Definitions
- the invention relates to a spreading strut for forming a Sp Dreckhornens for shoring devices according to the preamble of claim 1 and with this spreading strut formed Sp Schwarzrahmen and shoring devices which have such Sp Schwarzrahmen.
- Grabenverbauvoriquesen usually have shoring, which consist of two opposing, large-scale Verbauplatten, which support the trench walls. Such bogies can either be installed individually or strung together. In adjoining shingles the edges of the shoring are usually performed in opposing columns. Between the supports bending rigid expansion frame are arranged in height displaceable. For this purpose, the supports have horizontally extending linear guides.
- the supports with the vertical linear guides are usually integrated in the shoring panels. On each side edge of a Verbauplatte such a linear guide is arranged.
- the expansion frames are based on several, a vertical distance from each other having support points relative to the linear guides.
- the support points are usually formed by rollers.
- a shoring device with edge-guided shoring panels is for example from the European patent EP 0 619 853 B1 known.
- the Sp lanternrahmen two mutually parallel struts. These struts are connected by vertically extending and at different heights on the linear guide supporting carriage with each other. On each side of the Sp Schwarzrahmens a carriage between an upper and lower Sp Schwarzstrebe is arranged.
- Sp Drettillhornen which have the shape of an inverted U.
- the two lateral legs of the inverted U are formed by the two carriages.
- At the upper end of each carriage one end of the expansion strut is flanged.
- Such a Sp Schwarzrahmen allows a greater installation height of internals, especially pipes, which are installed in the channel, which is supported by the shoring device.
- the object of the invention is to develop a simple and inexpensive Verbauvorraum such that below a Sp Drhyroids a larger installation space remains.
- a connecting strut is attached to the ends of the spreading strut, which extends transversely to the spreading strut and is arranged at the lower end of one of the fastening elements.
- the fastening elements are arranged at the ends of the expansion strut, in each case with the interposition of a connecting strut extending transversely to the expansion strut.
- connection strut extends vertically, wherein the expansion strut extends horizontally.
- the guide member which is usually formed by the carriage, is arranged in a predetermined by the position of the linear guide height. Since the expansion strut now no longer extends directly between the guide members, but offset upwards between the attached to the guide links connecting struts, the clear space below the expansion strut can be significantly increased.
- the spreading strut can be raised, for example, by 1 meter.
- the connecting struts can simply be removed from the ends of the spreading strut and the guide members can be flanged directly to the end of the spreading strut.
- the system according to the invention is therefore extremely variable. It can be carried out either with direct attachment of the guide members at the ends of the spreader strut with normal passage height or when using the connection struts with increased passage height.
- the expansion strut and the connecting strut are usually made of metal profiles, usually made of steel.
- the ends of the expansion strut are bolted or welded to the connecting struts.
- the screw allows variable conversion of the expansion strut according to the invention by removing the connecting struts.
- the fastener may be on the connecting strut a flange plate with through holes for connecting screws.
- the holding element of the guide member may be formed by a complementary flange plate.
- the Spstrestrebenende may have a flange plate which is formed corresponding to that on the connecting strut. So the spreading strut can firstly directly and secondly under embglagung the connection bars according to the invention are screwed to the guide element.
- an additional fastening element can be arranged at the upper end of the connecting strut. For example, if additional sheathing panels must be placed to realize a deeper trench, a head portion can be attached to the additional fastener which holds the additional shoring panels.
- the invention relates to a spreader frame with two guide members, which are connectable to the sliding guide in each case with a linear guide a Verbauvorraum, and with a spreading strut described above.
- a connecting strut is attached to each end of the spreading strut, which extends transversely to the spreading strut and at the lower end of which one of the fastening elements is arranged.

Description
Die Erfindung betrifft eine Spreizstrebe zur Bildung eines Spreizrahmens für Verbauvorrichtungen gemäß dem Oberbegriff des Anspruchs 1 sowie mit dieser Spreizstrebe gebildete Spreizrahmen und Verbauvorrichtungen, welche derartige Spreizrahmen aufweisen.The invention relates to a spreading strut for forming a Spreizrahmens for shoring devices according to the preamble of
Grabenverbauvorrichtungen weisen üblicherweise Verbaufelder auf, die aus zwei einander gegenüberliegenden, großflächigen Verbauplatten bestehen, welche die Grabenwände abstützen. Derartige Verbaufelder können entweder einzeln eingebaut werden oder aneinander gereiht werden. Bei aneinander gereihten Verbaufeldern werden die Ränder der Verbauplatten üblicherweise in einander gegenüberstehenden Stützen geführt. Zwischen den Stützen sind biegesteife Spreizrahmen in der Höhe verschiebbar angeordnet. Hierfür weisen die Stützen sich horizontal erstreckende Linearführungen auf.Grabenverbauvorrichtungen usually have shoring, which consist of two opposing, large-scale Verbauplatten, which support the trench walls. Such bogies can either be installed individually or strung together. In adjoining shingles the edges of the shoring are usually performed in opposing columns. Between the supports bending rigid expansion frame are arranged in height displaceable. For this purpose, the supports have horizontally extending linear guides.
Bei einzelnen Verbaufeldern sind die Stützen mit den vertikalen Linearführungen in der Regel in die Verbauplatten integriert. An jedem Seitenrand einer Verbauplatte ist eine derartige Linearführung angeordnet.In individual shoring fields, the supports with the vertical linear guides are usually integrated in the shoring panels. On each side edge of a Verbauplatte such a linear guide is arranged.
Die Spreizrahmen stützen sich über mehrere, einen vertikalen Abstand zueinander aufweisende Abstützungspunkte gegenüber den Linearführungen ab. Die Abstützpunkte werden üblicherweise durch Laufrollen gebildet. Durch die beigesteife Ausbildung der Spreizrahmen ist sichergestellt, dass die einander gegenüberliegenden Verbauplatten zueinander parallel geführt und nur in vertikaler Richtung verschoben werden. Dabei wird jegliches Verkippen der Verbauplatten oder der Spreizrahmen vermieden. Dies führt dazu, dass die Verbauplatten sowohl beim Einbau als auch beim Ausbau stets den gleichen Abstand zueinander aufweisen. Erschütterungen, Kompressionen oder Auflockerungen des durch die Verbauplatten abgestützten Erdreichs werden so sicher vermieden.The expansion frames are based on several, a vertical distance from each other having support points relative to the linear guides. The support points are usually formed by rollers. By beigesteife training of Spreizrahmen is ensured that the opposing shoring plates are guided parallel to each other and moved only in the vertical direction. In this case, any tilting of Verbauplatten or Spreizrahmen is avoided. This means that the shoring panels always have the same distance from each other during installation and removal. Shakes, compressions or loosening of the soil supported by the lining panels are thus reliably avoided.
Eine Verbauvorrichtung mit randgeführten Verbauplatten ist beispielsweise aus dem europäischen Patent
Es sind aber auch Spreizrahmen bekannt, die die Form eines umgedrehten U aufweisen. Die beiden seitlichen Schenkel des umgedrehten U werden durch die zwei Laufwagen gebildet. Am oberen Ende je eines Laufwagens ist ein Ende der Spreizstrebe angeflanscht. Ein derartiger Spreizrahmen ermöglicht eine größere Einbauhöhe von Einbauten, insbesondere Rohren, die in den Kanal eingebaut werden, der durch die Verbauvorrichtung abgestützt wird.But there are also Spreizrahmen known, which have the shape of an inverted U. The two lateral legs of the inverted U are formed by the two carriages. At the upper end of each carriage one end of the expansion strut is flanged. Such a Spreizrahmen allows a greater installation height of internals, especially pipes, which are installed in the channel, which is supported by the shoring device.
Aufgabe der Erfindung ist es, eine einfache und kostengünstige Verbauvorrichtung derart weiterzubilden, dass unterhalb eines Spreizrahmens ein größerer Einbauraum verbleibt.The object of the invention is to develop a simple and inexpensive Verbauvorrichtung such that below a Spreizrahmens a larger installation space remains.
Diese Aufgabe wird durch eine Spreizstrebe mit der Gesamtheit der Merkmale des Patentanspruchs 1 gelöst.This object is achieved by a Spreizstrebe with the totality of the features of
Es wird eine Spreizstrebe für einen Spreizrahmen für Verbauvorrichtungen vorgeschlagen, an deren zwei Enden jeweils ein Befestigungselement zum Befestigen an einem komplementären Halteelement eines Führungsgliedes angeordnet ist. Das Führungsglied ist üblicherweise der Laufwagen.It is proposed a Spreizstrebe for a Spreizrahmen for Verbauvorrichtungen, at its two ends in each case a fastening element is arranged for attachment to a complementary holding element of a guide member. The guide member is usually the carriage.
Zur Lösung der Aufgabe der Erfindung ist an den Enden der Spreizstrebe jeweils eine Anschlussstrebe befestigt, die sich quer zur Spreizstrebe erstreckt und an deren unterem Ende eines der Befestigungselemente angeordnet ist. Mit anderen Worten werden die Befestigungselemente an den Enden der Spreizstrebe jeweils unter Zwischenfügung einer sich quer zur Spreizstrebe erstreckenden Anschlussstrebe angeordnet.To achieve the object of the invention, in each case a connecting strut is attached to the ends of the spreading strut, which extends transversely to the spreading strut and is arranged at the lower end of one of the fastening elements. In other words, the fastening elements are arranged at the ends of the expansion strut, in each case with the interposition of a connecting strut extending transversely to the expansion strut.
Vorzugsweise verläuft die Anschlussstrebe vertikal, wobei sich die Spreizstrebe horizontal erstreckt. Durch das Einfügen der vertikalen Anschlussstrebe zwischen einem Ende der Spreizstrebe und dem diesem Spreizstrebenende zugeordneten Führungsglied liegt die Spreizstrebe in eingebautem Zustand höher. Das Führungsglied, welches üblicherweise durch den Laufwagen gebildet wird, ist in einer durch die Lage der Linearführung vorgegebenen Höhe angeordnet. Da die Spreizstrebe nun nicht mehr unmittelbar zwischen den Führungsgliedern verläuft, sondern nach oben versetzt zwischen den an den Führungsgliedern befestigten Anschlussstreben, kann der lichte Raum unterhalb der Spreizstrebe erheblich vergrößert werden. Je nach konstruktiver Ausgestaltung von Spreizstrebe und Anschlussstrebe kann die Spreizstrebe zum Beispiel um 1 Meter angehoben werden.Preferably, the connection strut extends vertically, wherein the expansion strut extends horizontally. By inserting the vertical connecting strut between one end of the spreading strut and the Spreizstrebenende associated guide member, the spreading strut is higher in the installed state. The guide member, which is usually formed by the carriage, is arranged in a predetermined by the position of the linear guide height. Since the expansion strut now no longer extends directly between the guide members, but offset upwards between the attached to the guide links connecting struts, the clear space below the expansion strut can be significantly increased. Depending on the structural design of the expansion strut and connecting strut, the spreading strut can be raised, for example, by 1 meter.
Wenn eine derartig große Höhe unterhalb der Spreizstrebe nicht erforderlich ist, können einfach die Anschlussstreben von den Enden der Spreizstrebe entfernt werden und die Führungsglieder unmittelbar an dem Ende der Spreizstrebe angeflanscht werden.If such a large height below the spreading strut is not required, the connecting struts can simply be removed from the ends of the spreading strut and the guide members can be flanged directly to the end of the spreading strut.
Das erfindungsgemäße System ist folglich äußerst variabel. Es kann entweder bei direkter Befestigung der Führungsglieder an den Enden der Spreizstrebe mit normaler Durchlasshöhe ausgeführt werden oder bei der Verwendung der Anschlussstreben mit gesteigerter Durchlasshöhe.The system according to the invention is therefore extremely variable. It can be carried out either with direct attachment of the guide members at the ends of the spreader strut with normal passage height or when using the connection struts with increased passage height.
Die Spreizstrebe und die Anschlussstrebe bestehen in aller Regel aus Metallprofilen, üblicherweise aus Stahl.The expansion strut and the connecting strut are usually made of metal profiles, usually made of steel.
In der Praxis sind die Enden der Spreizstrebe mit den Anschlussstreben verschraubt oder verschweißt. Insbesondere die Verschraubung ermöglicht ein variables Umrüsten der erfindungsgemäßen Spreizstrebe durch Entfernung der Anschlussstreben. Zum Verschrauben kann das Befestigungselement an der Anschlussstrebe eine Flanschplatte mit Durchgangslöchern für Verbindungsschrauben sein. Das Halteelement des Führungsgliedes kann von einer komplementären Flanschplatte gebildet werden. Das Spreizstrebenende kann eine Flanschplatte aufweisen, die entsprechend derjenigen an der Anschlussstrebe ausgebildet ist. So kann die Spreizstrebe erstens direkt und zweitens unter Zwischenfügung der erfindungsgemäßen Anschlussstreben an das Führungselement geschraubt werden.In practice, the ends of the expansion strut are bolted or welded to the connecting struts. In particular, the screw allows variable conversion of the expansion strut according to the invention by removing the connecting struts. For screwing the fastener may be on the connecting strut a flange plate with through holes for connecting screws. The holding element of the guide member may be formed by a complementary flange plate. The Spstrestrebenende may have a flange plate which is formed corresponding to that on the connecting strut. So the spreading strut can firstly directly and secondly under Zwischenfügung the connection bars according to the invention are screwed to the guide element.
An dem oberen Ende der Anschlussstrebe kann ein zusätzliches Befestigungs-element angeordnet werden. Wenn beispielsweise zusätzliche Verbauplatten aufgesetzt werden müssen, um einen tieferen Graben zu realisieren, kann an dem zusätzlichen Befestigungselement ein Kopfteil befestigt werden, welches die zusätzlichen Verbauplatten hält.At the upper end of the connecting strut, an additional fastening element can be arranged. For example, if additional sheathing panels must be placed to realize a deeper trench, a head portion can be attached to the additional fastener which holds the additional shoring panels.
Gemäß einem weiteren Aspekt bezieht sich die Erfindung auf einen Spreizrahmen mit zwei Führungsgliedern, welche zur verschiebbaren Führung jeweils mit einer Linearführung einer Verbauvorrichtung verbindbar sind, und mit einer oben beschriebenen Spreizstrebe. Dabei ist an jedem Ende der Spreizstrebe eine Anschlussstrebe befestigt, die sich quer zur Spreizstrebe erstreckt und an deren unterem Ende eines der Befestigungselemente angeordnet ist. Befestigungselemente und Halteelemente bestehen - wie erwähnt - vorzugsweise aus Flanschplatten mit übereinstimmenden Lochbildern zum Hindurchstecken von Befestigungsschrauben.According to a further aspect, the invention relates to a spreader frame with two guide members, which are connectable to the sliding guide in each case with a linear guide a Verbauvorrichtung, and with a spreading strut described above. In this case, a connecting strut is attached to each end of the spreading strut, which extends transversely to the spreading strut and at the lower end of which one of the fastening elements is arranged. Fasteners and retaining elements consist - as mentioned - preferably from flange plates with matching hole patterns for passing through fastening screws.
Wie erwähnt, werden die Führungsglieder des erfindungsgemäßen Spreizrahmens vorzugsweise durch Laufwagen gebildet. Die Laufwagen weisen im vertikalen Abstand zueinander angeordnete Laufrollen auf, die dazu vorgesehen sind, auf einer Führungsfläche einer vertikalen Linearführung einer Verbauvorrichtung abzurollen. Die Linearführungen sind entweder an den einander zugewandten Seiten von separaten Stützen vorgesehen, welche jeweils die Ränder von Verbauplatten abstützen, oder in die Verbauplatten integriert.As mentioned, the guide members of the expansion frame according to the invention are preferably formed by carriages. The carriages have vertically spaced-apart rollers, which are intended to unroll on a guide surface of a vertical linear guide of a shoring device. The linear guides are either provided on the sides facing each other by separate supports, which respectively support the edges of Verbauplatten, or integrated into the Verbauplatten.
Das Führungsglied kann einen Rückhaltekörper aufweisen, der formschlüssig in einen Führungskanal der Linearführung eingreift. Dieser Rückhaltekörper überträgt Zugkräfte auf den Spreizrahmen und verhindert ein Verkippen der Verbauplatte, bei dem das untere Ende der Verbauplatte zur Grabenmitte hin gedrückt wird.The guide member may have a retaining body which engages positively in a guide channel of the linear guide. This retaining body transmits tensile forces on the expansion frame and prevents tilting of the lining plate, in which the lower end of the lining plate is pushed towards the trench center.
Vorzugsweise ist das untere Ende der Anschlussstrebe am oberen Ende des Führungsglieds befestigt, um eine optimale Erhöhung des Bauraums unterhalb der Spreizstrebe zu ermöglichen. Hierbei erstreckt sich die Anschlussstrebe von dem Führungsglied aus vertikal nach oben.Preferably, the lower end of the connecting strut is secured to the upper end of the guide member to allow an optimal increase in the space below the expansion strut. This extends the Connecting strut from the guide member from vertically upwards.
Das weiter oben erwähnte zusätzliche Befestigungselement am oberen Ende der Anschlussstrebe kann mit einem zusätzlichen Halteelement zusammenwirken, welches an einem Kopfteil angeordnet ist. Das Kopfteil ist in eine zusätzliche Linearführung einfügbar. Die zusätzliche Linearführung kann in der Praxis an einer zusätzlichen Verbauplatte angeordnet sein, die der Erhöhung des Verbaufeldes dient.The above-mentioned additional fastener at the upper end of the connection strut can cooperate with an additional holding element, which is arranged on a head part. The headboard can be inserted in an additional linear guide. The additional linear guide can be arranged in practice on an additional Verbauplatte, which serves to increase the Verbaufeldes.
Gemäß einem weiteren Aspekt betrifft die Erfindung eine Verbauvorrichtung mit zwei einander gegenüberliegenden, großflächigen Verbauplatten, an denen vertikale Linearführungen angeordnet sind. Gemäß der Erfindung ist zwischen zwei einander gegenüberliegenden Linearführungen ein Spreizrahmen der oben beschriebenen Art eingefügt.According to a further aspect, the invention relates to a shoring device with two opposite, large-scale Verbauplatten on which vertical linear guides are arranged. According to the invention, a spreader frame of the type described above is inserted between two mutually opposite linear guides.
Wie erwähnt, werden die Linearführungen vorzugsweise von mit der Verbauplatte verbundenen Stützen gebildet. Eine Stütze kann entweder einen vertikalen Rand der Verbauplatte aufnehmen und abstützen oder fest mit einem vertikalen Rand der Verbauplatte verbunden sein.As mentioned, the linear guides are preferably formed by supports connected to the lining plate. A support can either receive and support a vertical edge of the lining plate or be fixedly connected to a vertical edge of the lining plate.
Wie oben erwähnt, kann auf die einander gegenüberliegenden Verbauplatten jeweils eine zusätzliche Verbauplatte aufgesteckt werden, welche jeweils eine zusätzliche Linearführung aufweisen, in der eines der Kopfteile verschiebbar geführt ist. Das Kopfteil, welches am oberen Ende der Anschlussstrebe angeordnet ist, stützt damit die zusätzliche Verbauplatte ab und fixiert diese vertikal oberhalb der unteren Verbauplatte und mit dieser fluchtend.As mentioned above, in each case an additional lining plate can be plugged onto the opposite lining plates, which each have an additional linear guide, in which one of the head parts is guided displaceably. The head part, which is arranged at the upper end of the connecting strut, thus supports the additional Verbauplatte and fixes them vertically above the lower Verbauplatte and aligned with this.
