Abstract
Description
Die Erfindung bezieht sich auf eine Vorrichtung zum Verbau tiefer Gräben, bestehend aus
- vertikalen Stützen, die zu beiden Seiten längs des Grabens in gleichen Abständen
paarweise einander gegenüberstehend anzuordnen sind,
- die an ihren beiden Seiten Führungskanäle für Verbauplatten aufweisen und
- die an ihren einander zugewandten Innenseiten je einen Führungskanal zur formschlüssigen Führung des Spreizrahmens aufweisen, wobei dieser Führungskanal über einen von zwei Flanschen gebildeten Spalt zugänglich ist und
- die zu beiden Seiten des Führungskanals Rollbahnen aufweisen, gegen die sich Rollen des Spreizrahmens abstützen,
- mindestens einem Spreizrahmen, der zwischen zwei Stützen eines Stützenpaares angeordnet ist, der über in die Führungskanäle der Stützen eingreifende Teile formschlüssig vertikal verschiebbar geführt ist und der an beiden den Stützen zugewandten Seiten um mindestens zwei im Abstand voneinander angeordnete Achsen sich drehende Rollen aufweist, die beim Heben oder Senken des Spreizrahmens oder der Stützen auf den Rollbahnen der Stütze abrollen,
- Verbauplatten, deren Ränder in den seitlichen Führungskanälen zweier benachbarter Stützen einer Grabenseite vertikal verschiebbar geführt sind.
- vertical supports which are to be arranged in pairs opposite to each other along the trench at equal intervals,
- which have guide channels for sheeting panels on both sides and
- which on their mutually facing inner sides each have a guide channel for positive guidance of the expansion frame, this guide channel being accessible via a gap formed by two flanges and
- which have runways on both sides of the guide channel, against which rollers of the expansion frame are supported,
- at least one expansion frame, which is arranged between two supports of a pair of supports, which is guided in a form-fit, vertically displaceable manner via parts engaging in the guide channels of the supports and which has rotating rollers on both sides facing the supports about at least two spaced axes, Roll up or lower the spreading frame or the supports on the runways of the support,
- Shoring panels, the edges of which are guided so that they can be moved vertically in the lateral guide channels of two adjacent supports on one side of the trench.
Eine Verbauvorrichtung dieser Art ist aus der DE 42 30 860 und der DE 44 04 812 bekannt. Die Stütze und deren Stützflansche bestehen aus Stahlblech. Auf diese Stützflansche stützen sich einerseits die Verbauplatten ab und andererseits die quer zum Graben stehenden Spreizrahmen, deren obere und untere Rollenpaare auf den Rollbahnen abrollen, wenn die Spreizrahmen und die Stützen beim Absenken in den Graben oder beim Hochziehen während des Rückbaus relativ zueinander bewegt werden. Der Führungskanal für die Spreizrahmen ist in der Mitte der Innenseite der Stützen angeordnet. Zu beiden Seiten dieses Führungskanals erstrecken sich die Rollbahnen, die von der Außenseite der Stützflansche gebildet sind. A shoring device of this type is from DE 42 30 860 and DE 44 04 812 known. The support and its support flanges are made of sheet steel. To this Support flanges support the shoring plates on the one hand and the crosswise on the other spreading frame for digging, the upper and lower pairs of rollers on the Roll runways roll when the spreading frame and the supports when lowering into the Digging or moving relative to each other while pulling up during dismantling become. The guide channel for the expansion frame is in the middle of the inside of the Columns arranged. The extend on both sides of this guide channel Runways that are formed from the outside of the support flanges.
Damit von den Stützen auch Zugkräfte auf den Spreizrahmen ausgeübt werden können, ist der Führungskanal an der Innenseite der Stütze durch Flansche teilweise geschlossen. Die Flansche bilden zwischen sich einen Spalt, durch den Teile des Spreizrahmens hindurchgreifen und die Flansche hintergreifen, so daß eine formschlüssige Führung erreicht wird.So that the supports also exert tensile forces on the expansion frame can, the guide channel on the inside of the support is partially flanged closed. The flanges form a gap between them through which parts of the Reach through the spreading frame and reach behind the flanges, so that a positive Leadership is achieved.
Bei den bekannten Verbauvorrichtungen dieser Art sind die in den Führungskanal formschlüssig eingreifenden Teile T-förmige Schienen, deren Flansche auf den Innenseiten der Flansche des Führungskanals gleiten.In the known shoring devices of this type are in the guide channel interlocking parts T-shaped rails, the flanges of which Slide inside the flanges of the guide channel.
Es hat sich gezeigt, daß bei Vorrichtungen zum Verbau tiefer Gräben nicht nur sehr hohe Druckkräfte auf den Spreizrahmen einwirken, sondern auch sehr hohe Zugkräfte, die von den die Flansche des Führungskanals hintergreifenden Teile des Spreizrahmens aufzunehmen sind. Diese Kräfte sind besonders groß im oberen Bereich des oberen Spreizrahmens, wenn beim Eintreiben eines Stützenpaares in das Erdreich diese nicht genau parallel zueinander stehen, sondern ihre unteren Enden einen kleineren Abstand voneinander haben als ihre oberen Enden. Diese Zugkräfte verursachen so große Reibungskräfte, daß ein Verschieben des Spreizrahmens relativ zu den Stützen erschwert ist.It has been shown that in devices for the construction of deep trenches not only very high compressive forces act on the expansion frame, but also very high Tractive forces, which of the parts of the Spreading frame must be included. These forces are particularly large in the upper one Area of the upper spreader frame when driving a pair of supports into the Soil these are not exactly parallel to each other, but their lower ends have a smaller distance from each other than their upper ends. These tractive forces cause such large frictional forces that the spreading frame moves is difficult relative to the supports.
Der Erfindung liegt die Aufgabe zugrunde, die Verbauvorrichtung der eingangs genannten Art so zu verbessern, daß der Spreizrahmen auch bei Aufnahme großer Zugkräfte leichtgängig in den Stützen vertikal geführt ist.The invention has for its object the installation device of the beginning mentioned type to improve so that the spreading frame even when recording large Tractive forces are easily guided vertically in the supports.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß zumindest im oberen Bereich des Spreizenrahmens an beiden den Stützen zugewandten Seiten je eine um eine horizontale Achse schwenkbare, durch den Spalt in den Führungskanal eingreifende Scheibe gelagert ist, an der innerhalb des Führungskanals im gleichen Abstand oberhalb und unterhalb des Niveaus der Schwenkachse horizontale Achsen angeordnet sind mit zu beiden Seiten der Scheibe befindlichen Rollen, die auf den Innenseiten der Flansche des Führungskanals abrollen.This object is achieved in that at least in the upper Area of the spreading frame one on each side facing the supports pivotable about a horizontal axis, through the gap into the guide channel engaging disc is mounted on the inside of the guide channel in the same Distance above and below the level of the swivel axis horizontal axes are arranged with rollers located on both sides of the disc, which on the Roll the inside of the flanges of the guide channel.
Die verschwenkbare Lagerung der Scheiben am Spreizrahmen bewirkt, daß die vier im Führungskanal befindlichen Rollen einer Scheibe gleich stark belastet werden. Obgleich im Führungskanal nur im Durchmesser kleine Rollen benutzt werden können, können die Rollen gemeinsam große Kräfte aufnehmen. The pivotable mounting of the panes on the expansion frame causes the four rollers of a disc located in the guide channel are equally loaded. Although only small diameter rollers are used in the guide channel can, the roles can absorb large forces together.
Die Schwenkachse für die Scheiben kann mit den Achsen der oberen, die Druckkräfte übertragenden Rollen zusammenfallen.The swivel axis for the disks can coincide with the axes of the upper ones, the compressive forces transferring roles coincide.
