inserted into the supports,
  • 2 shows an end view of a pair of supports inserted into a trench,
  • 3 is a plan view of a support with sheeting plates inserted into the guide slots,
  • Fig. 4 is a plan view of a further embodiment of a support with sheeting plates inserted into the guide slots.

Die in den Fig. 1, und 3 dargestellte Verbauvorrichtung setzt sich aus paarweise einander gegenüberstehend angeordneten Stützen 1 zusammen, in welche großflächige Verbauplatten 2 und 3 vertikal verschiebbar geführt sind. Die paarweise einander gegenüberstehenden Stützen werden mittels Querstreben 4 und 5 auf Abstand gehalten. Diese Querstreben 4 und 5 können Steifen sein, sie können aber auch - wie dargestellt- als Spreizen ausgebildet sein. An beiden Seiten der Stützen 1 sind Führungsschlitze 6 angeordnet, deren der Grabenwand zugewandten Seiten von einem Führungsflansch 7 der Stütze 1 und deren dem Grabeninneren zugewandten Seite von einer Führungsebene 8 gebildet wird. In den Fig. 1 und 2 wird die Führungsebene 8 eines Führungsschlitzes 6 von einer Reihe, um waagerechte Achsen 10 drehbar gelagerter Rollen 11, 12 gebildet. Der Abstand der Führungsebene 8 von der Innenseite der Führungsflansche 7 ist um 50 bis 150% größer als die Dicke einer Verbauplatte 2 oder 3. Die beim Stufenverbau obere und äußeren Verbauplatte 2 weist einen zwischen dem Führungsflansch 7 und der Führungsebene 8 geführten Rand 9 auf, der zur Führungsebene 8 hin vorspringt. Zwischen der oberen, äußeren Verbauplatte 2 und der Führungsebene 8 wird auf diese Weise Platz gewonnen, um zwischen der äußeren Verbauplatte 2 und der Führungsebene 8 eine innere Verbauplatte 3 einführen zu können, deren seitliche Ränder sich ebenfalls auf der Führungsebene 8 abstützen. Die innere Verbauplatte 3 ist um mehr als die doppelte Breite eines vorspringenden Randes der äußeren Verbauplatte 2 kürzer.The shoring device shown in FIGS. 1 and 3 is composed of supports 1 arranged in pairs opposite one another, into which large-area shoring panels 2 and 3 can be displaced vertically are led. The pairs of opposing supports are kept at a distance by means of cross struts 4 and 5. These cross struts 4 and 5 can be stiffeners, but they can also - as shown - be designed as spreaders. Guide slots 6 are arranged on both sides of the supports 1, the sides of which facing the trench wall are formed by a guide flange 7 of the support 1 and the side facing the interior of the trench is formed by a guide plane 8. 1 and 2, the guide plane 8 of a guide slot 6 is formed by a row of rollers 11, 12 rotatably mounted about horizontal axes 10. The distance of the guide plane 8 from the inside of the guide flanges 7 is 50 to 150% greater than the thickness of a shoring plate 2 or 3. The upper and outer shoring plate 2 during step installation has an edge 9 guided between the guide flange 7 and the guide plane 8, that projects to management level 8. In this way, space is gained between the upper, outer shoring plate 2 and the guide level 8 in order to be able to insert an inner shoring plate 3 between the outer shoring plate 2 and the guide level 8, the lateral edges of which are also supported on the guide level 8. The inner lining plate 3 is shorter by more than twice the width of a projecting edge of the outer lining plate 2.

Wenn die Führungsebene 8 durch um Achsen 10 umlaufende Rollen gebildet wird, dann können die Ränder der äußeren Verbauplatte und der inneren Verbauplatte auf gleichen Rollen 11' ablaufen. Es ist aber vorteilhaft, die Rollen zu teilen, so daß die vorspringenden Ränder der äußeren Verbauplatte 2 auf den Rollen 11 abrollen, während die Ränder der inneren Verbauplatte 3 auf Rollen 12 abgestützt sind.If the guide plane 8 is formed by rollers rotating around axes 10, the edges of the outer shoring plate and the inner shoring plate can run on the same rollers 11 '. However, it is advantageous to divide the rollers so that the projecting edges of the outer lining plate 2 roll on the rollers 11, while the edges of the inner lining plate 3 are supported on rollers 12.

Anstelle der Rollen 11 und 12 können aber auch Gleitkufen oder aber auch Flansche der Stützen 1 vorgesehen sein.Instead of the rollers 11 and 12, skids or flanges of the supports 1 can also be provided.

An den äußeren Enden der Führungsflansche 7 der Stützen 1 sind Leisten 19 angeordnet, die mit Leisten 20 zusammenwirken, welche an den äußeren Seitenrändern der Verbauplatte 2 angeordnet sind und die bewirken, daß die oberen, äußeren Verbauplatten 2 formschlüssig in den Stützen 1 geführt sind, so daß ein Zusammenhalt von Verbauplatten 2 und Stützen 1 in Grabenlängsrichtung gewährleistet ist.At the outer ends of the guide flanges 7 of the supports 1, strips 19 are arranged, which cooperate with strips 20, which are arranged on the outer side edges of the shoring plate 2 and which have the effect that the upper, outer shoring plates 2 are positively guided in the supports 1, so that cohesion of shoring plates 2 and supports 1 is guaranteed in the longitudinal direction of the trench.

Wie die Fig. 3 zeigt, weist die Stütze 1 zwei im Abstand voneinander befindliche Seitenwände 13 und 14 auf, die an der Grabenaußenseite über eine, die beiden Führungsflansche 7 bildende Außenwand 15 sowie über mindestens eine Reihe von angeschweißten Rohren 16 miteinander verbunden sind. Durch die beiden Seitenwände 13 und 14 verbindende Rohre 16 können die Achsen 10 gesteckt werden, auf welchen die Rollen 11 und 12 drehbar gelagert sind. Zwischen den Seitenwänden 13 und 14 der Stütze 1 können die Köpfe der Querstreben 4 und 5 um waagerechte Achsen schwenkbar gelagert sein. Auch die Verbindungsrohre 16 können als Schwenkachsen für die Querstreben bzw. Spreizen 4 und 5 dienen.As shown in FIG. 3, the support 1 has two spaced-apart side walls 13 and 14 which are connected to one another on the outside of the trench via an outer wall 15 forming the two guide flanges 7 and at least one row of welded pipes 16. The axles 10 on which the rollers 11 and 12 are rotatably mounted can be inserted through the two side walls 13 and 14 connecting tubes 16. Between the side walls 13 and 14 of the support 1, the heads of the cross struts 4 and 5 can be pivotally mounted about horizontal axes. The connecting tubes 16 can also serve as pivot axes for the cross struts or spreaders 4 and 5.

Die Stützen 1 sind zwischen den Seitenwänden 13 und 14 an der Innenseite offen. An dieser offenen Seite sind die Seitenwände 13 und 14 mit nach außen gerichteten Verstärkungswülsten 17 versehen. Auf diese Weise erhält die Stütze 1 eine hohe Biegesteifigkeit. An diesen Wülsten 17 sind Stützbleche 18 angeschweißt, die die Enden der Achsen 10 abstützen.The supports 1 are open between the side walls 13 and 14 on the inside. On this open side, the side walls 13 and 14 are provided with reinforcing beads 17 directed outwards. In this way, the support 1 receives a high degree of bending rigidity. On these beads 17 support plates 18 are welded, which support the ends of the axes 10.

In Fig. 1 ist der Abstand der Führungsebene 8 von der Innenseite der Führungsflansche 7 mehr als doppelt so groß wie die Dicke einer Verbauwand 2 oder 3. Bei der Stütze 1 gemäß Fig. 3 ist der Abstand der Führungsebene 8 von den Flanschen 7 kleiner als die doppelte Dicke einer Verbauwand, weil an den inneren Platten 3 ein Führungsrand 21 befestigt ist, dessen Dicke nur etwa halb so groß ist wie die Dicke der inneren Verbauplatte 3.In Fig. 1, the distance of the guide plane 8 from the inside of the guide flanges 7 is more than twice the thickness of a shoring wall 2 or 3. In the support 1 according to FIG. 3, the distance of the guide plane 8 from the flanges 7 is less than twice the thickness of a shoring wall, because a guide edge 21 is fastened to the inner plates 3, the thickness of which is only about half as large as the thickness of the inner shoring plate 3.

Weil die äußeren Verbauplatten 2 durch die aufgesetzten, über die gesamte Plattenhöhe verlaufenden Ränder 9 verstärkt sind, ist es zweckmäßig, die Höhe dieser Verbauplatten 2 größer zu wählen als die Höhe der inneren Verbauplatten 3.Because the outer shoring panels 2 are reinforced by the attached edges 9 running over the entire panel height, it is expedient to choose the height of these shoring panels 2 to be greater than the height of the inner shoring panels 3.

In Fig. 4 ist eine Verbauvorrichtung nach der Erfindung dargestellt, bei welcher die normalerweise außen und oben anzuordnenden Verbauplatten auch innenseitig angeordnet werden können, indem sie um 180° um eine horizontale Achse gedreht werden. Bei diesem Ausführungsbeispiel haben die einzelnen Teile, soweit sie gleichwirkend sind, die gleichen Bezugszeichen wie bei dem Ausführungsbeispiel nach Fig. 3, jedoch sind diese Bezugszeichen mit einem Strich versehen. Die Plattenkörper der Verbauplatten 2' und 3' sind völlig gleich ausgebildet und die Randbereiche 32 und 33 sind als vorgefertigte Teile an diesen Verbauplattenkörpern befestigt. Diese vorgefertigten Randbereiche 32, 33 können an die gleich ausgebildeten Verbauplattenkörper angeschweißt werden oder aber auch angeschraubt werden, wenn eine lösbare Verbindung erwünscht ist.4 shows a shoring device according to the invention, in which the shoring panels which are normally to be arranged on the outside and above can also be arranged on the inside by being rotated through 180 ° about a horizontal axis. In this exemplary embodiment, the individual parts, insofar as they have the same effect, have the same reference symbols as in the exemplary embodiment according to FIG. 3, but these reference symbols are provided with a dash. The plate bodies of the shoring panels 2 'and 3' are of completely identical design and the edge regions 32 and 33 are fastened to these shoring panel bodies as prefabricated parts. These prefabricated edge areas 32, 33 can be welded to the same-shaped shoring panel body or can also be screwed on if a detachable connection is desired.

Der Randbereich 32 der Verbauplatte 2' weist einen Stützrand 34 auf, der aus einem relativ dicken Stahlblech gebildet ist. Wird die Verbauplatte 2' als obere äußere Platte in den Führungsschlitz 6 der Stütze 1' eingeschoben, dann stützt sich die vorspringende Kante des Stützrandes auf der Führungsebene 8, die von einer Reihe von Rollen 11' gebildet wird, ab. Die andere Kante des Stützrandes 34 ist zwischen der Seitenwand 14 und der Leiste 19' geführt. Im Vergleich zu den vorher beschriebenen Ausführungsbeispielen hat die Kante 42 der Leiste 19' einen größeren Abstand vom Führungsflansch 7'. Zwischen der Leiste 19' und den Seitenwänden 13' und 14' der Stütze 1' sind Führungsbleche 43 angeordnet, an welche die Kanten des Stützrandes 34 gleiten können. Die Außenseite 37 der Verbauplatte 2' ist derart in bezug zur Führungsebene 8 und in bezug auf die darauf sich abstützenden Anlageflächen des Stützrandes 34 angeordnet, daß die Außenseite 37 der Verbauplatte 2' mit der Außenseite 36 der Stütze 1' fluchtet, wenn die Platte als äußere obere Verbauplatte in den Führungsschlitz 6 eingeführt wird. Die untere innere Platte 3' ist so ausgebildet, daß die Innenseite 38 dieser Platte mit der Innenseite der Stütze 1' fluchtet, wenn der Randbereich 33 auf der Führungsebene 8 bzw. auf die Rollenreihe 11' aufliegt.The edge region 32 of the shoring plate 2 'has a support edge 34 which is formed from a relatively thick steel sheet. If the shoring plate 2 'is inserted as the upper outer plate into the guide slot 6 of the support 1', then the projecting edge of the support edge is supported on the guide plane 8, which is formed by a row of rollers 11 '. The other edge of the support edge 34 is guided between the side wall 14 and the bar 19 '. In comparison to the previously described exemplary embodiments, the edge 42 of the strip 19 'is at a greater distance from the guide flange 7'. Between the bar 19 'and the side walls 13' and 14 'of the support 1' guide plates 43 are arranged, on which the edges of the support edge 34 can slide. The The outside 37 of the shoring plate 2 'is arranged in relation to the guide plane 8 and in relation to the contact surfaces of the supporting edge 34 which rest on it so that the outside 37 of the shoring plate 2' is aligned with the outside 36 of the support 1 'when the plate is external upper shoring plate is inserted into the guide slot 6. The lower inner plate 3 'is designed such that the inside 38 of this plate is flush with the inside of the support 1' when the edge region 33 rests on the guide plane 8 or on the row of rollers 11 '.

Wie Fig. 4 zeigt, ist in den anderen Führungsschlitz 6 der Stütze 1' nur eine Verbauplatte 2' eingeführt, jedoch ist diese Verbauplatte gegenüber der ersten Verbauplatte 2' um 180° um eine horizontale Achse gedreht. In dieser Stellung der Verbauplatte 2' fluchtet die Außenseite 37 der Verbauplatte 2' mit der Innenseite der Stütze 1'. Bei dieser Ausführung können auch zwei oder mehrere Verbauplatten übereinander in die Führungsschlitze 6 der Stütze 1' eingeschoben werden. Diese Ausbildung hat den Vorteil, daß die Verbauvorrichtung auch benutzt werden kann, wenn ein gestufter Grabenquerschnitt nicht erforderlich oder nicht erwünscht ist. Ferner hat diese Ausführungsform den Vorteil, daß zum Beispiel beim Ausbetonieren der Grabensohle keine an der Innenseite vorspringende Teile der Stütze vorhanden sind und daß beim Verbau eines Grabens mit gestuftem Querschnitt keine Stützenteile in die Flucht der Grabenwand vorspringen.As shown in FIG. 4, only one shoring plate 2 'is inserted into the other guide slot 6 of the support 1', but this shoring plate is rotated by 180 ° about a horizontal axis with respect to the first shoring plate 2 '. In this position of the shoring plate 2 ', the outside 37 of the shoring plate 2' is aligned with the inside of the support 1 '. In this embodiment, two or more shoring panels can also be inserted one above the other into the guide slots 6 of the support 1 '. This design has the advantage that the shoring device can also be used when a stepped trench cross section is not required or is not desired. Furthermore, this embodiment has the advantage that, for example when concreting the trench bottom, there are no protruding parts of the support on the inside and that when a trench with a stepped cross section is built, no support parts project into the alignment of the trench wall.

Zwischen den beiden Seitenwänden 13' und 14' der Stützen 1 sind zur Queraussteifung Bleche 39 eingeschweißt. An der Innenseite des Grabens sind die Bleche, welche die Seitenwände 13' und 14' der Stütze 1' bilden U-förmig zu den Seiten umgebogen, so daß U-förmige Rollenschienen 40 entstehen, zwischen deren parallele Stege die Rollen 11' beidseitig gelagert sind. Zur Versteifung dieser Rollenschienen 40 sind in den Lücken zwischen den Rollen 11' horizontale Bleche 41 eingeschweißt. Ferner können noch senkrecht verlaufende Versteifungsbleche 44 vorgesehen sein, welche die Innenseite der Stege der U-förmigen Schiene 40 miteinander verbinden. Auf diese Weise wird verhindert, daß auch bei extrem großer Belastung der Führungsebene 8 die Schienen 40 sich nicht aufbiegen. Um ein Abknicken der Stützränder 40 zu vermeiden, sind im Winkel zwischen der Innenseite des Stützrandes 34 und der Innenseite der Verbauplatte 2' Verstei fungsbleche 35 vorgesehen.Sheets 39 are welded in between the two side walls 13 'and 14' of the supports 1 for transverse reinforcement. On the inside of the trench, the sheets which form the side walls 13 'and 14' of the support 1 'are bent in a U-shape to the sides, so that U-shaped roller rails 40 are formed, between the parallel webs of which the rollers 11' are mounted on both sides . In order to stiffen these roller rails 40, horizontal metal sheets 41 are welded into the gaps between the rollers 11 '. Furthermore, vertically extending stiffening plates 44 can be provided which connect the inside of the webs of the U-shaped rail 40 to one another. In this way it is prevented that the rails 40 do not bend even when the guide plane 8 is subjected to extremely high loads. In order to avoid kinking of the support edges 40, reinforcement plates 35 are provided at an angle between the inside of the support edge 34 and the inside of the shoring plate 2 '.
