Description

Die Erfindung bezieht sich auf eine Verbauvorrichtung mit paarweise einander gegenüberliegend angeordneten großflächigen Verbauplatten, welche gegen paarweise einander gegenüberliegend angeordnete vertikale Stützen abgestützt sind, die von mindestens einem Spreizrahmen auf Abstand gehalten sind, wobei die Stützen von ihren Seitenwänden parallel zur Basiswand abgewinkelte, gegeneinander gerichtete und einen breiten Spalt zwischen sich freilassende Schenkel aufweisen und in den Spalten einander gegenüberliegender Stützen der Spreizrahmen vertikal verschiebbar und horizontal formschlüssig mittels Druckkräfte des Spreizrahmens übertragende und auf der Basiswand der Stützen ablaufende Rollen und mittels Zugkräfte des Spreizrahmens übertragende und auf den Innenseiten der beiden Schenkel einer Stütze ablaufenden Rollen geführt ist.The invention relates to a shoring device with pairs of mutually opposed large-area shoring panels, which are supported against pairs of oppositely arranged vertical supports, which are kept at a distance from at least one expansion frame, the supports angled from their side walls parallel to the base wall, facing each other and have a wide gap between the legs that are left free and in the columns of mutually opposite supports the expansion frame can be displaced vertically and horizontally positively by means of pressure forces of the expansion frame and transferring on the base wall of the supports and by means of tensile forces of the expansion frame transmitting and on the inside of the two legs of a support running roles is performed.

Verbauvorrichtungen dieser Art sind bekannt aus dem deutschen Gebrauchsmuster 74 35 632.Shoring devices of this type are known from German utility model 74 35 632.

Bei den bekannten Verbauvorrichtungen sind die Druckkräfte übertragenden Rollen auf Achsen gelagert, die zwischen der oberen und unteren Querstrebe des Stützrahmens an der linken und rechten Vertikalstrebe des Stützrahmens angeordnet sind. Die Zugkräfte des Spreizrahmens übertragenden Rollen sind in Höhe der oberen und unteren Querstrebe des Stützrahmens an der rechten und linken Vertikalstrebe des Stützrahmens angeordnet.In the known shoring devices, the pressure-transmitting rollers are mounted on axles which are arranged between the upper and lower cross struts of the support frame on the left and right vertical struts of the support frame. The tensile forces of the spreading frame rollers are arranged at the level of the upper and lower cross struts of the support frame on the right and left vertical struts of the support frame.

Die in der Höhe versetzte Anordnung der Druckkräfte übertragenden Rollen und der Zugkräfte übertragenden Rollen hat einen hohen Montageaufwand und einen größeren Materialaufwand zur Folge. Ferner ist auch die Anordnung der die Druckkräfte übertragenden Rollen zwischen den die Zugkräfte übertragenden Rollen ungünstig, weil dadurch die Spreizrahmen nicht optimal in den Stützen geführt sind.The offset arrangement of the pressure-transmitting rollers and the tensile-force rollers results in a high installation effort and a greater material expenditure. Furthermore, there is also the arrangement of the rollers transmitting the compressive forces between the tensile forces transferring roles unfavorable because the expansion frames are not optimally guided in the supports.

Der Erfindung liegt die Aufgabe zugrunde, eine Verbauvorrichtung zu schaffen, die mit geringerem Montage- und Materialaufwand eine zuverlässige Führung der Spreizrahmen in den Stützen der Verbauvorrichtung gewährleistet.The invention has for its object to provide a shoring device that ensures reliable guidance of the expansion frame in the supports of the shoring device with less installation and material.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Druckkräfte übertragenden Rollen und die Zugkräfte übertragenden Rollen auf gemeinsamen Achsen angeordnet sind, wobei die Druckkräfte übertragenden Rollen im Spalt zwischen den Schenkeln einer Stütze angeordnet sind und im Durchmesser größer sind als der Abstand dieser Schenkel von der Basiswand der Stütze und die Zugkräfte übertragenden Rollen im Durchmesser kleiner sind und an den jeweils nach außen gerichteten Seiten der Druckkräfte übertragenden Rollen angeordnet sind.This object is achieved in that the pressure-transmitting rollers and the tensile-transmitting rollers are arranged on common axes, the pressure-transmitting rollers being arranged in the gap between the legs of a support and in diameter larger than the distance of these legs from the base wall the support and the tensile force-transmitting rollers are smaller in diameter and are arranged on the outwardly directed sides of the compressive force-transmitting rollers.

Die erfindungsgemäße Ausführung der Verbauvorrichtung hat den Vorteil, daß an jeder seitlichen Vertikalstrebe des Spreizrahmens nur zwei Achsen anzuordnen sind, auf denen die Druckkräfte übertragenden Rollen und die Zugkräfte übertragenden Rollen angeordnet werden. Die oberen und unteren Rollen des Spreizrahmens können dabei einen möglichst großen Abstand voneinander haben, so daß eine optimale Führung der Spreizrahmen in den Stützen gewährleistet ist.The embodiment of the shoring device according to the invention has the advantage that only two axes are to be arranged on each lateral vertical strut of the expansion frame, on which the pressure-transmitting rollers and the tensile-force rollers are arranged. The upper and lower rollers of the spreader frame can have the greatest possible distance from one another, so that optimal guidance of the spreader frame in the supports is ensured.

Weitere Merkmale ergeben sich aus den Unteransprüchen 2 bis 8.Further features emerge from subclaims 2 to 8.

In der folgenden Beschreibung wird ein Ausführungsbeispiel der Erfindung unter Bezugnahme auf die Zeichnungen näher erläutert. Die Zeichnungen zeigen in

  • Fig. 1 eine Seitenansicht der erfindungsgemäßen Verbauvorrichtung und
  • Fig. 2 eine Ansicht nach der Schnittlinie II-II in Fig. 1.
In the following description, an embodiment of the invention is explained in more detail with reference to the drawings. The drawings show in
  • Fig. 1 is a side view of the shoring device according to the invention and
  • 2 is a view along the section line II-II in Fig. 1st

Nach Fig. 1 setzt sich die Verbauvorrichtung zur Abstützung der im wesentlichen senkrechten Wände eines ausgehobenen Grabens zusammen aus großflächigen, paarweise einander gegenüberliegend angeordneten Verbauplatten 2 und 4, welche gegen paarweise einander gegenüberliegend angeordnete vertikale Stützen 1 und 3 abgestützt sind. Die Stützen 1 und 3 der Verbauvorrichtung sind von mindestens einem Spreizrahmen 5 auf Abstand gehalten. Der Spreizrahmen 5 setzt sich zusammen aus einer oberen Querstrebe 6, einer unteren Querstrebe 7, einer linken Vertikalstrebe 8 und einer rechten Vertikalstrebe 9. An den beiden Vertikalstreben 8 und 9 sind Rollen 11 angeordnet, mit denen der Spreizrahmen 5 vertikal verschiebbar in den Stützen 1 und 3 geführt ist. An den unteren und oberen Enden der Stützen 1 und 3 sind Anschläge 13 und 14 einsetzbar, die verhindern, daß der Spreizrahmen 5 unbeabsichtigt aus einer der beiden Stützen 1 und 3 herausgleitet.According to FIG. 1, the shoring device for supporting the essentially vertical walls of an excavated trench is composed of large-area shoring plates 2 and 4 which are arranged opposite one another in pairs and which are supported against vertical supports 1 and 3 arranged opposite one another in pairs. The supports 1 and 3 of the shoring device are kept at a distance from at least one expansion frame 5. The expansion frame 5 is composed of an upper cross strut 6, a lower cross strut 7, a left vertical strut 8 and a right vertical strut 9. On the two vertical struts 8 and 9, rollers 11 are arranged, with which the expansion frame 5 is vertically displaceable in the supports 1 and 3 is performed. At the lower and upper ends of the supports 1 and 3, stops 13 and 14 can be used, which prevent the expansion frame 5 from accidentally sliding out of one of the two supports 1 and 3.

Beim Ausführungsbeispiel nach Fig. 1 werden die obere und untere Querstrebe 6 und 7 des Spreizrahmens 5 von längenveränderbaren Spreizen gebildet, so daß der Abstand der vertikalen Streben 8 und 9 voneinander einstellbar ist. Beim Einstellen der Breite des Spreizrahmens 5 ist dabei darauf zu achten, daß die Vertikalstreben 8 und 9 des Rahmens 5 genau parallel stehen oder nicht mehr als 1° nach unten konvergieren. Diese annähernde Parallelität ist präzise einzuhalten, weil sonst der Spreizrahmen 5 in den Stützen 1 und 3 verklemmt. Ein leichtes Konvergieren der Stützen 1 und 3 ist nicht so schädlich, weil der Spreizrahmen 5 mit größeren Kräften nach unten gedrückt werden kann als nach oben gezogen werden kann. Divergieren die Stützen nach oben, dann ist dennoch ein Herausziehen des Spreizrahmens 5 aus seinen Führungen ohne weiteres möglich. An den oberen Enden der vertikalen Streben 8 und 9 des Spreizrahmens 5 sind Konsolen 23 und 24 angeordnet, auf die ein Balken auflegbar ist und mit dessen Hilfe es möglich ist, beispielsweise mittels eines Baggerlöffels den Spreizrahmen 5 in den Stützen 1 und 3 nach unten zu drücken.In the embodiment according to FIG. 1, the upper and lower cross struts 6 and 7 of the expansion frame 5 are formed by variable-length spreaders, so that the distance between the vertical struts 8 and 9 can be adjusted from one another. When adjusting the width of the spreading frame 5, care must be taken that the vertical struts 8 and 9 of the frame 5 are exactly parallel or do not converge more than 1 ° downwards. This approximate parallelism must be observed precisely, otherwise the expansion frame 5 will jam in the supports 1 and 3. A slight convergence of the supports 1 and 3 is not so harmful because the expansion frame 5 can be pressed down with greater forces than can be pulled up. If the supports diverge upwards, pulling the expansion frame 5 out of its guides is still possible. At the top of the Vertical struts 8 and 9 of the expansion frame 5 are arranged brackets 23 and 24, on which a bar can be placed and with the help of which it is possible, for example by means of an excavator spoon, to press the expansion frame 5 in the supports 1 and 3 downwards.

Wie die Fig. 2 zeigt, haben die Stützen 1 und 3 ein C-förmiges Profil. Mit der Basiswand 12 liegt die Stütze 1 an der Innenwand der Verbauplatte 2 an. An beiden seitlichen Rändern der Verbauplatte 2 ist je eine Stütze 1 bzw. 3 befestigt bzw. angeschweißt.As shown in Fig. 2, the supports 1 and 3 have a C-shaped profile. With the base wall 12, the support 1 rests on the inner wall of the shoring panel 2. A support 1 or 3 is attached or welded to each of the two lateral edges of the shoring plate 2.

Von der Basiswand 12 der Stützen 1 und 3 sind rechtwinklig Seitenwände 15 und 15' abgewinkelt, und von diesen Seitenwänden 15 und 15' sind rechtwinklig die Schenkel 16 und 16' abgewinkelt. Die beiden Schenkel 16 und 16' sind gegeneinandergerichtet und lassen einen großen Spalt frei, durch den der Spreizrahmen 5 in die Stütze 1 bzw. 3 eingreift.Side walls 15 and 15 'are angled at right angles from the base wall 12 of the supports 1 and 3, and the legs 16 and 16' are angled at right angles from these side walls 15 and 15 '. The two legs 16 and 16 'are directed towards each other and leave a large gap through which the expansion frame 5 engages in the support 1 and 3, respectively.

Wie die Fig. 1 zeigt, sind in Höhe der oberen und unteren Querstrebe 6 und 7 an den Vertikalstreben 8 und 9 Achsen 10 befestigt, auf welche die auf der Basiswand 12 der Stützen 1 und 3 ablaufenden Rollen 11 und 11' gelagert sind.1 shows, at the level of the upper and lower cross struts 6 and 7 on the vertical struts 8 and 9 axles 10 are fastened, on which the rollers 11 and 11 'running on the base wall 12 of the supports 1 and 3 are mounted.

Wie die Fig. 2 zeigt, sind aber auch auf den Achsen 10 die Rollen 17 und 17' gelagert, welche die im Spreizrahmen 5 wirkenden Zugkräfte auf die Flansche 16 und 16' der Stützen 1 und 3 übertragen. Die Druckkräfte übertragenden Rollen 11 und 11' sind im Durchmesser größer als der Abstand der Basiswand 12 von den Schenkeln 16 und 16'. Deshalb sind diese Druckkräfte übertragenden Rollen 11 und 11' im Spalt zwischen den gegeneinander gerichteten Schenkeln 16 und 16' der Stützen 1 und 3 angeordnet. Die Zugkräfte übertragenden Rollen 17 und 17' sind im Durchmesser kleiner und an den jeweils nach außen gerichteten Seiten der Druckkräfte übertragenden Rollen 11 und 11' angeordnet. Dabei sind die Durchmesser der Rollen 11 und 17 bzw. 11' und 17' so gewählt, daß bei Anlage der Druckkräfte übertragenden Rollen 11,11' an der Basiswand 12 die Zugkräfte übertragenden Rollen 17 und 17' einen kleinen Abstand haben von den Innenseiten der Schenkel 16 und 16' der Stützen 1 und 3.As shown in FIG. 2, the rollers 17 and 17 'are also mounted on the axles 10, which transmit the tensile forces acting in the expansion frame 5 to the flanges 16 and 16' of the supports 1 and 3. The rollers 11 and 11 'which transmit pressure forces are larger in diameter than the distance between the base wall 12 and the legs 16 and 16'. Therefore, these pressure-transmitting rollers 11 and 11 'are arranged in the gap between the opposing legs 16 and 16' of the supports 1 and 3. The rollers 17 and 17 'which transmit tensile forces are smaller in diameter and are arranged on the respectively outwardly directed sides of the rollers 11 and 11' which transmit pressure forces. The diameters of the rollers 11 and 17 or 11 'and 17' are selected so that that when the pressure-transmitting rollers 11, 11 'rest on the base wall 12, the tensile-force rollers 17 and 17' are at a small distance from the inside of the legs 16 and 16 'of the supports 1 and 3.

Vorteilhafterweise ist je eine Druckkräfte übertragende Rolle 11 bzw. 11' und eine Zugkräfte übertragende Rolle 17 bzw. 17' einstückig miteinander verbunden.Advantageously, a pressure-transmitting roller 11 or 11 'and a tension-transmitting roller 17 or 17' are integrally connected to one another.

An beiden Seiten des Spreizrahmens 5 befinden sich zwei im Abstand voneinander befindliche vertikale Wände 19 und 19', in welche die Achsen 10 eingesetzt und angeschweißt sind und auf deren überkragenden Enden die Rollen 11,17 und 11',17' drehbar gelagert sind. An beiden Enden der Achse 10 sind Anlaufringe 18 und 18' angeschweißt, welche die Rollen 11,17 und 11',17' auf der Achse 10 halten. Die Basiswand 12 bzw. die Stütze 1 bzw. 3 ist etwa dreimal so breit wie eine Seitenwand 15 bzw. 15' einer Stütze 1 bzw. 3. Diese Stützen sind an den Rändern der Verbauplatte anzuordnen, so daß die Verbaueinheit eine sogenannte randgestützte Verbaueinheit bildet. Es ist aber auch möglich, die erfindungsgemäße Ausführung von Stützen und Spreizenrahmen zur mittigen Abstützung der Verbauplatten zu verwenden.On both sides of the expansion frame 5 there are two vertical walls 19 and 19 ', at a distance from one another, into which the axes 10 are inserted and welded and on the projecting ends of which the rollers 11, 17 and 11', 17 'are rotatably mounted. Thrust rings 18 and 18 'are welded to both ends of the axle 10 and hold the rollers 11, 17 and 11', 17 'on the axle 10. The base wall 12 or the support 1 or 3 is about three times as wide as a side wall 15 or 15 'of a support 1 or 3. These supports are to be arranged on the edges of the shoring plate, so that the shoring unit forms a so-called edge-supported shoring unit . However, it is also possible to use the design of supports and spreading frames according to the invention for central support of the shoring panels.
